Chinese character input is a theoretical and technical subject , At present, the five stroke input method has been widely used at home and abroad , It is generally acknowledged that it is a better method of Chinese character coding input .
1. The character of radical key position
Five strokes input method 130 Multiple radicals are divided into five areas and five digits , Arrange scientifically in 25 It's easy to remember the letters on the key , It's also easy to operate , Its characteristics are as follows ：
(1) Average per key 2-6 It's a basic radical , A representative radical becomes the key name , For the sake of memory , There is a song about key names “ Key name spectrum ”：
1)（ cross ） District ： king 、 soil 、 Big 、 wood 、 work
2）( vertical ) District ： Objective 、 Japan 、 mouth 、 field 、 mountain
3）( skimming ) District ： standing grain 、 white 、 month 、 people 、 gold
4）( si ) District ： said 、 state 、 water 、 fire 、 And
5）( fold ) District ： has 、 Son 、 Woman 、 also 、 On the way out
(2) The form of the radical on each key is similar to that of the key name .
for example ：“ king ” There's a... On the key 、 5、 ... and 、 Oh 、 、 Wang et al ; “ Japan ” There is a day on the key 、 yue 、 Good morning! 、 Worms, etc .
(3) The type and number of single stroke basic radicals correspond to location coding .
For example, one 、 Two 、 Three of these three single stroke radicals , They are arranged in 1 The first in the district 、 Two 、 In three positions ;
丨 、 Control 、 These three single stroke radicals are arranged in 2 The first in the district 、 Two 、 Three of you .
2． The location and mnemonic words of radicals
In order to remember the position of the basic radical on the keyboard , Wang Yongmin wrote a root word to help memory .

55X A loving mother has no heart bow and dagger Young and weak (“ Young ” Get rid of “ force ” by “ Unitary ”)
3．Z Key usage
It can be seen from the bitmap of the root key of the pentagram ,26 The first English letter key only uses A-Y common 25 Key ,Z The key is used to assist learning .
When it is difficult to determine which radical to use when splitting Chinese characters , No matter what radical it is, it can be used Z Key instead . With the help of software , Display all the Chinese characters in the prompt line , Then type in the corresponding number , The corresponding Chinese character can be selected to the current cursor position . In the prompt line, the five stroke code of Chinese characters is also displayed , It can be used to learn coding rules .
Four 、 Ways to speed up input
Generally, a Chinese character can be input by four keys . In order to speed up , The input methods of simple code and vocabulary code are designed .
1. Short code input
（1） First level simplified characters .
For some common high frequency words , You can input a Chinese character by tapping one key and then one space bar . High frequency words are 25 individual , As shown in the figure below, the top left corner of the key is the key name , The lower right corner of the key is a high frequency word, which is a simplified code word .
（2） Second level simplified characters .
It is composed of the first two root codes of single word full code followed by a space bar , You can enter at most 25×25=625 The Chinese characters .
（3） Three level simplified characters .
It consists of the first three roots of a single word followed by a space bar . Where the first three radicals are unique in coding , They are all selected as three-level simplified characters , It's about 4400 individual . Although the number of keystrokes has not decreased . But it's not necessary to judge the last code , Still helps speed up input .
2. Vocabulary input
The basic unit of Chinese character is character , Words are made of words . If you use words as the basic unit of input in a sentence , It's faster . The words in the five strokes are the same as the characters , It's still only four yards . Use the first one of the Chinese characters in each word 、 Two roots form a new code , Just like the code of a single Chinese character , To represent a word . The code rules of vocabulary code are as follows ：
（1） Doubleword ： Take the first two roots of each word to form a word code .
for example ：“ Calculation ” take “ said 、 Ten 、 Objective ” Make up the code （YFIH）;
（2） Three words ： Take one root for each of the first two words , The third takes the first two roots as the encoding .
for example ：“ operator ” take “ I'm sorry 、 People 、 mouth 、 shellfish ” Make up a code （RWKM）;“ People's Liberation Army ” take “ The knife 、 Fang 、 Yes 、 vehicle ” As a code （QYPL） wait .
（3） Four words ： Take the first root of each word as the code .
for example ：“ Programming ” take “ standing grain 、 wide 、 said 、 said ”（TYYY） Make up the word code .
（4） Many words ： Take one 、 Two 、 3、 ... and 、 The first root of the last four words is used as the component code .
for example ：“ The People's Republic of China ” take “ mouth 、 people 、 people 、 mouth ”（KWWL）,“ electronic computer ” take “ Japan 、 Son 、 said 、 wood ”（JBYS） etc. .
The characters and words in the five strokes are all four sizes . therefore , Words occupy the same coding space . The reason why words can be contained together in one , It's because of four keys per word , share 25×25×25×25 A possible word encoding , about 39 m , A lot of code is idle . For word coding , Because of the different distribution of the root combinations of words and characters , They occupy basically disjoint parts in the coding space of Chinese characters . So the input of words and characters is exactly the same .
3． Recoding and fault tolerance
If a code corresponds to several Chinese characters , These are called heavy codewords ; Several codes correspond to one Chinese character , These codes are called fault tolerant codes of Chinese characters .
In the five strokes , When you enter a duplicate code , The duplicate code is displayed in the prompt line , The more commonly used typeface is in the first position , And use numbers to indicate the serial number of the repeated codewords , If all you want is the first word , You can continue to enter the next word , The word automatically jumps to the current cursor position . Other repeated codewords should be selected by number keys .
for example ：“ Jia ” Word sum “ xi ” word , It's all broken down （FKUK）, because “ xi ” Chinese characters are commonly used , It comes first ,“ Jia ” The word is in the second place . If you need “ Jia ” For words, use the number keys 2 Choose .
To reduce reduplication , The less commonly used heavy codeword is designed as a fault-tolerant codeword, that is, its last code is modified to L, for example ： hold “ Jia ” The code of a word is defined as FKUL, Use this way FKUL Input , Then you get the only “ Jia ” word .
In Chinese characters, the writing order of some characters varies from person to person , In order to adapt to this situation , Multiple input codes are allowed for one word , These words are called fault tolerant words . In the input scheme of five strokes encoding , There are 500 Varied .
Five strokes of learning ４－－ How to find a radical
（ One ）、 The regularity of radical design and key partition , So that beginners can refer to the following methods to quickly find the root on the keyboard .
Word root , It is a relatively invariable structure formed by the cross connection of several strokes. It is called radical . Among the five strokes, the best one is 130 Two basic radicals , It's divided into five areas , Each district is further divided into five places .
Area 1 ∶ Horizontal pen 27 Kind of , branch “ Wang Tu's carpenter ” Five ;
Two district ∶ Put up the pen 23 Kind of , branch “ Murikota mountain ” Five ;
Three District ∶ Put aside the pen 29 Kind of , branch “ He Bai Yue Ren Jin ” Five ;
Four areas ∶ Hold up the pen 23 Kind of , branch “ Talk about water and fire ” Five ;
Five districts ∶ Fold up the pen 28 Kind of , branch “ I've already had a child ” Four ;
1、 According to the first stroke of the radical （ The first ） The area where the root can be found （ With a few exceptions ） Such as ：“ king 、 soil 、 Big 、 wood 、 work 、 5、 ... and 、 Ten 、 ancient 、 In the west 、 Go ” The first stroke of the book is horizontal （ code-named 1）, They're all in the second 1 District .“ standing grain 、 white 、 month 、 people 、 gold 、 bamboo 、 hand 、 use 、 8、 ... and 、 son ” The first stroke of the book is （ code-named 3）, They're all in the second 3 District .
2、 According to the second stroke of the radical （ Second pen ） Generally speaking , It's in place . Such as ：“ king 、 On 、 standing grain 、 said 、 has ” The second stroke is horizontal （ code-named 1）, They're all in the second 1 position .“ Go 、 mountain 、 evening 、 And 、 On the way out ” The second stroke of the book is discount （ code-named 5）, They're all in the second 5 position .
3、 The radicals formed by single stroke and its simple compound strokes , Its tag is equal to the number of strokes . Such as ：“ One 、 丨 、 A kind of 、 , 、 B ”： It's all in the corresponding area 1 position “ Two 、 、 、 冫 、 ”： It's all in the corresponding area 2 position “ 3、 ... and 、 、 A kind of 、 Well 、 Oh ”： It's all in the corresponding area 3 position .
4、 A few exceptions ： Yes 4 Root , namely ： force 、 vehicle 、 A few 、 heart , They're not in the front 2 The pen corresponds to “ District ” and “ position ”, It's not even in the first place “ District ” in , It's really because they're corresponding to “ District ”、“ position ” in , cause “ Fighting inside ”（ Cause a lot of code duplication ）, unpopular , I have to live in a foreign country . Fortunately, such a radical is only 4 individual , With a certain characteristic , It's easy to remember .
for example ：“ force ”： The pronunciation is LI, Therefore, in “L”（24） On key , It's true .“ vehicle ”： Its traditional characters “ ” And “ field 、 nail ” Close , And “ field 、 nail ”（24·L） Stay together , It's safe for all neighbors .“ A few ”： Shape and “ Oh ” Close , Put the two in one key （25·M） I've got a partner in my life .“ heart ”： The longest stroke is “ B ”, Put it in “51·N” key On , There's always a little bit of kinship .
（ Two ）、 According to whether the radical is a Chinese character, it can be divided into two categories .
The first category ： It is the root of Chinese characters String 5
━━ The root of Chinese characters ━━ Yes 98 individual
The first category is divided into “ Key name root ”、“ The root of Chinese characters ”、“ Single stroke radical ” Three categories .
1． Key name root ━━ Yes 25 individual gold 、 wood 、 water 、 fire 、 soil , Japan 、 month 、 state 、 mountain 、 field , Son 、 Woman 、 has 、 Big 、 people , king 、 work 、 mouth 、 also 、 said , white 、 Objective 、 standing grain 、 And 、 On the way out .
2． The root of Chinese characters ━━ Yes 68 individual Two dogs, three pigs, one hand , Sichuan Bayu Guangxi rice ; Five scholars used ancient carriage , Twenty seven seven nine sixty ; Xi dagger, bow and dish is a fight , My son said that I have already heard ; A little bit of strength , The bamboo knife has been used to kill the dead insects . Xiaofang is from Xinjiu stone factory , Yi Yao Jia Bei Wen .
3． Single stroke radical ━━ Yes 5 individual One 、 丨 、 A kind of 、 , 、 B .
The second category ： It is not the root of Chinese characters
━━ Non Chinese radicals ━━ Yes 136 individual
The second category is divided into “ Radical radical ” And “ Redaction radical ” Two categories .
1． Radical radical ━━ Yes 32 individual I'm sorry , Speed up your project delivery ; It's the same thing , It's not like .
2． Redaction radical ━━ Yes 104 individual 1 green 、2 leather 、2 On 、1 boss 、2 Antelope 、2 sheep 、1 Yes 、1 hundred 、1 especially 、1 want 、2 At the end of the 、1 plate 、1 common 、1 In the east 、2 go 、 1 this 、1 Occupy 、1 have 、1 skin 、1 The tiger 、1 In the 、1 return 、2 Qi 、3 and 、4 In the 、2 belt 、1 black 、2 once 、3 Dance 、1 Stop 、 1 Zhou
（ A simple code root word ） A lot of workers String 5
（ Second level simple code radical word ） The great son of the five directions stands in the water
（ Three level simple code radical word ） The queen of Yuebai mountain is on fire again ,
（ Four level code root word ） Rikoume is already rich in gold, wood and soil .
（ First level key name root word ） A lot of workers
（ Secondary key name root word ） Two three four five six seven nine , It's early , From rice to square heart , Child several hand knife stop
（ Three key name root word ） Yu Gong Ji Gu Er dagger ba , Bamboo dish factory --- Mending 20 、 Jinbunai 18 .
（ Four key name root word ） Xinsi inch rain night , He said Guangxi ： Sichuan dry stone dog shell , The body of the scribe beetle
In the process of typesetting , Some roots are always confused , such as “ 7、 ... and ” and “ Dagger ”, It looks like . Now let's talk about these similar shapes , Confusing radicals .
（1）“ 7、 ... and ” and “ Dagger ”、“” and “” Take out the rest of the two points 、“ ” and “ Yes ”.
These groups of roots are very similar , When splitting, you should pay attention to their different starting strokes , The location is related to the beginning of writing .
such as “ 7、 ... and ” The beginning is horizontal , So in 1 District , and “ Dagger ” I started with a fold , stay 5 District . Input like this “ dragon ” Word time , Start with , stay 3 District , So the word code is RHF, and “ the ” The second root of a word is horizontal , In the 1 District , So we take the word "sheep" as the background , code UDH.
We'll see “ army ” and “ horn ”, It's easier to distinguish .“ Yes ” The starting point is , stay 4 District P On the key position ; and “ ” The beginning is to write , In the 3 District Q On the key position .
（2）“ Oh 、 Go 、 Yi ” They're all in the same area , It's just that the tag number is different , When splitting Chinese characters, we should distinguish them according to the secondary strokes of the root . such as ：“ generation 、 Cut 、 money ” There is a near root in three words , Respectively “ Yi 、 Go 、 Oh ”,“ Yi 、 Go ” Every time the pen is folded , So in 5 On a , Location number 15;“ Oh ” The second pen is horizontal , So in 1 On a , Location number 11.
（3）“ Xiao 、 Drag 、 mau ” The strokes of these characters are different due to the oblique hook part . So choosing a radical is different .
“ Xiao ”： The diagonal part of the word is made up of horizontal 、 A diagonal hook 、 It's made up of , And radical “ Go ” It's like , But a little less , Can't be “ Go ” To deal with it , This part is related to “ 7、 ... and ” It's like , According to the principle of the big priority , Just take a root , therefore “ Xiao ” It can be divided into ：“ Japan 、 7、 ... and 、 A kind of 、 son ”, Encoded as JATQ.
“ Drag ”： The diagonal part of the word is made up of the diagonal hook 、 It's made up of , And “ Dagger ” be similar , According to the principle of priority , Think of it as “ Dagger ” The morpheme of ,“ Drag ” Split into “ Japan 、 Dagger ”, Identification code 33, code JXE.
“ mau ”： The diagonal part of the word is also made up of the diagonal hook 、 It's made up of , But you can't take “ Dagger ” As a variant radical , Because there's another point at the end of the word , In five strokes , In general, the characters with such a structure end with the apostrophe , The hook part of the word becomes the hook 、 spot 、 skimming , So we can't take “ Dagger ”, And take the fold as the root ,“ mau ” Break the word into “ acutely 、 factory 、 B 、 A kind of ”, code ADNT.
These words are not easy to distinguish , There are not many such words , The best way is to memorize these words .
（4）“ Oh ” and “ Yeah ” The deformation of radicals .
“ Ao ”： The second root stroke and the root of the word “ Oh ” be similar , According to the principle of the big priority , Take the second root as “ Oh ” A variation of the . such “ Ao ” Split the word into “、 Oh 、 A kind of ”, Encoded as GQTY. Similar words are “ Arrogant 、 Roam ” etc. .
“ Give ”： Above the word is the root “”, The second root is related to “ Yeah ” It's like , So the “ Give ” Split into “、 Yeah ”, Encoded as CBJ. Similar to that “ Spear 、 pre 、 The soft ” etc. .
