Commercial agreement (including financial field, legal field etc.) is mainly made up of four parts, contract stem, contract text,
Contract afterbody, contract annex.Contract annex is mainly the data for details such as standards outside contract text, wouldn't belong to conjunction
About formation range, contract afterbody are mainly the signature column of contract, are safeguarded by the execution mechanism of contract, not told about here.Therefore,
For contract, most important work is exactly the design treatment of pairing about stem and contract text, and the text of contract is more
It is crucial.
Contract stem is exactly the content before written contract clause, primarily with respect to the identity of contract both sides, contract title, is closed
The about information such as numbering is illustrated and confirmed.
Contract text has the characteristics that：
(1) contract text is the agreement that both sides reach, and is presented mostly in the form of clause, and is compiled with regular sequence number
Agreement terms are arranged, therefore, contract text is detachable；
(2) agreement terms in same field suffer from greatly similar clause, for example the contract of financial field necessarily has friendship
Easily, the basic clause such as inquiry, therefore, same domain contract function can be approximate；
(3) agreement terms of congenerous are mostly approximate or even identical, and difference part is often presented in quantity, quality,
The quantifiable standard such as party, cost, time, therefore the quantized values of contract and condition can be changed, the standard of contract can increase
Subtract；
(4) do not have close relation between clause, it is most to make an appointment all independently of each other, without reference to each other, therefore,
Agreement terms are relatively independent.
