对定制需求提出了一种网状树形分解结构模型，表示定制需求的属性类别及其继承关系，采用树形结构的节点表示需求的属性和粒度，有助于准确把握客户定制需求。

The reason that zero can not be divisor, is right?Feng XinkongIn the eighth book of six-year primary school's teaching in nine-year compulsory educationmaterials, it states that "zero can not be divisor". But we can find that the formula, a=cq, checking the dividing exactly , is same as the form of direction proportion function, y=kx; the formula of checking the dividing not exactly, a=cq+r, is same as the form of simple function.

在九年义务教育六年制小学教科书《数学》第八册中规定"零不能作除数"，但是当我们学习了正比例函数和一次函数之后就会发现，验算能整除的除法的关系式a=cq和正比例函数y=kx的表示形式相同；验算有余数除法的关系式a=cq+r与一次函数的关系式y=kx+b的表示形式相同。
