The properties of 33 structure units are stored in computer memory and at all times being recalled to construct the main chain and side chain structures in the desirable polymer repeating unit. Then the above four physical properties of polymers can be calculated by computer program. 33种结构单元的性能存贮于计算机内,可以随时调出用以构造所要求的聚合物重复单元中的主链与侧链结构,然后由计算机程序计算聚合物上述4种物性参数。
On one hand, the computer system is based on the logic gates to implement its functions, in many cases, the operands passed repeatedly between the memory and the arithmetic logic unit must via the logic gates. 另一方面,计算机系统是基于逻辑门来实现的,在许多情况下,必须利用逻辑门在存储器与算术逻辑单元之间反复传递操作数。
