多义线 meaning in Chinese

multiline
pline
poly-line

Based on the analysis of designed cad graphics and the given parameters , computer can convert the cad graphics to a acdbpolyline which can simulate the routine of the conveyor chain . then by using the method of point - by - point strain calculation , computer could figure out each point ’ s strain of the chains under different load states , and get the results such as strain ’ s maximal and the minimal values and their positions , weight of the strain equipment and power of the drive electric - machinery that the conveyor need
通过对设计的cad图形和给定参数的分析,将输送链运行轨迹转化为一条可模拟输送链轨迹的多义线,然后用逐点张力计算法动态地计算出各种加载状态下输送链上各点的受力,得出最大、最小受力点的力的大小和位置,拉紧装置的重量,驱动电机所需的功率等结果。
