价格系数 meaning in English

cost coefficient

The author ' s main contributions are as following : first , an integrated performance index function of circuit products is constructed , and a continuous and differentiate price function is proposed accordingly . based on the mentioned and practical factors , such as market supply and demand , the continuous price function is dispersed and circuit products are classified into several classes
主要研究结果如下：首先，构造了一个电路综合性能指标函数，据此函数合理地构造了连续可导的价格系数函数，并在此基础上，结合市场的供求和其它实际情况对连续价格函数进行离散化及对电路产品进行分档。
