A, b, and c are curve-fitting constants in the curve equation y="1"–a×(1–x)c and the complementary-curve equation y="a"×(1–x)c, where a is a coefficient, b is the lower limit for x and is less than one, and c is a power constant.

对绘曲线装置，y为规一化输出位变量，x为非零平均值（小于1）到1的规一化输入模拟电压。a、b和c为用曲线方程y=1–a×(1–x)c拟合的常数，补充曲线方程y=a×(1–x)c，在此，a为系数，b为x的较低限制，且小于1，c为功率常数。

The purpose of the research was to obtain bacterial polyhydroxyalkanoic acids producers with good characters. With bottom sludge from Donghu Lake, bum soil from hillside, fertile vegetable soil and oil-soaked soil as initial samples, the bacterial strains with ability of synthesizing PHAs were screened not through enriching, isolation and purification, staining with Sudan black B and qualitative and quantitative analyses by infrared spectroscopy and gas chromatography. The results of staining with Sudan black B showed that there were 3 strains with ability of synthesizing PHAs among the 12 isolated strains and their numbers were Zj-5, Zj-8 and Zj-9 resp. All the 3 strains took on adsorption peaks at the points near 1741 cm^(-1) and the infrared spectrums of the strains Zj-8 and Zj-9 were similar.
