A two-dot sampling method of SPWM with nonsymmetrical rules was presented. It made the generation time and width of pulse closer to the nature sampling method, so the content of output humorous wave was reduced effectively.

提出一种两点式不对称规则SPWM工程采样法，使脉冲发生时刻和宽度更接近于自然采样法，从而可有效地降低输出谐波含量。

According to tests of colony formation days on plate and generation time determination, all strains were primary clustered into two groups: one is fast-growing rhizobium, the other is slow-growing rhizobium.

根据菌落形成时间和代时测定结果，将供试菌株初步划分为快生菌株和慢生菌株两种类型。

The research presents that the melanic mudstones are not very thick and organic carbon index is low in this member, but the type of organic matter is good with the features of high hydrocarbon generation potential and early hydrocarbon generation time.

研究表明，该段暗色泥岩虽然厚度不大，有机碳指标较低，但有机质类型较好，具有生烃潜力高、生烃时间早的特征。

Population double time decrease rapid with temperature rise in the section of low temperature, it postpone when temperature is 34 ℃, average generation time increase with temperature assume exponent.

种群加倍时间随温度升高在低温区急剧缩短，但到34℃时有所延长；平均世代时间随温度升高呈指数缩短。

Have obvious differences in resistance to antibiotics. After generation time determination and tests of colony formation days on plate for the 53 separated and purified strains of nodule bacteria from Acacia spp.
