The focus is given to the influence of pumping power, cavity length, the output coupler transmission and initial transmission on the repetition rate, pulse width and output power of laser output.
着重研究了抽运功率、腔长、输出镜透过率以及初始透过率等因素对激光输出脉冲序列的重复率、脉冲宽度以及输出功率的影响。
Quantitative relations of the pump flow rate versus the ratio of diffuser length to width, the ratio of diffuser thickness to width, fluid viscosity and backpressure were also given.
还给出微泵流量与扩散管长宽比、厚宽比、液体粘度和进出口反压差的定量关系。
The increasing rate of width and length of primary leaves decreased obviously after 10 days planting. The leaves got their maximum areas after 15 days while L. sative was just at the 3nd instar stage.
经10天左右的培养，叶片长、宽度增长速率明显减慢，此时是接种斑潜蝇的最佳时机，15天后即斑潜蝇幼虫生长到3龄时，叶面积达最大。
