optimum spectral band

This paper reported a method in determination of the optimum diaphragm of a tool microscope through experiment, and gained a good result.

本文介绍了通过实验确定工具显微镜最佳光阑的方法，并取得了很好的效果。

The optimum illumination time was 12 hours each day (fluorescent light, 40W; interval: 30cm ).

结果表明,拟茎点霉产孢的最佳培养基为苜蓿煎汁+Czapek培养基,其次为燕麦片琼脂培养基和苜蓿杆+水琼脂培养基;最适温度范围为22~25℃;最佳光照时间为每天12h(日光灯40W,与培养物间的距离约为30cm);合适的pH值范围为5。
