It proved that yellow-mutant belongs to the type of absence of chlorophyll; etiolation had relation to the lack of chlorophyll.The biology characteristic of the yellow-mutant cultured in vitro was investigated. The results showed that the mutant behaved etiolation character in different temperature and illumination time condition.

在离体培养条件下，探讨了桑树黄化突变体的生物学特性，发现在不同温度及光照条件下均表现黄化特征，证明该突变体叶色黄化与否与温度变化无关，不属于温敏型或光敏型叶色突变体，但突变体的黄化程度受温度影响而有一定的变化。

In conclusion, the lag phase of Streptococcus thermophilus was shorten in the eutrophy culture medium, and the time achieving the culminated point of logarithmic phase was shorted also, at the same time, the stationary phase lengthened. After secondary culture, Streptococcus thermophilus reached directly the log phase hardly through the lag phase, and then quickly reached the decline phase. There were more relations of the metabolic regalities of the three kinds of nutritive substances with the super-concentrated incubation process of Streptococcus thermophilus: the more the number of the bacteria, the quicker the metaboling, while the fewer, the slower the metabolism. Moreover, there apparently existed morphologic changes in this course, and there maybe existed the apoptosis, which correlated with bacteria propagation and acid producing. With the culture time postponed, the nutritive substances in the culture medium lacked also, and the morphologic change and apoptosis appeared more obviously.

结果表明，嗜热链球菌在营养丰富的培养基中的生长延滞期缩短，到达对数生长顶点的时间变短，稳定期的时间延长，当经过二次培养后，嗜热链球菌几乎不经过延滞期直接到达对数期，平稳期持续的时间较短，很快到达衰亡期；嗜热链球菌在超浓缩培养过程中三大营养物质的代谢规律也同它的培养过程有很大的关系，菌数多，其代谢旺盛，菌数降低其代谢速度减慢；嗜热链球菌在超浓缩培养过程中存在着明显的菌体形态变化，并可能存在着细胞凋亡，与菌体增殖和产酸规律密切相关，随着培养时间延长，培养基中营养物质变得贫乏，菌体形态变化和细胞凋亡的情况愈加明显。

Evaporation and relative humidity were reduced to decreased, but the change is not very obvious.

蒸发量和相对湿度的变化趋势为减少，但变化不是很明显。

Now if you run two smarts into each other than sure the smart's are safer than the lincolns, but when unevenly sized vehicles colloid physics dictates that the smaller vehicle experiences a much larger change in velocity, and thus a much larger change in momentum for the occupants, which requires exorbitantly more crushable zones to compensate for compared to the heavy car.

现在如果您运行两个智慧互相比确保智能的是安全性的林肯，但不均衡的大小车辆胶体物理告诉我们，规模较小的车辆经验一个更大的变化速度，因此，一个更大的变化势头占用，这就要求过高更挤压区，以补偿相比，重型汽车。

Intergovernmental Panel on Climate Change and other scientific assessments of climate change, which involve thousands of scientists producing massive and comprehensive reports, have, quite expectedly and normally, made some mistakes.

联合国政府间气候变化委员会和对气候变化的其他科学评估，有数千名科学家参与，产生了大量和全面的报告，也产生了一些错误，这是不出意料和很正常的。

合国政府间气候变化委员会和对气候变化的其他科学评估，有数千名科学家参与，产生了大量和全面的报告，也产生了一些错误，这是不出意料和很正常的。改：产生了数量巨大，范围广泛的报告。

It is found that the former provide more uneven circular stress state than the latter after comparing the circular stresses both of intrados and extrados,which extrados stress is large and intrados stress is small.That is confirmed by the results of experiment that the practical burst pressure...

结论认为，内压作用下的弯管结构属于有力矩旋转壳，整体环壳第二弯曲半径由外拱区的正半径变化为内拱区的负半径，引起应力性质的变化，只考虑薄膜应力的弯管内压爆破理论存在不安全的因素。
