紫外线

These facts conflicted with current theory and were not explained until 1905, when Einstein produced his quantitative law and developed the theory of quanta of light or photons, which was verified much later by Millikan.

此后，莱纳德又继续拓展赫兹关于光电效应的研究，他分析了在高真空环境下光电效应的特性和本质，证明了当紫外线照射在金属上时，会使电子从金属表面逸出，并在真空中传播，电子在电场中被加速或减速，电子轨迹在磁场中改变。通过精确的实验，他证明发射的电子数量正比于入射光所带的能量，而电子的速度，或者说它们的动能，却与入射光能量无关，当入射光的波长减小时，电子速度增大。这个事实与当时的理论是相冲突的，经典物理学无法解释莱纳德的光电效应实验结果。

Early estimates on UV lifetime of the LCD are encouraging and we are now more confident that our target of 22K-hour lifetime can be achieved even under harsh conditions, such as the Libyan desert.

LCD紫外线寿命的初步评估令人满意，这使得我们现在对下一个目标——苛刻条件下寿命达到22k/h充满信心。

The somatic cell count of goat milk is higher than that of cow and sheep milk due to its apocrine secretory system.

山羊奶特殊的顶浆分泌机制使正常山羊奶的体细胞数要高于正常牛奶和绵羊奶。

Third, based on the example of over proof on-load loss in 180MVA/220kV power transformer, the eddy loss in winding is analyzed with the leakage flux element software. Some conclusions with practical use are given. In order to reduce the load loss, primarily we should reduce radial leakage flux of transformer possibily.

运用漏磁场分析软件，以180MVA/220kV电力变压器负载损耗超标为例，进行详细分析，提出有工程实用价值的结论：降低变压器负载损耗，从根本上应尽可能减少变压器辐向漏磁。
