Solar energy photoelectric cell is a device to utilize the photon energy from sunlight to make the irradiated electrolyte or semi-conductor material move so as to generate voltage and also called photoelectric effect.

太阳能光电池是利用太阳光的光子能量，使得被照射的电解液或者半导体材料的电子移动，从而产生电压，这称为光电效应。

The theory of optically activated charge domain is adopted to analyze both the output characteristics and the photoelectric threshold condition of the semi-insulating GaAs photoconductive switch under the non-linear operational mode.

用光激发电荷畴理论分析了半绝缘GaAs光电导开关在非线性工作模式下的输出特性和光电阈值条件。

Based on the conclusion of experimental law, the photoelectric threshold condition is obtained for the semi-insulating GaAs photoconductive switch under the non-linear mode, pointing it out that, when the optic-energy triggers off the switch to meet the prerequisite that n_0L is greater than or equal to 10~(12)cm~(-2), the necessary condition is achieved for high field domain and meanwhile the threshold electric field serves to produce charge transmission effect within the material.

在总结实验规律的基础上，得到半绝缘GaAs光电导开关非线性模式的光电阈值条件，指出当光能触发使开关满足n0L≥10~(12)cm~(-2)时，达到形成高场畴的必要条件，阈值电场的作用是使材料体内产生电子转移效应。

Some researchers believe that the latter area possesses savanna vegetation. Savannas are closely associated with seasonal drought, and they may be defined by climatic climax vegetation in tropical and subtropical areas. Based on the ecoclimatic analyses as well as the surviving vegetation in Taiwan, we inferred that the potential natural vegetations of these 2 semi-arid regions were not savanna but forest with some drought-deciduous trees. In conclusion, the physiognomic type of grassland dotted with trees may occur in small areas at present, but Taiwan lacks climate-shaped savanna climax vegetation.

本研究将疏林定义为分布於热带及亚热带之气候形塑的极相植群，气候分析结果表明台湾半乾旱区域之缺水逆境并不严重，再配合现生残存植群之观察，发现台湾有形相为疏林的现生局部性植群，但其潜在自然植群应为参杂有乾旱落叶之阔叶树种的森林，并不存在较大面积之潜在的气候型极相疏林。

Such a picture box packed finished cross-stitch price is $800, embroidered semi-finished price is 160 yuan.

这样一幅装好框的成品十字绣售价是800元，没绣好的半成品售价则是160元。
