研究表明，NTC多晶氧化物半导体的电导是由晶粒中载流子的热激发并穿过晶界势垒形成的，电导同时受晶粒和晶界的控制；材料的电阻–温度特性不是严格的指数曲线；材料常数与温度有关。

The results indicate that the crystallinity of the samples can be improved with suitable doping concentration.

结果表明，适当的掺杂量可以改善CdTe薄膜的结晶性能，降低晶界势垒高度，提高其导电性能。

The measured results show that the shape of the yield curves changes with increasing illumination time due to the faster quantum-yield degradation rate of low energy photons.

基于修正后的反射式阴极量子效率公式对这种变化进行了理论分析，发现与光电子的谷间散射和阴极衰减过程中表面势垒形状的变化有关。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
