曝光时间,辐照时间
例句与用法
- For the construction of single - arch tunnel within cracked surrounding rocks , 8 tunnel models are set up to study the effect of the earth pressure distribution of the various surrounding rocks due to excavation . the relationships between the loosen zone of tunnel radial earth pressure and the tunnel diameter , the characteristics of surrounding rocks and the exposed time are revealed . it is showed that the pressure loosen radius is 1 . 2 ~ 2 . 0 tunnel diameters and the strongly loosen radius drops to 0 . 5 ~ 1 . 0 one for double lane tunnel
对于单拱破碎围岩隧道的构筑问题，作者设置了8个隧道模型，研究开挖对不同隧道围岩压力分布的影响，揭示了洞周径向压力的松弛范围与洞径、围岩特性、裸露时间的关系，得到双车道隧道压力松弛半径为1 . 2 2 . 0倍洞径，强烈松弛区半径为0 . 5 1 . 0倍洞径。 - The research about the critical technique includes : developing the radiation - hard ccd sensitive to the x and euv ray ; implementing the design of ccd driving clock and signal readout electronic using cpld ; implementing shutter design which can realizing 1ms - 10s exposing time
关键技术突破包括：完成x射线和极紫外波段都敏感的抗辐照型ccd技术设计，并利用cpld实现了非规则像素阵列ccd的驱动时序和读取电子学电路设计和调试：完成1ms 10s宽动态范围快门装置设计和调试。 - The content of fructose in the light - exposed cortex tissue of tuberous root of " tsuda " turnip was obviously higher than that in light - interrupted cortex tissue . the content of fructose was increased gradually along with the prolongation of light - exposing time and stabled at high content level . there were no evident changes for the content of other three sugars after light - exposing
津田芜菁周皮中的果糖含量，光处理明显高于暗处理，且随光照处理时间的延长果糖含量逐渐提高，并以较高的含量稳定下来；其它三种糖含量光处理前后无明显变化。 - There was distinct difference for the expression patterns of chs gene in light - exposed and light - interrupted tissues of light - dependent " tsuda " turnip . light - exposing the tuberous root of " tsuda " turnip grown under dark condition , the expression quantity of chs gene was gradually increased along with the prolongation of light - exposing time . this indicated that the expression of chs gene was induced by light , and the expression quantity was positively correlated with accumulation of anthocyanin
3 ， chs基因的表达，在光敏感型津田芜菁的光处理与暗处理之间有明显的差异；对津田芜菁地下根暗处理部分再进行光照处理，随光照处理的时间延长， chs基因的表达量也逐渐提高，说明chs基因的表达受光诱导，且表达量与花青素的积累呈正相关。
