查询词典 conic function

C Thermally controllable light valves:As described above, the clearing temperature of PDCLCs can be increased by UV-curing because of the reduction of impurity concentration. Therefore, when the texture of a CLC cell in the UV-cured region are changed to focal conic one, the scattering of light from the sample is maximum. However, the clearing temperature of PDCLCs can be increased continually with continually irradiating with UV light onto the sample, but the scattering is unchanged.

当PDCLC照射紫外光的时间超过某一特定时间，则表面配向被聚合物薄膜破坏而达成散射态之穿透度最低状态，若持续照光聚合时，因仍然处於focal conic态，故穿透度不再改变，但单体聚合造成相变温度上升，直到单体全部聚合为止。

The results show that the density of gritstone is decreased gradually as the temperature increasing; so that it can be ignored; the longitudinal wave velocity is linearly decreased when the temperature increasing, and decrease rate of it follows the law of conic; R is one temperature point, which makes the law of tensile strength of gritstone after high temperature follows the law of parabola; and the maximal tensile strength appears when the operative temperature is R. After the temperature is higher than 700 ℃, tensile strength is small and change range is small when the temperature is increased.

结果表明，高温后粗砂岩的密度随试验温度的升高减小幅度很小，几乎可忽略不记；高温后试件中纵波波速的传播随温度升高基本呈线性降低，而减小率呈二次曲线规律变化；存在一个温度点R，使高温后试件的抗拉强度呈开口向下抛物线关系变化，且在R温度作用后试件抗拉强度达到最大；当试验温度大于700 ℃后，试件的抗拉强度变得很小，且当温度升高时变化幅度也很小。
