查询词典 prerequisite

In 1988, Song Dedun and Ding Jing further verified that the distributions whose inverse forms must be explicitly defined could by no means be a prerequisite for using the PWM method, and they applied PWM method successfully to the estimation of parameters in Pearson Type-Ill distribution (P-III distribution) although this sort of distribution nev...

由我国宋德敦、丁晶(1988年)将美国Greenwood等人(1979年)提出的概率权重矩法，应用于P-Ⅲ分布，取得较好效果。本文将PWM法应用于指数Γ分布的参数估计。统计试验结果和实例分析表明，PWM法用于指数Γ分布的参数估计时，具有较好的统计特性。

A solution to technology transfer and culture friction was given in this article The author thanked that according to the basic principle of universality and pertinacity of Techno-culture,during the process of implementing technology transfer,culture change and nationality of technology must be fraught into effect simultaneously,which was the practice approach of solution to the prerequisite of the latter

本文通过对技术转移与文化摩擦问题的研究，提出了自己的解决对策。作者认为，根据"技术-文化"的普遍性与特殊性关系的基本原理，在实施技术转移的过程中，必须同时实施文化变革和技术民族化，这是在技术转移中解决文化摩擦问题的实践途径。

他认为人类只有将自己从被传统侵蚀的精神和思维等虚伪文明中解放出来，才能建立真正圆满的两性谐和的新世界。

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。
