HPLC method of determination of CCU has been developed for the kinetic study. The kinetics of photodecomposition of CCU in various carrier gases have been studied. The photoreaction of CCU in nitrogen and air is of the first order, while in oxygen is closer to that of the second order. The rate constants in nitrogen, air and oxygen are 0.00703/h, 0.0109/hand 0.00445 , and the half-livies are 98. 6, 63. 6 and 62. 7hour respectively.

采用以甲醇一水为流动相的反相HPLC作为分析手段，对灭幼脲在不同载气中的光解动力学作了研究，结果表明，灭幼脲在氮气和空气中的光解反应符合一级动力学形式，而在氧气中的光解则更接近于二级反应形式；在三种气氛中的反应速度常数分别为0.00703h〓，0.00109h〓和0.00445h〓〓，半衰期相应为98.6、63.6及62.7h。

PLI integrates two approaches of "Focus on Form" and "Focus on Forms", and combines the consistency and systematicity of well-designed vocabulary teaching with the flexibility and adaptability of incidental learning, so that it can be better oriented toward EFL lexical instruction in China .

PLI 整合了 FFI 所包括的兼顾意义和形式的" Focus on Form "以及关注纯语言形式的" Focus on Forms "两种教学法，将附带性词汇习得与计划性词汇教学的优势融于一体，并将其计划性元素扩展到教学大纲、学习环境和评估测试等宏观层面，使之对我国讲授型外语学习环境下的词汇教学更有针对性和指向性。

The data in traditional information management on oilfield is generally provided as plotting paper or vector figure, which is difficultly maintained or commonly shared.

油田传统信息管理中数据一般以图纸或矢量图的形式出现，其更新维护、资源共享相当麻烦，无法满足油田地面规划、生产决策的实际需求，该系统提出使用卫星影像图作为油田的数据表现形式，并基于WebGIS技术在网络上对其发布。

Also, US spoken usage sometimes, especially with the contracted forms, substitutes the conditional for the pluperfect ( If I would have cooked the pie we could have had it for lunch ), but this tends to be avoided in writing.
