预行 meaning in English
put in force beforehand; apply beforehand
Examples
- A study on electronic control system for variable pre - stroke fuel injection pump of automotive direct injection diesel engine
车用直喷式柴油机可变预行程泵电控系统研究 - Furthermore , the influences on four major characters of scholarly communication by e - preprint were discussed
最后，分析学术传播中主要的角色因电子预行本的出现所受到的影响。 - Titanium and titanium alloys - forging stock and forgings - technical specifications - pre - production and production forgings
钛和钛合金坯料和锻件技术规范.第3部分:预行生产锻件和生产锻件 - For example , the application of e - preprint combined with its server system becomes a possible solution for scholars who trapped in the repetitious publication process and not ideal peer review mechanism
电子预行本及其伺服系统的出现即是一个显著的例证，该机制让学术社群中的成员在冗长的学术出版与不尽完美的审查制度中，找到另一个可行的出路。 - A method based on the application of an injection process analysis software is introduced in this article , which optimize injection process through changing the design of fuel - injection pump cam . a model of 1115 single cylinder direct injection diesel engine is used as an example . with the help of pre - journey optimization , increasing cam lift and using tangent - function can make the matching of the injection system with the diesel more reasonable . without changing fuel pump installing size , it can enhance injection rate and injection pressure and improve the diesel operating stability in low speed condition
本文以国产1115型单缸直喷柴油机为例，介绍一种应用喷油过程分析软件改进喷油泵凸轮设计的方法，通过增大喷油泵凸轮升程、采用切线函数凸轮并优化预行程的方式，在不改变喷油泵安装尺寸的前提下，可提高喷油压力和喷油速率，改善柴油机低速工作稳定性，使喷油系统与柴油机匹配更合理。
