back layering meaning in Chinese

回流层现象

Backing layer castable is noted for low heat conductivity , good quality of being a whole part and good erosion resistance to mental steel
久衬浇注料整体性好、不开裂、导热率较低，且具有一定的抗钢水和铁水侵蚀能力。
The middle layer is the output of the former layer and the input of the back layer . it records the middle results when users use the former layer to develop embedded application system
中间接口层则是前台的输出，纪录了用户在使用前台开发嵌入式应用系统时的中间结果，也是后台的输入。
The back layer was founded based on analyzing , abstracting , modeling mass embedded systems . it combines with the middle result produced by the former layer and the back sustaining library to make out the aim system
后台则建立在分析、抽象、模块化、参数化大量嵌入式系统的基础之上，它结合前台产生的中间结果和后台支持库，产生最终的目标系统。
First , this dissertation discussed the necessity of developing stratagem based on platform , and established a devising platform for embedded system , which has three - layer structure including former layer , middle layer and back layer
在回顾、分析了嵌入式系统当前状况，展望其美好前景的基础上，本文首先论述了平台开发战略的必要性，并构造了一个分为前台、中间层、后台三层体系结构的嵌入式系统开发平台。
