We denote many typical arithmetics with apla , such as , non - recursive tree traversals , dijkstra , topological sorting etc . the test result indicates the program transformer can improve the program ' s reliability and development efficiency . it can replace softeware blue collar to complete mechanical and creative work 5 、实现了自动转换系统的泛型问题中的类型参数化问题，解决了apla提供泛型机制，而java语言不支持泛型机制的矛盾。
In addition , we also develop any algorithm program by using the par method and the transforming system . the c + + class library and apla - c + + transforming machine compose the apla - c + + system with high reliability , which has transformed many examples correctly , and the running results are correct 利用par方法自扩展生成的c + +类库与apla - c + +转换器共同组成具有高可靠性的apla - c + +自动转换系统，成功地转换了大量的实例，并得到了正确的结果。
Nowadays , bioenergy is a mature technology which , in its several facets using modern biomass or conversion systems , provides a significantly greater contribution towards the state primary energy supply than do all the existing and planned wind and solar projects together 目前,全球生物质能转换技术已经相当成熟,在转换过程的各个方面都应用了先进的生物质能转换系统。在我国的一次能源供给中,生物质能供给量超过了现有和正在计划的风能和太阳能供给量。
Above all , the paper offers the detailed introduction for the hardware system of mould industry and electric spark machining . this article sets forth the thought requirement , the principle of recording , the thought of realizing , the puzzles in designing and the process of adjustment during collecting course , conversion system between light and electron in the track system of optics 为此，本文对模具工业生产及数控电火花线切割机的硬件系统做了详细的介绍，重点阐述了光学跟踪系统中光电转换系统的设计及数据采集、处理软件的整体要求，记录原理，实现思路，设计过程，以及调试误差分析。
The conceptual design of a lighting system using sea waves as the energy source demonstrates that the proposed approach can not only maintain tile consistency of input and output energy objects in detailed features , but also achieve efficient synthesis of solutions with aid of tile shortest path knowledge and other heuristic knowledge 一种海浪照明系统的概念设计实例证明：该模型不但能在复杂能量转换系统的概念设计过程中正确考虑输入输出能量对象在细节特征上的匹配性，增强组合解的可行性，而且能借助最短路径知识和其他启发式知识较迅速地从知识库中找到合适的组合原理解。
Most systems are developed with its own account management sub - system , so a user must repeatedly input his username and passwords while switching in different systems . it not only increases the users ’ burden , but also increases the crisis of being embezzled , and the security of system will be reduced correspondingly 但是每个应用系统都有一套自己的用户管理方案,用户在转换系统时不得不重新输入用户名和密码,这不仅增加了用户的使用负担,而且还增加了用户帐号泄密的危险,降低了系统的安全性。
