Concurrent Engineering absorbs computer technique , database technique , network technique under the support of CAD, CAM, CAPP and CAE, considers conception form , scheme analyses , detail design, production, after service , production rejects all factors, resolves effetely lots of defects such as difficulty of data exchange , design changing frequently , cost high, long cycle for design and so on.

摘要并行工程是在CAD，CAM，CAPP和CAE等技术支持下，吸收了当前迅速发展的计算机技术、数据库技术、网络技术，在设计时综合考虑产品开发中的概念形成、方案分析、详细设计、生产制造、售后服务、产品报废等所有因素，有效解决了系统之间数据交换难，设计更改频繁，成本高，设计周期长等缺点。 DFM是并行工程的关键技术之一，在设计一开始就把制造系统的因素添加到设计过程中去，并从制造可行性的角度对设计进行分析评价，使设计满足制造要求，降低加工时间和生产成本。

But the massive project practice proved these technical measure the application fundamentally has not solved the rut problem; Regarding the city"urban heat island effect"the question, the measure which uses generally is enhances the city round-off work and the expanded lawn, the water place area, but the city major part area is constructed and the path is covering, the ultra big city its round-off work extremely is in particular difficult to enhance, simultaneously the spatial distribution very is possibly imbalanced.

但是大量的工程实践证明这些技术措施的应用也未从根本上解决车辙问题；对于城市"热岛效应"问题，普遍采用的措施是提高城市森林覆盖率及扩大草地、水地的面积，但城市的绝大部分面积被建筑和道路覆盖着，尤其是超大城市其森林覆盖率极难提高，同时空间分布可能又很不均衡。

Trying to solve the problem of 'difficult to see a doctor and expensive to see a doctor' as a matter of fact is to treat means as the goal, which disproportionally uses tax payer's money to protect the interest of a smaller group of population, scarifying a larger group of population (relatively disease-free group).

解决群众反映较多的"看病难、看病贵"问题的做法实际上是把手段之一当成目的了。把手段之一当成目的的结果是不成比例地强调了一部分人的利益，侵害或牺牲了大部分人的利益。

The requirement of control system specification constantly and diversely changes which results in the problem that the control software is hard to program and test. In order to deal with the problem, the theory of control system design based a high level extended Petri net is discussed in this paper.

为了解决现代控制系统的规模越来越大，柔性要求越来越高，所导致的控制软件的编制和调试越来越难的问题，本文主要探讨了基于一种高级扩展Petri网的控制系统设计理论。

Passive cooling system is composed of multiple sets of fans, which can remove the heat of LED beads adequately even in high room temperature conditions. Besides, KEY's tooth optical cooling technology, completely solved the high-power LED thermal problems.

目前大功率芯片以1W~3W为主。5W以上的单颗LED全由1W或3W合成，能合成10~50W的单颗灯珠，但其需要超大型散热器加风扇来减少光衰，但散热和光衰还是难以控制，可能在3-5年内也难在技术上解决合成灯珠发热太高的问题。

The results show that it can recognize reservoirs within 3 to 6 m, solve the difficult problem of the thin-bedded alternation sandbody identification and receive better exploration and development efficiency.

结果显示，反演可以识别3~6 m的储集层，解决了砂体薄互层识别难的问题，获得了比较好的勘探及开发效果。

At present this VC, PE heats up China only then at 2006, 2007, two this years nice to the benefit of VC, PE element cashs in succession: Cent buy reform solved equity to exit difficult obstacle; Do poineering work board the anticipation that roll out; Field of A stock market takes a cattle, point to soare; The electric power of cent numerous medium, Baidu, Meng Niu, Shang De stimulation that exits case to earn a few times at every turn is waited a moment.

中国目前这波VC、PE热始于2006、2007年，这两年对VC、PE的利好因素陆续兑现：股权分置改革解决了退出难障碍；创业板推出的预期；A股市场走牛、股指暴涨；分众传媒、百度、蒙牛、尚德电力等退出案例动辄赚几十倍的刺激等等。

The semi-aerobic landfill can eliminate the pollution of nitrogen in the landfill by means of its self-disposal function in a shorter period within the laboratory simulated conditions. This supplies an important idea and way for solution to the problems of high concentration of ammonia nitrogen being difficult to treat in leachate in the middle and final stages.

在室内模拟条件下，准好氧填埋完全能够在较短的时间内利用自身的处理功能，去除垃圾中氮污染，这为解决传统填埋场中后期垃圾渗滤液氨氮浓度高、处理难的问题提供重要启示和有效途径。
