This, SARFT has issued a circular to remind operators to note that national standards are not tested before the promulgation of the system, must be modified for future ability to meet national standards;, therefore, to carry out ground-based mobile digital TV receiver test has a certain degree of technical risk and economic risk, I hope only in the approval of the individual areas tested.

为此，国家广电总局已发出通告，提醒经营者指出，国家标准是不测试前颁布的制度，必须为未来的能力，以满足国家标准修订，因此，开展地面移动数字电视接收机测试在技术上的风险和经济风险一定程度上，我只在个别地区的批准，希望测试。

M from electrostatic precipitatorys in power station as the test powder, experimental studies were made on the collection efficiency , pressure drop of the circumfluent cyclone and B-type high efficiency cyclone.

针对目前工业除尘器除尘效率低和经济上、技术上的一些难题，以电厂静电除尘除下来的粉煤灰和空气作为物系，测试了环流式旋风除尘器的分离效率和压降，并推导了环流式旋风除尘器分离效率的数学模型。

Digital image processing technology,the present reseach level about image alarm system is to separate eyewinker from monitoring image,and to judge whether the eyewinker is harmful according to the size of the area of object,this method is imprecise and suspectable.The image recgnition alarm system isan apply on image processing technology.when a foreign object enter monitoring place,we will segment、measure object,and analysis、judge through proportion characer or invariant monent.the result of the parameter will decide whether the eyewinker is harmful,if the object is harmful ,system will auto-startalarm device.

而本设计的主要特点是基于了数字图像处理技术，目前传统图像报警系统的研究水平是将异物从监控图像中分离出来，然后依据异物面积的大小来判断异物是否有害，它对异物有害的判断十分不准确，这种判断结果的有效性是很值得怀疑的；针对于这些弊端，本课题在数字图像处理技术上的应用是对监控场所进行全景监控，如有异物进入，对异物进行分割、测量，从不同的角度进行了分析和判断，进而决定异物是否有害，若满足场景所规定的有害条件，则启动报警装置，发出报警信息。

This is because the transformation is not continuous between splay alignment to bend alignment.

而此模式在技术上的主要问题就是液晶分子从splay排列到bend排列是不连续的，在这两个状态间存在一个临界电压，因此在这两个状态的切换间就必须克服一个很大的能障，所以就需要花上一段时间，而且在低电场时Bend的排列会比较不稳定，应用在显示器上是不方便的。

As for the reason, the phenomenon of industrial clusters comes into being owing to aseries of social and cultural factors that lies in the final products such as technologicalclassification, the possibility of product difference, the interconnection of technologicalinnovation, the taciturnity of knowledge, the dynamic changes of the competitiveenvironment of enterprise and the economy of development, the low transportation costof the final products, and the fashion and artistry.

究其原因，产业集群现象的出现是由于多方面因素的综合作用而造成的，其中包括产品存在着技术上的可分性、产品具有差异化机会、技术创新的网络性、知识的缄默性，以及企业竞争环境的动态多变和速度经济性、集群产品的低运输成本并具有时尚性和艺术性等一系列社会文化因素。

The first source of stress is Mercury Retrograde and thisone is packed with snafus, mechanical, technical andcommunicational.

Thisdistributive technology of belt conveyor line's program control, not only canbe economized capital and raised productivity but also is in the lead in ourcountry.

而且其更重要的意义的在于这项技术的成功运用，能使国内各行各业的运输装卸作业中节约大量资金，填补国内在这项技术上的空白。

Sprint speed affects the results achieved over the first 4-5 hurdles more than does perfection of technique and therefore considering the lack of significant difference in hurdling technique for world class hurdlers, it appears that the better sprinters will have an advantage over the first part of the race.

在跨越前4-5栏时快跑的速度比技术的完美更能影响到结果，因此鉴于世界级跨栏选手在跨栏技术上的高度同一性，更好的快跑在比赛的第一阶段显得尤为重要。

This article mainly introduced the city guard rail sweeps clear the vehicle in the development present situation and the present technology insufficiency, has analyzed the domestic formation product technical characteristic and the good and bad points, obtains the present water spray vehicle chassis situation through the contrast, then chooses this design through the analysis comparison each kind of plan, for instance said obtains the hydraulic transmission through the crosswise comparison to teach the mechanical drive the merit, then the further showing hydraulic transmission plan arrangement, obtains the entire wrap equipment on vehicle scheme of arrangement through the analogy, but also absorbs a present more advanced position to correct an error the system.

Uses the literature and comparative analysis of high-speed camera and so on, adopted Germany SIMI-motion video analysis system to analyze the technical characteristics of hammer throw athletes between the champion Miankewa and bronze medal Zhang Wenxiu in 29th Olympic Games, and to find the difference between these two athletes. The recommendations for future training of Zhang Wenxiu were provided in the end of this paper.

运用文献资料、高速摄像和对比分析等方法，采用德国SIMI- moTion 录像解析系统对获得第29 界奥运会女子链球冠军的米安科娃和季军的张文秀的旋转阶段各时相的技术特征进行运动学解析，旨在找出张文秀与米安科娃在旋转技术上的差距，并提出有针对性的建议，为张文秀今后的训练提供理论依据，为提高我国链球运动的水平提供参考。
