The results showed the maximum cyclic stress of CFRP bar should be under 70 percent of ultimate tensile stress; when the maximum cyclic stress decrease 5 percent of ultimate tensile stress, the fatigue life of CFRP bars increase generally 10 times; with the decrease of cyclic ratios, the fatigue life of CFRP bars decrease heavily; for the brittleness, CFRP bar should possess a higher reserve of strength, the margin of safety against failure is a necessity; according to experimental cyclic stress-fatigue life curve, the fatigue behavior of CFRP bar is much better than the fatigue behavior of Q235 steel.

将纤维复合材料用于土木工程结构的研究成果，已应用于实际工程【2j_国外对CFRP筋的一些短期性能以及CFRP筋构件的粘结性能、CFRP加筋混凝土结构的抗弯性能等都做了大量的研究，但对其长国家自然科学基金50278029，50538020和交通部西部交通科技200l431882021资助项目。2OO6年2月13日收到初稿；2006年9月4日收到修改稿。本文联系人：欧进萍，院士期性能如疲劳性能的研究还不够

Adelomorphic bar code can achieve without damaging the overall packaging decoration, without prejudice to the purpose of the bar code characters the same invisible bar code adelomorphic in the future, it is difficult to General counterfeits by turning its anti-false well, and the business card printing and membership card when making color does not exist.

隐形条码能达到既不破坏包装装潢整体效果，也不影响条码特性的目的，同样隐形条码隐形以后，一般制假者难以仿制，其防伪效果很好，并且在制卡和会员卡制作时不存在套色问题。

The bar code image recognition program coded by VC++6.0 is compared with the experimently real-time processing system, and the results show mat the processing speed of the latter is very greater than the speed of the front Studies in the thesis promote the automatic identification of bar code image and its practicalization and present some ideas of how to improve the bar code image processing system based on DSP.

If there is joint on the back, in the lower right or fill a 20% discount after it has been causing wrinkles without distortion; vacuum packaging vacuum after the contents of the packin mouldedround radiofrequent nonanatomical tridimension on the surface, shape, surface roughness, would create a bar code reading of deformation cannot, therefore, be appropriate for the vacuum packing inner bag direct business card printing and membership card to make a bar code, you can increase the packin business card printing outside and membership card to make a bar code, and other graphics and text.

如背面中央有接缝，则印在右下方或印在填充后不起皱折、不变形处；真空包装抽真空后包装袋紧贴在内容物表面，呈不规则立体形状，表面不平整，会造成条形码变形不能识读，因此真空包装内袋不宜直接制卡和会员卡制作条形码，可增加一个外包装袋制卡和会员卡制作条形码及其他图文。

Refer to the impacting-echo technology, we impacted the apex of the steel bar and incepted the reflecting stress \\ave through the resonator that fixed on the apex of the steel bar, and the value of the consolidating wave speed was calculated based on the timeof stress wave transmitted and the length of the steel bar, so, identifying the reflecting signal is the key of the consolidating wave speed method.

借鉴于冲击回波技术，固结波速的测定方法是在钢筋测杆的出露端施加瞬态冲击载荷，由安设在测杆顶端的传感器接收反射应力波信号，根据应力波的走时和测杆的长度折算固结波速的大小，因此反射信号的识别是固结波速法检测混凝土强度的技术关键。

In this paper, some problems such as the length of the anchor bar, velocity of the anchor bar and the quality evaluation of the anchor bar are also discussed.

对锚杆检测工作中遇到的锚杆长度、杆体速度和锚杆质量分类等问题做初步探讨。

As to the mate lag problems in loom beat up mechanism,comparing traditional four bar linkages with quick return four bar linkages beat up mechanism,the latter can solve the lag problems effectively.A CAD method of designing the quickreturn four bar linkages beat up mechanism is pointed out,and the design mathematics model and the kinematic analysis model are also presented.

针对现有织机打纬机构和开口机构在运动配合上存在的滞后问题，比较了传统的四连杆打纬和具有急回特性的四连杆打纬机构，基于后者能有效地改善配合上的滞后问题，提出了精确设计具有急回特性的四连杆打纬机构的CAD方法，给出了设计的数学模型、机构运动分析的数学模型。

The Internet bar cooperates, cooperate with each Internet bar, pay a few fee, install the acquiescent and initiative page of the browser for insurance net, look for a 349 domestic Internet bars, the person that this gets online to the Internet bar more than 1, discharge also can be driven a few.

网吧合作，和各网吧合作，支付少量费用，把浏览器的默认起始页都设置为保险网，找个三五十家网吧，这到网吧上网的人一多，流量也会带动一些。

Bar code also known as line of bar code, and bar codes, it is a common commodity label can be said to futuresmarket.

条形码也称线条码和条码，它是一栽常用的商品包装标签，可以说是商品的身份证。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
