必要时

When high-strength sheet metal straightening,it will have a Turtle phenomenon,its process control model is obviously inadequate hydraulic pressing,the Shaft of straightening machine Often broken and the work of roller bearings damage Frequently.so it is necessary for the fuel tank pressure,displacement and the roll rotation of the motor current,torque drive signal for analysis.

当矫直高强度薄板时，会产生龟背现象，其工艺控制模型中液压压下明显不足和矫直机传动轴经常断，工作辊轴承经常损坏问题，于是很必要对液压缸压力，位移和各辊的电动机转数，电流，传动扭矩信号进行分析。

There are two kinds of information privacy protection mode-the property rights-based protected mode and moral rights-based protected mode. It can be concluded that both of the two models are not able to provide a complete and effective information privacy protection by combining the personality with interests of property. So, when we choose or establish an information privacy protection mode, there is no need to engage in a "quasi-religious disputes" to solve the personal information is a civil liberty or a property interest, it is a wise choice to open a new path, applying modified trade secrecy default rules to information privacy protection.

本文重点分析了两种信息隐私权保护模式，即以财产权为基础的保护模式和以道德权利为基础的保护模式，认为两种保护模式都不能将信息隐私中所蕴含的人格利益和财产利益有机的统一起来对信息隐私权提供完整有效的保护，我们在选择或者建立信息隐私权保护模式时，没有必要卷入一场&准宗教争议&去解决个人对其信息隐私所享有的权利或者利益究竟是一项公民自由还是一种财产利益，而更加明智的选择是另辟蹊径，将商业秘密不履行规则修正后适用于信息隐私权保护。

The results show that, the Fick's second law based on corrosion environment should be presented; the linear isotherm of chloride binding is appropriate in concrete structures; the amounts of bound chloride in tide range area and air environment is 0.11~0.37 times of free chloride; the diffusion coefficient is 1/3 to the concrete without RAM and the effect is the best when the RAM ratio is about 15%.

研究表明：Fick第二定律仍需进一步改善，有必要根据不同侵蚀环境建立不同的侵蚀模型；用线性结合理论描述实际混凝土结构中的氯离子结合基本适用；潮差区及以空气中氯离子侵蚀为主的混凝土结构，结合氯离子占自由氯离子的相对值大致在0.11～0.37之间；掺加海水耐蚀剂混凝土的氯离子扩散系数大致可降为原来的1/3；海水耐蚀剂含量在15%左右时其提高混凝土抗氯离子渗透性能的效果最明显。

The application of information technology has become the crucial method for the business companies to increase their competition ability in the rapid-changing modern society. The past studies have shown that the companies' application of information technology may cause the employee's resistance against the information system. This would lead to the increasing cost, the decreasing ability to change, or even the decreasing of productivity.

中文摘要企业对於资讯科技的应用，已为在迅速变迁的现代社会中，增加竞争力的必要方式，过去的研究发现，企业在实施资讯科技时，会发生员工对於资讯系统的抗拒行为，而导致企业运作的成本增加、弹性减少甚至是减少生产力的现象。

The second-world-war slogan springs to mind in the wake of the volcanic cloud that has disrupted air travel this week.

于是，人们开始重新思考二战时那句标语：&您的旅行真的有必要吗？&

Through the above, we can see that after a lot of line from the telephone switchboard link have caused problems as a phone fault, but the fault is a certain law. users can use the law to judge the fault position. This report will give us the failure to provide the necessary basis, your guide for troubleshooting or simple exclusion of your own fault.

通过上面的介绍，大家可以看出，从电话交换机出线后要经过很多环节，任中一个出现问题都要造成电话故障，但故障是有一定规律的，广大用户在使用时可根据规律判断故障部位，这样在故障报告时能给我们提供必要的依据，从而为您尽快排除故障或指导您自己排除简单故障。

From combining internal force calculation with design detailing, some calculation simplifications and hypotheses are first presented, then a calculation method and corresponding formulas of internal forces for elliptical spiral stairs are derived.

采取计算与构造相结合的方法，进行必要的计算简化和假定，在椭圆形旋转楼梯的内力计算时，把固定坐标变换成动点坐标，推导相应的计算公式。

I start modeling the snail shell, to do this I use a spiral spline and a circular shape inside a sweep NURBS, I activate it and adjust the spiral parameters to get both the necessary turns and the thickness at the beginning and at the end.

我开始建模蜗牛壳，为此我使用螺旋花键和一个圆形形状内打扫的NURBS ，我激活它，并调整螺旋参数，以获得这两个必要的转折和厚度在开始和结束时。

Audio denoising is the pre-step in the audio processing,and wavelet domain denoising has been a main research area.In order to give people a summary knowledge of wavelet domain audio denoising,based on many literatures,this paper attempts to make a survey of wavelet domain audio denoising.First,it introduces wavelet transformation and the characteristics,and gives the optimal selecting and dealing criterion of wavelet domain denoising,the basis wavelet selection.Second,describes five classical methods of audio denoising,for example,threshold,multi-wavelet,wavelet packet,modulus maximum and scale correlation,then introduces their development.Third,introduces a new algorithm based on modulus maximum and scale trading theory.At the end,the future trend of wavelet domain audio denoising is pointed out.
