The fatigue is analyzed for the SENT specimen of TA6V titanium alloy at different stress ratio and on different stress level by the general finite element analysis software ANSYS. The dangerous fatigue location is predicted by the nodal stress Y-direction of the hemicycle notch for TA6V titanium alloy SENT specimen. Based on the local stress-strain method and the material S-N graph, the nominal stress-strain of the specimen is converted to the local stress-strain of the dangerous location by the elastic and plastic finite element analysis, thus the fatigue life is estimated by Miner fatigue damage accumulation theory and compared with the fatigue test of small crack growth.

借助大型通用有限元分析软件ANSYS对TA6V钛合金SENT试样在不同应力比和不同应力水平下进行疲劳分析，根据SENT试样缺口处的应力状态分布预测疲劳危险部位，采用局部应力应变法，结合材料循环的S-N曲线，通过弹塑性有限元法将构件上的名义应力谱转换成危险部位的局部应力应变谱，从而根据危险部位的局部应力应变历程采用Miner累积损伤理论对构件的疲劳寿命进行估算，并与疲劳小裂纹试验数据进行比较分析。

The graphic accelerator which differs from previous only in terms of lower frequencies, Radeon x1950 GT, will fall in price on 10 Euro-, to 159- TI (we are talking hereabout the version with interface PCI express).

它不同于以往的图形加速器仅在较低频率，真实感x1950燃气轮机、12月10欧元的价格将下降、至159钛(我们现在所谈的同版本的PCI介面快递)。

When the mesostructure is basically formed, the pH value of the reaction system is adjusted to 7-8 and then the hydrothermal crystallization is prolonged for some time to obtain heteroatom-incorporated mesoporous silica. The aim of adjusting pH value to near neutral is to change heteroatom species from the cationic to oxo form and therefore can enter the mesoframework through condensation with silanol groups in the wall.

该方法主要的特点是：操作简单（以调节体系pH值代替繁琐的后处理过程），效率高（可以得到Si/Al=5且铝物种全部处于四配位的骨架位置的Al-SBA-15），不破坏产物有序结构（产品具有高度有序的介孔结构），具有普遍性（适用于多种杂原子的掺杂如铝、钛、钒）。

The results of transmission electron microscopy showed that the grain of strontium titanate powder prepared was spherical and the grain sizes distribution were homogeneous.

通过TEM分析可以看出，制备的钛酸锶粉体材料的颗粒为球形，并且颗粒大小均匀。

We produce the activity sodium humate containing elemental selenium, titanium, thorium, strontium, rare earth and other active substances, which is the other similar products do not have.

我们生产的活性腐植酸钠含有元素硒、钛、钍、锶、稀土等活性物质，这是一般同类产品所不具备的。

These results indicated that a well structured anatase TiO2 was obtained by impregnation method under 500℃. Flow rate, in the activity test, could be neglected for mass transfer effects. As a matter of fact, relative humidity played the most important role in this reaction. The highest removal efficiency was obtained while relative humidify of 56.8%. Water molecules are sources of ; however, excessive water molecules could inhibit reactions by competing activity sites with organic containments. In the regeneration test, photocatalyst could be reactivated through a running water vapor with UV light illumination process.

研究结果指出，以含浸法制备之触媒於500℃锻烧下，具有良好的锐钛矿晶体结构；另外在活性测试的部份，流量的增加，污染物之去除效果不受影响，所以本实验选择以200ml/min之流量可忽略质传影响；湿度扮演重要的角色，当RH=56.8％时去除效率最高，主要因水气是产生氢氧自由基的主要来源，但是过多之水气可能与有机物竞争触媒表面上的活性位置，因而抑制反应的进行；初使浓度对去除率之影响中得知，初使浓度的高低不会影响触媒对有机物的催化能力，实验使用之触媒量适合催化200~250ppm之有机物，可藉由增加触媒量提高对有机物之催化能力；此外再生的测试，触媒可经由连续曝水及紫外光的照射，使触媒恢复原有的活性，可再次利用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
