Finally, the parameters, such as density, thickness of porous media, thickness of steel of each material in air and porosity, pore size, thickness of porous materials, thickness of steel and incident angles in water were investigated and also the influence on the sound absorption and insulation were discussed.

最后，分别就空气中以及水中的材料参数，分门别类的观察其对吸音与隔音的影响。在空气中所讨论的参数，有多孔材密度、多孔材厚度、钢材厚度。在水中所讨论的参数，有多孔材孔隙率、孔隙尺寸、多孔材厚度、钢材厚度、声波入射角度。

Use symmetrical cylindrical gear,reduction gear and spiral load brakes to achieve an unique combination of high mechanical efficiency,lower effect on hand chain and brake reliability.

主要零件均采用优质钢材制造，起重链条选用合金钢材，用引进的先进设备制造。

Generally in accordance with the strength of steel grades in the selection of the appropriate electrodes, but also need to weld steel, base metal composition of the transition, welded structural dimensions.

一般依钢材的强度等级来选用相应的焊条，同时还需要钢材焊接性，母材成份的过渡，焊接结构尺寸。

Based on the experiment and theory analysis, we give out the fatigue reliability curve of these two kinds of materials to provide bases for engineering.

通过上述试验研究与理论分析，给出 WH530和WH610D2两种钢材的疲劳性能参数，并给出这两种钢材的疲劳可靠性曲线，为工程应用提供依据。

Apply on properly prepared steel, treated galvanised steel / aluminium, or others as recommended.

施工于适当处理的钢材、电镀处理的钢材和铝材，或其他推荐底材上。

It improves the machinability of steels because of brittlement of grain boundaries resulting from the tin segregating on the grain boundaries of the steels.

锡可有效改善钢材的易切削性能，原因是在切削温度范围内富集在晶界的锡使钢材的塑性降低。

Steel, which are used are directly imported from Japan a steel, with ion nitriding furnace, high-frequency heat treatment and other specialized manufacturing equipment, the company has manufactured more than 25 years of technical superiority, so that our products will be well received around the world affirmed much further and specify the use of steel produced by the Product.

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。
