Projectors and monitoring hydrophones are placed n a chamber along its length. The projectors are driven By the required drives that are calculated aceording to a measured transfer matrix, and amplitude, frequency and incident of the predicted plane wave. Then the acoustic pressure field distribution which is equivalent to the predicted plane wave of any incidence is set up in the chamber. A prototype calilbration system has been developed.

在管中沿管轴方向布置一系列发射换能器和监测水听器，根据实测得到的传递函数矩阵和所要模拟的平而波频率、幅度和入射角计算得到一组发射换能器驱动信号的幅度和相位，然后以此信号激励每个发射换能器，就能在管中形成一个等同于任意角度入射的自由场平面波声场的声压分布。

API specification states that the yield strength of body of oil line pipe is evaluated by flated sample cut from pipe.

API标准规定，采用管体取样压平试样的屈服强度，表征输油管管体屈服强度。

For UOE tube with low springback stress,the Bauschinger Effect makes the yierld strength of flated specimen be lower than that of UOE tube body which received expanding process.In this case,Using plated sample as the body representation is safe and conservative.

对UOE管，由于其弹复应力低，包申格效应使压平试样的屈服强度低于经强力扩径强化的管体屈服强度，因而这种表征是偏于安全的。

Then it retracts back again to the base due to the electrolyte concentration increasing or water penetrating.

第二类myelin的形成是由于心磷脂层状膜在溶胀过程中，由于膜间压过大造成了平面膜向管状膜的转变，是热力学驱动的生长。

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。
