The following are the expressions for the mean pressure set up at the detection plate and for the time of the signal to progagate from the radiator to the detector:这里是1个公式,省略） where Re is the real part of the expression appearing within the braces, 0 is the density of the medium, vo is the amplitude of the vibrational velocity, c is the speed of sound in the medium, d2 = I +(r/zcos 8, z is the distance between the emitting and receiving plates, B is the angle between the axis of the acoustic channel and the axis of the tube, r = vro/c, v is the flow speed of the fluid, d is the diameter of the pipe, m is the circular frequency, k is the wave number, where a is the radius of the plate (this is taken as the same for the emitting and receiving plates for simplicity, but there is no difficulty in discussing plates differ~mg in radii),,~ is the vibrational frequency of the emitting plate, and The triple sums in the expressions for N~ and N2 may be neglected if the flow speed is low, since the contributions for these become negligible.

以下的表情为代表的压力设置在检测板甲，手持骑枪和时间的信号 progagate从散热器排出到检测器(这里是1个公式、省略)。在什么地方才是真正的出现在背带，表现为0密度的吗当时的媒介的振幅振动速度、c是声音的速度中、d2 =我+ r / z，8、z是距离的发射和接收板、B之间的角度对声信道和轴轴管，r = vro / c，v的流体的流动速率公式，d 管直径的圆频率，m，凯西是波数公式* n，一个是半径的板(这是作为相同的发射和接收吗为了简单，但板板是毫无困难地讨论不同半径)、镁-，~的振动频率的发光，。总结了三倍的表达方式和N2 ~能忽略的流量速度低，因为这些变得微不足道的贡献。

From the beginning of 2005, my company the first in China to enter the copper clad aluminum-magnesium alloy wire of the technology development and product applications.

从2005年始，我公司在国内率先进入到铜包铝镁合金线的技术开发和产品应用。

However, magnesium alloys have poor formability due to the hexagonal close-packed crystal structure.

但是，镁合金大多具有密排六方结构，传统上一直被认为是一种难以塑性变形、压力加工成形性能差的金属材料。

In this paper, after briefly recalling the basics of CPMD method and the development of the CPMD code, firstly a cluster of 10 nodes is set up and the efficiency of parallel computing is studied on it for further computational chemistry study.

我们在自行架设的集群环境上用CPMD方法研究了氧分子在氧化镁(100)表面的吸附过程。

Urea solution, saturated salt water, magnesium sulfate solution and sugar solution were used for floating fluid. Rabbit coccidia oocysts were collected by floating and centrifuging, on which three comparative tests were conducted under same conditions.

利用尿素溶液、饱和食盐水、硫酸镁溶液和砂糖溶液作漂浮液，通过漂浮、离心方法收集兔球虫卵囊，在相同条件下进行3个试验比较。

The third was to compare the effects of the different floating liquids on the growth of the rabbit coccidia oocysts. Magnesium sulfate solution showed the smallest influence rate (4.94%) and saturated salt water (7.47%) had the largest.

其三，不同漂浮液对兔球虫卵囊发育影响作用比较；结果表明硫酸镁溶液影响率最小(4.94%)最大的是饱和食盐水(7.47%)。

The second was to compare the effects of the different floating liquids on the destruction of rabbit coccidia oocysts. The results indicated that magnesium sulfate solution showed the lowest rate of coccidia oocyst destruction at 20 min; saturated salt water had the greatest rate of destruction. The destruction increased with time; in the saturated salt water and urea solution damage or deformation of a few coccidia oocysts at were observed 60 min.

其二，不同漂浮液对兔球虫卵囊破坏作用比较；结果表明20min时硫酸镁溶液对卵囊破坏率最低，破坏率最大的是饱和食盐水，随着时间延长各种破坏作用增大，60min时饱和食盐水和尿素溶液中有极少卵囊破损和卵囊变形现象。

Secondly, before reseeding white clove and cocksfoot firing disposal should be done to the main weed and the dead substance on pasture in June.

18.1 提高牧草生长速率的有效优化调控技术是：第一，7～10月牧草生长旺季适当增加载畜量；第二，6月份对草地主要杂草和死物质进行火烧处理，然后补播白三叶和鸭茅；第三，6月初雨期撒施钙镁磷肥、尿素；第四，实施划区围栏，有效控制放牧面积；第五，每年5—10月刈割杂草；第六，适度减少人工草地中非洲狗尾草和狼尾草的比例或予以清除；第七，在与常年风向垂直的地段建植防护林带。

Because of the lower coercive force and high damage threshold, the crystal is chosen and designed for six period patterns.

由于周期极化掺杂氧化镁的铌酸锂晶体具有较低矫顽场和更高损伤阈值的优点，所以选择了该晶体并在其上设计了6个周期图案。

Magnesium is an essential element in human nutrition; it is the cofactor in enzymes of carbohydrate metabolism and in chlorophyll.

镁是人体营养的一个重要元素，也是在碳水化合物代谢中的和叶绿素中的辅助因子。

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。
