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。

To distinctly find out the relationship between the rigidity of tablet and the ultrasonic speed,laser is emitted to the tablet and then we measure the speed of reflected surface acoustic wave and analyse the experimental data,finally get the tablet rigidity-wave speed curve.

为了清楚地了解片剂的硬度与超声波速度之间的关系，利用激光照射到片剂上，通过测定出反射的声表面波速度，且对实验数据进行分析，从而得出片剂的硬度与声表面波速度之间的关系曲线。

Cavity flows both with and without sound excitation are studied by solving the 2 D time dependent Reynolds averaged Navier Stokes equations using explicit predictor corrector difference algorithm of Mac Cormack.

采用显式MacCorma－ck二步预估校正有限差分格式，求解二维雷诺平均非定常Navier－Stokes方程；并用Cebeci－Smith代数紊流模型作适当修正来模拟紊流效应，对有、无前缘声激励两种情况的空腔流场作了数值模拟，计算的振荡频率及振荡幅值都与实验结果基本符合，并且较好地模拟出了声激励对流场的影响。

The men was very huffy, and some of them wanted to hang Jim for an example to all the other niggers around there, so they wouldn't be trying to run away like Jim done, and making such a raft of trouble, and keeping a whole family scared most to death for days and nights.

这样一说，大伙儿冷静了一些，因为那些急着要绞死那做了错事的黑奴的人，往往是最不愿意为了出过气拿出赔偿金的。尽管如此，他们还是恶狠狠地咒骂杰姆，还时不时地给他一个巴掌。不过杰姆决不吭一声。

This time, my heart throbbing, carefully stretching far incense In the past, finally lit the fuse,"Bang, wind," is heard, fireworks emitting a spark jump out far away.

这时的我心怦怦直跳，小心翼翼地把香远远地伸过去，好不容易点着了导火线，只听"嗖"的一声，烟花冒出了火花，蹿出老远。

Quickly the trickle becomes a flood of glistening linseed oil as the beam sinks earthwards, taut and protesting, its creaks blending with the squeaking and rumbling of the grinding-wheels and the occasional grunts and sighs of the camels.

随着大梁越压越低，缆索越绷越紧，大梁的嘎吱声，石磙的辘辘声，以及骆驼不时发出的咕噜咕噜的呼吸声和叹息声响成一片，榨出的油也很快地由涓滴细流变成了一股晶莹发亮、奔腾不止的洪流。

After plastering, Hai Xi Xi jumped down from the Kang, and said anything when he found the flamy blaze in the chamber of the stove run into the smoking path, and there was so much water vapor vaporized from all of the Kang, the brown wet mud gradually became white.

海喜喜泥完后跳下炕，看着灶膛里熊熊的烈火一个劲儿地往烟道口窜去，而满炕都冉冉地蒸发出水汽，褐色的湿泥渐渐地变白，也不作声了。

It mingled with her own biscuity odor, and my senses were suddenly filled to the brim; a sudden commotion in a nearby bush prevented them from overflowing — and as we drew away from each other, and with aching veins attended to what was probably a prowling cat, there came from the house her mother's voice calling her, with a rising frantic note — and Dr.

那种清甜的麝香味，混合着她饼干般的汗香，让我的感官突然达到极限；不过树林边突然的骚动使它们没有溢出来：当我们心痛地迅速分开，想着估计是一只夜游的野猫时，她的屋里传来她母亲叫她的声音，一声比一声高；同时，库伯医生也蹒跚的走出屋子，来到花园。

But the man became a pigeon son to not only fly, process finally flew back for fly of two dayses, fly to village of time he saw him a beloved woman, just ratio past distressed a lot of, he diligently want to fly to chemisette nearby, but more near more see not pure chemisette face, be he fly to chemisette front of, woman disappear, at he at present but is a tree, on the leaf that is from this tree branch fall in the every drop Ta water bead of the Ta, elephant that spring the continuing light drizzle of the sort, water bead dozen wet snow-white pigeon son, but the pigeon son still keep strongly and without intermission looking for his beloved woman, see that mythic fungus grass will floating about, pigeon son any further have no some energy, he fall on the tree branch of this tree and surround on all sides, suddenly he shout loudly 1, a thing with red Xing drop down from the tree, at it fall in of place, long a small tree, but the pigeon son so and forever stop at tree up, expect of look in the eyes' being clear be long separation waiting for, looking for of lover.

而男人变成了一只鸽子不止的飞，经过了二天的飞翔终于飞回来了，飞到村口的时候他看到了他心爱的女人，只是比以前憔悴了很多，他努力地想飞到女人的身边，可是越近越看不清女人的脸，当他飞到女人的跟前时，女人消失了，在他眼前却是一颗树，从这颗树枝的树叶上落下了滴滴嗒嗒的水珠，就象那春季般的绵绵细雨，水珠打湿了雪白的鸽子，而鸽子还是拼命地不停地寻找着他心爱的女人，眼看着那颗灵芝草就要凋零，鸽子再也没有一点儿力气，他落在这颗树的树枝上，环绕着四周，忽然他大叫一声，一颗腥红的东西从树上掉下来，在它落下的地方，长出了一颗小树，而鸽子就那么永远地停在了树上，期盼的眼神分明在等待着、寻找着久别的恋人。

But suddenly, as we struggled round a bend,there would be a glimpse of rush walls, of peaked grass roofs, a burst of yells, a whirl of black limbs, a mass of hands clapping, of feet stamping, of bodies swaying, of eyes rolling, under the droop of heavy and motionless foliage.

然而，当我们奋力转过河弯时，会突然瞥见那静静垂着的浓荫下拥挤的墙垛，尖尖的草屋顶，许多黑色的肢体在旋转，许多眼睛在骨碌碌转，还会听到爆发出的呼喊声，许多手的拍击声，许多脚的跺地声。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
