The following are the expressionsfor the mean pressure set up at the detection plate and for the time of the signal toprogagate 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 ofthe medium, vo is the amplitude of the vibrational velocity, c is the speed of sound in themedium, 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 andthe axis of the tube, r = vro/c, v is the flow speed of the fluid, d is thediameter 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 receivingplates for simplicity, but there is no difficulty in discussing plates differ~mg in radii),,~ is the vibrational frequency of the emitting plate, andThe triple sums in the expressions for N~ and N2 may be neglected if the flow speed islow, since the contributions for these become negligible.

以下是表达式平均压力为定于检测板和为信号时间progagate从散热器到探测器：（这里是1个公式，省略）假如再是出现在大括号表达式的实部，0是密度中期，沃是速度的振动幅度，C是健全的速度中，D2中=我+的导向8，z是对之间的距离发射与接收板，B是声之间的通道轴角该管的轴，R =中心内大多分为/荤，v是流体的流动速度，，D是管道直径，m是圆频率，k是波数，的其中一盘是半径（这是为重点，同样的发射与接收为le简单板，但没有讨论板的困难，在半径不同毫克），，是发光板振动频率，和在N的表达式的三重总结和N2可以忽略，如果流速低，因为这些变得微不足道的贡献。

A method of determination of the base circle and offset distance was presented and a designer can ascertain the principal size parameters of disk cams correctly or take them as the original numerical values for design.

主要分析了偏置式推杆盘形凸轮机构的主要尺度参数与所给定运动参数之间的关系，并提出了基圆半径r0 ，偏距e等的取值原则与方法，从而准确无误地确定凸轮的主要参数，或是把此参数作为设计变量的初值。

Twilight reigns over it. We perceive vast fluctuations in that fog, a dizzy mirage, paraphernalia of war almost unknown to-day, pendant colbacks, floating sabre-taches, cross-belts, cartridge-boxes for grenades, hussar dolmans, red boots with a thousand wrinkles, heavy shakos garlanded with torsades, the almost black infantry of Brunswick mingled with the scarlet infantry of England, the English soldiers with great, white circular pads on the slopes of their shoulders for epaulets, the Hanoverian light-horse with their oblong casques of leather, with brass hands red horse-tails, the Scotch with their bare knees plaids, the great white gaiters of our grenadiers; pictures, not strategic lines--what Salvator Rosa requires, not what is suited to the needs of Gribeauval.

com 。黄昏将近，千军万马在暮霭中往复飘荡，那是一种惊心动魄的奇观，当时的军容今日已经不可复见了，红缨帽，飘荡的佩剑，交叉的革带，榴弹包，轻骑兵的盘绦军服，千褶红靴，缨络累累的羽毛冠，一色朱红，肩上有代替肩章的白色大圆环的英国步兵和几乎纯黑的不伦瑞克步兵交相辉映，还有头戴铜箍、红缨、椭圆形皮帽的汉诺威轻骑兵，露着膝头、披着方格衣服的苏格兰兵，我国羽林军的白色长绑腿，这是一幅幅图画，而不是一行行阵线，为萨尔瓦多·罗扎①所需，不为格里德瓦尔②所需。
