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。

Explanation: Put a satellite in a circular orbit about 42,000 kilometers from the center of the Earth (36,000 kilometers or so above the surface) and it will orbit once in 24 hours.

解释：一旦在24小时中，把一卫星放在一离中心大约42，000 kilometers地球(36，000 kilometers左右在表面)和它之上的圆的轨道里就将绕轨道运行。

Mathematics: Understands and applies basic and advanced properties of the concepts of geometry; Use the Pythagorean theorem and its converse and properties of special right triangles to solve mathematical and real-world problems; Understands the basic concepts of right triangle trigonometry (e.g., basic trigonometric ratios such as sine, cosine, and tangent); Uses trigonometric ratio methods to solve mathematical and real-world problems (e.g., determination of the angle of depression between two markers on a contour map with different elevations); Uses properties of and relationships among figures to solve mathematical and real-world problems e.g., uses the property that the sum of the angles in a quadrilateral is equal to 360 degrees to square up the frame for a building; uses understanding of arc, chord, tangents, and properties of circles to determine the radius given a circular edge of a circle without the center

Enceladus' orbit around Saturn is eccentric," Mitchell says. It's just enough off of circular that the effect of gravity on the moon is different from one point to another, and different from the planet's other moons."

Enceladus的公转轨道是离心圆，"Mitchell说，"是围绕一个中心绕圈转动，所以在圈的每一个点上的引力是不同的。
