In addition, there are round, square, cross, such as plane geometry. 此外,还有圆形、正方形、十字形等几何形状平面。
It makes it fast for a photographer to define the "sweet spot" either in a round shape or a plane and then control how much and of what kind of blur they would like to add. 它使得摄影者能很快地体会到环形或是平面的最佳位置,然后调节加入模糊的量以及模糊效果的类型。
Well then why all the revolution orbits of The9 principal planets round the sun are not parallel to the equator plane of the sun but different obliquities exist. 那么九大行星围绕太阳公转的轨道为什么不都是处在太阳的赤道面平行线上,而是存在着各不相同的倾角?
Research of k-ε Model for Simulating the Heat Transfer of a Round Air Jet Impinging Vertically on Plane Surface 平表面垂直圆射流冷却换热模拟的k-ε模型研究
The limit load formulae of single-edge deeply notched plates with round ends subjected to pure bend moment and tensile load under plane stress condition have been derived. 推导了平面应力条件下单边圆形底部深缺口板条受纯弯曲和拉伸载荷作用的极限载荷公式。
Previously, in "assumed calculation" of extrusion stress of round-head rivet and round hole, it was considered that maximum non-uniform extrusion stress equals approximately to the value obtained from dividing extrusion force by area of diametral plane of round-head rivet or round hole. 在圆钉与圆孔的挤压应力假定计算中,曾认为:以挤压力除以圆孔或圆钉的直径平面的面积所得的挤压应力与理论分析的最大应力大致相等。
In this paper, a self-made geomechanics model material ( MSB) is used for exerting normal load in the direction of actual principal stress on the round sides of the vertical plane stress model of large buried underground power houses. 本试验利用自制的地质力学模型材料(MSB),在窑洞式地下厂房的立式平面应力模型的周边上,按实际主应力方向进行加载。
The distribution of the round jet plane flow field near the spout were measured by using particle image velocimetry ( PIV) at Reynolds number of 6 230 and 10 010.Three different particle sizes of hyaline beads were used as tracer particles. 在水平圆喷口近场处使用了粒子图像测速技术(PIV),对雷诺数分别为62301、0010时的气固两相湍流射流进行测试。
Surface cells were round or ellipse and long axis of cells parallelled cartilage plane. 表面细胞呈圆形或椭圆形,细胞长轴平行于软骨平面。
Round DC Plane Magnetron Sputtering 圆形直流平面磁控溅射
Using a simplified model ( revolution of planets round the sun are uniform circular motions in a plane), the apparent motion of planets relative to the earth is analyzed. 用简化模型(行星在同一平面内绕太阳作匀速圆周运动)分析了行星相对于地球的运动(视运动)。

Then, use model reconstruction methods based on the round table, trapezoidal plane and interpolation to reconstruct branches of tree models. 然后,利用基于圆台、梯形平面和插值的模型重构方法进行树木枝干模型重构。
Milling cutter micro-unit analysis method is introduced, and the corresponding coordinate system is set up at the same time. Micro-unit can be taken as diamond round saw and dish-shaped disk to separately establish cutting force model in each projection plane. 引入了铣刀微元分析方式,同时建立了相应坐标体系,并在各投影平面内将微元作为金刚石圆锯片和碟形铣磨盘分别建立切削力模型。
The result shows that use the high density polyethylene as slowing material and create a cylinder round the proportional counting tube that is placed in the focal plane have an ideal detection efficiency for both the fast and slow neutrons. 研究结果表明:用高密度聚乙烯作为慢化材料,做成圆筒形套在正比计数管上,把计数管放置在焦面上,对快慢中子都具有较理想的探测效率。
The velocity time series of round jets and plane jets are acquired with the hot-wire anemometer. The largest Lyapunov exponents and the random noise of two kinds of jets are computed with the proposed method of chaotic time series. 用热线风速仪采集了圆射流和平面射流的速度时间序列,并用提出的混沌时间序列分析方法计算了两种射流的最大Lyapunov指数和其中包含的随机噪声。
