角锥

Small diameter and little awl corner hydrocyclone has better separate, lower work capacity, large pressure drop and diffluence ratio.

小直径小锥角水力旋流器分离粒度小、处理量小、压降大、分流比大；

2According to requirement of suppressing stray light in two-mirror system, vertex coordinate formulas of inner baffle are deduced based on geometrograph in the case of certain obscuration, viewing field and vignetting. In order to reduce the obscuration, conical baffle of secondary mirror is ameliorated into a shutter one. Outer baffle is designed when angle of stray light suppressing is foregone and the vanes are designed in C-language program. Finally, the same-height vanes in drawtube between primary and secondary mirrors are designed for further suppressing the stray light in two-mirror system.

给出双反射系统杂散光消除设计的具体要求，结合作图法，推导出考虑视场大小及初始中心遮光比确定时，主次镜内遮光罩顶点坐标公式；讨论考虑渐晕时主次镜内遮光罩的设计；为了减小初始中心遮光比，将次镜锥状遮光罩改进为百叶窗式结构；设计在杂散光源抑制角已知时的外遮光罩，并利用C语言实现程序化设计其挡光环的方法；设计主、次镜间镜筒内壁上等高挡光环，进一步抑制双反射系统的杂散光。

运用有限元法分析了不同入口锥角的陶瓷喷砂嘴冲蚀过程中的应力状态。

The influence of die entrance angle on extrusion process of AA1100 Profile Aluminium has been studied using finite volume method.

本文采用有限体积数值模拟方法，针对模具锥角对AAll00铝材挤压过程的影响规律进行研究，采取从30。

Benefit of this modified shape is that the expansion around the first corner reduces the initial pressure coefficient on the frustum to low values.

这个改进的外型的优点是绕第一角点的膨胀会把截锥上的初始压力系数减少到很低的值。

The results indicate that the cone half angle increases with liquid pressure. The stripped half wavelength liquid fragment seems to break into a series of drops immediately and no obvious contraction from liquid fragment to ligament is seen.

研究结果表明，液膜半锥角随着液压的增加而增加，半波长的液膜段剥落后几乎立即破碎成液滴，看不到明显的液膜段收缩成液丝的过程。

It is shown that maximum temperature value of the field's will rise while the Mach number increases. After the Mach number exceeds one, a clear bowshock is obtained in the simulation result, and the Mach angle decreases along with the Mach number. Those are consistent with theoretical results. While the Mach number is 3.5, even the radome inside is adiabatic, the maximum temperature is below 1000K. So the CVD diamond thick film radome can meet practical requirement of flight at 3.5 Mach number.

研究发现，随着马赫数的增加，温度场中最大温度值也随之增大；在马赫数大于1时，会产生明显的弓形激波，且激波的锥角随马赫数增加而减小，这与理论结果相一致；当马赫数为3.5时，即使在头罩内壁绝热条件下，温度场中最高温度值也在1000K以下，表明CVD金刚石厚膜可以满足Ma=3.5的实际飞行要求。

When used in the case of oblique incidence or large cone angle incidence, this filter reduces shift of central wavelength significantly while still maintaining its filter characteristics.

这种滤波器使用于斜入射光和大光锥角照明时，不仅中心波长移动显著减少，而且特性仍能保持良好。

Long gradually expands the tube regarding the conventional structure right circular cone, looked from the mobile angle, when design catalytic converter, in principle should use the small cone angle divergent tube.

2对于常规结构的直圆锥长渐扩管，从流动的角度来看，设计催化转化器时，原则上应采用小锥角扩张管。

The figure of silicon tips etched in this novel etching solution is rocket tips on right rectangular pyramid rather than unsymmetrical eight sided pyramid etched in other etching solution.

更为重要的是该腐蚀液腐蚀的硅尖异于常规的不对称八棱锥，而是一种半锥角很小的"火箭尖"形状，因此可望获得更好的扫描特性和隧道效应。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
