The results show that boundary layer suction can restrain the corner separated flow, weaken the intensity and scale of passage vortex, and improve the cascade flow capacity.

结果表明，采用吸力面两端吸气对抑制角区分离流动、减弱通道涡强度和尺度、提高叶栅内流动性能的效果要优于其它两种方式，积聚在角区的低能流体由于较大的吸气量而被大量吸除是性能改善的关键。

By using a shooting method, the strongly nonlinear ordinary differential equations with two-point boundary conditions were solved and numerical solutions for thermal post-buckling and bending deformation of sandwich Timoshenko beam with pinned-pinned ends and subjected to transversely non-uniform temperature rising were obtained.

Therefore a GD sand-screening pipe is developed, which is helpful to the environment protection. This new sand-screening pipe consists of center pipe, sand filter and guide shoe. The center pipe is machined from 64mm tubing, and the sand filter is made from silica sand, cement, additive.

这种环保型滤砂管由中心管、滤砂器及引鞋组成，中心管采用 6 4mm油管加工而成，两端为特种 6 4mm平式油管螺纹，管体上每米均匀分布 72个直径 10mm孔眼；滤砂器是根据不同技术标准筛选不同粒度的石英砂、油井水泥、添加剂和水按配比加工压制的。

The fuse pipe is the main part of fuse,it is made by installing the fuse wire in the porcelain pipe,filling the quartz sand in the porcelain pipe and sealing to-ends of pipe.

熔断管是熔断器的主要部件，它是由熔丝装在瓷管中，并在瓷管中充填石英砂，两端密封而成。

They were raised on small, poor ranches in opposite corners of the state, Jack Twist in Lightning Flat up on the Montana border, Ennis del Mar from around Sage, near the Utah line, both high school dropout country boys with no prospects, brought up to hard work and privation, both rough-mannered, rough-spoken

他们生长在贫苦的小农场上，在怀俄明州的对角线两端--杰克崔斯特住在蒙大拿州边界的闪电平原镇，恩尼司岱玛老家则在犹他州边界附近的圣吉，两人皆为高中中辍生，是毫无前途的乡下男孩，长大面对的是苦工与穷困。

A double sloping roof with a ridge and gables at each end.

上面一个屋脊、两端有山形墙的屋顶。

As we know, support at the both straight edge of ACMR is a elastic support between the hinged support and fixed support, and its stiffness is variational. So the relation between support stiffness and load-carrying capability of ACMR is worth to be studied. Meanwhile, arched roof is generally set on beam at the top of pillar.

众所周知，实际工程中波纹拱两端的直边支座处于铰支和固支之间，属一弹性支座，其弹性刚度是变化的，支座刚度与波纹拱结构受力性能及稳定承载力之间的关系是一个非常值得研究的课题。

The present invention relates to a kind of tunable plasma resonant cavity for PCVD optical fiber perform rod processing machine. The tunable plasma resonant cavity includes cylindrical resonant cavity casing and cut-off waveguides set on two ends of the casing, and features the tuning piston, which is set on one end of the cylindrical resonant cavity and has middle part with through hole and back end stretched beyond the casing.

本发明涉及一种用于PCVD光纤预制棒加工机床的可调谐等离子体谐振腔，包括有圆柱型谐振腔壳体，在圆柱型谐振腔壳体的两端设置截止波导，其不同之处在于在圆柱型谐振腔腔体的一端安设调谐活塞，调谐活塞的中部开设通孔，后端延伸至圆柱型谐振腔壳体外端。

Additional efficiencies are achieved through maintaining the voltage ripple across the fly capacitor and/or the load capacitor.

通过保持快速电容器和/或负载电容器两端的电压波动来获得额外的效率。

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