The low-dimensional Galerkin method is generalized to solve the flow around arbi-trarily translating circular cylinder.Active control problems of wakes behind circularcylinders are numerically investigated by only small number of modes.The in-line andtransverse oscillation of a circular cylinder with proper frequency produce Karman vor-tex street successfully in some subcritical regime,vhereas the transverse oscillation of acircular cylinder with 1.8 times the natural shedding frequency can effectively suppressthe Karman vortex street at a slightly supercritical Re.

将低维Galerkin方法推广至可以求解任意平移运动圆柱的绕流问题，用较少的模数值研究了圆柱尾迹的主动控制问题，在亚临界Re数下圆柱以适当的频率沿流向和横向振动均成功地激发出Karman涡街；而在略高于临界Re数下圆柱以1.8倍自然脱涡频率沿横向振动明显地抑制了Karman涡街；再现了超临界Re数横向及流向振动圆柱绕流的频率锁定等复杂非线性现象。

The results show that when Re is lower, the f is in rough agreement with Hagen-Poiseuille solution, however, Nu is slightly higher than Hausen solution. When Re reaches at 800, begins to depart from Hagen-Poiseuille solution, and Nu begins to increase quickly, which is due to earlier transition from laminar flow to turbulent flow.

实验结果表明，在低Re下，微管内部的值与Hagen-Po1Seuille解基本一致，但微钢管内部的Nu要略高于Hausen的解；当Re达到800左右时，内径为168μm的管内部的值已开始偏离Hagen-Poiseuille、解，Nu急速上升并形成拐点，这是由于流动发生转换导致的。

A test model of four co-rotating disks was developed as the simplified version of a typical internal cooling system of a gas turbine compressor. The investigation was on the distribution of local heat transfer coefficient and the averaged nusselt number of the downstream main disk. Experimental analysis may lead to following conclusions: the distribution is not of monotony and multi-peaks were found along the disk surface,Nu increases with the decrease of the rotational reynold number Re(subscript w,Nu increases with the axial reynold number and the grasholf number.

针对航空发动机多级压气机盘腔的冷却问题，对具有轴向通流的三腔模型进行了系统的研究，通过对局部换热特性与平均换热特性的分析，可以表征旋转盘的热应力水平和相对冷却效果，结果表明表征旋转盘热应力水平的局部换热特性在旋转盘的半径上呈多峰分布，表征相对冷却效果的平均换热特性与旋转雷诺数Re、进气雷诺数Re以及格拉晓夫数Gr有关，当Re及Gr增加时，平均努塞尔数Nu随之增加，而Re的增加使之减小。

When this flag has been specified, whitespace within the RE string is ignored, except when the whitespace is in a character class or preceded by an unescaped backslash; this lets you organize and indent the RE more clearly.

当该标志被指定时，在 RE 字符串中的空白符被忽略，除非该空白符在字符类中或在反斜杠之后；这可以让你更清晰地组织和缩进 RE。

In addition, our works also indicate that MC-ICPMS technique shows a good potential on Re-Os isotopic measurement. 2. A new method for the determination of low Re-Os abundances and ~(187)Os/~(188)Os in a natural rock sample by MC-ICP-MS has been established in our laboratory. Rock samples were digested in inverse aqua regia in sealed Carius tube for 24 hours at 230°C, then Os was separated from the matrix by CCl_4 solvent extraction, and further purification by microdistillation.

The picrites have low Re and high Os concentrations, which are probably controlled by the degree of partial melting and crystallization fractionation. The low Re ,Yb and Re/Os ratios of the picritic lavas support models of high degree partial melting with residual garnet in their mantle source during the early stages of partial melting, and without residual sulphide.

木里地区苦橄岩具有低的Re含量和高的Os含量，Re和Os的含量受到熔融程度和结晶分异的控制，低的Re和Os的含量和Re／Os，以及高的Os含量支持高程度的地幔熔融导致熔体中的硫不饱和，同时源区可能有石榴子石残留。

The larger the atomic volume construction,the higher the stability of intermediate phase.There exist 4 eutectic systems with 9 eutectic reactions in Au-RE systems.A criterion exists between the reduced eutectic temperatureand the atomic radiiof RE metals:the Teu/TA values dedine linearly with the increase of rR Value and keep essentially a constant when rRE values are larger than 0.175nm (namely the atomic size differences between RE and Au are larger than 21%).

Au-RE系中存在4个共晶系9种共晶反应，简约共晶温度与RE原子尺寸之间存在一个判据：简约共晶温度随RE原子半径增大呈线性下降，但当RE原子半径达到约0.175nm(即与Au相对尺寸差21％)时，更大原子尺寸差不再影响液相线和共晶温度下降，简约共晶温度保持常数。
