On the tailward side of the terminator plane, the anisotropy of the fast magnetosonic wave speed dominates, so the cross section of the bow shock is wider in the direction perpendicular to the IMF.

对于终端面尾侧，快磁声波速度的各向异性起主导作用，弓激波截线沿IMF垂直方向的宽度大于平行方向。

Firstly, studies for hypersonic inlets are reviewed, including issues related to interaction between boundary and shock wave in hypersonic inlet, unstarting/restarting phenomena, isolator, boundary bleeding for hypersonic inlet, internal/external compression ratio for inlet, inlets with sidewall compression, etc..

The conclusions drawn from the analysis of the compressible turbulence are:(1) Statistical results including the skewness of velocity derivative are in satisfactory agreement with the known results, verified the effectiveness and validness of our schemes for DNS of turbulence.(2) Based on the idea of Samtaney for extracting discontinuities in compressible flows, the shocklets are successfully captured and the shock strength is statistically analyzed.

对贮存的可压缩湍流流场进行分析，得到了如下结论：（1）包括速度导数偏斜因子在内的各阶统计量与已有的计算结果吻合得相当好，证明了本文格式用于湍流DNS的正确性和有效性；（2）采用Samtaney提出的提取流场间断的思想，成功地找出了位于微激波上的点，并对其法向马赫数进行了统计分析。

The Mach number approaches unity at the virial shock, where the accreted gas is heated to the virial temperature.

在维里激波处马赫数接近1，气体在此处被加热至维里温度。

For the first time we parametrize such a flow with two physical constants, namely the specific angular momentum accreted by the black hole j and the energy quantity K.

我们首次应用两个物理常量，即角动量积分常数j和能量参数K给出了含激波的吸积流解对应的参数空间。

After this flow pattern transformed into a flow pattern with thermal chocking at the combustion chamber exit and with a pseudo-shock wave developing in the inlet diffuser.

之后，在燃烧室出口出现热拥塞现象、在进气道扩压段产生伪激波流态。

Time-resolved emission experiments on deflagrating metastable interstitial composites of nano-aluminum trioxide are formed in the detonation shock tube.

在爆炸激波管内采集到了纳米铝粉多隙氧化物的辐射谱，通过对所得光谱的拟合，得出其反应温度约为3100K，误差不足100K。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
