捩转

It signifies that the solutions are periodic or approximately periodic in some specified range of Reynold numbers and that a very complex transition occures by a few period doublings following Feigenbaum's route to chaos.

结果表明在一定的雷诺数范围内解是周期或拟周期的，并且有一个复杂的倍周期分叉途径向混沌转捩。

A new ignition system is applied to pulse detonation engine, which is a flame jet ignition system, to enhance a deflagration to detonation transition time and length.

为了缩短爆燃向爆震转捩的时间和距离，该文将一种新型点火系统－火焰喷射点火系统应用于脉冲爆震发动机。

The obtained results were compared to data of testing the same model in a hot-shot wind-tunnel IT-302M at M_∞≈6 and 8,τ=100～120ms,Re_(1∞)=(1.3～1.8)×10~6,with boundary layer tripping on the surfaces of the inlet ramp and side compression wedges.

所获数据与同一模型在热射流风洞IT-302M实验马赫数M∞≈6，8，运行时间τ=100~120ms，雷诺数范围Re1∞=(1.3~1.8×106，进气道压缩面和侧压缩面进行了边界层转捩。

The properties of the shear layers are analyzed in the states of purely laminar, fully turbulent and laminar+transition+turbulent using the Thwaites Integral and Head Integral methods.

文中采用的数值求解过程为：首先求解给定翼型的位流速度分布，在此基础上采用Thwaites积分法和Head积分法，分别计算纯层流、纯湍流以及层流+转捩+湍流这三种流态的边界层，分析三种流态的边界层特性。

In vortex ring zone, streamwise vorticity and vortex ring wrap together and interact each other. This interaction leads to the breaking of vortex ring.

在涡环区，流向涡和涡环相互缠绕，相互作用，导致涡环的空间失稳及最终破碎，涡环的破碎标志射流开始转捩进入湍流阶段。

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。
