This paper presents the results of measured wall pressure fluctuations and the characteristic parameters of shock motion in the upstream influence region of separation shock induced by unswept and swept compression ramps,blunt fins with a semicylindrical leading edge under the condition of freestream Mach number of 7.

This paper presents the separation shock motion features induced by a hemicylindrically blunted fin in a hypersonic turbulent flow.

The air compressed mainly by the moving shock wave.

The influence of moving shock wave on the ratio of total enthalpy, total pressure and the turning angle of flow passing through shock wave are given and analyzed, The calculated results show obviously difference from those under stationary shock wave condition.

The tilt movement of the Ryukyu island-arc system toward the ocean trench and the waving movement of the mantle stream in the island-arc-back-arc area are the power source of the movement of the Okinawa Trough.

But the sports stress was caused by high intensity exercise and apoptosis of the cells was induced by factors of the stress,such as free radical,hypoxia,blood deficiency,etc.

The Effects of Exercise Stress on Hypothalamic-Pulsatile System of HPG Axis and its Adaptation;

Progress of stress protein in the research of exercise stress;

The influence of exercise training on exercise stress in patients with essential hypertension;

In order to meet testing requirements of MEMS periodic motion,a synchronous control system of stroboscopic imaging and motion excitation based on FPGA is built for the excitation of periodic motion and the image acquisition in the course of the high-speed motion of microstructures.
