In order to study the relationships between the anaerobic capacity and maximum lactate value, heart rate (HR) recovery rate and lactic acid (LA) clearance rate, this study measured the blood lactic acid (BLA) concentration, LA clearance rate and HR recovery rate of middle-distance runners, footballers and normal persons after an endeavored 800m running.

The diagnosis value of heart rate recovery after treadmill exercise test to patients with coronary artery disease;

Objective To evaluate the significance of heart rate recovery after treadmill exercise test and its clinical value in the detection of coronary artery disease(CAD).

Heart rate recovery among the 4 groups was compared at 1,2,3,4 and 5 minutes after the test.

The arithmetic flow of the model is also illustrated and then the calcula-ting formulas of administrator-oriented network survivability are proposed,which include the calculation of restoration rate and system state transition matrix.

In this paper,the effect of different heat treatments on the shape memory recovery rate of a TiNiAl alloy was studied and suitable aging temperature and time were given out.

By comparison with the washing effect with the traditional mass water washing method, from view of recovery rate and the retention rate of egg albumin, the wa shing method with spongr rubber ball was better and there was no effects on the membrane pore size.

8at%Ni generates much Ti 3Ni 4 phase, and has the highest recovery rate.

By comparing the effects of the sponge rubber ball washing method and the traditional mass water washing method on recovery ratio and the rejection of egg albumin, the result shows the cleaning effects of the sponge rubber balls to be better and no effects on the membrane pore size.

According to the differences of error concealment between the moving regions and nonmoving regions in a frame, the reasonable order of the nodes in transmission is given, thus ensuring a higher recovery ratio for the moving regions and improving the video robustness.
