First,We use skewness-kurtosis test and Kolmogorov-Smirnov test to study the statistical distribution of return rate of real state indices in the two markets and draw the conclusion that the distribution of return rate deviates normal distribution,then we find out that the distributions of return rate follow power-law distribution through empirical study.

If RMB/USD exchange rate returns are normal distribution, using non-parametric tests such as Jarque-Beta test and Kolmogorov-Smirnov test and Q-Q probability chart, next, tests if its returns are nonlinear, using the surrogate data method are presented.

Based on the Kolmogorov-Smirnov statistics,a set of continuous confidence bands with asymptotic coverage are constructed.

Effect of Distance between Clamp and Cutting Notch on Plywood Bond Strength Testing;

Measurement of the distance between uretero and uterine neck in the condition of enlargement of uterine neck;

Study on the Correlation of Distance and Angle with the Image of Laryngostroboscope;

Joint frequency、direction of arrival and range estimation for near-field sources;

The speed of moving-target was measured based on the principle of PD frequency shift,and the range of moving-target on the pulse-echo principle.

For the accuracy of range information is higher than that of azimuth information received by networking radar system,three-dimension target location based on range only is proposed by using the linear least square iteration algorithm.
