If average values before or after catastrophe point when the pressure at both ends reduces exceed the threshold value, judging that there is leak and positioning: calculating approximate wavelet transformation coefficient of pressure data at both ends, initializing searching interval, calculating a signal time delay value corresponding to approximate wavelet transformation coefficient in the searching interval from maximal scale N; converting the time delay value under scale N to that under N-1 by geometric proportion relation; updating the searching interval, repeating above processes until the scale is 0 and positioning based on the time delay value.

若两端压力下降突变点前后的均值变化均超过阈值，判定有泄漏并进行定位：计算两端压力数据的近似小波变换系数，初始化搜索区间，从最大尺度N开始在搜索区间内计算对应近似小波变换系数的信号时延值，利用等比关系将尺度N下的时延估计值转换为N-1下时延估计值，以该值更新搜索区间，重复以上过程至尺度为0，以此时延估计值进行定位。

Here we found the optimum situation to determine LAP: the concentration of Tris-HCl is 125 mmol L^(-1) and the optimum pH is 7.2, temperature is 37℃, under this condition, Michaelis constant is 0.15 mmolL^(-1), ground substance concentration is 6.0 mmol L^(-1), with 157 health people serum samples (81 from male, 76 from female),x± s=35.7 UL^(-1)±8.2 UL^(-1), we established the method and reference value for clinical application and automatic analysis.

Leading the lovely princess to the most secluded and romantic place in that beautiful royal garden the prince heaped a hundred red roses on her lap, knelt before her, and taking her hand in his, said huskily,"My darling, I love you! Will you marry me?"

带着可爱的公主来到那个美丽皇家花园中一个最隐蔽最浪漫的场所后，王子捧了一百朵玫瑰到公主的膝上，单腿下跪，握着她的手，沙哑地说出了等待九年的话："宝贝，我爱你，请嫁给我！"

In other words, the threshold is set not only based on a relative level of jammer and noise but also the number of the jammed frequencies.

We use Hodges-Lehmann statistic to do significance test for those factors. The multiplication model is applied in the quantitative analysis and weighted least squares method is introduced to solve the multiplication model. Although the matrix of coefficients is not of full rank and the solutions of the multiplication model are not unique, we prove that all those solutions are equivalent in some sense.

Second, by analyzing the strain of northsouth blocks of the fault, we find an asymmetric displacement distribution between the two sides of the rupture, and the two blocks are subject to compressional and tensional stress respectively. It is a pattern that cannot be explained with the linear elastic theory. However, laboratory experiments and in situ measurements in boreholes have shown that many crustal rocks exhibit a nonlinear elastic behavior in compression and tension with a dependence of the Young's modulus on the minimum principal stress. So we suggest that the nonlinear displacement distribution should be considered when dislocation and hypocentral parameters are analyzed.
