The average diameter decreases monotonically with increasing effective confining pressure,which is defined as the difference between confining pressure and pore water pressure.

试样的平均直径随着有效围压的增长而单调减小。在此，有效围压被定义为围压和孔隙水压之差。

MethodsFrom the biceps brachii, tibialis anterior and vastus medialis muscles,the duration, amplitude, area and the ratio of area to amplitude of the MUPs were obtained by use of the spike-wave triggered average technique in 10 patients with myopathic disease, 13 patients with neurogenic disease and 22 healthy adults.

选取 10例肌肉病变患者、13例神经病变患者和 2 2例正常人，采用棘波触发平均技术，获取肱二头肌、胫前肌和股内侧肌MUP的时限、波幅、面积和面积/波幅比 4项参数，通过SPSS10 。0软件进行方差分析和判别分析。

It is shown by analyzing large test data that the empirical formula presented in the paper has higher linearly dependent coefficient, lower average relative error and relative standard deviation compared with the traditional empirical formula of orthoscopic and power function.

试验数据表明，本文提出的经验公式比传统的直线式和幂函数式经验公式的线性相关系数更高，且平均相对误差和相对标准差都低。

Order determination is accomplished in two stages, i.e., the AR order is first determined by the minimum eigenvalue of overdetermined instrumental variable product moment and the MA order is then estimated by the minimum eigenvalues of a covariance matrix derived from the observed data.

该方法将ARMA模型的结构辨识分两步进行：首先利用超定辅助变量乘积矩(0IVPM)的最小特征值确定自回归部分的阶，然后利用协方差矩阵的特征值估计滑动平均部分的阶。

Of 62 cases, one case had according to Harris criterion 56 cases were excellent,(rate 90.3%) and 2 cases good (3.2%) excellent and good rate of the function of the hip joint was 93.5%.［Conclusion］The improved PFN is a useful device in the treatment of perit rochanteric fractures of the femur.

结果］有15例失去随访，住院期间无死亡病例，后期随访中有4例死于其他系统疾病。62例获得随访，时间12～47个月，平均28.6个月，骨折全部愈合，参照Harris髋关节功能评分标准评价术后功能，优56例，占90.3％，良2例，占3.2％，差4例，占6.5％。

The results indicates that the years average equilibrium difference between recharge and discharge is -21.76×108m3/a, resulted from cosmically and high strength exploitation and resulting in water table's coming down persistingly.

研究表明，大规模高强度开采条件下，华北平原浅层地下水系统多年平均补排均衡差为-21.76×108m3/a，导致浅层地下水水位持续下降。
