Also, the performance of four techniques, using different approximation to estimate the equivalent peak value of shear stress and strain were investigated for the purpose to determine the equivalent shear modulus, damping, excess pore water pressure and residual strain induced by seismic loading, in which the equivalent peak value was computed in terms of its standard deviation and the corresponding peak factor.

利用上述动力有限元程序分别对水平地基进行了总应力、不排水有效应力和排水有效应力随机动力响应分析，并通过4种不同的方法来计算地基的等效剪切模量、阻尼比、振动孔压和残余剪应力。

A GVF snake model was used to link discrete edges, the linked edges were kept well accordance with fringes of phase map. 4Phase unwrapping algorithm based on edge detection is suitable to well separated fringes, the unwrapped phase can be rewrapped to the original phase map.

对一幅干涉相位图的滤波结果表明，该算法很好的抑制了斑点噪声，极大的降低了残余点的数量，保持了条纹边缘和相位细节信息，并使绝对相位保持在一定的动态范围。

The results showed increased manganese solids composition percentage with higher iron and manganese oxidation efficiency. The results show higher oxidation efficiency could be proved by the lower residual manganese concentration in water.

在SEM/EDS观测滤纸上的沉淀物中发现，薄膜表面锰氧化物的组成比例有增加之趋势，表示氧化效果越佳，此结果也可由残余锰浓度相互印证。

The similarity shows their affinity, and the differences reflect the attributes of partial melting relicts of inclusions.

In the latter groups, rats were bled to a mean arterial blood pressure of 40 mm Hg(1 mm Hg=0.133 kPa) and maintained at this level for 1, 2, 3 hours, respectively. The pressor response of blood pressure and the contractile response of superior mesenteric artery to norepinephrine(NE, 3 μg/kg) were observed after shed blood was reinfused.
