And by using the initial conditions as well as the end conditions, the dynamic problem is then transferred to a second kind Volterra integral equation about the function of the axial strain with respect to time which can also be solved successfully by the interpolation method. For piezoelectric and pyroelectric hollow cylinders, by following the solving procedure for elastic hollow cylinder and by using the electric boundary conditions, the dynamic problems are transferred to two Volterra integral equations about two functions of time, one is axial strain and the other is related to electric displacement, which can also be solved efficiently and quickly by employing interpolation method. The elastodynamic solutions of hollow spheres, which are made of elastic, piezoelectric and pyroelectric materials, respectively, for spherically symmetric problems are also obtained.

Results: The changes following hydrocortisone intervention of rats could be identified by PCA, and the kidney deficiency syndrome rats entered a state of "hyperfunction", involving a series of changes in metabolic pathway and metabolic network. The response integral area of lactic acid (δ 1.37) increased, indicating the accumulation of metabolites of lactic acid. The amount of dimethylamine (δ 2.72) also increased, indicating that the disorder of kidney function was related to kidney-deficiency syndrome. The response of creatinine (δ 3.87), asparaginic acid (δ 2.83), taurine (δ 3.44, 3.28), and hippurate (δ 7.84, 7.56, 7.64, 3.97) all decreased significantly, indicating that the hydrocortisone might cause adrenal cortex excretion injury. The response integral area of succinate (δ 2.41) and citric acid (δ 2.53, 2.68) decreased, which was usually caused by disorder of the mitochondrial function.

结果：PCA方法处理肾虚证和空白对照大鼠尿液数据显示，两组大鼠的数据可以在得分图实现分类，与对照组比较肾虚组大鼠由于氢化可的松诱导，大鼠机体进入一个过消耗后衰弱的状态，相关代谢发生显著变化，乳酸(δ 1.37)代谢发生堆积；二甲胺(δ 2.72)的含量增加，提示肾虚与肾功能异常是密切相关的；天冬氨酸(δ 2.83)，牛磺酸(δ 3.44， 3.25)，马尿酸(δ 7.84， 7.56， 7.64， 3.97)，肌氨酸(δ 3.87)等的相对积分面积明显下降，这预示糖皮质激素可能引起了肾上腺皮质分泌功能的损害；琥珀酸(δ 2.41)和柠檬酸(δ 2.53， 2.68)是三羧酸循环能量代谢及糖酵解的中间产物，其含量的降低，通常是由于线粒体功能紊乱所引起。
