The hoop tension force is axisymmetrical about the tension direction and increase from the top position to both sides. The distribution of hoop tension force is even with small friction coefficient, but will increase rapidly from top to side positions, which subsequently result in necking and fracture near the edge of gauge section.

结果表明：采用正压力线性变化假设所得的切向力分布规律与拉伸实验结果吻合较好；切向力关于拉伸方向呈轴对称分布，从正上方到两侧逐渐增大；当摩擦系数较小时，切向力分布较均匀，但当摩擦系数较大时，切向力从正上方到两侧迅速增大，试样的颈缩和断裂发生在标距段内靠近标距边缘的位置。

RESULT: The K or K of laetrile, paeoniflorin and paeonol had no significant difference at concentration of 19.2~304.8, 18.4~329.5 and 7.8~125 μg/mL respectively or in four different regions of rat intestinal tract, the absorption quantity of laetrile, paeoniflorin and paeonol was proportional to its concentration respectively and the phenomena were not observed saturable. Except for Paeonol, the K and K of laetrile and paeoniflorin had no significant difference at pH value 5.0~7.4. The K or K of laetrile and paeoniflorin from the extration which contains one kind of active components was significantly less than that of same components from GuizhiFuling Capsule content.
