The results showed that the herb was rich in vanadium and lithium and tin, but low in zinc and copper, and had a strong tendency to accumulate titanium, lithium and boron. The pharmacological effects of geo herbal Asarum L. seemed to be closely related with its characteristic contents of trace elements which were mainly affected by the idioplasm and various other minor factors.

结果显示,细辛道地药格中V、Li、Sn等元素的含量较高,Zn/Cu比值较低,细辛对Ti、Li、B等元素有较强的富集作用,细辛的药理活性与细辛道地药材的微量元素含量特征有一定的相关性,种质是影响细辛道地药材中微量元素含量的主要因素,从微量元素的角度来看,细辛道地药材的形成模式是以种质为主导的多因子关联决定型。

On conditions that sports technology come into being , keeping on adding load training will help improving sports technology. Further research declares that nerve connection which is set up by shaped action will be broken and new connection will be expended and differentiated till a new movement fixed after sports technology coming into being and sports intension overload. So sports technology is relative to a certain load training intension.

在运动负荷强度对运动技能形成的影响中,传统观念认为适宜的运动负荷强度有利于运动技能的形成,但是这里所指的运动技能的形成,实际上是建立在某一运动负荷强度下所形成的运动技能,当运动负荷强度超过原来已经适应的运动强度负荷时,已巩固了的运动技能动作所建立起的神经联系又被再次打破,产生新的泛化、分化直到建立新的动力定型。

On the basis of study of fault seal history, together with the obtained achievement of structural stress field and fluid potential field, it is discovered that for the pool-forming process of oil and gas in the studied area the fault seal of nowadays is better than that of the Ed and Ng stages, it plays an important role to determine the oil column height and hydrocarbon preservation.

在断层封闭史研究的基础上,结合构造应力场及流体势场的研究成果,揭示了研究区油气的成藏过程,阐明了现今断层的封闭性优于Ed、Ng期断层的封堵性,并对油气的保存以及油柱高度的最终定型具有重要意义,而Ed、Ng期断层的封闭性对油气的分布态势有重要的影响。
