To determine whether α1 and α2-adrenoceptors are located postsynaptically on renal vascular smooth muscle, a new method was developed as the following: the right renal vascular beds in the pithed rats were perfused with blood drawn from carotid artery at constant rate by a pump.

本实验用颈动脉血恒速满流毁脑脊髓大鼠单侧肾脏的方法,观察了高度选择性α_1受体阻断剂哌唑嗪和α_2受体阻断剂育亨宾与去甲肾上腺素、肾上腺素及电刺激肾交感神经对肾血管平滑肌的相互作用。哌唑嗪明显抑制电刺激引起肾灌流压升高,但尚存留一小部分既不能被增加哌唑嗪的剂量所阻断也不能被育亨宾所阻断。

The main works of this paper are as follows.First, according to the three-step method, 1-D unsteady flow model in river network is introduced. A new topological structure is presented to describe and store the topology information and data in river network ,which realises the connection between GIS and the numerical program of hydraulic calculating and turns the program into a universal one .A new formula of internal boundary conditions with double-recursion algorithm is deduced, and the relationship of recursive coefficient between imaginary channel length and non-imaginary channel length is presented ,which makes sure that the model can comprise the numerical simulation of the internal boundaries such as side pipe outflow ,barrage, slice gate and drainage pump station.

主要工作如下:(1)根据三级解法建立了一维河网非恒定流模型,并提出了一种新的数据结构来描述和储存河网拓扑信息,方便了GIS平台和数值计算程序的衔接,实现了三级解法程序的通用性;从河段方程组出发,根据虚设河段法推导出了内边界条件的双追赶法公式,指明了虚设河段的追赶系数和非虚设河段追赶系数的关系,从而使模型可以模拟集中旁侧入流、堰、闸、水泵等内边界对行洪过程的影响。
