In the first part of this thesis, Stress relaxation method set up in the software of DMA was used to perform the aromatic and aliphalic (D2192-BAPP) PI film stretching process. To study the optical anisotropies property to the light leakage from the crossed polarizers, we put the stretched samples into one set of crossed polarizers and as expected, the stretched PI films could reduce the light leakage at view angle of ±45 deg, and exhibited a visually observed compensating property of an A-plate. No color shift wasobserved, and the birefringence was very uniform. These results prove a uniform birefringence can be obtained by a stretched process for PI films.

首先，我们以动态机械分析仪的应力缓和模式对芳香族FDA-BAPP PI及脂肪族D2192-BAPP PI薄膜进行拉伸实验，并将拉伸后的PI薄膜置於一组相互交差的偏光片中观察其光学异向性，发现拉伸后的PI薄膜试片可以降低在±45o视角的漏光的效果，展现出如同A-Plate的光学补偿特性，所显现的光学补偿效果相当的均匀而且没有色偏的情形发生，证实以拉伸方法可以造成PI薄膜很均匀的双折射效应。

Secondly, we study a class of automorphisms of A, i.e., we prove that the set {φ∈SL_n|φ= t is a subgroup of AutA(n,t,Finally, we mainly discuss some properties of the operation w in A, i.e., g~w = 0, f~w = 0 and Leibniz identity.

其次，讨论了A的一类自同构，即证明了集合{φ∈SL_n|φ=t}是自同构群AutA(n，t的一个子群；最后，得到了A的运算w的一些性质，即g~w=0、f~w=0和Leibniz等式。

The results showed that (1) all the arteries tested had tachyphylaxis to peptidergic agonists;(2) the desensitization of the arteries tested to catecholamines was uneasy except BA;(3) the desensitizations to AⅡ, AVP and PE were homologous;(4) the endothelium-EDRF -cGMP pathway had no contribution to the tachyphylaxis of PA to AⅡ and AVP;(5) membrane receptor cycling (internaliation and re-insertion) contributed only in part to homologous desensitization;(6) there was no change in the function of voltage-dependent Ca〓 channel during desensitization to AⅡ and AVP;(7) some changes in G protein occurred during homologous desensitization;(8) the most surprising finding was that the caudal arterial smooth muscle of stroke-prone spontaneously hypertensive rat showed tachyphylaxis to α〓-adrenoceptor agonist PE, while the tachyphylaxis of pulmonary artery of SHR was not changed compared with that of Wistar rat.

脱敏是消除效应的一种有效方式。因此，研究不同血管对不同激动剂脱敏的差异及阐明脱敏的机制，有助于阐明血管活动个性化的机制。研究表明：血管对肽类激动剂的脱敏方式为快速脱敏，而对儿茶酚胺类激动剂不易脱敏；血管对肽类激动剂和儿茶酚胺类激动剂表现为同源脱敏；内皮-NO-cGMP通路不参与肺动脉对AⅡ和AVP的快速脱敏；用PAO抑制膜受体的内在化只能短暂抑制脱敏的发展，提示用膜受体数目的下调说不能完全解释同源脱敏；血管对AⅡ和AVP脱敏后VSMC细胞膜电压依赖性钙通道功能无改变；CA对AVP脱敏后GTPγS的量-效曲线下移，说明有G蛋白的变化，但这种变化并非G蛋白的亲和性改变；SHRsp之CA平滑肌对AⅡ和AVP的快速脱敏并未减弱，但对PE却表现为快速脱敏，这是我们首次发现的一个非常有趣的现象。
