When the undrawn films were annealed atthose temperatures, the morphologies in the lamellar crystals had change. WAXDand iR studies shown that the crystallinities incrcand, dimensions in (002) and(020) normals increased while that in (200) fold had slight decreases. The rela-tionship between the orientation of the drawn UHMWPE gel-films and the struc-ture changes and the optimum drawing temperature had been disscussed.

通过IR及X－ray衍射等方法研究发现，拉伸前用不同温度退火处理后，凝胶膜的片晶微结构产生明显变化，在对应于超高拉伸温度范围内，其结晶度增加，微晶的c和b轴方向尺寸变大，而a轴方向的尺寸减小，从理论上对这一变化过程作了考察，并讨论了超高拉伸取向性与这些结构变化的关系以及可超拉伸取向性的最佳温度范围。

However, so far there are no reports on the effects and mechanisms of chitosan with a special molecular weight on extending the storage life of fruit and vegetable. Here chitosan of a special molecular weight was employed to study its effects and mechanisms on the preservation of strawberry, Huanghua pear, green pepper, tomato, mango.

本试验采用特定分子量的壳聚糖，选择草莓、黄花梨、青椒、番茄、芒果等多种类型果蔬为试材，从不同分子量的壳聚糖最佳配合及其成膜性、抗病性，以及添加助剂的优化和对常温贮藏果蔬保鲜的生理生化效应等方面开展研究。

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。

In order to make these silver paste successfully used in commercial, a clear understanding is required for the complex relation between different parameters such as particles size, solid volume fraction, packing density on suspension printing and deformation and the mechanism of silver powder sintering shrinkage and the inorganic adhesive effect under the batch manufacture condition.The main emphasis of our researches was to improve the silver paste properties by developing a reliable, screen-printing paste suitable for fine lines and lower sintering porosity and good interface between thick film and glass substrate.
