After treatment with the above hormones, the rats were established anesthesia with urethan (1g/kg, i. p.); polyethylene catheters were inserted into the external jugular vein and the common carotid artery for drug administration, and then blood pressure was recorded. The arterial catheter was connected to a pressure transducer, and the blood pressure was displayed on the channel of BL-310 Experimental System of Biological Function through IBM computer. We assessed the changes of resting arterial blood pressure, the pressor responses of angiotensin Ⅱ(Ang Ⅱ, 0.01mg/kg), noradrenaline (NA, 0.01mg/kg) and adrenaline (Adr, 0.016mg/kg). The depressor responses of Ach (0.006mg/kg) and carotid sinus baroreflex were also discussed after treatment with the hormones in OVX rats.

用不同雌激素处理21天后，将动物用25％的氨基甲酸乙酯腹腔麻醉（1g／kg），做颈总动脉插管，通过压力换能器，将血压变化输入计算机，通过BL-310智能型生物信号显示与处理系统的压力测定模块，观察去势鼠及不同雌激素替代治疗大鼠静脉注射血管紧张素Ⅱ（AngⅡ，0.01mg／kg）、去甲肾上腺素（NA，0.01mg／kg）、肾上腺素（Adr，0.016mg／kg）的升压反应以及乙酰胆碱（Ach，0.006mg／kg）的降压反应和压力感受性反射的变化。

Use viscometry to determine viscosity-average molecular weight of oxidated polyethylene wax and introduce the measurement,process and effect factors in detail.

用粘度法测定氧化聚乙烯蜡的粘均分子量。

The molecular weight and molecular weight distribution of polyethylene were determined by GPC and Viscometry.

对GPC曲线的高斯函数拟合分峰，计算在双组分茂金属催化体系中每种催化剂得到的聚乙烯的重量之比；根据各催化剂的催化活性和按所加的催化剂的摩尔比例假定进行独立反应时，可以计算在双组分催化体系中每种催化剂得到的聚乙烯的重量之比；根据两种重量之比的比较结果和对双组分茂金属催化体系得到的聚乙烯的平均分子量和平均分子量分布的分析结果，可以推测在催化体系CatZr〓/CatZr〓中两种催化剂基本上不存在相互作用；而在CatZr〓／CatZr〓体系中两种催化剂之间可能有相互作用存在。

Low temperature significantly prolonged fruit storage life,delayed the total sugar,total acid and V_C content loss.Between 2 ℃ and 12 ℃,the lower the storage temperature,the better preservation effect.The best storage temperature of wampee was 2-4 ℃. MAP storage could delay the!quality loss of wampee.0.025 mm polyethylene film with the packing capacity of 5.4 kg·m~(-2) were recommended.

结果表明，常温下黄皮果实贮藏期短，常温贮藏3 d后，好果率低于75%；低温能明显延长果实的贮藏期，延缓果实的糖、酸和VC含量的下降；在2-12 ℃间，贮藏温度越低，保鲜效果越好，适宜的贮藏温度为2-4 ℃；采用MAP保鲜技术能延缓果实品质的下降，在2-4 ℃下大鸡心黄皮MAP保鲜的适宜条件是采用0.025 mm的PE膜包装，装果量为5.4 kg·m-2。
