Objective To investigate the difference between the effects of Ginger Extract and4-Retro-deˉcoctionon cardiac systolic/diastolic function of rabbit with heart failure.Methods 40pure-breed New-Zealand rabbits were randomly divided into4groups:low(0.028mL/kg),middle(0.056mL/kg),high(0.112mL/kg)dosage ginger group and4-Retro-decoction group.The heart failure model of rabbit was established by intravenous administration of20g/L pentobarbital sodium at a certain rate.Oral tube perfusion of ginger extract and4-Retro-decoction were administrated after the establishment of the model.Their hemodynamic changes were detected before and after the model establishment,and at5,10,15,20,30,45,60,90,120,150minutes respectively after the ginger administration by a RM-6004-graph physiological monitor.

The macroscopic rheological parameters and microstructure parameters were closely related, it is helpful to explain the essence of multiple rheological properties through the analysis of which the wax evolution process and microstructure of the crude oil which is waxy and high viscosity; the yield time of gelled waxy crude oil monotone increases along with the decreasing of rate of shear (the time of stress effect prolonged), there was power function relationship between them, it can be expressed with ; when adding diesel oil to Sudan crude oil, dilute proportion bigger the eccentricity degree of paraffin particles were bigger too, that was to say the symmetry of wax crystal was better, the wax crystal form fabric more hardly when the intermolecular interaction was smaller; in the light of macroscopica, the fall extent of the abnormity temperature, solidifying point and viscosity could be larger along with the accretion of dilute proportion, as a result, it's rheological properties could be improved.

SD原油析蜡点为94℃,析蜡高峰为50~30℃,异常点为40℃;其蜡晶颗粒细小、对称性差,所以具有较大的比表面能,容易形成联生、联锁结构;损耗角曲线与储能模量曲线或损耗模量曲线的交点所对应的温度与原油凝点或倾点温度非常接近,大约在39℃左右;也就是说,含蜡原油粘弹特性曲线的交点可以表征其流动性;原油宏观流变参数与微观结构参数密切相关,原油析蜡过程及蜡晶微观结构分析有助于诠释易凝高粘原油多重流变特性的本质;胶凝含蜡原油的屈服时间随剪切速率的降低而单调增加,二者显然存在幂函数关系,可用关系式描述;当SD原油加柴油稀释处理时,稀释比越高,蜡晶颗粒的偏心度也越大,亦即蜡晶对称性越好,分子间作用力越小,蜡晶颗粒越不易形成结构,宏观表现为异常点、凝点及表观粘度等流变参数下降的幅度越大,流动性越好。
