  coagulation curves
(3) The experimental data of mercury droplets agree with the theoretical coagulation curves quantitatively, if we take the Hamaker constantA = 2.4 X,10-12 erg.
      


Polystyrene colloids were obtained by emulsion polymerization using the silvcr/bisulfite redox initiation system. The colloid stability of this system against the addition of different types of electrolytes has been studied. The results showed that the slope of the coagulation curves did not exhibit a dependence upon the counterion valence and the CCC did not follow the Schulze-Hardy rule.The Hamaker constants calculated from the CCC's values were in reasonable agreement with those found by previous workers....

The coagulation processes can be easily and accurately followed by means of 90° light scattering measurement. When the particle sizes were large compared with the wave length of the incident light, the optical angle for the measurement of scattering must be used, which could be calculated by Lips-Willis equation.

用新引发体系乳液聚合制得低电位的聚苯乙烯胶体.通过电解质对胶体的凝聚动力学研宄,发现电解质的临界凝聚浓度(ccc)与反离子价数间的关系不符合Schulze-Hardy规律;但从ccc计算的Hamaker常数与理论值相接近.由凝聚曲线斜率求得胶粒表而电位(φ_δ)与由电导滴定结果计算所得的表面电位(φ_ο)相当.胶体凝聚过程可用散射光检测,对较大胶粒的光散射检测角,发现可通过Lips-Willis式来估算.

Though the detection of the change of shear stress in blood,four coagulation parameters(tr、△T/△t、 Tmax、S) can be automatically determined. The instrument can be used to automatically detect the process of bloodcoagulation and print coagulation curves. There is a great difference between different samples while there is a good repeatability with the same sample.

OBJECTIVE To study the principle of dynamic response frequency in piezoelectric coagulation and(establish) a new method for endpoint determination of the analysis.METHODS A new dynamic piezoelectric(frequency) response model and endpoint determination method for the piezoelectric coagulation were derived,based on the theoretic analysis of viscosity and density changes in coagulation reaction system.The different final(segments) of the raw data among different coagulation curves were cut or extended respectively when a prothrombin test was performed by different reaction models.Then judged and compared the endpoint of coagulation reaction between new endpoint determination method and the old method-maximal curvature of fitting curve(MCF).(RESULTS) The trend of dynamic frequency response of piezoelectric coagulation corresponded with the inverse S curve F=(f_0-⊿f)+⊿f1+e~((t-t_0)/dt) derived from theory according to the change regularity of the viscosity and density in the reaction system.Compared with the MCF,the inverse S-fitting determination method(ISF) based on the new model could improve the reproducibility(P<0.01) and save more detection time(P<0.01).(CONCLUSIONS) The new derived inverse S model can represent the principle of the dynamic frequency response perfectly,and the ISF based on it can be used for the endpoint determination in piezoelectric coagulation.

目的探讨体外凝血反应引起压电传感器频率变化的规律,建立压电凝血终点判断模型。方法理论分析凝血反应导致反应体系黏度密度变化规律,推导适合的频率动态响应模型并建立新的压电凝血终点判断法;用建立的反应模型检测凝血酶原时间(PT),并删减和延长不同长度的原曲线末段,然后以新方法和既有的最大拟合曲率判断法(MCF)判断终点并比较。结果根据反应体系黏度密度变化规律,理论推导出体外凝血反应过程中压电频率动态响应规律符合F=(f0-?f)+1+?e(t-ft0)/dt模型;根据该模型建立了新的反S拟合曲线法(ISF);与既有的最大拟合曲率法相比,前者检测速度更快(P<0.01),重复性更好(P<0.01)。结论该反S模型可以较理想地反映凝血反应中压电频率动态变化规律,ISF法可以理想的判断压电凝血终点。
