  transformed huang equation
     At the same time,it is noted that the parameters of the transformed Huang equation are not universal and cannot be used to characterize completely the viscoelastic properties of the LDPE melt. The stress relaxation after cessation of steady shear cannot be described by the transformed Huang equation.

With the Low Shear 30 rheometer and its accessory instruments, two torque decay curves of whole blood from young men(n=32) and women (n=32) were recorded at shear rate 1.285s~(-1) and 2.37s~(-1) respectively. Following Huang's equation, using the non-linear parameter estimation method, we calculated the five thixotropic parameters. The procedure was quiet simple and very easy to be popularized. The results of measuring were comparable to that in Huang's paper. The relationship between HCP and these parameters in the study is consistent with that in our published commumication. The values of τ_o, μ, (ηs-μ), A, ARC in men group were higher than those in women group, but there were no statistical differences of the values of C or n between the two groups. This paper discussed the possible reason of these differences. It was likely that the differences were attributed to higher HCT in men group than that in women group.

本文用Low Shear 30流变测定仪及其附件,记录切变率分别为1.285和2.37秒~(-1)时男女青年全血的二条扭矩衰减曲线,按Huang方程,用非线性参数估计法,计算出五个触变参数,方法较简便,便于推广。其结果与Huang的报导很接近。这些参数与红细胞压积(HCT)之间的关系和我们以前的结果是一致的。男女两组,各有被试者32例;男子组的τ_0,μ,(ηS-μ),A,ARC明显大于女子组,而c和n值在两组间无明显差异,本文认为造成这种差异的原因,可能主要是由于男子组的HCT明显高于女子组。

The modifiedLevenberg-Marquardt non-linear parameterestimating method was used tocalculate the thixotropic parameters byfollowing Huang′s equation, The resultsshowed that the thixotropic properties ofwhole human blood could be measured byrecording two torque decay curves. Thispproach is much easier than Huang′smethod. We have adopted it to measurethe thixotropic propeties of whole bloodfrom healthy young men (n=32) and youngwomen (n=32). The results were compa-rable to those in Huang′s reports of 1976.The coefficients of variations of most pa-rameters in our measurement were lessthan those in Huang′s reports. Meanwhile,we analysed the advantage in using thenew method and made some suggestionsto improve the measurement accuracy inhuman blood thixotropy.

本文用Low Shear-30流变测定仪及其附件,通过记录切变率分别为3.23,2.37,1.747和1.285s~(-1)时正常人全血的4条扭矩衰减曲线,采用改良的 Levenberg-Marquardt非线性参数估计法,按Huang方程计算出血液的5个触变参数。结果发现,记录两条扭矩衰减曲线即可较准确地测出人体全血的触变特性,该方法简便易行。作者用此方法测定了健康男、女青年血标本各32例,其结果与 Huang的报道相近,而且各参数的变异系数均优于Huang测定的结果。

The thixotropic parametersof whole blood in two groups of childrenwith congenital heart disease (CHD) weremeasured.Group 1. cyanotic heart disease(CCHD), zo cases) Group 2. acyanotic heartdisease (ACHD), 30 cases. Fifty healthychildren were controls matched with thepatients in sex and age. Their thixotropicparameters were compared; the paired t-test was used. In the children with CCHD,the hematocrit (HCT), the yield stress(T_0)the Newtonian contribution of viscosity (μ).the equilibrium value of the structural pa-rameter(A), the apparent viscosity at 2.37Sec~(-1)(η_?) and the Non-Newtonian contri-bution of viscosity(η_?-μ)were significantlyhigher than the in corresponding controlgroups. In the children with ACHD, onlythe values of T_0, η_?-μ,and η_? were higherthan those in control groups. All of thethixotropic parameters in CCHD groupwere significantly higher than those inACHD group. Thus we described quantita-tively CHD in terms of thixotropy of blood.The thixotropic parameters of blood couldbe used as indexes of severity forpathologic changes of CHD.

以Low-Shear 3.0流变测定仪,据Huang的方程,用改良法测定20例青紫型先天性心脏病(CCHD)和30例非青紫型先天性心脏病(ACHD)患儿及相应健康对照组的全血触变参数,并进行比较。结果:ACHD组仅τ_0、η_、(η_s-μ)增高;CCHD组红细胞压积、τ_0、μ、A、η_s、(η_s-μ)明显增高,较健康对照组分别增加1.76、6.99、3.63、2.75、6.68及4.66倍,较ACHD组分别增加1.76、5.13、3.40、2.75、5.25及3.99倍。提示先天性心脏病(CHD)患儿全血触变参数可作为判断患儿病情及预后,为早期防治并发症提供理论依据。
