粘滞性

7 A porous medium has a permeability of one darcy when a single phase fluid of one centipoise viscosity that completely fills the voids of the medium, will flow through it under conditions of viscous flow at a rate of one cubic centimeter per second per square centimeter cross sectional area under a pressure or equivalent hydraulic gradient of one atmosphere per centimeter.

Through a study of 504 cases of observation group with eye-signs in blood stasis syndrome and 112 cases of control group without eye-signs in BSS,it has been found that in the observation group, the scores of the blood concentration,viscosity, aggregability and coagulability,level of plasma thromboxane B2(TXB2),and the ratio of TXB2/6-keto-PGF1 α were obviously higher than those in the control group,but level of 6-keto-PGF1 α was obviously lower than that in the control group; the above-mentioned param...

本研究通过对504例血瘀证目征观察组和112例非血瘀证目征对照组研究发现，观察组血液浓稠性、粘滞性、聚集性和凝固性积分值，血浆血栓素B2（TXB2）水平、TXB2／6－酮－前列腺素F1α（6－keto－PGF1α）比值均明显高于对照组，而血浆6－keto－PGF1α水平明显低于对照组，表现为血液高粘滞综合征者占90.08％，明显高于对照组2.68％，两组比较均有非常显著性差异（P＜0.001）。本研究为血瘀证目征提供了部分病理基础。

It is proved that the prime of life is the important phase in which blood start to curdle and blood system diseases occur.

本文证明，青壮年是血液粘滞性和凝固性由正常转变为异常的重要时期，也是发生血液系统疾病的重要时期。

Further analysis illustrated that similarities and differences lie in the RE of CHD and CAS. Blood stasis and cbronic broncbitis are similar RF of both diseases; similar but different Rf covered liver deficiency, hypertension, diabetes, year of hyperlpemia, high blood sugar, tigh blood stasis, high cbolesterol. Among them, bigher positive rate of liver deficiency, hypertension and diabetes, longer year of hyperlipemia, higbef blood sugar, more serious blood stasis remain in CHD while higher cholesterot existing in CAS in this study. Moreover, qi deficiency, heart deficiency, Phlegm, senility index, putse pressure, LOP, TG, HDL/TC, Low putmonary 、function are different RF of both diseases.

进一步分析CHD和CAS易患因素异同的结果表明：CHD和CAS，相同易患因素有血瘀、慢支；同中有异的易患因素有肝虚、高血压、糖尿病、高脂血症年限、高血糖、高胆固醇、血液粘滞性增高；其中CHD的肝虚、高血压和糖尿病发生率较高，高脂血症年限较长、血糖较高、血液粘滞性严重，CAS的总胆固醇在本次分析中较CHD高；不同易患因素有气虚、心虚、痰浊、衰老指数、脉压、LPO、TG、HDL/TC、肺功能低下。

Colloid can be used to control the flow variability, thixotropy, proliferation, viscosity and consistency, is an effective flow control agents and thickeners.

可用来控制胶体的流变性、触变性、扩散性、粘滞性和稠度，是一种有效的流变控制剂和增稠剂。

But in actual experimental process, the viscous force of friction has influenc in the varying degree to the measurement result when the initial velocity of the slide block is different.

在气垫导轨上做碰撞实验，最大限度地减少了摩擦阻力的影响，但在实际的实验过程中，仍发现滑块的初速度不同时，粘滞性摩擦阻力对测量结果有不同程度的影响，为此在气垫导轨上增加了电子发射装置，较好地控制滑块的初速度和测量滑块的加速度，从而减小粘滞性摩擦阻力对测量结果的影响。

Results The bletilla colloid was a homogenous viscous colloid whose relative viscosity was 2324.6 mm2/s. It was easily injected through 4-F catheter and hyperattenuating under fluoroscopy, meanwhile, with good histocompatibility and hemo-compatibility, without pyrogenetic response and toxicity. In vitro, the mixture of bletilla colloid and MMC did not produce separation and suspention phenomena but released 50%of MMC at 1.8h and 100%at 3.4h. The bletilla colloid mainly embolized peripheral arteries, maintaining occlusion for 5 weeks and without formation of collateral circulation. The injuries of normal hepatic tissues were slight, without hepatic cytonecrosis.
