热致性液晶共聚酯的剪切流变行为

采用毛细管及锥板流变仪对ＰＥＴ／ＰＨＢ系液晶共聚酯ＬＣＰ８０的剪切流变行为进行了系统的研究，发现在较低剪切速率下ＬＣＰ８０即出现剪切烯化现象，因此在通常的加要剪切速率范围下粘度非常低；当温度大于３００℃后粘流活化能减小，粘度的温度依赖性明显减弱；由于过冷现象热史影响其流动曲线，并且经预剪切后粘度显著下降；在较低剪切速率下第一法向应力差出现负值，并开始表现出明显的弹性效应。

卡森流体表现粘度随切变率增大而下降的原因分析

卡森流体的经验公式为：√τ＝√τｃ＋√ηｃγ其表现粘度ηａ为√ηａ＝√τｃ／√γ＋√ηｃ。该式中的卡森屈服值（τｃ）和卡森粘度（ηｃ）在一定切变率（γ）范围内，是不随γ而变化的常数，因此，ηａ随γ增大而下降的原因只能用ηａ∝１／γ的关系来解释，这种反比关系必须在τｃ≠０的条件下才成立，否则，卡森流体变为牛顿流体，卡森粘度粘度属动力性粘度，在圆形管道中，其存在下栓流与管壁之间，相对滑动的液层内，血液

ABA／PET液晶共聚酯酰胺的结构与性能

研究了对象基苯甲酸（ＡＢＡ）／聚对苯二甲酸乙二酯（ＰＥＴ）液晶共聚酯酰胺的晶体结构，以及热性能、流变学和力学性质。广角Ｘ射线衍射研究结果表明ＡＢＡ链节的引入使ＰＥＴ的晶态结构发生畸变，但大部分结晶衍射峰仍然存在。随着ＡＢＡ含量的增加，各晶面间距基本不变，微晶尺寸显著增大，结晶度急剧降低。差示扫描量热分析和热失重结果表明共聚酯胺具有优良的热稳定性，并且随着ＡＢＡ含量的增加，共聚物的热稳定性提高，共聚     

PBT／PC共混体系流变性能与形态结构研究

采用毛细管流交仪测定了ＰＢＴ／ＰＣ共混物的表观粘度、剪切应力，观察了不同共混物组成和不同温度下共混物的流变行为，并借助扫描电镜对共混物和微观形态结构进行分析。结果表明：ＰＢＴ／ＰＣ熔体共混物的流变行为接近假塑性流体．温度对共混物的流变行为影响很大，共混物的熔体粘度在ＰＢＴ／ＰＣ为９０／１０和６０／４０时呈双极值．共混物为两相结构，ＰＣ含量为４－５０％时呈两互锁结构。

Survey and practice of reporting quality of randomized controlled clinical trials on traditional Chinese medicine

Evidence obtained from randomized controlled trials （RCTs） has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine （TCM） and results have shown that there is an urgent need for higher quality RCTs on TCM.     

TCM Treatment of Ankylosing Spondylitis by Tonifying the Kidney and Strengthening the Governor Vessel

Ankylosing spondylitis is a chronic and progressive disorder with inflammation mainly involving the central axis joints. It mainly affects the cervical spine and the lumbosacral area, with the pathogenesis closely related to the kidney and the Governor Vessel (GV). TCM holds that the syndrome is deficiency in origin and excess in superficiality, which is due to insufficiency of the kidney, deficiency of GV, and blocking of the channels with the invasion of exogenous evil, leading to poor circulation of qi and blood and malnutrition of the bones, muscles and joints. The TCM method of tonifying the kidney and strengthening GV to regulate circulation of qi and blood and check the arthralgia pain should be adopted, with the Kidney-Tonifying and GV Strengthening Decoction (益肾强督汤) prescribed.
