实验研究

A laminated model of cutting face for evaluating cutting quality has been built up on the basis of cutting experiments. The experimental results and the theoretical analysis of the model show that, the lower part of the cutting face, adjacent to the bottom edge, has the worst cutting quality due to its worst roughness.

在工艺实验的基础上，建立了切割面分层理论模型，实验研究和模型分析表明：切割面近下缘处是切割质量的最薄弱环节，此处粗糙度最高，切割前沿在下缘处的温度是决定下缘质量的主要因素。

In order to verify the validity of the mathematical models and the calculation method, a series of experiments on the performance of an air-conditioner under variable conditions was conducted in the psychrometric rooms.The performances of the proto type under the different inlet air temperature of the condenser and evaporator, as well as the different face velocity of the condenser and evaporator was measured.

The achievement in practical research, especially experimental research on autonomous learner training, is far more inadequate.

另外已有的英语自主学习研究大多集中在理论的研究上，其应用研究的成果还相当的少，尤其是自主学习训练的实验研究，还是远远不够的。

Background: New studies showed that changes in the balance between haemostatic and antithrombotic processes, including a prethrombotic state might contribute to the development of atherosclerotic lesions which occured in hypertensive vascular complications. This may be one of the causes that satisfactory blood pressure reduction with antihypertensive drugs does not lead to an equal reduction in heart attacks and strokes. With the development of traditional presentation of blood coagulation, the role of tissue factor pathway has been emphasized.

中文题名原发性高血压患者组织因子途径变化与血栓前状态关系的临床与实验研究副题名外文题名 Clinical and experimental study of relation between changes of tissue factor pathway and prethrombotic state in hypertensive patients 论文作者张卫茹导师孙明教授学科专业内科学研究领域\研究方向学位级别博士学位授予单位中南大学学位授予日期2002 论文页码总数70页关键词血栓组织因子高血压馆藏号BSLW /2003 /R544 /3 背景：新近的研究表明，凝血与抗凝系统失衡所导致的血栓前状态与高血压并发症的发生关系密切，这可能是高血压病人虽经有效的降压治疗但发生心、脑、肾、血管并发症的危险仍很高的主要原因之一。

The split between the two groups can hardly be papered over.
