The microstructure and microhardness of the coating have been analyzed. On the base of orthogonal comparison tests, influences of many factors on the cracking sensibility of plasma metallurgy coating have also been studied. The results indicate that substrate and its surface condition, processing parameters and components of plasma metallurgy coating have great effects on cracking sensibility of plasma metallurgy coating. Through changing these factors, it is possible to reduce cracks and promote the applications of this technology.展开更多

The loading conditions in the experiments were designed to simulate the complicated loading process of underground rocks. The damages emerging inside the rock samples were recorded by the acoustic emission technique during the loading process. The experimental results were consistent with prediction by LURR theory. Integrating the changing processes of LURR value Y and the location process of acoustic emission events showed agreement between the variation of LURR value Y and the damage evolution inside the rocks. Furthermore, the high value of Y emerged before the complete breakdown of materials. Therefore, the damage evolution of rock specimen can be quantitatively analyzed with LURR theory, thus the failure of the rock materials and the earthquake occurrence may be predicted. The experimental results gave a further verification of LURR theory.展开更多

Methods Under microscope, the spleen was incised with parts of the portal vein and left abdominal aorta. Donor＇s portal vein and recipients external jugular vein was attached with cuff and then abdominal aorta and the common carotid artery was attached by the same method. This method was also compared with conventional suture method. Results Recipient operative duration in the new model was （31 ±5. 8 ）rain and the success rate was 75.6%. However, recipient operative duration in conventional model was （110±9.8）rain and success rate was 69.2 %. Concision This model can be established easily and the operative duration can be reduced. Biopsy can be perormed at any number of times safely and easily. The recipient can＇ t be contaminated and injured seriously. This kind of model enables us to perform secondary organ grafting into the abdominal cavity, It holds good to study the spleen transplantation and combined transplantation.refs,1 tab.展开更多

Methods: 70 cases were randomized into the control treatment group, with 35 cases each. The control group was given ACEI (captopril or manapril), diuretics (piozemi and polio), minimal betalol x, and digoxin, and the dose was adjusted according to the patient severity of the condition. On the basis of the treatment of the control group, the treatment group was given 4 Qiliqiangxin capsules (produced by Shijiazhuang Yiling Pharmaceutical Co., Ltd.), and the two treatment groups were given three times a day for four weeks. Results: Treatment group improved cardiac function and TCM syndrome compared with the control group (P 0.05). Conclusion: Qiliqiangxin capsule has a significant effect on coronary artery blood supply insufficiency, Yang deficiency and blood stasis syndrome. Based on my own years of work experience, the author mainly focused on observing the clinical treatment effect of pulmonary heart disease and heart failure, and shared the relevant information with colleagues in the industry, hoping to bring some progress to the relevant research in the industry.展开更多

In this paper, we present the point of view that the closer the relations are among elements in the system, the clos er they should be connected with each other when they are integrated in designin g and structural modeling of the workshop system. At first, this paper discusses the relationship among elements in the workshop system and events describing th e relationship, and provides a technical overview of the expression, definition and classification of relationship. This paper focuses on the steps and algorith m to evaluate the degree of closeness of relations among elements in systems, an d emphasizes the modeling methods for workshop reconfiguration by use of a fuzzy cluster. In light of the above steps and methods, types and contents of basic r elationships among elements should be determined, and a standard relation tree s hould be set up. Then, correlation coefficients are calculated by the standard r elation tree, and a fuzzy relation matrix is built up. After that, the structure modeling of the workshop equipment system can be completed through a fuzzy clus ter. The paper ends with an application of a FMS(Flexible Manufactuing System) f unction system modeling. Results of the modeling and calculations are presented.展开更多

The clinical symptoms of dysmenorrhea are lower abdominal spasm and pain, pale complexion, cold hands, feet, and severe cases are vomiting and syncope. Due to menstruation, dysmenorrhea can also relapse. There is no treatment for dysmenorrhea in western medicine now. According to traditional Chinese medicine, its cause is mainly Qi and blood disorders. The identification and treatment of TCM syndrome mainly starts with the cause of dysmenorrhea. In medicine, dysmenorrhea can be divided into qi stagnation and blood stagnation, coagulation blood stagnation, dampness and heat perfusion, weak qi and blood. TCM syndrome differentiation for treating dysmenorrhea has a good effect and is worthy of clinical promotion.展开更多
