To ensure close adhibition of connecting board, screwing should start from center to outside, that is, screwing from enlarged center to skirting area. To avoid coating's influence on tensile force, screwing work should be finished on one day. And to decrease prestress' difference of high-tension bolt, bolt screwing runs in two steps: primary screwing and final screwing. For large-scale joint with great amount of bolts demands a second screwing.

为使被连接板叠密贴紧，应从螺栓群中央顺序向外施拧，即从节点中刚变大的中央按顺序向下受约束的边缘施拧，为防止高强度螺栓连接副的表面处理涂层发生变化影响拉力，应在当天终拧完毕，为减少先拧后拧的高强度螺栓预拉力的差别，其拧紧必须分为初拧和终拧两步进行，对于大型节点，螺栓数量较多，则需要增加一道复拧工序。

In the past, the mainframe computers were used widely in hospitals. This kind of closed architecture provided centralize-control safety technology and multiple secure protections.

在以往医疗机构的资讯网路架构大多为较封闭性的大型主机中央控管系统，这类型的中央控制安全技术，经过多年精鍊后，变得非常成熟，所以系统多半拥有多层的安全保护，但封闭性大型主机因为建置及维护成本非常高，常需高额的预算与人力的投资。

After 1-month treatment, his best corrected visual acuity improved from 0.05 initially to 1.2, and the corneal thickness was not different between eyes. Nevertheless, at the injured sites, cornea was apparently thicker and corneal endothelial densities were lower than those in the fellow eye. This cornea might decompensate after any other ocular trauma or intraocular surgery.

经过一个月的治疗后，视力、眼压、中央角膜厚度、角膜上皮、前房、视网膜等皆恢復正常，但角膜內皮细胞密度明显减少，受伤部位的角膜亦明显较厚，日后恐有角膜失偿的危险，而这种情况无法藉测量中央角膜厚度显示出来。

Cells were shown in shape of round, ellipse and polygon. Cell body was loose and lucency with nucleus in center, cell membrane was also clearly seen. Cells were arranged in inlay and fuse in film after 12-14 days.2. Immunochemistry testNomogeneous immunochernical positive granules against CK13 were observed in endochylema of human conjunctiva cells.3. growth curve of conjunctival cellsSubcultured cells were aged and feeble after 5th passage.

The bone resection was divided into four steps via FLA:① drilling of the jugular tuberculum;② partial mastoidectomy;③ removal of the occipital condyle;④resection of the lateral mass of C1 with mobilization of the vertebral artery. After each step of the bone resection was completed, the exposed area of the central clival depression and the area of exposure 15 cm above the central point were calculated.

Methods Central point at the central clival depression was marked with the help of CT and stereotactic apparatus in 20 formalin-fixed cadaveric heads. The bone resection was divided into four steps via FLA:① drilling of the jugular tuberculum;② partial mastoidectomy;③ removal of the occipital condyle;④resection of the lateral mass of C1 with mobilization of the vertebral artery. After each step of the bone resection was completed, the exposed area of the central clival depression and the area of exposure 15 cm above the central point were calculated.

The biomechanical tests showed that two kinds of artificial bones had not significant difference on compressive strength and Young\'s modulus(P＞0.05),while the flexural strength of nano-nacre artificial bone was less than the control group(P＜0.05).3.The results of CCK-8 showed that the difference were not significant in each group,the proliferation of osteoblast reached the peak at the 5th day;7 days after being co-cultured,the total protein content of study group was higher than control group and blank group(P＜0.05),while the difference between control group and blank group was not significantP＞0.05The difference of alkaline phosphatase activities among three groups was not significant(P＞0.05The SEM view showed that osteoblast attached and grew well in two kinds of artificial bone.4.X-ray photography showed that two kinds of powder started to degrade in 2 weeks;this phenomenon became more appear in 4 weeks,nano-nacre powder degraded faster than micron-nacre powder,while the hole shadow was easy to be found;in 8 weeks,all the femoral holes recovered and returned to normal bone mineral density in all groups.Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone grew fastest around the bone defect area in study group,while most slowly in blank groupP＜0.05 SEM(scanning electron microscope observation showed that nano-nacre powder degraded more quickly.The same result can be found through the demineralized sections morphometric analysis,and both of the composite artificial bones made from those two kinds of nacre powder had the good connection with the adjacent tissue in rats body without apparent inflammatory response.5.X-ray photography showed that rabbit\'s bone defects healed faster in study group since NNAB implanted than in control group since MNAB implanted.At 24 weeks after operation,bone density in radial defects had nearly accessed to the normal area,while lower in control group,and turned up nonunion in blank group;The checking of BMD showed that results in study group were higher than those in control group at 8,16 and 24 week(P＜0.05), and the difference between the BMD values in study group at 24 week and those in blank group was not significant(P＞0.05).The gross specimens showed satisfactory histocompatibility both in study group and in control group,with bone tissue growing from two sides into the center of implanted materials; Normal slices in HE stain and hard tissue grinding slices in Stevenel\'s blue/Van Geison\'s picro-fuchsin stain showed that the bone growth tendency was better in study group than that in control group,and the medullary cavity had been penetrated to the implanted materials in study group at 24 week;Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone in both groups grew fastest 8 weeks after surgery,while slow down at 16 week.

In 1982 Chen was invited to conduct the Asben Festival Orchestra in America and was hailed as a success. In 1984, Chen was appointed President of Shanghai Symphony Orchestra, and two years later was appointed Music Director, the first music director of any performing groups in Chinese history. Since 1985, Chen has appeared in nations and regions including the former USSR, Japan, Italy, the USA, the Great Britain, Switzerland, Korea, the DPRK, Thailand, Singapore, Australia, Germany, Denmark, Austria, France, Spain, Russia, Hong Kong, Macau and Taiwan, conducting native orchestras. In 1998, 1999, and 2000 he led the Central Chinese National Orchestra on its tours to many cities in Austria, Germany, Denmark. His concerts at the Grosser Saal Musikverein of Vienna and the Lincoln Center of New York have won enormous successes. In August, 2000, he led again the Central Chinese National Orchestra to perform in the "Chinese Culture in America" Festival, appearing in musical centers including the Lincoln Center.
