This paper presents a self-adaptive load balancing algorithm, in which each peer creates a local load distribution view using a passive load statistic method and a local file requested view using file requested statistic method. When load imbalance exists in the system, the heavy loaded peer will make the logical links which point to itself to point to a light loaded peer in its local load distribution view, with the indegree of the heavy loaded peer decreasing and the indegree of the light loaded peer increasing, the load imbalance magnitude will decrease. When the request load of the heavy loaded peer is high, the peer will use its local file request view to get the popular file and cache the file to corresponding target peer.

提出一种自适应负载均衡方法，方法采用一种被动式结点负载统计方法生成局部负载视图；采用一种文件访问统计方法生成局部文件访问视图；当系统内结点负载存在差异，重载结点把指向自身的逻辑链路迁移至指向局部负载视图中的轻载结点，通过减小重载结点入度和增加轻载结点入度来减小结点间负载差异；当结点的请求负载较高时，通过局部文件访问视图计算需要缓存的热点文件及目标结点，降低承载热点文件的结点的请求负载。

And transform DAS from traditional central server architecture to peer-to-peer architecture. In addition, it provides the DAS developers software framework of the generic DAS based on peer-to-peer to develop a specific DAS. First, This thesis analyses all kinds of instances of DAS and remote monitoring systems, for example SCADA of power engineering; Secondly, Analyses various data acquisition standard, Including OPC, IVI, ODAS and DAIS RFP of OMG; Thirdly, analyses the current application State and character of Peer-to-Peer, content of UPnP and JXTA technology.

在这项研究工作中，首先分析当前不同类型的数据采集系统实例，包括电力调度SCADA系统，远程视频监控系统等一些数据采集与监控系统；第二，分析不同的数据采集标准，包括OPC，IVI，ODAS等数据采集标准，以及OMG的在工业系统中访问数据的标准界面DAIS RFP；第三，分析当前对等网络技术的应用现状和应用特点，并详细剖析UPnP和JXTA技术的技术内涵；第四，在对数据采集系统和对等网络技术的分析基础上，使用OMG的UML建模将通用数据采集系统规格化，建立基于对等网络的通用数据采集系统规格化的概念模型和基于角色的使用案例模型；第五，在通用数据采集系统规格化基础上，提出几个关键软件设计模式构造基于对等网络的数据采集系统软件框架；最后使用电力系统的应用开发实例来验证通用数据采集系统软件框架的可行性。

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.

纳米珍珠层/消旋聚乳酸复合人工骨与微米珍珠层/消旋聚乳酸复合人工骨分别与成骨细胞共培养后，其各时间点CCK-8法检测值与空白对照无显著差异(P＞0.05)，成骨细胞均在第5天达到增殖高峰期；培养7天后，实验组细胞蛋白含量高于对照组及空白组(P＜0.05)，后两者之间则无显著差异P＞0.05碱性磷酸酶活性在三组间均无显著差异(P＞0.05电镜下可见成骨细胞在两种人工骨上都有良好生长贴附能力。4.X-ray显示两种粉体在大鼠股骨骨洞植入第2周时都开始出现了降解，第4周时更为明显，纳米珍珠层粉较之微米珍珠层粉降解更快，而空白对照组骨洞阴影仍可见，至8周时，则所有组骨洞均己闭合修复，X-ray下已不可见原钻孔痕迹，恢复正常骨质密度；硬组织磨片四环素荧光双标记结果显示纳米珍珠层粉植入组较其余两组在骨缺损区周围新骨生长速度更快，空白组速度最慢P＜0.05电镜观察及常规脱钙切片亦可见到纳米粉体降解较快；由以上两种原材料制得的纳米珍珠层/消旋聚乳酸复合人工骨与微米珍珠层/消旋聚乳酸复合人工骨在大鼠体内均与周围组织结合良好，无明显炎症反应。5.X-ray显示纳米珍珠层/消旋聚乳酸复合人工骨植入兔桡骨缺损区后其骨愈合速度较对照组微米珍珠层/消旋聚乳酸复合人工骨植入的快，至植入术后24周，实验组骨缺损区接近正常骨密度，对照组骨缺损区密度较低，空白组则呈现骨不连状态；骨密度测量结果显示术后8周、16周、24周实验组的骨密度值高于对照组(P＜0.05，24周实验组的骨密度值与术前所测得的正常值无显著性差异P＞0.05动物取材大体所见均显示组织相容性良好，骨组织逐渐由植入材料两端向中央生长；常规切片HE染色及硬组织磨片Stevenel\'s blue/Van Geison\'s picro-fuchsin联合染色均可见实验组骨缺损区长势优于对照组，至术后24周，实验组骨髓腔与材料已呈相交通状；硬组织磨片荧光显微镜下观察，两组材料在术后8周处于骨生长最快速时期，16周时速度开始减慢，术后4、8、16周时实验组的新骨生长速度均较对照组的快
