In this thesis , the author at first analyses the component gis and the tide of realizing webgis as a component system , then discusses the difficulties those programmers meet when using arcxml directly . after clarifying the advantages of shielding arcxml and packing gis general functions , the thesis makes the decision of developing arcims general components to attain the aim of simplifying the developing process of arcims application system and shortening developing period 为了简化arcims应用系统的开发过程,缩短系统开发周期,论文深入讨论了arcxml为二次开发人员开发gis功能带来的复杂度,指出利用构件技术屏蔽arcxml复杂性、封装地图通用功能是简化arcims地图功能开发的有效手段,提出了开发arcims高级通用构件的方案。
Then , kept on those principles , a distributed component system application management model ccs - mfma is presented and implemented , which is very suitable for distributed component management , and could make the whole system be manageable in deferent levels , for example , manageable component , manageable container and component server . 3 针对大型分布式系统的应用管理需求,提出并实现了面向分布构件计算特征的系统应用管理模型ccs - m _ fm _ a ,通过增加相关的应用管理设施,使得整个分布式构件系统能够从构件、容器、服务器等不同层次实施系统应用管理的任务; 3
Generally speaking , if the fitted results are not satisfactory for binary systems , the prediction is also bad for multi - component systems that include the binary ones , and the more the temperatures at which the multi - component system is predicted are close to that of the binary systems , the better the predicted results with wilson equation 若对二元系的拟合效果较差,则对包含该二元系的多元系的预测效果也不是很理想。同时,对多元系的预测还受到温度的影响,一般来说,多元系的预测温度与用于拟合参数的二元系的温度越接近,则wilson方程的预测效果越好。
The doping of in of cdznte wafers was also achieved through annealing by adding in in the annealing sources . the specific parameters were established according to the thermodynamic principles of multi - component system . the properties of the wafers , including composition distribution , optical and electronical properties , were tested before and after annealing 将退火与掺杂过程结合起来,根据多组分热力学原理制定了退火掺杂的工艺参数,对比研究了掺杂退火前后成分分布、 in掺入量、红外透过率以及电阻率的变化情况。
