The distributed system with the framework is strictly divided into five layers from the bottom to the top : data layer , data integration layer , transaction logic layer , interface control layer and user interface layer 本文提出并实现的应用框架将分布式系统自底向上严格地分为五层：数据层、数据集成层、业务逻辑层、界面控制层和客户界面层。
One possible scenario for developing a distributed application is to create one tier at a time , perhaps beginning with the data layer , then moving to the middle - tier business - rule object , and finally creating the user interface 开发分布式应用程序的一个可能的方案是一次创建一层，可能是从数据层开始，然后移到中间层业务规则对象，最后创建用户界面层。
Moreover , thermal shock behavior of 3d - c / sic was distinctly superior to that of recrystallization sic , and when the deposition time of pyrocarbon was 20h , 3d - c / sic possessed the longest thermal shock life 3d - c sic复合材料的抗热震性能明显优于重结晶sic陶瓷材料；三种界面层的3d - c sic中，以热解碳沉积时间为20小时获得的界面层复合材料热震寿命最长。
For the nitrogen - implanted samples , the initiation of crack is greatly delayed , and crack spacing interval is small . the samples prepared by pecvd and piii technologies have been investigated using homemade gas permeation tester . the excellent barrier 而注入件相对沉积件而言,由于没有明显的界面层,而表现为改性层裂纹间距小,但没有完全开裂,具有优良的耐失效性能。
Within the standard web application model that consists of user interface , business logic , and data storage tiers , the open source community and ibm both offer an application to provide the services to support each specific role 在这个由用户界面层、业务逻辑层和数据存储层组成的标准应用程序模型中，开放源代码组织和ibm都提供了应用程序以提供服务来支持每一个特定角色：
In order to suppress the formation of silicide interfacial layer , a zro2 thin film was deposited as a barrier layer between hfo2 and si . the samples with barrier layer exhibited better leakage and c - v character than the directly deposited ones 作为阻挡层抑制hf和a的互扩散反应，减小了界面层厚度，并提高了界面层的氧化效率，与无阻档层的样品相比电学性能得到了显著的提高。
