2 What is the maximum allowable stress for CJP groove weld meta l splicing two ASTM A-36 steel non-redundant members of equal thickness and width, subject to loading of 2×106 life time stress reversals, assuming the weld reinforcement remains and all such joints are to be radiographed ?

对於连续两个同样厚度和宽度的 ASTM A-36钢的非超静定焊接件，假定保持焊缝加强高并所有如此接头都要进行射线探伤，在承受2×106连续应力交变载荷下完全熔透坡口焊缝金属的最大允许应力是多少？

An increasingly important requirement for software systems is the capability to evolve dynamically according to the changes of computing environment and users' need during runtime. In this paper, a dynamic software architecture oriented approach is proposed to support online evolution. Notably, architecture information is reified as explicit and manipulable entities to organize a runtime architecture meta-model, which is causally connected to software implementation and specification.

为适应计算环境和用户需求在系统运行期间的变化，满足软件系统进行动态演化的需求，提出面向动态软件体系结构的在线演化方法，设计并实现了一种运行时刻的软件体系结构元模型，将原先运行时刻不可见的体系结构设计信息具体化为显式的体系结构实体，并与系统实现及系统规约之间保持因果关联。

Being a scientific methodology the meta-synthesis has been synthesized the advantages of computer network, data syncretizing, knowledge, information and the intelligent of experts.

作为科学的方法论，综合集成方法论综合了计算机网络技术、数据融合技术、知识与信息及专家群体智能的各方面优势，其应用在研究方式和工作方式上都突破了传统还原论思想的束缚。

Tvmet - This Tiny Vector and Matrix template library uses Meta Templates and Expression Templates to evaluate results at compile time, thus making it fast for low-end systems. Temporaries are avoided because of this.

Tiny Vector and Matrix模板库使用Meta Templates 和Expression Templates在编译时评价结果，这使得它对低端用户来说速度更快，因此也避免了临时文件。

To avoid the collision accidents of ships at sea, with the universalizing and application of computer, and the development and maturity of the technology of Expert System and Artificial Intelligent, this paper developed an intelligent collision avoidance expert system for navigation. The main research work centers on several aspects, which will be represented as below:By the navigation rules" understanding and analyzing, and by the navigation experience and navigation samples" collecting and trimming, we put forth and build a multi-unit and layering KB systematic structure, and implement the KBM. According to features of different knowledge, we adopt multifarious KR, such as: frame KR, production rule KR, procedure KR. We also build a multi-inference system, which based on analog inference, forward illation inference, conversion inference and meta-rule inference. At the same time, we develop each reasoning algorithm. For some problems in collision avoidance region during the building of the expert system, we put forth and build a set of models to solve them using neural network technology.

为了避免船舶间碰撞事故的发生，结合计算机技术在各类船舶中的普及与应用、专家系统技术及人工智能技术的发展、成熟，本文研制、开发了一种具有一定智能的航海避碰专家系统，主要内容包括以下几个方面：通过对航海规则的理解与分析，对航海经验、航海实例的搜集、整理，提出并建立起了航海避碰专家系统的多元分层知识库体系结构，并实现了知识库的管理；根据不同知识的特点，分别采用了框架、产生式规则、过程等多种知识表示方法；提出了一种基于类比推理、正向演绎推理、换位推理及元级推理等的多种推理机制，并建立起了相应的推理算法；引入神经网络技术，针对在建立专家系统过程中所遇到的有关避碰领域内的一些难题，提出并建立了相应解决问题的模型，其中包括：船舶类型的识别，会遇态势的分类及避碰危险的评估。

Objective To conduct a meta-analysis of RCT studies of the association between PPD skin test and pulmonary tuberculosis. To assess the diagnostic value of PPD skin test in patients with the pulmonary tuberculosis.

目的 通过对国内有关继发性肺结核与PPD皮试联系的病例对照研究结果进行荟萃分析，获得综合的结论，以期对PPD皮试作为诊断实验在诊断继发性肺结核中的意义作出评价。

Meanwhile, as the growth of arc, the lost of arc heat quality becomes larger, so the heat quality which is used to fuse base meta l and weld stick decreases, the weld width and weld reinforcement decreases comparatively.

同时，电弧增长后，电弧的热量损失加大，所以用来熔化母材和焊丝的热量减少，相对焊缝宽度和余高就略有减少。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.
