-6°卧床模拟失重对T淋巴细胞的影响及内分泌调节机制的研究

本文研究了-6°卧床模拟失重对T淋巴细胞受到有丝分裂原刺激后增殖能力和外周血总T淋巴细胞亚群(CD3+T细胞)、辅助/炎性T细胞亚群(CD4+T细胞)、杀伤T细胞亚群(CD8+T细胞)、及表达CD25分子细胞数的影响,同时观察生长激素、促肾上腺皮质激素、皮质激素的改变,来探讨免疫功能的变化与内分泌系统改变的关系.结果表明,模拟失重造成的免疫功能下降与内分泌系统紊乱有关.      

A Distributed Intelligence Automatic Test System for PATRIOT

An automatic test system supporting high volume production testing of diverse state-of-the-art electronic assemblies is described. The test complex consists of a centralized computer system communicating to a network of satellite stations, each structured as "Intelligent Test Centers" dedicated to a particular family of assemblies (e.g., analog, digital, microwave). Allocation of resources and tasks have been distributed for optimum efficiency of production testing. This paper describes the organization and characteristics of the test system. Test center operation is explained with emphasis given to unique man-machine interactive features designed for on-line generation, examination, and maintenance of Unit-Under-Test (UUT) programs. Details are presented of the test language, RATEL, used for UUT programming. Other aspects that are discussed include test data and UUT program characteristics.
