新型络合剂在多种工序中的应用,可以为单道工序甚至整个生产过程节约大量成本,加速生产循环,省去部分加工步骤,同时还提高了不稳定配方的生产可靠性。极简化的操作水平也可以节约大量能源。现代技术和设计应将络合剂作为重要的过程控制参数,因为这关系到整个工艺的成败, 相似文献

This article reports on the author's experience of being a member of the Michigan State University group sent to Viet Nam to give technical aid to the government of that new country in 1955. While meeting with one government official, the question arose on whether the team could give a test in order to make sure that only students who could benefit from police training would be included in an in-service training class. What follows in the article is the creation of such a test. Emphasis is placed on the difficulty of translation, test administration, reconstruction, reliability, scoring, and so forth. The author notes that testing in another culture can have its surprises, but can be very useful in that culture. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

To determine the behavior of silicon carbide (SiC) against long rod impact a detailed study with experiments in the velocity range from 0.8 to 3 km/s at normal impact conditions was performed in recent years. Interest ranged from penetration performance of intact and pre-damaged SiC to interface defeat capability of SiC. Together with impact data in the hypervelocity regime this paper provides a comprehensive overview of the penetration dynamics of SiC over a wide velocity range and during different phases of the penetration process. 相似文献

Spread-spectrum signals that use spreading codes chosen to give a low probability of chip rate detection are examined. Pulse shaping and pseudorandom amplitude weighting are used to defeat the interceptor who uses a nonlinear circuit to generate a tone at the chip rate of the signal. The case of low input signal-to-noise ratio (SNR) is considered. Under this assumption, the detector output spectrum is found, and the output SNR is then used as a measure of detectability. The effect of signal pulse shape, i.e., band-limiting, on performance is studied. It is shown that a combination of band-limiting and correctly chosen amplitude weightings can, ideally, defeat any such circuit. The performance of a fourth-power envelope detector is analyzed with a combination of signal pulse shape and amplitude weighting. The amplitude distributions are binary, Gaussian, and quantized Gaussian.<> 相似文献

"The techniques of industrial psychology offer striking advantages not only to Africans at the employee level but to managements as well." The industrial psychology of Africa is mostly influenced by the British and French. Considerable American influence was apparent in South Africa and Liberia. Centers of industrial psychology in Union of South Africa, Ghana, Nigeria, Federation of the Rhodesias and Nyasaland, Kenya, Uganda, Sierra Leone, Liberia, "French" Africa, and Belgian Congo as well as other African countries are mentioned. "The development of industrial psychology in the various parts of Africa has generally followed closely upon the development of the educational system and of industry."
