查询词典 alternate function

Hyphal growth rate method was used to determine the inhibitory activities of chitooligosancharide against the pathogenic fungus of tobacco brown spot, Alternaria alternate Keissler, in the laboratory, and tobacco plants were applied with COS and its combinations like COS + Trichoderma + chitin with 5 treatments to control the disease under conditions of pot culture and inoculation in the greenhouse. Activities of 4 defensive enzymes, superoxide dismutase, polyphenol oxidase, peroxidase and chitinase, in tobacco plants were determined systematically at the same time within 10 days after application of COS and inoculation with the pathogenic fungus.

Disposable stainless steel needles (0.2 mm × 40 mm, Seirin Co Ltd) were inserted into the muscle to a depth of 10 mm using the 'sparrow pecking' acupuncture technique (alternate pushing and pulling of the needle) by acupuncturists who had four years of acupuncture training and three to eight years of clinical experience.

A series of erosion-corrosion test has been done to J55 steel under the influence of current of gas-liquid phase by indoor self-made devices, and the corrosion mechanism of current of gas-liquid phase to oil pipe's inner surface has been got. The results show that oil pipe's inner surface will be corroded fleetly by liquid medium and corrosion products will form on it. But at the same time, the corrosion products or protective layer will be removed from the inner surface of steel pipes under the alternate impact of high speed gas and liquid flow, and on this bare steel surface corrosion film will form again and be removed again. Thus, by these ways the corrosion is exacerbated. Surface erosion-corrosion failure comes into being with the circulation of this process going on.

本文主要在气液两相流作用条件下，通过室内自制装置，对管材钢J55做了系列冲刷-腐蚀试验，结果表明，气液两相流对钢管内表面冲刷－腐蚀的机理是钢管内表面会受到液体介质的快速腐蚀，生成腐蚀产物，同时钢管金属表面不断被具有高流速的气液相交替地冲击，不断地从金属表面脱去保护膜或腐蚀产物，裸露的钢表面又会被介质快速腐蚀形成腐蚀膜后，再被两相流冲掉，如此反复，造成管内金属表面膜的连续破坏，使腐蚀加剧，最终导致钢铁表面的冲刷腐蚀失效。
