The ingredients of the coat mainly include phosphate, epoxy resin, an amine solidified agent and water. Through the adjustment of ingredients, superior adhesiveness, corrosion-resistance performance, welding performance and stamping preformance have been obtained. Thus ,the non-oriented silicon steel sheets with the above Cr-free coat have been used successfully in the fields of compressors ,transformers, and small and medium motors.展开更多

Ultrastructurally these microorganisms are usually pleomorphic and variable in morphology and size, and appear in several cell types such as small spherical body, rod-shaped bodies and longer filament-shaped body. They lack a cell wall. These observations revealed that these types of the prokaryote showed some characteristics of a mycoplasma-like organism （MLO）. MLO reproduced in two ways： binary fission and budding. The results of isolation and purification showed that a large number of MLOs existed in the tissues of diseased scallops. The results of experimental infection revealed that the MLO is pathogenic to the scallop Argopecten irradians.展开更多
