coarsing
解釋
粗化-
The result reveales that the decrease of sediment transportation of the upper reaches results in riverbed scouring and coarsing on yidu reach ; the upper and lower shallow regions in shahong are separately deepened and broadened, while the thalweg in shihong is lowered, and nanyangqi is scoured and draw back … all the above may cause variation of the distribution pattern
結果表明，來沙量減少使宜都水道沖刷，沙泓上淺區沖刷下切，而下淺區以沖灘為主，石泓深泓沖刷下降，南陽磧沖刷縮小，分流格局有發生變化的趨勢。 -
( 1 ) first, metallizing abs plastics surface by chemical coarsing, metal ion absorption, metal ion reducing and chemical copper - plating. then, the copper - coating was thickened by electroplating in order to improve adhesion between following - coating and plastics matrix, and nickel was preplating. finally, ni - sic composite was plated
（ 1 ）通過反復實驗，確定工藝流程：首先通過粗化、敏化、活化和化學鍍銅，使塑料表面金屬化，再電鍍銅加厚銅鍍層，增強后續鍍層與塑料基體的結合力，然後預鍍鎳，最後電鍍ni ? sic復合鍍層。 -
Abstract : in light of thicker grain and smaller viscosity of debris flow, a segmented simulation of the debris flow with flume is presented. for the first time. more difficult resistance similarity is brought about by geometric rate without excessive coarsing and discontinuous similarity of sand grain composition in model is eliminated with different grain scale. on this basis the density similarity and sand conveying similarity are achived. the method presented is verified through a model test case
文摘:針對水石流顆粒粗，粘性小的特點，提出了利用水槽進行分段模擬水石流的設想，首次通過幾何變率解決難度較大的阻力相似問題，改變了以往過度加糙的方式;通過變粒徑比尺的方法消除了模型沙級配不連續相似的問題，較好地實現了固體物質級配相似，達到了泥石流的密度相似和輸沙相似.通過水槽概化模型試驗實例，對本方法進行了驗證 -
The plastics matrix might be exposed with under - coarsing. the cracks might appear on the coating with over - coarsing. ( 2 ) the thickness of copper coating should be over 5m for preventing coating wrinkle
（ 2 ）電鍍銅時銅鍍層必須具有一定的厚度，不應低於5林m ，防止鍍鎳后鍍層起皺，從而影響鍍層與基體的結合力。 -
To obtain light radar wave absorbing materials, the electroless nickel plating on hollow glass beads and mica was studied. after pretreatment of coarsing, sensitivzed, activation, and reduction, the hollow glass beads and mica powders were plated with nickel
研究了在空心微珠和雲母上的化學鍍鎳，嘗試在微珠上鍍鎳制備輕質雷達吸波材料，發現空心微珠壁太薄，經攪拌和加熱后破碎太多，但從形貌上看已經實現了表面化學鍍鎳。
