蚀程度 meaning in English
degree of corrosion
Examples
- In newly - constructed stage , early stage and later stage of reclamation , the degree of erosion and the space - time characteristics of influence factors have been analyzed and compared by the evaluation index and model
运用评价指标和模型分析了排土场未复垦时期、复垦初期、复垦后期的土壤水蚀程度及影响因子的时空变化特征 - Aramid filaments are treated by a low - temperature plasma with different treatment times . the surface of filaments is observed by sem and the results show that the filament surface is smooth before the treatment and becomes more rough if filaments are treated for 6 minutes . in addition , it is found that the filament peels after 9 minutes of plasma treatment
本课题采用低温等离子体对芳纶纤维进行表面处理后，用sem观察纤维表面，发现未经等离子体处理的纤维表面比较光滑；等离子体处理6分钟后，纤维表面变得粗糙，产生很多微小的刻蚀坑；等离子体处理9分钟后，纤维表面受到的刻蚀程度明显增加，并产生表面剥离现象。 - The studies expressed that the tensile - strength declined with the growth of dose rate after the radiation treatment , and at the same time , the gel content had extreme value with the change of the dose rate . the surface of uhmwpe fibers showed some irregular micro - pits and dents after radiation treatment , narnely rough degree increasing . their number and deepness increased with increase of dose . and this phenomenon is the most obvious when the dose rate was 8 . 5kgy / s and the dose was 400kgy . at the same time some containing oxygen groups , including hydroxyl group , carbonyl group and carboxyl group , were introduced into the fiber surface which was exposed to the air
研究表明， uhmwpe纤维经电子束辐照处理后，纤维的拉伸断裂强度随剂量率的增加呈下降趋势，凝胶含量随着剂量率的变化存在极值。纤维表面出现了不规则的微裂纹和凹痕，随着剂量的增大，电子束对纤维表面的刻蚀程度增加，在本研究中以剂量为400kgy剂量率为8 . 5kgy s时刻蚀效应最为明显。同时，在空气中进行辐照时，纤维表面被引入了一些含氧基团，包括羟基、羰基和羧基。
