烷基裂解 的英文怎麼說
中文拼音 [wánjīlièjiě]
烷基裂解
英文
alkyl cleavage-
After the decarboxylation process the alkane produced can be degraded or "cracked" =to lower carbon number alkanes.
脫羧基作用后，所形成的烷烴能被降解或「裂解」成低碳數烷烴。P / a, fl / py ratios and ring numbers of pahs were used to assess the origins of the pollutants, suggesting possible sources such as combustion of coal, wood and petroleum pyrolysis
P / a 、 fl / py比值、 pahs環數以及烷基化pahs表明膠州灣表層沉積物中pahs幾乎全部由人類活動產生，來源為煤炭燃燒、木材燃燒、石油類高溫裂解及油類污染。Focusing on serious damage of carbon fibers in ceramic matrix composites ( cmcs ) prepared by precursor infiltration pyrolysis ( pip ), and with emphasis on carbon fiber reinforced silicon carbide composites ( cf / sic ) derived from polycarbosilane ( pcs ), the influences of raw materials ( including carbon fibers and precursors, etc. ) and preparing conditions on carbon fiber damage during the preparation of cf / sic composites were investigated systemically. pyrolysis process, fiber - matrix interface and carbon fiber damage process were observed by sem, tem, ir, xrd, xps and tq etc. the characterization method of carbon fiber damage degree was established and the models for carbon fiber damage mechanism were also established. the carbon fiber coatings and unidirectional cf / sic composites with coated carbon fibers were prepared and studied
本文針對先驅體浸漬裂解工藝制備陶瓷基復合材料過程中碳纖維損傷嚴重的問題，以聚碳硅烷（ pcs ）制備cf / sic復合材料為重點，採用sem 、 tem 、 ir 、 xrd 、 xps 、 tg等表徵手段，分析了先驅體裂解過程、纖維基體界面和碳纖維損傷過程，系統地研究了原料（碳纖維、先驅體等）和制備工藝條件等在cf / sic復合材料制備過程中對碳纖維損傷的影響，建立了碳纖維損傷程度的表徵方法和損傷機理模型，制備了纖維表面塗層並利用塗層碳纖維制備了單向cf / sic復合材料。
