1)  harmful carbon deposition
有害碳沉积
2)  hadmful carbon deposition
有害的碳沉积
3)  harmless carbon desposition
无害的碳沉积
4)  sediment related disaster

5)  marine organic carbon-rich sediments
海相富有机碳沉积
1.
Based on the previous discussion about geological setting and major controlling factors on the marine organic carbon-rich accumulation,this paper proposes that both high primary productivity(PP) and oceanic anoxic events(OAE) controlled the wide distribution of marine organic carbon-rich sediments in the mid-Cretaceous.
白垩纪中期(约125~88Ma)海相富有机碳沉积广泛发育于全球各主要洋盆和沉降区,是许多大油田的重要烃源岩。
6)  carbon deposition
碳沉积
1.
Simulation of carbon deposition conditions in a methane or acetylene flame based on mechanisms of chemical transport reaction;
基于化学传递反应模拟甲烷和乙炔燃焰中碳沉积的条件
2.
The effect of carbon deposition condition on gas permeability and selectivity through the membrane was investigated.
以一定浓度的酚醛树脂溶液对炭膜基板进行碳沉积处理,考察碳沉积条件对所制备的分子筛炭膜气体分离性能的影响。
3.
The results showed that when NTA was treated in CO at high temperature,the carbon doping in product TiO2 did not appear,only carbon deposition on TiO2 appeared;the BET areas of the products decreased markedly with the increase of treating temperature;The transformation temperature from anatase to rutile for TiO2 obtained by CO treatment was much lower than that obtained by air treatment.
结果表明:NTA经CO高温处理后,样品未发生C掺杂,只有碳沉积发生;随着处理温度的升高,样品的比表面积大幅下降,与NTA在空气中焙烧处理相比,由锐钛矿向金红石TiO2转变的温度提前;CO处理后产物对C3H6均未表现出可见光催化性能,但具有紫外光催化活性,随着在CO气氛中处理温度的升高,紫外光催化活性降低。
补充资料:化学气相沉积碳纤维
分子式:
CAS号:

性质:又称化学气相沉积碳纤维。指特定混合气在高温下热解沉积在催化剂微粒上成长成碳纤维。直径几微米,强度高达其理论值的1/4,模量高达1000GPa,电阻率0.8~1.5×10-4Ω·cm,抗氧化和耐腐蚀性优良。制法是将碳氢化合物的蒸气与铁、镍、硫及其氧化物或盐类微粒等催化剂源和氢氧接触,在1100℃下热解使碳沉积并在催化剂上成长,再经石墨化处理而得,也可制成弹簧状。用于先进复合材料的增强剂和弹簧等。
