鏡質絲煤 例句

1. Bituminous brown coal
   瀝青 質 褐 煤
2. The expansion agents can only make up the shrinkage to some extent, and the compensation effects would be reduced when the retardener and fly - ash are used. the expansion agents are not panaceas to avoid the shrinkage cracking as expansion can also reduce the concrete soundness. under bad curing condition, the polypropylene fibrillated film fiber can improve concrete ' s anti - crarking property, while the nominal steels have very unobvious effects. to reduce the concrete shrinkage thus avoid the cracking, the former factors must all be taken into account in concrete proportion design to develop sound concrete
   研究結果表明，水泥的品種和用量是影響混凝土收縮值的主要因素之一，當混凝土中水泥用量超過470kg / m ~ 3時，混凝土的收縮值超過400 10 ~ （ - 6 ） ，在約束狀態下存在高開裂風險；採用細砂使混凝土單位用水量顯著提高，收縮值也大幅增加；優 質 粉 煤 灰總體上能抑制混凝土的收縮，以超量方式摻入其抑制作用更加明顯，但粉 煤 灰混凝土早期的粘聚性較差，應注意養護，以免失水產生龜裂；早強減水劑和緩凝減水劑都會使混凝土收縮值增加；膨脹劑只能補償混凝土部分收縮，同時受緩凝劑和粉 煤 灰的抑制，而且膨脹使混凝土的體積安定性增加了不確定因素，膨脹劑不是解決混凝土收縮裂縫的良方。
3. Fouriertransformation infro - red microspectroscopy micro - ftir technique was used to investigate the chemical compositions and structures of cutinite, vitrinite and fusinite from jurassic coals in tarim basin at different temperatures. the results show that the chemical structure of cutinite is mainly composed of long aliphatic - side chain with minor amounts of aromatic compounds. vitrinite is mostly composed of aromatic compounds, in addition to large amount of short aliphatic - side chain compounds. whereas fusinite are dominant by aromatic structure. the study indicates that cutinite is one of the best oil source - rocks, with the higher hydrocarbon - generation potential ; vitrinite is one of better gas source - rocks, and has medium hydrocarbon - generating potential ; fusinite has little hydrocarbon - generating potential. in addition, the components of aliphatic structures of cutinite, vitrinite and fusinite decrease, the aromatics are enriched and condensation of aromatic structure increases with increasing the temperature, and along with the rise of temperatures, the intensity of aliphatic structure and heteroatomic compounds decrease obviously, however the aromatic structure changes a little
   應用顯微紅外光譜技術，對塔里木盆地侏羅紀 煤 中有代表性的3種組分角 質 體 鏡 質 體 絲 質 體在不同熱模擬溫度下的結構組成變化特徵進行了研究，結果表明：角 質 體結構組成中含有較豐富的長鏈脂族結構，而芳香結構和含氧官能團的含量則相對較少與此相反， 絲 質 體結構組成中芳香烴占絕對優勢，而脂族結構含量則很少 鏡 質 體結構組成介於角 質 體和 絲 質 體之間，含有較多的短鏈脂族結構和芳香結構。
4. The regularity is obvious about the correspondence between mean maximum reflectance of vitrinite and classification of coals
   但總的來說，煙 煤 鏡 質 組反射率與 煤 種之間的關系規律性明顯。
5. Formula s founded on factors of water - binder and fly ash content is feasible. at the same time ， the effects of fly ash quality ( grade ， fly ash from huaneng fuzhou power plant ), content of chemical admixture etc al, are investigated
   本文利用環境掃描電子顯微 鏡 （ esem ）技術，研究粉 煤 灰對各齡期（ 3d 、 7d 、 28d 、 60d ）混凝土細觀結構的影響和不同品 質 粉 煤 灰對混凝土細觀結構的影響。
