stereospecificity 中文意思是什麼
-
Whole cell c2d2 reduction by all four mutants comparing to wild type and ni / v mutant was also detected. the result showed that only single a - gln194 substitution did not perturb the stereospecificity of protonation of c2d2. the above comparing results indicate that in mofe protein ( 1 ) a a - gln190 site and its association with homocitrate are important for the transfer of electron / proton to femoco, while a - his194 site and the homocitrate are independent in h2 evolution
對四個突變株細胞的c _ 2d _ 2還原特性及還原產物中反式-順式- 1 ， 2 -二氘代乙炔的比例進行了測定並與野生型及nifv突變株相比較，結果表明只有- gln ~ （ 194 ）替換不影響c _ 2d _ 2還原產物中反式-順式- 1 ， 2 -二氘代乙炔的比例，即未改變固氮酶還原c _ 2h _ 2加氫的立體構型的專一性。 -
The stereospecificity of the thermal cleavage of pyrazolines is lacking although stereoselectivity does exist.
二氫吡唑熱解雖然有立體選擇性，但沒有立體定向性。 -
The results show that, with the higher the polymerization temperature, the higher activity and stereospecificity, but lower hydrogen response with a - catalyst can be obtained, and the higher activity, stereospecificity and hydrogen response with b - catalyst can be obtained
結果表明，隨著聚合反應溫度的提高，聚丙烯催化劑的活性增加，定向性提高， a催化劑的氫調敏感性變差，而b催化劑的氫調敏感性增強。
