正氢

Different factors such as mole ratio of reactants, temperature and reaction time were studied by orthogonal test.

以硫酸氢钠为催化剂在高压釜中合成水杨酸乙酯，采用正交实验研究了醇酸摩尔比、温度、时间等因素对反应的影响。

The chemical potential as a function of the bulk pressure is presented, and its correctness is proved.

在此基础上，通过巨正则蒙特卡罗模拟，仔细地分析了化学势对模拟计算单壁碳纳米管储氢的影响。

With the single factor test and orthogonal test, the optimal culture media for HF3-04 strain producing agarase was decided as: agar 3‰, NH4NO31‰, Na2HPO4 0.5 mM, pH 8.0. The optimal fermentation conditions were inoculum size 3‰, 110ml medium in 250mL Erlenmeyer flask, rotation rate 150r∕min, culture time 48h,culture temperature 25℃.

通过正交试验确定其最佳培养基组成为琼胶3‰、硝酸铵1‰、磷酸氢二钠0.5mM、pH值8.0；该菌株的最佳培养条件为接种量1%、装液量为250ml三角瓶装入110ml发酵培养基、摇床转速150r∕min、培养温度25℃、培养时间48h。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
