I was founded in 2005, is a professional Chemical Industry Co., Ltd, Main BF3 acetonitrile complex, boron trifluoride diethyl ether complex, boron trifluoride DMC complex and Inorganic chemical raw materials, pharmaceutical intermediates.

我公司成立于2005年，是一家专业的化工实业有限公司，主营三氟化硼乙睛络合物、三氟化硼乙醚络合物、三氟化硼碳酸二甲酯络合物及无机化工原料、医药中间体。

It is used to some extent in pharmaceutical industry (used as special catalyst to produce antibiotics) and chemical industry, esp. in production of cephalosporin (whose effect is better than boron trifluoride ethyl ether complex compound), and also used for most advanced science, such as abstraction of fuel with high energy and of isotope B10 as well as chemical reagent.

在制药工业(在医药上作为生产抗生素的专用催化剂)、化学工业等行业中都有不同程度的使用，尤其在头孢抗菌药类，效果优于三氟化硼乙醚络合物，亦用于尖端科学，如高能燃料的提取及提取同位素B10，也可用作化学试剂

The catalysts such as tetraphenyl tin,aluminium isopropoxide and boron trifluoride etherate complex were used to catalyze the copolymerization.In addition,the copolyester can be given by copolycondensation after monomers were hydrolyzed by phosphoric acid.Boron trifluoride etherate complex was chosen as the catalyst because the catalytic activity was the best among the catalysts.

由于γ-戊内酯为五元环结构，难以进行开环聚合，因此分别考察了四苯基锡、异丙醇铝、三氟化硼乙醚络合物等催化剂，以及以磷酸为催化剂的水解缩聚反应，结果发现三氟化硼乙醚络合物的催化活性最高，因此选择三氟化硼乙醚为本体开环聚合的催化剂。

Using butanediol as initiator, boron-trifluoride etherate as catalyst, 3-azidomethyl-3-methyloxetane homopolymer was synthesized by the cationic polymerization of 3-azidomethyl-3-methyloxetane which was carried out in dichlorometane.

以1，4-丁二醇为引发剂，以三氟化硼乙醚络合物为催化剂，以3-叠氮甲基－3-甲基氧丁环为单体，以CH2Cl2为溶剂，按阳离子开环聚合机理，合成了含能粘合剂3-叠氮甲基－3-甲基氧丁环均聚物。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
