查询词典 thereby

We transformed RMgBr into R-Ti derivatives with the production of byproduct MgBrO~(i-Pr at the same time, but we didn\'t need romove the Mg salt by centrifugation or chelating reagents, for bis[2-(N,N-dimethylamino)ethyl] ether could chelate with Mg atom and thereby reduced the Louis acidity of Mg salt, so we used R-Ti derivatives produced in situ to alkylate the aldehydes induced by BINOL-Ti complexes..

我们通过利用TiO~(i-Pr_4使格氏试剂转化成烷基钛，同时产生具有亲核加成促进作用的副产物MgBrO~(i-Pr，由于BDMAEE能与MgBrO~(i--Pr络合降低其路易酸活性，所以不需要离心或者借助络合试剂完全除去镁盐，而使用原位生成的烷基钛在BINOL-Ti诱导下对醛进行不对称加成。

According to Cunningham, I chose wiki-wiki as an alliterative substitute for 'quick' and thereby avoided naming this stuff quick-web.

"据坎宁安说："我选择的wiki wiki链接作为alliterative代替'快速'，从而避免命名这个东西快速的网络。

During the absorption process, each alpha particle will collide with one or more atoms in the conductor knocking electrons from their orbits and imparting some kinetic energy to the electrons in the conductor thereby increasing its conductivity.

" "在吸收过程，每个α粒子碰撞将与一个或多个原子在导体敲开电子从它们的轨道，并传授了一些动能，以电子在导体从而增加其导电性。

If we can ameliorate the product, we can sell higher price thereby we can obtain higher profi

如果我们能改进产品，就可以卖更高的价格，从而获得更高的利润。

Catalysts are made by impregnating a porous transition alumina support with an aqueous solution of a copper ammine carbonate complex, draining off any excess of the impregnating solution, and then heating the impregnated support to a temperature above 80 DEG C to decompose the complex thereby depositing a basic copper carbonate compound on the surfaces of the pores of the transition alumina support.

用作例如催化剂的铜／氧化铝组合物，通过用碳酸铜氨配合物的水溶液浸渍一种多孔氧化铝载体，排出任何多余的浸渍液，然后加热所浸渍的载体到80℃以上的温度来分解所述配合物，从而在所述过渡型氧化铝载体的气孔表面沉积一种碱式碳酸铜来制备。

The results of IR and XRD for ground cement components show that grinding aids accelerate breakage of chemical bonds especially of Si—O bond in C〓S mineral, enhance crystal lattice distortion, crystal defect and amorphism, thereby enhancing activity of ground materials.

助磨剂作用下磨细物料的XRD、IR分析结果表明：助磨剂加剧了物料的晶格畸变、晶格缺陷及无定形化，加速了物料结构中化学键的破坏，尤其是C〓S矿物中Si—O键的断裂，从而增加物料的反应活性。

These anaesthetics block sodium channels and thereby the excitability of all neurons, not just sensory neurons.

它们的亲油性使它们能进入几乎任何神经元，在那里，它们会不加甄别地阻断细胞膜中的钠通道。

It is capable of reliable transmission of feeble analogue and digital signal in harsh working environment and has excellent interference immunity to magnetic field and static and stable electric properties, barely affected by either high or low temperature , chemical solvents or corrosive gases , thereby providing accurate transmission of signal data and guarantee of safe operation of the control system .
