手

The teacher was surprised and puzzled by the picture that Jack handed in— a hand, a simple childishly drawn hand!

当老师看到杰克交上来的画时，却吃了一惊，他画的是一只手，一只简单的、出自孩子之手的手。

In this reaction the matching of planar chirality and central chirality is also important.

在该反应中平面手性和中心手性的匹配也是重要的，平面手性仍然决定了产物的绝对构型。

The invention relates to a chirality sensor based on bovine serum albumin and the manufacture method.

不同的手性异构体在生物体内的生物活性，药理作用，代谢过程等有着明显的差别，因此发展简单，准确，快速的手性识别方法成为近年来手性分析的主要方向。

The sensor could high effectively test chirality amino acid and drugs.

本发明的手性传感器能高效地应用于检测手性氨基酸和手性药物。

And among substrates including 2'-chloroacetophenone, 3'-chloroacetophenone, 4'-chloroacetophenone and 3-chloropropiophenone, the highest productivity of the reduced product with S. cerevisiae B5 was observed for 2'-chloroacetophenone.

许多研究者都在致力于研究和开发产物转化率高、手性选择性好的手性化合物合成路线，其中生物转化法由于其温和的反应条件及高度的手性选择性而受到人们的青睐。

In Chapter 2, enantioseparations of four pairs of neutral and poorly water-soluble organophosphorus pesticides enantiomers were achieved by using natural chiral surfactant sodium cholate either with sodium dodecyl sulphate or with γ-cyclodextrin in nonaqueous solvent or aqueous-organic solvent systems.

第二章在非水介质或水相/有机介质中，或将天然表面活性剂胆酸钠与阴离子表面活性剂十二烷基硫酸钠构成混合手性胶束，或将胆酸钠与γ-环糊精构成二元手性协同体系，用于中性疏水有机磷农药对映体的手性拆分。

In the asymmetric hydrogenation of ethyl pyruvate catalyzed by 0 5% Rh/PVP TiO 2, the chiral modifier cinchonidine not only induces the enantioselectivity, but also accelerates the reaction rate greatly.

研究了辛可尼定作手性修饰剂修饰的负载型纳米铑簇合物催化剂(0 5 %Rh/PVP TiO2 )催化丙酮酸乙酯不对称氢化反应，在该反应中手性修饰剂辛可尼定不仅具有对产物生成的手性诱导作用，而且对反应具有明显加速作用；在优化反应条件后，反应的TOF和对映选择性分别可以达到 5 8 0min-1和

First, according to the model chart ruler, opens cutting the gate hole two, the decision opens the door the direction, changes the slanting tongue direction three, inside and outside the adjustment the hand direction (if: The symmetry holds the hand, does not need to exchange holds about the hand adjustment then), holds the hand like left and right AND gate to open the direction asymmetrically to be opposite, invites you: A, takes down the circlip and the edges and corners with the special-purpose circlip pliers.

一、按样板图尺，开凿门孔二、决定开门方向，改为斜舌方向三、调整内外把手方向（若：对称执手，无需调换执手调整左右即可），非对称执手如左、右与门开启方向相反，请您： A、用专用卡簧钳取下卡簧和棱角。

In addition to studying handedness in humans, I have also studied hand usage in mountain gorillas as well as chimpanzees, red colobus monkeys, redtail monkeys and grey-cheeked mangabeys.

除了研究人类的"利手"外，我也研究过山地大猩猩使用手的情况，还研究了黑猩猩、红疣猴、红尾猴以及灰颊候使用手的情况。

When contacting with the virtual object, the contact force can be calculated and shown in the graphic interface.

此系统中，操作者通过主手控制虚拟环境中的从手与虚拟物体相作用，虚拟环境中的接触情况如碰撞响应、形变在图形界面仿真，虚拟力通过主手装置表达。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
