双分子的

The geometry, electronic structures and electronic spectra of trans stilbene derivatives are systematically studied by PM3 and INDO/CI methods.

分子在强激光束作用下，能同时吸收两个光子的现象称为双光子吸收。

另一方面，在这种铝盐溶液中，三价铝离子是以铝水配合物的形态存在，配位水发生水解生成羟基配离子，其通过羟基桥联结，放出水分子，并逐级由单体配合成双核、三核以致形成多核羟基配合物。

In the aluminum solution ,the trivalence aluminum ion combines with water to form the coordination compound and then the coordination waters hydrolyze into hydroxide ions. The hydroxide ions can join up each other by the hydroxide ion bridges so that the double cores, three cores and multiple cores coordination compounds are formed.

另一方面，在这种铝盐溶液中，三价铝离子是以铝水配合物的形态存在，配位水发生水解生成羟基配离子，其通过羟基桥联结，放出水分子，并逐级由单体配合成双核、三核以致形成多核羟基配合物。

Nonlinear optical organic materials have more advantages than inorganic materials. Based on the molecule design, a new D-π-A structure NLO chromophore molecule [4-nitro-4'-N,N-di aminoazobenzene] 3 with nitro, azobenzene and epoxy is synthesized.

以环氧氯丙烷、苯胺、对硝基偶氮苯胺为原料，设计并合成了一种具有推拉电子结构、含双环氧基的偶氮类有机非线性光学发色团分子4-硝基－4'-N，N-二缩水甘油氨基偶氮苯。

Some other by-products, such as benzoquinone and maleic acid, were unsaturated and contain C＝C double bond which were prone to be attacked by ozone

另外一些中间产物，如马来酸和苯醌等属于不饱和有机物，含有较易被臭氧分子攻击的C＝C双键

The spectral data suggest that intramolecular carbonyl oxygen to tin coordination in 1 is existent and is not allowedin order to accommodate two and three bidentate dithiocarbamate ligands in 3 and 4 respectively.

波谱数据表明化合物1和2存在着分子内羰基氧原子对锡原子的配位，而在化合物3和4中这一配位则被两个或三个双齿二硫代氨基甲酸配体所替代。

Objective: To investigate the effect of diclofenac sodium to the changes of MMS,PGs in aqueous humor in rabbit after Nd:YAG laser posterior capsulotomy.

目的 ：探讨双氯酚酸钠对兔眼Nd ：YAG激光晶体后囊膜切开术后房水内中等分子物质及花生四烯酸代谢产物变化的影响。

Also studied was aza Diels-Alder reaction catalyzed by polyclonal antibody. The bicyclic [2, 2, 2] heptene and the aimed immunogen were synthesized via the key intermolecular asymmetric aza Diels-Alder reaction. Then four polyclonal antibodies were obtained by immunizing rabbit.

在研究多克隆抗体催化氮杂Diels-Alder反应中，通过分子间不对称氮杂Diels—Alder反应为关键反应合成了双环[2，2，2]庚烯类半抗原和目标抗原；用目标抗原免疫动物兔后得到了4株多克隆抗体，经动力学测试表明：多抗Aza-Bsa-3#能催化氮杂Diels—Alder反应的进行。

The results showed that Ni\+\{2+\} bonds with O\+\{2-\} of the SiO\-2 support in bidentate fashion and is terminated with the two methoxyl groups.

结果表明，负载型单核金属甲氧基配合物 Ni(OCH3) 2 / Si O2 中，Ni2 +与载体 Si O2 表面的 O2 -以双齿形式配位；在催化剂表面存在 CO2 的桥式吸附态和甲氧碳酸酯基物种两种吸附态，CH3OH则只有一种分子吸附态。

Double-antibody sandwich method for determination of 2 price or value of more than two macromolecular antigen, but not for the determination of haptens and small molecules unit antigens, because of two points can not form the sandwich.

双抗体夹心法适用于测定二价或二价以上的大分子抗原，但不适用于测定半抗原及小分子单价抗原，因其不能形成两位点夹心。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
