研究结果表明：合成的化合物在非极性溶剂中有双重荧光的稳态发射行为；双重荧光中的长波长发射经时间分辨光谱研究为双指数发射衰减；其中的长寿命衰减是由于该类化合物在非极性溶剂中激发后经过分子内电荷转移形成了激基复合物所致，而产生该激基复合物的直接原因是由于在非极性溶剂中的&harpooning effect&所致，短寿命则来自于该类化合物激发后在溶液中发生了分子内电荷转移的直接衰减。

To estimate the bioconcentration factor of benzene derivatives in fish by gas chromatography retention time, this paper measured the BCF of chlorobenzene, o-chloro-toluene, p-dichlorobenzene, m-dichlorobenzene, 1,2-dichlorobenzene, nitrobenzene, p-chloro-aniline, p-chloro-nitrobenzene, and 4-chlorodiphenyl in grass crap, and the t_R of test derivatives on the stationary phases of six kinds polarity.

为了用气相色谱保留时间估算取代苯类化合物在鱼体内的生物富集系数，测定了草鱼对氯苯、邻氯甲苯、对二氯苯、间二氯苯、邻二氯苯、硝基苯、对氯苯胺、对硝基氯苯、4-氯联苯9种取代苯类化合物的BCF和不同取代苯化合物在6种不同极性固定相上的tR，建立了tR与BCF的一元回归方程及tR一阶分子连接性指数(1XV)与BCF的二元回归估算方程。

At last, in the absence of molecular oxygen, dehydrogenation of FMMH〓 in Photobacterium phosphoreum might be interrupted by the reaction between the Cyanide Alcohol Carbanion and Flavin monoclevtide .

以相加作用的非极性麻醉型有机化合物、极性麻醉型有机化合物和反应性化合物为研究对象，分析了各种相加作用的不同本质。

Choose sensible carbohydrate-rich foods. Carbs don't have to be gooey and chocolatey every time, Wurtman says. She suggests low-fat crackers, for instance, or pretzels. It keeps the fat low but gives you the carbs you want.

对富含碳水化合物的食品要有所选择，碳水化合物并不总是意味着蜜糖和巧克力食品，Wurtman说，她建议选择低脂饼干如椒盐饼干，它含较低的脂肪并且能够满足你对碳水化合物的需求。

Eating carbohydrates seems to help carb cravers feel better in about 20 minutes, according to Wurtman's research. When you eat carbs, your body makes more serotonin, the feel-good hormone that is boosted when you are on an antidepressant.

根据Wurtman的研究，碳水化合物看起来好像能够帮助碳水化合物渴望这在20分钟内感觉情绪好转，当你吃碳水化合物食品时，你的身体会产生更多的复合胺，当你服用抗抑郁药物时同样身体产生更多的这种愉悦感的激素。

The photosynthetic model compounds include dyads, compounds more than two segments and non-covalently linked supramolecular systems.

光合作用模型化合物包括二元化合物、多元化合物和非共价键相连的超分子体系，超分子体系的光化学和光物理是近几年该领域的研究热点。

It is not known whether flavonoids can be absorbed in amounts sufficient to exert an antiviral effect in humans, and therefore their possible role in the treatment of childhood exanthems remains unknown.

约黄酮类化合物抗病毒行动已观察到的试管实验。41 42 43 44 45 槲皮素，黄酮类化合物之一的，所表现出特别强烈的试管抗病毒特性； 46 47 48但是，一项研究没有找到槲皮素将有利于小鼠的病毒感染。49这不知是否黄酮类化合物可吸收的数额不足以在人体发挥抗病毒效果，因此，他们在治疗儿童exanthems可能发挥的作用仍然不得而知。

As yet there is lack of information on the effects of elevated CO_2concentration on carbohydrate contents in stem, branch and root of plant, and oncarbohydrate allocation in organs of plant although there have been many reports onthe responses of carbohydrate contents to elevated CO_2 concentration in plant foliages.

迄今为止，有关CO_2浓度升高对植物叶片中的碳水化合物含量的研究较多，而对其它器官中碳水化合物含量以及碳水化合物在植物体内的分配响应研究较少。

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。
