查询词典 molecules

The proper in-situ polymerization systems of acidic and basic compounds using amino acid derivatives and cinchona alkaloids as template molecules respectively were adopted for preparation of molecularly imprinted monolithic columns by systematically investigating the effect of polymerization conditions on pore structure and selectivity of resulting polymers. The enantiomers of amino acid derivatives and the diastereomers of cinchona alkaloids were successfully resolved on these columns.

Many of the molecules and substances that circulate in body overlap between immune function and sleep, he said.

许多这些分子和物质在身体内循环在免疫力和睡眠之间重叠，他说。

MIP and NIP have very good selective adsorption abilities to both 1 -hydroxy -2 - naphthoic acid and citrinin molecules.

结果表明MIP和NIP对1-羟基-2-萘甲酸和桔青霉素分子都有着很好的吸附选择性。

"Though classical mechanics fails on the scale of atoms and molecules, it remains the framework for much of modern science and technology."

虽然经典力学不能解释原子和分子尺度的情况，但它还是多数现代科学和技术的基本框架

Hydrates are crystalline, non-stoichiometric, clathrate compounds, and are formed from certain guest molecules when contracted with water at favorable temperature and pressure conditions.

水合物是一种非化学计量的笼形结晶化合物，由客体分子物质和水在一定温度和压力条件下形成的结晶状物体。

令人不能预期的是两个closed shell的分子，其速率常数可能像自由基反应一样快。

For example, DNA is always depicted as information but it is really a clump of molecules.

比如，DNA被描述成信息，事实上他只是一凝块分子。

Ultrasonic is a kind of technology which could be used to break up clustered pigment molecules.

超声波是一种技术，可以用来打破群集色素分子。

The effects of excess air coefficient and cylinder pressure on these spectra are also studied. The experimental resultS show that the three different combustion phases in a gasoline engine have different combustion characteristic spectra: a large number of atoms, molecules, ions and radicals which are in their excited states are existing during the ignition process, with the development of the combustion, the spectra intensities of CH, C2 radicals increase rapidly.

实验结果表明，汽油机三个不同的燃烧阶段具有不同的燃烧光谱特征：着火过程中，存在着大量的处于激发态的分子、原子、离子、自由基等活化中心的束缚态光谱，随着燃烧发展，CH、C2自由基的光谱强度明显加强；当减小过量空气系数时，光谱强度变弱并且着火延迟期增长；自由基特征光谱的光强变化曲线可以反映它们在燃烧过程中的浓度变化。

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