查询词典 first-order reaction

We look at that 6-foot-10 body, at his pterodactyl wingspan, his vast portfolio of skills, and think:"Perennial All-Star." Then we find that in nine years Odom has never been to an All-Star game but a journeyman like Wally Szczerbiak has and our first reaction is that this is utterly maddening and pretty much a waste of great talent.

他那6尺10村的身板，超长的臂展和丰富的比赛技能，总让人认为他应该是常年参加全明星的球员，但是在奥多姆9年的职业生涯中，我们从没看到过他参加全明星赛，而像苏泽比亚克这样的二流球员都曾经参加过全明星赛，我们的第一反应是这完全是发疯了，也是对人才的巨大浪费。

Two representative compounds have been determined by X-ray crystallography. The best ratio of reactants, the adequate reaction temperature and solvent have been found by contrast experiments.4. The better photoreaction conditions and irridation times have been confirmed through the different photoreaction results. It is the first time that fifty quinazoline derivatives with biological activity and four photooxidation products with urea functional groups have been obtained by photochemistry method. Two representative compounds, quinazoline derivatives and photooxidation products, have been determined by X-ray crystallography, respectively.

通过实验对比我们找到了较佳的反应物的投料比、反应温度和反应所用的溶剂。4、根据不同条件下的光反应结果，确定了硫脲衍生物的相对较好的光反应条件和光照时间，首次利用光化学手段成功得到50个具有生物活性的喹唑啉衍生物和4个具有脲基官能团的光氧化的产物，测定了两个具有代表性的喹唑啉和光氧化的产物的晶体结构。

This dissertation involves the study of the growth dynamics of colloidal particles under unequilibrium and irreversibility condition. Firstly, it is of interest to investigate whether the ideal diffusion or reaction-limited aggregation universal behavior can be observed for the initially polydisperse practical system of basic yttrium carbonate as well. The fractal structure of basic yttrium carbonate aggregate cluster was observed using transmission eletron microscopy. The aggregation kinetics of basic yttrium carbonate colloids was studed using dynamic 1ight-scattering techniques. At 1.00mol/l NaCl solution the fast diffusion-limited aggregation behavior was observed with an increase in the aggregate size over time described by a power law. The aggregates are characterized by a fractal dimension D=1.82. The disordered and ramified cluster is consisted of primary colloidal particles and tenuous and more open. These are in good agreement with those observed for other colloidal system such as colloidal gold (1.86), silica (1.85) and polystyrene latex (1.82) in diffusion-limited aggregation from the static and dynamic light scattering by Lin. Therefore ideal diffusion-limited aggregation behavior can be observed in practical polydisperse system as well. Smoluchwski and fractal theories were used to obtain the aggregation rate constant for initially polydisperse system for the first time.

本论文研究胶粒的非平衡不可逆聚集动态学，分为两个部分，第一部分是通过实验研究一个新的初始多分散的碱式碳酸钇胶粒实际体系中，聚集标度性质的普适性，即使用透射电子显微技术观测聚集粒子簇的分形结构，使用动态激光光散射研究碱式碳酸钇胶粒的聚集动力学，胶粒带电而产生静电排斥作用使得碱式碳酸钇胶粒处于稳定状态，当加入电解质NaCl溶液时，碱式碳酸钇胶粒间的Debye-Hückel屏蔽距离缩短，从而降低静电排斥能垒，引起胶粒发生不可逆聚集，加入电解质NaCl的浓度为1.00mol/l时，碱式碳酸钇胶粒进行快速聚集，经历扩散控制聚集机理，形成结构疏松、更为开放的分形聚集粒子簇，其分形维数为1.82，碱式碳酸钇胶粒聚集增长动力学遵循幂函数增长规律，与Lin等使用静态激光光散射和动态激光光散射测量硅胶(1.85)、金胶(1.86)和聚苯乙烯胶乳(1.82)在扩散控制聚集状态形成聚集粒子簇的分形维数值以及粒子簇聚集增长的动力学规律相一致，表明胶粒聚集标度性质的普适性质在初始多分散的实际体系中也是存在的，首次由动态激光光散射的实验数据得到初始多分散胶粒分形粒子簇的聚集速率常数，并且其值与Smoluchowski聚集速率理论预期相符。

After eight years to see the re-release dragons, his first reaction was:"wow, pack Need to get out, he has become quite the type to see if he feels like he has grown bigger."

八年后再度见到释小龙，他第一个反应是："哇，型男，他变得满有型的，看他长大感觉自己也大了。"

凯凯第一次打预防针是在他2个月的时候，他的反应很有趣。

Today, I kissed the girl I love for the first time. Her reaction ?

今天，我第一次和我爱的女孩KISS，她什么反应？

My first reaction is, I don't know if I want to or not.

我的第一反应是，我不知道我想要什么。

My first reaction is to say get out of there.

我的第一反应是说离开这里。

Ben-Gurion's first reaction demonstrated his ability to bridge the gap between the utopian dimension of his leadership and his realpolitik approach.

本-古里安对报告摘要的第一个反应表明了他弥合领导人的空想和权力政治之间的能力。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
