化工专业英语课文翻译如下:

Although the use of chemicals dates back to theancient civilizations,the evolution of what we know as the modern chemical industry started much more recently.

尽管化学品的使用可以追溯到古代文明时代,我们所谓的现代化学工业的发展却是非常近代(才开始的)。

It may be considered to have begun during the Industrial Revolution,about 1800,and developed to provide chemical raw materials industry.

可以认为它起源于工业革命其间,大约在1800年,并发展成为为其它工业部门提供化学原料的产业。

Examples are a lka li for so apmaking,bleaching powder for cotton,and silica and sodium carbonate for glassmaking.

比如制肥皂所用的碱,棉布生产所用的漂白粉,玻璃制造业所用的硅及Na2CO3,我们会注意到所有这些都是无机物。

石蜡一词,来自拉丁语“parum affinis”(极少亲和性的) ,指的是化学惰性的物质,并也适用于从石油和高级烷烃混合物中的得到的蜡。obtanable打错了,应该是obtainable, “能得到的”.slight affinity是“极少亲和性的”的,也即化学惰性的。

请楼主放心采纳,你还在别的地方发了帖,我也已答复。请一并采纳。Electron dot formulas clarify the mechanism of forming a coordinate bond in the neutralization of a Lewis acid. Neutralization of a proton by an ammonia molecule is A电子点方程澄清了在路易斯酸的中和作用中形成配位键的机理。一个质子被氨分子的中和为A The acid — base pair Al3+ and H2O undergoes Lewis neutralization by forming six coordinate bonds.酸碱对Al3+ 和H2O通过形成6个配位键经受路易斯中和作用。 Many displacement reactions illustrate the relative strength of the Lewis acid or base. For example, the cyanide ion is a stronger base than the fluoride ion by virtue of its ability to displace the fluoride ion from the hexafluoroferrate (III) ion: FeF63- + 6CN- ------→ Fe(CN)63- + 6F-很多置换反应表示了路易斯酸或碱的相对强度。例如,氰化物离子就其从六氟高铁酸盐(III)离子中置换氟化物离子来说是一种比氟化物离子更强的碱:FeF63- + 6CN- ------→ Fe(CN)63- + 6F- There are many reactions that fit the Lewis acid-base concept. In contrast to proton loss or gain in the Bronsted-Lowry concept, the Lewis concept emphasizes the electron pair ------a Lewis acid lacks an electron pair in an empty orbital, or has an orbital that can be vacated and a Lewis base has a nonbonding electron pair and can supply this pair to another substance lacking an electron pair.有很多反应符合路易斯酸-碱概念。与质子在Bronsted-Lowry概念中的损耗或增益相反,路易斯概念强调电子对——路易斯酸在一条空的轨道上缺少一个电子对,或者有一条可以是空的轨道,而路易斯碱则有一个非键合的电子对,并能够将此电子对提供给另一种缺少一个电子对的物质。 It is evident that the Lewis concept applies, not only to the chemical behavior correlated by the Bronsted-Lowry concept, but also to many chemical reactions that do not involve proton transfer, and for this reason it is most useful. Its generality precludes the establishment of a scale of acid and base strengths for all Lewis acids and bases, but comparisons can be made between selected substances.显然,路易斯概念不仅适用于由Bronsted-Lowry概念相关的化学行为,而且适用于很多不设计质子传递的化学反应,由于这个理由,它是最有用的。它的通用性妨碍了对所有路易斯酸和碱来说一定范围的酸碱强度的确立,但是在所选择的物质之间可做比较 The terms nucleophilic, and electrophilic are sometimes applied to bases and acids. Lewis acids that accept an electron pair are electrophilic, and the strength of Lewis bases is measured by their tendencies to supply electrons. For example,H2O is a stronger base than Cl- because H2O displaces Cl~ in supplying an electron pair for the proton: HCl+H2O------→H3O+ + Cl-术语“亲核的”和“亲电子的”有时被用于碱和酸。接受一个电子对的路易斯酸是亲电子的,而路易斯碱的强度用它们提供电子的倾向来衡量。例如H2O就是一种比Cl-强的碱, 因为H2O在为质子提供一个电子对能置换ClConsequently , H2O is a stronger nucleophilic agent than Cl-. 因此,H2O是一种比Cl强的亲核剂

注意一楼的回答,这是关键。学英不用中,用中不用英。同样的内容英中各学一次,至少叫做”脱......费二遍事“。浪费时间生命!

没有,像专业一点这种基本不可能会有翻译软件。。。语法不过关也就算了,主要是翻译软件为了尽可能翻译,都会用一些最大众的意思。。所以很多专业词汇都不行,我遇到的最好的基本就是google translate,虽然不保证语法准确,但是有时候一些专精词汇是可以找到的。这种情况不是找人翻译,就是先拿google trans翻译一遍,自己在纠正一遍,後者的话,一般会通篇都改掉,只是会保留一些词汇

In this paper, m-substituted benzaldehydes and home of Phosphonium as raw material by Witting reaction, synthesis of the 7 different substituents p-XC6H4CH = CHC6H4X-p, and their structures were determined by nuclear magnetic resonance, and measured the corresponding UV absorption spectrum. Quantitative changes in the single substituted p-XC6H4CH = CHC6H4X-p of the UV absorption spectra. Combined with the experimental data of other researchers to further explore the changes in the double substituted p-XC6H4CH = CHC6H4X-p of the ultraviolet spectrum law. The results show that the substituent parameters of the excited state of the system adapted to the UV spectra.

In most of the operations encountered in the chemical and petroleum industries,one or more of the processes of momentum,heat,and mass transfer is involved.Thus,in the flow of a fluid adiabatic conditions through abed of granular particles, Momentum transfer takes place between the fluid elements which are moving at different velocities||在大部份的操作方面在化学物质和石油业中遇到了,动力,热和块移动的一个或者更多个程序是 involved.Thus,在流经的流动断热的情况流动在床上粒状粒子,动力移动在正在不同的速度移动的流动的元素之间发生. Here,then,is an example of a process of simultaneous momentum and heat transfer in which the same fundamental mechanism is affecting both processes .fractional distillation and gas absorotion are frequently carried out in a packed column in which In a very turbulent fluid the rates of transfer per unit area of both momentum and mass are high ;and as the pressure rises the rates of transfer of both momentum and mass increase together , It will now be shown not only that the process of momentum ,heat, and mass transfer are physically related ,but also that quantitative relations between them can be developed||在这里,然后,是相同的基本机制正在影响两者的程序的同时动力和热移动的程序的一个例子。微少的蒸馏和瓦斯 absorotion 时常在被包装的专栏被实行在哪一个 在非常狂暴的液体中动力和块的每单位区域移动的比率是高的 ;而且如压力一起上升动力和大众的增加的移动的比率 ,它现在将会被显示不但动力,热和块的程序转移身体上地被讲 , 而且那数量的关系在他们之间能被发展||微少的蒸馏和瓦斯 absorotion 时常在被包装的专栏被实行在哪一个在非常狂暴的液体中动力和块的每单位区域移动的比率是高的 ;而且如压力一起上升动力和大众的增加移动的比率,它现在将会被显示不但动力,热和块的程序转移身体上地被讲 , 而且那数量的关系在他们之间能被发展. Another form of interaction between the transfer processes is responsible for the phenomenon of thermal diffusion in which a component in a mixture moves under the action of a temperature gradient .although these are important applications of thermal diffusion ,the magnitude of the effect is usually small relative to that arising from concentration gradients||在移动程序之间的另外形式的交互作用负责热散布的现象在哪一个一个混合的一个成份在温度倾斜度的行动之下移动。虽然这些是热散布的重要申请 ,效果的大小通常对那是小的亲戚从集中倾斜度出现||虽然这些是热散布的重要申请 ,效果的大小通常对那是小的亲戚从集中倾斜度出现. When a fluid is flowing under streamline condition over a surface ,a forward component of velocity is superimposed on the random distribution of velocities of the molecules, Thus if two adjacent layers of fluid are moving at different velocities ,there will be a tendency for the faster moving layer to be retarded and the slower moving layer to be accelerated by virtue of the continuous passage of molecules in each direction||当液体正在在一个表面上的流线情况之下流动的时候,一个速度的向前成份在分子的速度的任意分配上被重叠,如此如果二毗连液体的层正在不同的速度移动 ,比较快速的感人层将会有趋向是智能迟滞的和比较慢的感人层由于每个方向的分子的连续通道被加速 . Similarly , the molecular motion will tend to reduce any temperature gradient or any concentration gradient if fluid consists of a mixture of two or more components||如果液体有一个二或较多成份的混合,同样地,分子的运动将会容易减少任何的温度倾斜度或者任何的集中倾斜度. If the motion of the fluid is turbulent , the transfer of fluid by eddy motion is superimposed on the molecular transfer process .in this case ,the rate of transfer to the surface will be a function of the degree of turbulence .when the fluid id highly turbulent, the rate of transfer by molecular motion will be negligible compared with that by eddy motion .for small degrees of turbulence the two may be of the same order||如果液体的运动是狂暴的 , 逆流运动的液体的移动在分子的移动程序上被重叠。在这情况,到表面的移动的比率将会是喧嚣的程度的一个功能。||在这情况,到表面的移动比率将会是喧嚣的程度一个功能。当流动的遗传素质高度地狂暴的, 分子运动的移动的比率藉着逆流运动将会是可以忽略的与那相较。对于喧嚣的小程度那二可能是有相同的次序的 . In addition to momentum ,both heat and mass can be transferred either by molecular diffusion alone or by molecular diffusion combined with eddy diffusion .because the effects of eddy diffusion are generally far greater than those of the molecular diffusion ,is occurring. Thus the main resistance to the flow of heat or mass to a surface lies within the laminar sub-layer . Thus the heat and mass transfer coefficients are much higher at high Reynolds ||除了动力之外,热和块能被转移或被分子散布孤独的或被被和逆流散布结合的分子散布。因为逆流散布的效果是通常远比棒的那分子散布的那些 ,正在发生||因为逆流散布的效果是通常远比棒的那分子散布的那些 ,正在发生. Thus the main resistance to the flow of heat or mass to a surface lies within the laminar sub-layer||如此对 laminar 子层里面的一则表面的谎言对热或块的流程主要的抗拒 .
