查询词典 abstraction operator

Through analysis on the present technologies, this study discovered that low-temperature condensation is a relatively matured method with high cost and highly-consumed energy; the other methods like adsorption, absorption and membrane osmose process are differently characterized by many features hut have not been applied in industrial use for many reasons, Along with many new materials and techniques, helium abstraction technologies from natural gas have been innovated like the adsorption arid membrane osmose process have developed fast and co-production and combined technologies have a good application prospect, which provide new thoughts for the development of helium abstraction technologies from natural gas.

通过对目前提氦技术的分析介绍，低温冷凝法较为成熟，但能耗、成本较高；吸附法、吸收法和膜渗透法等其他提氦技术各其特点，但目前限于适用条件尚不能规模化工业应用，随着新材料、新技术的发展，天然气提氦技术不断改进创新，吸附法、膜渗透法等提氦工艺发展迅速，联产法、联合法工艺有着良好的应用前景，这些都为促进天然气提氦技术的发展提供了新的思路。

In Chapter 5,the pyrolysis of substituted six-membered ring model compound 4-methyl pyridine has been investigated.Instead of detail theoretical analysis of the reaction mechanism,the general results have been proposed from the products distribution and the combination of the pyrolysis investigation of its analogous pyridine.The major products are H_2,C_2H_2,C_4H_2,C_3H_3N and HCN,here HCN is not a primary initial product at low extent of decomposition.The mole fraction profiles of products have been obtained from the near threshold ionization.The pyrolysis of 4-methyl pyridine is initiated from the methyl abstraction and hydrogen abstraction procedures which are associated with the understanding of the soot formation and the NOX precursor correspondingly.

主要产物为H_2，C_2H_2，C_4H_2，C_3H_3N和HCN，其中HCN为非低温时的热解产物；通过近阈值电离并导出物种随温度变化的摩尔分数曲线，更详细地定量地描述了产物随温度的变化。4-甲基吡啶热解主要从母体脱甲基和脱氢两个初始反应出发，一种趋势是形成大质量数的苯并或杂环的多环化合物，有助于了解炭黑形成过程中的复杂化学过程；另一趋势是开环生成小的碳氢和腈类物质，实验得出的含氮物质的种类及随温度变化有助于了解NO_x的前驱物质的形成及其变化规律。

Osapi 2.0 Operating System Abstraction Layer "system abstraction layer" allows you to achieve an RTO S, CPU and the operating characteristics of the physical products fully transparent software.

详细说明： osapi 2.0 操作系统抽象层"系统抽象层"使得你可以实现一种对于RTOS、CPU和所运行产品物理特性完全透明的软件。

From these sweet, bitter, sour objects, sweetness, bitterness, sourness, are abstracted. Once abstracted they can be reapplied;…… For example an emotional experience is associated with the breast, in which the infant feels that there is an object existing independently of itself on which it can depend for satisfaction of its feelings of hunger; assuming a capacity for abstraction, the infant can feel that from the total experience he can detach an element which is a belief that an object exists that can satisfy his needs. The concrete statement might be: a breast exists that can be depended on to satisfy his hunger for food; abstraction from this might be: there is a something that can and does give him what he wants when he wants it. Bion,

从这些甜的、苦的、酸的客体中，甜、苦、酸被抽象出来，它们便可再度被应用；……例如：婴儿有一个与乳房相关的情绪体验，在其中他觉得有一个客体独立于他自己而存在，且可以依赖这个客体来让饥饿感得到满足；如果婴儿有抽象的能力，他就能够觉得从这整体体验中，可以分离出一个元素，此元素是一个信念，亦即，相信一个可以满足其需求的客体，具象的叙述可能是：存在一个乳房，他可以依赖此乳房来满足对事物的渴求；从此抽象出来的则可能是：存在某种事物，当他需要的时候能够且的确会给他那些他想要的。

This paper points out that although the abstraction of Rawls' method of contract theory is embodied in the three stages of the pre-establishment of the original position, construction of the veil of ignorance, and the rational choice, the real abstraction of it should be grasped through the broody frame of reflective equilibrium.

本文认为，罗尔斯契约论方法较之于传统契约论的抽象性虽然具体体现在原初状态的预设、无知之幕的构建以及合理选择这三个环节之中，但对于其更为深刻的把握则在于对&反思的平衡&这一总体思维架构的理解。

Furthermore, single-point energy calculations were refined at the QCISD level of theory with the same basis set (6-311++G**). As a result, the singlet reaction of silylene with isothiocyanic acid contain S-atom abstraction channel, N—H inserted channel, and NH abstraction channel, respectively.

又用QCISD/6-311＋＋G**//B3LYP/6-311＋＋G**方法计算了各个驻点的单点能，计算结果表明单重态的硅烯与异硫氰酸的反应有抽提硫、插入、抽提亚氨基的路径。

This thesis did the next research about the appliance of ionic exchange resin in the aspects of the abstraction in the VC abstraction shop manufacture process .1, The text filtrated ion exchange resin .

本论文对离子交换树脂在VC生产中的提取工序中的应用进行了以下几方面的研究：1、本文对离子交换树脂的进行了筛选。

Dave Thomas: Yes, once you adopt a discipline of separating the abstraction and the data that abstraction is working on, your code starts being structured in a far tidier way. Your code tends to be decoupled and orthogonal.

戴夫·托马斯：是的，一旦你采用了这种方法，将数据和作用于其上的抽象分离，你的代码就会开始变得更加有条理、结构更好，你的代码的耦合程度会更低，更具正交性。

In the opinion of Arthur Danto, the innovation of modernism artThe article regards abstraction of modernism art as the first part: the emergence of impressionism, post-impressionism, the development of modernism—it is a course of gradual abstraction; Art after Duchamp is as the second part: Duchamp and Dadaism, Surrealism, the device and Neo-Dadaism, Pope"s art, from Minimist art to idea art, New-figuration—it is a diversion of abstract art, has realized its oneself Along with Greenburgh"s impetus, and already obtained what it wanted at the beginning ------ so it has ended.

依阿瑟·丹托之见，现代主义艺术的创新随着格林伯格的推动已经实现了它自身，已经取得了它在出发伊始就想要取得的东西——所以它终结了。那么在这个&艺术已经终结&后的&后历史&、&后美学&或&后现代主义&时期，艺术需要以新的方式重新解读。

Summary: Regard guava as raw materials, adopt the organic solvent to extract the law, pass the single factor experiment and orthogonal experiment, to influence many phenol draw abstraction pharmaceutical kind of quantity, draw pharmaceutical volume mark, draw time, draw temperature factor go on the discussion compared with material liquid,etc., the ones that confirm much phenol of guava draw the craft parameter bestly: Volume mark 70% ethanol according to material 1:10 volume ratio of liquid, 70 ℃lay reflux draw 40min in temperature, many abstraction amount of phenol can reach 62.35mg/g be thing.

问题补充：不好意思，我修改了一下摘要，正文应该是：以番石榴为原料，采用有机溶剂萃取法，通过单因素实验和正交实验，对影响多酚提取量的提取剂种类、提取剂体积分数、提取时间、提取温度和料液比等因素进行探讨，确定番石榴多酚的最佳提取工艺参数为：体积分数为70%的乙醇按1∶10的料液比，在温度70℃下回流提取40min，多酚的提取量可达到62.35mg/g干物。
