查询词典 liquefied petroleum gas

ESI-MS results showed that α-CD could form 3: 1 specific complex with cinchonine in solution and they formed"sandwich"structure type 〓 inclusion complex when β-and γ-CD were blended simultaneously with cinchonine. Semi-empirical AM1 calculations indicated that the H bonds formed between CD and cinchonine played an important role to stabilize the complex in gas phase.

电喷雾质谱研究发现α-CD与辛可宁在溶液中可以形成特异性的3：1型复合物，当β，γ-CD与辛可宁同时混合时它们可以形成"三明治"型〓包合复合物，半经验AM1方法计算显示氢键的形成对这些复合物的稳定起到重要的作用。

Cinder cone volcanoes are formed when magmas with high gas contents and high viscosity are blown high into the air during an eruption.

火山渣锥火山是，当爆发时，高气体含量和高粘度的熔岩被喷发到空气中而形成的。

In order to explore the relationship between the Artemisia frigida Wild. and the intake mass, this reaserch took sheep as reaserch object, using mixture of pasture containing A. frigida in different scales to feed sheep, to analyse the intake mass of the sheep, intake behavior and diet selection strategy, combined with Thermal-desorption Cold Trap/Gas Chromatography/Mass Spectrum to analyse the VOCs from the overground part of A. frigida in July and to identify the compoments; and its major components cineole,α-terpinol ,α-pinene andβ-pinene were added to the sheep feed, to analyse the effects of different monomers of VOCs from A.

为了探讨冷蒿与家畜采食量的关系，本实验以绵羊为研究对象，用含有不同比例冷蒿的混合牧草饲喂绵羊，分析了绵羊的采食量、采食行为及食性选择策略，结合热脱附―气相色谱―质谱联用技术对冷蒿地上部分7月份释放气体进行了组分分析和鉴定；并将其主要成分桉树脑、α-萜品醇、α-蒎烯和β-蒎烯添加到绵羊的饲料里，进一步分析了不同冷蒿挥发物单体对绵羊采食量、采食行为及食性选择策略的影响。

Besides all kinds of brutality in the concentration camps, the gas room and cinerator, there is also a red-dressed Goethe sitting nearby on the grass below the castle. The soldier sitting beside him is the painter, who is questioning Goethe and the audience:"What's wrong with the great German people?"

除集中营的各种暴行，煤气室和焚尸炉外，还有穿着红衣的歌德坐在画面近处城堡下的草地上，边上坐着的士兵是我的自画像，在向观众也在向歌德发出诘问，伟大的德国人民怎么啦？

Much of the gas in the disk of the Circinus spiral is concentrated in two specific rings -- a larger one of diameter 1,300 light-years, which has already been observed by ground-based telescopes, and a previously unseen ring of diameter 260 light-years.

在圆规座的漩涡星系中的大部分气体都与两个具体的"环"有密切的联系。那个较大的，直径大约有1，300光年，它已经被地基望远镜观测到了。而先前，我们没有观测到的那个小"环"，直径大约有260光年。

Fortunately, the resource of coal and natural gas is rich in the world, how to make use of these two resources efficiently and cleanly becomes the significant problem that the circle of industry and science technology fully concern about in the world.

由于世界煤和天然气资源十分丰富，如何更经济有效、并洁净地利用这两种资源，是全球工业和科技界十分关心的重要问题。

In this paper , the study of gas-solid flow past a circular cylinder with PIV and The Streamline System is initiated.

在国家自然科学基金的资助下，本文率先运用PIV技术和热线风速仪等手段对水平两相方柱绕流拟序结构进行了相关的研究。

Rotating disks are the basic mechanical element of steam and gas turbines, grinding wheels, circular saws, and computer disk memories.

旋转圆盘是工业中应用广泛的一种基本机械元件，它广泛的应用于旋转机械，诸如涡轮机、圆锯、计算机硬盘等，上述系统中这些盘类结构严重的横向振动将使机器工作时的精度降低﹑动态性能下降以及造成被加工材料的浪费，严重时甚至使圆盘元件损坏。

Rotating disks are the basic mechanical element of steam and gas turbines, grinding wheels, circular saws, and computer disk memories. Large amplitude transverse vibration of rotating disks can cause failure of turbine wheels due to wheel-case contact, cutting inaccuracy for grinding wheels and circular saws, the waste in material and head-tracking errors in computer disk memories.

旋转圆盘是工业中应用广泛的一种基本机械元件，它广泛的应用于旋转机械，诸如涡轮机、圆锯、计算机硬盘等，上述系统中这些盘类结构严重的横向振动将使机器工作时的精度降低、动态性能下降以及造成被加工材料的浪费，严重时甚至使圆盘元件损坏。

This paper establishes a mathematical model of the gas flow field inside separating column of the circumfluent circulation cyclone separator based on the N-S equation under column coordinate,gives the resolution of the cyclone flow field in separating column with weighted residual method,and compares computation values with trial values as well.

由柱坐标系下的Navier-Stokes方程出发，建立了环流循环除尘系统分离柱内流速场新的数学模型，利用具有成熟使用经验的加权残值法对流场进行求解，并与实验结果进行了比较。

Finally, the Knight strung a line between two of the monoliths and tied the horses up there.

最后，骑士们在两颗巨石之间拉了一条绳子，将他们的座骑绑在上面。
