临界点

At pressures and temperatures greater than the critical point, carbon dioxide exists only as a supercritical fluid.

在压力和温度大于其临界点时，二氧化碳只可能以超临界流体形式存在。

This is typically done by exchanging the ethanol for liquid acetone, allowing a better miscibility gradient, and then onto liquid carbon dioxide and then bringing the carbon dioxide above its critical point.

这是典型的交流所做的乙醇液体丙酮，允许一个更好的相容性梯度，然后到液体二氧化碳，然后将其二氧化碳的临界点以上。

He looks ahead to find out what needs to be done to save Planet Earth from the worst impact of global warming and discovers what could happen to the planet once a 'tipping point' of carbon emissions is reached.

他从未来的角度分析了全球气候变暖给人类带来恶劣影响后，人们应该采取什么样的应对措施以拯救地球，并预测全球二氧化碳排量一旦突破&临界点&的时候，将会给我们带来什么样的后果。

The critical point of carbon dioxide is 87.9 oF (31.1 oC) and 1070.6 psig (73.8 bar).

二氧化碳的临界点为87.9℉（即31.1℃），1070.6表压(即73.8帕)。

This method selects two parameters, energy and variance, as the characteristic parameter of trolley track, and successfully in extracts the feature frequency belt of trolley track vibration. Furthermore, this technology is applied to practical engineering programs and has good veracity and reliability.2. According to the research of this thesis on the trolley tracks\' present data, the status classification of trolley track with normal distribution is presented. This method divides trolley tracks\' situations into five parts and perfects the classifying method of trolley tracks\' mechanical situation.

具体工作如下；1、将小波包分析方法运用到岸桥小车轨道振动信号的分析中，选取能(来源：A65BC0f论c0文网www.abclunwen.com)量与方差作为轨道的振动特征参数，有效提取出铰点部位与非铰点部位的振动特征频段。2、将正态分布原理引入到岸桥小车轨道铰点机械性能状态的划分之中，并用最大熵概率分布加以验证，准确地反映了实际情况，并定义了正态分布诊断准则的状态分级评价的原则和临界点，方便和简化了状态判断的决策过程。

In Chapter 3, we use the sufficient and necessry conditions of minimal point being critical point on closed convex set and construct closed convex sets with some character as more as possible, to discuss the existence of solusion of nonlinear Hammerstein integral equations on different closed convex sets. We get the results of multiple solutions.

在第三章中，我们没有借助于条件，而是利用闭凸集上的极小值点是临界点的充要条件，构造出尽可能多的具有某些特性的闭凸集，在不同的闭凸集上讨论非线性Hammerstein型积分方程的非平凡解的存在性，从而得到多解性的结果。

For men, the danger point seems to be 40 inches or more.

对男子来说，腰围的危险临界点可能是40英寸以上。

There is so far little evidence that either underlying inflation or the public's long-term inflation expectations have reached a danger point.

目前为止还没有迹象表明，核心通货膨胀或是公众的长期通胀预期已经到达了危险的临界点。

For Moody's, the key metric is interest payments as a percentage of revenue, and the danger point is 10%, a level at which it believes debt becomes a serious constraint on government spending policies.

穆迪认为，关键衡量指标是利息支出占总收入的比例，危险临界点是10%；穆迪认为，如果达到这一水平，债务将会严重制约政府的支出政策。

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。
