查询词典 conic polar

An amphiphilic compound has a polar head which dissolves in water and a water insoluble organic tail.

双亲分子有一个能溶解在水中的极性基团和一个疏水尾。

As a result, a weak indirect cell is formed in high latitudes. By the 36th time step, the model atmosphere accomplishes the transition form one-cell circulation to two-cell circulation. There is a momentum source in the upper subtropical region. During the transition, the"polar westerlies jet"gets weakened and vanishes at the end, while the subtropical westerlies jet gets strengthened. At this two-cell stage, the generation and dissipation of westerly angular momentum do not balance each other, and the atmosphere is still at an unstable state with great surplus of angular momentum generation.

随着模式的运行，直接环流加强，地表东风带制造西风角动量加大，上支气流的加强，同样在科氏力的作用下，在副热带地区形成副热带西风急流，同时所谓的&极地西风激流&向赤道靠拢、减弱，最后消失，这时在整个半球形成了靠赤道的直接环流和靠极地一侧的间接环流，两圈环流形成的过程仅仅需要9个小时左右。

In addition, as it be the most sedentary period of sunspot activity in the past 11 years this year, this has influenced earth's magnetic field and atmospheric circulation to make the weather colder in Polar Regions.

加上今年碰上太阳黑子活动为11年来最低进而影响地球磁场及大气环流，才会使得北极圈天气变冷。

The results show that methyl group strengthens the electrostatic attractions, but reduces the H-bonds effect, while benzyl group can make both electrostatic and H-bond effects strong. The theoretical results are identical with the results of the collectors flotation tests. Collecting ability of the quaternary amine salts is better than that of dodecylamine and dodecyl bimethyl amine. The quaternary amine salt containing benzyl group performs best, and it is little affected by pH value. Substitution of N-containing polar group in amine collectors can impact the aluminosulicate minerals flotation.

研究结果表明：甲基的取代可增强阳离子的静电作用能力，同时，削弱它与矿物表面之间的氢键作用；苄基的取代不仅增强药剂的静电效应，而且增加氢键的结合能力；理论分析结果与浮选试验结果一致，季铵盐的浮选能力较伯胺与叔胺的强，连有苄基的季铵盐对铝硅酸盐矿物的捕收能力最强，且受pH值影响小。

"We are in the midst of a phase of dramatic change in the Arctic," said Ursula Schauer, the chief scientist at the Alfred Wegener Institute, who was on board the Polar Stern expedition.

&我们正处于一个阶段的戏剧性变化在北极，说：&厄秀拉schauer ，首席科学家在阿尔弗雷德wegener学院，他们是在船上极地斯特恩远征。

An international team of scientists on board the Polar Stern, a research ship operated by the Alfred Wegener Institute in Germany, also felt the effects of an exceptionally warm Arctic summer.

一个国际科学家团队对董事会极地严峻，这是一个研究船是由阿尔弗雷德wegener研究所在德国，也感受到效果异常温暖，北极的夏季。

Friedmann, city space-filling developing models can be divided into four phases that are low-level balance phase, polar nucleus development phase, concentration-proliferation phase and high-level network development phase.

按J·弗里德曼的城市空间组合发展模式可分为：低水平均衡阶段、极核发展阶段、集聚—扩散阶段、高水平——网络化发展阶段。

Little Bear longs to be as big and as fast as his mother. In the cold arctic snow, Mother Bear shows the little polar bear cub what it's like to be grown up.

简 介：在这个故事中，北极熊妈妈告诉她的熊宝宝长大后会变成怎样，能做什麼事，是一本充满了母子？

Vashti's teacher leaned over blank paper."Ah! A polar bear in a snow storm," she said.

沃诗提的老师探身看着空白的画纸，惊叹道：&哇，是一只冰天雪地里的白色北极熊&。

He paid $5,000 for this cupcake.

他我这个纸杯蛋糕花了5000美元。

I mean, if you want to, that is

我的意思是，如果你们想吃的话。
