It was shown that, the flow pattern in the EMPT was more complex than that in traditional one, that is, in the column chamber, the short circuit flow from the outlet nozzle of the ladle was depressed by the rotating molten steel, and horizontal recurrent flow appeared in rectangular chamber, which prolonged the average staying time of the molten steel, then reduced the volume fraction of inactive area in EMPT.

结果显示，电磁净化中间包的流场比传统中间包的流场复杂：在圆形腔中，旋转运动抑制了大包水口至矩形腔的短路流，而在矩形腔中形成水平环流，从而延长钢液在中间包的平均停留时间，死区减小，电磁净化中间包的上述流场结构及传输行为对钢液中的非金属夹杂物去除非常有利。

Mr Aso, a Catholic, is the grandson of Shigeru Yoshida, a former prime minister (seated above; the young Mr Aso is standing in the centre) and as blue-blooded as they come.

麻生先生，是一名天主教徒，他是前首相吉田茂的外孙（上图照片中端坐者为吉田茂；站在中间的孩子就是幼时的麻生），与他的爷爷一样都是含着银勺子出生的贵胄子弟。

The US, the Hmong's former patron and military ally, is stuck in the middle of the controversy and critics say Washington is now more concerned with counterbalancing China's growing regional influence than taking a stand for the marginalized ethnic minority group.

美国，苗族的前靠山和军事盟友，是卡在中间的争议和批评人士说，华盛顿现在更关心的是制衡中国不断增长的地区影响力不是采取的立场被边缘化的少数民族群体。

Viruses do 'escape' from laboratories, even high security facilities. The H1N1 influenza lineage that circulated in the human population for four decades after the 1918 Spanish influenza epidemic, disappeared during the 1957 Asian influenza pandemic, was absent for two decades, but then reappeared in 1977. Gene sequences of the 1977 isolate and others collected in the 1950s were almost identical, indicating that the virus had not replicated and evolved in the interim, and had probably been held in a laboratory freezer between 1950 and 1977 and 'escaped' during passaging.

病毒确实从实验室中'逃跑'，即使有高度保护设施。H1N1家族流感病毒，在人类传播了40年自1918年西班牙流感疫情之后，在1957年亚洲流感大流行后失踪，消失了20年，但随后在1977年重新出现。1977年分离基因序列和在20世纪50年代收集的基因序列几乎相同，这表明病毒并没有复制和演变在中间期，并可能在1950年至1977年保存在实验室冷冻器，又在中间期内&逃脱&出来。

If you bent or folded rock, the inside of the curve was in a state of compression, the outside of the curve was under great tension, and somewhere in the middle was the surface of no strain.

&假如你把一块岩石弯曲，曲面的内侧会是一种紧缩的状态，外侧则处于巨大的张力，而在中间的某处则是光滑无痕的平面。&

Briefly described measures taken in purifying the liquid steel to improve steel quality such as expansion of tundish capacity,installation of stop plate,separating wall,overflow dam and ceramic filter at the tundish and adoption of high basicity flux as well as reheating of liquid steel in the tundish.

简述了通过中间包扩容；在中间包内增设挡扳、隔墙/溢流堰、陶瓷过滤器，采用高碱度中间包保护渣以及中间包钢液加热等措施，净化钢水，提高钢的质量。

The shell of this room to me is perfect; it's the contents that need improving, as all of this excitement surrounds a bit of a disappointing middle.

这个空间设计的框架对我来说是非常完美的，但是它的内容，我认为还是需要做一些改进的，就像一个令人激动的周围但是在中间的设计确令人有些失望。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
