水柱

This has to do with the way a deep column of water boils.

这是因为一个深层水柱的沸点造成的。

At the same instant, however, there was a terrific clap of thunder, a fragment of earth in the middle of the court-yard sprang Like a cannon-ball into the air, and over the castle, and directly after it a jet of water rose as high as a man on horseback, and the water was as pure as crystal, and the sunbeams began to dance on it.

就在这一刹那，凌空一声霹雷响，一大块泥土好像炮弹一样从院子中央直射天空，落到了王宫外面，随后便是一股水柱直喷出来，像水晶一样清澈透明，如同人骑在马背上那么高，阳光在水柱顶上跳舞。

When the stopcock is opened, water flows from the top of the warmer column into the colder column

打开活塞后，水即由较热的水柱顶端流入较冷的水柱。

Results One ureterostoma leaked when the water volume reached 135 cm,1 leaked when it reached the 167 cm, 2 leaked when it reached 175 cm, and others didn't leak when it reached 197 cm.

结果 本组25例检测标本中，在水柱高度达到135 cm、67 cm、75 cm时输尿管末端开始出现漏水者各为1例、1例、2例，另外21例标本在水柱到达197 cm时输尿管末端仍没有出现漏水现象。

" Hong "……big day small angel for water pillar Frankputting the cloudy regions, gold color the flashlight ray of light ten thousandth s, from the water inside even if jumping outing a beauty, her crouch, were washed the affair for of water pillar the entrust rise, fall on first the regiment is white to resemble snow, gentle the gentle 's white cloud, she sweet and sweetly asleep, root does not knowing under she take placing of an an an an an an an an an an an a day, and already also not know her parents

& 哄&……擎天水柱直插云霄，金色闪光光芒万丈，从水中纵然跳出一个美丽的小天使，她蜷缩着，被冲天的水柱托起，落在一团白得像雪，柔得似絮的白云上，她甜甜的睡着，根本不知道就在她下面发生的事情，也不知道她的父母已经

This practice has certain limitation and cannot give full play to the substantial water columns of hydrants.

本文提出充实水柱可以大于规范要求的最小充实水柱，减少消火栓的设置数量。

WATER IN THE FORM OF A JET IS ONLY REQUIRED TO COMBAT A FIRE THAT CANNOT BE REACHED BY A SPRAY OR WHERE THE FORCE OF A JET IS NEEDED TO BREAK UP MATERIAL IN A DEEP SEATED FIRE SUCH AS MAY BE FOUND IN A HOLD FIRE.

水柱灭火只是用来灌救水雾灭火不能达到之火警，或是须要一支强的水柱去冲散位於深处的著火物体，例如货舱火警。

The results showed that removal effect of periphyton on nitrogen was significant.Cumulative removal ratio of nitrogen was up to 60%,the nitrogen concentration decreased from 5 to 2 mg /L or so within two weeks.Cumulative removal ratio of nitrogen was closely related with nitrogen concentration,working time and biomass of periphyton.

结果表明，附着生物对水体中的氮有显著的去除效果，半个月内，附着生物对水体中总氮的累积去除率可达60%，在有附着生物的水体中总氮浓度从5 mg/L左右下降到2 mg/L左右；附着生物对水柱中氮的累积去除率和水柱中氮的浓度、附着生物的生物量以及附着生物作用时间密切相关。

In the first cultivation stage,as relatively high concentration of phosphorus,phosphorus from water column was removed to a certain extent by periphyton.The end of the incubation,as low concentration of phosphorus periphyton releases phosphorus to water column instead of removal phosphorus from water,this may closely relate to the alkaline phosphatase secreted by periphyton in water body.

从培养过程中水体磷的浓度变化来说，培养初期，水体中磷的浓度比较高，附着生物对其有一定的去除作用；培养后期，水柱中磷的浓度比较低，附着生物不但不去除水中的磷，而且还向水柱中释放磷，这可能与附着生物向水体分泌碱性磷酸酶密切相关。

TO DIN respiratory valve, the valve plate must be removed between the shock thing.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
