空气温度

In the stratosphere, the temperature of the ambient air usually decreases with an increase in altitude.

在对流层，空气的温度通常随海拔高度的增加而降低。

Relative humidity exceeding 50% at the maximum ambient temperature of +40℃.

安装地点的空气相对湿度在最高温度为＋40℃时不超过50％。

The ignition delay period is controlled by the fuel injection advance angle which is an important parameter. If the advance angle of injection is adjusted earlier, the density of the combustion chamber is small and its temperature is low, when the fuel is injected into the combustion chamber. So it needs long time to atomization.

喷油提前角是影响燃烧滞燃期的重要参数，喷油提前角的大的工况，燃油喷入燃烧室时缸内空气的密度小，温度低，燃油雾化所需时间长，sauter平均直径大，油滴汽化的表面积越小，所以油束雾化效果不好。

Oct.,2005. Results The monthly average concentrations of benzene series in six months after decoration changed obviously while the temperature and time changed.

结果苯系物浓度随时间、温度的变化有统计学意义，随装修后间隔时间的延长，空气中苯系物浓度逐渐下降，4个月后达到国家标准限值的要求。

This paper describes the oxidation behavior of boron carbide in air bythermogravity analyses method.The lowest oxidation temperature is 420+10℃.

本文介绍了碳化硼在空气中的氧化行为，用的是热重分析法，测定出碳化硼的最低氧化温度为 420±10℃，高于 560℃氧化加速。

The Borzoi enjoys being outside, in the fresh air and they do prefer the cooler temperatures over the warmer ones.

猎狼很喜欢室外活动，在新鲜的空气里，他们更喜欢低一点的温度。

The experiment results prove that the boiler coking is largely reduced and the temperature difference of two sides of horizontal gas-pass is very small, when the 330MW boiler operate, the pressure of primary hot air parison is controlled beyond 12.0～12.5KPa, the O2 content of air pheheater is controlled about 3.0%, the door of OFA is opened to 30%, the buffle of the inner secondary air sleeve is adjusted to the minimum, the outer secondary air swirling strength and the baffle of the outer secondary air sleeve is regulated to the maximum and the outlet temperature of pulvervised mill is kept in 70℃.

试验结果表明，330MW运行时，一次热风母管压力控制在12.0～12.5kPa以上、空气预热器实际氧量控制在3.0％左右、燃尽风门开至30％、内二次风量套筒挡板调整在最小、外二次旋流强度和外二次风套筒挡板调整到最大、磨煤机出口温度维持在70℃，此时锅炉结焦大幅度减轻，水平烟道两侧烟温差非常小。优化试验完成后，进行了单烧灵武烟煤对比，结果是：掺烧高灰熔点的银北煤后，炉膛结焦大幅度减轻，锅炉过热器减温水量较小，主蒸汽压力易提高，带负荷能力正常；再热器烟气挡板开度较大、减温水量较小；风机电耗较小。

Bunsen burner:a small laboratory burner consisting of a vertical metal tube connected to a gas source and producing a very hot flame from a mixture of gas and air let in through adjustable holes at the base.

本生灯：一个很小的实验室用灯，由一个竖立的金属管与一个进气源相连而成，通过由底部可调节孔进入的空气与气体混合可产生温度十分高的火焰。

An expression of the Bunsen solubility of air in 500cSt silicone at temperatures of 293.2 and 353.2 K and in the gas-pressure range of 0-350 kPa was determined....

获得了温度为293.2及353.2K，压力在0-350kPa范围内，空气在500cSt二甲基硅油中的本生溶解度表达式。

All of these inks require at higher temperatures for a long time drying, cured their ink film very hard, so they are better than dry air burliness envirogluvtm more, not only can resist solvents, petrol and clean solution corrision, and can avoid scratch and wear.

所有这些油墨都需要在较高的温度下进行长时间的干燥，固化后其墨膜非常坚硬，因此它们比空气干燥的油墨更加结实，不但能抵抗溶剂、汽油和清洁溶液的腐蚀，而且能避免划伤和磨损。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
