湿度

A greened roof is a natural air-conditioning,the roof is greened by theranspiration of the plants and the transpiration in green roof to increase air humidity, lower ambient temperature, reducing heat radiation, thus easing Heat island effect of the city .

一个绿化屋顶就是一台自然空调，屋顶绿化通过植物的蒸腾作用和屋顶绿地的蒸发作用，增加空气湿度，降低环境温度，减少热辐射，从而缓解城市的局部热岛效应。

But the concrete is non- one kind homogenizes the fragility material, under having certain temperature and humidity situation, the concrete is hardened and produced the volume out of shape, he is out of shape and inconsistent because of making up the material of the concrete, restrain from, produce initial stress each other, cause between aggregate and stone bonding surface of cement or cement produce the very small crack between the stone,These cracks are irregular, discontinuous too, under the influence of external factor, may also develop into a macroscopical crack.

但混凝土是一种非匀质脆性材料，在具有一定的温度和湿度情况下，混凝土硬化并产生体积变形，由于组成混凝土的材料其变形不一致，互相约束产生初始应力，造成在骨料与水泥石粘结面之间或水泥石本身之间产生微细裂缝，这些裂缝既不规则，也不连贯，在外界因素影响下，还可能发展成宏观裂缝。

Hooding and sleep, apart from the result of a lack of oxygen caused by breathing difficulties, confused things, a large number of water vapor exhaled from the mouth also a significant increase in the humidity inside the quilt, blanket a good micro-climate within the rapid destruction of the body skin, can become uncomfortable.

蒙头而睡的时候，除了因氧气缺乏而造成呼吸困难、头昏脑胀外，从嘴里呼出的大量水汽也使被窝内的湿度急剧加大，被窝内良好的小气候迅速遭到破坏，全身肌肤都会变得不舒服。

All the samples were placed in incubator at a humidified atmosphere of 5% O2 at 37 ℃ for 21 days.

各组置入37 ℃、体积分数为5%的CO2饱和湿度培养箱中培养21 d。

The meter can be used withlinear output features sensor or other measuring as measuring and display of pressure, weight, speed, frequency and humidifies.

产品适用于各种具有线性输出特性的传感器或其他测量设备，如压力、重量、速度、频率、温度、湿度等的测量显示

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。
