| 1. | Standard test method for water vapor content of gaseous fuels by measurement of dew - point temperature 露点温度法测定气体燃料中蒸汽含量的标准试验方法 |
| 2. | Do not apply when the surface temperature is less than 5 or less than 3 above the dew point of the air 底材温度不可低于5 ,而且至少应当高于空气露点温度3以上。 |
| 3. | Values of dew - point temperature and relative humidity are calculated automatically from the dry - and wet - bulb temperatures by a microcomputer 露点温度和相对湿度则由一部微型电脑从乾、湿球温度计算出来。 |
| 4. | Values of dew - point temperature and relative humidity are calculated automatically from the dry - and wet - bulb temperatures by a microcomputer 露点温度和相对湿度则由一部微型电脑从乾、湿球温度计算出来。 |
| 5. | The measurement results and uncertainty analysis shows that in the dew point range of - 25 ~ + 25 the uncertainty less than 0 . 04 测试结果和不确定度分析表明,该发生器在25 ~ + 25测量范围内,露点温度测量的不确定度不大于0 . 04 。 |
| 6. | Firstly , a dew - point control system was established , which can keep the dew - point of the supply air at a constant value range form - 10 ~ 45 首先建立的露点控制系统实验台,能够为实验提供露点温度在- 10 ~ - 45范围内湿度稳定的压缩空气。 |
| 7. | The surface temperature of the substrate should be at least 10 and 3 above the dew point . temperature and humidity should be measured in the vicinity of the substrate 底材温度10以上,比空气露点温度高出至少3 ,温度和相对湿度在底材附近测量。 |
| 8. | The main results are as follows : 1 . co and water vapor column contents retrieved from the solar absorption spectra are well related with the surface co concentration and surface dew point respectively 主要研究过程和结果如下: ( 1 )利用太阳吸收光谱反演得出的co柱总量与地面co浓度之间、水汽柱总量与地面露点温度之间存在着比较好的相关性。 |
| 9. | To avoid any condensation on the floor slabs in summer , the air supplied is kept at a dew point of 14oc to keep some reserve for the pick up of moisture in the room and to stay below the surface temperature of the ceiling 为了避免夏季楼板上的凝露,送进的新风保持在14摄氏度的露点温度,以保证能够除去室内湿气,并使其露点温度低于天花板的表面温度。 |
| 10. | Secondly , when the supply pressure is constant , experiments were carried out with different supply air dew - point and volume ratio of the system . then record the system whether occurring internal condensation or not as the experiment result 其次,当供气压力一定时,对不同容积比的气动系统,改变供气露点温度,进行大量实验,观察系统是否发生内部结露,记录实验结果。 |
