查询词典 dew point

Dew point is a temperature, but it measures the absolute humidity of air.

露点是个温度，但它表示空气的绝对湿度。

When this happens , the absolute humidity of the drying air has a dew point of -40oC.

此时加热空气的绝对温度是-40℃的露点。

When this happen s, the absolute humidity of the drying air has a dew point of -40oC.

此时加热空气的绝对温度是-40℃的露点。

Surface temperatures must be at least 3℃ above dew point to prevent condensation.

表面温度必须至少高于露点3℃以避免水汽凝结。施工时表面不得有冰膜。

Clean surface with a temperature above the dew point to avoid condensation.

工作表面要保持清洁干燥，温度要高于露点，相对湿度低于85

In condensate gas reservoirs,the effect of capillary condensation can affect the dew point of condensate oil gas system, i.

在凝析油气储层中，毛细凝聚作用会影响凝析气的露点，孔隙越细小，毛细凝聚作用越强。

The computational formula of dew point temperature was presented according to the physical feature of water vapor such as Michell's saturated water vapour pressure formula. Surface temperature inside wall body was also calculated. Then the comparison between them verified whether wall body has dew. At the same time, the temperatures of every material layer inside wall body were calculated. The partial pressures of saturated water vapour and actual partial pressures of water vapour for every material layer inside wall body were obtained. The two were compared so as to verify whether condensation appears inside wall body.

根据Michell饱和水气压计算公式等水蒸气的物理特性，给出了露点温度计算公式，再计算出墙体内表面温度，将二者进行比较，从而验证墙体是否结露；同时计算出墙体内部各材料层温度，求出墙体内部各材料层的饱和水蒸气分压力及各材料层实际水蒸气分压力，将两者比较，从而验证墙体内部是否出现冷凝。

The bubble point, dew point and critical point were determined for binary mixtures of 1 pentene and 1 hexene, and thus the problem that critical parameters are evaluated without accurate and reliable theory is solved.

测定了1－戊烯－1－己烯二元混合物在不同组成下的泡点、露点及临界点，解决了没有准确可靠的理论估算临界数据的问题。

Metal corrosion in sulfuric aeid edw point is a common and very serious harm go the corrosion forms, in a wide range of production in all aspects of life, especially in some specific process unit operation equipment middle.low-temperature corronsion dew point in the general industrial rurnace, boiler, fuel saving edvices, air preheater, heat exchangers, tower refrigeration systems, dust, garbage incineration furnace, sintering furnace flue and chimney acid plant and the wind tunnels of hypothermia sife, yes containing gurnace flue and chimney acid plant and wind tunnels of hypothermia site, yes containing acidic gases produced by the condensation of cold treatment from the local cold drinks along with the liquid in the device, lesding to a very serious material corrosion.

金属材料的硫酸露点腐蚀是一种常见的，危害十分严重的腐蚀形式，广泛的发生在生产生活的各个方面，尤其发生在一些特定的过程单元操作设备中间。低温露点腐蚀一般发生在在工业加热炉、锅炉、燃料节省器、空气预热器、热交换器、塔顶冷凝系统、除尘器、垃圾焚烧炉、烧结炉、烟道，烟囱及酸厂的引风管道等的低温部位，是含酸性的气体经由该产遇冷冷凝下来的冷饮液局部地随着于设备上，从而造成对材料极严重的腐蚀。

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

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.
