查询词典 water vapor

For example, if an open test tube with some water in the bottom is placed in a room in which the air is relatively dry, water vapor will diffuse out through the column of air in the test tube.

This study has hypothesized that high concentration of nitrate, acetic and chorine ions in the scrubbing water lowers the water vapor pressure which in turn reduces the relative humidity of the scrubber outlet from 90~100% to below 80%. As a result, nitric acid can't absorb water to grow into visible white smoke particles.

本研究推论白烟消失的原因是因为含有高浓度硝酸根离子、醋酸根离子及氯离子之洗涤水蒸气压变低，使得洗涤塔出口的相对湿度由90~100%降低至80%以下，因而使得硝酸无法反应及成长成可见之白烟微粒。

Newell, et al ., found 10 huge filamentary structures that are the preferable pathways of water vapor movement in the troposphere (the lower 10-20 km of the atmosphere) with flow rates of about 165 million kilograms of water per second.

纽维尔，等人，发现10个巨大的丝状结构，是最好的途径，水汽运动在对流层（下10-20公里的大气层）与流率约1.65亿公斤水每秒。

These results indicated that a well structured anatase TiO2 was obtained by impregnation method under 500℃. Flow rate, in the activity test, could be neglected for mass transfer effects. As a matter of fact, relative humidity played the most important role in this reaction. The highest removal efficiency was obtained while relative humidify of 56.8%. Water molecules are sources of ; however, excessive water molecules could inhibit reactions by competing activity sites with organic containments. In the regeneration test, photocatalyst could be reactivated through a running water vapor with UV light illumination process.

研究结果指出，以含浸法制备之触媒於500℃锻烧下，具有良好的锐钛矿晶体结构；另外在活性测试的部份，流量的增加，污染物之去除效果不受影响，所以本实验选择以200ml/min之流量可忽略质传影响；湿度扮演重要的角色，当RH=56.8％时去除效率最高，主要因水气是产生氢氧自由基的主要来源，但是过多之水气可能与有机物竞争触媒表面上的活性位置，因而抑制反应的进行；初使浓度对去除率之影响中得知，初使浓度的高低不会影响触媒对有机物的催化能力，实验使用之触媒量适合催化200~250ppm之有机物，可藉由增加触媒量提高对有机物之催化能力；此外再生的测试，触媒可经由连续曝水及紫外光的照射，使触媒恢复原有的活性，可再次利用。

自由水，水浮质，和水蒸气提高对压缩空气系统造成严重破坏。

Mutual dissolution of water vapor and methane in the ancient HTHP situation and the formation of bound water in reservoir bed compaction lithogenesis led to the absence of water layers in deep basin gas accumulation.

深盆气形成于高温高压的环境中，早期地层水因汽化而与甲烷气混溶，一部分随岩性变致密加厚水膜而成为束缚水，导致深盆气盆地内无水层。
