查询词典 vapor

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。

The spacecraft's sensitive spectrometer was able to register the chemical signatures not only of water vapor but also of hydrogen cyanide, carbon monoxide, and carbon dioxide--all precursors of the more complex molecules that scientists think eventually gave rise to life on Earth.

斯必泽太空望远镜上敏感的光谱仪不但能够记录水蒸气的化学特征，还能够记录氰化氢、一氧化碳和二氧化碳的化学特征，这些都是更为复杂分子的初级粒子，科学家们认为是这些初级粒子最终导致了地球生命的产生。
