同时研究了反应气体流速对h _ 2s光催化氧化反应的影响， h _ 2s的去除率与流速成反比。 - In experimentation , the project adopts computer , data collection board , sensor and software . finally , the theory analsis is validated that the contact of noise elimination , velocity of flow , resistance loss
在试验中，采用了以计算机、数据采集卡、传感器和处理软件得到阻性消声器的动态特性，从而验证了阻性消声器的消声量、气体流速和阻力损失之间联系的理论分析。 - In order to otain high quality zno thin films , we , for the first time , employ the plasma enhanced chemical vapor deposition ( pecvd ) to prepare high quality zno thin film at low temperature using a zinc organic source ( zn ( c2h5 ) 2 ) and carbon dioxide ( co2 ) gas mixtures . the effects of the growing condiction and the native oxide layer of si substrate on the quality of zno thin films was studied in detail . to prepare p - zno and overcome the dufficulty of reverse due to the interaction between the n atomic , we obtain high qulaity p - zno by a easy way of thermal zn3n2
为了在低温下制备高质量的氧化锌薄膜，我们采用金属有机源和二氧化碳气源，首次利用等离子体增强化学气相沉积的技术在低温下制备了高质量的氧化锌薄膜，系统地研究了生长条件以及衬底表面氧化层对薄膜质量的影响，确定了生长高质量氧化锌薄膜的优化条件；为获得p - zno材料，克服在zno中掺n杂质间相互作用影响掺杂效率不易获得p - zno的困难，我们通过热氧化zn3n2的方法制备了p - zno ，获得了一系列研究结果： 1 、详细研究了气体流速比，衬底温度和射频功率实验参数对氧化锌薄膜特性的影响。 - It was still a technical problem on how to add the air to the reactor in so small pressure difference . in addition , the photocatalytic reaction efficiency was very low at the high speed . the reactor will be large , the price will be very high and the electricity will be enormously consumed during the photocatalytic - oxidation of h2s in the methane
主要原因是沼气中不含氧，使用时气体流速大，压差小，而用光催化氧化方法消除h _ 2s需要有相当量的氧参与，在压差很小的情况下，一次空气的加入存在技术困难；在高气体流速条件下，光催化效率低，若用光催化方法消除h _ 2s ，反应设备庞大，耗电量高，价格昂贵，农民难以负担。
