Study on synthesis of maleic ( 2-2 ethyl hexyl ) ester by HWP

杂多酸催化合成马来酸（2-2乙基己基）酯的研究

Carbon stock in HWP in 2003 estimated using three accounting approaches and FAO data is 2 ~ 7 times of China 's data set .

用FAO数据计算我国2003年碳贮量，其结果是我国统计数据的2~7倍。

Penetrating Agent T was synthesized with maleic anhydride and secondary octanol as raw materials , by taking HWP as catalyst .

杂多酸（HWP）为催化剂，以顺丁烯二酸酐与仲辛醇为原料催化合成渗透剂T。

Results show that SiN films with a low hydrogen content can be prepared by HWP CVD at a higher rate and lower substrate temperature , and the main bond mode in the deposited SiN films is Si & N stretching mode .

结果表明，采用HWPCVD技术能在低衬底温度条件下以较高的沉积速率制备低H含量的SiN薄膜，所沉积的薄膜主要表现为Si&N键合结构。

A novel 2 × 2 optical switch , which consists of phase spatial light modulator ( PSLM ), polarizing beam - splitter ( PBS ), mirror , half-wave plate ( HWP ) and quarter-wave plate ( QWP ), is proposed .
