Styrene is an important organic raw material for chemical industry. Normally it is made by dehydrogenization of ethyl benzene at adiabatic and vacuum conditions.
苯乙烯是重要的有机化工原料，通常采用负压绝热脱氢法，然后再精馏分离获得高纯度的苯乙烯产品。
The invention also relates to the catalyst C and methods involving the cross-linking of silicon by dehydrogenization with condensation (anti-cling coating on paper).
本发明还涉及催化剂C和包含通过脱氢缩合交联有机硅的方法（在纸张上的非粘涂层）。
The fatigue life-spans of specimens after dehydrogenization heat treatment and crystallization heat treatment are all decreased observably, which is caused by the tension internal stress.
经过除氢热处理和晶化热处理的试样的疲劳寿命，与基底试样和镀态试样相比都显著降低，而热处理后试样疲劳强度的降低是由于镀层的内应力引起的。
