THE ROLE OF CARBON TETRACHLORIDE IN THE COMBUSTION PROCESS OF METHANE Ⅰ.

四氯化碳在甲烷燃烧过程中的作用Ⅰ。

A study of the effects of carbon tetrachloride on burning velocity and flame temperature in methane combustion has been made.

少量的四氯化碳显著降低甲烷-空气混合物的燃烧速度，但并不显著改变火焰温度。

The results showed that the initial temperature of methanation is different for the carbonaceous phases with different stability.

研究结果表明，不同稳定性的碳相在氢气氛下的起始甲烷化温度是不一样的，构成碳纳米管主体的六元环的碳，较之类似活性碳的杂形碳以及主要由五元环和七元环构成的碳纳米小颗粒，在氢气氛下是较为稳定的。

Results The extract remarkably inhibited the contraction caused by histamine and acetylcholine, as well as the ovalbumin sensitized allergic constriction of isolated ileum smooth muscle of guinea pigs. It could inhibit the increase of capillary permeability induced by acetic acid in mice, inhibit the mice paw edema produced by carrageenin and reduce the production of PGE 2 in inflammatory tissues.

结果：辛夷二氯甲烷提取物对组胺、乙酰胆碱（Ach引起的豚鼠离体回肠收缩具有显著的抑制作用，并能抑制卵白蛋白所致的豚鼠离体回肠过敏性收缩，对HAc引起的小鼠腹腔毛细血管通透性增高具有抑制作用，能显著抑制角叉菜胶引起的小鼠足肿胀，并减少前列腺素E2（PGE2）在炎症组织中产生。
