Road driving anaogue test shows thai long time operation with high gum content gasolene will cause greal amount of asphalt like sediment depositing on internal surface or backof engine indution gas passage, muffler...
研究结果表明，胶质含量超过20mg／100mL时，随胶质含量的增加动力性下降。120h道路模拟试验证明，长期使用高胶质汽油会造成进气管、进气道和进气门背部生成大量沥青状沉积物，严重时影响汽油机的正常工作。
Results There were significant differences between gum-chewing group and control group in both first passage time of flatus, first defecation time (P < 0.01) and occurrence of complaints (P < 0.05).
结果口香糖实验组在排气时间、首次排便时间均明显早于对照组（P<0.01），术后6~24h恶心、腹胀等不适症状发生率低于对照组（P<0.05）。
