A bigger challenge was installing lights and projectors that would automatically disconnect if chemical sensors detected dangerous gases, including carbon monoxide, methane and sulfuric acid.
一个更大的挑战是安装电灯和放映机，如果化学物质感测器侦测出危险气体(包括一氧化碳、甲烷和硫酸)，这些电灯和放映机能够自动断电。
Methane sulphonic acid (MSA) has the right combination of properties for electroplating baths containing lead, tin, copper, nickel and some precious metals.
在含有铅、锡、铜、镍和一些贵金属的电镀池中，甲磺酸(msa)是一种很好的电解质。
But the research in the effect of the volume ratio of acid phase to methane phase on a removal efficiency of organic materials are still deficient.
但酸相和甲烷相之间的容积比对有机物去除率的影响的研究尚很欠缺。
The assistant stabilizing agent is dibenzoyl methane, stearic acid, polyethylene wax or compound thereof.
辅助稳定剂为二苯甲酰甲烷、硬脂酸或聚乙烯蜡或其复配物。
These calculations also indicate that the dimer structure is a reasonable model for the associated molecules of methane - sulfonic acid in the liquid phase.
对单体和二聚体的甲基磺酸进行了简正坐标计算，结果表明二聚体结构是液态甲基磺酸聚积态分子的合理模型。
Acetic acid concentrations were higher in early than nc, in late that due to the depletion of methane produced are little difference.
乙酸浓度在前期均高于对照组，在后期因甲烷产生而消耗殆尽后则相差不大。
Acetic acid concentrations were higher in early than nc, in late that due to the depletion of methane produced are little difference.
