PH是壁挂炉采暖最大功率值，这个值的范围也是1-99之间，cn一般代表是中国！出现E1、E2、F2、c0等显示：这是故障代码，提示电器有故障和大致的部位，不能正常工作。由于每种电器的故障代码都不同，可以先看看说明书。里面一般都有故障代码表，看有没有这种故障和对应的故障提示。如果查不到，或没有说...

We present a microkinetic model for CO(2) reduction (CO(2)R) on Cu(211) towards C2 products, based on energetics estimated from an explicit solvent model. We show that the differences in both Tafel slopes and pH dependence for C1 vs C2 activity arise from differences in their multi-step...
Vanadium-aluminum oxide catalysts for propane oxidative dehydrogenation (ODH) are investigated with respect to their physico-chemical properties and catalytic activity as a function of the co-precipitation pH. Modifications of the specific surface area, the particle size distribution, and the chemical nat...

The complexes (PhCOO) 2(PPh 3) 2(CO) 2Ru ( 1) and ( p-MeC 6H 4COO) 2(PPh 3) 2(CO) 2Ru ( 2) have been made by treating tricarbonylbis(triphenylphosphine)ruthenium(0) with benzoic and p-toluic acid, respectively. An X-ray diffraction study of 1 has revealed an octahedral geo...

解析 ph-CH2CO-ph中,左边的苯基直接连在烷基上(-CH2-),烷基是给电子基团,所以是连在给电子基团上.而右边的苯基直接连在羰基上(-CO-),羰基是吸电子基团,所以是连在吸电子基团上. 分析总结。 phch2coph中左边的苯基直接连在烷基上ch2烷基是给电子基团所以是连在给电子基团上...

水化学成份中pH,CO_3~(2-),HCO_3~(1-),Ca~(2+)和Mg~(2+)的测定,是水分析中通常要测定的常规项目.习惯上用一份溶液测定pH,一份溶液测定CO_3~(2-),另一份溶液测定HCO_3~(1-),Ca~(2+)叶和Mg~(2+).我们采用酸度计指示终点的电位滴定法.在同一份溶液中测定pH,CO_3~(2-),和HCO_3~(...
