== H2O ==水是H2O,氢分子和氧分子1。水是稍微极性(电荷)。表面张力和毛细作用是导致极性水分子的属性。表面张力是水分子抱住对方的财产。毛细作用就像是除水,攀缘在其它分子(如玻璃,塑料等)的表面张力。 翻译结果2复制译文编辑译文朗读译文返回顶部 翻译结果3复制译文编辑译文朗读译文返回顶部 ...
Abstract Rotational constants reported previously [J. Chem. Phys. 9 0, 5964 (1989)] for the C 2 asymmetric tops H2O–(CO2)2, D2O–(CO2)2, H2 18O–(CO2)2 and H2O–(13CO2)2 have been reanalyzed. It is found that the slipped parallel (CO2)2 subunit, instead of remaining planar...
𝑤¯w¯ (converted from the vertical pressure velocity) is the zonal mean vertical velocity. The dynamical heating includes the first three terms on the right side of Equation (1), which denote heating by the meridional component of the residual circulation, the heating/cooling by ...
In this work, a new equation of state for a H2–He–H2O–CH4 mixture is presented. The equation is optimized for the deep jovian atmosphere (∼100 bars) where the NASA Juno Microwave Radiometer (MWR) will probe. The methodology used is based upon that of Lemmon and Jacobsen (Lemmon, ...

and the supply elevation is between1984.9m and2283.9m. The recharge area is located in the mountainous area with the elevation of1984.9～2283.9m around the study area. The mixing ratio of cold water calculated by silicon enthalpy equation is between 71.9% and 82.4%. The heat reservoir temperatur...
He finallyabandonedthissuggestionaround 1822 but still insisted that the ammonia became oxidizedatthemomentofneutralizationby reacting with the solvent water. 他最终在1822年左右放弃了这个建议,但仍然坚持认为氨在中和时通过与溶剂水反应而被氧化。 Thus in the reaction between sulfuric acid and ammonia to gi...

Haematite (α-Fe2O3) has been extensively investigated as a photoanode in photoelectrochemical water oxidation, but the product O2 has a low economic value. Here we expand its applications to the production of value-added chemicals and report its ability to act as a versatile and efficient oxyg...
