4.Because the carbonyl in its structure is with strongly absorb-electron effect, so it is a kind of non-proton polarity solvent with high boiling point, high flash point and low melting point, use conveniently for many processing operation such as filtration, distillation, solvent extraction, and so on; it is with very low toxicity, so the harm to human body is inappreciable, and reduce the environment pollution; due to its very strong dissolvability, it can dissolve organic matter, inorganic matter, resin, polymer, etc., and activate all kinds of reagent, mix to dissolve the other high boiling point solvents; it is with very good stability, it is stable under the hot strong alkali and acidity condition, it is with water-resistance and light, oxygen stability.
9.The thesis bases on the advanced methods of in-country and overseas in researching the dissolved inorganic carbon, particulate inorganic carbon in mixing zone. We adopted the method of observing consecutively by using ten ships, and described the TSS, DIC, PIC% of Huanghe estuary water in August and September, 2003, and described the PIC% of surface deposit matter in September, 2003 meticulously.
10.The carbon (C) and N originating from litters might take different pathways during decomposition and be either incorporated in stabilized (remaining) soil organic matter, released as CO_2 and N_2O or transported to the mineral soil as dissolved organic carbon (DOC), dissolved organic nitrogen (DON) and dissolved inorganic nitrogen (DIN).
