The invention provides feed. The feed comprises wheat, bean pulp, fish meal, calcium hydrophosphate, salt, L-carnitine, chromium nicotinate, conjugated linoleic acid, vitamin C and traditional Chinese medicine composition feed additives used for improving the meat quality of meat ducks. The feed has low-toxicity, side-effect-free and residue-free effects and can improve the meat quality of the meat ducks significantly.

The invention discloses a novel aluminum alloy smokeless two-acid polishing additive and a preparation method thereof. According to the additive, a solution composed of phosphoric acid and pyrophosphoric acid in a certain mass ratio is used as a solvent, sodium molybdate is used as a corrosion inhibitor, copper sulfate and ferric sulfate are used as sensitizers, polyether is used as a dispersing agent, and nicotinic acid is used as a complexing agent. The preparation method comprises the following steps: adding certain amounts of sodium molybdate, copper sulfate, ferric sulfate, nicotinic acid and polyether into the phosphoric acid-pyrophosphoric acid mixture, and dissolving by heating and stirring. The additive does not generate oxynitride yellow smoke or other gaseous pollutants in the traditional three-acid polishing process, thereby preventing the polishing from damaging the human body and environment; and the polishing quality of the additive is comparable with that of the three-acid technique, and thus, the additive is a novel environment-friendly high-efficiency aluminum alloy two-acid polishing additive.

The invention relates to an electronic cigarette liquid, a preparation method thereof and a novel acid for preparing a nicotine salt and an electronic cigarette. The electronic cigarette is prepared from the following raw materials in parts by weight: 1 to 5 parts of nicotine, 2 to 10 parts of organic acid and 50 to 300 parts of organic solvent, wherein the organic acid is any one or a mixture ofnicotinic acid, parafluorobenzoic acid and para aminobenzoic acid. The electronic cigarette is prepared through reaction of the nicotine and a specific type of organic acid in the organic solvent. Compared with other existing electronic cigarette liquids, the electronic cigarette liquid disclosed by the invention has the advantages of lower nicotine salt concentration (the content of the nicotineis lower than or equal to 20mg / mL), better smoking feel, unique atomizing effect and smoking feel, and certain health care function.
