"Madam Xiang" as "companion" Xiangjun, this article from the perspective of Madam Xiang Xiangjun missing write poetry, dark counterpart, complement each other, constitute a harmonious realm. Study on the "Hunan madam" focused on analytical Hunan's image and identity, you can interpret from "structural art and emotion art" the lady of Hunan, Hunan and reveal Xiangjun love between each other, always to show Qu Yuan the love of the motherland, the great personality of political ideals and the pursuit of independence don't move.

To examine the toxicity of residue of succinylcholine chloride (SCC), the residue of SCC from experimental mice killed by 2ml 10 g/L injection of SCC was determined by the method of H-NMR and the residue toxicity was tested. 60 mice divided into six groups, were given with SCC, 625, 62.5, 6.25, 0.625 mg/kg, administered orally by the dose of 50mg; The control group were fed with the same amount dose with distilled water; cyclophosphamide toxicity tests for the same amount of control group; Accumulation coefficient method was used to examine the coefficient using 40 mice. Results showed that the content of drug residue of SCC is about 4mg in an experimental mouse. A cute toxicity test showed the LD50 is about 79mg/kg, accumulation coefficient (k) is 0.67， less than 1.

Most steelmaking wastes contain a certain amount of CaO. To use these solid wastes, the effect of CaO in the preparation of Fe/FeAl_2O_4 by Fe_2O_3-Al_2O_3 electrolysis was thermodynamic analyzed. The results showed that CaO may react with Fe_2O_3 and Al_2O_3 to produce CaAl_4O_7, CaAl_2O_4, CaAl_(12)O_(19), CaFe2O_4, and Ca_2Fe_2O_5 in the process of the experiment. The formation of CaAl_4O_7, CaAl_2O_4, CaAl_(12)O_(19) can be inhibited by controlling the ratio of raw materials, and CaFe2O_4, Ca_2Fe_2O_5 can be electrolyzed by adjusting the electrolysis voltage. Combined with the calculation results, NaCl-KCl molten salt system was selected in this experiment. The mole ratio of NaCl to KCl was 1:1, and the optimal reaction temperature range was 800-900 °C. The molar ratio of Al_2O_3 to Fe_2O_3 was 1:2. The range of the theoretical decomposition voltage was -1.05~-1.21 V. Under these experimental conditions, the presence of CaO will affect the preparation process, but it will not affect the produce of Fe/FeAl_2O_4 theoretically.
