According to model, lead zinc ore bodies of mineral deposit, celestite ore bodies and gypsum ore bodies are distributed by the incomplete dome shape. The sandstone type ore bodies like a curved surface shape, is on the top, wide distribution, which like the top cover of a mushroom. The limestone breccia type ore bodies, under the sandstone type ore bodies, with mostly irregular vein shape, lens body shape, locate at the root of the mushroom. Gypsum and celestite ore bodies, accompanying with limestone breccia type ore bodies with the shape of vein, lens body, distribute under the sandstone type ore bodies.

In the middle and later period of Ming Dynasty, the political system changed a lot under the influence of Confucianism, that is a part of ethnic minority deeply influenced by Confucianism began to have the political reform, that is abolishing the native chiefdom system and bringing the ethnic minorities under unified provincial administration.

在清代268年的统治中，虽然没有出现像明朝那样大规模的政府组织的移民，但由于清朝时期人口总数增大，在明朝大规模移民云南的基础上，内地与云南的交往增加，中原地区人多地少的矛盾日益突出，清朝云南矿业发达，所以，清代以各种形式进入云南的中原人口不下百万。

Under suitable infusion rate (30 mg/kg/hr), the physiological conditions remained stable for 5 hr, while the results suggested that the high dose and vehicle were not appropriate dosages for a stable anesthesia. Also, fMRI activations of the contralateral primary somatosensory cortex were readily observed under low dosage of α-chloralose infusion.

在低剂量的α－氯醛醣麻醉下，动物的生理状态可以维持稳定达5个小时，并且在fMRI的实验中得到清楚的BOLD反应，但是对照组以及高剂量的老鼠，在这样长时间的麻醉中，生理及麻醉状况无法维持稳定。

First, a chlorinator was self-designed in this paper, and dichloride of 2-methyl-1-propene was synthesized by 2-methyl-1-propene reacted with chlorine fast in this reactor. By means of the Orthogonal Experiments design and single factor experiments, the influence of several reaction variables on the yield were examined and the optimum reaction conditions under the intervallic operation were obtained, the yield and selectivity of dichloride of 2-methyl-1-prop-ene were more than 65% and 80% respectively.
