Itamin D from the skin and diet is metabolized in the lier to 25-hydroxyitamin D (Figure 1), which is used to determine a patient's itamin D status1,2,3,4; 25-hydroxyitamin D is metabolized in the kidneys by the enzyme 25-hydroxyitamin D-1-hydroxylase (CYP27B1) to its actie form, 1,25-dihydroxyitamin D.1,2,3,4 The renal production of 1,25-dihydroxyitamin D is tightly regulated by plasma parathyroid hormone leels and serum calcium and phosphorus leels.1,2,3,4 Fibroblast growth factor 23, secreted from the bone, causes the sodium–phosphate cotransporter to be internalized by the cells of the kidney and small intestine and also suppresses 1,25-dihydroxyitamin D synthesis.5 The efficiency of the absorption of renal calcium and of intestinal calcium and phosphorus is increased in the presence of 1,25-dihydroxyitamin D (Figure 1).2,3,6 It also induces the expression of the enzyme 25-hydroxyitamin D-24-hydroxylase (CYP24), which catabolizes both 25-hydroxyitamin D and 1,25-dihydroxyitamin D into biologically inactie, water-soluble calcitroic acid.2,3,4

从皮肤和食物来的维生素D在肝中代谢为25-羟基维生素D（图1），被用来决定病人体内维生素D情况的1，2，3，4；25-羟基维生素D在肾中被25-羟基维生素D1羟化酶（CYP27B1）转变为有活性的1，25-二羟基维生素D 。1，2，3，4由肾产生1，25-二羟基维生素D是被血浆甲状旁腺激素和血清钙，磷水平紧密调节。1，2，3，4由骨分泌的成纤维细胞生长因子23使钠磷协同转运蛋白被肾和小肠细胞内化及抑制1，25-二羟维生素D合成。5 在1，25-二羟基维生素D作用下肾和小肠吸收钙及磷的效率增高(图1)。2，3，6 它也包括25-羟四- 24 -羟化酶的表达(CYP24)，且将1，25二羟基维生素D和25羟基维生素D异化成无生物活性，水溶性的维生素D3-23羧酸。2，3，4

In order to save water and reduce polluted water discharge,we use elliptical tube in rectangular steel fin tube which is treated in hot dipping zinc and use force cooling by blast axial flow fan to condensate the air in tube then return the condensate to boiler to form a closed circuit ,thus replace conventional water cooling tower.

采用椭圆管穿矩形钢翅片经热浸锌后组装的冷凝翅片管束，用鼓风式轴流风机强制将乏汽在管内冷凝成水返回锅炉形成闭路循环使用，从而可以取代常规开放式水冷却塔，极大地节约汽轮机运行的耗水量和污水排放量，对环境保护起到了积极的作用。

As for the drop-shaped pearl is because when the water can not be attached to the lotus leaf surface, due to the role of the surface tension of water molecules to make water droplets unite into a ball.

至于下降形珍珠，是因为当水不能附加到荷叶表面，由于水分子的表面张力的作用，使水滴凝聚成一个球。

The fluid geochemistry research bears out the ratio of W/R becomes more few from epithermal to porphyry.

成矿流体地球化学研究表明，大气降水在成矿系列中起到了重要的作用，水/岩比值由浅成低温热液低硫型→浅成低温热液高硫型→斑岩型有变小的趋势。

HD-G1 combination of professional weight-loss equipment science and acupuncture meridians of Chinese medicine of physical medicine, application of modern computer technology, electronic pulses through the process control, simulated acupuncture massage acupuncture points, so that the body-related device dirty to produce physiological responses, effective mediation of biological computers and metabolism, increased lactate dehydrogenase activity in the human body and completely adjust endocrine, improve the body metabolism, slow down the speed of glucose into fat, especially fat metabolism play a role in the decomposition will enable most of the three original fat acid glyceride hydrolysis into fatty acids and glycerol, and made to leave the fat cells, through a series of special decomposition pathway, the best carbon dioxide and water into energy is being consumed.

Through the study of characteristics of reservoir combination in sequence framework, we learned that source rocks mainly develop in transgressive system tract, reservoirs in highstand system tract, and mudstones developed near maximum flooding surface have good sealing ability for sandstone in transgressive system tract and highstand system tract.

通过层序格架内的成藏组合特征研究可知，烃源岩主要发育于水进体系域，储层主要发育于高位体系域，最大湖泛面附近发育的泥岩对水进和高位体系域的砂体都有较好的封闭作用。

The process of sand absorption is:(1) the vibration head vibrates and losses the sand layer, and supply high pressure air into the sand absorption head;(2) the high pressure air generates negative pressure in the sand absorption pipe when it is discharged out from the sand absorption;(3) the sand absorption head and the vibration are shifted downwards and maintains the water flow straightly.

取砂土的过程为：(1)振动头振动松散砂土层，同时向吸砂头供入高压空气；(2)高压空气通过吸砂头从排砂管向上排出的过程中，在吸砂管内产生负压，吸砂管将管口处的水和砂土吸入到吸砂头内，在高压气流作用下，吸砂头内的砂、水和气混合而成的三相流通过排砂管排出到受砂船上；(3)在吸砂的过程中，适时地将吸砂头和振动头下移并保持钻孔套管中的水流畅通。
