诱导物

In the wet-process phosphoric acid production from the Hubei phosphate ore, one of the bothersome problems is that potassium fluosilicate and sodium fluosilicate scales are liable to form on the filtration system owing to its high potassium and sodium content, which greatly restrains the application of Hubei phosphate ore.

本文首先采用人工冷却系统模拟湿法磷酸生产的真空过滤系统冷却过程，研究垢物的析出规律，实验结果得知：垢物的主要成分为氟硅酸钠和氟硅酸钾，氟硅酸钠首先析出，结构致密，其次是氟硅酸钾，最后是二水硫酸钙，氟硅酸钠对氟硅酸钾有很强的结晶诱导作用；然后在三种生产中常用的不同的材质钼二钛、聚氯乙烯和聚四氟乙烯表面进行结垢试验，发现聚四氟乙烯表面最不易结垢，而在钼二钛表面最易结垢。

结果表明：①葛根显著降低地塞米松诱导的胰岛素抵抗大鼠血清胰岛素水平和胰岛素抵抗指数，升高胰岛素敏感指数，改善大鼠的胰岛素抵抗；②葛根显著改善胰岛素抵抗大鼠的糖耐量，但对四氧嘧啶糖尿病小鼠的糖耐量没有明显的作用；③葛根显著增加胰岛素抵抗3T3-L1脂肪细胞对葡萄糖的摄取，改善地塞米松诱导的3T3-L1脂肪细胞的胰岛素抵抗；④葛根能促进HepG2肝癌细胞过氧化物酶体增殖物激活受体γ与靶基因的特异DNA序列结合，对PPARγ及其下游基因的转录具有激活作用；⑤葛根能够促进PPARγ及其下游基因脂肪酸结合蛋白(aP2)、脂联素mRNA的表达。

Acicular ferrite microstructure in micro-alloyed steels, which nucleates around non-metallic inclusions, especially oxide inclusions, has high strength and good toughness and possesses strong grain-refining ability by itself. The ultra-fine grained steel with excellent weldability is likely to be produced by forming in materials a great number of fine and dispersive micro-inclusions which is helpful to induce AF to nucleate around them through oxide metallurgy technology.

微合金钢针状铁素体组织强度高、韧性好，在奥氏体晶内非金属夹杂物上诱导形核，具有很强的自身细化晶粒的能力，通过氧化物冶金技术控制钢铁材料形成大量细小、弥散，具有诱导AF形核能力的有益微夹杂物，有望获得焊接性能优良的超细晶粒钢。

It was observed that not only histidine, but also histidine-Co and histidine-Ni could induce and substitute some Cu and Zn from Cu_2Zn_2SOD, eventually influence the activity of this metalloenzyme. Histidine- metal ion complexes have stronger ability than histidine to displace the bound metal ion from SOD. In addition, the amount of foreign metal ion binding to the SOD was less than that of metal ion lost from SOD. It obviously means that there was apoenzyme in the solution.

实验结果表明： Cu2Zn2SOD酶不仅与组氨酸，而且还可以与组氨酸－CoⅡ）和组氨酸－Ni(Ⅱ相互作用，Cu2Zn2SOD酶中的部分Cu和Zn被诱导和置换出来，并相应地影响了酶的活性；组氨酸－金属离子配合物的作用比组氨酸强，酶活性降低也更明显；酶中结合的外来金属离子的量比从酶上被诱导和顶替下来的金属离子的量要少，说明在溶液中有脱辅基酶的存在。

For the case of thermo-caused micellization, as temperature is lifted to above the LCST (about 35.2℃), micellar structures having hydrophobic aggregates of PNiPAAm grafts as the core and solvated HEC and PAA chains as the shell can be achieved because of the hydrophobic interaction of PNiPAAm grafts.
