Under certain conditions, the activation and migration of soil Cd were accelerated by the interaction of Pb and Cd and increased Cd uptake by wetland rice. The organic-bound Cd in rizhosphere decreased by 90%. These phenomena illustrates that the interaction is very important for the transformation of soil Cd fractions. Meanwhile, the interaction distinctly affected the composition of roots secretion and their coordination abilities with heavy metals, causing clear variation to Cd amount in root cortex and middle columniation.

在一定的实验条件下,Pb和Cd的交互作用促进了Cd的活化与迁移,增加了水稻地上部分对Cd的吸收,使根际土有机结合态Cd下降了90%左右,表明交互作用对Cd形态的转化是一个重要的控制因素;同时交互作用对根系分泌物的组成及其与重金属的配位能力有着明显的影响,使Pb、Cd在根系皮层和中柱中Cd的含量有明显变化。

Wear and corrosion involve mechanical and electrochemical mechanisms, and the combined action of these mechanisms often result in significant mutual reinforcement. To measure the effect on wear-corrosion resistance of the chemical and abrasion wear separately at the same time, wear-corrosion synergism rate is selected to indicate the nature and degree of the chemical and abrasion wear.

腐蚀磨损是同时涉及力学因素和电化学因素的复杂的材料的流失过程,通常条件下,腐蚀磨损不是纯磨损和纯腐蚀的简单叠加,还有两者间的协同作用,为定量描述腐蚀与磨损的促进程度、进一步完善腐蚀磨损机理,本文利用腐蚀磨损协同作用率值的大小来分析腐蚀和磨损的交互作用程度,结果表明:本文制备的镀层,在5%H_2SO_4溶液中腐蚀磨损时,机械磨损是造成镀层表面材料流失的主要原因,腐蚀和磨损的协同作用为次要因素。

According to our results, since BaP increased the expression of COX2 and pp38 to reduce the osteoblast differentiation and this phenomenon can reverse by treatment of NS398, but not by treatment of SB203580, suggesting that COX2 activation plays an important role on osteoblast differentiation. Adlay could increase osteoblast differentiation, in co-culture system, and reverse the osteoporotic status in mice, would be a helpful healthy food for enhance osteoblast differentiation. However, about, TBT, we didn't have enough data to support its effect on the differentiation of osteoblast or osteoclast.

所以依据我们所做出的实验结果,虽然苯骈芘会增加COX2和pp38的蛋白表现,但造骨细胞的分化作用仍下降,但若同时添加NS398,则分化能力有恢复现象,这或许可推测说COX2活性在抑制造骨细胞分化上扮演了一个重要角色;薏苡仁在共同细胞培养可以增加造骨细胞的分化作用,且对骨质疏松状态的小鼠具有缓解的能力,因此或许是能促进造骨细胞分化的营养食品;至於三丁基锡由於实验的数据不多,推测其或许并不影响造骨细胞和破骨细胞的分化作用。

The structural and photocatalytic properties of TiO〓 as well as surface acidity were greatly improved by sulfation. SO〓〓/TiO〓 solid superacid with Hammett constant Ho less than -12.14 was prepared by treating the TiO〓 with 1.0mol. L〓 sulfuric acid solution and then calcining at 450℃ for 3h. When compared to unmodified TiO〓, the SO〓〓/TiO〓 superacid catalyst exhibited higher anatase content, smaller crystal size, higher specific surface area, centralized pore size distribution, and the blue-shifted band edge of uv-vis adsorption spectra. Furthermore, the SO〓〓/TiO〓 superacid also showed excellent reaction activity and stability for CH〓Br photocatalytic decomposition even under the moist reaction conditions. The apparent quantum efficiency of SO〓〓/TiO〓 was 10 times of that of TiO〓 catalyst for the photocatalytic degradation of bromomethane. Therefore, the SO〓〓/TiO〓 superacid catalyst is promising for practical application in environmental remediation.It was found that both L and B acid sites exist on SO〓〓/TiO〓 photocatalyst while only L acid sites on TiO〓 photocatalyst. On the basis of experimental results, the synergistic model of superacidic centers was proposed for SO〓〓/TiO〓 photocatalyst to explain the photocatalytic behavior and the mechanism of superacidifing effects, assuming that the adjacent L and B acid sites induced by SO〓〓 comprise cooperatively the superacidic center on superacid photocatalyst. The group cooperation of the superacidic center could strengthen the surface acidity, increase surface acid sites and the adsorbtion of O〓, promote separation of photogenerated electron-hole pair, enhance the interfacial transfer of charges and reversibility of water adsorption. Consequently the excellent photocatalytic activity, reaction stability and resistibility to humidity of SO〓〓/TiO〓 superacid photocatalyst may attributed to the group cooperated effect of the superacidic center on the photocatalyst.

The chemical activating mechanism of UA is that CG can stimulate pozzolanicity more effective than gypsum because of higher solubility and looser crystal structure; but CG has poor property on retardation setting, and this shortage can be solved by mixing with gypsum; CS can offer alkali activity, which can depolymerize silica and aluminum glass, and benefit for other activity methods and overcome the disadvantage of HF on setting time; Sodium sulfate improves early strength greatly but loses the final strength. NF can improve both early and final strengths.
