查询词典 selective

The inhibition mechanism of MoO42- was that MoO42- transformed the hydrate ferrous oxide deposition film from anions selective to cations selective,and the cathodic process of underscale local corrosion was suppressed when it migrated into OCC.Meanwhile, the migrated MoO42- resulted in increasing the impedance of the film on the substrate metal and so inhibited the anodic process of the corrosion reaction inside the OCC.

MoO42-的作用机制在于使水合氧化铁腐蚀膜由阴离子选择性变为阳离子选择性，H+可以从膜下扩散出去，而Cl-难以扩散到膜下富集，抑制了腐蚀反应的阴极过程；同时MoO42-迁入闭塞区后增大了电极表面膜层阻抗，抑制了腐蚀反应的阳极过程。

Results show that the type and the orientation of atriums have a great significance for the thermal environment of the rooms surrounding atriums in selective mode buildings. But in exclusive mode buildings, the main factor is the type of atriums. It is intended that the greenhouse effect of atriums should be aggravated in order to reducing the energy requirement in selective buildings in winter.

First, the significant of co-factor InsP6 and center water in the mechanism of auxins are explored by docking; second, the experiments that compared with the docking rusults of two situations involving fully rigid and selective flexible of active residue of the receptor TIR1 illuminate that selective flexibility docking by AutoDock4 reports more rational results, so that, AutoDock4 dockings are implemented with TIR1-Auxins; third, AutoDock4 docking by TIR1-Auxins-Aux/IAA illuminates that auxin as a molecular glue enhances the interaction between TIR1 receptor and Aux/IAA substrate by the weak interactions, such as hydrogen bond and hydrophobic interaction, furthermore, the weak interactions between receptor protein and ligands greatly influence on auxin activity of auxin ligands.

RESULTS:(1) ET-1 could increase total protein production, surface area, ERKs activity and ［Ca2+］i in cultured cardiomyocyte in dose-dependent manner at concentrations ranging from 10-9 to 10-7 mol/L. And this effect could be abolished by BQ123, an antagonist of ETA receptor, partly inhibited by PTX, but not by BQ788, an antagonist of ETB receptor.（2）The activation of ERKs and the increase of ［Ca2+］i induced by ET-1 were obviously inhibited by PD98059, a selective ERKs kinase inhibitor, and nifedipine, a calcium channel blocker, respectively. Both antagonists partially inhibited ET-1-stimulated cardiomyocyte hypertrophic response.(3) Staurosporine, a selective PKC inhibitor, could inhibit ET-1-stimulated cardiomyocyte hypertrophic response and increase of ［Ca2+］i, but not affect the activation of ERKs.
