In the forth chapter, the mechanism of pyrimidine benzylamine compounds is studied by the conventional bioassay and biochemical methods based on probe compound 104-4. The results presented here indicated that the addition of 5 mg/L of 3 branched-amino acids to sorghum seedling cultures incubated in the presence of 104-4 completely alleviated herbicide-induced stem growth inhibition, but each of Val, Ile and Leu single is only partly effective in reversing 104-4-induced growth inhibition at the same concentrations.

By the testing means of electron-spectroscopy for chemical analysis , thermogravimetric analysis , differential scanning calorimetry , transmission electronmicroscopy , the results have shown that the emulsion polymerization in situ in the presence of nano-particle of calcium carbonate can happen smoothly and successfully and the surface of nano-particle of calcium carbonate have been capsulated by polymer of acrylates, which prevent from the agglomerating of nano-particles of calcium carbonate. Because the copolymer of acrylate has good compatibility with some plastics such as PVC, ABS, AS and so on, so the dispersion of nano-scale calcium carbonate as nanometer size in these plastics can be reached more easily and the effects of nanometer can happen.

通过X射线光电子能谱、热失重分析、动态扫描量热分析、透射电子显微镜等手段，证实在纳米碳酸钙原生粒子存在下，可以进行丙烯酸酯类的原位乳液聚合，乳液聚合顺利，纳米碳酸钙表面被丙烯酸酯类聚合物所包覆，使纳米碳酸钙粒子间的团聚不易发生，同时由于丙烯酸酯类聚合物与PVC、ABS、AS等极性聚合物具有较好的相容性，从而使纳米碳酸钙在聚合物基体中能达到纳米状态分散，从而发挥纳米效应。

Further aza-Wittig reactions of iminophosphorane 3 with aromatic isocyanates gave the carbodiimide s 4, which were reacted with secondary amines to give 2-dialkylamino-thieno[2,3-d]pyrimidin-4(3H)-ones 6 in the presence of catalytic amounts of EtO-Na+ in 58%～82%.

Nica . After some preliminary remarks, the writer proceeds: We first transmit to you the writing concerning the faith which was put forward by us, and then the second, which they have published after putting in additions to our expressions. Now the writing presented by us, which when read in the presence of our most religious emperor was declared to have a right and approved character was as follows:. As we have received from the bishops before us both in our first catechetical instruction and when we were baptized, and as we have learned from the Divine Scriptures, and as we have believed and taught in the presbyterate and in the office of bishop itself so now likewise believing we offer to you our faith and it is thus.

&经过一些初步意见后，笔者得益：&我们首先向你转递写作有关的信仰是我们提出的，那麼第二个，其中，他们先后发表后，在增补为我们的表情，现在的写作由美，当他看过，在香港大多数宗教皇帝被宣布为有权利，并批准了字的内容如下：，因为我们已经收到了来自主教面前无论是在我们的第一catechetical指示和当我们受洗，并作为我们了解到，从神诵经，因为我们相信并教导，在presbyterate中和办公室的主教本身，所以现在同样相信我们提供给你我们的信仰和因此，它是。

The passive range of Cr in HC1 would extend in the presence of PD. For Fe, PD acted as a cathodically controlled inhibitor.

PD增强Cr在盐酸中的钝化性能，对铁、镍的腐蚀属阴极型缓蚀剂。

Objective To study the antigenpresenting function of splenic dendritic cells in mice after hemorrhage plus closed fracture.Methods Splenic DCs were isolated 24h after hemorrhage plus closed fracture,then the ability to stimulate nonadherent splenocytes proliferation in the presence of conalbumin in vitro was detected,IL12 and IL10 levels in cell supernatants were measured by ELISA kits.
