The negatively charged sulfonic acid groups was readily introduced through the reaction of the terminal anhydride groups of the anhydride-terminated hyperbranched poly precursor with the amino groups of sulfanilic acid before chemical imidization.

研究表明,在聚合过程的聚酰胺酸阶段,采用过量的邻苯二甲酸酐或苯胺对超支化聚酰亚胺的端氨基或端酸酐基团进行的封端改性切实可行,改性反应可进行地相当彻底。

The investigation of the electrochemical properties of these polymers reveals that the HOMO levels of PFTP11 and PFTPA were significantly higher than that of PFP due to the introduction of triphenylamine group, suggesting the improvement of hole-transport capability of them.

通过对其电化学性能进行测试可知由于三苯胺基团的引入聚合物的HOMO能级明显提高,这意味着聚合物的空穴传输能力得到了有效的改善。

Experimental results showed that the hydrogenation degree can be enhanced significantly by the addition of triphenylphosphine. When the molar ratio of TPP, TPPTS and Ru is 2:5:1, 89% hydrogenation degree can be achieved after 12 h under reaction conditions of 5.0 MPa and 150~C.

The presence of the fungus in the leaf tissues was studied by means of paraffin-cut section dyed with aniline blue. The results showed that the fungus was observed on the surface and in inner tissues of leaves, indicating that Trichoderma longibrachiatum strain CSN-18 could establish colonization in ground portion of tea seedlings as an endophyte.

通过石蜡切片和苯胺蓝染色,在已接种的茶树组培苗的叶片内部组织中可观察到木霉的存在,从而证明了木霉能够在茶树地上部组织内定殖,是茶树的一种内生真菌。

In the present study, it was discovered that P6 could degrade aniline blue on the 4th days and could assemble tannic acid on the 10* days when grown in BM plate, which indicated it could excrete extracellular peroxidases and trace laccase. The peroxidases activities reached the highest on the 4th days in liquid culture.

本研究发现其在BM平板上生长时,4天即可产生明显的苯胺兰脱色现象,10天时可产生弱的鞣酸聚集现象,揭示P6可分泌高活性的过氧化物酶和微量的漆酶。

An oncomelania killer is prepared through preparing mother liquid A from hydrochloric acid or 50 wettable powder of nicotinani line sul fate and dechlorinated water , preparing method liquid B from raw powder extracted from Huangqieguo fruit or bardabosnut seed and dechlorinated water , proportionally mixing them together and adding dechlorinated water for different concentrations .

灭钉螺剂及其生产方法,是将盐酸或硫酸烟酰苯胺50%可湿性粉剂加去氯水配成母液,再将由黄茄果果实提取的原粉或由麻风树籽提取的原粉加去氯水配成母液,将两母液按比例混合再加不同量的去氯水配成不同浓度的灭钉螺剂。

Place 5 ml in a test-tube immersed in iced water, add 0.4 ml of a 100 g/l solution of potassium chloride R, 0.1 ml of diphenylamine solution R and, dropwise with shaking, 5 ml of nitrogen-free sulphuric acid R.
