The inhibitive effect of 1, 2-benzenedicarboxylic acid on the absorption of N, P and K increased with its concentration rising. Low concentration of dibutyl phthalate increased the absorption of N, but decreased the absorption of P and K. Its high concentration restrained the absorption of N, P and K, while the low concentration of diphenylamine could stimulate the absorption of N and K, but restrain the absorption of P.

随着邻苯二甲酸浓度的增加，其对番茄幼苗根系吸收N、P、K的抑制作用增强；低浓度的邻苯二甲酸二丁酯可以促进番茄幼苗根系对N的吸收，抑制对P、K的吸收，高浓度时对N、P、K的吸收均起抑制作用；低浓度的二苯胺可以促进番茄幼苗根系对N、K的吸收，抑制对P的吸收。

In addition, ioding was found to be an efficient catalyst for the imino Diels-Alder reaction of N-arylimine and enol ethers and the reaction provided tertrahydroqinolines in good yields. One pot synthesis of tetrahydroqinolines from aldehyde, aniline and enol ethers was also achieved using iodine as the catalyst. The chemical yield of the"one pot"reaction was comparable with that obtained using preformed N-arylimine.

此外我们也发现碘能够有效地催化N-芳基亚胺与烯醇醚的Diels-Alder反应，以很高的化学收率得到了四氢喹啉衍生物，并且发现碘也能够直接催化芳香醛、苯胺、烯醇醚的三组分&一锅&反应，获得的化学产率与使用预制的N-芳基亚胺相当。

We adopt a similar discotic liquid crystalline synthesis way to synthesize target molecules 7, 11, 15, 19, 21 in this article. The target molecules have a central triphenylene core and different side chains including triphenylamine derivatives and carbazole molecules. We observe these molecules optical and electrochemical properties and the effect of hole-transport layers in organic light emitting diode.

本篇论文的研究主旨是采用类似盘状液晶的合成方式，以三伸苯作为分子的核心，藉由改变不同的三苯胺及咔唑醚基侧链来合成目标化合物7、11、15、19、21，并观察分子的光学性质变化，电化学行为，以及作为电洞传输材料在有机电激发光元件上的效果。

However, most of the urban residents can only live in the apartment buildings made of reinforced concrete without the natural beauty of bamboos, what's more unbearable is the "modern environment pollution" coming from formaldehyde, aniline and the radiation from electromagnetic waves.

然而大部分的城市居民都只能生活起居于钢筋水泥混凝土构成的公寓楼里，不仅要接受苏东坡所云&居无竹&的&俗&的生活方式，更糟糕的是要忍受和适应甲醛，苯胺，电磁波辐射等种种现代化环境污染。

With the aid of aniline blue staining, pollen tube growth in pistil tissue was observed in Arabidopsis thaliana, and the growth speed of pollen tubes in style and ovary were calculated, the results showed that the pollen tube grew faster as time goes on.

以模式植物拟南芥为供试材料，利用脱色苯胺蓝染色的方法观察了拟南芥花粉管在雌蕊组织中的生长情况，获得了花粉管从萌发到进入花柱和子房不同时期的生长速率，结果表明，花粉管在不同时期的生长速率呈现出逐步加快的趋势。

The pollen living ability declined with time prolonging and the best condition for pollination was 22~28℃and fresh pollen appearing .By means of benzidine- hydrogen peroxide reaction and aniline blue fluorescence method, showed that the stigma receptivity could teach to 12 days since flowering. Compared with self pollination, the pollen was easily adhered into sigma and the pollen tube was easily entered into style in cross pollination experiment.

通过联苯胺—过氧化氢反应法和苯胺蓝荧光法观察了柱头的可授性、花粉在柱头的黏附、萌发及花粉管的生长情况，结果表明：非洲菊柱头发育初期就具有可授性，可授期达12d ；杂交和自交相比，杂交的花粉比较容易黏附、花粉管进入柱头比较容易，二者存在花粉黏附数量和花粉管进入数量的差异。

To estimate the bioconcentration factor of benzene derivatives in fish by gas chromatography retention time, this paper measured the BCF of chlorobenzene, o-chloro-toluene, p-dichlorobenzene, m-dichlorobenzene, 1,2-dichlorobenzene, nitrobenzene, p-chloro-aniline, p-chloro-nitrobenzene, and 4-chlorodiphenyl in grass crap, and the t_R of test derivatives on the stationary phases of six kinds polarity.

为了用气相色谱保留时间估算取代苯类化合物在鱼体内的生物富集系数，测定了草鱼对氯苯、邻氯甲苯、对二氯苯、间二氯苯、邻二氯苯、硝基苯、对氯苯胺、对硝基氯苯、4-氯联苯9种取代苯类化合物的BCF和不同取代苯化合物在6种不同极性固定相上的tR，建立了tR与BCF的一元回归方程及tR一阶分子连接性指数(1XV)与BCF的二元回归估算方程。

TpRu(PPh3)(CH3CN)2PF6 (10mol%) catalyst effected the nucleophilic addition of water,alcohols,aniline, acetylacetone, pyrroles, and dimethyl malonate to unfunctionalized enediynes under suitable conditions (100 °C, 12 24 h) and gave functionalized benzene products in good yields.
