The result showed that the dry weight of plant and the weight of fruit per plant were increased by compound DTA-6 + Mo, and the yield was improved. The amount of water-soluble sugars and water-soluble protein and free amino acids were increased, thus improved the nutritional quality of the bean. At the same time, the activity of root was improved, and the content of chlorophyll and the photosynthetic rate were increased.

The observation and monitoring were carried out for one year. Improvements resulted from the project include suspended particles, transparency, concentration of chlorophyll A, total organic carbon, total nitrogen. Factors that did not show obvious improvement include electrical conduction, concentration of nitrate nitrogen, ammonia nitrogen, nitrous nitrogen, phosphate salts. Finally, factors that were influenced by environment include water level, temperature, pH, total phosphorus, chloride salts.

历经一年的试验，因设备投入而改善之因子为溶氧、浊度、悬浮固体、透明度、叶绿素a、总有机碳、总氮等7项，无明显变化之项目为导电度、硝酸盐氮、氨氮、亚硝酸盐氮、磷酸盐等5项，受环境影响因子为水位、水温、pH、总磷、氯盐等5项。

The result showed that not only the seed-stem germination of XinXuan048 and ZM8316 was earliest but also the germination rate highest,the rooting power strongest ,the growth of seedlings rapidest and the chlorophyll content of seedlings leaf highest .

结果表明，新选048、ZM8316种茎发芽最快，发芽整齐，发芽率高，种茎可溶性糖含量最高，发根力强，根数多，根系活力强，幼苗茎叶生长快，叶片叶绿素含量高；其次是辐选01、华南124和新选056。

The experiment used Four kinds of farmland common herbicides (Fenoxaprop、Clethodim、Glyphosate、Fenoxaprop-p-ethl),MDA content、Leaf cell menbrane permeability、Chlorophyll content were tested under three treaments of different medicaments and combined with the growth index.The results showed:(1) When they were used in normal concentration,growth and the others physiological indexes had obviously different under four kinds of herbicides treatments.According to effects of four herbicides on Zanthoxylum bungeanum Maxim ,the effect of Glyphosate randed first,the rest ones were Clethodim、Fenoxaprop-p-ethl and Fenoxaprop.

以农田中常用的6.9%骠马水乳剂、24%收乐通乳油、88.8%飞达红水溶性粒剂、6.9%威霸水乳剂等四种除草剂为供试对象，通过对各药剂的三种浓度处理下花椒叶片中丙二醛含量、叶片中叶绿素含量、叶片中细胞膜通透性的测定，再结合生长量指标进行分析研究，结果表明：(1)在常用浓度下，四种除草剂对花椒生长量及各生理指标的影响有很大差异，飞达红影响最大，依次为收乐通、威霸、骠马。

The results showed that the purslanes which were under 100% light transmissivity growed faster than 25% light transmissivity.As well as the FW and DW of overground parts and roots,the soluble sugar content,soluble protein content the value of chl a/b,there were significant difference with 100% light transmissivity.

结果表明：在100%透光条件下，马齿苋植株地上部和地下部干鲜质量、植株高度、可溶性蛋白、可溶性糖含量和叶绿素a/b值均与25%透光率条件存在显著性差异。

After 14D and 28D, Observe the color of the leaves,Count the number of leaves and respectively measure the seedling's height、root long、wet weight、dry weight、relatively water content、chlorophyll content、soluble sugar content、proteid content、nitrate reductase activity and Peroxide enzyme activity to discuss the effect of each element to the tomato seedling.

为材料，进行缺氮、缺磷、缺钾、缺铁的溶液培养，分别在培养14d和28d后观察其叶色，计算叶数并测定了各缺素植株的株高、根长、鲜重、干重、相对含水量、叶绿素含量、可溶性糖含量、蛋白质含量、硝酸还原酶活性和过氧化物酶活性。

The results showed that contents of amino acids and soluble sugars decreased, while chlorophyll increased, and that of polyphones first decreased and then increased with the rising of shaping temperature.

品质成份分析结果表明，随做形温度的升高，氨基酸、可溶性糖含量下降，叶绿素则相反，茶多酚呈先减后增趋势。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
