The results indicated as pH values in the range from 4.50 to 7.50, the volume and dry weight of root increased as pH values increased, as well as AAAR,TAAR. The relationship of nicotine and total nitrogen accumulation with pH values was parabola,the functions were Y=-61.429X2+391.17X-162.8 (F=l 8.45), Y=-24.3X2+154.88X+52.7 (F=14.40**) respectively. When pH value got rise to 7.50, the accumulation of nicotine and total nitrogen attained the highest .

主要研究结果如下： 1 不同pH值(4.50、5.50、6.50、7.50、8.50)对烤烟根系发育、根系吸收面积以及对烟叶烟碱、总氮、蛋白质和多酚物质积累影响的研究结果表明pH值在4.50～7.50范围内，根系体积和干重都随着pH值上升而增加，AAAR、TAAR也随着升高，烟叶中烟碱、总氮累积量随着pH值上升而增加，烟碱和总氮累积量与pH之间呈抛物线关系，关系式分别为Y=-61.429X~2+391.17X-162.8，F=18.45~；Y=-24.3X~2+154.88X+52.7，F=14.40~，pH值对烟碱和总氮累积量的影响存在极显著差异，当pH值升至7.50时，烟碱和总氮累积量达到最高值。

But after about a month to restore the root system, the leaves of nitrogen, phosphorus and potassium contents in treatment 5, 6, 7, 8, 2 gradually higher than the control. This is because the absorption of fertilizer during this period shown to promote on the elements, and with the passage of time the processing elements continue to be reduced to a leaf until the latter part of the growing season is also higher than the control.3.The pH value in rhizosphere soil of treatments poplar plantation were lower than that in non-rhizosphere soil, but the content of organic,available nitrogen, phosphorus, potassium, utility cuprum and utility zincum were all higher than those in non-rhizosphere soil.

但是经过大约一个月的根系恢复，处理5、处理6、处理7、处理8、处理2叶片中的N、P、K逐渐高于对照，这是因为施肥对元素的吸收在这一期间开始表现出了促进作用，并且随着时间的推移各处理中元素含量持续降低至落叶，直至后期的生长季节也高于对照。3、各处理的杨树林地根际土壤pH值均低于非根际土壤，而有机质、碱解氮、速效磷、速效钾、有效铜和有效锌的含量均高于非根际土壤，与其它处理相比，80cm两侧断根施肥处理的根际土和非根际土壤速效养分含量最高，差异达显著水平。

Feminism holds that women as the Other is the root of gender inequity in education. So it's required to find and value women's Voice. Meanwhile,Feminism recks that Motherhood should be the source of power to push forward the gender equity in education.

女性主义认为，女性在教育领域被&他者&化，是导致教育性别不平等的重要原因；而改变女性&他者&处境的路径，在于发现与肯定女性的&声音&；女性所拥有的最光辉的品质——&母性&，则是推进教育性别平等的力量源泉。

On the basis of experiment analyses we would got that, When arc met with chute, it was blocked and had a stagnation, this made hot gas flow incrase near the chute; After arc went into the chute, mental vapor from arc root would lower the dielectric strength near the chute, meanwhile, High value of arc voltage and the corase face of the chute made electric strength increase. These factors might give rise to local restriking near the chute, and made arc voltage drop suddenly.

总结实验结果并加以分析，本文提出了这样的观点：电弧进入栅片时，在入口处受阻后的停滞，会使该区域的热气流增加；进入栅片后，弧根蒸发的金属蒸汽、电弧热气流会降低栅片入口区域的介质强度；电弧被栅片分割后，电压急剧上升，再加上栅片表面的不均匀会使局部区域的电场强度显著增加，这些因素的综合作用会导致电弧在栅片入口附近发生局部重击穿，引起电弧电压电压跌落。

The potential of the dental crown to the middle point of dental root gradually reduced when the pH value of artificial saliva decreased.So adsorption of the cariogenic bacterium on the dental surface increased,incidence of the caries also possibly increasd.

本研究在人工唾液不同pH值时，通过对牙齿表面电位的测定，来观察牙齿表面电位随着人工唾液pH的变化，情况并探讨二者之间的关系，从而揭示酸的致龋机理，为龋病发病机理的研究提供一些实验数据。

The paper further analyzes and explores the ontological origins of "The world becomes an image" and "Man turns intoasubject", which is of determining meaning to the basic process of modern history, and points out, it is the western two-value logical nature and the abstract subjective principle of "objective thinking", while grasping "the being" as an entitative "object", that cancels the actual historical nature, excludes and overshadows the whole sensible richness of man and man"s sensible existent area which can not be objectified so that the freedom to use reason turns into rigidified rational external coercive power, resulting in the loss of meaning world as "the root of human life.

论文进而分析探讨了对于现代历史的基本进程具有决定性意义的&世界成为图像&和&人成为主体&的存在论根源，从而试图指出：正是西方&对象性思维&的二值逻辑本性和抽象主体性原则，在其将&存在&把握成实体性的&对象&时，也就取消了本真的历史性，排除和遮蔽了不能被对象化的人类感性的全部丰富性和人的感性存在领域；致使运用理性的自由转变成僵化之理性的外部强权统治，进而导致作为人类生命之&根&的意义世界的失落。
