In order to complete the investigation, impersonality feasible experiment solutions and devices are designed independently to systemically investigate on activation and transfer characteristic of soil heavy metal under acid rain effect. Primary results are shown as followings:1. PH measuring results of soil solution and eluviation solution show that the ability of experimental plot the acid buffer capacity of soil is stronger under the experiment condition,there is no obvious acidification in soil which after acid rain eluviation.The result has substantial differences with that gotten by most of investigationers in similar work before.

这一结果与以往类似研究中多数研究者得到的结论存在本质区别，原因可能在于此次试验的试验条件与以往研究的试验条件不同，其中最主要一点是在本次试验中使用的土壤样品的重量比以往试验均显著增大，而且使用的是土壤结构和组成等均未经破坏的原位土，从而使入渗酸雨与承受酸雨沉降的土壤之间的比例关系更接近自然酸雨沉降过程，以此为基础得到的试验结果应该更加客观、可靠。2、酸雨对盐基离子活化迁移产生的影响勿庸置疑，但是，在盐基离子活化迁移的过程中，并没有出现预想中的重金属元素活化迁移现象，表明土壤中的重金属元素并不如理论分析的那样对酸雨沉降反应敏感。

Note that these 32 subsets include T itself and the empty set, which contains no elements at all.

由于 中的每一个元素都属于T，所以我们说S是的一个子集由于T有五个元素因而T共有的一个子集。

For equivalent discernibility matrix has equivalent attribute reduction,the domain is partitioned into compatible and imcompatible elements in this paper.

利用等价差别矩阵具有相同属性约简的思想，将元素对象分割成相容对象与矛盾对象，通过对参与构造差别矩阵的行与列元素进行约简，减少了某些重复计算过程，提高了计算效率。

The change of fibers and hydroxy rubber in surface is determined by ESCA and SEM.

用电子能谱仪和扫描电镜对改性后的纤维和丁羟橡胶表面进行了测试，结果表明：C元素的含量明显下降，N和O元素的含量提高，纤维表面活性提高。

In addition, shattered wine bottle, leopard skin and sunglasses, burnt heaps of wood, violent behaviour in scenic spot, a horse toppled over and human body, and all the etceteras as well, in which matched along with a lot of elements in his painting - power, desire, violence and individual will, for example.

另外如破碎的酒瓶；豹皮和太阳镜；燃烧的火堆，风景中的暴力案件；倾倒的马和人体等等，这些情节和道具对应了作品中的诸多元素：权力、欲望、暴力、个人意志……这些元素呈现出不同的表达谱系，产生了多样的视觉刺激，在一个被颠覆的系统中呈现着各自的面貌。

The etiolation cause of new shoots was the deficiency of manganese and cuprum contents, and spraying microelements of manganese and cuprum on the new shoots can prevent and cure this disease.

新梢黄化叶中Mn、Cu元素含量显著低于茶树叶片正常范围的低限值，是导致其叶片黄化的原因；叶面喷施含Mn、Cu元素的肥料能有效防治幼龄茶树新梢的黄化。

In the end the important eutectoid elements and their intermediate compound with Ti were presented,respectively.

最后，对钛合金中重要的共析元素及它们与Ti元素形成的中间相分别进行论述，分析了这些中间相性质及析出特点。

The result is an explicit choice function : a function that takes the first box to the first element we chose, the second box to the second element we chose, and so on.

这个结果是一个明确的选择函数：这个函数映第一个集合到我们选择的第一个元素，映射第二个集合到我们选择的第二个元素，以此类推。

These results indicated that CaCl2 extractable fraction may not pay important role on metal phytoavailahility in the studied soils.

这些结果表明CaCl2提取态Zn、Cd对土壤中该元素的植物有效态可能不具重要贡献，而DTPA提取态金属和金属总量在一定程度上能作为评价土壤中元素植物有效性的标准。

Including reproduction, empty, to strike a tree height, the number of elements in the tree get root node, the father node, all the ancestors, the left son, right son, insert the left son, right son, to find an element, and the former , during and after, hierarchical traversal and related operations.

包括复制，清空，求取树高，树中元素的个数，得到根结点，父亲结点，所有祖先，左儿子，右儿子，插入左儿子，右儿子，查找某个元素，以及前、中、后、层次遍历和相关的操作。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
