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。

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.

Analysis for testability is widely used in DFT and test pattern generation, but most testability analysis algorithms have the shortcoming of either inaccuracy or being too complicated. A new method to calculate the signal probabilities of the nodes in IC is pre-sented in Chapter 7 of this dissertation. The signal probabilities by our method is more exact than by the previous ones. A symbol of the signal probability at the fan-out node is created and is propagated to the RFON (Reconvergent Fan-out Nodes). At the RFON, the expression containing the symbol is simplified using the rule which corresponds to the law of identity in Boolean algebra. After the expression is simplified, the symbol is substituted with its numeric value. Theoretical analysis shows that this method is concise and has a low computing complexity.

可测试性分析在可测试性设计和测试生成中都有着广泛的应用，然而大部分的可测性分析方法都存在不精确或者过于复杂的毛病，在第七章中作者提出了一种新的计算IC电路节点的信号概率值的符号算法，该算法得出的信号概率值比用以往的算法法得出的要更准确，也更简洁，针对电路中的扇出节点重汇聚现象，我们在每一个扇出节点定义了一个信号概率的符号，在以后的计算中一直使用该符号参与计算，直到该符号传播至重汇聚处，利用一定的规则把含符号的表达式化简，再将符号的真实值代入，在计算符号概率的过程中定义了一个和布尔代数中的同一律相对应的运算规则，通过该运算规则，使得信号概率的结果更加准确，符号算法具有简洁方便，计算复杂度小的特点 4。

Finally, a contrast is made between the results of the research and acquisition of the interlanguage rhetorical questions.

Allowed the date that" year" indulge in atrocities on the whole, the common people treat this terrible night as to close to come then very, call" year end", and figured out a the whole set to celebrate New Year's Eve the way of the pass:Each time to this evening, each per families work well the supper in advance, turn off the clean cooking stove, then chase a fastening with all stockade of chicken, the house hospital in front and back the doors all seal, hiding to eat" New Year's Eve dinner" in the house, because of this dinner have fierce 吉 don't 卜 of meaning, so buy very flourishing, in addition to wanting that the whole family the old and the young rounds together to have a meal to mean in peace and harmony and reunitedly, return the beard at have a meal to provide the worship of ancestors before and first first, the spirit of the imprecation ancestry protect, spending this night safe and sound, after eating the supper, who all dare not the sleeping, pushing to sit together to talk away to encourage.

到了宋代，人们便开始在桃木板上写对联，一则不失桃木镇邪的意义，二则表达自己美好心愿，三则装饰门户，以求美观。又在象征喜气吉祥的红纸上写对联，新春之际贴在门窗两边，用以表达人们祈求来年福运的美好心愿。为了祈求一家的福寿康宁，一些地方的人们还保留着贴门神的习惯。据说，大门上贴上两位门神，一切妖魔鬼怪都会望而生畏。在民间，门神是正气和武力的象征，古人认为，相貌出奇的人往往具有神奇的禀性和不凡的本领。他们心地正直善良，捉鬼擒魔是他们的天性和责任，人们所仰慕的捉鬼天师钟馗，即是此种奇形怪相。所以民间的门神永远都怒目圆睁，相貌狰狞，手里拿着各种传统的武器，随时准备同敢于上门来的鬼魅战斗。由于我国民居的大门，通常都是两扇对开，所以门神总是成双成对。唐朝以后，除了以往的神荼、郁垒二将以外，人们又把秦叔宝和尉迟恭两位唐代武将当作门神。相传，唐太宗生病，听见门外鬼魅呼号，彻夜不得安宁。于是他让这两位将军手持武器立于门旁镇守，第二天夜里就再也没有鬼魅搔扰了。

On the basement of conventional direct fan-beam reconstruction, this paper gives a newly improved algorithm-"fast filtering-backprojection". This method utilizes the symmetrical circle geometry to sample projection data, and reconstructs image on the Polarcoordinate firstly, then translates this reconstructed image onto the cartesian coordinate system with two interpolating operations so that the computer can show the result image on the VGA screen. This algorithm rebates the calculating backprojection greatly, and shortens a few times of reconstructing time than same kinds of means. With the size of image enlarging, the reconstructing time abates with 2 exponent times. In addition, according to the idea of parallel-beam, we rearrange the fan-beams and reconstruct image using parallel-beam method fastly. The rearranging constraint condition is given here.

本文首先在传统的扇束直接重建方法的基础上，提出了一个改进的快速滤波反投影重建算法，它利用旋转采集投影数据的圆周对称的几何关系，先在极坐标系统内进行图象的重建，然后通过两次内插运算再将图象转换到计算机显示方式下的笛卡尔坐标系中去，该方法将以往的直接重建方法中的反投影时所需的运算大大降低，并将重建时间比同类方法缩短了几倍，而且随着重建图象的尺寸的增大，重建时间以2的指数次方倍相对缩短，并获得了较好质量的重建图象；另外，又根据平行束投影重建图象的思想，对扇形射束进行了重排，然后利用平行束重建图象的方法进行扇束的重建，并推导了&扇束重排重建图象&方法的约束条件。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
