不能说明的

From 24h to 96h, the removal rates of NH4 -N in every experimental group were all negative indicated that when being exposure to Hg2 , Egeria najas not only couldnt remove NH4 -N from water, but also would increase its concentration.

在24-96h的处理时间内，各实验组中细叶蜈蚣草对NH_4~-N的去除率基本为负数，说明在Hg~(2 )的作用下，细叶蜈蚣草不仅不能去处水中的NH_4~-N，相反还可能使水中的NH_4~-N增加。96h内水体NO_3~--N含量变化无明显的规律性，而细叶蜈蚣草对水体NO_3~--N的去除率变化规律比较一致，先上升后下降最后比较平稳。

The density is Granger of height and breast diameter, and the heightis Granger causality of the diameter too, but the diameter isn't the causality of the height when logging number equates 2. In the intercomparison of effects of the diameter, height and density each other, the effect of the height and density is far-reaching. The height and density should be paid more attention for maintaining its' effect on the diameter in forest management.

当滞后阶数为2时，密度是胸径、树高的Granger原因，树高是胸径的Granger原因，胸径不再是树高的Granger原因，说明胸径、树高、密度3个林分因子中，密度、树高的影响更深远，所以在森林培养时，一方面要更加注意林分密度，优化林木的营养空间，促进林木因子的全面生长，另一方面，也不能忽视对树高的培养，以维持树高对胸径的影响。

The researching result of this field is conflicting in these years. Some researchers consider it as apoptosis, while some necropsy results don\'t support the hypothesis. Our study is to investigate the protein expression and biochemistry changes under oxidative stress to determine if apoptosis happens.

多巴胺能神经元的死亡是凋亡还是坏死目前的研究结果不一，有许多的研究说明在氧化应激的条件下，细胞的死亡是凋亡，而部分尸检结果不支持凋亡的学说，本实验拟从蛋白表达及生化学方面观察氧化应激后细胞有无凋亡的发生。

" Sports is Caesarean ": A Neozoic network game, it is the sports style of domestic unmanned make inquires however, resemble such MMORPG really diversity, lie fallow to have both with athletics, but the success of a game cannot in the grandiose blue print that bureau be confined to conceives, the player's amount is a best specification, empire of very apparent sports was not accepted extensively.

体育帝国》：一款新生代的网络游戏，却是国内无人问津的体育风格，像这样的MMORPG的确多元化，休闲与竞技兼备，但一款游戏的成功不能局限于构思的宏伟蓝图中，玩家的数量是一个最好的说明，很显然体育帝国并没有被广泛接受。

The calculated results of present work show better agreement than those of the previous studies with the observed values. It can be found that the contributions to the EPR parameters from the ligand orbitals and spin-orbit coupling interactions cannot be neglected for the systems with significant covalency.

理论结果与实验符合得很好，且比前人的计算，尤其是g和A有明显的改进，说明对这类共价性较强的体系，配体轨道和旋轨耦合作用的贡献不能忽略。

B cyclamate is one of the many drugs already banned because of a possible link with cancer.

该题中，c项对上文的论点加以说明并提供了数据，表现了意思上的连贯，，项都不能表现这种意思上的连贯，正确的答案是。

Given the large number of high-quality games released in October, and the fact that consoles cost far more than individual games, it is unclear whether this signals a slowdown or a pre-Christmas shift from software to hardware purchases.

鉴于10月份有大量高质量的游戏上市，而且游戏设备远比游戏软件的价格要高，仍然不能清楚地说明这是预示着产业增长的减速还是由于圣诞前消费由软件向硬件的转移造成的。

The relations between the potential difference and the discharging time when the discharge current is a step function as well as a step function containing high frequency vibrations, the relations between one-dimensional and two-dimensional spark locations and potential difference based on the thin wall model and the thick wall model have been studied.

仿真研究了放电电流为阶跃函数以及含高频振荡时电位差与放电时间的关系；基于薄壁模型和厚壁模型，仿真研究了电极下表面一维放电点位置和二维放电点位置与电位差的关系；对于确定的电位差，仿真研究了放电点位置的分布情况，说明两点输入不能唯一地检测出放电点位置，从而引入四点输入检测的思想。

However, the nodule could be induced by germfree liquid that filtered from the rhizobia, cultural medium. It is proposed that the some soluble substances excreted by the cultured rhizobia, can stimulate the plant to form the root nodules. Nevertheless, the nodules formed by this way can't produce haemachrome. So the nodules show light green or white. And there are starch in them.

但根瘤的形成还可由培养根瘤菌的无菌滤液诱导形成，这充分说明根瘤菌生长过程中分泌的某种可溶性物质具有刺激植物形成根瘤的作用，但这种根瘤由于不能形成豆血红蛋白而呈淡绿色或白色，且根瘤中有大量淀粉积累。

Goldschmidt's title mirrors a theme of mine here: that evolution is an intermingling of material and information, and that genetic logic cannot be divorced from the laws of material form in which it dwells.

高兹史密特著作的标题反映了我在此要说明的主题：进化是物质与信息相互混合的过程，遗传逻辑不能与它栖身的物质形式的规律相互分离。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
