After 72 h,168 h to observe amount and species of the attracted flies by the six materials in the three fields.Results There is amount difference of flies among three fields( P ≤0.01).There is also species difference of flies among six materials;In six materials,"canker fish+bean draff"(3∶2) attracted the most flies.The following is "canker fish+bean draff(3∶2)+ 0.1% TH6040".

结果在3种环境下，不仅6种诱蝇材料72h、168h诱捕的蝇数有很大的差别( H =10.80，χ2≤0.01； H =10.80，χ2≤0.01)，而且各诱蝇材料诱捕的蝇类种群构成亦有所不同；以腐鱼肚肠及豆渣(3∶2)诱蝇数量最多，其次为腐鱼肚肠及豆渣(3∶2)加0.1%灭幼脲；在同一环境，各诱蝇材料间差别亦很大。

Recently,one attribute re- duction definition based on the new information entropy is proposed by some researchers.

经深入研究，我们证明了该属性约简与基于HU差别矩阵的属性约简是等价的，从而给出了基于HU差别矩阵的属性约简的信息观解释。

The statistics wasanalyzed with statistics software SPSS11.0, the essential measurement data before andafter treatment was compared with matched-pairs t-test, and group comparison withindependent sampler t-test while enumeration data with chi-square criterion.

3结果 ①治疗前后部分生化指标：两组与治疗前比较有差别，P＜0.05，治疗组与对照组治疗后比较有差别，P＜0.05，说明结肠透析配合中药加活性碳保留灌肠治疗，可以使Scr，BUN降低，Hb有明显升高。

Calculating the equivalence class U/C and the discernibility matrices size are the two main factors which affect the efficiency of the attribute reduction algorithm based on discernibility matrices.

影响基于差别矩阵的属性约简算法效率的主要因素有计算U/C等价类和差别矩阵的大小。

To solve this problem,the equivalence relation of rough set theory is replaced by an asymmetrical similar relation,and from this relation,an asymmetrical similar matrix is defined,then a new heuristic algorithm with less space complexity that require core and knowledge reduction based on asymmetrical similar matrix is proposed,and an example is given to confirm the validity of the algorithm.

用非对称相似关系代替粗糙集理论中的等价关系，定义了非对称相似差别矩阵，提出了基于非对称相似差别矩阵的高效求核和知识约简算法。该算法无需改变初始不完备信息系统的结构，能直接处理缺省数据。实验结果表明，新算法所获得的决策规则简洁、高效，与缺省值无关。

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 airflow aroused by a butterfly flapping its wings over southern half-globe maybe lead to tornado over northern half-globe after several weeks' "combination", which is "butterfly effect" in chaos theory. It refers to a phenomenon depending on sensitivity of initial condition: the tittle difference in input will quickly amplify into overwhelming discrimination in fan-out.

一只蝴蝶在南半球扇动翅膀鼓起的气流经过几星期的"组合"，可能会导致北半球刮起龙卷风，这是混沌学理论中的"蝴蝶效应"，指对初始条件敏感性的一种依赖现象：输入端微小的差别会迅速放大到输出端压倒一切的差别。

Almost all of the foraminifera are present in the last glacial loess, but the distribution patterns of foraminifera show significant temporal changes.

冰期黄土中有孔虫化石的这种差别，说明同样是海平面下降，但不同时期海平面下降时可能具有巨大的差别。

There are so distinct social visions from Marx and Hilferding that Hilferding could make a foresighted perspective of finance.

作者认为Hilferding理论背后所预设的社会图像与Marx之间，存在著根本性的差别，此一差别使得Hilferding得以走出Marx的理论典范，提出一个前瞻性的金融观点。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
