The converse observation, of the absence of grazers in areas of high phytoplankton concentration, led Hardy to propose his principle of animal exclusion, which hypothesized that phytoplankton produced a repellent that excluded grazers from regions of high phytoplankton concentration.

高的浮游植物集中的区域的缺少吃草的动物相反的观察，努力地引导计画他的动物排除的原则，假定浮游植物生产了一个将吃草的动物排除在高的浮游植物集中的区域之外了的防水剂。

Based on the pattern of partial double-layer LICS, different analysis models of nonlinear, linear, rigid joint and pin joint were compared, linear property of double-layer region and nonlinear property of single-layer region was disclosed, and then a nonlinear-linear combine method was put forward with a definite object in view.

针对局部双层叉筒网壳的布局特点，本文对局部双层叉筒网壳进行了非线性、线性、刚接、铰接等多种分析方法的比较，揭示了双层区域的线性性质和单层区域的非线性性质，进而有的放矢地提出了&非线性-线性联合&这种适合局部双层网壳分析的合理、准确、高效的方法。

This method differentiates the flat region from edge region by the difference between the maximum mid-value and the minimum mid-value,which enhanced the ability of denoising in wavelet transform domain and effectively protect the details.

该方法利用最大和最小中值之差判断平坦区域和边缘区域，提高了小波域中去除噪声的能力，同时有效地保护了信号细节。

DSPR (Dynamic Scanlines Post-Reallocation) algorithm changes the boundary of block assigned to each Transputer after each operation, so that the total number of strips needed to travel around the network can be decreased, and then decrease the cost of communication.

DSPR后动态扫描线分配算法的出法点是运算后根据运算参数动态地改变分配给处理单元的显示区域的边界，这样就可以减少需要传送的不属于自己区域内的条码数量，进而减少运算后的通信开销。

A layer of strip steel was found abrasion-welded to the surface of the spalled fragment and a 0.06mm thin layer of untempered martensitic structure was observed on the surface of the roll just beneath the welded strip.

在剥落块的表面上粘结着带钢，在带钢下的轧辊表面上观察到一层厚度约0.06mm未经回火的马氏体组织，此层下面还有一个具有低硬度的回火马氏体区域，晶间显微裂纹就从此两区域之间发生，然后垂直地向里向外扩展。

If the government can really have the courage to carry out proper planning of the right to rezone farmland within a certain district for construction use, and to distribute the profit from the rezoning equally among all of the owners of farmland within the district so that they can achieve the early realization of their dream, then many farmers will give up their stubborn hold on their farmland and transfer it to more efficient users.

如果政府真有魄力将一个区域内农地变为建地的权利做好规画，并将变更利益平均分配给区域内目前全部农地的拥有者，让他们的梦想提前兑现，则许多农民会减退对农地的执著，转让给更有效率的使用者。

Based on the above-mentioned parameter, according to the relationship between robust estimation and nonlinear diffusion, the Turkey loss function is introduced as the diffusion function in SAR image decomposition because of its better performance, and the contour of an image is extracted by the Turkey diffusion function with the proposed diffusion parameter mentioned above. The experiment results indicate that the Turkey loss function based diffusion process can strengthen the conspicuous contour. Additionally, a Raita\'s criterion-based method, solving the automatic diffusion threshold, is proposed to automatically set the threshold in diffusion decomposition.

针对基于梯度参数和局域方差系数的扩散在对SAR图像进行分解时存在的缺陷，提出了一种局域方差系数与窗口幅度均值积的扩散系数，该系数能够更有效地实现潜在目标区域和背景区域的区分；在此基础上，根据鲁棒估计与非线性扩散的联系，引入扩散效果更好的Turkey损失函数作为图像分解中的扩散函数，并结合局域方差系数与窗口幅度均值积的扩散参数来提取图像的轮廓，结果表明：基于Turkey损失函数的扩散过程对特征突出的边缘所起的&强化作用&更加明显；此外，针对扩散分解中的阈值确定问题，提出了一种基于拉依达准则的扩散阈值自动求解方法，实现了扩散阈值的自动求解。

区域经济一体化过程中，预防职务犯罪工作面临着新的机遇，也面临着严峻的考验，如何把预防职务犯罪工作延伸到区域经济一体化进程中，更好地服从、服务于党的工作大局，是我们当前和今后一个时期务必做好的一项崭新工作。

According to ecological observation and analysis of Ericerus pela living in Emei, Zhaotong and Kunming, the environments of which encourage rates of high excreted waxes are not suitable growth areas for Ericerus pela. The main ecological characteristics for suitable growth areas of Ericerus pela are described as follows: annual average temperature 11-16℃, light 1900-2500 h/a, rain fall 800-1200 mm and annual relative humidity 65%-75%.

根据在峨嵋、昭通、昆明等地对白蜡虫的生态适应性观察和分析，白蜡虫泌蜡高的环境不是白蜡虫适生区域，白蜡虫适生区域主要生态指标为：年均温11～16℃，降雨量800～1200mm/年，年相对湿度65%～75%，年光照时数为1900～

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
