On the other side are some ethologists who seem to be more generous-minded, who see no compelling reasons to doubt that animals in general are quite capable of real thinking and do quite a lot of it -- thinking that isn't as dense as human thinking, that is sparser because of the lack of language and the resultant lack of metaphors to help the thought along, but thinking nonetheless.

在另一方面是些显然有更宽广的胸襟的比较动物学者，他们明白没有强迫的理由怀疑总的来说动物是相当有能力真正地思考并且做许多事情－－虽然思考不是像人类思考那样密集，而且由于语言的缺乏和因此缺乏隐喻来帮助思考因而是薄弱的，但不管怎样思考着。

Firstly, Wavelet-Galerkin algorithm for solving the first kind of singular integral equation with the Hilbert kernel is proposed, we use the characteristic of periodic wavelet on L~2([0,1]) and Hilbert kernel to solve and make stiff matrix lower dimensions and become sparser through thresholding,thus the cost of computation is reduced. Because of the singularity of Hilbert kernel we use Tikhonov regularization method to solve the system of stiff equation. At last the convergence and numerical result of approximate solution are given. Secondly, an approach of regularization based on Fourier is presented for sideways heat equation; we give the theory proof and error estimate.

首先，提出了含Hilbert核的第一类奇异积分方程的小波伽辽金(Wavelet-Galerkin)数值算法，该算法中利用了L~2([0，1])上的周期小波和Hilbert核的特点进行处理，使得刚性矩阵维数降低并且通过阈值使得它更加稀疏，减少了计算量；由于Hilbert核的奇异性，通过Tikhonov正则化方法求解所得到的刚性方程组，给出了收敛性和数值结果；其次，对标准的一维逆热传导方程给出了一种基于Fourier正则化方法，给出了理论证明及其误差估计，解决了文献中算法与理论误差估计的不相匹配的现象，该正则化方法不仅保留了测量数据的部分高频成份，且与文献中的算法具有同样的计算量和误差估计。

The superficial microvascular networks were sparser, while the subpleural microvascular networks were denser. The superficial blood vessels and the interlobular blood vessels were mutual transitional, and the anastomosing between the superficial blood vessels with the subpleural vessels. According to the branching sequence of the subpleural arteriole, it could be divided into the arteriole, terminal arteriole, precapillary arteriole and capillary in turn. The subpleural capillary networks were mainly web-like, while small holes were also found on the cast. The honeycomb vascular networks were various in size and form at a low magnification. The outline of alveolus, alveolar sac, alveolar duct and respiratory bronchiole and terminal bronchiole, made of microvascular networks, could be found in the cut surface.

内蒙古草原区两个不同热量型研究站点植被本底调查和显域地境群落学水平的比较研究表明：随纬度增加和气温降低，植物科、属、种的数目，生活型组成，群落类型和生境类型的多样性均趋于减少，而C3/C4光合功能群比值和群落的物种丰富度，株丛密度，物种多样性，群落均匀度，叶面积指数，叶面积持续时间和群落干物质生产能力均趋于增加，群落生产力动态曲线从随天然降水的季节分布不均而剧烈波动趋向于随气温逐渐升高和热量逐步积累而稳定增长，显示出两站点植物群落从较为旺盛的群体净同化作用、较为稀疏高大的群体结构和少数物种占有较多群落资源的生产力格局向较高的群体密度、优良的多叶性能和多物种资源共享的群落生产力格局转变，反映出在内蒙古草原区不同的自然历史环境背景和不同的温度条件及其水热组合状况影响下，两个不同热量型草原站点植被性质的分异特征和显域地境群落生长模式的较大差别。

The results showed that:(1) some governing points, which were measured by submeter precision GPS, were utilized to correct the 1 m precision remote sensing image and it could satisfy the desired precision of geometrical correction, therefore, this method could be used as geometrical correction in the region where was short of the big scale relief map;(2) the density of the original data was the main factor to affect precision of the volume, and the precision of the calculated volume of earthwork could be improved to more than 90% when using the test points and feature points; the sparser the data density were, more significant could be improved; On the base that elevation of test points were measured by the submeter precision GPS, the error of the volume, which was produced by vectoring relief map to obtain DEM, could be calculated, and the calculation precision of the earthwork could be improved markedly.
