From our results we know that the average error of the Lagrange interpolation sequence and the Hermite interpolation sequence based on the Chebyshev nodes in the 1-fold integrated Wiener space equal weakly to the average error of their corresponding optimal approximation polynomial in the 1-fold integrated Wiener space,and as a kind of information-based operation,they have simple form and their recover functions are polynomials,in the 1-fold integrated wiener space,their average error equal weakly to the corresponding minimal information radius whose permissible information operators class is function values.
通过我们的结果可以知道,基于第一类Chebyshev多项式零点的Lagrange插值算子列和Hermite插值算子列在1-重积分Wiener空间下的平均误差弱等价于相应的最佳逼近多项式在1-重积分Wiener空间下的平均误差,并且作为形式简单且恢复函数为多项式的一种信息基算法,其在1-重积分Wiener空间下的平均误差弱等价于相应的以函数值计算为可允许信息算子的最小平均信息半径。

The conclusions are drawed as following:(1) both reinforcement learning moedel and BBAM can fit the information searching behavior on web in given context;(2) faced with a general restriction, which means a strong uncertainty, the decision making behavior of bounded rationality agent should involve completely rationally calculation and routinism without any conscious reflection on the situation;(3) agent's cognition evolution should be directed by consciousness, the convergence is affected by three factors: the initial belief system, the ...

The major findings of this research can be summarized as follow:1 The comparison of USPED model-estimated amounts of soil erosion based on four different scales of DEMs (1:250,000, 1:50,000, 1:10,000, and 1:5,000) indicates that 1:50,000 -scale DEM is almost as good as higher-resolution DEM data in providing needed topographic information for assessing soil erosion, whereas 1:250,000-scale DEM underestimates soil erosion mainly because rill erosion and sheet erosion are greatly underestimated.2 Since precipitation is the most important forcing factor for soil erosion, the accuracy of soil-erosion estimates understandably relies on the adequacy of spatially distributing point-observed precipitation data.
取得的主要成果如下:(1)基于四个尺度(1∶250,000,1∶50,000,1∶10,000,and 1∶5,000)的数字高程模型和USPED模型计算的土壤侵蚀结果对比表明,1∶50,000的数字高程模型与更高分辨率数字高程模型提供了几乎一样的用以估算土壤侵蚀所需的地形信息,而1∶250,000的数字高程模型,由于过低的估算了细沟侵蚀和片蚀,从而过低的估算了土壤侵蚀的总量。

Chapter four studies the chaotic responses in a system consisting of simple pendulum and harmonic oscillator under bounded noise excitation. Firstly, the Melnikov function of the two-degree-of-freedom system under Hamiltonian perturbation is derived. The essential condition of the autonomous system for the probable onset of chaos is obtained, the Poincare maps of the system under small Hamiltonian perturbation and the effect of increasing perturbation on the Poincare maps are studies. Then for the non-autonomous system under damping and harmonic or bounded noise excitation, the largest Lyapunov exponent and Poincare maps are calculated. From the analysis of the largest Lyapunov exponent, the critical criterion for the onset of chaos, and the conclusion that the threshold of bounded noise amplitude for the onset of chaos in the system increases as the intensity parameter of Wiener process increases are obtained. The result from the analysis of Poincare maps is in agreement with that obtained from the Largest Lyapunov exponent. The effect of varying damping coefficient and intensity parameter of Wiener process is also analyzed.
第四章研究了有界噪声激励下的两自由度单摆—谐振子系统的混沌运动,首先推导了该两自由度系统仅在Hamilton扰动下的Melnikov函数,得到该自治系统可能产生混沌的必要条件;研究了该系统在小的Hamilton扰动和增大摄动情形下的Poincare截面;然后对有阻尼、谐和或有界噪声激励下的非自治系统数值计算了其最大Lyapunov指数和Poincare截面;从Lyapunov指数分析得到了这个两自由度系统产生混沌运动的临界条件及产生混沌的临界激励幅值随Wiener过程强度参数值的增大而增大的结论,Poincare截面分析的结果亦符合Lyapunov指数分析的结论;研究了Wiener过程强度参数、阻尼系数变化对Poincare截面的影响。

The function mechanism among the minerals and floatation drugs had been studied with the way of IR and academic calculation, which pointed out that absorption of G-4 on the surface of phosphorite belonged to physical and chemical types, but the chemical one was in the highest flight. Absorption of amine collector named GE-609 on the surface of quartz belonged to electrostatic and physical type. Distilled water could hardly wash the GE-609 down from the surface of quartz. Leading component of S-721 was the concentrated compound of naphthol sulfonic acid and formaldehyde. The compound had a stronger affinity to the Mg~(2+) on surface of dolomite than the Ca2+ on surface of phosphorite, which is the essential reason in the separation of phosphorite and dolomite. The leading components of soluble glass in function were HSiO3 hydronium and F^SiC^ colloid granule.
通过红外光谱测定以及理论计算的方法研究了选矿药剂与矿物间的作用机理,研究表明:脂肪酸捕收剂G-4对胶磷矿的捕收作用是以化学吸附为主、化学吸附与物理吸附共同作用的结果;胺类阳离子捕收剂GE-609在石英表面的吸附属于静电物理吸附,但很难用水洗的方法使GE-609从石英表面脱附;S-721主要成分为萘酚磺酸与甲醛的缩合物,萘酚磺酸与甲醛的缩合物对白云石表面Mg~(2+)的吸附明显强于对胶磷矿表面Ca~(2+)的吸附,这是胶磷矿与白云石分离的根本原因;水玻璃溶液中对石英起抑制作用的主要组分是HSiO_3~-和H_2SiO_3胶粒,水玻璃除对石英起抑制作用外,对矿浆还具有一定的分散作用。

When growth rates are under discussion, it will pay you to be suspicious as to why the beginning and terminal years have been selected. If either year was aberrational, any calculation of growth will be distorted. In particular, a base year in which earnings were poor can produce a breathtaking, but meaningless, growth rate. In the table above, however, the base year of 1965 was abnormally good ; Berkshire earned more money in that year than it did in all but one of the previous ten.
一般在谈到成长率时,各位可能会怀疑基期与终期是如何选定的,因为如果选择不当,任何计算出来的结果都可能会被大大扭曲,尤其当基期的盈余过低时,很可能得出惊人但却不合理的成长率,不过在上表中,1965年的表现算是相当的不错,当年度的获利在那之前的十年中排名第二。
