论儒家“道之以德”教育方法的现实意义

儒家认为道德教育首先是对教育者的要求，在道德问题面前，教育者必须首先反思自己，而不是只对受教育者的指责。这种在问题面前要求教育者首先有道德“道之以德”的方法是一种真正具有“德性”的教育方法，对于改善当前因方法造成的德育困境具有重要的现实意义。     

Modelling non-normal first-order autoregressive time series

We shall first review some non-normal stationary first-order autoregressive models. The models are constructed with a given marginal distribution (logistic, hyperbolic secant, exponential, Laplace, or gamma) and the requirement that the bivariate joint distribution of the generated process must be sufficiently simple so that the parameter estimation and forecasting problems of the models can be addressed. A model-building approach that consists of model identification, estimation, diagnostic checking, and forecasting is then discussed for this class of models.

A Structured Methodology for Local Network Design Engineering

This paper presents a structured methodology for local network design engineering (SMLNDE). A complex and fuzzy project for local network design can be decomposed into a set of simple and particular activities using the SMLNDE. The SMLNDE allows rigorous requirements definition and permits the exhaustive consideration of the large number of factors influencing local network design engineering. The complete and clear design documentations and an optimal design can also be provided by the methodology. The SMLNDE has been implemented using the structured analysis and design technique. The study shows that the SMLNDE is an effective design methodology for the large and complex local networks.     

The generation of random,binary unordered trees

Several techniques are given for the uniform generation of trees for use in Monte Carlo studies of clustering and tree representations. First, general strategies are reviewed for random selection from a set of combinatorial objects with special emphasis on two that use random mapping operations. Theorems are given on how the number of such objects in the set (e.g., whether the number is prime) affects which strategies can be used. Based on these results, methods are presented for the random generation of six types of binary unordered trees. Three types of labeling and both rooted and unrooted forms are considered. Presentation of each method includes the theory of the method, the generation algorithm, an analysis of its computational complexity and comments on the distribution of trees over which it samples. Formal proofs and detailed algorithms are in appendices.

响应曲面法优化聚丙烯酰胺的反相乳液聚合

通过二次回归正交旋转组合实验设计,以单体质量分数、引发剂质量分数和反应温度为考察因素,用响应曲面法分析了这3个因素对产物聚丙烯酰胺特性粘数的影响.通过采用DPS数据处理软件,建立了聚合工艺的预测模型,预测最佳聚合工艺条件为:ω(单体)=40.0%,ω(引发剂)=0.2%,反应温度41.6℃,预测特性粘数为14.00 dL·g-1,验证实验所得的特性粘数为12.25 dL·g-1.两者结果相近,说明响应曲面法优化得到的聚丙烯酰胺反相乳液聚合模型是适用可行的.     

高效Ni 2+ 吸附菌株分离鉴定及特性研究

采用浓度梯度筛选的方法,从活性污泥中筛选到一株能耐受并吸附Ni 2+的菌株,命名为Ni-1.采用单因素法对菌株Ni-1的最适培养条件进行了考察,确定培养条件为t=30℃,pH=7.0,1.0%的NaCl.考察了菌株Ni-1对Cu2+和Ni 2+的吸附性能,并用表面响应法优化了吸附条件.菌株Ni-1吸附Cu2+的最优条件为Cu2+100mg/L、投加菌量(湿重)0.85g、溶液pH=6.0,在此条件下对Cu2+的最大吸附率为87.13%.菌株Ni-1吸附Ni 2+的最优条件为Ni 2+50mg/L、投加菌量(湿重)0.85g、溶液pH=6.0,在此条件下对Ni 2+的最大吸附率为84.32%.实验结果表明该细菌对较低浓度的Cu2+和Ni 2+有较好的吸附性能.
