清入关前满洲民族联合过程与满洲对索伦部的政策

明清之际,满洲崛起于东北,以居住在辽宁东部的建州女真和吉林松花江沿岸至南部的海西女真为主体,联合东北其他少数民族形成满洲共同体。满洲的民族联合过程属于聚合过程,血缘、文化相近的民族或部落、部族汇聚为一个民族共同体。在满洲民族联合的过程中,索伦部一些人员加入满洲,成为新满洲,融入到满洲共同体中。对于满洲民族联合过程的发展做出了重要贡献。满洲对于仍居住在黑龙江北的索伦部,实行朝贡赏赐、联姻、编旗设佐政策,淡化其民族认同,加强其对满洲的政治认同。     

An integrated approach for water resources decision making under interactive and compound uncertainties

In recent years, the issue of water allocation among competing users has been of great concern for many countries due to increasing water demand from population growth and economic development. In water management systems, the inherent uncertainties and their potential interactions pose a significant challenge for water managers to identify optimal water-allocation schemes in a complex and uncertain environment. This paper thus proposes a methodology that incorporates optimization techniques and statistical experimental designs within a general framework to address the issues of uncertainty and risk as well as their correlations in a systematic manner. A water resources management problem is used to demonstrate the applicability of the proposed methodology. The results indicate that interval solutions can be generated for the objective function and decision variables, and a number of decision alternatives can be obtained under different policy scenarios. The solutions with different risk levels of constraint violation can help quantify the relationship between the economic objective and the system risk, which is meaningful for supporting risk management. The experimental data obtained from the Taguchi's orthogonal array design are useful for identifying the significant factors affecting the means of total net benefits. Then the findings from the mixed-level factorial experiment can help reveal the latent interactions between those significant factors at different levels and their effects on the modeling response.     

浅谈高校内部财务审计与工程审计的结合运用

高等学校内部审计从专业角度可分为财务审计和工程审计,审计实践表明工程审计并不是独立的,它与财务审计密切相关。高校内部审计中财务审计与工程审计的具体结合运用：事前审计,包括决策、概算等方面的把关工作;事中审计,包括资金、结算等方面的把关工作;事后审计,包括决算、效益等方面的把关工作。     

A simple method to obtain minimum aberration split-plot designs

ABSTRACT

Split-plot designs have been utilized in factorial experiments with some factors applied to larger units and others to smaller units. Such designs with low aberration are preferred when the experimental size and the number of factors considered in both whole plot and subplot are determined. The minimum aberration split-plot designs can be obtained using either computer algorithms or the exhausted search. In this article, we propose a simple, easy-to-operate approach by using two ordered sequences of columns from two orthogonal arrays in obtaining minimum aberration split-plot designs for experiments of sizes 16 and 32.     

高精度局域定向定位技术及其精度分析

针对目前自主局域定向定位的需求,文中提出了一种在近场模型下反向利用阵列信号处理相关理论实现阵列自身的高精度定向定位方法,仿真实验表明该方法可以有效实现阵列的高精度定向定位.进一步对该方法的定向定位精度进行了理论分析,通过仿真分析了阵列所处位置、信号源数目、阵列自身天线阵元数目以及信号源位置存在误差时对定向定位精度的影响,相关实验结论具有重要的工程应用指导意义.     

Taguchi methods: linear graphs of high resolution

An important reason behind the success of the Taguchi methodology in qual- ity assurance has been the use of statistical methods, presented in a way that is accessible to the nonexpert user. Among the tools used to simplify the sta- tistical design of experiments has been the linear graph, apparently introduced by Taguchi. However, he did not consider the resolution of the corresponding designs (the higher the resolution, the more accurate the conclusions). For example, it will be shown that half of the linear graphs given by Taguchi for the L₁₆(2¹⁵) orthogonal array correspond to designs of resolution III, when designs of resolution IV are available (with the same lines in the linear graphs but with different assignments to the columns of the orthogonal array). A nontraditional but very straightforward method is presented for obtaining the alias chains and the linear graphs corresponding to an orthogonal array. The procedure can be easily understood and employed by nonstatisticians to find an experimental design of the highest possible resolution. The design can be used to obtain products or processes that are robust to variation.

同构为美——中国古代美学关于美的心理本质的界说

中国古代美学资料说:“同声相应,同气相求。”“物固以类相召。”人性“爱同憎异”,“会己则嗟讽,异我则沮弃。”这些是异质同构为美思想的明确注脚;也是中国古代关于美的心理本质的固有思想。它与西方美学异质同构为美的思想异曲同工。究其成因,渊源于中国古代“天人合一”的文化模式。
