本文以理性官僚制为分析对象，阐述了理性官僚制产生的前提条件、存在方式及其主要特征，揭示了理性官僚制的固有悖论，并提出了在行政环境飞速变化的现代社会，对理性官僚制进行救治的相应措施。     

产品的信息不对称特征对企业广告策略的影响

产品的信息不对称广泛存在于消费者的购买过程中,存在于消费者和企业两个主体之间。文章在说明信息不对称含义及其特征在不同行业表现的基础上,提出了产品的信息不对称特征对企业广告策略的具体影响,这对企业广告策略的制定具有重要意义。     

整系数多项式不可约判别法

多项式在有理数域上可约的问题可以归结到整系数多项式能否分解成次数较低的整系数多项式的乘积的问题．Kronecker和Eisenstein分别给出了整系数多项式在有理数域上是否可约的判别方法，本文给出了另外一个判别整系数多项式不可约的判别法，对Eisenstein判别法予以补充．     

On the Western Conception of Natural Law

Natural law is an important concept of the Western political culture. The author makes a simple investigation into the various definitions of natural law, based on which he comes to the conclusion that natural law is a key concept of Western political culture; that it is a moral norm of politics as well as a product of rational thinking; and that its meaning has varied over time.

丁广义割圆序列的线性复杂度

Minimal polynomials and linear complexity of binary Ding generalized cyclotomic sequences of order 2 with the two-prime residue ring Zpq are obtained by Bai in 2005. In this paper, we obtain linear complexity and minimal polynomials of all Ding generalized cyclotomic sequences. Our result shows that linear complexity of these sequences takes on the values pq and pq-1 on our necessary and sufficient condition with probability 1/4 and the lower bound （pq - 1）/2 with probability 1/8. This shows that most of these sequences are good. We also obtained that linear complexity and minimal polynomials of these sequences are independent of their orders. This makes it no more difficult in choosing proper p and q.     

第二类Fredholm积分方程的快速数值解法

对于具有弱奇性核函数的第二类Fredholm积分方程，将核函数所定义的区域分成大小不同的正方形子区域，利用分层插值多项式逼近核函数，由此得到近似矩阵B实现了积分方程的快速数值解法。在最后，对如何提高方案的数值稳定性作简要讨论并给出要讨论并给出数值结果。
