Planning for the 1950 Censuses of Population and Agriculture

The change from the z of “Student's” 1908 paper to the t of present day statistical theory and practice is traced and documented. It is shown that the change was brought about by the extension of “Student's” approach, by R.A. Fisher, to a broader class of problems, in response to a direct appeal from “Student” for a solution to one of these problems.     

Methods for calculating stationary distribution in linear models of time series

The article deals with methods for computing the stationary marginal distribution in linear models of time series. Two approaches are described. First, an algorithm based on approximation of solution of the corresponding integral equation is briefly reviewed. Then, we study the limit behaviour of the partial sums c ₁ η₁+c ₂ η₂+···+c _n η _n where η _i are i.i.d. random variables and c _i real constants. We generalize procedure of Haiman (1998) [Haiman, G., 1998, Upper and lower bounds for the tail of the invariant distribution of some AR(1) processes. Asymptotic Methods in Probability and Statistics, 45, 723–730.] to an arbitrary causal linear process and relax the assumptions of his result significantly. This is achieved by investigating the properties of convolution of densities.     

弱电解质溶液中c／ka^o比值对解离度误差的影响

介绍了溶液中弱电解质平衡体系的pH计算是《无机化学》课程中的重要基础理论知识。为简化计算经常需要引入近似条件，这样必然造成误差。通过理论计算解释了不同c／ka^o值与解离度误差的关系和不同解离度误差对应的c／ka^o值，对学生正确理解相关内容大有助益，是教材内容的必要补充。

赛珍珠:一位文化边缘人

历时地看,作为美国第一位获得诺贝尔文学奖的女作家,赛珍珠显然没有受到学术界应有的重视。站在全球化语境下去认识赛珍珠,通过引入"文化边缘人"的概念去解读赛珍珠,我们可以找到赛珍珠及其作品被排斥在经典之外的原因。作为文化边缘人,赛珍珠站在了时代的前列,这也是在当今多元文化的语境下她被学术界"重新发现"的主要原因。从这个视角切入,我们可以更好地认识赛珍珠在当代世界文坛的文学地位。     

新世纪新成果--评《赛珍珠纪念文集》

<赛珍珠纪念文集>收录了2002年中国镇江赛珍珠学术研讨会的论文及文章,它的出版,标志着新世纪中国的赛珍珠研究正向纵深推进.该文集主要具有三方面的价值,即资料性、学术性和方法论意义.     

Projective (2n,n,λ,1)-designs

A projective (2n,n,λ,1)-design is a set $\text{D}$ of n element subsets (called blocks) of a 2n-element set V having the properties that each element of V is a member of λ blocks and every two blocks have a non-empty intersection. This paper establishes existence and non-existence results for various projective (2n,n,λ,1)-designs and their subdesigns.     

“S+V+R+O”双核谓词格框架研究

在“S +V +R +O”句式中 ,由于述语中心动词V价的不同、宾语的不同 ,补语R语义指向的不同 ,主语S、述语V、补语R、宾语O构成一个复杂的语义网络。弄清楚其中的语义网络 ,就可以着手建立“S +V +R +O”双核谓词格框架了。建立双核谓词格框架 ,可以促进对句子的理解 ,促进现代汉语格系统的建立     

从《父子之间》看早期生活对奈保尔文学创作的影响

《父子之间:家庭书信集》为我们研究奈保尔提供了最为真实可信的历史材料。通过分析这部家庭书信集,揭示出作家少年时代特立尼达生活的"文化悬挂",青年时代留学英伦经历的"文化祛根",以及父亲在文学上对儿子的影响;所有这些对于奈保尔精神气质和文学理念的初步形成,有着不可低估的作用。更重要的是,作家后来的"文化无根"状态,与这一时期的生活有密切关系。对这部书信集的研究,是全面了解奈保尔的必要起点。
