张君劢中国近代化构想述论

在近代中国自由主义者当中 ,张君劢是少数几位直接关注中国近代化问题的人物之一。张的近代化构想涉及到民族国家的建立以及政治的、经济的、文化的建构等多方面。张始终把近代意识的养成即人的近代化视为国家近代化的基础和前提 ,但缺少对于社会根本改造的应有关注。张在主观上力求探寻一条既不同于英美式的又不同于苏联式的“第三条”近代化道路 ,实际上并未越出英美式的近代化模式。张所追求的仍然是一种英美式的资产阶级近代化。     

有奖储蓄中奖号码的计算机分析

本文根据K.Pearson X~2的检验法,对中国工商银行浙江省分行1981年1月～1987年12月所有的由摇奖机摇出的有奖储蓄的中奖号码,利用电子计算机进行了统计分析.运算结果肯定了中国工商银行浙江省分行目前的摇奖方法是可靠的.也就是说,每个月在全省的某一地、市、县轮流用不同的摇奖机、不同的号珠,由不同的操作人员摇出中奖号码的方法,是行得通的.同时也指出,广大储户完全没有必要去择号购奖券,甚至买好以后再去调换所谓“中意的奖券,因为相对于信度10%而言,我们肯定了假设H:0～9这十个号珠中的每一个被摇奖机摇出的概率是相等的.”     

动态分组在中小学英语教学中的应用

在教学中尝试“动态分组”的研究，背景主要基于以下三点：第一，实行了九年义务教育后，绝大多数的初一新生均是免试就近入学，随机编班，学生的知识、能力和个性等都差异很大；本校从小学三年级开始开设英语课。第二，近年来，由于客观方面的原因，学校班额很大，每班的学生均在60人以上甚至有86人一班的，无形之中教师的工作量增加了不少。第三，新一轮的课程改革引起新旧教学观念，新旧教学方法的必然碰撞，如何转变教学观念，教学方法如何创新，是我们必须面对的现实问题。     

关于Runge－－Lenz矢量的方向和大小的讨论

描述行星规律的R-L矢量在笔者所见的文献中只指出了它的方向但末证明，本文对其加以了证明；并在此基础上比较简略地计算了它的大小；进而讨论了它的物理意义。     

Investigation of iodine concentration in salt,water and soil along the coast of Zhejiang,China

Objective: We aim to describe the environment iodine concentration in salt, water and soil along Zhejiang Province coast in the China foreland. It will be helpful for us to judge whether this area is insufficient in iodine and universal iodized salt is necessary or not. Methods: We collected iodized salt samples, drinking water samples (tap water in the towns, and well water or spring water in the villages), water samples from different sources (ditches, lakes, rivers) and soil samples through random sampling in June, 2005. Salt, water and soil iodine was detected by arsenic-cerium redox method. Statistical analysis was expressed as mean±SEMby Windows SPSS 13.0. Results: (1) The iodine concentration in salt was 27.9±4.33 mg/kg (n=108). (2) Seventy-five water samples were collected. The water iodine value was 0.6～84.8 μg/L (mean of 11.66 μg/L). The watershed along the Qiantang River has significantly higher iodine content than the water in Lin'an in mountain area (P＜0.01). The iodine content and mean iodine content of tap water, well or spring water and natural water sources were 4.30±2.43 μg/L (n=34), 23.59±27.74 μg/L (n=19)and 12.72±10.72 μg/L (n=22) respectively. This indicated that among environmental water sources, the ditch iodine content was the highest with river water iodine being the lowest (P＜0.01). (3) Soil iodine value was 0.11～2.93 mg/kg (mean of 1.32 mg/kg).Though there was no statistical difference of soil iodine in different districts (P=0.131), soil iodine content correlated positively with water iodine content. Conclusion: Iodine concentration in salt accords with national policy of adding iodine in salt. Foreland has more iodine in water than mountain area. The data reflected that water and soil iodine in foreland area was not high, which suggests universal iodized salt should be necessary. Environment iodine has relatively close association with pollution.
