建构主义教学观与国际商务信函教学
Teaching of International Business Correspondence under the View of Cnonstructivist Learning
 [PDF]


Modern Linguistics (ML) , 2014, DOI: 10.12677/ML.2014.23016
Abstract:
本文基于建构主义理论中的教学观,在总结商务信函教学特点的基础上,分析了商务信函教学的现状及其存在的问题,最后,本文提出商务信函教学要以调动学生的主观能动性为核心,并为教改的内容提出四个方面的建议。
The paper summarizes the characteristics of the course of international business correspondence, and then, it analyzes the situation and the problems of such teaching. In addition, based on the Constructivist View of Learning, it points out that the core of the teaching is to stimulate the drive of the students in the process of teaching. At the end of the paper, four suggestions are put forward concerning the reform of the teaching.

Abstract: 通过对三峡库区万州区几十处滑坡勘察、设计和施工资料的综合分析,进行了滑带土抗剪强度参数(粘聚力c 和内摩擦角?)的统计分析,利用χ2 检验法进行拟合,从而得出了c 和? 值的概率密度函数以及它们的概率分布形式:c 值服从对数正态分布,而? 值服从正态分布;以此为先验函数,利用Bayes 方法对万州区关塘口滑坡滑带土的小样本参数c 和? 值进行优化。计算结果表明,优化后方差和变异系数分别下降了37.6% 和32%,因而可以提高滑坡防治工程的可靠性,从而达到滑坡优化设计的目的。

Abstract: The paper presented a multi-parameter optimized joint source channel coding method (MPO-JSCC), combined with JPEG2000 and Turbo codes for image transmission. On the basis of conventional layered-rate allocation mechanism, also chose the interleave length and iterative decoding times dynamically, according to the importance of that quality scalable bitstream for image recovery. Introduced the error resilient tools JPEG2000 provided to improve the image reconstruction ratio at the receiving end. Compared to the approaches reported in the literature, the MPO-JSCC method gives better compression efficiency while having higher coding gain, and reduces the transmission power budget.
内核民主的外化——论户籍制度的改革
The Externalization of Kernel Democracy—On Reform of the Household Register System

Abstract:
从广义的角度来说,一个国家的政治制度从内到外可以分为三层。我国户籍制度的改革,即属于我国外层政治运作制度的改革。作为外层政治运作体制之一,户籍制度的改革是外层政治民主的需求,也是内层政治民主外化的需求,它有利于实现马克思主义对真正的民主的设想,有利于实现共产主义,进一步促进外层政治运作制度的民主。我国户籍制度改革应遵循科学发展观,尽快提供更为完善的法律支持、政策支持,建立相对公平、公开、公正的平衡机制,在教育、医疗、住房等领域向中小城市倾斜,始终坚持社会主义和人民民主专政。
From a general perspective, the political system of a country can be divided into three layers from inside to outside. The reform of the household register system in China belongs to the reform of the outer layer political operation system in our country. As one of the outer layer political operation systems, the reform of the household register system is not only the demands of the outer layer political democracy, but also the demands of the externalization of the inner political democracy. It’s conducive to achieving the Marxist vision of true democracy and the communism, further promoting the democracy of the outer layer political operation system. The reform of the household register system should follow the scientific concept of development, provide more comprehensive legal support and policy support as quickly as possible, and establish a relatively fair, open and fair balance mechanism. And it also should tilt to small cities in the areas of education, health care, housing, etc and always adhere to the socialism and people's democratic dictatorship.

自由基在抗癌中的作用

生物化学与生物物理进展 , 1984,
Abstract: 关于自由基与肿瘤的关系,早期的研究,注意力集中于自由基在致癌方面的作用。近年来,有些研究发现,自由基也有抗癌作用。这方面的资料虽然不多,但值得注意。本文将近几年这方面的研究发展向读者做一介绍。一、自由基在肿瘤放射治疗中的作用放射线对机体的作用,通常是通过两种方式:(1)直接作用,即射线直接作用于生物分子的损伤效应;(2)间接作用,即射线作用于体内

云南新平县双沟蛇绿岩U—Pb年代学初步研究

岩石学报 , 1998,
Abstract: 对滇西哀牢山双沟蛇绿岩进行了U-Pb年代学研究。龙塘辉长岩锆石U-Pb下交点年龄为362±41Ma;双沟斜长花岗岩给出U-Pb年龄328±16Ma。这一结果表明滇西地区存在海西期蛇绿岩套,为解决古特提斯洋形成时代问题提供了新的年代学依据。
