煤炭企业固定工的地位及现存问题的改进

本文对当前煤炭企业用工制度改革存在的问题、改进途径和各种形式用工的比例进行了分析,并指出为适应煤矿安全生产及机械化发展的需要,保持固定工的用工比例,克服“铁饭碗在手”等隋性意识,充分发挥他们的骨干作用是问题的关键。为此,本文提出了改变工资结构、劳动结构等相应的改革措施。

Milestone of the meridian science──970th anniversary of the Chinese Bronze Statue of Meridian

For more than a thousand years, Chinese people were aware of the transmitted sensations by the application of needles on the body surface. This practice is called acupuncture. Acupuncture had been recorded and transcribed in writings and in drawings, until finally the acupoints were inscribed onto a bronze statue. The bronze statue was called the Meridian Figure. Deeply embodied in the bronze statue is a tripartite confrontation-prism representation of the humans body. This concept was a great scientific achievement in ancient China. The author traces the history of Meridian science described in traditional Chinese medical terms. Then he explores a clear analogy of the meridian pathway (MP) phenomenon. In a model system, by using a simple segmental in vertebrate, certain parallels can be demonstrated with the meridian concept. For example, the author demonstrated a clear correlation rule among the central mechano-sensory channels, and characteristics of positional discrimination in individual nerve cells from different receptive field inputs. The evidence suggests that the MP phenomenon is an objective neurobiological response. To clarify the research objective in this paper, the author suggests that the MP is a bi-directional pathway along which a positional message signal is transmitted. This phenomenon is evoked by physical stimulation, transmitted linearly across the human body segments, and is perceived by the brain. The MP consists of low resistance paths, is connected by the liquid media contained in the apposite membranous structure. At the cellular level, the regulation functions of MP must pass through along this low resistance path. Two aspects of the modern Meridian research are the functional regulation and the mechanism of intercellular liquid modulation at the nanometer level.     

多媒体网络中的时延控制方法

时延和时延的抖动是多媒体网络中两个重要的参数,它们与网络的服务质量相关．提出了一种新的网络时延和时延抖动的控制方法——按时服务原则．该方法以虚拟时钟算法为基础,吸收了Ｊｉｔｅｒ－ＥＤＤ算法的优点,能够同时对时延和时延抖动进行控制．同以往的时延和时延抖动控制算法相比,其优点在于：无需为会话建立通信模型,只要是受漏桶（ＲＳ,Ｄ０）限制的会话,那么,该会话在按时服务器组成的网络中就存在一个最大时延Ｔ１,ＭＳ,ｍａｘ．
