光纤传感器在海洋环境监测中的应用

海洋是个特殊的环境,为许多光纤传感器提供了一个极好的应用领域。对于海洋这个特殊的“敌对”环境,光纤传感器将面临许多挑战。 本文着重介绍应用于海水温度、浊度、盐份浓度、浮游生物和溶解物光吸收量以及环境湿度等海洋环境参数监测的光纤传感器的原理、结构和特性,展望光纤传感器在海洋环境监测方面的美好前景。     

How to Control Robots Interacting with Dynamic Environment

The goal of this paper is to shed light on the control problem of constrained robot motion from the aspect of the dynamical nature of the environment with which the robot is in contact. Therefore, the criticism of traditional hybrid control which allows position/force feedback loops to split into independent control with respect to position and force, is not the main point we want to make. Reference to the papers written by the founders of hybrid control and their numerous followers served only to better understand the reason and motivation for suggesting a different approach to control of robots interacting with environment.The paper has a predominantly review character, based on recently published work. It also contains some new, unpublished results in the framework of the unified approach to the position/force control of robots, proposed by the present author and his co-workers. By pointing to the possibility of introducing an environment dynamics in the contact tasks of the machining type, the author emphasizes that the proposed dynamically interactive control can be applied to a completely different class of tasks, in which a contact is made between the system (constructions or structure) and very specific kinds of dynamic environments.

乙二醇合成工艺的研究进展

对国内外乙二醇合成的传统工艺:直接水合法、催化水合法和碳酸乙烯酯法进行了介绍;对乙二醇合成的新工艺,包括乙二醇和碳酸二甲酯联产法和C1化学法的工艺流程和发展前景进行了综述,其中,C1化学法主要分为乙烯合成法、合成气合成法和甲醛、甲醇合成法。作为合成气合成法之一的合成气偶联合成法,具有工艺要求不高、反应条件温和等优点,是目前最有希望大规模工业化生产乙二醇的工艺路线。     

Sky blue,but what blue? A new evaluation of the colors of the sky for artists and designers

This study describes a process of relating the perceptual analysis of the colors of the terrestrial atmosphere to currently available pigments used in artists' painting systems. This process sought to discover how the colors of the sky could be defined and simulated by these pigments. The author also describes how confusion over the bewildering choice of suitable pigments on offer in the market place can be clarified. © 2006 Wiley Periodicals, Inc.

Patient thermal comfort requirement for hospital environments in Taiwan

This study examines the comfort criteria of ASHRAE Standard 55-2004 for their applicability in hospital environments. Through an extensive field survey conducted in a university hospital in Taiwan, 927 sets of data have been collected. Above half of the measured samples failed to meet the specifications of Standard 55 comfort zone due to improper humidity control. Acceptability votes by patients exceeded the Standard's 80% criterion, regardless of whether the physical conditions were in or out of the comfort zone. Thermal neutrality, preference and comfort range are compared with other studies conducted in office environments and Standard 55 criteria. Results of chi-square tests revealed that patients’ physical strength significantly effected their thermal requirements. The net effect of health yields a marked difference in thermal neutrality and preference, and also in the comfortable temperature range.

环境资源负外部性与产权理论的新进展

环境资源共有产权的特性使得社会成员只能通过自身感知和理解确定对环境资源的产权边界，并且产权的实施是非排他的，所以与环境资源有关的负外部性较其他具有直接因果关系的外部性特殊。在治理这类负外部性的过程中，产权理论也有了新的发展。本文从分析环境资源产权的特殊性入手，对于产权弱化、产权分割、创建新产权和自愿合作基础上认知产权调整等负外部性内部化理论进行了分析。
