Technical Notes ：STUDIES ON THE VALUE OF SECONDARY MARKET TO THE SUPPLY CHAIN

This paper investigates the impact of a secondary market, where retailers can buy and sell excessinventories, on the supply chain. We develop a two-period model with a single manufacturer and tworetailers. At the beginning of the first period the retailers order and receive products from themanufacturer, but at the beginning of the second period, they can trade surplus products betweenthemselves in the secondary market. We investigate the impact of the correlated dependence ofretailers' demand on both the quantity effect and the allocation effect under the secondary market.Lastly,we study potential strategies for the manufacturer to increase sales with the existence of thesecondary market.

FROM MANUFACTURING SCHEDULING TO SUPPLY CHAIN COORDINATION：THE CONTROL OF COMPLEXITY AND UNCERTAINTY

With time-based competition and rapid technology advancements, effective manufacturingscheduling and supply chain coordination are critical to quickly respond to changing marketconditions. These problems, however, are difficult in view of inherent complexity and variousuncertainties involved. Based on a series of results by the authors, decomposition and coordination byusing Lagrangian relaxation is identified in this paper as an effective way to control complexity anduncertainty.A manufacturing scheduling problem is first formulated within the job shop context withuncertain order arrivals, processing times, due dates, and part priorities as a separable optimizationproblem. A solution methodology that combines Lagrangian relaxation, stochastic dynamicprogramming, and heuristics is developed. Method improvements to effectively solve large problemsare also highlighted. To extend manufacturing scheduling within a factory to coordinate autonomicmembers across chains of suppliers, a decentralized supply chai     

Radar Imaging Based on Iterative Algorithms

It has long been realized that the problem of radar imaging is a special case of image reconstruction in which the data are incomplete and noisy. In other fields, iterative reconstruction algorithms have been used successfully to improve the image quality. This paper studies the application of iterative algorithms in radar imaging. A discrete model is first derived, and the iterative algorithms are then adapted to radar imaging. Although such algorithms are usually time consuming, this paper shows that, if the algorithms are appropriately simplified, it is possible to realize them even in real time. The efficiency of iterative algorithms is shown through computer simulations.     

D－胺基半乳糖（D－galactosamine）对小白鼠肝脏的损害作用

给小鼠一次性腹注Ｄ－胺基半乳糖（Ｄ－Ｇａｌｎ）６００和１２００ｍｇ／ｋｇ，或１６小时内连续６次腹注３００ｍｇ／ｋｇ，停药后４８小时，血清谷丙转氨酶（ＳＧＰＴ）明显升高，局部肝细胞呈现肝炎病理形态改变。病变机理是过量Ｄ－Ｇａｌｎ入肝代替了尿苷二磷酸葡萄糖的代谢途径所引起的。     

墨法在中国传统书法艺术中的地位和作用

墨是中国传统书法艺术的书写原料，离开了它即无字形，离开了用墨的方法(墨法)，则形成不了书法艺术的深度和广度。因此，掌握好用墨的干湿浓淡，充分发挥好其对比作用，是不同书家、不同书体、不同墨法和不同风格的展现。墨法是传统书法作为一门艺术的法宝之一。     

新生态δ-MnO2对废水中As(v)的吸附研究

利用新生态δ-MnO2对含As(v)的模拟废水进行了吸附实验，结果表明，δ-MnO2对As(v)有良好的吸附特性，有较好的去除率．吸附前MnO2悬浊液的PH值、MnO2的投放量、As(v)的初始浓度、吸附时间、温度等对吸附效果都有一定的影响．却除的最佳条件为：室温下，PH值为6．5，MnO2投放量为100mg，As(v)的初始浓度为10mg／L，吸附时间为2h，去除率可达96％以上。
