质量功能配置的修正结构及其数学描述

质量功能配置是现代企业管理中的一种有效工具，本简单总结了质量功能配置的研究与发展，指出了原来质量功能配置的过程转换中的不足之外，给出了基于面向对象分析思想的质量功能配置在生产控制中具体应用的新描述，提出了质量屋群，建立了相应的数学模型，最后总结了可深入研究的问题。

切勿以偏盖全

“盲人摸象”原为佛经故事．太平洋天文学会（ASP）会议集第311卷将一幅众瞽摸象之图印在该卷的封面上（图1）．这次学术会议于2003年7月27—30日在美国普林斯顿大学举行，会议讨论的内容为从斯隆（sloan）数学巡天所得数据探究活动星系核（AGN）的物理问题．     

PREPARATION AND USE OF 1—ETHOXYCARBONYLALKYLIDENE DIPHENYLPOL YSTYRYLPHOSPHORANES

1－Ethoxycarbonylalkyldiphenylpolystyrylphosphonium triflates can be easily prepared by quaternizing diphenylpolystyryl phosphine with ethyl 2-trifloxyalkanoates;base treatment of these polymer-supported phosphonium triflates affords 1-ethoxycarbonylalkylidenephosphoranes which are stable and undergo satisfactory Wittig reactions.     

STUDY ON THE TREATMENT OF 3—PHENOXY—BENZALDEHYDE INDUSTRIAL WASTEWATER WITH POLYMERIC ADSORBENT

In this paper,the two effluents from PBA (3-phenoxy-benzaldehyde) production process were treated by polymeric adsorbent CHA-111.PBA or PBC (3-phenoxy-benzoic acid) was recovered from the wastewater in the process of neutralization.As a secondary treatment method,adsorption with CHA-111 showed better efficiency than photocatolytic decomposition and solvent extraction.The optimal technological parameters were:adsorption:current velocity:2.0BV/hr(bed volume per hour),room temperature;desorption:current velocity:2.0BV/hr(bed volume per hour),room temperature;desorption:current velocity:1.0 BV/hr,80℃,8% sodium hydroxide aqueous solutions.In conclusion,99.9% COD in the neutralizing wastewater and 98.4% COD in the hydrolysis wastewater are removed successfully.     

Absorption Spectra of the 4f Electron Transitions of the Nd,Ho and and Er Complexes with 1—Cyclopyropyl—6—fluoro—1,4—dihydro—7—（4—ethyl—1—piperazinyl）—4—oxo—3—quinoline Carboxylic Acid

The absorption spectra of the neodymium,holmium and erbium complexes with 1-cyclopropyl-6-fluoro-1,4-dihydro-7-(4-ethyl-1-piperazimyl)-4-oxo-3-quinoline carboxylic acid hydrochloride in the presence of TX-100 have been shown. The characteristic absorption bands of the 4f electron transitions of the complexes are enhanced markedly.
