Ecological aspects of the manufacture and application of highly pure liquid substances

The action mechanism for aggressive and highly pure media on fluoropolymer constructional elements is assumed to consist of two basic microeffects: destructive changes in the fluoropolymer and contamination of the environment. Our approach to a quantitative estimation of the physicochemical stability is based on logic similar to that of a thermodynamic model of a two‐component system. A fluoropolymer and changes in its microstructure are considered the first component of the system. The second component is composed of liquid media contaminated with fluoroorganic compounds extracted from the fluoropolymer. The proposed methods for delivering aggressive and highly pure fluids to consumers allow the exclusion of pollution from working areas with gaseous products through an exception to a number of intermediate stages of product transport. The discussed principles allow the creation of a modern, highly effective, and safe (with respect to the ecology and raw materials) production of aggressive liquid chemicals for consumers. © 2002 Wiley Periodicals, Inc.

含油污泥焦化处理实验研究

采用焦化方法对含油污泥进行处理。经过筛选选取活性白土作为焦化处理催化剂,分别研究了反应时间、反应温度、氮气吹扫量、加热速率等因素对处理效果的影响。4个影响因素对液相油品收率的影响顺序为:氮气吹扫量>反应温度>反应时间>加热速率;对反应转化率的影响顺序为:反应温度>反应时间>氮气吹扫量>加热速率。较为理想的反应参数:反应温度490℃;反应时间60min;氮气吹扫量90mL.min-1;加热速率4℃.min-1。在此反应条件下,含油污泥液相油品收率>80%,反应转化率>99.9%,经焦化处理后的废渣含油率<3‰,达到农用污泥排放标准,实现了达标排放和回收资源的目的。

Astaxanthin Extraction From Shrimp Waste by Lactic Fermentation and Enzymatic Hydrolysis of the Carotenoprotein Complex

ABSTRACT: Natural carotenoids are an alternative to synthetic orange-red pigments. They are present in crustaceans as a protein-pigment complex. In order to extract this highly unstable pigment, crustacean waste must be stabilized; lactic fermentation is a simple and environmentally friendly method to achieve this goal. Shrimp wastes were inoculated with Lactobacillus bacterial cultures. Carotenoids were then extracted with an organic solvent system. Protein-pigment splitting was carried out using a mixture of 4 commercial enzymes; and the protein was separated from the pigment by ultrafiltration. Electrophoretograms showed that the pigment was attached to a 265-kDa protein. Splitting the protein-pigment complex allows studies on pigment absorption, stability and application.     

线性联合检测算法在TD-SCDMA系统中的性能分析与比较

时分、同步码分多址（TD－SCDMA）系统是基于时分双工（TDD）的块传输系统，它使用了联合检测这项关键技术来抵抗符号间干扰（ISI）和多址干扰（MAI）。以上行链路为例，本文分析了三种线性联合检测算法－－匹配滤波块均衡器（MF－BLE）、迫零块均衡器（ZF－BLE）和最小均方误差块均衡器（MMSE－BLE）。从理论上，我们描述了这三种线性联合检测算法的基本原理，并对它们进行了比较（包括抗干扰性能和计算量）。随后，我们模拟了不同参数条件下（信道模型、码道数目、天线数目）这几种算法的性能，并与理论分析进行对照，得出一定结论。
