COIL中BHP浓度对发生O_2(~1△)的影响

本文实验研究了BHP的浓度对产生O2（1△）的影响。实验结果表明：当BHP浓度大于3.5M时，Cl2利用率以及O2（1△）的产率将不依赖于BHP浓度的变化而变化，同时，实验结果表明，使用低浓度的BHP对COIL的操作是可行的。

交联剂在碳／碳复合材料沥青基体中的作用

本文从C/C复合合材料的基体入手，分析了交联剂在沥青中的交联机理，并以此为基础对中温煤沥青在催化剂作用下进行交联反应。结果表明，交联剂在C/C复合材料基体中的交联作用非常明显，不仅基体本身的残碳率及耐热程度有很大提高，而且，以它制成的C/C复合材料的抗压强度也有显著增加。     

铝合金铁相团球化熔剂的研制

研制了一种铝合金铁相团球化熔剂，在含铁量较高（１．０％－４．０％Ｆｅ）的铝合金中加入该熔剂后，可使针片状的铁相变为团球状或颗粒状组织。从而大幅度提高原合金的机械性能，δｂ和δ分别提高２０％－９０％和４０％－１００％。生产实验表明：该熔剂团球化效果好（具有长效性），极便于在生产中推广应用。     

A study of impact toughness of Fe-Cr-X damping alloys

A study was carried out on the impact toughness of Fe- Cr- Х damping alloys. Two measures proved to be effective in improving impact toughness. One was to lower carbon plus nitrogen content to an ultra- low level. This method is suitable for single- phase ferrite alloy. The other is to use dual- phase damping alloys. The presence of martensite in Fe- Cr- Х alloys can enhance impact toughness remarkably, but lower damping capacity drastically. This shows the importance of achieving balance between mechanical prop-erties and damping capacity by properly controlling martensite volume fraction in dual- phase alloys.

激光器绝热啁啾对光纤通信系统传输特性的影响

通过理论分析、实验和计算机模拟得到：进行直接强度调制时，体块型DFB激光器的总微分量子效率（与多量子阱DFB激光器相比）过低，从而导致其绝热啁啾占激光器啁啾的主要部分；用于无再生中继距离较大的强度调制／直接检测（IM／DD）光纤通信系统时，色散效应将导致信号脉冲上升沿压缩，使系统误码率增加。据此建议：在无再生中继距离大于100～120km的常规单模光纤IM／DD系统中，应采用多量子阱激光器。     

Extraction of halide quaternary salts in an organic solvent/water system: Hydrodynamics and mass transfer

The hydrodynamic characteristics and mass transfers of halide quaternary salts between two immiscible phases in a stirred membrane permeation cell were investigated. The concentration of quaternary salt, temperature, solvent and the four kinds of halide quaternary salts were evaluated to achieve the extractive optimum condition. The diffusivity, overall mass‐transfer coefficients and individual mass‐transfer coefficients were determined and correlated in terms of the conventional Sh‐Re‐Sc relationship. The transfer time of quaternary salts across the membrane and the thickness of the hydrodynamic diffusion boundary layer were determined as well, so as to characterize the extractive phenomenon of quaternary salts between the two phases that is useful in phase‐transfer catalysis.
