线阵CCD在双棱镜测光波波长中的应用

CCD是一种以电荷量表示光量的大小,用耦合方式传输电荷量的新型光电传感器件,其基本部分由MOS光敏元列阵和读出移位寄存器组成.具有体积小、重量轻、功耗低、光谱响应范围宽、分辨率高、精度高、稳定性能良好等一系列优点,与计算机配合使用,使得由CCD采集到的大量数据的处理变得非常容易.对测量数据的处理可以经过存储、自动补偿和校正,最后打印输出,现今已在航天、遥感、军事设备、自动控制、雷达、医学、生物、化学、颜色测量等方面得到了广泛的应用[1].我们将其用在实验教学中,取得了很好的效果.     

Electronic Properties of Red P-Type Tl2S5 Single Crystals

Single crystals of red Tl2S5 were prepared by a special modified vertical Bridgman and Stockbarger technique.This growth was performed in our laboratory. The influences of temperature on the electrical conductivity, Hall mobility, carrier concentration, and thermoelectric power (TEP) were carried out in the temperature range 277-413K. Throughout these measurements, various physical parameters such as effective mass of charge carriers,carrier mobility, diffusion coefficient, and the relaxation time for both majority and minority carriers were found.

Indriect Determination of CTMAB with Sodium Chloride and Ammonium Thiocyanate by Floatation and Separation of Zine

A new method for indirect determination of cetyl-trimethyl ammonium bromide (CTMAB) with NaCl and NH4SCH by floatation and separation of zinc has been studied.The study shows that Zn(Ⅱ） can associate with NH4SCN and CTMAB to form insoluble ternary ion-association complex,and the precipitate can float on the surface of the liquid phase.A good linear relationship is observed between the floatation yield(E%) of Zn(Ⅱ） and the amount of CTMAB.On the ground,CTMAB Can be indirectly determined by determining E% of Zn(Ⅱ）.The results were satisfactory.

双预脉冲驱动X射线激光实验研究

 在“星光-Ⅱ”激光装置上进行了双预脉冲驱动类氖铬X射线激光实验，介绍了实验方法和实验结果，并对结果进行了简短讨论。由于目前“星光”装置输出能量较低，所进行的双预脉冲驱动未能显著提高X射线激光强度，改变预脉冲幅度时X射线激光强度也未有显著变化。利用MED103程序进行了模拟计算，其结果与实验结果一致。

Pt-SDB疏水催化剂的研制

基于液相水-氢同位素催化交换的疏水催化剂研究已有近30年历史。从所报道的资料来看，目前用于重水提氚工艺中相转移的疏水催化剂主要集中在Pt-C-PTFE和Pt-SDB两类材料上。前者疏水性好，耐辐照稳定性好，后者催化活性好，但催化剂耐辐照稳定性稍差。拟在特制的SDB疏水材料上制备出催化活性好，性能稳定，满足使用要求的Pt-SDB疏水催化剂。
