透湿膜的透湿机理与膜的研究概况

基于透湿膜的空气除湿是一种比较新颖的空气除湿方法。本文介绍了各种膜在空气除湿领域的应用情况，结合对膜制备工艺的简要介绍，侧重对原除湿原理，亲水性的高分子纤维素膜，凝胶膜和分子筛无机膜在空气除湿领域的研究和进展进行了分析。     

CHARACTERIZATION OF Si_(1-x-y)Ge_xC_y FILMS GROWN BY ION IMPLANTATION AND SUBSEQUENT SOLID PHASE EPITAXY

Si1-x-yGexCy ternary alloy films were grown on monocrystalline silicon substrates by C ion implantation and subsequent solid phase epitaxy (SPE). Two-step anneal-ing technique was employed in the SPE. The structure and electrical properties of the alloy films were determined using Fourier transform infrared spectroscopy and van der Pauw Hall measurements, respectively. With the optimization of two-step anneal-ing technique for the implanted Si1-x-yGexCy layers, a certain amount of C atoms occupied substitutional sites and no SiC was formed.     

Rapid Development of China''''s Offshore Oil Industry

Founded on February 15, 1982, China NationalOffshore Oil Corporation (CNOOC) has experiencedtwo decades of rapid development, in which theannual offshore oil production rose dramatically to23. 13 million tons in 2001 from 90,000 tons in 1982while the total assets jumped to 72 billion yuan from2.8 billion yuan, but the total employees dropped to21,000 people from 30,000. This offshore oil giantgenerated a profit of 9.2 billion yuan in 2001 andturned over 4 billion yuan in taxes to the State…

纳米4-H碳化硅薄膜的掺杂现象

对纳米晶SiC薄膜进行了P和B的掺杂,B掺杂效率比P高,其暗电导预前因子与激活能遵守Meyer-Neldel规则,并有反转Meyer-Neldel规则出现.掺杂效率比非晶态碳化硅薄膜高是纳米碳化硅薄膜的特点之一.非晶态中的隧穿和边界透射对输运有一定贡献.     

八闽奇胜"安贞堡"

安贞堡坐落于福建省永安市槐南乡洋头村。清光绪十一年(1885)始建,于清光绪二十四年(1898)竣工。占地面积一万平方米,三进院落沿中轴线上布有18个厅堂、12个厨房及大小三百多间房间,可供千余人居住。而高9米、厚4米用厚石垒砌加生土夯制而成的外墙上,设有198个射击孔,96个了望窗守护着堡内主人的安危。安贞堡是福建省一座罕见的晚清时期大

本文介绍了用标准液体源均匀充入聚氯乙烯制的体模,刻度标准椅全身计数器〔φ8″×4″(NaI)〕的方法和结果。分别就代表6个年龄组的体模,测定了标准椅全身计数器对5种能量(364,637,898,1460和1836keV)γ射线的全能峰效率;给出了全能峰效率与γ射线能量和被测对象体重的关系曲线。     

梅毒螺旋体血凝试剂盒的研制

以超声波处理的梅毒螺旋体为抗原,致敏经醛化、鞣化处理的绵羊红血球,应用血凝试验检测梅毒患者血清中梅毒螺旋体特异性抗体。同时以国际上公认的标准方法——FTA-ABS作为对照试验。共检测1125份血清(其中梅毒血清205份,非梅毒血清920份).两种方法检测结果完全相符,即敏感性皆为100％,血凝试验的特异性为99％。
