Main contents and conclusions are: 1 The ionization current was measured continuously by a charge-integration method with a computer after the introduction of radon into the chamber.
主要内容及结论:1充氡后利用计算机连续进行电离电流累积测量,得到了精细的电流随时间的变化曲线,可清楚看出氡及其子体的生成衰变造成的电离电流的生长—稳定—衰减过程,与理论计算值进行了比较,由电离电流衰减速度的变化得出氡吸附作用的影响,并测量到电离室冲洗后氡的反扩散现象;2由已知活度的标准源定出相对测量的刻度系数K值,K=24.62 Bq/pA,对同一个监测源以半年为周期进行多次测量后得出稳定性符合要求;3通过测量电离电流和气压的关系曲线以及不同气压下的饱和曲线,确定了常规的工作条件;4测量了盐酸清洗电离室内表面降低本底的效果;5不确定度分析表明相对测氡的扩展不确定度(k=2)小于5%,由本底涨落得出探测下限为0.5 Bq;6理论上对壁损失修正进行了计算,实验上保持电离室工作在饱和区的情况下,测量了不同气压下电离电流的变化,从中得出了壁损失随气压变化的规律,可以看出,电离电流的实测值和计算值随气压变化规律基本一致;当气压大于125 kPa时,端效应等其它因素造成的影响不大于2%,因而在此工作条件下,测量电离电流后通过计算修正壁损失可以实现近似的绝对测氡,提出了进一步提高绝对测量准确度的方法。

The results of calibration of 4He in desorption system show that the correlation coefficient is more than 0.99 and the contribution of memory effect can be ignored. The contribution of ionized atom T(superscript +) for partial pressure of m/e=3 is very little and is determined according to I+≈0.01I(subscript T2)+, so the measurement of 3He can be done without interference of T(superscript +). The relationship between gases release rate and annealing temperature can be obtained after the data are smoothed and differentiated.
研究结果表明:四极质谱计标定解吸系统内4He的分压<350 Pa时,其相关系数R>0.99,且记忆效应的贡献极弱;离子态氚T对m/e=3组分分压的贡献可按I+≈0.01I(下标 T2)+确定,不干扰3He的测定;将气体解吸所得的积分数据经平滑并微分处理后可准确得到气体释放速率与退火温度的关系,即热解吸谱。

That the location of the airport帕希姆happens to be in the center of Europe, from Hamburg, 120 km, Berlin 160 km, between the two major German cities have a sea port of iron supply and rail systems, but there is no air transport hub, Pa Fahim stop at the airport between the two cities, while Hamburg is Europe's second largest port, and the Baltic port of Rostock, Wismar, Lübeck circle at the airport, 100 km range, have a direct rail link, the multimodal transport is that it combines the advantages of.
庞玉良认为帕希姆机场的所在位置刚好是在欧洲中心,距汉堡120公里,柏林160公里,两个主要德国城市之间都有海、铁的货源的港口与铁路系统,但没有空运枢纽,帕希姆机场罢处于两城市之间,而汉堡又是欧洲第二大港口,而波罗的海港口罗斯托克、维斯玛、吕贝克在机场圈100公里范围之内,有铁路直接联系,这种多式联运结合是它的优势。
