几何布置对核料位测量性能影响的实验研究

Experimental Studies of the Effect of the Geometrical Arrangement on the Nuclear Level Measurement Performance

为了研究几何布置对核料位测量工作性能的影响,并找出最佳的布置方式,分别对三种实验装置几何布置进行了实验模拟。结果表明,吸收法精确度最高,散射法次之,工作曲线法最差;从实验过程来看,吸收法和散射法需测多组数据才可得出料位位置;而工作曲线法,当作出工作曲线后,只需测一组数据,就可得出物料的料位位置,此方法更方便、简单和省时。

In order to study the effect of the geometric arrangements on the nuclear level measurement perform -ance and find out the best arrangement , the three experimental device geometrical arrangements were experi -mentally studied .The results indicate that the absorption method is of the highest accuracy , the second is the scattering method , the lowest is the working curve method .However , judging from the experimental process , the absorption and the scattering method need subgroup date , while the working curve method only need one set of date.So the working curve method is simple , quick and time-saving comparing with others .
