The paper presents a design of passive heat-switch between pressure tube and calandria tube of Thorium-based Advanced Nuclear Energy System.

提出了一种用于钍基先进核能系统压力管与排管之间的非能动热开设计方案。

Either of two decay products of thorium,mesothorium I,an isotope of radium,or mesothorium II,an isotope of actinium.

新钍钍的两种性生成物之一，即新钍1号，它是镭的同位素，或新钍2号，它是锕的同位素

A stepwise carbochlorination-chemical vapor transport(SC-CVT) technique is proposed for separation of thorium from mixed bastnaesite-monazite concentrate.

以氟碳铈矿-独居稀土矿为研究对象,采用分步选择性碳热氯化-化学气相传输反应(SC-CVT),实现钍与其它稀土元素的分离。

But an unexpected fact was noted: certain minerals( pitchblende, chalcolite, autunite) had a greater activity than might be expected on the basis of their uranium or thorium content.

但是一个意外的事实引起了我的注意：某些矿物质(青铀矿物质、铀云母或钙铀云母)活性比根据其铀或针含量所判断的要高。
