sub-harmonic radiation

As a sub-nanosecond and pulse radiation detector, GaAs photoconductor detector has a very wide application foreground.

砷化镓光电导探测器作为一种亚纳秒脉冲辐射探测器有很广的应用前景。

According to the mechanisms of inter-building fire-spread, the latter sub-model formulates two main fire-spread ways, i.e. thermal radiation and thermal plume heating, respectively by simplifying and modifying pervious theory-based models. Additionally, it also quantifies the weather conditions which have great effect on inter-building fire-spread.

后者则是从建筑物间火灾蔓延的机理入手，借鉴已有模型对两种主要的火灾蔓延方式热辐射与热对流进行模型的简化和修正，并且量化了影响建筑物间火灾蔓延的气象条件。

China will also check all imported products for radiation, and release information about sub-standard products.

中国还将对所有进口产品进行放射性物质检测，不合格的按规定予以公布。
