This is DDX Security . Who am I speaking with ?

这里是DDX保安公司，请问您是哪位？

For each default template , some of the DDX elements that can be customized are highlighted and examined .

对于每个默认模板，其中一些可以定制的DDX元素会突出显示。

Up to now , most of DDX measurement data performed are at around 14 MeV and below 8 MeV , since the mono-energetic neutron sources are available .

实验测量方面，在14MeV附近和8MeV以下能区，由于有很好的单能中子源，实验测量数据比较丰富。

On the other hand , the theoretical calculation results are different from each other with different light nuclear reaction models , therefore DDX measurement is necessary for checking and improving nuclear reaction models and evaluation nuclear data file at different energy region .

另外，利用不同轻核核反应理论模型得到的结果相互之间并不一致，因此，需要更多的不同能区的双微分截面实验测量数据来检验和改进理论模型与评价数据。

Double differential neutron emission cross section ( DDX ) is one of the most important nuclear data used in nuclear engineering design , particularly in nuclear device and neutron shielding design . However the evaluations and measurements of DDX is sparse .

次级中子双微分截面在核工程设计中，尤其在核装置和中子辐射屏蔽设计中是所需的重要核数据之一，而现有的实验测量和评价的双微分截面数据不多。
