探测器

The activity of thorium was measured by using a HPGe detector and a planar HPGe detector. 238 Th has been identified for the first time by measuring the growth and decay of the γ rays from its daughter nucleus 238 Pa.

使用两台高纯锗探测器测量了样品的γ射线活性，观测到了238Th的β－衰变子体238Pa的γ射线的生长、衰变行为，测定238Th的半衰期为9.4±2.0min

Dr Renno thinks that when the craft settled, its thrusters melted some of the ice and the resulting mud splashed onto the leg. The perchlorates in the mud then sucked moisture out of the air until there was enough water for them to dissolve (a process known as deliquescence).

Renno博士认为，当探测器降临在地面上时，用来矫正姿态的助推器融化了一些冰块，因此产生的一些烂泥溅落随后在机械臂上，然后泥巴中的过氯酸盐因为从空气吸收了足够的水气而溶解。

Based on synthetic analysis of network resource, the QOS parameters and their characters, the high requirement of real-time synchronization in NCW, the single QOS routing constraint, and the network latency between the detector and weapon control station, are presented.

在综合分析网络资源状况和服务质量度量参数的基础上，结合网络中心战对实时性要求较高的特性，提出了以探测器到火力控制单元的网络时延作为服务质量选路标准。

To take an example for 3-node brigade level NCW demonstration platform, the algorithm of end-to-end network latency and path information in NCW are presented. The algorithm program based on Server/Client architecture is developed. The optimal path is the link whose latency between the detector and weapon control station is the smallest.

以3节点旅级网络中心战演示实验平台为例，提出了一种计算网络中心战架构中端到端时延和获取路径信息的算法，开发了Server/Client架构计算程序，选取探测器到火力控制单元之间的最小网络时延的链路作为最优路径。
