The crystal structure of C4H4N8O14 has been determined by X-ray diffrac -tion method. The crystal recrystalized from blend solvents of dichloroethane and heptane is of colourless pyramids. It is monoclinic, belonging to the space group P21/n, with the following cell dimensions:a = 11.820, b = 6.162, c = 18.229A, β = 96.1°The data collection was carried out on diffractometer with CuKα radiation. The structure was solved by the direct method and refined by the full-matrix least-squares technique, using 2024 independent reflections. Its final R factor is 0.105. There are four molecules in a unit cell. Each molecule contains two nitroform groups and one nitramine group. The structural arrangements of the two nitroform groups are similar to one another. Owing to the strong electronegativity of the oxygen atoms in nitrogroups, the lengths of the three C-N bonds of nitroform groups are somewhat longer than the normal values. The configuration of the nitramine group is planar as expected.

数据收集系统是利用人造卫星中继地球环境资料的一种无线电遥测系统。近地卫星(如美国的陆地卫星、泰罗斯-N气象卫星)所属的数据收集系统一般都采取随机取数的方法。在这类系统设计中,电文碰撞规律是涉及到系统容量的重要问题。本文在古典概率的基础上,经适当修改,得到符合计算机模拟结果的理论公式。并提供针对不同系统方案的电文碰撞概率的计算方法。
