简介：空间D_G被构造，空间D_G的一些描述被给。古典Fourier被扩大到广义函数空间D′_G，这被显示出，它能连续地被嵌进Schwartz广义函数空间D′。它也被看那D′_Gis上的D′的最大的嵌入的潜水艇空间扩大Fourier，G，是D′_G的同胚到自己上。

简介：分发评价是很重要的以便基于这分布为参数或它的函数做统计推理。例如，在这个工作，我们与非光滑的辅助信息建议某变量的分发的一个评估者这个变量的对称的分布。一种变光滑的技术被采用处理非可辨的功能。因此，分布能基于弄平的辅助信息被估计。分发评估者的Asymptotic性质被导出并且分析。没有这些辅助信息，分发评估者基于我们的方法被发现比相应评估者显著地有效。一些模拟研究被进行说明建议评估者的有限样品表演。
