Abstract—In the future communication applications, users may obtain their messages that have different importance levels distributively from several available sources, such as distributed storage or even devices belonging to other users. This scenario is the best modeled by the multilevel diversity coding systems (MDCS). To achieve perfect (information-theoretic) secrecy against wiretap channels, this paper investigates the fundamental limits on the secure rate region of the asymmetric MDCS (AMDCS), which include the symmetric case as a special case. Threshold perfect secrecy is added to the AMDCS model. The eavesdropper may have access to any one but not more than one subset of the channels but know nothing about the sources, as long as the size of the subset is not above the security level. The question of whether superposition (source separation) coding is optimal for such an AMDCS with threshold perfect secrecy is answered. A Class of secure AMDCS (S-AMDCS) with an arbitrary number of encoders is solved, and it is shown that linear codes are optimal for this Class of instances. However, in contrast with the secure symmetric MDCS, superposition is shown to be not optimal for S-AMDCS in general. In addition, necessary conditions on the existence of a secrecy key are determined as a design guideline.

在国内Protel软件一直大受欢迎，从DOS时代的Protel3.3(Autotrax 1.61)到现在具有EDA Client/Server （客户/服务器）即C/S“框架”体系结构的Protel98，它始终是PCB设计和制造领域的大众化工具软件，成为电子设计工作者们的首选。 在规范化的设计管理中，设计文件图样必须遵守相应的国家标准，如《电子产品图样绘制规则》、《设计文件管理制图》和《印制板制图》等，而由于Protel软件都是英文版，因此无法直接打印出符合国家标准的图纸，要将图纸规范化常用的方式是套打，即先将符合国家标准的表和汉字等打在纸上，再将该纸放入打印机，用Protel软件将印制板图打印其上，形成符合标准的文件，但这种做法效率很低，而且图形常会打偏，有时甚至会打反，经笔者试验，找到了一种简便的方法，使印制板图转换为AUTOCAD格式，再在AUTOCAD里一次性打印出符合标准的图纸。

IGBT(Insulated Gate Bipolar Transistor)，绝缘栅双极型晶体管，是由BJT(双极型三极管)和MOS(绝缘栅型场效应管)组成的复合全控型电压驱动式功率半导体器件, 兼有MOSFET的高输入阻抗和GTR的低导通压降两方面的优点。GTR饱和压降低，载流密度大，但驱动电流较大;MOSFET驱动功率很小，开关速度快，但导通压降大，载流密度小。IGBT综合了以上两种器件的优点，驱动功率小而饱和压降低。
