Scienti fic Papers of ZHANG Yanzhong selected some of my academic papers. The book falls into two sections，namely Section of Chinese and Section of Western Languages （English and Russian），with each section subdivided into information technique，aeronautical engineering and strategy issue of development. Furthermore，my PhD thesis is included in this section.
Over the past .six decades，I studied theoretical physics （undergraduate） ，mechanical vibration，information technique，aeronautical system engineering and strategy issue of development successively. My lifelong academic career separates into the following four phases.
In the 1960s and 1970s，I dedicated myself to vibration，impact and mechanical failure research upon graduation and delivered a few papers. What could be found at the moment were only some summaries and work reports with ordinary quality. A couple of papers are taken in the aeronautical engineering part of the book as a record of the work completed in that period.
In the 1980s，I studied at Cambridge University mainly focusing on the information technique，such as signal processing，digital circuit and advanced algorithm，and published a number of papers at home and abroad. Though part of them was lost，dozens of papers are incorporated in the information technique part of the book.
In the 1990s，I was engaged in civil aircraft system engineering，airborne system engineering and avionics system. A portion of papers written during this period of time are added in the aeronautical engineering part of the book.
In the past decade，I was involved in strategy issue of development and presided over the implementation of national projects： "Large Aircraft" and "Aeroengine & Gas Turbine". Apart from that，I also headed the research on construction of a conservation-minded society，building an emerging industry system and promotion of R&D globalization. Considering the length of these project reports，only a few excerpts are included in the strategy issue of development part of the book.
