关于复阻尼理论的几点注记 总被引:7,自引:0,他引:7
给出了复阻尼本构方程在全频域的表达式,完成了向时域表达式的转换。中指出,基于Fourier频域的本构不能用于求解由初值确定的自由振动,只有延拓至复频域,才具备概括自由振动与强迫振动两种工况的能力。为了满足热力学定律的约束,对复频域本构必须附加限制条件。离散计算时,由于未实施这一限制条件,一定会导致失稳。中对解决失稳问题提出了若干建议。 相似文献

Environmental management of military activities is of growing global concern by defence forces. As one of the largest landholders
in Australia, the Australian Defence Force (ADF) is increasingly concerned with sustainable environmental management. This
paper focuses on how the ADF is maintaining effective environmental management, especially in environmentally sensitive marine
protected areas. It uses Shoalwater Bay Training Area (SWBTA) as a research example to examine environmental management strategies
conducted by the ADF. SWBTA is one of the most significant Defence training areas in Australia, with a large number of single,
joint and combined military exercises conducted in the area. With its maritime component contained in the Great Barrier Reef
Marine Park (GBRMP), the Great Barrier Reef World Heritage Area (GBRWHA), and abutting Queensland’s State Marine Parks, it
has high protection values. It is therefore vital for the ADF to adopt environmentally responsible management while they are
conducting military activities. As to various tools employed to manage environmental performance, the ISO 14001 Environmental
Management System (EMS) is widely used by the ADF. This paper examines military activities and marine environmental management
within SWBTA, using the Talisman Saber (TS) exercise series as an example. These are extensive joint exercises conducted by
the ADF and the United States defence forces. The paper outlines relevant legislative framework and environmental policies,
analyses how the EMS operates in environmental management of military activities, and how military activities comply with
these regulations. It discusses the implementation of the ADF EMS, including risk reduction measures, environmental awareness
training, consultation and communication with stakeholders. A number of environmental management actions used in the TS exercises
are presented to demonstrate the EMS application. Our investigations to this point indicate that the ADF is complying with
all relevant legislation and policies. Further research is required to confirm compliance and conclude that military activities
have good accord with environmental management objectives. 相似文献
