Undoubtedly, the international environment that China faces remains changeable, thus arousing some problems with which people are not familiar or great changes have taken place in the background and condition. In this sense, it is absolutely an uneasy job to make a deep analysis of today’s international environment. In particular.

因隧道安装防火板,导致渗漏水隐蔽在防火板背后而不易被检测。红外热成像技术是一种非接触无损检测技术,因其对表面热辐射敏感而常用来测量表面温度场。基于红外热成像技术,研究了隧道隐性渗漏车载非接触式快速检测的可行性。结合某长江隧道,将红外热成像设备安置在车顶,对隧道内表面实施移动扫描拍照,并通过红外热力图准确识别既有渗漏点。为了进一步验证检测效果,人为在防火板表面涂湿模拟渗漏,该渗漏过程可以被准确识别。通过试验研究,表明红外热成像技术用于隧道隐性渗漏车载非接触式快速检测是可行性的。

The development of international military situation in 2o17 has been consistent with that of the past few years. While the overall situa- tion is stable, there has been frequent re- gional turmoil with traditional and non- traditional security risks intertwined, and rising uncertainties in international security The evolvement is closely as- sociated with the profound changes in international system and greatly affects the global landscape. In such a turbu- lent period, strategic stability is still tak- ing hold in major country relations as the strategic balance is maintained and effective instead of deviating from the right path.
