无线通信中，接收端对截获的人为干扰进行有效地分析和识别，为通信系统的综合抗干扰决策提供信息支援，对于提高通信系统抗干扰能力具有重要意义。针对人为干扰分析的实时性和干扰识别的准确性，提出了基于短时傅里叶变换（ STFT）的时频分析方法，在时频域对干扰信号进行分析和识别；针对由于复杂人为干扰的特征参数不同带来参数提取的困难，提出了基于信干比变门限法提取人为干扰参数；针对自然噪声等随机干扰影响人为干扰参数提取准确度的问题，提出了时频干扰数据频率二次采样的方法。理论分析和仿真结果表明，一方面，短时傅里叶变换法能够较好地对给定的复杂人为干扰进行参数提取，并能够通过频率的二次采样在一定程度上消除随机干扰的影响，另一方面，变门限法对于复杂人为干扰特征参数的提取有较好的效果。

In wireless communication, the receiver efficiently analyzes and recognizes the intercepted jam-ming,and provides information assistance for the total anti-jamming decisions of the communication systems, this is very important in developing the anti-jamming ability of the communication systems. For real-time a-nalysis of the jamming and accurate recognition of the jamming styles, the short-time Fourier transform ( STFT) algorithm is proposed to analyze and recognize the jamming. Aiming at the difficulty of jamming pa-rameters recognition resulted from the different complicated jamming parameters, the threshold-varying based on signal-to-jamming ratio is suggested to get the jamming parameters. As for the influence on recog-nition accuracy of jamming parameters by random disturbance, such as the white noise, the second frequency sample is presented. The simulation results show that the STFT algorithm could recognize the given compli-cated jamming efficiently and decrease the random nois

人为灾害与自然灾害相对,是因人为致灾因子或相关主体脆弱性而引发的灾害。技术灾害是人为灾害主要形式之一。技术灾害的研究经历了从注重相关主体脆弱性(即灾害原因)到构建相关主体韧性(即应灾措施)的两个阶段。从经济学角度分析,人类需求与技术选择是技术灾害发生的根源;而企业经济利益动机则是导致技术灾害的主要人为原因。除此之外,经济集聚效应和贫困也是影响技术灾害风险的重要因素。"树立科学经济发展观、构建相关主体韧性"是减灾的基本策略。

Compared with natural disasters, man-made disasters are those, which are induced by man-made hazards or the related institutions’ vulnerabilities. Technological disasters are one of the main forms of man-made disasters. The study on technological disasters has experienced two stages, from focusing on the relevant institutions’ vulnerabilities (reasons of di-sasters) to constructing the relevant institutions’ resilience (measures to respond to disasters) . From an economic perspec-tive, Human needs and technology choice are the root causes of technological disasters, and the corporate economic motiva-tion is the main man-made disasters inducement of technological disasters. In addition,economic agglomeration effect and pov-erty are also the important factors related to the risk of technological disasters. The basic strategy for disaster reduction is to es-tablish the scientific outlook of economic development and build the relevant institutions’resilience.

影响性诉讼在我国当前的法治实践中屡见不鲜，正确认识影响性案件的特点、种类、成因，掌握影响性案件的应对策略和裁判方法，对于促进裁判的可接受性具有重要意义。影响性诉讼从形成原因上可以划分为天然影响性诉讼和人为影响性诉讼。无论是天然影响性诉讼，还是人为影响性诉讼，司法机关都要审慎地识别和规避其中蕴含的消极影响，积极利用其中蕴含的法治创新因素促进个案积极影响的最大化。正确应对影响性诉讼，必须以追求法律效果和社会效果的统一为目标，以构建专业的司法和非专业的民意之间的沟通机制为路径，推动我国的司法迈向回应型司法。

The impact litigations are very common in China’s current judicial practice. To correctly understand the features, types, causes of impact litigations and to master the coping strategies and the judicial methods of the impact litigations are of great significance to promote the acceptability of the judgments. The impact litigation can be divided into natural and factitious impact litigation from the forming reasons. Whether natural or factitious impact litigation, judicial organs should carefully identify and avoid the implied negative impacts and actively take advantage of the implied law innovation factors to maximize the positive impact of the case. In order to correctly cope with the impact litigation, we must aim to the unification of the legal effect and social effect, build the communication mechanism between the professional justice and non-professional public opinion as the path, and push our judicature towards the responsive judicature.
