怎样才能及时地预报地震?要解决这个问题,正如专家们认为的那样,需要具备能捕捉到震前微弱物理现象的仪器。例如,学者们业已查明,在自然灾害发生之前,土壤和空气中的沼气含量会增加。但是,要作出这方面结论,需要连续不断地在大范围内进行观测。为达此目的,采用传统的 How to predict the earthquake in time? To solve this problem, as experts think, it is necessary to have the equipment to capture the weak physical phenomena before the earthquake. For example, scholars have identified that biogas content in soils and air will increase before natural disasters occur. However, in order to make this conclusion, it is necessary to observe continuously on a large scale. To this end, traditional
