徐州市霾天气监测预报预警平台设计

为了满足徐州市气象观测和预报的需求,采用基于MFC单文档C/S结构进行软件设计,让用户仅使用客户端程序即可完成所有操作。软件开发使用Microsoft VC6.0编程工具,并在平台上配置了Open CV用作图像处理,采用的编程语言为C++。平台的各类人机交互操作、信息查询、图形操作等能实时响应;信息查询、操作、输出界面用图形、文字和数据三种方式在计算机上展现。开发出集徐州市霾天气的记录、监测、预报、预警等功能为一体的平台,经过实践检验,该软件可以较好地适用于气象、环保等相关部门。对公众愈加关注的霾天气预报提供技术支持,为徐州市霾的预测、防治及其影响评估提供了充分的科学依据。

Heating of the Electrons and the Rectified Current at the Contacts That Are in an Alternating Electromagnetic Field

The paper deals with the heating of electrons and current rectification in contact, which is located in an alternating electromagnetic field. It was found that the electrical component of the microwave (UHF) waves inside the p-n-junction was curved. This leads to the perpendicular component of the electric field of the microwave wave. This component modulates the height of the potential barrier with the frequency of the microwave. In the p-n-junction, straightening microwave current occurs. It is shown that the rectifying contact in the microwave electromagnetic field is always an electromotive force. This is due to carrier heating and straightening microwave current. It is shown that electron heating and straightening of the microwave power will lead to higher ideality factor of the diode.
