Ionosphere is the main place for people to explore outer space,many spacecraft satellites and detectors are working here,so it's very important to monitor space weather.And 83.4nm emissions is the strongest emissions among the emissions in the Extreme Ultraviolet.We can get the optical signals from the remote sensing of the neutral particles?N2,O2,O?of the ionosphere.In this paper,we give a method of calculation 83.4nm emissions,and hope it would provide a support to the simulating image of ionospheric 83.4nm dayglow.The paper contain four main section.Firstly,we introduce the ionosphere and the meaning of launching satellites to the space.And then we give a detailed introduction to the basic form of ionosphere.Then introduce some detectors of representative and compared with our country.Finally the meaning of this paper and the study is given.The second part mainly introduces the theoretical knowledge of radiation transfer.Firstly the commonly used physical quantities in radiation field and radiation transfer are given,and described them in detail.Then we introduce the basic derivation of radiation transfer equation,and the assumptions that satisfy the equation.The third part is the focus of this thesis,explain the calculation method of radiation in detail.The research methods of radiation transfer algorithm by other people are given,then give the method that calculated by myself.It mainly includes the production mechanism,transmission mechanism and the conditions to be satisfied by the model establishment.In solving the radiation transfer equation,matrix solution is adopted and the calculation results are given.At the same time,the correctness of the algorithm is verified by comparing with Anderson's calculation results.Then the calculation results under MSISE-00 are given.The fourth part is the application of the calculation method in the third part.Calculate the limb radiation intensity and the global radiation intensity distribution under the condition that the optical depth doesn't change with the geographic latitude and longitude.Finally thesis summarized and prospected.
