During the impurity radiation, the density perturbation driven by density gradient couples with the temperature one and then affects the electrostatic potential one.

电子密度梯度直接影响密度涨落，并通过杂质辐射与温度涨落相互耦合，进而影响静电势涨落。

The energy equation is solved by the zonal method, and the inverse radiation problem is solved through the minimization of performance function with the conjugated gradient method.

采用段法(区域法)求解正问题，反演中采用求目标函数极小值的共轭梯度法。

During the accumulation season, sublimation is reduced because of a low gradient of vapour pressure and the energy supplied by radiation is directly consumed by melting, explaining why discharge is high.
