It is concluded that m = 2 tearing mode is produced by the current gradient. Ifoptimized current gradients are retained in the vicinity of q = 2 singular surface, the disruption can be avoided. There is no need to select current density profile on the whole plasma section.

结果表明这种不稳定性由q=2奇异面附近电流梯度的增大引起，因此只要在奇异面附近保持适当的电流梯度就可避免破裂发生，即对电流分布实行局部控制就可实现对破裂的抑制，并不需要去选取某种特定的整体分布。

There are three main methods in face localization: localization according to face outline, localization according to complexion and localization according to templates constructed by some standard sample images. As to feature extraction, it can be divided into two parts because face features can be divided into geometrical features and algebraic features. While extracting geometrical features, the features of eyes, nose, mouth, eyebrows can be gained by some image processes: binary, sharpen, smooth, projection, calculating gradient and so on. In order to extract algebraic features, we can do some mathematical transformation for the digital images such as singular value decomposition, K-L transformation.
