Our achievement in the academic year of 1996 is summarized as follows.[1] Diagnostic innovation :We have established a generalized scheme for optically determining the correct temperature of gray materials placed in atmospheres different from that of an infra-red camera which implicitly requires that the ambient temperatures are equal to that of the camera.The new scheme leads to the true temperature of the plasma-facing gray objects whose infra-red images are transferred through several optical components to the camera that displays an apparent temperature distribution strongly affected by emissivities, reflectivities, and transmittances of the components so that erronious results are obtained without the correction.This achievement is published in Rev.Sci.Instrum. (1997).[2] Experimental findings :(1) The radial energy flux is observed to reach dominantly to the coil wall that is the nearest to the plasma edge. It indicates that the radial flux is carried by electrons bouncing fast axially in the mirror field and kicked radially by a heating wave when passing through the resonance layr.(2) Both the radial flux and the axial flux of the plasma energy increase almost proportionally to the heating power in the plug. This observation indicates that the mechanism of potential formation in the plasma is closely linked with the 3-dimensional transport of electrons under heating waves.

我们在1996学年的成就概述如下。[1]诊断创新：我们已经建立了一个通用的方案，用于光学确定放置在不同于红外相机的大气中的灰色材料的正确温度，该方案隐含地要求环境温度等于相机的温度。新方案导致面向等离子体的灰色物体的真实温度，其红外图像通过几个光学元件传输到相机，该相机显示受发射率，反射率和透射率强烈影响的表观温度分布，因此无需校正即可获得准确的结果。该成果发表在Rev.Sci.Instrument上。（1997年）。[2]实验结果表明：（1）径向能流主要到达离等离子体边缘最近的线圈壁。结果表明，径向磁通量由在镜场中快速轴向反弹的电子携带，而在通过谐振层时被加热波径向踢出。(2)等离子体能量的径向通量和轴向通量几乎与塞中的加热功率成比例地增加。这一观察结果表明，在等离子体中的电位形成的机制是密切相关的加热波下的电子的三维输运。
