The edge plasma fluctuation characteristics are studied by the fast reciprocating scanning 6-probes in the boundary region. These probes can measure edge plasma temperature, density, poloidal electric field, radial electric field, Reynolds stress, and their profiles in once discharges. Measurement results are used to analyze plasma confinement, turbulent fluctuations and their correlation characteristics during multi-shot pellet injection （MPI） , supersonic molecular beam injection （SMB1） and electron cyclotron resonant heating （ ECRH ） discharges.

基于工业摄像技术提出一种非接触测量传动轴动态轴功率的方法。首先设计了轴功率测量系统,提出了测量轴转速和轴转矩的方法。通过数字散斑的相关搜索和亚像素计算等手段,测得轴转速和转矩值,最终计算得出轴功率。为验证本文方法的测量精度,搭建了车载试验系统,并在底盘测功机上对其进行了实际测量试验。试验结果表明:提出的轴功率测量方法得到的结果与底盘测功机测量结果变化趋势一致,其相对误差平均值为9.37%。其中轴转速的测量范围可以覆盖整个过程,测量值波动较小,与底盘测功机测量结果基本一致,其相对误差平均值为0.73%,抗噪能力强;轴转矩的测量范围可覆盖部分高转矩,测量值波动较大,两者测量结果趋势一致,其相对误差平均值为15.15%,抗噪能力较弱。本文方法克服了一些传统测量方法的不足,为解决轴功率动态测量提供了一种新思路。

目的考察高低自我监控者在陌生人与熟人情境下的被洞悉错觉。方法用Synder自我监控量表从220名大学生中选出典型的高低自我监控被试。设计2个试验情境，采用“饮料识别”程序来考察被试的被洞悉错觉。试验一为熟人情境，典型高低自我监控被试分别为13名和17名。试验二为陌生人情境，典型高低自我监控被试分别为23名和18名。结果1．低自我监控被试在两种情境下，均存在明显的被洞悉错觉[熟人情境：（4．53±2．12）人，（2．53±2．45）人；t（16）=4．41，P〈0．05；陌生人情境：（4．33±2．93）人，（3．11±2．89）人；t（17）=2．11，P=0．05]；高自我监控者在熟人和陌生人情境下都无被洞悉错觉（t（12）=0．38，P〉0．05；t（22）=1．09，P〉0．05）。2．熟人情境中低自我监控组被洞悉错觉的强度水平[（2．00±2．17）人]显著高于高自我监控组[（0．23±1．87）人，t（28）=2．40，P〈0．05]，但陌生人情境下两组之间差异没有达到显著水平（t（39）=0．52，P〉0．05）。结论自我监控水平对被洞悉错觉有显著影响，人际情境对被试的被洞悉错觉的强度水平具有一定影响。
