Experim.nts on form.tion of spherical tokam.k (ST) plasm.s by electroncyclotron heating (ECH) alone without a central OH solenoid have been carried out on LATE (LowAspect ratio Torus Experim.nts). By injecting a 2.45 GHz m.crowave pulse of 6.3 kW for 4 seconds, aplasm. current is initiated and ram.ed up to I_p approx= 3 kA, and finally m.intained for 1 secondby adjusting the external vertical field. m.gnetic m.asurem.nts show that closed flux surfaces areform.d and the last closed flux surface has an aspect ratio of A ～ 1.3 and an elongation of κ～1.3. The electron density m.asured by an interferom.ter is m.re than 1.5 x 10^(11) cm.(-3) whichexceeds twice of the plasm. cut-off density, suggesting that electron cyclotron heating bym.de-converted electron Bernstein waves m.y take place.

Two-dim.nsional structure of density fluctuations is exam.ned during the current jum. phase, indicating a change from.the open m.gnetic fields to the closed ones. During the sm.oth current ram.-up phase the two-dim.nsional contour of the LiI intensity shows vertically alignm.nt, consistent with the m.gnetic surfaces. At the inflection point in Ip ram.-up the LiI intensity contour becom.s flat in the observation regim. and then suddenly a steep gradient and higher intensity regim. are form.d in the vertical direction. This higher intensity corresponds to a burst of LiI waveform. According to these changes in the contour, it is found that, within ~1 m. around the burst of LiI, a low frequency coherent wave with a long wavelength rapidly grows. The relations with other signals （m.gnetic flux and m.crowave stray power） are discussed with respect to the topological change in the m.gnetic configuration and m.de conversion of the incident electrom.gnetic waves.

目的调查个旧地区居室内氡（^222Rn）、钍射气（^220Rn）及其子体水平，明确钍射气的剂量贡献。方法考虑住宅类型和地理分布因素，从个旧市郊某村选取建筑结构有代表性的50户住宅的主卧室，采用氡-钍射气鉴别探测器测量氡、钍射气浓度，用沉积率装置测量钍射气子体浓度。其中14间居室采用连续性氡测量探测器和α谱氡、钍射气鉴别探测器测量氡、钍射气浓度，空气采样滤膜结合CR-39探测器测量钍射气衰变产物浓度，碘化钠闪烁计数器测量地表γ剂量率。结果50间居室的氡浓度为32～498Bq／m.3，平均136Bq／m.3；钍射气浓度为39～7908Bq／m.3，平均3297Bq／m.3；钍射气子体浓度为2．0～23．9Bq／m.3，平均10．2Bq／m.3。钍射气子体衰变产物致居民年平均有效剂量大于氡子体衰变产物的平均年有效剂量（2．9m.v vs 1．6m.v）。结论个旧市郊部分居室室内钍射气及其子体浓度高，钍射气子体的剂量贡献要高于氡子体的剂量贡献。在个旧开展氡致肺癌危险评价研究应当考虑钍射气子体的剂量贡献。
