摘要
我们利用2007年由Y.T. Lee微波背景各向异性阵列(AMiBA)在94 GHz对六个星系团A1689、A1995、A2142、A2163、A2261和A2390的观测数据，研究了星系团的X射线性质与热苏尼亚耶夫-泽尔多维奇效应(SZE)性质之间的标度关系。这些标度关系将积分康普顿y参数Y_{2500}与X射线推导的气体温度T_e、总质量M_{2500}以及r_{2500}内的辐射光度L_X联系起来。我们的幂律指数和归一化结果均与自相似模型及文献中的其他研究一致，但Y_{2500}-L_X关系除外，对此给出了物理解释，尽管可能仍需进一步研究。我们的结果不仅为AMiBA项目提供了信心，也支持了我们对星系团的理解。
