摘要：

对59个类星体中的57个类星体的光学连续谱进行自相关分析，发现其结构在544 +- 5.2天的适当时滞下，标准差为77光日。在Elvis（2000）[1]提出的椭圆外流风的混响背景下进行解释，这意味着在544 +- 5.2光日的类星体中风的近似特征尺寸尺度。发现这些反射流出表面的内部结构变量为11.87度± 0.40度，标准差为2.03度。

英文摘要：

Autocorrelation analyses of the optical continua of 57 of the 59 MACHO quasars reveal structure at proper time lags of 544 +- 5.2 days with a standard deviation of 77 light days. Interpreted in the context of reverberation from elliptical outflow winds as proposed by Elvis (2000) [1], this implies an approximate characteristic size scale for winds in the MACHO quasars of 544 +- 5.2 light days. The internal structure variable of these reflecting outflow surfaces is found to be 11.87 degrees +- 0.40 degrees with a standard deviation of 2.03 degrees.
