希尔加德(***)是美国著名的心理学家,他通过对催眠的研究,提出一种关于意识的新观点。希尔加德认为在人的中枢神经系统中存在多个控制系统。例如,大脑的左半球和右半球就是两个功能不尽相同的控制系统。此外,还发现在大脑里有一个控制系统能保持人对环境中事件的警觉,而另一个系统则能产生梦。在任何一个特定的时刻中,总是有一个系统对于另一个系统处于主导地位。当我们清醒时,警觉的系统占主导地位,而在睡眠中,梦的系统占主导地位。然而即使

International Journal of Astronomy and Astrophysics 2021年第2期11卷 151-174页

作者： Denis Leahy Cole morgan Josep Postma megan Buick Department of Physics and Astronomy University of Calgary Calgary Canada

AstroSat has surveyed m31 with the UVIT telescope from 2017 to 2019. The central bulge of m31 was observed in 2750 - 2850 A, 2000 - 2400 A, 1600 - 1850 A, 1450 - 1750 A, and 1200 - 1800 A filters. A radial profile analysis, averaged along elliptical contours which approximate the bulge shape, was carried out in each filter. The profiles follow a Sersic function with an excess for the inner ~8" in all filters, or can be fitted with two Sersic functions (including the excess). The ultraviolet colours of the bulge are found to change systematically with radius, with the center of the bulge bluer (hotter). We fit the UVIT spectral energy distributions (SEDs) for the whole bulge and for 10 elliptical annuli with single stellar population (SSP) models. A combination of two SSPs fits the UVIT SEDs much better than one SSP, and three SSPs fit the data best. The properties of the three SSPs are age, metallicity (m>Zm>) and mass of each SSP. The best fit model is a dominant old, metal-poor (1010 yr, mg src="Edit_***" alt="" />, with mg src="Edit_***" alt="" /> the solar metallicity) population plus a 15% contribution from an intermediate (109.5 yr, ) population plus a small contribution (~2%) from a young high-metallicity (108.5 yr, mg src="Edit_***" alt="" />) population. The results are consistent with previous studies of m31 in optical: both reveal an active merger history for m31.

一直以来，有许多人认为控制气候变化如全球变暖必须作以下三方面的工作：第一，在做出控制气候变化行动之前，我们首先应该进行全面的研究，消除一切不可确定性；第二，过多排放二氧化碳的国家都必须控制二氧化碳的排放；第三，这些国家都应该确定一个减少二氧化碳排放的目标。但是，我认为这三个想法都是错误的，同样错误的还有，通常情况下，解决这个问题的传统途径是：

虽然1920年就已采用静注巴比妥类药物施行麻醉,但是直到1935年硫喷妥钠问世以后,静脉麻醉才被逐渐推广。在这以前,全身麻醉—催眠、镇痛和肌松基本均采用单纯的吸入麻醉剂如乙醚或氯仿。这完全可以用现代的静脉麻醉剂代替。由于当时对硫喷妥钠认识不足,特别当大剂量单独应用时,对心血管和呼吸的抑制作用曾导致了灾难性的后果。以致被称为“理想的安死术”。此后,由于经验的不断积累,硫喷妥钠
