	an increase by natural growth or addition 同义词：accumulation,
	(geology) an increase in land resulting from alluvial deposits or waterborne sediment
	(biology) growth by addition as by the adhesion of parts or particles

	1.	This formation, called an accretion disk, may be very important in some stellar birth sequences . 这种构成物即所谓吸积盘，它在恒星诞生的某些阶段可能是非常重要的。
	2.	If accretion takes place in eccentric orbits as well, the rotation will be prograde and of the right order of magnitude . 如果吸积发生在偏心轨道，则自转将是正向的，且快慢也合适。
	3.	The model comprising accretion onto a neutron star or black hole companion must still be considered a favored hypothesis . 在中子星或黑洞伴星上发生吸积的模型，仍应看成是一个有价值的假说。
	4.	As the accretion disk feeds more mass into itself, the embryo star contracts, growing ever denser and more massive . 随着吸积盘获得越来越多的物质，胚胎恒星就不断收缩，密度和质量都变得越来越大。
	5.	Effect of ice accretion on aircraft flight performance 积冰对飞机飞行性能的影响
