The famous connoisseur and collector liang qingbiao 1620 - 1690 , also known as jiaolin of the qing dynasty 1644 - 1911 used to stamp a square seal bearing four incised characters " endorsed by jiaolin " fig . 2 on the paintings he had viewed and collected as a kind of certificate of quality . this seal impression can be found on 梁氏曾钤此印于鉴藏过的无数名迹上，而虚白藏品陈淳1483 - 1544花卉图卷上亦钤有同一方印图3 ，由此可推断此画曾被梁氏鉴藏。
The pn and don were 32 % and 40 % in autumn , 31 % and 39 % in spring 1998 , respectively . pn and pp in autumn shows strong vertical gradation in autumn other than spring , and other nutrient species shows relatively uniformity in vertical scale 由于秋季浮游植物优势种为硅藻且其生物量和初级生产力均高于春季，春季优势种则为硅藻和甲藻，结合调查海域叶绿素与化学要素间的相关程度，可推断秋季正处于浮游植物生长的发展阶段，而春季正处于浮游植物生长的衰减阶段。
For example , if there is a planet orbiting around the neutron star , it will wobble a little and the pulses will come a little early or late . we can then deduce the mass and the radius of the orbit of the planet from the arrival time of the pulses . this is how the first extrasolar planet is discovered 例如假若有一颗行星围绕一颗中子星运行，它会令中子星出现摇动，引致脉冲的间隔变长或短，由此我们根据脉冲周期的变化，可推断出行星的质量和轨道半径，这亦是天文学家找出第一颗地外行星时所用的方法。

Appling the theory of industry economics , the article analyses the supervision market , deduces that the concentrate rate of supervision industry is lower in our country , by the concentration rate of supervision industry : cr8 = 8 . 6 % . the supervision market is typical no - concentration competition market 本文应用产业经济学的理论对监理市场进行分析，由监理行业的行业集中度cr _ 8 = 8 . 6 ，可推断我国监理行业的行业集中度较低，监理市场是典型的非集中竞争型市场。
