Lanthanides belong to the sixth cycle of the periodic table Ⅲ B family, are all solid metal, they are La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, holmium, erbium, thulium, ytterbium, and lutetium were 15 kinds of metals and their periphery are two layers of electronic 5d16s2, while the peripheral third layer f orbital but never zero to 14, so the external electronic structure of 4f0-145d16s2, and therefore these elements in oxidation number are to 3, very close chemical properties, extraction, when it is difficult to separate them they are mostly multi-element mineral mix, more difficult to increase refining, and their atomic number of 57-71, one by one to increase the number of protons the nucleus, and thus extranuclear electron of gravity is also growing, so that atomic radius decreases with increasing atomic number Z, which makes lanthanides contraction, ionic radius is also reduced, which also makes Zr, Hf, Nb and Ta, Mo and W, the atom and ionic radius very close to each other they also determine a similar nature, resulting in difficult separation, also the tribe Ⅷ of the fifth cycle, ruthenium, rhodium, palladium, and the sixth cycle, osmium, iridium, platinum is very similar in nature, thus The six elements, said platinum group elements.
镧系元素属于周期表第六周期中ⅢB族,全部是固体金属,它们是镧、铈、镨、钕、钷、钐、铕、钆、铽、镝、钬、铒、铥、镱和镥共十五种金属元素,它们的外围两层的电子均是5d16s2,而外围第三层的f轨道电子却从零增加到14个,所以外围电子结构为4f0-145d16s2,而使这些元素氧化数均为+3,化学性质极为接近,提炼时很难分开,它们的矿石又大多是多种元素混在一起的,更增加提纯难度,它们的原子序数为57-71,核内质子数逐个增加,因而对核外电子引力也不断增强,使原子半径随原子序数Z增加而减小,这就使镧系元素收缩、离子半径也缩小,这也使得Zr和Hf,Nb和Ta、Mo和W等原子和离子半径都很接近、也决定了它们彼此性质类似,以致难以分离、也使第Ⅷ族中第五周期的钌、铑、钯和第六周期的锇、铱、铂在性质上极为相似,因而称这六个元素为铂系元素。

An early comprehensive attempt to incorporate the Schwabe cycle into a business cycle framework was suggested by William Stanley Jevons (18351882), who early in his career was a practicing meteorologist. In JevonsInvestigations in Currency and Finance, he discussed economic fluctuations and isolated three components of economic activity: seasonal fluctuation, business cycles and trends. Jevons attempted to statistically link the business cycle with fluctuations in sunspot activity.
早期努力将施瓦布周期并入商业周期的框架由早期是实习气象学家的William Stanley Jevons (18351882)提出在他流通与金融的研究一文中,他讨论了经济波动和经济活动独立的三个内容:季节性波动商业周期和趋势他还努力统计商业周期与太阳黑子活动波动的关系另外有由Jevons的儿子H.S。

Look of your menstrual cycle is longer, if it is within 28 days of the menstrual cycle, in the next period on the 14 days before the countdown, then that is on the 21st day of ovulation is your day, can be arranged makelove in 19,21 , 23, three on the line, if you are 29 days of the cycle, that is, on the 18th day of ovulation, to such a method, not necessarily very accurate, because sometimes ovulation will be affected by many factors, such as: mood, work stress and environmental change, food and drugs, there will be advanced or delayed, so the general recommendation in the ovulation period ovulation test strip under the combination could be more accurate to seize the day of ovulation.
要看下你的月经周期是多长了,如果是28天的月经周期,在下次月经日倒数的14天前,那么也就是21号这天是你的排卵日,可安排makelove在19、21、23号,三次就行,如果你是29天的周期,就是18号的排卵日,以此种方法计算,并不一定很准确,因为排卵有时会受很多因素的影响,比如:心情、工作压力、环境改变、食用药物等,会出现提前或推后,所以一般建议在排卵期里结合下排卵试纸会能更准确的抓住排卵日。
