In 1986, Pam Woodall, an editor for The Economist magazine, introduced the Big Mac Index as a fun way of demonstrating the theory of purchasing power parity.

1986年，帕姆。伍德尔，一个《经济学家》杂志的编辑，他引进了巨无霸汉堡包的一份指数，作为"购买力平价"有趣的理论依据。

Aristocracy and gentry showed so monomaniacal concerns with the parity of statue and wealth when selecting marriage partners that resulted in endogamous marriage, i. e. marrying within their own ranks. At the same time, the family formations and marital relationships in different social ranks indicated the feature above, too.

在择偶行为和择偶标准中，中上层社会的人们强调社会地位和财富的对等，乡绅婚姻的同源性则说明各社会等级基本上是实行内部通婚的，家庭的结构特征及家庭内部的两性角色之不同也体现着等级的差异。

The economist Menzie Chinn, using purchasing power parity exchange rates, reckoned the renminbi's undervaluation to be 40%. But, after the World Bank revised China's GDP in PPP terms downward by 40%, that undervaluation disappeared. Nick Lardy and Morris Goldstein suggest that the renminbi was probably undervalued only by 12-16% at the end of 2008. And Yang Yao of Beijing University has put the misalignment at less than 10%.

经济学家陈庚辛基于购买力平价的计算显示，人民币汇率被低估40%，但如果考虑世行用购买力平价对中国GDP的调整，高估的40%几乎全部抹平；拉迪和戈德斯坦的结论是人民币被低估12%~16%（截至2008年底）；北京大学姚洋的计算显示只有不到10%。

The reason is that the population of the ground state descends and the population of the first-excited state increases in the two-color coherent lase relative that in the monochromic laser and the transition channel of the electron to the even-parity continuum

氦离子在添加倍频光的双色场作用下高次谐波产生效率极大提高的原因是：倍频光极大地加快了电子电离到连续态及返回基态这一过程，使辐射出的高次谐波光子数大大增加，该初步阐释可为高次谐波真正应用到实际中提供一些理论启示。

Now spiral arms of two of the obvious opportunity not equal, so the experimental results confirm the weak interaction of parity nonconservation.

现在左右手螺旋两种情况明显地机会不相等，所以这个实验结果证实了弱相互作用中的宇称不守恒。

Since 1957 Lee's "weak interaction in the parity nonconservation" concept was experimental and that shared the Nobel Prize in Physics; its 1954 proposed standard field theory, in the 1970s developed into integration and understanding elementary particle strong and weak, and electromagnetic interactions of the three foundation are also in the statistical physics, condensed matter physics, quantum field theory, mathematical physics in a number of outstanding major contribution.

著名美籍华裔科学家、物理学大师、诺贝尔物理学奖获得者。1957年由于与李政道提出的&弱相互作用中宇称不守恒&观念被实验证明而共同获得诺贝尔物理学奖；其于1954年提出的规范场理论，则于70年代发展成为统合与了解基本粒子强、弱、电磁等三种相互作用力的基础；此外并曾在统计物理、凝聚态物理、量子场论、数学物理等领域作出多项卓越的重大贡献。

The basic principles of linear programming algorithm for the maximum likelihood decoding of LDPC codes are analyzed, and the ways to construct the codeword polytope based on the factor graph expression of parity check matrix of LDPC codes are described.

An interview guide, entitled "Maternal Perception of the Onset of Lactation", was also used to obtain milk secretion data. Results found a mean onset of lactation of 78.2±18.7 hours (range=42 to 121 hours). The prevalence of delayed lactation onset was 43.6%(n=58). Slighly over half of participants (56.9%, n=33) were primiparous. Parity, total second stage of labor duration, duration of second labor stage beyond one hour, and perinea wound pain were the most significant predictors of delayed lactation onset.

研究结果发现：(1)首次泌乳时间的平均值为78.2±18.7小时（范围42至121小时）；(2)产妇自觉延迟泌乳的发生机率为43.6%(n=58)，其中初产妇占56.9%(n=33)，经产妇占43.1%(n=25)；(3)产次、第二产程时间、第二产程时间大於一小时、第一到第三天会阴伤口疼痛分数，是延迟首次泌乳时间的重要预测因子。
