7.The United Nations appealed to the people of the developed countries for aiding those of the backward countries.
联合国呼吁发达国家的人民援助落后国家的人民。
8.Erbium-doped superfluorescent fiber sources (SFS) pumped near 980nm in double-pass backward (DPB) configuration have been characterized through theoretical simulation.
理论研究了双后向结构掺铒光纤超荧光光源的特性。
9.Erbium ions concentration is obtained by the information of measured coefficients along with modeling of double-pass backward (DPB) superfluorescent fiber source (SFS).

(从窗户往里看,我们看到迈克尔站着,跟一个经历模样的人说话,那个人斜靠在椅子上,很傲慢的样子。
13.The so-called hypernormal development means the regional economy can be developed with the growth rate of more than two-figure number, and realize the newcoming advantage of the backward areas.
