By cascading a delay interferometer as a comb filter with a tunable bandpass filter,and employing a saturable absorber formed by a unpumped polarization-maintaining EDF to select the single-longitudinal-mode of the laser, a stable wavelength-tunabledual-wavelength single-longitudinal-mode fiber laser is demonstrated.

4将梳状滤波的延迟干涉仪与可调带通滤波器进行级联，用未泵浦的保偏掺铒光纤饱和吸收体进行单纵模滤波，获得了波长可调的双波长单纵模掺铒光纤环形激光器。

The function of 3dB fiber loop mirror in fine wavelength partition is studied. With this theory, a novel narrow linear band, dual-wavelength switchable Er-doped fiber laser is realized.2. An unpumped Er-doped fiber and broadband fiber Bragg grating with high reflectivity is served as an auto-tracking filter, where the space hole-burning effect appears when the laser signal travels and forms standing wave, thus the generation of multi-longitudinal-mode is suppressed. Then the high birefringence fiber loop mirror is introduced to act as comb-liked wavelength filter.

主要包括：1、发现3dB光纤环镜的精细波长分割作用，并利用这种分割机制，研制成功一种窄线宽、双波长可转换的掺铒光纤激光器。2、利用未受泵浦的掺铒光纤以及宽带高反射率的光纤布喇格光栅做自动跟踪滤波器，当穿行其中的激光信号构成驻波时，出现了空间烧孔效应，从而抑制了多纵模的产生，引入高双折射光纤环镜做梳状波长滤波器。

The Sydney Symphony ' s performance in Hong Kong is part of an Asian tour. In the concert, the orchestra will perform Prokofiev ' s 《 Symphony No. 5 in B-flat, Op.100 》, Rachmaninov ' s 《 Vocalise 》 and also Rachmaninov ' s 《 Piano Concerto No.2 in C Minor, Op.18 》 with the Hong Kong young pianist Rachel Cheung.

香港的演出是悉尼交响乐团亚洲巡回演出的其中一站，今次音乐会乐团演出浦罗歌菲夫作品《降 B 大调第五交响曲，作品一百》，拉赫曼尼诺夫的《声乐练习曲》，以及与香港年轻钢琴家张纬晴一同演出拉赫曼尼诺夫《 C 小调第二钢琴协奏曲，作品十八》。

Mr Kim claimed that his previous launch—of a Taepodong missile over Japan in 1998—put into orbit a satellite which then warbled patriotic tunes back from space.

金正日宣称其先前的那次试射——1998年发射了一颗越过日本上空的大浦洞级导弹——将一颗卫星送进了预定轨道，从卫星上传回了振奋人心的爱国歌曲。

Results show that the water environment of the upper Huangpu River is affected integratedly by land use and flow from the upper reaches; river water quality is negatively related to proportion of industrial land in the sample zones; and the water quality at the water catchment near the Songpu Bridge is closely related to the water quality of the flow coming down from the upper streams, and driving forces of change in land use, such as development of the industry and population density in the waterhead region.

结果表明，黄浦江上游水环境质量受到土地利用格局及上游来水的综合影响，各样带工业用地比例与水质改善指数呈极显著负相关(P.01)，松浦大桥取水口水质与上游来水水质以及水源地当地的工业发展、人口密度等土地利用变化驱动力具有很好的关联性。

They get all their chawing by borrowing; they say to a fellow,"I wisht you'd len' me a chaw, Jack, I jist this minute give Ben Thompson the last chaw I had"-- which is a lie pretty much everytime; it don't fool nobody but a stranger; but Jack ain't no stranger, so he says: YOU give him a chaw, did you?

他们嚼的烟都是借来的——他们对一个家伙说：&杰克，借口烟嚼嚼，怎么样。我刚把我最后一口烟给了朋·汤浦逊&——而这是谎话。往往每回都如此，除非是生人，这骗不了谁，而杰克可并非生人，他就说：你给过他一口烟，真是这样么？
