Neiman Marcus's strong April marked a rebound from a 22.5% decline in the year to April 2009; the 3.2% increase in revenues reported by Saks in the first quarter followed a 32% decline in the same period a year earlier, points out Steven Dennis, an analyst at Gerson Lehrman, a research firm.

内曼马库斯四月的强劲增长标志着从2009年4月到现在高达22.5%的下跌开始触底反弹；调查公司格森莱尔曼的分析师史蒂文丹尼斯指出，萨克斯百货发布的报告显示，与去年同期下降了32%相比，今年第一季度公司收入增长了3.2%。

Compared with the composite flocculant of WuHan petrochemical factory, its capability is superior to it: the efficiency of eliminating CODCr and SS are 28.75%and 8.29% respectively higher than those by flocculant of WuHan petrochemical factory, but the cost is46.63% lower; which is also far lower than the current average cost of petrochemical industry wastewater treatment. When dealing with papermaking wastewater, it can fully meet the require that WuHan ChenMing paper industry group put forward: The efficiency of eliminating CODCr higher than 25% based on the chemical cost controlled in 0.5 Yuan/ton sewage so as to better the gas float section. Those studies preparatorily show that this composite flocculant has particular effect and obvious economic、environmental benefit in industrial effluent treatment

其在处理石化废水时性能优于青山石化厂的复合絮凝剂，CODCr和SS的去除率分别提高了28.75%和8.29%，处理成本下降了46.63%；且远低于我国目前平均2.80元/的石化废水处理成本；其在处理造纸废水时，可完全达到武汉晨鸣纸业集团所提出的：药剂成本控制在0.5元/以内、CODCr去除率在25%以上的气浮工段改进要求，初步显现出该复合絮凝剂在工业污水处理中的独特作用及明显的经济与环境效益。

To meet the needs, a novel low-noise fiber laser with compound cavity structure is designed. The stable single-mode operation is realized by using a transient self-written fiber grating, produced by the effect of saturable absorption within a section of unpumped erbium-doped fiber, as narrow band filter for mode selecting and linewidth squeezing. Through optical path modification, the spectral signal-to-noise ratio is better than 62 dB.

激光器采用复合腔结构，以掺铒光纤作为工作物质，通过在未被抽运的掺铒光纤中形成的瞬态自写入光纤光栅的窄带滤波特性进行选模和压窄线宽，产生稳定的单频激光输出；经过光路改进，激光输出光谱信噪比优于62 dB；利用光电负反馈电路，弛豫振荡峰下降了约25 dB，低频段强度噪声也大为改善，有效地抑制了光源的强度噪声。
