Mr greenspan said he would expect “ as a minimum , large single - digit ” percentage declines in us house prices from peak to trough and added that he would not be surprised if the fall was “ in double digits ” 格林斯潘称，他预计美国房价从峰值水平到最低水平“至少会出现较大个位数”的跌幅，并补充称，如果跌幅“达到两位数” ，他不会感到惊讶。
The paper has introduced a new means on the automatic focus that take advantage of the video peak to change the position of the focusing lens to achieve a clear picture 摘要介绍了一种新型的自动调焦的方法，它利用电视跟踪系统视频信号的峰值变化控制调焦镜组，来调整由于目标距离、温度等变化引起的成像焦面变化，得到清晰图像，完成电视自动调焦。
Milan lead serie a after a flawless february and , after roy carroll s goalkeeping error at old trafford 13 days ago , ferguson believes his players will have to touch their most exhilarating peaks to stand any chance of progressing to the quarter finals 即使在客场，他们也能1 : 0击败不可一世的曼联。要想战胜这样的球队，对于曼联来讲无异于攀登一座难以逾越的高山。
Cool ( heat ) storage is used extensively , not only can adjust supply and need of energy , shift electric loads from on - peak to off - peak , balance energy system , but also can reduce energy consumption , realize high - efficient and logical utilization of energy 蓄冷(热)应用非常广泛，不仅可以调节能量供需，移峰填谷，平衡能量系统，而且可以降低能耗，实现能量的高效合理利用。
Fft is applied to data and spectra peak search is done , then using the data near the spectra peaks to compute two 4th - order cumulants matrix to form rotational invariance matrix pencil which the esprit algorithm can be applied to 对采样数据进行fft和谱峰搜索，截取谱峰附近数据构造一路信号的四阶累积量矩阵和二路信号的互四阶累积量矩阵，构成了一对esprit算法所需要的旋转不变矩阵束。
They have undergone systematic and intensive trainings before the event , which enabled them to beat their counterparts from 12 other companies with perseverance and esprit de corps , completing the 50 km hong kong trail from the peak to big wave bay in the best of time 赞助，该公司更派出其员工联同富城集团100名义工前往各物业的长者住屋派发福袋，并与各长者玩游戏及唱歌，共同渡过温情洋溢的时光。
The results showed that the magnitude and shape of mfl vary with the change of wire rope tension . with the stress increment , the peak to peak values of broken wires reduce obviously and the total strength of mfl signal becomes weak and the ripple of mfl signal curve appears 试验研究发现，漏磁密度的大小及形态都随钢丝绳张力的变化而改变，随张力增加，断丝峰峰值明显减小，漏磁信号的总体波动强度减弱，漏磁曲线上有应力波纹出现。
Under the situation of gas supply demand contradiction growing day after day , by studying the features of gas supplying delivering loads of gas pipelines and the gas price in the sichuan basin , according to the gas transmission capacity of the pipelines limited by the given gas transmission facilities , it is suggested removing the peak to fill the valley and optimal distributing the loads , which can not only improve the efficiency of gas supplying / delivering facilities , and release a part of gas supply / demand contradiction , but also improve the benefit of gas marketing 摘要在天然气供求矛盾日益加剧的情况下，通过研究四川盆地天然气管输供气负荷特征与用户用气负荷特征及气价的关系，提出在一定输气设施所确定的管输能力情况下，通过移峰填谷和择优配置负荷，既可以提高天然气管输供、用气设施效率，缓解一部分天然气供求矛盾，又可提高天然气销售效益。
The characteristics of each rainbow for an inhomogeneous particle are studied here using lorenz - mie theory . the relation of the positions of airy peaks to each order rainbow with the profile of refractive index is simulated and discussed , which is compared with the results simulated by ray tracing theory 本文还利用lorenz mie理论分析了非均匀球粒子各阶彩虹的强度和频谱分布特点，利用ifft方法重建了各阶彩虹的强度分布；分析研究了各阶彩虹的airy峰角位置与折射率分布的关系，并与非均匀粒子射线追迹理论的模拟结果进行比较。
