 Frequency-Domain Bounds for Nonnegative, Unsharply Band-Limited Functions In this paper we give a further investigation of the method introduced by the author in [1, Frequency-domain bounds for nonnegative unsharply band-limited functions] for proving bounds for functions with nonnegative Fourier transforms. We present two-sided singular value estimates for a class of convolution-product operators related to time-frequency localization. This paper presents an expansion for radial tempered distributions on ${\bf R}^n$ in terms of smooth, radial analyzing and synthesizing functions with space-frequency localization properties similar to standard wavelets. The Balian-Low theorem (BLT) is a key result in time-frequency analysis, originally stated by Balian and, independently, by Low, as: If a Gabor system $\{e^{2\pi imbt} \, g(t-na)\}_{m,n \in \mbox{\bf Z}}$ 更多
 frequence
 The results show that 10 μmol/L Lacidipine can reduce the frequence which 10 μmol/L 5-HT induced [Ca2+] spark in SFSMC of calcium over loading to 50%, and amplitude to 50% or so. The program simulation facilities, such as time-domain analysis, frequence-domain analysis, sensitivity analysis and multiple objective optimization are described. La frequence de mue decline avec la taille, de facon prononcee chez les femelles de plus de 6 ans. Cet Isopode a ete recolte sur la totalite de l'aire prospectee mais avec une frequence peu elevee: 91% des prelevements contenaient 1 a 5 specimens et un total de 140 individus ont ete recoltes. Il est postule que cette specialisation trophique pourrait expliquer certaines caracteristiques inhabituelles tels la presence d'une seule femelle adulte de Zalophora par diplopode, la faible frequence des juveniles et l'apparente absence des males. 更多
 frequency number
 On the basis of the relation, frequency number distribution function of wave group arrival time is completely equivalent to that of phase difference spectra. Intromission frequency (number of intromissions preceding ejaculation) was affected only at 10 μg/kg 8-OH-DPAT with monkeys requiring fewer intromissions to ejaculation at this dose. However, there was some indication that the effective mating frequency (number of females producing offspring sired by a given male) of major and minor males may exhibit frequency dependence. Averaged over media, callus induction frequency (number of calli per 100 anthers) was highest in cultivars Xin White and TX 403-TSB (6.7 and 3.9%, respectively). Line-intercept estimates of large wood frequency (number per 100?m of stream) were significantly correlated to the wood census counts, but the line-intercept method underestimated frequency by about 50% (P?=?0.016). 更多
 absolute frequency
 Improved absolute frequency measurement of the 115In+ 5s2 1S0-5s5p3P0 narrowline transition: Progress towards an optical frequen We report on an improved absolute frequency measurement of the 5s2 1S00-5s5p3P0 narrowline clock transition at 236.5 nm, for a single, trapped, and laser-cooled 115In ion. For absolute frequency measurement, we use an optical frequency comb locked to a cesium clock as the reference. The source generates waves with the same absolute frequency 1/15 d-1 but different wavenumber. In addition we determine the absolute frequency scale and prove the consistency of the ansatz of Sompolinsky and Zippelius χ(ω)-χ(0)α(-iω)v at and below the AT line. 更多

 Using Synoptic data for 1951—1955,a statistical investigation on theanticyclone in Eastern Asia is made.The clasification(according to path),frequency,central intencity,variation of the intensity and the velocity of the anticyclones over EasternAsia are given. 作者根据1951—1955年天气图资料,应用统计的方法来探讨东亚地区的反气旋活动。从而提供了东亚反气旋的标准分类路径、出现的频数、中心强度、强度变化及移行速度等。 Based on the 10-years surface synoptic charts (1951 to 1960), monthly frequencies of cyclones and low pressure centers passing 2.5°× 2.5°latitude-longitude grids in Eastern Asia are analized and the main tracks are studied and classified.The cyclones are most frequent in middle part of Mongolia and north-east China, and none south of 20°N. Most of the low pressures occurred south of 45°N are very weak. Spring is the season of cyclonic activity. 本文利用1951—1960年的亚洲地面天气图,分月統計东亚地区(70°E以东,55°N以南)每2.5°×2.5°經緯格內低压中心通过的頻数,繪制了頻数分布图,确定出低压移动的主要路径,此外,还繪制了冬半年和夏半年低压发生(初現)頻数分布图、頻数百分率的随緯度分布和沿120°E与110°E經线上低压中心通过頻数的各月綜合图。結果得出:1.东亚大陆中緯度西风带的低压主要出現在蒙古人民共和国中部到我国的东北地区,20°N以南不出現溫带低气压;2.45°N以南的我国大陆上低压很弱,大多数不閉合,只有在我国东部或入海后才发展;3.日本东南面海上是低压路径的集中带;4.春季低压出現最为頻繁,秋季次之,夏季我国江淮流域低压有所增多。 最后,对低压路径进行了分类,把东亚的溫带低气压划为五大类和十一亚类,并对各类低压分别作了簡要的叙述。 Based on the daily 18:00 GCT surface, charts(1955 to 1959), the frequency distribution of the front occurrence is analysed and the location of the climatic frontal zones is determined. 本文根据1955—1959年逐日02时(北京时)东亚地面天气图統計了鋒出現頻数的分布,給出1、4、7、10月东亚气候锋的位置. << 更多相关文摘
