|
A number of q,t-analogues of this fact were conjectured in [10]; the present paper proves most of those conjectures, as well as some new identities suggested by the proof technique.
|
| 例句来源 | |
In this paper we present a technique for proving bounds of the Boas-Kac-Lukosz type for unsharply restricted functions with nonnegative Fourier transforms.
|
| 例句来源 | |
This technique gives rise to several "epsilonized" versions of the Boas-Kac-Lukosz bound (which deals with the case f(u) = 0, |u| ≥ 1).
|
| 例句来源 | |
The basic technique uses factorization of group elements and Gel'fand-Tsetlin bases to simplify the computations, and may be extended to treat the computation of Fourier transforms of finitely supported distributions on the group.
|
| 例句来源 | |
Our technique applies, in particular, to the Shannon and Journe wavelet sets.

The fiberization of affine systems via dual Gramian techniques, which was developed in previous papers of the authors, is applied here for the study of affine frames that have an affine dual system.
|
| 例句来源 | |
Gramian techniques are also used to verify whether a dual pair of affine frames is also a pair of bi-orthogonal Riesz bases.
|
| 例句来源 | |
In this article we investigate the asymptotic behavior of and using the dynamical system techniques: the pressure function and the variational principle.
|
| 例句来源 | |
As an application of these techniques, we prove that the set of MRA wavelets is arcwise connected in L2(R).

| | The present paper gives a report on a study of the life his- tory of a destructive pest, Melanauster chinensis Forster, of citrus trees in Foochow during the years 1951 and 1952. It has been found that the adults lay eggs beginning from the last part of May until the end of July. Eggs are inserted in the bark of the tree trunk about 1. 4 inches from the ground. Incubation period lasts from 9 to 14 days. After hatching the young larvae feed under the bark for three or four months. In October they bore into t... | | 星天牛为柑桔主要害虫之一,研究此种害虫者颇不乏人,但就所见文献中关于该虫习性的报道,多不足作为防治的有力参考。笔者有鉴及此,于一九五一至一九五二年在福州研究这一害虫的生活习性,尤其对于幼虫为害的隧道,有比较详细的观察。把果农钩杀幼虫这一防治方法的实践与理论相结合,初步掌握了幼虫在柑桔树干中钻蛀为害的规律,使过去所谓奥妙不可捉摸的钩杀技术得到了解析,同时也把这一技术从现有的水平提高了一步,希望可以为一般从事柑桔栽培工作者所掌握,成为简单易学的一件事。五月下旬至七月下旬均有成虫产卵,产卵位置平均离地面1.4寸,卵期九至十四天。幼虫孵化后即从产卵处蛀入,向下蛀食于表皮与木质部之间,其向下蛀食范围多在地面下五寸以内。一般在三、四个月后亦即在十月左右,以成熟或将成熟的幼虫,蛀入木质部内,作一隧道,准备过冬及化蛹。蛀入孔多在地面下—、二寸处。一般幼虫在十—、二月开始休眠越冬,历时约三、四个月,翌年三月以后又开始恢复活动。四月中旬开始化蛹,蛹期十八至二十天。成虫羽化后在蛹室内停留五至八天。自五月中旬至七月中旬都有成虫出现,迄八月中旬仍见有极少数成虫。幼虫所营隧道的形状、长短,都有一定的规律,文中有详... | | 文摘来源 | | This paper presents a method by which a complete set of static characteristics of a power tube, including that of positive grid region, can be seen all at once on the screen of a cathode ray oscilloscope. Use is made of pulse-technique and intensity modulation of a cathode ray tube. Circuits are given and explained for observing plate characteristics on the plate current-plate voltage plane as well as constant current contours on the plate voltage-grid voltage plane, the former being shown in fig. 11 and th... | | 利用脉冲技术和阴极射线管栅极调亮法,可以在示波器上描绘出整套特性曲线,特别是正栅区域的特性。这个方法对于强力管的制造厂检验所制成品是否合乎规格时会有一些帮助。 | | 文摘来源 | | Impact tests have been carried out on nodular cast iron in -the cast and forged conditions from -85℃ to 1070℃. The results indicate that nodular cast iron of predominantly ferritic matrix possesses two brittle temperature ranges (below 20℃ and between 550 and 700℃), and one comparatively more ductile range (between 850℃ and 1050℃). | | 本文描述高温冲击实验的技术,以及由-85℃至1070℃的铸态和锻造后的球墨铸铁的冲击性能。研究结果找到了基体主要为铁素体的球墨铸铁的两个变脆温度范围(-20℃以下和550℃至700℃之间)和一个比较具有韧性的温度范围(850℃与1050℃之间)。在这些温度范围内,曾考查试样的断口情况和断裂时的弯曲角度,并与其基体组织的变化相联系,进行讨论。最后,本文指出研究结果在球墨铸铁的应用上所起的作用,以及在球墨铸铁热加工时对于选择热加工温度的意义。 | | 文摘来源 | |   | | << 更多相关文摘 |
