考虑剪应变的弹性薄壁杆件的振动理论

<正> 对于开口截面彈性薄壁杆件的振动問題,符拉索夫在1940年提出的理論,是基于下列两个基本假設:(1)截面具有剛硬不可变形的周綫;(2)中曲面无剪应变。其后,有些学者也曾提出过相同的理論(例如.R.海里格).由于忽略了中曲面的剪应变,我們可以估計得到,符拉索夫的理論只适用于研究低频率的固有振动和強迫振动,而不适用于研究高频瘁的振动。由于行动載荷和冲击载荷必然引起各个固有频率的振动,因此符拉索夫的理論也不适用于研究这些載荷作用下的振动問題。为了要更好地研究这些問題,必須要考慮剪应变的影响。

A new method of studying the dynamical behavior of the sine-gordon equation

We try to connect the theory of infinite dimensional dynamical systems and nonlinear dynamical methods. The sine-Gordon equation is used to illustrate our method of discussing the dynamical behaviour of infinite dimensional systems. The results agree with those of Bishop and Flesch [SLAM J. Math. Anal. 21 (1990) 1511].

[Discurso do Deputado Odacir Klein : Sessão Conjunta do Congresso Nacional de 21 de junho de 1979]

Em aparte a pronunciamento em que o Deputado Heitor de Alencar Furtado discute a PEC 2/79, sustenta que a falta de uma representação política que fiscalize os atos do Governo do Distrito Federal enseja ocorrências como a do emprego de vultosos recursos na construção de um parque recreativo, apesar da carência total nos setores de saúde e educação. Observa que a Comissão do Distrito Federal do Senado, o único órgão fiscalizador dos atos do Governo do Distrito Federal, não é composta de representantes eleitos pelos habitantes da Capital da República.

[Discurso do Deputado João Herculino : Sessão da Câmara dos Deputados de 30 de julho de 1964]

Denúncia de conspiração que se vem desenvolvendo no seio do próprio Governo, visando à derrocada da administração do Presidente Castelo Branco. Trama que neste sentido vem sendo preparada pelos Ministros Otávio Bulhões, Roberto Campos e Arnaldo Sussekind, e pelo Diretor do DASp. Protesto contra o fato de o Ministro de Trabalho vir desprezando os acordos salariais firmados no ano findo (aeroviário e marítimos). Críticas aqueles que vêm atuando no sentido de impedir a consolidação de Brasília como Capital Federal. Referências ao retorno de seções do Banco do Brasil e da CONTEL para a Guanabara.

钝锥高超声速边界层来流感受性数值研究

应用作者所建立的高精度非定常激波装配法,数值模拟了高超声速条件下,钝锥绕流快声波来流扰动非定常流场,研究了钝锥超声速边界层对来流扰动感受性特征,研究表明,在各种来流扰动的条件下,钝锥边界层感受到的主要是声波扰动;钝锥边界层内扰动模态,在头部附近是第一模态,向下游依次转换为第二模态、第三模态;另外随钝度减小,边界层内扰动模态的振幅增大,但有一临界值,超过临界后反而减小,并且由于曲率间断的影响,模态振幅随钝度的变化不再是单调变化的.

非传播孤立波及其相互作用的数值模拟

通过数值求解由Miles导出的目前公认的非传播孤立波的控制方程——一个带复共轭项的非线性立方Schr〖AKo¨〗dinger方程,对非传播孤立波进行研究.讨论了Miles方程中的线性阻尼系数α的值,模拟了两个非传播孤立波的相互作用,数值模拟表明,两个波的作用模式依赖于系统的参数,对不同的初始扰动及其演化的计算表明,只有适当的初始扰动才能形成单个稳定的非传播孤立波,否则扰动可能消失或发展成多个孤立波.

Selection of a management option is dependent upon which issues are perceived to be true problems. Management options are presented along with their effectiveness in dealing with issues previously described.(31 page document)

圆柱形容器中竖直激励表面波的毛细影响

在竖直振动的圆柱形容器中，利用理想流体中两时间尺度奇摄动展开法，研究了包括表面张力影响的自由面单一表面驻波的运动．通过求解势流方程，获得了一个包含三阶非线性项、外激励及表面张力影响的非线性振幅方程．结果表明当驱动频率较低时，表面张力对表而波模式选择不重要；然而，当驱动频率较高时，表面张力的影响是不可忽略的．说明表面张力具有使得自由面返回到平衡位置的作用．另外，由于考虑了表面张力的影响，使得理论结果比无表面张力时更加接近先前的实验结果．

Interim report on the progress of an inventory of artesian wells in Florida: leading to the enforcement of sections 370.051 - 370.54, Florida statues

One of the causes of lower artesian pressure, water waste and aquifer contamination is the misuse and insufficient care of artesian wells. In 1953, Senate Bill No. 57, entitled "An Act to Protect and Control the Artesian Waters of the State" (see Appendix) became a law. This law was passed through the efforts exerted by leading members of the Senate and the House of Representatives, who understood the need for a wise and controlled expenditure of our most valuable natural resource. The State Geologist and his authorized representatives were designated by this law to enforce this conservation measure; however, no financial provision was included for the 1953-55 biennium. The proposed program of the Florida Geological Survey for this biennium did not include the funds nor provide any full-time personnel for the enforcement of this statute. As a result, little actual work was accomplished during these two years, although much time was given to planning and discussion of the problem. Realizing that this program could provide additional basic data needed in the analysis of the water-supply problem, the State Geologist sought and was granted by the 1955 Legislature adequate funds with which to activate the first phase of the enforcement of Florida Statute No. 370.051-054. Enumerated below is a summary of the progress made on this investigation as outlined previously: 1. Data have been collected on 967 wildly flowing wells in 22 counties. 2. Chloride determinations have been run on 850 of the 967 wells. 3. Of the 967 wells, 554 have chlorides in excess of the 250 ppm, the upper limit assigned by the State Board of Health for public consumption. 4. Water escapes at the rate of 37, 762 gallons per minute from these 967 wells. This amounts to 54, 377, 280 gallons per day. The investigation is incomplete at this time; therefore, no final conclusions can be reached. However, from data already collected, the following recommendations are proposed: 1. That the present inventory of wildly flowing wells be completed for the entire State. 2. That the current inventory of wildly flowing wells be expanded at the conclusion of the present inventory to include all flowing wells. 3. That a complete statewide inventory program be established and conducted in cooperation with the Ground Water Branchof the U.S. Geological Survey. 4. That the enforcement functions as set down in Sections 370.051/.054, Florida Statutes, be separated from the program to collect water-resource data and that these functions be given to the Water Resources Department, if such is created (to be recommended by the Water Resources Study Commission in a water policy law presented to the 1957 Legislature). 5. That the research phase (well inventory) of the program remain under the direction of the Florida Geological Survey. (PDF contains 204 pages.)

Record of wells in Manatee County, Florida

A detailed study of the geology and ground-water resources of Manatee County (fig. 1) was made during the period from 1950 to 1955. This report contains a table of well records that was compiled from data collected during that investigation. The well-numbering system used in the table is based on latitude and longitude.

In Situ Synthesis of Nanocrystalline Intermetallic Compound Layer During Surface Mechanical Attrition Treatment of Zirconium

The surface mechanical attrition treatment (SMAT) technique was developed to synthesize a nanocrystalline (NC) layer on the surface of metallic materials for upgrading their overall properties and performance. In this paper, by means of SMAT to a pure zirconium plate at the room temperature, repetitive multidirectional peening of steel shots (composition (wt%): 1C, 1.5Cr, base Fe) severely deformed the surface layer. A NC surface layer consisting of the intermetallic compound FeCr was fabricated on the surface of the zirconium. The microstructure characterization of the surface layer was performed by using X-ray diffraction analysis, optical microscopy, scanning and transmission electron microscopy observations. The NC surface layer was about 25 mu m thick and consisted of the intermetallic compound FeCr with an average grain size of 25 +/- 10 nm. The deformation-induced fast diffusion of Fe and Cr from the steel shots into Zr occurred during SMAT, leading to the formation of intermetallic compound. In addition, the NC surface layer exhibited an ultrahigh nanohardness of 10.2 GPa.
