Nevertheless, in these approaches the contact intethee are charactered sboly ed stiffeess k. and k. " which is not perfect and rigorous in thc vitw of solid mechanics and rather rough for the description of the behavior of the idtfores. in collbet, taken as a contact problem, the principal chatrs of the idtcthees can be reflected : ( l ) the cbntact inifore is of shear strength which implies tha a generic pair of contact points on the inidse will displace coincidentally if the tangential fbrce at this point has not reahed the 1imit resistance, else, relative s1ide betwee the points will occur along the tangental direction. ( 2 ) no matter the relative slide occurs or not, the contact bodies cannot invade each other in any wise
本論文在對這兩種方法進行認真的分析后,說明它們對不連續面的描述並不合理,也無法反映出不連續面的主要力學特性,同時指出,將帶有不連續面的巖土工程問題作為接觸問題計算更為合理,它可將不連續面受力變形的主要特點反映出來,即: ( 1 )接觸面具有相應的「抗剪強度」 ,即當接觸面上某一點處的切向應力小於該點處的抵抗強度時,點對共同變形;達到強度時,則沿切向發生相對滑動; ( 2 )在整個變形過程中,發生接觸的變形體不能相互侵入。The reactions(forces)on each sphere were equal and opposite and directed along the diameter through the point of contact.

針對彈性滾柱與剛性平面的穩態滾動接觸問題,採用已知接觸區右端點來搜索接觸區左端點以及區內粘連區、滑移區分佈的迭代搜索方法,並根據搜索得到的接觸區內分佈壓力反求出外部載荷。The 16 - node degenerated iso - parametric element is proposed for the analysis of raft foundation with mid - thick plate. the stiffness matrix of single pile among the pile group can be founded assuming the total contact between the plate and the foundation. and the results of stress and deformation of plate, the force on pile and the settlement of pile bottom can be solved after the finite element disperse for the plate and the establishment of balance equation of pile - raft interaction
在引入16節點退化等參元的中厚板筏板分析模型的基礎了,假定筏板與地基間完全接觸,建立了群樁中單樁樁身剛度矩陣,繼而對筏板進行有限元離散得到樁筏共同作用的平衡方程,從而求解筏板內力、撓度、樁頂反力、樁端沉降等一系列結果。A novel method of electrostatic suspension was developed. this article briefly discusses the basic concept, schematic setup and optronic feedback system of the electrostatic suspension. when taking an aluminum plate and a compact disc ( cd ) as the suspended objects respectively, it is measured the electrostatic forces acting on the objects under different electrode voltages and different electrode - object gaps. the experimental results show that the electrostatic forces are sufficient to levitate both of the suspended objects, namely the electrostatic suspension method is practically feasible. compared to the conventional magnetic suspension, the significant characteristic of the electrostatic suspension is that it is capable of suspending most of the conductive and / or nonconductive, magnetic and / or nonmagnetic objects. therefore, this method can be widely applied to realize the electrostatic suspension and non - contact manipulation of the precision objects
本文提出光電反饋式靜電懸浮的新方法,簡要討論靜電懸浮的原理、裝置及其光電反饋控制過程.採用鋁片和cd光盤作為懸浮體,測定了不同靜電電壓和不同懸浮間距時的靜電懸浮力,揭示了它們之間的相互關系.結果顯示這兩種懸浮體均可獲得足夠的靜電懸浮力,證明了靜電懸浮的可行性.靜電懸浮方法的顯著特點是既適用於導電體與非導電體的懸浮,又適用於磁性體與非磁性體的懸浮,克服了傳統磁懸浮技術僅適用於磁性體的局限性,可廣泛應用於精密元器件的懸浮與非接觸無損操作Based on the analysis, we gave an example to study the dynamic contact with friction of the intermittent joint, and got some essential rules : the friction coefficient could n ' t influence the distributing of dynamic stress on the contact surface, and the roading rates affected evidently on the dynamic characteristic on the contact surface. in the last part, this paper made respectively use of the time - history method and the response spectrum method to analyze the dynamic response of the rock slope on baise hydraulic power plant, and got the coincident resultant. simultaneously, the contact theory was applied to study the stability of the intermittent joints
基於上述的接觸理論和接觸分析結果,本文在最後一部分中分別利用動力時程法和反應譜法對百色水電站尾水渠的巖質邊坡進行動力響應分析,兩者計算方法得出比較一致的結果,同時採用動力摩擦接觸理論重點分析了斷層對于邊坡的穩定影響,認為斷層的存在會使得巖坡的穩定性降低,在地震等動力荷載的作用下對于斷層將發生張開、閉合和錯動現象,尤其是動力荷載和其他荷載如滲流力等的耦合作用將會對斷層產生極為不利的後果,進而影響巖坡的整體動力穩定,應該要引起足夠的重視。It sounds counter intuitive, but an important thing to remember on descends is to relax, try to be fluent with your movements, if you are relaxed, with your knees and arms bend, you help the tires stay in contact with the ground for more control of braking traction
這聽起來跟你的直覺相反,可是有個很重要的一點是下坡時記得要放鬆,試著流暢的動作,如果你放鬆騎而且彎曲你的膝蓋和手臂,輪胎會保持接觸地面讓你更好控制煞車的抓力。In contrast, taken as a contact problem, the principal characters of the interfaces can be reflected : ( 1 ) the contact interface is of shear strength which implies that a generic pair of contact points on the interface will displace coincidentally if the tangential force at this point has not reached the limit resistance, else, relative slide between the points will occur along the tangential direction. ( 2 ) no matter the relative slide occurs or not, the contact bodies cannot invade each other in any wise
同時指出,將樁土相互作用按接觸問題來處理,可以更好地反映出該接觸面的主要力學特徵,即: ( 1 )接觸面具有相應的「抗剪強度」 ,即當接觸面上的某一點處的切向應力小於該點處的抗剪強度時,該處樁土共同變形;達到其抗剪強度時,則沿切向發生滑動; ( 2 )在整個變形過程中,樁與土不能互相侵入。Though it is arguably the job of congress, not the supreme court, to worry about the competitiveness of america ' s capital markets, that was clearly on the minds of the majority of the justices, who observed that, had they favoured the investors, “ overseas firms with no other exposure to our securities laws could be deterred from doing business here. . this, in turn, may raise the cost of being a publicly traded company under our law and shift securities offerings away from domestic capital markets
雖然可以抗辯說擔心美國資本市場競爭力是國會的責任,不是最高法院的職責,且大部分大法官也是清楚地知道這點的,但是他們知道若是他們支持投資者,則「沒有其他渠道接觸本國證券法的海外公司可能會止步…而這反過來會增加公司在本國法下公開上市交易的成本而使證券發行逃離本國資本市場。 」分享友人
