The numerical calculating based on reynolds equation are carried out with the help of computer program built by bearing research institute of xi ' an jiaotong university. the calculating results indicated that three lubricating oil wedge bearing with an end - to - end through gap between the horizontal combine surfaces will not be unsteady factor when the bearing load no change. but the horizontal oil film rigidity will reduce and the working position of axle journal in the bearing will change
論文利用雷諾方程對# 5軸承的三油楔水平中分軸承進行了數值計算，計算結果表明，當三油楔軸承水平中分面有貫通的縫隙而軸承的載荷不變時，三油楔軸承不會失穩，但會減小水平方向的油膜剛度，改變軸頸在軸瓦中的工作位置。 -
In the third chapter, we will study the existence and uniqueness of the classical global solution and generalized global solution to the periodic boundary value problem and the cauchy problem for this kind of equation. in the second chapter, we study the following nonlinear wave equation of higher order : with the initial boundary value conditions or with where a1, a2, a3 > 0 are constants, ( s ), f ( s0, s1, s2 s3, s4 ) are given nonlin - ear functions, u0 ( x ) and, u1 ( x ) are given initial functions. for this purpose, by green ' s function of a boundary value problem for a fourth order ordinary differential equation we first reduce the problem ( 1 ) - ( 3 ) to an equivalent intergral equation, then making use of the contraction mapping principle we prove the existence and uniqueness of the local classical solution for the intergral equation
本文分三章，第一章為引言；第二章研究一類非線性高階波動方程的初邊值問題的整體古典解的存在性和唯一性，以及古典解的爆破；第三章研究此方程的周期邊界問題和cauchy問題的整體廣義解和整體古典解的存在性和唯一性，具體情況如下：在第二章中，我們研究一類非線性高階波動方程的如下初邊值問題：或或其中a _ 1 ， a _ 2 ， a _ 3 0為常數， （ s ） ， （ s _ 0 ， s _ 1 ， s _ 2 ， s _ 3 ， s _ 4 ， ）為已知的非線性函數， u _ 0 （ x ） ， u _ 1 ， （ x ）為已知的初始函數，為此，我們先用四階常微分方程邊值問題的green函數把上述問題轉化為等價的積分方程，然後利用壓縮映射原理證明此積分方程局部古典解的存在性和唯一性，又用解的延拓法證明上述問題整體古典解的存在性和唯一性，主要結果有：定理1設u _ 0 （ x ） ， u _ 1 （ x ） c ~ 4 [ 0 ， 1 ]且滿足邊界條件（ 2 ） ，若以下條件滿足：其中a ， b月0為常數， w -
Meanwhile, the key research topics are focused on how to reduce the differential settlement between the main tall building and the anex on soft ground, where to set the post - cast strip, and what cause the smart change of the internal force of plate under the core canister of tall building. an experiential equation for estimating the maximum moment of plate is advanced. a method for calculating the range and the thickness of the local enganced plate and another experiential equatio n for estimating the increment of maximum moment of the local plate are also suggested
同時著重就軟弱地基中減小高層建築主裙房之間沉降差異的措施、施工后澆帶的設置位置，以及高層建築核心簡體下筏板內力變化劇烈等問題展開了分析，提出了筏板最大彎矩估算值的經驗公式，獲得了簡體下局部筏板加厚處加厚范圍及加厚厚度的取值方法及加厚處最大彎距增幅估算值的經驗公式，為今後設計同一類型高層建築提供一些借鑒。 -
