  1. In this paper, high - order accurate weighted essentially non - oscillatory ( weno ) schemes are investigated and their applications in hyperbolic conservation laws are discussed. based on this, a new weno difference scheme which based on dispersion - relation - preserving relation is developed, and representative test cases with this scheme for computational aeroacoustics ( caa ) problems has been implemented and compared in order to test capability of wave capturing ; in addition, weno schemes generally do not converge at high order in the presence of contact discontinuity of euler equations, so a conservative front tracking technique coupling weno schemes and level set method to simulate the translating density profile is presented here, and numerical simulation with this technique for representative test case has been implemented and results show the desired accuracy

    通過對比有限元計算結果和試驗數據，分析得出塑料土工格柵筋材的最大動拉應力的分佈與靜拉應力的分佈沿筋材的埋深大致相同，只是應力的值大小不同；地震作用下土筋間的動似摩擦系數是隨地震加速度的增加而減小；模型沿墻高方向的加速度響應等。接著，根據模型動力有限元時程分析結果和模型試驗數據的比較分析，得出由土體單元、接觸單元和筋材單元組合的塑料土工格柵加筋土非線性動力有限元分析模式的合理性。
  3. The continual circulation of avian influenza in birds and the close proximity of birds to human beings increase the chance of an unprotected individual being exposed to an infectious and potentially deadly agent. when people are concurrently infected with human and avian influenza virus strains, they may serve as the mixing vessel for the emergence of a novel subtype of virus having sufficient human influenza genes to facilitate transmission from person to person

    禽流感在鳥類中持續散播，加上鳥類與人類的活動范圍接近，令人類在無保護的情形下接觸可致命傳染媒介的機會大增若病者同時受人類流感病毒及禽流感病毒感染，就有可能成為病毒的混合爐，並由此產生具有足夠人類流感基因易於在人與人之間傳播的新品種病毒。
  4. On the basic of a great of literature reading and research on safety of side impact of the car, according to requirement of ece r95, applied madymo6. 2. 1 software, established simulation model of side impact of the car, researched the relationship between side rigidity of the car and passenger injury in side impact, which showed that during first impact the bigger side rigidity was, the more advantaged protection for the car and passenger in a definite range, and which drew a conclusion that the most serious part of passenger injury was pelvis during first impact. then detailed the substructure model by defining bodies, joints, contact types and contact characteristic, researched some improvement approach for side safety of the car, and then analyses a particular case, that was to say to fix vehicle door bar fender on between inner and outer plate of the vehicle door, analyzed the influence of passenger injury when the bar fender was fixed on different position, the result showed that the passenger injury was less when the bar fender was fixed on the height of vehicle door decorate bar. finally, a set of tests were performed, contrasting the simulation result with the test, analyzed the influence of the side rigidity of the car to passenger injury, which showed the test

    本文在對汽車的側面碰撞安全性進行大量文獻閱讀和研究的基礎上，按照歐洲ecer95側面碰撞乘員保護法規的要求，應用多剛體動力學軟體madymo6 . 2 . 1 ，建立了汽車的側面碰撞模擬模型，研究了汽車的側面剛性對乘員損傷的影響，結果表明在「一次碰撞」中，在一定范圍內汽車側面剛性越大，越有利於汽車和乘員的保護，同時得出結論，即在「一次碰撞」過程中人體損傷最嚴重的部位是骨盆;然後通過定義各剛體、鉸鏈、接觸類型以及接觸特性，對該模型進行子結構細化工作，研究了加強汽車側面安全性的若干改進措施，並進行了一個特例分析，即在此模型的車門內外板之間安裝了車門防撞桿，分析了當車門防撞桿安裝在不同位置時對乘員損傷的影響，結果表明防撞桿位於車門裝飾條的高度時，對乘員的損傷較小;最後進行了一組側面碰撞試驗，通過試驗和模擬結果的對比，分析汽車的側面剛性對乘員損傷的影響，表明試驗和模擬結果是一致的，從而證明了模擬模型的有效性以及模擬結果的正確性。
  5. The characteristics of wheel - rail rolling contact fatigue and causes of induced fatigue were reviewed

    輪軌經過長時間滾動接觸會導致軌面剝落，產生疲勞。
  6. The fem results indicated that as to the rough surfaces in sliding contact, the value of the contact pressure was very high which coursed a high value of the heat flow rate, meanwhile the sliding time was not enough for the frictional heat to transfer, thus the highest value of the body temperature occurred just on the sliding surfaces, which possessed a sharp thermal gradient in direction perpendicular to the sliding surface. so the great thermal stress was caused just by the sharp gradient and the thermal elastic distortion with which the contact pressure changed occurred simultaneously, thus this change of the contact pressure would affect the temperature distribution in return

    對于相對滑動的粗糙表面，因實際接觸面積小而導致接觸壓力很大，這樣使得熱流密度會很大，同時由於滑動時間很短，熱來不及傳導，最高溫度發生在摩擦表面，在垂直於摩擦面的方向有很大的溫度梯度，使得熱應力很大，且最大應力發生在表面，同時產生熱彈性變形，這種變形使得接觸區域內的壓力分佈發生變化，這種變化又反過來影響了接觸區域的溫度分佈。
  7. Experts also fear the close contact between humans and wild animals in such markets could help unknown viruses jump the species barrier and spark deadly epidemics, such as the sars outbreak earlier this year
