  1. First, the dynamic stability of braid composite cylindrical shells with the influences of some main factors is introduced. the general governing equations for the nonlinear dynamic stability is obtained. by the hamilton principle. the creep buckling analysis of braid composite cylindrical shells under axial compression and the dynamic stability under nonconservation force are discussed as emphases. in creep buckling question, by means of theoretical analysis, the instaneous critical load and durable critical load of viscoelastic braid composite cylindrical shell under axial compression are obtained and the numerical example is given

    首先介紹了編織復合材料圓柱殼在幾種主要因素影響下的動力穩定性問題，用hamilton原理建立非線性動力穩定性問題的一般性基本方程。然後重點討論了編織復合材料圓柱殼軸壓下的蠕變屈曲問題及非保守力作用下的屈曲問題。對蠕變屈曲問題，通過理論分析來得到了編織復合材料圓柱殼的瞬時彈性臨界載荷和持久臨界載荷，給出了具體的算例。
  2. Using vogel ' s wear index as the rail side wear index, the paper analyzes the side wear variations of rail head when the parameters in the wheel / rail system vary, analyzes the influences of track irregularity on rail uneven wear on gauge corner emphatically. this paper analyzes the rail side wear dates measured by track division of shan hai guan since 1990, then gains the relationship between side wear and traffic volume and sums up the characteristics and regularities in the formation and development of side wear. in the end, some measures for regarding the side wear on curves are put forward

    從輪軌摩擦、輪軌接觸幾何關系、輪軌接觸應力和輪軌蠕滑等方面對鋼軌側面磨耗機理進行了探討，從軌道幾何參數、機車車輛運營條件等方面對鋼軌側面磨耗的影響因素進行了重點分析和總結；應用輪軌系統動力學，建立了輪軌空間耦合振動時變模型，採用vogel側磨指數作為鋼軌側磨指標，系統分析了輪軌參數變化的情況下，軌頭側面磨耗的變化規律，重點分析了軌道不平順對鋼軌不均勻側磨的影響；對山海關工務段1990年以後現場測得的曲線鋼軌側磨數據進行了分析，通過擬合得到了鋼軌側磨量與運量的關系曲線，並總結了曲線上股鋼軌側面磨耗的特徵和發生、發展規律；最後提出了一些減緩曲線鋼軌側面磨耗的措施。
  3. Preliminary research on creep and dynamic characteristics, which are two important properties of asphalt concrete cores for embankment dams, through triaxial compression creep tests and dynamic triaxial test with the aid of the viscoelastic theory and the soil dynamics theory

    本文通過三軸壓縮蠕變試驗和振動三軸試驗，藉助粘彈性理論和土動力學理論，對土石壩瀝青混凝土心墻材料的兩個重要性質? ?蠕變性能和動力特性進行了初步的研究。
  4. Independently rotating wheels do n ' t engender lognitudinal creep forces, so hunting wo n ' t occur and the stability of vehicle system is very good. but independently rotating wheels lose self - steering capability of lognitudinal creep moments, so its restoration capability and curving performance becomes worse

    因此，近年來獨立回轉車輪日益受到重視，與傳統輪對相比，獨立回轉車輪不存在縱向蠕滑力產生的偏轉力矩，因而不產生蛇行運動，對提高穩定性有好處。
  5. If tapeworm larvae live in the brain, they cause increased pressure in the head, headache, nausea, vomiting, unconsciousness, blurred vision, and epilepsy. more severely, they can even cause hemiplegia partial paralysis, paraplegia paralysis of the lower body, aphasia inability to communicate and mental problems. if they live in the eyes, vision is affected, very often the movement of worms can be seen, and in severe cases, loss of sight can occur
