Collisonal quantum interference ( cqi ) was observed in the intramolecular rotational energy transfer in the experiment of the static cell, and the integral interference angles were measured. to observe more precise information, the experiment in the molecular beam should be taken, from which the differential interference angle can be obtained precisely. in this paper, the theoretical model of cqi is described in an atom - diatom system in the condition of the molecular beam, based on the first - born approximation of time dependent perturbation theory, taking into accounts the anisotropic lennard - jones interaction potentials. the method of observing and measuring correctly the differential interference angle is presented. the changing tendencies of the differential interference angle with the impact parameter, velocity, and et al. are discussed
分子內部轉動傳能的靜態池實驗觀察到了碰撞量子干涉效應( cqi ) ,並且測得積分干涉角,為了獲得更加精確的分子內部轉動傳能的碰撞量子干涉效應信息,實驗就必須要採用分子束實驗進行.本文理論上採用各項異性相互作用勢,應用含時微擾理論的一級波恩近似,假想在分子束實驗的條件下,建立在原子-雙原子分子體系中碰撞量子干涉的理論模型.理論上推導出微分干涉角具體表達式,通過計算定性地討論了微分干涉角隨著碰撞參數、速率等的變化趨勢,同時初步探討了實驗的正確觀測途徑,得出了採用分子束進行實驗觀測的實驗方法,為進一步進行分子束實驗提供了理論基礎,對實驗的進行起到了一定的借鑒作用The cause of shipping must have a flourish development with the access to world trade organization and further reformation of economy system of our country. it is imperious need to understand the hydrodynamic forces acted on ship hull while the amount of ships in the sea - routes is increasing. these forces, especially the changing tendency of hydrodynamics when the two ships are meeting or a ship is passing a pier are of great importance to avoid the shipwrecks such as ship collision
隨著我國加入wto以及經濟體制改革的深入進行,航運事業必然會得到蓬勃發展,而面對航道中日益增多的船舶,人類迫切需要了解船體上所受到的水動力情況,尤其是船體通過橋墩、兩船相遇時的干擾水動力變化趨勢,這些對避免船舶碰撞等海難事故的發生具有重要意義。They "bump into" or interfere with each other and gradually spread apart.
它們彼此「碰撞」或相互干擾,從而逐漸分散。We presented the theoretical model of collisional quantum interference on rotational energy transfer in atom - diatom system, using the theories of time dependent born approximation and quantum inelastic scattering, and taking into account the long - range interaction potentials. the key factors in the determination of the differential and integral interference angles are obtained. co a1 ( v = 0 ) ~ e3 - ( v = l ) system in collision with he is calculated, the calculated values are consistent with the experimental results, but for the partners being ne and ar, the calculated values are not so good
首次得到了從理論中計算干涉相位角的方法,得出了干涉相位角和實驗條件中各相關量的關系,並計算了coa ~ 1 ( v = 0 ) e ~ 3 ~ - ( v = 1 )和he碰撞誘導轉動能量傳遞過程中量子干涉效應的實驗,計算結果和實驗符合的很好,但是對于碰撞伴是ne和ar的實驗,計算結果不是很好,原因是隨著碰撞伴質量和極化率的增大,相互作用勢更強,應該考慮短程相互作用勢的貢獻。The intersecting and touching relationship of the assembly parts are distinguished
