  1. In the lowest order, for the propagation of solitons in an inhomogeneous dusty plasma composed by two kinds of dust grains with different masses, if the interface of two kinds of dust grains in an inhomogenous dusty plasma is discontinuous, the tra nsmision and reflection waves both can be described by the kdv equation

    2在非均勻塵埃等離子體中，對于小的、但有限振幅的長波振動，孤子可用kdv方程（或kdv型方程）來描述，而且電勢孤子的傳播情況在定性上與離子等離子體中電勢孤子的傳播情況一致。
  2. It is shown by structural seismic response of four wavelets that littlewood - paley wavelet is not suitable for structural seismic response, because structural response is too small, meyer wavelet is a better wavelet for structural seismic response, for it ' s structural response is agreement with the finite element method, and also harmonic wavelet, structural response under earthquake is a little bigger than finite element method, structural response under odd exponent wavelet is also bigger than finite element method, this method is very simple by wavelet transform, wavelet transform method is different from old methods, one is with which not only knows the effects of earthquake wave detail frequency - band on structural response, but also considers earthquake wave ' s non - stationary of frequency and time - domain value, another is the second mode shape and higher mode shape response that do n ' t attenuate so fast

    通過對這四種小波的結構地震反應分析研究說明： littlewood ? paley小波不適合於用來作結構地震反應分析，因為在littlewood ? paley小波下的結構地震反應太小，不符合實際情況；用meyer小波作結構地震反應分析比較合適，和有限元法的結果比較接近；也可以用諧波小波來作結構地震反應分析，只是在諧波小波下的結果略為偏大；單邊指數小波下的結構地震反應分析比有限元法稍大一點，它通過小波變換大大簡化了結構地震反應分析。用小波變換方法來進行結構地震反應分析和以往方法不同的是：它不僅可以知道地震波的具體頻率段對結構反應的影響，而且同時考慮了地震波的幅值非平穩性以及頻率非平穩性；另外與以前方法得到的結果有差異的是，第二振型及以後的高一點的振型的反應沒有以前的方法衰減得快。
  3. To study the acoustic unsteady combustion of srm, built the acoustic model of chamber. deduced the little amplitude sound wave 3d equation, used the finite volume discrete method to simulate. got the vibration model of three kinds of chamber

    為研究固體火箭發動機聲不穩定燃燒特性，建立了燃燒室內聲學特性分析的物理數學模型，推導了小振幅聲波三維波動方程，採用有限體積離散方法進行模擬，得到圓柱型、四片翼柱彤和五片翼柱型藥柱三種燃燒室形狀聲學振動基本模態
  4. Much of his work bears on the concept of parallel universes : evaluating evidence for infinite space and cosmological inflation ; developing insights into quantum decoherence ; and studying the possibility that the amplitude of microwave background fluctuations, the dimensionality of spacetime and the fundamental laws of physics can vary from place to place

    許多他的工作都含有平行宇宙的概念：評估無限大空間與宇宙暴脹的證據，發展對量子去相干現象的洞察，以及研究諸如微波背景輻射漲落的振幅、時空的維度以及物理的基本定律可隨位置而變化的可能性。
  5. Finite amplitude wave

    有限振幅波
  6. The numbers and amplitudes of both transimtted and reflected solitons from an incident soliton are given analytically for this case. if the interface of two kinds of dust grains is continuous, neglecting the reflection, the nonlinear dust - acoustic wave can be described by a kdv - type equation in the lowest order. the amplitudes, propagating velocities of these quasi - solitons for this case are also given analytically

    無論是分界面不連續變化還是連續變化，對于小的、但有限振幅的長波振動，電勢孤子從質量小的塵埃等離子體穿過分界面進入質量大的塵埃等離子體，電勢孤子的振幅將增大，速度將變快，反之，電勢孤子從由質量大的塵埃微粒組成的塵埃等離子體穿過分界面進入由質量小的塵埃微粒組成的塵埃等離子體，電勢孤子的振幅將減小，速度將減緩。
