littlewood meaning in English
利特尔伍德
Examples
- Property of hardy - littlewood maximal function on sl
极大函数的性质 - Weighted boundedness for multilinear littlewood - paley operators on some block - hardy spaces
空间上的加权有界性 - So the result is more accurate than old methods . the result of structural energy response based on wavelet provides a practicable method for structure design and design energy dissipation system in structure , this chapter ' s analysis and contrast tell us littlewood - paley wavelet is not suitable for analyzing energy of earthquake ground motion and structural energy response . on the purpose of calculating energy , meyer wavelet must be modified so that its frequency integral is a constant , the result of energy by modified meyer wavelet and harmonic wavelet is practicable , only the later is bigger but in the same energy level
通过三种小波基( littlewood ? paley小波、 meyer小波、谐波小波)下的地震地面运动能量分析以及结构地震能量反应分析说明：直接通过加速度记录可以求得地震动能量，由于小波系数中同时含有时域和频域的能量，由此得出的能量比以往的方法更准确；在此基础上求得了结构的能量反应时程，为结构设计及结构中设计耗能体系提供了具体的方法；通过这一章对比分析得出， littlewood ? paley小波不适合于作地震动能量分析和结构能量反应分析。 - Based upon the theories of the communicative competence by hymes , widdowson , canale and sivignon etc . and the theory about class teaching by harmer and littlewood , the present thesis aims at the improvement of the students " communicative competence in efl class teaching , attempting to find the significant methods to make efl class teaching more effective
以hymes ， widdowson ， canale和sivignon等关于交际能力的理论及harmer ， littlewood等关于课堂教学的过程的理论为基础，本文致力于研究在英语课堂教学中如何提高学生的交际能力，致力于寻找在英语课堂教学中提高学生交际能力的有效方法。 - 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
通过对这四种小波的结构地震反应分析研究说明： littlewood ? paley小波不适合于用来作结构地震反应分析，因为在littlewood ? paley小波下的结构地震反应太小，不符合实际情况；用meyer小波作结构地震反应分析比较合适，和有限元法的结果比较接近；也可以用谐波小波来作结构地震反应分析，只是在谐波小波下的结果略为偏大；单边指数小波下的结构地震反应分析比有限元法稍大一点，它通过小波变换大大简化了结构地震反应分析。用小波变换方法来进行结构地震反应分析和以往方法不同的是：它不仅可以知道地震波的具体频率段对结构反应的影响，而且同时考虑了地震波的幅值非平稳性以及频率非平稳性；另外与以前方法得到的结果有差异的是，第二振型及以后的高一点的振型的反应没有以前的方法衰减得快。
