In order to proof the program ' s effectiveness, we made some experiments on ly - 12a1 by shpb. in addition, based on the pochhammer - chree ' s theoretical solution about the stress wave propagation in infinite cylindrical bar, a numerical approach for analyzing dispersion in shpb experiments is developed
由於應力波在桿中傳播時存在彌散效應,在hopkinson桿實驗中,採用桿中某處的應變來代替桿與試件接觸端面處的應變,這必然會因為應力波的彌散效應給實驗結果帶來偏差。The amplitude fluctuation and according system performance degradation induced by xpm is also studied through numerical simulation. the timing jitter caused by xpm can also have great impact on system performance. by employing lagrangian variational method and statistical method, the timing jitter caused by xpm in strong dispersion managed rz systems is studied in chapter 3
通過模擬也研究了波分復用系統中由於交叉相位調制效應引起的幅度抖動從而導致系統性能的惡化;交叉相位調制引起的時間抖動對系統性能也有較大影響,利用拉格朗日變分方法和統計分析的方法,第三章討論了強色散管理歸零碼系統中交叉相位調制引起的時間抖動。Nanoparticles show significant quantum - size effect ( such as energy band discreteness, band gap broadening, blue shift in spectra etc. ) as sizes of particles are smaller than bohr radis of exciton of bulk material with same composition ( for example, cds ’ s bohr radium is 6nm )
當納米粒子的尺寸小於其塊狀材料的激子波爾半徑時(如cds的激子波爾半徑為6nm ) ,能夠表現出明顯的量子尺寸效應(如能帶離散,禁帶變寬,光譜藍移等) 。We consider there are two kinds of mechanism causing the attenuation of sound in grain. one kind of mechanism regards the grain as quasi - porous media. it was the viscous resistance and heat conduction in the narrow passageways between the grain kernels that convert the sound energy into heat energy and lose it
首次建立了準多孔介質的概念,可將堆積的糧食看作準多孔介質(顆粒介質) ,透入糧食內部的聲波在孔隙中傳播時,由於粘滯性和導熱性的效應,把聲能逐漸變成熱能耗散。Furthermore using the variation principle in the elasticity, the wave - motion equation is derived in the finite deformation elastic thin rod with viscous and transverse inertia effects, and the characteristic curves and their characteristic relations are obtained by characteristic line method, and the influence of viscous and geometrical - dispersive effects on the propagation of wave is analyzed
再利用彈性力學中的變分原理,導出了同時計及粘性和橫向慣性效應時的彈性細桿的幾何非線性波的波動方程,用特徵線法得到它的特徵線和特徵線上的相容關系,分析了粘性耗散和幾何彌散效應對波的傳播速度的影響。分享友人
