Abstract : the effects of young ' s modulus on the wave velocity , on the potential energy and kinetic energy in arbitrarily volume in the maocinery longitudinal and on the vibration phase among incidance ware , reflex wave and transmission wave at the boundary surface of two kinds of medium are discusseed 文摘:本文就楊氏模量在機(jī)械縱波中的波速、任意體積內(nèi)的勢能和動能及在兩種介質(zhì)界面處入射波、反射波、透射波的振動周相關(guān)系中的作用作了闡述。
At the present time , the first choice driver of icf is the laser . the basic requirements to the kdp crystal optics of icf solid laser driver are : high accuracy face shape quality ( transmission wave front / 6 pv ) , high laser damage threshold value ( 15j / cm2 ) , good surface roughness ( 5nm ) 慣性約束聚變固體激光驅(qū)動器對kdp晶體光學(xué)零件的基本要求是:高精度的面形質(zhì)量(透射波前/ 6pv ) 、高激光損傷閾值( 15j / cm2 ) 、良好的表面粗糙度rms ( 5nm ) 。
