例句與造句

1. By choosing some appropriate exponential weight functions we prove that the essential spectra and the eigenvalues ( except the simple zero eigenvalue ) have negative real parts , thus we get the locally asymptotically exponential stability of travelling waves ( al ) and ( a2 ) in some weighted spaces
   通過(guò)選用合適的權(quán)函數(shù)，我們證得在加權(quán)空間線性化算子的本質(zhì)譜和除簡(jiǎn)單特征值零以外的特征值均具有負(fù)實(shí)部。因此，我們得到行波( a1 ) ， ( a2 )在加權(quán)的l ~ 2 ( r )空間的局部漸近指數(shù)穩(wěn)定。
2. It's difficult to find exponential weighting in a sentence. 用exponential weighting造句挺難的
