So a good msa program tries to get a best balance between alignment quality and computation time 所以,那些取得對齊質(zhì)量與對齊時間最佳平衡的程序就是好的多序列對齊程序。
Abstract : the mechanical structure of washboard valve leveler is introduced , the alignment mechanics of curving bar and hemilateral pan of the valve is analyzed , the mechanical , the shape of washboard and the effect of alignment quality and efficiency cause by shrink - adaption range of the valve between two washboard are discussed 文摘:介紹了搓板式氣門校正機的機械結(jié)構(gòu),分析了氣門桿部彎曲校直和盤部偏歪校正的機理,討論了機器結(jié)構(gòu),托板形狀和氣門在兩搓板間的過盈配合量對校正質(zhì)量和效率的影響。
