The low efficency arise from two factors : one is that we do n ' t understand multibody system as deep as possible , resting on “ there are so many trees as one ca n ' t see the forest “ . the other is that the algorism should hardly avoids void computing possiblly - - adding , minusing or multipling by zero , and ca n ' t reach the precision computing - - each computing is necessary , and the latter computing use the formal results as it can as as possible 計算效率不高的原因有二、一是對機械多體系統認識深刻程度不夠,停留在“只見樹木,不見森林”的層次上;二是算法上應該竭力避免虛運算? ?與零相加減、與零相乘和重復運算等,但由于多體系統動力學的復雜性、強非線性和人們對其認識現有深度的不夠,故未能實現所謂的“精益運算” ? ?每步運算皆為必須,且后續運算應盡能借用已有結果。
