例句
- Through multiple generation calculation, the minimum point of penalty function value was obtained, then the optimalc reduction distribution was found.
通過粒子群多代運算，求出罰函數值最小點，得到壓下負荷最佳分配點。 - The modified penalty method is used to treat incompressible constraints, so that volumetric locking is avoided.
採用修正的罰函數法約束體積不變條件，避免體積閉鎖現象的產生。
