In this paper , some especial higher power equation be enumerated , just like binomial equation or reciprocal equation , for people can ' t fine common extract roots formula about five and above power equation 摘要基于五次或五次以上方程沒有一般通用的求根公式,本文列舉了一些特殊的高次方程的解法。
And the two analysis methods are more reasonable and combinable with the actual instance than the general seismic analysis methods . this paper mainly discusses the two methods of designing actual project and offers the results of the theory and data . the pushover analysis is essentially static analysis method 靜力彈塑性分析方法和時程分析方法比一般通用的振型分解反應譜抗震分析方法能夠提供更合理,更符合實際的結果,本論文的討論研究為實際工程設計中采用上述兩種方法時,提供了一定的理論及數據分析結果。
Yang and xie 9 developed a numeri - cal model for the moving boundary problem through reducing it to a fixed boundary problem by a coordi - nate transformation . it is necessary to reduce the a subsurface runoff parameterization with water storage and recharge based on the boussinesq - storage equation 623 computational cost of the groundwater model so that it can be applied to a land surface model for climate studies 文獻9通過一個坐標變換將運動邊界問題轉化為一個固定邊界問題,進一步改進了該土壤水模型的數值計算方法,使其減少計算量,達到能在一般通用的模式中實際應用
