  1. A full mathematical model of optimal flow pattern design withengineering constraints was put forward, based on modern optimal control theory. an optimal flow pattern design was presented for optimizing meridional channel of axial flow turbine. according to integral optimization of turbine stages, a full physical model and mathematical expression were put forward for proposition of optimal flow pattern, including all performance parameters in turbine stages. this problem was further recast into a typical form control to maximize specific performance index such as work or efficiency of stage with given initial state, fixed terminal condition and constraints for part of state terminal variables. the program was also worked out according penalty function method and conjugate gradient method. the optimal distribution of c1ur1 ( r1 ) was obtained according to constraint conditions and maximized objective function

    把近代最優控制論方法引入軸流透平葉片的設計，在優化的軸流透平子午通道內，建立包括透平級內所有性能參量的最優流型命題的完整的物理模型及其數學表達式，並歸化為一個在給定初始狀態、自變量終端固定、部分狀態變量終端受有約束的條件下，使級的某一性能指標（如級的功率）達到最優的最優控制問題，應用「代價函數法」及「共軛梯度法」編制計算程序，計算得到符合給定約束條件、並使目標函數取極值的最優環量分佈，結果是令人滿意的。
  2. This paper uses the method of tensor to proof the tenable condition of generalized plastic potential, discuss the mathematical essential of the associated and disassociated flow rule and the relation of the yield surface and plastic potential surface, reason the expression of plastic factor strictly. debate the limitation on drucker ' s postulate. subsequently, this paper gives the mathematical basis of constitutive theory involving the rotation of principal stress axes. so it is proved that the mathematical and mechanical foundation of the generalized plastic mechanic
