解釋
虛數項-
An expression that is the sum of a real number and a vector and that contains four terms, one real and three imaginary
四元數一實數和一矢量的和的表達式，有四個項，一個為實數項，另外三個為虛數項 -
Finally, benns ' search of exchange with the big other ( as the fellow human ) can only be produced in the imaginary, while the conquest, or in psychoanalytical terms, the subjection of the other has been proved still to be necessary for writing production
所求的交流最終僅能幻想式地營造而出，而他者（作為次要之人）的征服或折服於此同時證實為書寫生產之所必需。 -
An extended hyperbolic mild - slope equation, which can take such terms as wind input, bottom friction and nonlinearity of wave into account, here has been deduced into a parabolic one in the form of a series of governing equations described with complex amplitude. it became a complete wave model when integrated with corresponding physical and imaginary ( open ) boundaries, and can be solved through the improved crank - nicholson or the well known alternating direction implicit ( adi ) difference method, both of which can accelerate the convergent speed, expand limitation of the mathematical method and improve the quality of the solution
本文基於綜合考慮底摩阻、風能輸入及非線性影響的推廣雙曲型緩坡方程，將其進行轉換，產生一個演變方程，其復振幅控制方程為拋物線性，並採用adi差分格式、改進的crank - nicholson格式及相應的物理和虛擬（開）邊界條件進行求解，以提高數值模擬的適用性、數值計算的穩定性、收斂速度及精度。 -
In chapter 2, we give some important properties of metapositive definite matrices, the expression of real and imaginary part about eigenvalues of real square matrices as well as the range of eigenvalues of real square matrices ( especially the range of their imaginary part ). on the other hand, we sum up, establish and extend some necessary and sufficient conditions of metapositive definite matrices roundly. in chapter 3, we give some important properties of complex positive definite matrices, the expression of real and imaginary part about eigenvalues of complex square matrices as well as the range of eigenvalues of complex square matrices. on the other hand, we sum up, establish and extend some necessary and sufficient conditions of complex positive definite matrices roundly. in summary, we discuss in terms of set theory the relation among real symmetric positive definite matrices, hermitian positive definite matrices and two types of generalized positive definite matrices - metapositive definite matrices and complex positive definite matrices
第一章：除引入hermite矩陣、 hermite正定矩陣和實對稱正定矩陣較重要的性質外，還建立了它們的其它一些重要性質，尤其較全面地總結和建立了它們的若干充分和必要條件；第二章：建立了亞正定陣的一些重要性質，給出了實方陣的特徵值實部和虛部的表達式，並導出了實方陣的特徵值范圍尤其是導出了其虛部范圍，同時著重較全面地總結、建立和推廣了亞正定陣的若干充分和必要條件；第三章：建立了復正定矩陣的一些重要性質，給出了復方陣的特徵值實部和虛部的表達式，並導出了復方陣的特徵值范圍，同時著重較全面地總結、建立和推廣了復正定矩陣的若干充分和必要條件；全文小結：從集合論的觀點出發，對已討論過的四類正定矩陣? ?實對稱正定矩陣、 hermite正定矩陣、亞正定矩陣和復正定矩陣之間的關系作了比較細致的論證與探討。
