 Let λ0 be a real number, X be a vector, then the numbers in the form of λ0+λ are referred to as hypercomplex numbers or quaternions. This paper contains two parts:1.Algebraic operations of quaternion are defined by utilizing the knowledge in vector algebra and the fundamental properties of algebra of quaternions are derived.2.Rotation of a rigid body about one fixed point is described in algebra of quaternions. 设λ_0为实数,λ为矢量,形如λ_0+λ的数称为超复数或四元数。本文包含两个部分: 1.用矢量代数的知识定义四元数的代数运算,导出四元数代数的基本性质; 2.用四元数描述刚体绕固定点的转动。 Let K be any skew-field with central field F. A matrix A=(a_ij)n×n over K is called centralized if the characteristic matrix λI-A can be reduced by some elementary transformations into the following diagonal form:such that are all manic polynomials over F.The determinant of a centralized matrix A=(a_ij)n×n may be defined by (1) asfollows:and then the famous theorem of Hadamard can be generalized as in the following:Theorem.

If A=(a_ij)n×n is a non-singular centralized matrix over the skewfield of quaternions, thenand the equality sign holds if and only if the columns of A are all muturally orthogonal.This theorem may be proved by the following three lemmas:Lemma 1. If A is a centralized n-rowed square matrix of quaternions, then sois andLemma 2. For any n-rowed square, matrix A of quaternions, the. following two matrices are always centralized:andLemma 3.
