数据库的完整性控制熟悉利用企业管理器为列创建DEFAULT约束、为列创建CHECK约束、为列创建UNIQUE约束、为列创建不允许为空约束、创建PRIMARY KEY约束、创建FOREIGN KEY约束(Integrity control of the database use Enterprise Manager to create the familiar column DEFAULT constraint, create a CHECK constraint for a column, create a UNIQUE constraint for a column, create a column does not allow null constraint, create a PRIMARY KEY constraint, create FOREIGN KEY constraint)

以齿轮系统动力学和非线性动力学理论为基础,针对齿轮系统时变啮合刚度和齿侧间隙耦合作用的具体特点,建立了齿轮系统非线性模型,并用数值积分和数值仿真方法对其在某些参数域中进行了非线性振动研究(Based on the dynamics of a gear system and the theory of nonlinear dynamics, co nsidering characteristics of coupling action of the time-varying mesh stiffness and the gear backlash, a model of the nonlinear gear system is developed. The nonlinear vibration is studied by using numerical integration method and numerical simulation in some parameter fields.)
