使用ADO的数据复制原型 这是一个几乎在七年前我试图做的数据复制原型。它的一些部份可能仍然很有趣。最初,它使用了一个建造在ODBC上的的专有库,但是它可被容易地修改以使用任何的数据库接口层。 演示例子使用ADO和MSDEV 中自带 Nwind.mdb MS Access数据库。 这个原型引擎使用一个实际的或者人工制定的唯一的数据库内索引来标识一个记录。 在插入记录时可以正确处理Auto-Number或Counter数据类型。通过初始化复制条目集合或复制器类的Init方法中的链接描述符来执行复制计划。参考DemoCopyHelper.cpp这个例子. - Uses ADO data duplication prototype this nearly the data
duplication prototype which I attempts in seven years ago to do. Its
some parts still very were possibly interesting. At first, it has used

uses in ADO and MSDEV brings Nwind.mdb MS the Access database. This
prototype engine uses to be actual or in the artificial formulation

correctly process Auto-Number or the Counter data type. Gathers or in

感应电机的运行
INDUCTION MOTOR RUN
(Currents and speed as state variables)
The motor is running at a specified load. After reaching steady state in an initialization first run, the initial conditions are established for a second run in which the load is pulsating. The dynamic equations are expressed in canonical first-order matrix form adopting currents and speed as state variables, and are solved using ODE45.
The user has the choice of selecting one of three common (dq) reference frames: STATOR, ROTOR or SYNCHRONOUS.
The torque, speed,and current responses are plotted. -INDUCTION MOTOR RUN
