It is the front of many inverter circuits, which can carry out the pressure, then what is his concrete realization idea? What are the impact variables? What are the characteristics? What is the essence? These should be questions that are of interest to beginners, including me. According to some of our previous impressions, Buck can be distributed by resistive load, while a transformer can achieve a lifting pressure. The transformer utilizes the inductor, the energy-transforming device. In fact,
Note: Before starting, check whether the customer's environment contains DC, DNS, DHCP, and other roles, and decide whether to recreate these roles based on the on-site conditions.
When operating this module, create a virtual machine to install Windows Server 2012 R2 Standard or datacenter.

only interested in three lines of code:
Hbitmap = loadbitmap (hinstance, text ("Bricks "));Hbrush = createpatternbrush (hbitmap );Deleteobject (hbitmap );Load the bitmap, create a bitmap image brush, and immediately delete the bitmap.
The result is correct, and the image painting itself is not affected because the bitmap used as the image painting is deleted.
In this example, we can also conclude that the bitmap is used to create a paint brush. In this case, the bitmap in the paint brush is a c

By the original DC motor speed control example can be seen in the stability of the current is not good, to achieve a long time stability, overshoot is large, steady-state error is not small enough, the oscillation is obvious.The original controller only proportional control, very coarse, when the gain is low, the steady state error is large, when the gain becomes larger, it will cause the motor current and acceleration oscillation.After considering th
Modify DC Tombstone Survival Time U Case Requirements How do I change the time limit for an authoritative restore? U Knowledge Tips When you delete an object (such as a user account, OU, and so on) in AD, the object is not actually deleted, but is moved to a special container. When the object is eventually deleted, it is determined by the tombstone's survival time. Tombstone lifetime refers to the time interval at which an object is deleted from the a
