library that extends the Collection structure of the Java standard library. It provides many powerful data structure types and implements various Collection tool classes. As an important component of Apache open-source projects, Commons Collections is widely used in the development of various Java applications.
Commons Collections implements a TransformedMap class, which is an extension of the Java standard data structure Map interface. This class automatically performs specific modification an
requirements of safe and economical operation.2, the type of BusbarBus Bar According to the structure is divided into hard bus and soft bus. The hard bus is divided into rectangular bus and tubular bus. Rectangular busbar is generally used in the main transformer to the Power distribution room, the advantages of the construction and installation of convenient, small changes in operation, large load flow, but the cost is higher.The soft bus is used ou
decorated with a map, A transformer is used to determine the rules (or factory) that are populated when the key value does not exist.
The code is as follows

Association describes the association between classes. You can define the multiplicity Association in the classes at both ends.
In this figure, an owner can own one or more parcels. Similarly, a parcel can be shared by one or more owners.
Multiple associations limit the relationship between object classes and other objects. The symbols used for multiple associations are as follows:

device is different from the 0 V level of the B point, this will lead to a large amount of current flowing from devices with high potential to devices with low potential. How can we solve this problem?
The transformer (isolating transformer) device appears. It filters the differential signals sent by PHY with the difference mode coupled coil to enhance the signal, and is coupled to the other end of the con
greatly reduced, and the load carrying capacity is greatly improved. In the case of asymmetric load, the neutral point offset will be relatively small, so it returns to normal.
Can I use a high-voltage wireless Transcoder to display the same phase for the 10 kV substation and the 10 kV substation's outgoing core?
Yes, if it is just a single-core phase, but if it is necessary to make a vector, it needs to be done by the Power Bureau when there is load.
In fact, the high-voltage phase meter is a

Let me tell you a embarrassing story of how I wasted three weeks of the time during graduate school six years ago.
It is the end of my second semester of coursework.
I had taken all of our exams early and all my projects for the semester had been.
Since My school obligations were essentially nil, I started experimenting with (automatically) identifying

Put the sorting statement behind the total number query. Sometimes when you comment out the cache, it will still be affected. You need to delete the comment statement.
