Mike Krzyzewski is really a famous coach of Dream Team. She has coached north america men's basketball team for some time, that's clinched numerous medals for his country. Following Londonfl jerseys supplyn Olympic was over, Krzyzewski told The Associated Press that this game will be his final one as national coach, a job he's held for seven years. He had left open the possibility of swomen nfl jerseystaying with the team beyond the London Games, when practice on Saturday said these will be his last Olympics.When asked if he was sure, Krzyzewski didn't hesitate before again saying, "yecheap nfl jerseys wholesales," this will be his last game "If we could win it, then it might be three major championships in a row, i always do not know when that has been done because we haven't usually won http://govoriotkrito.bg/libs/nflcn08.htmthe globe championships," Krzyzewski said. "It becomes an enormous thing for the program." Whatever, he's an awesome coach. His achievement are going to be remembered by the country.cheap nfl jerseys

小型继电器和中间继电器的区别
小型继电器可以理解为体积较小,驱动电路及接点电流相对较小。
中间继电器有三个功能:
1、小型继电器作为驱动功率的转换——用较小电流驱动较大电流的负载,例如:驱动更大电流的接触器。
2、小型继电器作为电压的转换——将一种驱动电压转换为另一种电压,例如:将24V的驱动电压通过中间继电器驱动220V的接触器。
3、小型继电器作为电路的隔离——将输入与输出实现电路的隔离,例如:将晶体管输出的驱动信号通过中间继电器隔离,使其输出接点能够连接其他类型的或者更高的电压。
    也可以这样理解:能够实现上述三个功能的继电器,可以称之为中间继电器。其实小型继电器也可以作为中间继电器来使用,由此看来,可以以用途来区分。
