An experimental study of Bi(2223) - Ag tapes undergoing bending and straightening at 300 and 77 K has been performed. The special test equipment allows us to measure changes of the critical current in a short element of the tape during continual decreasing or increasing of the bending diameter...
一些外地的消费者听说了这种生态甲鱼之后,早早的将它预定。两斤重的甲鱼就能卖300元,在市场上属于非常高价的产品,而且供不应求,不愁卖。在茭白田中套养的甲鱼比茭白的产值还高,成功的帮助一些农民朋友致富。这就是结合当地的特色发展农业的正面例子,可见不管发展种植业还是养殖业,都需要有特色和眼光才能实现富裕。

A study was made of the effect of temperature (300 and 77 K) and orientation on the mechanical properties of bulk BSCCO 2223 and BSCCO 2223/Ag composites processed by hot-pressing. The unreinforced material was strongly textured and almost fully dense and its flexure strength was outstanding. ...
