Two extremely dense stars in an intimate dance are spinning around each other in just 5.4 minutes—making them the fastest known stellar partners in the galaxy, astronomers have confirmed.

To have such a speedy orbit, the stars must be moving at about 310 miles (500 kilometers) a second, the team calculates.

The whirling duo, known as HM Cancri, also has the tightest orbit of any known "binary" star system. (Related: "First Proof 'Tight' Double Suns Can Have Planets.")

Both stars are white dwarfs—the dense, white-hot remnants left behind when sunlike stars die. The stellar corpses are separated by no more than three times the width of Earth.

In such tight quarters, hot gases flow between the two stars, releasing huge amounts of energy.

"This is the most extreme example of one of these double white dwarf systems we have so far," said study co-author Danny Steeghs of the University of Warwick in the U.K.

经过4天的惊魂，我的域名终于又回到我身边了，我该拿什么来报答你我心爱的战友！

This is a Cuban tree frog on a tree in my backyard in southern Florida. How and why he ate this light is a mystery. It should be noted that at the time I was taking this photo, I thought this frog was dead, having cooked himself from the inside. I'm happy to say I was wrong. After a few shots he adjusted his position. So after I was finished shooting him, I pulled the light out of his mouth and he was fine. Actually, I might be crazy but I don't think he was very happy when I took his light away.

这是一个在南弗洛里达的爱好者拍的，他在他的后院拍到这只青蛙，他当时把一个小彩灯当作一个神秘物吃掉了，刚开始他以为它会死掉，但是它后来恢复了常态，当他把小彩灯拿出来以后小青蛙还活得好好的，也许青蛙还会责怪他把彩灯拿走。

Ext.onReady(function() {
   var form = new Ext.form.FormPanel({
       baseCls: 'x-plain',
       labelWidth: 55,
       defaultType: 'textfield',

       items: [{
           fieldLabel: 'Send To',
           name: 'to',
           anchor:'100%'  // anchor width by percentage
       }
       //一下是 Form 快捷方式
       keys:[{
         key:Ext.EventObject.ENTER,
         fn:doSearch,
         scope:this
        }]
       
   });
   
   //快捷方式执行的方法
   function doSearch(){
      alert('开始查找。。。');
   };

   var window = new Ext.Window({
       title: 'Resize Me',
       width: 500,
       height:300,
       minWidth: 300,
       minHeight: 200,
       layout: 'fit',
       plain:true,
       bodyStyle:'padding:5px;',
       buttonAlign:'center',
       items: form
   });

   window.show();
});

当然快捷键也可以直接放在Windows里面。


1：KeyMap构造方法如下。
KeyMap( Mixed el, Object config, [String eventName] )
参数说明：
el:HTMLElement元素或id号。
config:object，可以包含如下配置信息。
{
    key: String/Array,     //可以是数字，字符，Ext.EventObject.LEFT助记符以及它们组成的数组
    shift:       Boolean,          //shift/ctrl/alt键与key同时按下
     ctrl:        Boolean,
     alt :        Boolean,
     fn  :        Function,         //回调函数
    scope:       Object          //按键事件绑定范围
}
eventName:string 可选，其值为keydown等。

2：新建立一个KeyMap：

  var el = Ext.get("idv");  
  var keympTest=new Ext.KeyMap(el,{  
    key:Ext.EventObject.ENTER,//此处写为Ext.EventObject.ENTER亦可  
    //ctrl:true,//此行代码若存在，则fn在ctrl和key同时按下的情况下触发，此处是ctrl+enter  
    //shift: true,    //同上
    //alt: (true/false),//同上    
    fn:handerMethod,  
    scope:this  
  }  
  );  
  keympTest.enable();//使当前keymap配置生效  



3：向以存在的快捷方式加入新的热键。
  keympTest.addBinding({  
    key:'\r',  
    shift:true,  
    fn:handerMethod,  
    scope:this  
    });  
    keympTest.enable();  
  });

嘿嘿，既然买了Googel手机，最好拿来干什么呢？拿来写微博吧，嘿嘿。。。。

JSP的扩展标签，虽然在以前的项目很少用到，但是今天还是做了一个学习，以备不时之需。
