<h3>ng-init初始化变量</h3>
<div ng-init="name='aurora';age='18'">
  <p ng-bind="name+','+age"></p>
  <p>{{name+','+age}}</p>
  <p ng-bind="name"></p>
  <p ng-bind="age"></p>
</div>
<h3>ng-init初始化对象</h3>
<div ng-init="hero={name:'aurora',role:'sup',line:'不管刮风还是下雨,太阳照常升起'}">
  <p ng-bind="hero.name+','+hero.role+','+hero.line"></p>
  <p ng-bind="hero.name"></p>
  <p ng-bind="hero.role"></p>
  <p ng-bind="hero.line"></p>
</div>
<h3>ng-init初始化数组</h3>
<div ng-init="heros=['曙光女神','堕落天使','魂锁典狱长']">

  <p ng-bind="heros[0]"></p>
  <p ng-bind="heros[1]"></p>
  <p ng-bind="heros[2]"></p>
</div>
 
<h3>ng-controller控制器</h3>
<div ng-controller="contr-2">
  First Name: <input type="text" ng-model="firstName">
  Last Name: <input type="text" ng-model="lastName">
  Full Name : <span>{{firstName + "," + lastName}}</span>
  Full Name : <span ng-bind="firstName + ',' + lastName"></span>  
</div>
 
<h3>ng-repeat遍历无重复集合</h3>
<div ng-init="names=[1,2,3]">
 <ul>
  <li ng-repeat="x in names">
   {{x}}
  </li>
 </ul>
</div>
<h3>ng-repeat遍历重复集合</h3>
<div ng-init="number=[1,2,2,3]">
 <ul>
  <li ng-repeat="x in number track by $index">
   {{x}}
  </li>
 </ul>
</div>
<h3>ng-repeat遍历对象</h3>
<div ng-controller="contr-3">
   <ul>
    <li ng-repeat="(key,value) in object track by $index">
     {{key+":"+value}}
    </li>
   </ul>
</div>
<h3>ng-repeat遍历对象(按原有顺序)</h3>
<div ng-controller="contr-4">
   <ul ng-repeat="obj in objs ">
    <li ng-repeat="(key,value) in obj ">
     {{key+":"+value}}
    </li>
   </ul>
</div>
<h3>ng-repeat遍历对象(属性详解)</h3>
<table ng-controller="contr-5">
  <tr ng-repeat="(key, value) in objs ">
    <td>学号:
      <span ng-bind="$index"></span>
    </td>
    <td>
      <span ng-bind="key"></span>:
      <span ng-bind="value"></span>
    </td>
    <td>是否为奇数?
      <span ng-bind="$odd"></span>
    </td>
    <td>是否为偶数?
      <span ng-bind="$even"></span>
    </td>
    <td>排行是老大?
      <span ng-bind="$first"></span>
    </td>
    <td>排行最小?
      <span ng-bind="$last"></span>
    </td>
    <td>排行中间?
      <span ng-bind="$middle"></span>
    </td>
  </tr>
</table>
<h3>ng-repeat start/end</h3>
<div ng-controller="contr-6">
  <div ng-repeat-start="(key,value) in objs">
    <p>学号:
      <span ng-bind="$index"></span>
    </p>

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存

三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。

首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。

据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
