The property of the near field subwavelength imaging in a metal thin-film structure is investigated using finite difference time domain method based on Drude model.

采用基于等离子体物理模型的时域有限差分方法模拟了金属薄膜近场成像特性；采用薄膜传输矩阵方法计算了金属薄膜对倏逝波分量的放大作用。

Besides the field access time tests, I did the same sort of timing test for method calls.

除了字段接入时间测试之外，我还进行了相同的方法调用时间测试。

This flag allows the runtime to execute the type constructor method at any time it chooses, as long as the method executes before the first access to a static field for the type.

此标志使得运行库能够在任何时候执行类型构造函数方法，只要该方法在第一次访问该类型的静态字段之前执行即可。
