The DNG structure unit is composed of square split ring resonator and strip wire. The modified NRW method is used to extract the equivalent permittivity, permeability, and refractive index from the scattering parameters of the two-port waveguide with DNG structure. At the designed operating frequency, the refractive index approximates zero, which makes the nondirective electromagnetic wave tend to approximate plane wave along the normal direction of the superstrate and congregate the radiation energy.

以方形的SRR环和金属条带构成双负媒质结构单元，使用修正的NRW方法，通过放置双负媒质结构的二端口波导的散射参数，提取了等效的介电常数、磁导率和折射率，在所设计的工作加热板频率，折射率接近于0，可以将原本发散的电磁波整理成趋近于覆层面法线方向的近似平面波，起到能量汇聚的功能。

To overcome the shortcomings of the traditional active decoying theory confronting an ARM(Anti-Radiation Missile),the monopulse angle is utilized tracking principles to deduce in the Cartesian coordinate system the bias angle formulas due to multiple sources.

针对反辐射导弹传统有源诱偏理论的不足，从单脉冲雷达跟踪合成波阵面法线方向的理论出发，对多个辐射源的诱偏公式在三维空间中作了推导，对多目标影响建立了较通用的干扰模型并分析得到该模型具有当只有一个干扰源时，诱偏方位角偏差跟目标干扰源方位角之差有关的特点，同时诱偏仰角偏差也有类似的特点。

Computes so-called specular lighting, which refers to the way that glossier surfaces have noticeable bright spots or highlights resulting from the narrower scattering of light off the surface.

在 specular中，物体表面产生的颜色值不单单只是光线和表面法线的关系了，还牵涉到了眼睛矢量，即观察者的视线，随着视线的变化，物体表面的高光区也会随着不断变化。

Ignoring the flag in some files inverts the face normals for some faces, so it becomes invisible.

In order to remedy this kind of shortage, this paper presents a quick volume rendering method, for the finite element data field of dam seismic response, choices the slicing direction relying on the element surface which normal line has the smallest included angle with the view direction, slices elements to many quadrilaterals, blends the colors of these quadrilaterals by using OpenGL blending technology, and then superimposes all elements one by one.

为了弥补传统体绘制静止画面不能明确判断场值集中部位的不足，提出一种快速体绘制算法，针对大坝地震反应有限元计算数据场，根据每个单元法线与视线夹角最小的表面来选择剖切方向，将单元剖切成多个四边形面后，对单元的绘制顺序进行合理排序，利用OpenGL图形库函数进行颜色融合，再将各个单元依次叠加，从而生成了三维数据场的体绘制图。
