In this paper, a new one dimentional microstrip PBG filter with triangular variation of the characteristic impendence without etching in the ground plane is reported.

本文给出了一种新的一维微带光子带隙滤波器结构，该滤波器的阻抗按照三角规律变化，克服了通常微带光子带隙滤波器需要在衬底上打洞或接地面腐蚀获得周期结构的缺点。

We're already in the thick of it, but beginning December 12th when Mars moves into an exact square with Uranus and the Moon moves into an exact opposition with Mars, and continuing through December 16th, when the Mars/Saturn square is exact, emotional emissions are even more dramatic—if that's possible.

我们已经几乎处在最危急的时分，而从12月12日开始月亮在双子座准确与火星对冲并与T三角形成大十字触发能量，直到12月16日火星准确与土星相刑，情绪的迸发将以极其戏剧化的方式表现出来。

In real option pricing, it is impractical to assume the present value of expected cash flow payoff as an exact number because it is a forecast one. Generally, the number is regarded as a triangular or trapezoidal fuzzy number to give its estimated interval values and the Black-Scholes (abbreviated as B-S) formula is used to price the real option.

针对实物期权定价中预期现金流收益的现值是个预测值，而采用精确值给出不太合理的问题，分析了三角模糊数或梯形模糊数给出它的区间估计值，并利用Black-Scholes公式为之定价的方法。

Based on the theory of tidal flow and sediment motion, a 2-D depth-integrated mathematical model for the Jiaojiang Estuary is developed by using explicit scheme of finite difference on the triangle elements. The results show that the rotary currents occurring in this area can be simply and effectively simulated by the model. Meanwhile, the suspended sediment concentration simulated is in agreement with the field data.

本文根据椒江口实测水文地形资料，从平面二维水流泥沙基本方程和基本理论出发，采用三角单元有限差分法对水流泥沙方程显示求解，对椒江口潮流泥沙进行了数值模拟，模型简单实用，较好地再现了具有旋转潮波性质的椒江河口水流运动特征，含沙量场也得到了基本正确的反映。

I'm writing a book about trigonometric and exponential functions.

我在写一本关于三角和指数功能的书。

It should be noted that whether the Country Point 4 is located inside the Exterior Opposite Angle Area or inside the triangle, it finally forms one same graphics which we call here Basic Triangle with Four Points Entirely Neighboring.

需要注意的是，国家点4无论落在三角形的外部还是内部后形成的四点全相邻布局，其基本图形是一致的，即四点全相邻基本三角；此时4色足够，而且这也是需要4色的基本图形。
