GTD

We use the Finite-difference Time-domain ( FDTD) method to compute the scattered field of an object possessing several scattering centers. The numerical diffraction coefficient of the scattering center under investigation is then obtained by solving simultaneous equations established via GTD consideration.

利用时域有限差分（FDTD）法提供的散射场，根据几何绕射理论（GTD）建立含有绕射系数未知量的方程组，通过联立方程组的求解，得到散射体边缘的数值绕射系数。

I am familiar with the major GTD online tools and their and weaknesses.

Getting Things Done ( GTD) is a method for organizing tasks so that you can focus your entire energy and creativity on completing those tasks in a stress free manner.

把事情做完（GTD）是一种组织任务的方法，它能帮助你集中全部精力和创造力，用从容的（无压力的）方式完成任务。

GTD should be adapted to fit your personal working style-it's not a cookie-cutter approach.

你应该使GTD适合你个人的工作方式 —— 它不是什么千篇一律的方法.
