[听力原文]6-7W: We are now in Washington D.C., the capital city of America.M: It must be the political centre of America.W: That’ s for sure. People name it Washington D.C. since it lies in the district of Columbia. You know there is also a state named Washington in America. But it is in the Northwest of our country.M: I think this city’s name must be connected with President Washington.W: Yes. George Washington has been highly respected by the American people. To show their admiration and love for President Washington, they name their capital city Washington D.C.M: Oh, I see.W: Look, there is the Washington Monument. It is the highest needle shaped building in the world. The height is 55 feet.M: Will we visit the Library of CongressW: Yes. The Library of Congress is the largest Library in the world. The glass ceiling makes the library very bright.M: Your interpretation is so helpful. Why did people name this city Washington D. C.（）

通过控制层面选择梯度场和射频脉冲来完成MR图像层面和层厚的选择。在完成了层面选择后还必须进行层面内的空间定位编码。层面内的空间定位编码包括频率编码和相位编码。频率编码让来自不同位置的MR信号包含有不同的频率，采集到混杂有不同频率的MR信号后，通过傅里叶变换才能解码出不同频率的MR信号，而不同的频率代表不同的位置。在前后方向上施加了频率编码梯度场后，经傅里叶转换的MR信号仅完成了前后方向的空间信息编码，必须对左右方向的空间信息进行相位编码，才能完成层面内的二维定位。 磁共振利用______梯度进行层面选择时，可以减小层厚
