According to the hypothesis of continuum, a tube with the corner strengthened is gained to make an equal of the frame-tube. B3-spline functions and parabola functions are applied to simulate the displacement functions of the frame-tube. The system of equations about the undetermined coefficients of displacement functions is deduced by using energy-variational principle, by solving which the displacement of the frame-tube is gained. Then the internal forces in the columns and beams of the former frame-tube are obtained according to the principles of elasticity mechanics.

The time-domain response of the induced currents on a scattering object irradiated by a plane wave with a Gaussian pulse in time is expanded as an associate Hermite series in this paper. Using the isomorphism of the associate Hermite function and its Fourier transform, the frequency-domain information can be obtained similarly to the time-domain expansion. According to the corresponding relation between time-domain analysis and frequency-domain analysis, and using the early-time response and the low-frequency information of the induced currents, the non-known coefficients in the expansion series can be decided. The entire responses of the induced currents on the scattering object in both time and frequency domains can be obtained at one time by simultaneous extrapolation computation using both the early-time response and the low-frequency information of the induced currents.

没有办法,自己试着换了个地图生成工具,谁知道换了没过一天内容页权重全降了,好多连载影片快照都变成了N天前的,地图那一样显示待定,不过地图里的内容不一样,以前生成的地图只有时间和地址,没有更新频率和优先级,后面用的在线生成工具有优先级和更新频率,不知道是不是因为后面的地图有优先级把内页默认的优先级别降低导致的降权还是什么其他原因,这里是站长们高手云集的地方,见多识广,我的地图现在一直都是显示待定状态,站是http://www.dy3166.cn,首页权重没有变,就是内页权重没有了,希望高手们帮忙找下原因,申明,本人在此发帖绝非炒作,是确确实实碰到了这个棘手的问题,希望高手们能够帮忙解答下,谢谢了。
