对窗

There is, however, another and more disturbing parallel between 2008 and 1932 - namely, the emergence of a power vacuum at the height of the crisis. The interregnum of 1932-1933, the long stretch between the election and the actual transfer of power, was disastrous for the U.S. economy, at least in part because the outgoin administration had no credibility, the incoming administration had no authority and the ideological chasm between the two sides was too great to allow concerted action.

不过，2008年和1932年还有一个更令人不安的共同点，也就是在危机高峰时出现权力真空。1932-1933年间的那次空窗期，从选举结束到实际权力转移之间的空档拉得很长，对美国经济是一场灾难，一部分归因於将下台的政府没有信用，将上任的政府又没有权力，而且双方的意识形态鸿沟太大，没有联合行动的空间。

After certifying the irreality of ideal filtering function, we can get a better filter selecting a proper window function. Comparing two actual filters, we designate a good"Panama hat"filtering function. Meanwhile, an effectively linear interpolating function is introduced to raise the image reconstruction quality. Describing its realizing steps on the micro-computer briefly, we reconstructed some images from the anlogue projections of some models. The number of projection views is 180, 100 same interval parallel lines per view; the size of reconstructed images is 64×64 pixels with 64 gray levels; the reconstructing speeds are 40" on PC-386 and 12"on PC-486, respectively; each pixel is 0.31mm.
