  8. The object of single photon emission computed tomography ( spect ) is to reconstruct an unknown radioactivity distribution inside the body from projection data consisting of the number of photon collected on a collimated gamma camera. these projections are not simple line integrals but have point - spreads due to the imperfect collimator of the detector and attenuation due to the compton scattering. so

    這種投影數據與透射ct中的數據不同，由於存在著光子的點擴散（由準直器引起）和衰減（由散射引起） ，已經不能用簡單的線積分來描述這個問題，因此相對于透射ct而言，這個領域將面臨很多困難。
  9. 4. in this part, we obtain the empirical bayes estimation for the parameter of the gamma distribution families y (, 1 / 2 ), and obtain convergent rate

  12. At first, based on the 272 station monthly precipitation in china, the paper described the heterogeneous of the spatial distribution precipitation by use of the curve of lorenz and the coefficient of g. the results show that the heterogeneous of the spatial monthly precipitation in summer is stronger than in winter. based on this describing, the probability distributions function of the spatial distributions are fitted by use of the gamma distribution model, and this general principle is examined. the results show that the gamma distribution is good on describing the heterogeneous of the spatial distribution precipitation in china
