论文摘要：根据切比雪夫定理，提出了一种适于FPGA实现的函数逼近新方法：通过区间映射关系，将函数定义域映射到较小的逼近区间内，并按照交错点对逼近区间进行分段，分别求出每段的最佳一致逼近多项式，对函数进行分段逼近，最后将逼近结果反映射，得到最终的函数计算结果。

In each case, only one of the two possible expected ratios was accepted in all markers, furthermore, no significant deviation from Mendelian inheritance (two-tailed binomial test, P≥0.053). To investigate the polymorphism of AFLP markers, and the genetic diversity in populations of H. discus hannai, eight abalone populations were analyzed by using a total of six AFLP primer combinations. The mean percentages of polymorphic loci of the eight populations were 48.65%, 50.50%, 51.17%, 50.51%, 58.90%, 60.07%, 68.92% and 54.05%, respectively.

而我们的池厚与分散度关系的实验已说明了厚池中键长键角不归一，当小球标准差为8.4％时，键长键角的变化可以用连续网络的非晶模型来描述，此模型的非晶结构的骨架与单晶相同，但键长键角有小量的无规性。

但在井斜控制方面的研究还很欠缺。

Results (1)The agger cells existed in 99% of the cases, the development of the agger cells in 9～16 years old children, and adult had no difference;(2) The morphology of agger cells differed widely, but its relationship to the anterior border of the middle nasal concha, bulla ethmoidalis and nasolacrimal canal was quite stable;(3) The upward pneumatization of the agger cells was not related to deviation of nasal septum, but closely related to the development of the frontal sinus;(4) The anterior nasosinusitis often influenced the agger cells and might result in hyperosteogeny.
