3 、糖精溶液口腔灌流組大鼠丘腦外側背核（ ld ）和丘腦腹后內側核（ wm ）內比k免疫陽性神經元數均顯著多於對照組：卜兀1腹腔注射組大鼠的ld和丘腦內側背核外側部（ mdl ）內lek免疫陽性神經元數顯著少於對照組。

Fortunately, we can solve this problem by using ap ( alternating projection ) algorithm, by this way ; the computational load can reduce dramatically. doa estimation is mostly research base on linear array, because of the limitation of linear, it can estimate the azimuth only ; solid array can estimate the azimuth and elevation, in this paper, the solid array is used for doa estimation ; when the signal sources are uncorrelated, the music algorithm is chosen, using mdl / aic algorithm, we attain the signal number of sources

本文採用立體六元陣進行測向，在非相干信號源條件下，採用music演算法進行doa估計，採用基於信息論原理mdl準則或者aic準則判斷信號源數目，通過對陣列流形的研究，指出基於圓陣的陣列流形具有的某種對稱性，利用該對稱性來降低運算量，並且通過對演算法的研究，提出用維數較小的信號子空間或噪聲子空間來計算空間譜，進一步減小music演算法運算量。

4. the numbers of lek - immunoreactive neurons in ld, mdl and vpm of cta group were remarkably fewer than those in saccharin intraoral infused of cta group were remarkably fewer than those in saccharin intraoral infused group. the numbers in ld, mdl, vpl and rt had no significant difference with those in licl i. p

4 、 cta組大鼠的、 mdl以及wm內陽性神經元數顯著少於糖精溶液口腔灌流組；而其ld 、 mdl 、丘腦腹后外側核（ vpl ）以及匠腦網狀核（ rt ） 「內lek免疫陽性神經元數與lici腹腔注射組相比均無顯著差異。
