( 2 ) our experimental results have shown the topographycal distribution of the cfs of neurons in a - 1. generally the neurons with high cfs laid in the rostral part of a - 1, and the neurons with low cfs laid in its caudal part. the similar isofrequency strip was observed in a - i cortex
（二）大鼠皮層a區聽神經元的特徵頻率（ cf ）分佈具有分域特性， cf為高頻的神經元分佈在a區嘴側， cf為低頻的神經元分佈在a區尾側，實驗還發現在a區的內外側方向有類似的等頻帶存在。Overseas buyers are now inclined to maintain a low inventory level. their orders thus tend to be more frequent, in smaller amount, and require quicker delivery time, generating demand for the air cargo sector
現時海外買家均傾向維持低存貨水平，因此，他們改為較頻密地發出訂單，但訂貨數量較小，又要求在較短時間內交貨，這個趨勢為空運業帶來不少需求。The lifetime of particles co - doped with li + and na + increased as compared to that of un - doped one. however, the lifetime decreased as co - doped with other dopants. in addition, we also studied that ultraviolet ( uv ) light - induced spectral change in eu3 + - doped aluminosilicate glass and red to blue up - conversion emission of tm3 + -, yb3 + - doped y2o3 nanocrystals
（ 2 ）在紫外光輻照下， eu ~ （ 3 + ）摻雜的氧化物玻璃電荷遷移帶強度降低，通過研究輻照與激光的功率密度、波長的關系，發現這種變化屬于單光子過程，並具有頻率選擇性。According to the present situation and developing trends on condition monitoring and fault diagnosing of hydroelectric sets at home and abroad, and taking the technique of data fusion diagnosis hydroelectric sets as theme, this dissertation researches into data fusion fault diagnosis method based on dempster - shafer theory, and applies this technique to hydroelectric sets vibration fault diagnoses for the first time, and presents that using sub - band energy of vibration frequency to reflect the vibration intensity of hydroelectric sets
