This study showed that the mt and sharpness of frequency tuning curves increased as the sound direction changed from contralateral to ipsilateral azimuthal angles. it suggests that sound direction effect on frequency tuning may be through the complex interplay between the excitatory and inhibitory inputs. the application of gaba ( a ) antagonist, bicuculline, lowered all mts but the application did not abolish direction - dependent variation in mt

以英語同義詞為基礎,對比英漢同義詞的來源,類型以及它們在語義的輕重和側重點、感情意義、語體色彩、搭配意義、位置分佈以及詞性句法功能,揭示其異同,對提高同義詞辨別能力與語言運用能力有積極作用。The results indicates that the cubic logarithm polynomials can accurately reconstruct the raw thermal images in the experiment, and can effectively suppress the interference to defect recognition caused by random noise and uneven heating in the pt testing of composite laminates ; the digital images from data reconstruction have clearer defect display or higher defect resolution than the raw thermal images, and the quadratic coefficient image of cubic logarithm regression shows the highest snr
結果表明利用三次對數多項式回歸即可精確地重建本次實驗的原始熱像,同時能有效地克服復合材料層壓板脈沖熱像檢測中隨機噪聲和加熱不均效應對缺陷識別的干擾;經過數據重建后所作的數字圖像比原始熱像有更高的缺陷顯示度或分辨力,其中以三次對數多項式回歸公式中的二次項系數所作的數字圖像的信噪比最大。Afterwards, in order to decrease the contradiction between the more complex and mass remote sensing image data and relatively slow speed of information extraction, an improved sfim image fusion method is proposed. this modified algorithm is on the base of sfim fusion technique, combines ihs method and sfim method and then replaces the former mean filter by an adaptive weighted mean filter. compared with the results of several common fusion techniques through a set of simulation tests between multispectral images and panchromatic images, it is proved that the new method can get an excellent result for the aim of improving spatial resolution while preserving the spectral information of multispectral images
論文的主要工作和成果包括:在像素層,論文研究了多傳感器數據融合理論及遙感圖像預處理的過程和步驟,歸納了多源遙感圖像像素層融合的常用演算法,並針對目前遙感數據呈海量化、復雜化這一發展趨勢同遙感信息提取的能力和效率滯后這一矛盾,在sfim演算法的基礎上,將ihs變換與sfim相結合,將原演算法中的均值濾波器改進為自適應加權均值濾波器,提出了一種改進的sfim演算法,通過對一組多光譜圖像和全色圖像的雙傳感器融合模擬對比試驗,證明了該演算法在保持原多光譜圖像光譜信息的同時,能夠有效提高融合圖像的空間分辨能力。3. the modeling method based on mechanism analysis and identification method always exits unmodeled high - order part and the modeling method based on neural networks usually has not good enough generalization capability. we fuse above two kinds of modeling method and put forward a hybrid modeling method based on mechanism analysis, identification and rbf neural networks. this paper proposed a hybr id modeling method based on mechanism analysis, identification and rbf neural networks. first, get a object ' s low - order model by the mechanism analysis and identification method. second, adopt rbf neural networks modeling method to compensate unmodeled high - order model. the sum of the low - order model and high - order model is the hybrid model. this kind of hybrid model has more accuracy than a model based on mechanism analysis and identification and has more generalization capability than a model based on neural networks
針對基於機理分析和辨識的建模方法總是存在未建模的高階部分,精度不夠高和神經網路建模方法泛化能力差的缺點,將這兩種建模方法進行融合,提出基於機理分析、系統辨識和rbf神經網路的混合建模方法,首先採用機理分析和辨識的方法得到工業對象的低階模型,再用rbf神經網路建模方法補償未建模高階模型,這樣得到的混合模型,比單純基於機理分析和辨識的建模方法具有更高的精度,比單純的神經網路的建模方法具有更好的泛化能力。Business valuation based on modern economy is one of the most difficult and comprehensive professional work in asset appraisal, but also stands for the trend of the appraisal. as china implemented planned economy all the long in the past years, the concept of business value was proposed later than other advanced countries. the study on the theory and method of business valuation we made is relatively backward. all these lead to that we merely use cost method in practice. with the improvement of market economy, the validity of cost method is challenged. hunting for appraisal methods suitable for china circumstance has become more and more urgent. this thesis presents its own opinion on the adjustment of the basic frame of theory of business valuation. for the first time, it puts systems theory into the study of the theory base, and believes that the enterprise as a compound entity has higher efficiency than the sum of its constituent, and then proposes new appraisal assumption. aiming at the obscure understan ding, it analyses a group of conception related to business valuation. after giving a whole analysis and study, this thesis indicates the income approach which emphasizes earning - capacity of a enterprise should become the correct choice of china, and makes a further study on the origin - features and feasibility of this method
植根于現代經濟的企業價值評估是資產評估中綜合性最強,技術難度最高的業務之一,也是評估業未來的發展方向,由於我國過去長期實行計劃經濟體制,企業價值概念的提出和運用時間較晚,缺少現代經營理念的積累,企業價值評估的理論與方法的研究比較滯后。本文試圖以理性分析和案例分析相結合的方法,系統研究和分析企業價值評估的基礎理論及其現實條件下,適應我國經濟發展的評估方法,以期為構建有中國特色的企業價值評估理論和方法體系做一些有益的探索。文章以企業價值評估的基本概念為起點,在對眾多關于企業性質的學說和理論觀點進行概括抽象的基礎上,指出了整體性、持續經營和盈利性是企業的重要特徵,依據企業的整體性運用系統方法闡明了企業的價值大於組成企業的單項資產價值之和,據此提出了反映企業價值評估特點的有機組合增殖假設;依據盈利性的特點,強調了企業價值評估的核心應為企業的獲利能力,而不是組建企業的成本;對企業價值、企業價值評估含義、特點的論述以及對相關概念的辨析表明了作者的個人觀點和文章的基本定位,而從評估目的入手劃分的以產權變動為目的的企業價值評估和以財務決策為目的的企業價值評估與企業價值評估的假設、評估核心共同決定了評估方法的選用。The relation of tthe ccd sensor imaging resolution and the mtf is gotten. when the mtf of space remote sensing camera is higher and the contrast of object is higher, it can be believed that the resolution of ccd sensor imaging is 1. 6 times of the pixel dimension, in the mean while the mtf decreases 32 %
通過模擬得到了ccd探測器的目標影像的分辨力與ccd像元尺寸的關系,當航天光學遙感相機的mtf較高(模擬中鏡頭的mtf = 1 )且目標為高對比度時,得到ccd探測器的目標影像分辨力是其像元尺寸a的1 . 6倍,其光學調制度傳遞函數mtf下降32的結果。Meanwhile the beamspace high - resolution methods possess better resolution performance than the element - space high - resolution methods in the condition. the bmode method and the broot - music method show the best resolution performance among the five beamspace methods
