( 7 ) fe have discovered phoenicurus crythrogaster, prunella fulvescen. < ;, carduelis horneianni * etberiza citrine ] la and seiccrcus castaniceps. they are all new distribution in heilongjiang province
( 6 )通過實驗數據和相關資料的總結,提出關于遷徙鳥類的兩個假說「屏障迴避假說」和「棲址優選假說」 ( 7 )在2000 - 2002年的環志過程中,在西部的高峰鳥站獲得紅腹紅尾鴝( phoenicuruservthrogaster ) 、褐巖鷚( prunellafulvescens ) 、極北朱頂雀( carduelishornemanni ) 、黃? ( emherizacitrinella )和栗頭?鶯( soicercuscastaniceps )等5種黑龍江省鳥類新分佈種。The main results indicated that : significant differences exist in diurnal average transpiration rate and the range of diurnal transpiration rate ; the transpiration rate of sawtooth oak, amorpha, lalang grass varied with a regular double apex rhythm, but that of the rest varied with a regular single apex rhythm, stomatal conductance play a maximal important role in transpiration rate, temperature ( air temperature, the earth ' s surface temperature ) also influence the transpiration rate ; transpiration rate has prominent negative correlation with the relative air humidity, the biggest coefficient is 0. 866
筆者對日照沿海防護林幾種主要木本植物和草本植物的蒸騰速率和環境因子的關系進行了研究,結果表明: 8種植物日平均蒸騰速率和蒸騰速率日變幅各異;麻櫟、紫穗槐和白茅的蒸騰速率日變換呈現出雙峰式的變化規律,其它5種植物蒸騰速率表現為單峰式的變化規律;氣孔導度影響著植物的蒸騰速率,溫度(氣溫、地面溫度)是影響植物蒸騰速率的主要因子;空氣相對濕度和蒸騰速率表現為顯著或極顯著負相關,相關系數高達0 . 866 。Through the i 、 q component of ipix radar sea clutter data " s histogram analyses and by skewness and kurtosis computed, it is been shown that sea clutter amplitude is not rayleigh distribution ; through the comparison of amplitude histogram and distributed models with the same parameters, it is been shown that hh polarization clutter is lognormal distribution, whereas vv polarization is k - distribution ; at the same time the correlation function and power spectrum density are been analyzed, at last the correlation compound k - distribution stochastic sequences whose covariance matrix is been given are been generated through sirp algorithm
文中先介紹了海雜波幅度的有關模型,通過對ipix雷達海雜波數據的i 、 q分量的直方圖以及傾斜度和峰度進行了分析和計算,證明了海雜波幅度不服從瑞利分佈;使用幅度直方圖和相同參數下的各種分佈模型進行比較,得出hh極化符合對數正態分佈,而vv極化服從k -分佈的結論;同時對海雜波的相關函數和功率譜進行了分析,最後使用sirp演算法產生了給定協方差矩陣的相關復合k -分佈隨機序列。The results showed that the 11 measured cooking and eating quality properties and taste value have manium significance genetic difference ; among the cooking and eating quality properties, varietal variation coefficent of gel consistency, peak viscosity, break down, setback is relatively large ; every cooking quality property has a different correlation with eating quality property, initial pasting temperature, finial viscosity, consistency and setback have significant or maximum significant inverse correlation with taste value, while peak viscosity, break down has a postive correlation with taste value, amylose content and protein content are inversely related to taste value, but gel consistency are positively related to taste value another, the correlation among varietal cooking and eating quality properties is significant or maximum significant ; in the analysis of principal components, the cumulative percent of 4 selected principal components reached 90. 58 %, initial pasting temperature of large second principal components is small, but amylose content and protein content is high, finial viscosity, consistency are large
結果表明,所測定的11項蒸煮食味品質特性及味度值在供試品種間均存在著極顯著的遺傳差異;在蒸煮食味品質特性中,膠稠度、最高粘度、下降粘度值、粘滯峰消減值的品種間變異系數較大;糊化開始溫度、最終粘度、回冷粘滯性恢復值、粘滯峰消減值與味度值呈顯著或極顯著的負相關,而最高粘度、下降粘度值與味度值呈極顯著的正相關,直鏈澱粉和蛋白質含量與味度值呈負相關,而膠稠度與味度值呈正相關;在主成分分析中,被入選的4個主成分的貢獻率達90 58 ,其中第二主成分大的品種,糊化開始溫度低,直鏈澱粉和蛋白質含量高,最終粘度和回冷粘滯性恢復值大。The taboo - search algorithm and the ordinary genetic algorithm are combined in this paper and the new algorithm is named taboo - genetic algorithm. the new algorithm is applied into the matching search of domain and range in fractal image coding. the result shows that the coding time is decreased greatly when the compression ration and the peak signal and noise ration do not decline
后來把禁忌搜索演算法與簡單遺傳演算法相結合,提出了一種新的禁忌搜索遺傳演算法,並應用於分形圖像壓縮編碼的定義域、值域匹配搜索,從而在不降低峰值信噪比和壓縮比的情況下極大地改善了分形圖像壓縮編碼的速度。After analyzing the real match position and false match position from the correlation surface, the new method can search the real match position based on the feature of the peak on the correlation surface
由灰度相關計算得到的相關面,通過分析真實匹配位置和虛假匹配位置局部極大值峰的特性,找到了一種基於峰值特徵檢測尋找真實匹配點的方法。分享友人
