負相差
英文
negative phase contrast-
We analyse the dispersion of stock returns and have the tests of serial correlation. the results show that the trading mechanism has a significant effect on a number of characteristics of stock returns. first, the distribution of open - to - open returns has greater variance than that of close - to - close returns. second. the serial correlation pattern is quite different in the two return series. the open - to - open returns have negative autocorrelation coefficient, but the close - to - close returns is positive. further, employing an arma ( 1, 1 ) model we find that in the opening. returns exhibit higher residual noise and stronger dependence on past returns, reflecting stronger deviations from the random - walk form of the market efficiency hypothesis
主要表現為：一，開盤收益序列比收盤收益序列具有更大的方差。二，兩種收益序列的序列相關形式不同，開盤收益序列表現為負相關，而收盤收益序列表現為正相關。而且我們通過arma （ 1 ， 1 ）模型的進一步檢驗，發現開盤收益序列比收盤收益序列具有更大的殘差，更依賴于過去的收益序列，也更偏離於市場有效的隨機遊走形式的假設。So, author draws conclusions : shares structure of firm in share market is related to achievement of firm, and concentration degree of shares structure has negative relation with achievement of firm. that is to say : the higher concentration degree of shares structure is, the worse achievement of firm is ; the bigger proportion of corporation share is, the better achievement of firm is ; public share has influence a little on achievement of firm
因此，得出以下結論：上市公司股權結構與公司業績存在相關關系，並且股權集中度與公司業績負相關，即在中國國家股「一股獨大」的現狀下，股權集中度越高，公司業績越差；法人股所佔比例越大，公司業績越好；公眾股對業績基本沒有影響。All the turn - point year is around 1974. another feature of interdecadal variability of interannual relationship between winter sea - ice extent of davis strait and summer, july and august rainfall of 160 stations is that the interannual correlation pattern have changed from east - west pattern to " + - + " north - south pattern around 1974. the interdecadal characteristics of correlation distribution pattern of interannual relationship between winter sea - ice extent of davis strait and summer, july 500hpa height of northern hemisphere are : " - + - " pattern from the beginning of novoya zemlya island, by way of balkhash lake to japan sea which is strongly negatively correlated with the rainfall of north china at the same period before 1974 and " + - " pattern from the beginning of ural mountains, by way of bujr lake to hetao basin which is badly correlated with the rainfall of north china at the same period after 1974

這類逆變器由左右二個雙向boostdc / dc變換器構成，左右二邊是對稱的，所以整個電路構成了一個四象限變換器，我們可以恰當控制各功率管的開、關，使左邊的兩象限dc / dc變換器輸出一個帶直流偏置的正弦波，使右邊的兩象限dc / dc變換器輸出一個相差180度帶同樣直流偏置的正弦波形，這樣，負載zl上的電壓是左、右兩個dc / dc變換器電壓的差動輸出，正好可以消掉直流偏置，最終在負載r1上得到的就是正弦波。The paper summarized the research for the effects of different grazing intensity on grazing behaviour, grazing grass species and productivity of sheep in recent years, the result showed that : there was a negative correlation between the live weight gain per sheep and the grazing intensity, but there was positive correlation between the live weight gain per hectare and the grazing intensity ; feeding intake of sheep decreased when the grazing intensity become heavier ; there was not significant effect of different grazing intensity on sheep breeding indexes ; as long with the grazing intensity become heavier, the feeding time of sheep increased while resting and idling time decreased, but feeding intake per hundred mouths and daily intake reduced while intake velocity increased ; sheep feeding adaptability is relative ; the light grazing was beneficial to promote mutton quality, but mutton quantity and gross economy benefit was low
摘要根據近幾十年來放牧強度對綿羊放牧行為、採食植物組成和生產性能的影響進行了綜述，得出以下結論：綿羊的個體增重與放牧率之間呈線性負相關，而公頃增重與放牧率之間呈正相關；綿羊的採食量隨著放牧強度的加重而降低；放牧強度對母羊繁殖性能各指標影響差異不顯著；隨著放牧強度的加重，綿羊的採食時間增加，遊走、反芻臥息時間減少；每百口採食量和日採食量減少，而採食速度增加；放牧綿羊的嗜食性是相對的；輕牧有利於提高肉的品質，但是產肉量低，總的經濟效益不高。Application of main tansformer differential protection in primany negative - phase sequence system
