例句與造句

1. The paper consists of two chapters . in the first chapter , theory 1 [ 1 ] mainly by using the method of the law of the iterated logarithm with finite partial sum in wiener process proves hartman - wintner [ 1 ] law of the iterated logarithm for special finite partial weight sums
   本文正文分兩部分，定理1主要利用[ 1 ] wiener過程下的有限項(xiàng)部分和的重對數(shù)律，把hartman - wintner重對數(shù)律[ 1 ]推廣到對特殊加權(quán)部分和也成立。
2. The limit theory of law of the iterated logarithm have received more and more attentions , especially about identical independent random variables . but up to now , the studies are only for partial sums and , have n ' t shown any concern on the special finite partial weight suras . however , the partial sums and partial weight sums not only have the osculating aspects , but also have essential difference between them . so the studies for these play an important role in theoretical and applied setups
   因此對重對數(shù)律的研究引起了國內(nèi)外學(xué)者的興趣，對獨(dú)立同分布的隨機(jī)變量，許多學(xué)者做了大量的研究工作，但迄今為止這方面的研究仍限于部分和數(shù)列的重對數(shù)律，很少涉及到特殊加權(quán)和的領(lǐng)域，而部分和與加權(quán)和之間既有密切聯(lián)系，又有本質(zhì)不同，因此，這一問題的研究具有一定理論意義和應(yīng)用價(jià)值。
3. Let { xn ; n > 1 } be mutually identically independent random variables distributed according to the normal distribution , { sn , n > 1 } be finite partial sum series , the purpose of this paper is to investigate law of the iterated logarithm type results for special finite partial weight sum series { sn , n > 1 } , we assume that sn = a1sn + a2 ( s2n - sn ) + a3 ( s3n - s2n ) + . . . + ad ( sdn - s ( d - 1 ) n ) in the second chapter , theory 2 by using the method of literature [ 8 ] , we extend hartman - wintner law of iterated logarithm on the gauss distribution . we substitute negative correspond for independent . it extends the corresponding results in gauss distribution
   設(shè){ x _ n ； n 1 }是獨(dú)立同分布的且服從標(biāo)準(zhǔn)正態(tài)分布的隨機(jī)變量序列， { s _ n , n 1 }是其部分和數(shù)列，討論有限項(xiàng)特殊加權(quán)部分和{ s _ n ， n 1 }的重對數(shù)律，其中定理2利用文獻(xiàn)[ 8 ]提供的方法，在高斯分布上改進(jìn)了hartman - wintner的重對數(shù)律，取消獨(dú)立性用更弱的條件負(fù)相關(guān)代替，大大拓寬了重對數(shù)律在高斯分布中的使用范圍。
4. It's difficult to find partial weighting in a sentence. 用partial weighting造句挺難的
