a system of along-track mode sar based on the gps is established.by seeing the gps signal as a chirp,chirp scaling algorithm of this mode with large squint angle is investigated.chirp scaling algorithm is considered more efficient and widely applicable when the bistatic sar system is in side-look or small squint angle mode,but in large squint angle case,the errors caused by taylor expansion are so large that the algorithm could lose its precision.in such a case,an equivalent mono-static sar range mode which has fewer errors than taylor expansion with large squint angle is proposed to substitute the range history of bistatic sar.then bistatic sar images with large squint angles are gotten by common nonlinear cs algorithm.the effectivity of the method is verified by matlab simulation.
摘 要:建立了基于gps的顺轨sar系统模型,通过将gps信号等效为chirp信号,研究了在该模式下的大斜视角chirp scaling算法。在正侧视或小斜视情况下,cs算法具有较好的聚焦性能和广泛的适用性,但在斜视角较大的情况下,该算法将散焦而不能成像,因而提出了用等效的单基地距离模型来代替双基地距离历史的方法,解决了大斜视角情况下距离模型二阶近似误差较大的问题,并结合单基地非线性cs算法,实现了在大斜视角情况下的基于gps反射信号的双基地sar高精度成像,最后通过matlab仿真进行了验证。

Another area of study is size, which leads to the cardinal numbers and then to another conception of infinity: the aleph numbers , which allow meaningful comparison of the size of infinitely large sets.
另一项研究的领域是大小,这引起了基数,然后引起了无限的另一个概念:在阿莱夫数,使无限的大套的规模有意义的比较。

The speed of a computer is affected by the number of bits it can process at once. For example, a 32- bit computer can perform arithmetic and manipulations on 32-bit numbers, whereas a 16-bit computer must break large numbers into 16-bit quantities, making it slower.
电脑的运算速度会受到它一次可以处理位元多寡的影响,例如32 位元电脑一次可以进行32 位元的运算,而16 位元的电脑因为每次只能进行16 位元的运算,所以它必须将比较大的数打散成16 位元的量,所以这样会造成速度变慢。

Fri particular, the Wittmann-type strong law of larg numbers for independent random variables is generalized to the case of NA random variables. We also present the sufficient and necessary condition of the laws of logarithm, and we extend Teicher-type strong law of the large numbers for sequence of NA random variables. Some of the laws of iterated logarithm of Teicher-type, Egorov-type arid Wittmann-type for sequence of NA random variables are obtained. Then we investigate the rate3f ionvergcll( fbr series of NA randonl variables, we obtain soIne results fbr tl1e Iaws of theiterated logarithttl, the laws of logarithm and decreasing order fOr the tail sum.Risk itllttlysis tlleory is a sigIlifica11t part of insurance InatheInatics.
Wittmann(1985a)关于实独立随机变量列的结果,并给出了NA列强大数律成立的若干条件,特别建立了一般NA列对数律成立的充分必要条件,在二阶矩存在的条件下完整的解决了一般NA列对数律的问题,中文摘要2而已有的一些NA列对数律的结果可以由它推出,给出了NA列的Teiclier型强大数律,表明lbiChCI·(1979)给出的实独立随机变量列的强大数律可以减弱其条件等;建立厂不问分布NA列的Teicfl仪;Egorov,Petrov型有界重对数律,以及加权同分布NA列的有界重对数律,进一步推广了NA列的Kolmogory有界重对数律等,特别对NA列建立了Wittm洲型有界重对数律,而其证明方法与独立情形有很大不同,同时通过反例表明在与独立场合类似的条件下,独立列的Wittmann有界重对数律不能完美的推广到NA歹小惰形;最后研究了NA随机变量级数的收敛速度,给出了尾和下降的阶;尾和的有界重对数律,及尾和对数律成立的充要条件等,并通过反例说明 NA随机变量级数与独立随机变量级数在收敛速度方面存在的差异。

The factors favoring unionization drives seem to have been either the presence of large numbers of workers, as in New York City, to make it worth the effort, or the concentration of small numbers in one or two locations, such as a hospital, to make it relatively easy.
影响工会化趋势的因素,要么是大量工人的存在,如在纽约城,使之值得努力,要么是为了集中在一个或者两个地方如一家医院的少数人,使之相对容易。

The basic characteristics of the Stark map of Ba atom are as follows: in weak-electric field, the Rydberg states with small angular momentum numbers show a quadratic Stark effect, and those with large angular momentum numbers no longer degenerate and show a linear Stark effect, which is hydrogenic.
研究结果表明:在弱电场下,低角动量态由于具有较大的量子亏损而随着电场强度显示出二次Stark效应;而高角动量态由于量子亏损为零,并在电场下解除简并,随着电场强度的增加而呈现线性Stark分裂,具有显著的类氢性质。

These large differences were predominantly caused by differences in numbers of annual dicots and perennial, mainly woodland dicots while the higher total species numbers in the Netherlands were mainly the result of an increase in all annual species.
这些大的差异主要是所造成的差异,在人数每年双子叶植物和多年生,林地主要是双子叶植物,而高占总种数的数目,在荷兰,主要是由于增加了,每年都种。

The results showed that the rate of mating disruption was 71.1%-80.7% caused by 150-750 rubber pheromone dispersers per hm 2. The egg numbers were reduced by 79.4%-86.1%, 72.9%-84.7%, 58.3%-65.1% and 58 9% at the treatments of 750, 300-375, 120-150 and 30 rubber dispersers per hm 2, respectively. In large scale disruption demonstrations, numbers of egg masses decreased 82.4% and 73.2% at placements of 60 dispersers per hm 2 in mid season rice seeding paddy and in early season transplanting paddy, respectively.
结果表明,田间放置诱芯150~750个/hm2的迷向率为71.1%~80.7%;每公顷放置诱芯750、300~375、120~150个和 30个的迷向区卵量比对照区分别下降79.4%~86.1%、72.9%~84.7%、58.3%~65.1%和58.9%;每公顷放置60个诱芯的大面积迷向示范区中稻秧田和早稻大田卵块量分别比对照下降 82.4%和73.2%,早稻大田枯鞘丛率比对照下降70.4%。

This text is based on the work that analyse the problem having emerged about large-scale economic affordable residential district of city at the moment, in instance of the patterns in Xi'an. Through investigating living circumstances and building present situation, there are lots of requirement for economic affordable housing in Xi'an. As large requirement for premise, the question about choosing location large-scale economic affordable residential district in city is researched. As time as, it should be refer to the problem which were founded in others cities, then summarize a correct choosing location model for the practical situation, it could determent the location of large-scale economic affordable residential district of Xi'an.
