This paper proposes an universal e-cash system based on partially blind signature which can be divided to small pieces of arbitrary number one time, so-called single-divisibility.

针对通用电子现金系统的难点在于其可分性，本文提出的方案以SK00系统为基础，实现其转移性(SK00公开问题)，并给商家颁发电子执照行使银行的部分职能，进而提出了一个显式可分(即一次性任意分割电子现金)的离线电子货币系统；同时利用以前的技术实现了一个采用树型结构的可分电子现金系统，并比较了这两个方案和以前方案的效率；二者安全性基于离散对数问题和强无碰撞Hash函数安全性；最后本文利用代理签名给出了一个新的部分盲签名方案。

The paper according to fractal autoregressive integrated moving average process models network self-similar traffic, estimates fractal dimension through fractal analysis methods directly and indirectly, and emphasizes on rescaled range analysis.

本文由分形自回归整合滑动平均流量模型产生自相似性数据。针对流量分形维数的求解，本文分别从直接估计和间接估计两个方面进行研究，采用分形分析方法对产生的业务流进行统计分析，其中重点讨论了变标度极差分析法。

This scheme divides center difference to forward and backward one-side difference operators which are combined in 4-6 steps Runge-Kutta time integration.

此格式将中心差分算子分成前向和后向两个空间单边差分，然后在4-6步Runge-Kutta时间积分中使用单边差分组合。

We performed a simulative test, which confirms that wavelet analysis can separate annual wobble and Chandler wobble. Our results show that this method can be used in astronomical geodynamies effectively. This paper is divided into two parts. The first is about statistic characteristic of polar motion. Polar motion includes secular motion, long period fluctuations, Chandler wobble, annual wobble and high frequency wobble. The secular motion is 3.4mas/year and towards 760W meridian. Long period fluctuations have difference periods in x-axis and y-axis. They are 31.7-year and 24-year in x-axis and 28.5-year and 22.9-year in y-axis. These 2~? decades fluctuations have an amplitude of about 30 mas , and are very nearly linearly polarized, with the observed motion of pole being almost entirely along a line between 360E and 1440W. There is a 55.4-year wobble whose amplitude is 9 mas. The amplitude of the interannual fluctuations is about 4? mas. The amplitude of long period fluctuations decreased after 1970. The annual wobble is a steady wobble. It retrograde wobble is only 1/20 of prograde wobble in amplitude.

本文的工作主要分为两部分：第一部分是通过分析POLE97序列，我们对极移的统计特性有了一个较全面的认识，极移主要包括趋势项、长周期项、Chandler项、周年项和高频项：趋势项的方向是西经76°，速度为每年3.4mas；长周期项中Markowitz 项在X、Y两个方向有不同的周期，它们分别是：X方向的两个周期是31.7年和24 年，Y方向的两个周期为28.5年和22.9年它们叠加在一起是一个线偏振运动，最大振幅约为30mas，偏振方向在西经144°和东经36°之间；极移的长周期波动中还存在一个 55.4年周期的圆周运动，振幅约为9mas；十年尺度变化的振幅在4～6mas之间，在Y 方向十年尺度的成份比较多，它们的周期在X方向和Y方向不是对应的；从七十年代年开始长周期变化的振幅明显降低；周年项是一个振幅稳定的摆动，在X、Y两个方向的振幅略有差别，逆向运动振幅大约为顺向运动振幅的1/20；Chandler摆动的振幅自1900年以来经历了几次较大的变化，其中包括1915年和1955年两次极大值，振幅分别达到0&。25和0&。28，以及1925～1940期间小于0.09的过程，Chandler项在X、Y 两个方向的振幅几乎完全相等，其逆向运动振幅不到顺向运动振幅的1/50。

Wire resistive touch screen technology, the grass-roots to the voltage field in both directions through the precision resistor networks are added to the work of conductive glass surface, we can simply be understood as the voltage field in both directions of staggered working hours added to the same work surface, The outer layer of Ni-Au conductive layer is only just be used as a pure conductor, there are time-test, after touching the inner ITO contact point X-axis and Y-axis voltage value method measured touch point position.

五线电阻技术触摸屏的基层把两个方向的电压场通过精密电阻网络都加在玻璃的导电工作面上，我们可以简单的理解为两个方向的电压场分时工作加在同一工作面上，而外层镍金导电层只仅仅用来当作纯导电体，有触摸后分时检测内层ITO接触点X轴和Y轴电压值的方法测得触摸点的位置。

My stand-by time is 2 hours. But yours is 2 hours 20 minutes. Have you eliminatedprecluded 20 minutes' free time?

My son 5 years old, when two-year-old on the occasional nosebleeds, small, 4-year-old when more than three months on the stream once every 10 days for half a year and a half months ago on the flow time, and also more than the original, to the hospital, said blood tests are normal, the point of medicine at the children do not love the beginning of .8 month almost 32 days on stream, but also very large, went to the hospital check, blood test or normal, open points syrup, and eat Chinese medicine granules, not a week, drug use is also a day on the 15 o'clock a sudden nose bleeding out, exhausted all the methods normally used only finally stopped, six o'clock in the morning and a stream, though not at night, and also have more than the original (the child was afraid I worry that the deal did not tell my own, I was based on the many large blood on the ground and pumping his college paper used judgments), or normal blood, the cream of the point that no matter, I was pleased, but the children come back again every day flow, and sometimes more than once or twice a day, which is a headache for two days and asked him if he do not understand how that specific pain law, is not the teacher the past two days that he said he did not love school is really a headache or a headache, I was to determine if a teacher said he does not love the child's school is a small trick.

5岁男宝宝经常流鼻血，最近两天又说头痛怎么办我的宝宝5岁了，两岁多的时候开始就偶尔流鼻血，量少，4岁多的时候开始三两个月就流一次，半年前开始隔十天半月就流一次，并且也比原来多，到医院验血说都正常，开点上的药水宝宝不爱点。8月分开始几乎三两天就流，还非常多，又去医院查，验血还是正常，开了点药水，和吃的中药颗粒，没到一周，还正用药，一天夜里3点就突然鼻子向外大量流血，用尽了平时用过的所有方法才好不容易止住了，早上六点又流了一次，虽没有夜里多，也是比原来都多(宝宝怕我着急，这次没告诉我自己处理的，我是根据地上的许多大血滴和他用过的纸抽团判断的)，血还是正常，开了点药膏，说没什么事，我挺高兴的，可是宝宝回来又是每天都流了，有时一天还不止一两次，这两天说是头痛，问他又说不明白具体怎么疼法，是不是老师这两天说他他不爱上课就说头痛还是真的头痛，我正在判断中，如果是老师说的他就不爱上课当然是宝宝的小把戏。

Because the maximum plus scores is 54, which means the two teams all choose black card, and they will get 27 separately.

因为最大正分是54，也就是意味着两个组同时选黑牌，并且两组会分别得到27分。

A draw in Eindhoven coupled with a Milan defeat would end the Italian team's quest for a third UEFA Champions League crown because with both finishing with eight points the Dutchmen would progress having taken four points in the games between them.

如果埃因霍温战平外加米兰失利，意大利球队追求第三个欧洲冠军联赛的王冠的脚步将就此停止，因为两队同积8分，而荷兰人从两队间的2场比赛取得了4分，将继续前进。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
