Strengths: Possesses an NBA ready body that is strong enough to absorb contact in the lane and finish … Has three point range on his jump shot … Back to the basket skills are highly developed … Owns a nice turnaround jumper … Excellent finisher who is blessed with cat like body control to get off even the most difficult shots in traffic … Tough minded player who enjoys physical play and will not back down from a challenge … Unselfish player with the willingness to set-up open teammates … Physically he has all the tools needed to be a quality defender: quickness, good hands, long arms and intelligence … Crafty scorer who uses a number of fakes and his leaping ability to create scoring opportunities for himself … Solid rebounder due to his athleticism and body strength … Smooth player on the floor who lets the game come to him rarely forcing things … Coachable player with a great work ethic to improve … Does a great job of creating contact to draw fouls … Excellent finisher in transition where he will finish with flair … Emerging as a player who understands how to effectively move without the ball

优点：拥有为进入NBA做好准备的身体。在三秒区内足够强壮去承受身体接触然后得分。拥有3分跳投的能力。背筐技能有很大发展。。。转身跳跃很快。一个享受于身体对抗而且面对挑战不会退缩的有坚韧思想的运动员。不自私的球员，心甘情愿去团结队友们。。。身体对抗上他有作为高质量防守着所需要的所有手段：迅速的移动，很大的手，修长的胳膊，而且有优秀的篮球智商。一个会使用很多假动作并能用跳跃能力为自己创造得分机会的狡猾的得分者。他的运动能力和身体优势使他成为扎实的篮板手。在比赛中很少强迫某事的平静的球员。提高了工作道德并服从教练的球员。。。会很聪明的造对手犯规，攻防转换中用天赋得分的优秀的进攻终结者。展现了他是名知道怎样在无球时进行有效而且实用的移动的球员。

The model has the following features: 1 The security information provided by the assessment result is more dependable because of the consideration of some main uncertain factors; 2 The improved analytic method of power system DSR and the dynamic equivalent technologies are applied to reduce the computing time and to make the model more practical; 3 Step-up assessment strategy is adopted in order to balance the precision and computing time requirements; 4 Decompounding of system insecurity indexes to each system component, or to each generator and consumer, and the visualization of assessment results, will help the operators to understand the security status of the power system more clearly; 5 The assessment results can be beneficial to the preventive control in traditional power systems and the security pricing in power market environments.

模型具有如下特点： 1由于综合考虑了一些不确定因素对系统安全性的影响，使得评估结果更加可靠； 2采用求解电力系统动态安全域的改进解析法，结合动态降维技术，大大减少了动态安全域的计算时间，使得模型比较实用； 3采取逐步递进的评估策略，以适应计算精度和计算时间要求； 4可定量分解出各元件或各发电与用户对系统不安全的贡献，配以形象直观的评估结果显示，使操作人员清楚了解系统的安全状况； 5评估结果在传统电力系统可帮助制定预防控制措施，在电力市场可用于安全性定价。

Firstly, there are less secure and efficient threshold schemes; secondly, the research on multi-secret sharing is rather weak; thirdly, usual verifiable secret sharing don't consider the partners' anonymity, while it is just people's expectation. Last but not least, the problem of variety on shares is becoming a more obvious restrict of efficiency, especially in the facets of the lost and being districted of shares. On the application of verifiable secret sharing, there are also two inadequates : on the one hand , verifiable secret sharing has been used in much threshold cryptography but in less verifiable signatures.

然而，经过认真总结、分析该领域目前研究的发展状况（具体结果将在第一章给出），我们发现在可验证秘密分享的研究方面，仍有下列四个不足之处：一是现有的安全、高效的门限方案不多；二是对多秘密分享的研究非常薄弱，在已有的文献中还见不到安全、实用的可验证多秘密分享方案；三是通常的秘密分享方案没有考虑秘密分享者的匿名性，而这恰恰是人们所希望的；四是秘密分享者的动态管理问题已经越来越明显的制约现有方案的安全，尤其是密钥份额丢失或被破坏时如何恢复更是没有被深入探讨。

For the cold winter, the hollowing of the sweaters in this way is not useful.

对于寒冷的冬天来说，镂空成这个样子的毛衫实在不实用。

Memory foam mattresses are not only healthier, they are also a more sensible investment than old-fashioned inner spring mattresses.

记忆床垫不只是健康，它更是比过时的弹簧床垫更实用的投资。

Personal and practical gifts will resonate with celebrants again this year as more people will look to sweaters, winter accessories and other clothing options, in place of jewelry or an evening out.

个性化和实用的礼物今年将更能引起人的共鸣，因为有更多人希望拥有毛衣、冬天服饰和其他服装选择，而不是珠宝或者晚餐聚会。

However, in our case we are more concerned with the insurance of the absence of undesirable substances in all textiles and clothings.

但是从实用的观点出发，我们更应关注的是怎样确保纺织品和成衣制品上不含有害物质。

His customers are Chinese businessmen, a hardy, self-sufficient bunch who want clean rooms, a desk, a television and internet service and are not fussy about pools, minibars or any other fluff.

这些精英们果敢强干，收入丰裕。他们需要的只是一间整洁的房间，里面有张写字台、一台电视机并且可以上网就够了。他们不在乎有没有游泳池、酒吧间和其他不实用之物。
