It is related to the variational inequality problem, bilinear programming, nonlinear equation. So there is actual meaning and theories value to study how to solve it.In recent years, many algorithms for solving the generalized linear complementarity problem are put forward. But they basically belong to the traditional iterative methods, and may not be efficient since the computing time required for a solution is greatly dependent on the dimension, structure of the problem and the complexity of the algorithm used. Different from the traditional algorithms, the neural network has many advantages on calculations and real-time applications for its inherent massive parallelism and electric circuit implementation.
近年来,人们对广义线性互补问题提出了许多算法,但这些方法基本上属于传统的迭代法,由于它们的计算时间极大地依赖于问题的规模、维数以及所使用的算法,因此很难满足实时并行的要求,与传统数值方法不同,由于内在的并行分布处理信息的特点及电路实现的潜能,神经网络有着许多计算上的优势和实时性的应用,自Hopfield提出著名的人工神经网络模型-Hopfield神经网络,并将其成功应用于优化问题后,用神经网络求解优化问题得到了相当深入的研究,并取得了许多重要的成果。

Blame it on SimX and DoriftoKids, they're painful to judge, simply because both of these two teams have done great in some aspects, but made some mistakes at other aspects of their run, after concluding their scores, I keep getting the same score between them, no if you watch the replay, you'll notice their runs aren't similar, but they both made a fair share of mistakes in order to share that same score over and over again , I have been reviewing my scores of all teams for 3 times, and reviewed the scores between SimX and DoriftoKids for 5 times, trying desperately to find the little details in which I can deduct the points on, but failed I was, so I thought to myself... why not just let the two teams in....
只能怪SimX和DoriftoKids,这两支车队太难分出优劣了,因为他们在比赛中都在一些环节发挥出色,也在一些环节犯了错误,每次为两队评分后,我总是得到相同的分数,但是如果你看了录像,你会发现他们的跑法是不同的,但是他们犯了差不多的错误以致于每次的评分都相同,所有车队的成绩我都检查了三遍,并且这两支队的成绩检查了五遍,尽全力寻找可以扣分的细节,但是失败了,所以我对自己说,两支队为什么不能都进决赛呢。。。

As the mine accidents happen frequently in recent years, the detecting technology for microseism becomes much more important. However, there is no advanced microseism detecting system at home. It's pretty important for microseisms denoising and Reversion. A wavelet denoising method is presented here to process microseism signal, and the microseism record can get high signal to noise ratio. Meanwhile based on the software of LabVIEW, s design of real-time detecting system for microseism based on virtual instrument is presented. The advantage of the virtual instrument was sufficiently exerted to achieve the real-time detecting and analyzing of the microseism.
以往基于DSP或其他单片机的微震系统,其资源的有限性很难达到理想的采集效果,同时也难以完成先进算法的实现,而对微震信号的去噪与还原在监测系统中起着很重要的作用;在深入分析小波变换的信号去噪方法基础上,对微震信号进行了处理,得到高信噪比的微震记录,实现了对噪声的有效抑止;同时在LabVIEW平台软件设计的基础上,实现了一种基于虚拟仪器微震实时检测的设计方案,充分发挥了虚拟仪器的优势,结果表明基于LabVIEW的微震系统能很好地完成实时监测及其分析。

Database is the new database that Baidu builds to enact a new rank law, in this database in establishing a procedure, should a lot of people discover how his website didn't appear in Baidu for some time afore not the Description part of capture website, and the website of others appears in afore-mentioned phenomena, from this we can conclude it is OK that Baidu is building new B database get test and verify, the website appeared in Baidu today's phenomenon, we should OK know Baidu has been in for next rank regulation prepares, and it is important that the next will not rank influence of regard as of label of Keywords, Description will not rank influence of regard as of label of Keywords, Description regular Baidu element, even it is met throw the helve after the hatchet, turn and should do new Description to affecting the rank of website keyword with the content of own capture, corresponding do later those who optimize is difficult will increase, and Baidu will let good website appear as far as possible searching an user at the moment, so we are the following heavy name a person for a particular job meets be website oneself content to rise!
数据库算是百度为了制定一套新的排名规律而建立的新数据库,在这个数据库的建立过程中,应该有很多人在前一段时间发现怎么自己的网站没有出现在百度不抓取网站的description部分,而别人的网站出现在上述现象,从这一点上我们可以推断百度在建立新的B数据库应该可以得到验证,网站在百度中出现了今天的现象,我们就应该可以知道百度已经在为下一个排名规则做准备,而下一个排名规则百度将不会把keywords、description标签看做影响排名重要因素,甚至它会完全放弃,转而用自己抓取的内容当做新的description影响着网站关键词的排名,相应的以后做优化的难将会加大,而百度将会尽可能让好网站呈现在搜索用户眼前,那么我们以后的重点将会是网站自身内容的提高!

Though, as I said, the executive and federative power of every community be really distinct in themselves, yet they are hardly to be separated, and placed at the same time, in the hands of distinct persons: for both of them requiring the force of the society for their exercise, it is almost impracticable to place the force of the common-wealth in distinct, and not subordinate hands; or that the executive and federative power should be placed in persons, that might act separately, whereby the force of the public would be under different commands: which would be apt some time or other to cause disorder and ruin.
虽然,如我所说,每个共同体的执行和外交权力本身确实区别明显,然而它们也很难分开,同时交给完全不同的人:因为这两种权力的行使都要求社会的力量,将共同体的力量交给两个独立互不从属的机构,这几乎不可能做到;或者执行和外交权力可以交给独立行动的机构,那么公众的力量将接受两种不同的命令:这迟早将引起混乱和毁灭。良好的人性,恰当的理性,和对上帝的信仰。一个种族若不能从经验中得到理性,上帝会让他们不断的遭遇,直至毁灭。

In chapter 1, the progress in study of the ruthenium complex oxides. especially the coexistance of magnetism and superconductivity in 〓 and 〓 are introduced. The introduction makes conclusion that all of the Ru-1212 and Ru-1222 compounds reported are accompanied by small amounts of SrRuO〓 impurities, this is to say that, it is difficult to synthesize pure samples of these two compounds by traditional solid state reaction. So the author think that the studies for new synthesis methods of ruthenate superconductors which is beneficial to the synthesis of new type precious metals superconductivity is very important till now.
第一章重点综述了钌系复合氧化物的研究进展,特别是其中超导电性的发现及其钌系1212、1222相铜氧化物超导电性和铁磁性共存的特征,在此基础上可以看出,至今文献报道所获得的Ru-1212和Ru-1222相化合物都含有少量的SrRuO〓杂相,即很难通过原有的固相反应方法得到纯相化合物,由此作者提出,现有钌系超导氧化物合成的新方法研究仍具有重要的现实意义,这也将更有利于探索合成新型贵金属超导体。

The analyses of electronic structures shows that the catalytic reactivities for H2 adsorption of the different surfaces are dependent on the numbers of s orbital bonding electrons around Fermi level for the uppermost layer metal atoms which interact directly with H2. It is easy to form vacancy for hydrogen atoms next to iron atom, which indicates that hydrogen atom cannot be escaped, but it is difficult to from vacancy for hydrogen atoms next to magnesium atom, which indicates that hydrogen atom can be escaped. Hence it is thought that the change of dehydrogenating properties of MgH2 with or without a little iron addition attributes to the weakened bonding between magnesium and hydrogen.
分析电子结构发现:空位缺陷有助H2吸附于Mg表面,与Mg(0001)表面最上层与H2直接产生吸附作用的金属原子在费米能级附近s轨道的成键电子数密切相关;在Fe合金化MgH2体系中,与合金化元素Fe近邻的H原子形成空位的难度增加,H原子较难释放;与Mg近邻的H原子形成空位的难度减少,H原子容易释放;Fe合金化导致Mg-H之间存在较弱的成键作用,因此,MgH2体系的解氢性能得到提高。

Suitable clearness and groove radius of ball bearings are obtained by experiment and calculation. The relationship between starting moment of ball bearing and various lubricants is analyzed. The measure for reducing the starting moment of ball bearing is put forward, it is the theory basis and reference for ball bearing design of small power unit system.The system is an unstable system when the 24-station ball pen tip production machine is running because of various interferences. It is too hard to describe the system by linear method, so the nonlinear formulation must be used.

If a "reasonable" notion of database consistency is to be supported (I.c. the database system is to enforce it automatically), there are bound to be" conflict" situations where one transaction comes into an access conflict against some other transaction. If await is to be avoided,some means of a negotiated settlement of the conflict must be provided, thereby dragging the users into the details of concurrency control.The single-database model is more appropriate-ate than the multiple-database model in an environment where it is difficult to determine in advance logical partitions of the database that correspond to work to be performed, and the users closely cooperate.
如果一个数据库一致的合理观念要得到支持(即数据库系统要自动实行这个观念)、一定会有矛盾的情形产生、在这种情形中一个业务与其它业务产生存取矛盾如果要避免等待,就必须提供某种协商解决矛盾的方法,从而迫使用户详细了解并行控制单一数据库模式在某一种环境中比多个数据库模式更恰当,在这个环境中,要事先确定与要执行的工作相适应的数据库的逻辑分割是很难的,同时用户们又紧密地合作在一起。
