We give the detail analysis and show that the system exhibits subcritical pitchfork bifurcation, supercritical pitchfork bifurcation and transcritical bifurcation in the different regimes of control parameters,we also give the condition of the occurrence of bifurcation from the trivial solution,and consider the bifurcation directions.

其次，以前的研究工作主要是针对反应项是纯粹的二次项(p=0)或纯粹的三次项(p=1)的反应扩散系统。本文中取p∈[0，1]为参数，得到了比Auchmuty等人的工作更丰富的结论。

To explain the computable of correlated noise attenuation by wavelet analysis; to give adaptive wavelet shrinkage algorithm on basis of threshold. We discuss three thresholds'choice; namely eigenvalue, unbiased risk estimator and hitograph method. We give comesponding experiments'analysis and comparison. It shows that our method is reliable.

阐述了小波分析去相关噪声的可行性；给出了基于阀值的自适应小波收缩法，讨论了三种阀值的选取；论述了特征值法，无偏的风险估计与直方图法，给出了相应的实验分析与比较，说明了该方法是可行的。

According to the passage, which of the following is TRUE?A. In Thailand people give fish and birds to the birthdays person as presents.B. In Holland people give presents to unbirthday persons.C. In Nigeria people who were born in the same period may celebrate their birthdays on the same day.

答案： B 由第八段可知，在泰国给过生日的人买活的鱼和鸟让他释放它们，以此带来好运，故选项 A 不正确；由第五段可知，在荷兰过生日的人得到礼物的同时，也送给不过生日的人礼物，故选项 B 正确；由倒数第二段可知，在尼日利亚，同岁的人在同一天集体庆祝生日，并不是出生于同一天的人集体庆祝生日，故选项 C 不正确；由第八段的"In Thailand， two tall candles are lighted the night before a birthday。"

Every-where is the unspecialized motorist whose recreation is mileage, who has run the gamut of the National Parks in one summer ,and now is headed for Mexico City and points south.Lastly ,there is the professional ,strivinig through countless conservation organizations to give the nature-seeking public what it wants ,or to make it want what he has go give.Why, it may be asked , should such a diversity of folk be bracketed in a single category?Because each, in his own way, is a hunter. And why does each call himself a conservationist?

这通常会被我们冠上"考察、学习、观光"等名堂，我们不谈文化景点的环保工作，我们更多要谈这种需求来源于哪里，走千里路的前提是已读万卷书才知道走千里路好，在文化旅行前，我们读万卷书了吗，事实上，我们到那里只是单纯地感受一下异地风情和教科书上早就有的描述，比如西安兵马俑，少数民族的风情万种。

In the process of analytical solution, the divergent item can be give up according to the physical meaning of the solution. But there is no chance to give up the divergent item in the step-by-step integration method. This is why the numerical solution is unstable.

在比较了含有此发散项的该通解的数值结果与平均常加速度法的计算结果后，发现它们是一致的，从而找到了逐步积分法不稳定的原因，即逐步积分法不能避开方程解集中的不稳定子集（从而导致了一种发散性的不稳定）。

His information is therefore largely unverified and based on this he will give you a pre-qualification verbally or give you a letter to that effect, subject to a variety of conditions.

因此，他的情报主要是核实并在此基础上，他会给你一个预审或口头给你信件说，受各种条件。

Via comprehensive computations, the possibilities of vinylidene and allene intermediates were excluded, and the reaction mechanism was found to contain the following three steps:(1) gold-catalyzed cyclization to give the cyclic intermediate,(2) the cyclic intermediate undergoing a 1,3-H migration to give a more stable intermediate, with the assistance of water-cluster,(3) finially, the 1,2-H or 1,2-silyl migration occuring for generation of the observed product.

通过对各种可能的反应路径的进行计算和比较，排除了亚甲基卡宾和连二烯中间体的可能性，并确定该异构化反应机理包含以下三个步骤：（1）炔丙基吡啶反应在金催化条件下发生分子内的成环得到环状中间体；（2）环状中间体在水分子簇的协助下优先发生1，3-氢迁移反应，异构化得到更为稳定的中间体；（3）最后再进行1，2-氢迁移或是1，2-硅烷基团迁移即得到实验中所观察到的环异构化产物。

Celine Dion: I Surrender (Louis Biancaniello/Sam Watters) There's so much life I've left to live And this fire's burning still When I watch you look at me I think I could find a way To stand for every dream And forsake this solid ground And give up this fear within Of what would happen if they end, you I'm in love with you 'Cause I'd surrender everything To feel the chance, to live again I reach to you I know you can feel it too We'd make it through A thousand dreams I still believe I'd make you give them all to me I'd hold you in my arms and never let go I surrender I know I can't survive another night away from you You're the reason I go on And now I need to live the truth Right now, there's no better time From this fear, I will break free And I'll live again with love And know they can't take that away from me And they will see...
