查询词典 difference group

The difference schema of the initial boundary value problem was converted to the step-by-step form,which was similar to the difference schema of the initial value problem.It is concluded that the difference schema satisfying the Von Neumann condition is a stable schema,and that,under the consistency condition,such stable schema is convergent.Moreover,with error estimate expression for the difference approximation to the classical solution,the linearity condition is unnecessary.

引入反投影算子将发展方程初边值问题的差分格式转化为与初值问题差分格式类似的逐步推进的形式，从而得出：满足Von Neumann条件的差分格式是稳定的格式；在相容条件下，差分格式若稳定(或满足VonNeumann条件)则格式收敛，且对古典解的差分逼近有误差估计式，不再需要线性的条件。

Goodbye Alice in Wonderland Jewel It's four in the afternoon I'm on a flight leaving L.A. Trying to think about my life My youth scattered along the highway Hotel rooms and headlines I've made a living with a song Just a guitar as my companion Wanting desperately to belong Fame is filled with spoiled children They grow fat on fantasy I guess that's why I'm leaving I crave reality So goodbye Alice in Wonderland Goodbye yellow brick road There is a difference between dreaming and pretending I did not find paradise It was only a reflection of my lonely mind searching For what was missing in my life I'm embarassed to say the rest is a rock and roll cliche I hit the bottom when I reached the top I never knew it was you who was breaking my heart I thought you had to love me You did not Yes a heart can hallucinate If it's completely starved for love Can even make monsters seem like Angels from above You forged my love like a weapon And turned it against me like a knife You broke my last heartstring But you opened up my eyes So goodbye Alice in Wonderland Goodbye yellow brick road There is a difference between dreaming and pretending That was not love in your eyes It was only a reflection of my lonely mind wanting what was missing in my life And growing up is not the absence of dreaming It's being able to understand the difference between the ones you can hold And the ones that you've been sold Dreaming is a good thing cause it brings new things to life Pretending is an ending that perpetuates a lie Forgetting what you are Seeing for what you've been told Well, truth is stranger than fiction And this is my chance to get it right Life is much better without all of your pretty lies So Goodbye Alice in Wonderland You can keep your yellow brick road there is a difference between dreaming and pretending There's not tears in my eyes It was only a reflection of my lonely mind searching It was only a reflection of my lonely mind finding I find what's missing in my life

再见，梦游仙境的爱丽丝下午四点我在飞离洛杉矶的班机上试着去理顺生活我的青春散落在公路上就宿于各地旅馆，无数次登上头条我以一首歌成功立足吉他为伴我强烈渴望被接受和认可有名的人大多是被宠坏的孩子幻想使我们贪求无餍我猜想这就是我离开的原因我渴望活在现实里因此再见吧，梦游仙境的爱丽丝再见吧，黄砖路梦想和矫饰不同我没有找到天堂那不过是我孤独心灵的一种反映，我渴望找到生命中缺失的东西尽管尴尬，我不得不说一句摇滚乐界的陈词滥调当我的事业达到顶峰时，我的心情跌落到了谷底我从未想过，会是你让我心碎我以为你一定会爱我但你没有是的，如果心对爱饥渴它会产生幻觉，认假为真它甚至可以把妖魔认作下凡的天使你把我的爱练成一种武器然后把它像刀子一样捅向我你断了我最后一根心弦但你让我看清了现实因此再见吧，梦游仙境的爱丽丝再见吧，黄砖路梦想和矫饰不同你眼里的不是爱不过是我孤独心灵的一种反映，我努力寻找生命中缺失的东西成长不是梦想的消失而是一种能分辨你坚守的东西与导致你被骗的东西的能力并且梦想是个好东西因为它给生命带来新鲜事物但矫饰是一个终结它使谎言无限期地延续忘了你是谁只着眼于人们告诉你的那些东西真实比虚构更奇怪而这是我求取真实的机会没有那些漂亮的谎言，生活会变得更美好因此再见吧，梦游仙境的爱丽丝你可以留住你的黄砖路梦想和矫饰不同我眼里的不是泪水不过是我孤独心灵的一种反映，我意识到不过是我孤独心灵的一种反映，我意识到我已经找到了生命中缺失的东西

In this thesis, the resonance fluorescence spectra of a A-type three-level atom is calculated, which is driven by two bichromatic fields having the same difference of the frequency. In addition, the influence of the relative phase difference on the fluorescence spectra are considered. It is found that the fluorescence spectra of the atom are deeply depend on the relative difference and the appearance and cancellation of the fluorescence are obtained by changing the relative phase difference.

First, calculates the fast moving average (usually 12 days) and slow moving average (usually 26 days) by exponential calculation method; second, make fast line value minus slow line value to gain the difference of relative distance. In order to make the trend signals more clear and less influence exerted by of excessive price fluctuation, the difference should be smoothly calculated (general elect 9 days) to get average of difference value.
