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.

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

With the evaluation, each group measuring value is considered as a single subsystem, and the minmax-difference, mean difference and the mean square value of each group are calculated. Then, the ratio of the mean difference to the measurement mean value is defined as the system-relatively error of subsystem and the ratio of the minmax difference to the measurement mean value is defined as the accidence-relatively error of the subsystem.

There were very significant differences about the values of MP, MPF and AEMG among the motion muscles, but there was no significant difference about the singals of MF slope, MPF slope and AEMG slope. In patients group there were significant differences about the values of MF, AEMG, AEMG slope of motion limb between paretic side and non-paretic side. There were also significant differences about the values of MPF slope between paretic side of the patients and left side of the health. But there was no significant difference about other parameters in groups or among groups. Compared the activity muscles of four groups, there were significant difference about the values of AEMG and MPF among initiative muscles, antagonistic muscles and co-contraction muscles. There were very significant differences about the values of MF and MPF among co-contraction muscles, but there was no significant difference between initiative muscle and antagonistic muscle.

In this paper, we discuss effect algebra and related topics. The main results are the following:1. Effect algebra is a commutative algebraic structure. To get a non-commutative algebraic structure.we introduced the concepts of left difference and right difference, and we also introduced the concept of the Bi-difference sets, the concept of pseudo-difference poset, and proved that pseudo-difference poset is equivalent to pseudo-effect algebra.

Soybean planted in the yellow brown soil, althongh they had big difference in nodule numbers caused by different inoculation methods, there were no difference in the fresh shoot weight because of the poor nutritional conditions. Soybean planted in the brown soil, the difference between different inoculations and fresh shoot weight were obviously because of the balance nutritional conditions. Although there were big difference in nodule numbers when soybean were planted in the peat, there were no difference in the fresh shoot weight, this might be caused by peat, the peat were not a natural soil type and the nutritional conditions might be unbalance.

Firstly, edge extracting is conducted with a laplace operator for a k frame image of fk and a k-1 frame image of fk-1 collected by a camera; secondly, difference calculus is conducted for images of two frames whose edge is extracted, and a difference image of D is obtained; thirdly, average filtering and binary processing is conducted for the difference image of D, fourthly, the image which is processed of binary is judged, i.e. when the difference of a pixel in the difference image is more than the set threshold value, the pixel is confirmed as a target pixel; otherwise, the pixel is a static background pixel.
