Chapter 2 of this paper , by using a new method of proof , we obtain the weak ergodic convergence theorem for general semigroups of asymptotically nonexpansive type semigroups in reflexive banach space . by theorem 2 . 1 of chapter 1 we get the weak ergodic convergence theorem of almost orbit for general semigroups of asymptotically nonexpansive type semigroups in reflexive banach space . by this method of proof , we give the weak ergodic convergence theorems for right reversible semigroups . by theorem 2 . 1 of chapter l , we generalize the result to almost orbit case . so we can remove a key supposition that almost orbit is almost asymptotically isometric . it includes all commutative semigroups cases . baillon [ 8 ] , hirano and takahashi [ 9 ] gave nonlinear retraction theorems for nonexpansive semigroups . recently mizoguchi and takahashi [ 10 ] proved a nonlinear ergodic retraction theorem for lipschitzian semigroups . hirano and kido and takahashi [ 11 ] , hirano [ 12 ] gave nonlinear retraction theorems for nonexpansive mappings in uniformly convex banach spaces with frechet differentiable norm . . in 1997 , li and ma [ 16 ] proved the ergodic retraction theorem for general semitopological semigroups in hilbert space without the conditions that the domain is closed and convex , which greatly extended the fields of applications of ergodic theory . chapter 2 of this paper , we obtain the ergodic retraction theorem for general semigroups and almost orbits of asymptotically nonexpansive type semigroups in reflexive banach spaces . and we give the ergodic retraction theorem for almost orbits of right reversible semitopological semigroups 近年來， bruck [ 5 ] ， reich [ 6 ] ， oka [ 7 ]等在具frechet可微范數的一致凸banach空間中給出了非擴張及漸近非擴張映射及半群的遍歷收斂定理。 li和ma [ 13 ]在具frechet可微范數的自反banach空間中給出了一般交換漸近非擴張型拓撲半群的遍歷收斂定理，這是一個重大突破。本文第二章用一種新的證明方法在自反banach空間中，研究了揚州大學碩士學位論文2一般半群上的( r )類漸近非擴張型半群的弱遍歷收斂定理，即:定理3 . 1設x是具性質( f )的實自反banach空間， c是x的非空有界閉凸子集， g為含單位元的一般半群， s =仕工， 。

( 4 ) we construct the concepts of stratified approximations and base in an l - fuzzy domain , and define uniformly continuous l - fuzzy domain and algebraic l - fuzzy domain by means of the concept of base for l - fuzzy domain , prove that they are generalizations of ordinary continuous domain and algebraic domain , when l is a completely distributive lattice in which 1 is a molecule and the minimal mapping on l preserves finite meet , the stratified approximation relations on a continuous l - fuzzy domain satisfy the property of stratified interpolations , and is consist of a base for the generalized scott topology on a continuous l - fuzzy domain ( x , e ) , and every continuous l - fuzzy domain can be seen as an l - fuzzy scott continuous retraction of some algebraic l - fuzzy domain ( 4 )在l - fuzzydomain中引進層次逼近和基的概念，用統一的基的方法定義了連續l - fuzzydomain和代數l - fuzzydomain ，證明了它們分別是通常的連續domain和代數domain的推廣。當l是1為分子的完全分配格，并且其上的極小映射保有限交時，證明了連續l - fuzzydomain上的層次逼近關系滿足層次插值性質，構成連續l - fuzzydomain ( x ， e )上廣義scott拓撲的基，以及任意的連續l - fuzzydomain都可以作為某代數l - fuzzydomain的l - fuzzyscott連續收縮。

This was due to three reasons : ( 1 ) baso4 particles were rigid inorganic particles , which could hinder the retraction of polymer molecules and decreased the elasticity . ( 2 ) a bad compatibility between baso4 and tpu , small interface adhesive force and the phase interface ready to separate . ( 3 ) during high content of baso4 , the tenacity of filament mainly depended on tpu , so that the strength decreased with the content of tpu in filament down 這是因為： baso _ 4屬于剛性粒子，阻礙tpu大分子鏈的回縮，降低了纖維的彈性； baso _ 4與tpu相容性極差，共混時容易形成相界面，界面結合力小，受外力作用時相與相間容易發生分離，使纖維的力學性能下降； baso _ 4在高含量下，纖維強度主要由聚合物的力學性能決定，隨著baso4含量的增加， tpu所占比例下降，從而在宏觀上表現出纖維的力學性能下降。

Through the research of the tension in vivo , the immediate retraction rate and histology examination about the different ways and different maintaining , we get : the increase area of the rapid and conventional expansion has little difference with the expanded time ; however it has significant difference with the maintaining time . it shows that shortening the expanded time is feasible in clinic , but shortening the maintaining time is out of the question ; after the capsule is removed , immediate retraction rate of the expanded skin notably decreased , significantly different from those with intact capsule ; the collagen content of the rapid expansion is just the same as the conventional expansion , but the changes of the histology dependences on the maintaining time . comparison with conventional expansion , rapid expansion has no significant drawback ; maintaining a period after expansion can greatly increase the area of expanded skin and reduce immediate retraction 通過對不同擴張期、不同方式和不同維持期對擴張皮膚的在體張力、即時回縮和皮膚組織學的研究，得到：快速擴張和常規擴張最后獲取的皮瓣，面北京工業大學工學博士學位論文一積增加差別不大；擴張皮膚的面積增加和張力下降與維持期的長短有關；而與擴張期的長短關系不大，說明在皮膚擴張術中可以縮短注水時間，但是維持時間不能縮短；擴張皮膚去除包膜后的即時回縮率下降，與未去除包膜的相比較有明顯差異；快速擴張皮膚的膠原含量變化與常規擴張的基本一致，擴張皮膚的組織學變化與維持期的關系較為密切，與擴張方式關系不大；快速擴張和常規擴張相比，快速擴張沒有明顯的破壞作用；擴張結束后，維持一段時間，能有效的提高擴張面積且能有效地減少回縮。

Moreover , according to the performance analysis , a dynamic modify lookahead algorithm is presented to solve the problem of impaction of lookahead on system performance . a dynamic execution rate regulation algorithm is presented to reduce the retraction rate for optimistic federate . the test result showed that these two algorithms could improve system performance 考慮到時間管理部分對邦元程序性能的影響，本文還針對保守邦元中lookahead的設置對系統性能的影響，提出了lookahead的動態修正算法；針對影響樂觀邦元性能的關鍵因素，提出了動態調整邦元執行速度的算法來控制回卷概率。

Be located in bone of mid the upper jaw , before having possibly also dash forward or the deformation of retraction , also can do through the operation according to the circumstance a few adjust , change its pattern 位于面中部的上頜骨，也可能有前突或者后縮的畸形，也可以根據情況通過手術做一些調整，改變其形態。

What s more , once the afae measurements are complete , shutter release time lag is a virtually imperceptible 0 . 03 seconds . another boost to overall speed is a lens retraction time of just 0 . 6 seconds 03秒后釋放，快門時滯極短實在令人難以察覺，讓您可以毫無間斷地進行拍攝。此外，相機的鏡頭伸縮時間亦只不過是0

During such process culture plays a kind of power which is built up upon the economy and social structure and reflects them , but it also has the retraction as an independent power 在這一過程中，文化作為一種力量，它建立在經濟和社會結構基礎之上并反映其特性，但文化自身的獨立性又反作用于社會結構。

Whereas many taildraggers can afford to use non - retracting gear with minimal impact on performance , planes with nosewheels almost always require retraction mechanisms to reduce drag 另一方面，固定式后三點起落架耐沖擊性能較強。而前三點起落架，需要收放式以減小飛行時的阻力。

Despite this , let me predict the number of retractions , apologies , and so on , in tomorrow ' s newspapers and on the sites . not one . nada . zip 盡管如此，我們倒可以預測一下明天各大媒體的反應。有幾家媒體會撤消他們的報道,有幾家媒體會作出道歉？我猜，一家也不會有。

The careless , half - humorous shrug thus hears a visual affinity to the nod or bow of submissiveness and also to a turtle ' s retraction of its head into its shell 因此，漫不經心、略帶幽默的聳肩看起來和點頭表示順從有些想象，也好像烏龜把頭縮進殼里的動作。

The coverboard is fitted with a brush so that during retraction larger debris ( leaves and twigs ) is removed from the cover by the brush integrated into the coverboard 內置的篷布清潔刷，在每次遮陽篷收起時自動清潔篷布表面積存少量樹葉樹枝等雜物。
