inverse limit 中文意思是什麼
inverse limit
解釋
逆向極限-
Let x is the limit of the inverse system. suppose each projection is an open and onto map. and x is - paracompact. if each x is normal mesocompact, then x is mesocompact. moreover, we obtain the analogous result for hereditarily normal and hereditarily mesocompact properties
| = ，假設每個投射_ ： x x _是開的且到上的。 x是-仿緊的，如果每個x _為正規中緊的，則x是正規中緊的，進一步得到關于遺傳正規且遺傳中緊空間的結論。 -
Are there similar characterizations for the countable paracompact ( mesocompact, metacompact ) space and hereditarily mesocompact space ? in this paper, on the basis of the aboves, we obtain some results about them. and the product properties of mesocompact spaces and hereditarily mesocompact spaces have been paid attention. but there is no good result about them. in this paper we obtain a result about the limit of the inverse system of a normal mesocompact space and a hereditarily normal and hereditarily mesocompact space
那末，可數仿緊（中緊、亞緊）空間及遺傳中緊空間是否具有類似junnila的刻畫呢?本文圍繞這個問題在上述結果的基礎上證明了一些結果。另外，中緊空間和遺傳中緊空間的可乘性問題一直受到人們的關注，但還沒有好的結果，本文證明了一個關于正規中緊空間及遺傳正規且遺傳中緊空間的逆極限的結果。 -
Abstract : direct limit and inverse limit are the methods producing new algebra in universal algebra. in order to further study the production of the new algebra, authors define the family of duplicate set and duplicate limit, discuss the algebraic duplicate limit, the characterestics of the once more duplicate direct set and more duplicate direct limit, the family of once more duplicate direct direct algebra and the limit of once more duplicate algebraic set family

極限存在準則及其反命題 -
The inverse operator method has much advantage, such as high degree of accuracy, little limit ability to solve strong nonlinear problem and so on
該方法具有精度高、限制少、能夠解決強非線性問題等優點。本文還建立了一類普朗特邊界層問題的數學模型。 -
And about a given property p which satisfies some conditions, we give a condition for the open sets in the tychnoff product of two spaces which have a open refinement having the property p. the last chapter obtains a result about the limit of the inverse system of a normal mesocompact space and a hereditar ily normal and hereditarily mesocompact space
而且給出了，對滿足一定條件的某種性質p ，兩個空間的乘積中的每個開集族有p性質的開加細的一個充分條件。第四章詳細證明了關于正規中緊空間及遺傳正規且遺傳中緊空間的逆極限的一個結果。 -
Inverse compton limit
逆康普頓極限 -
The sizing method based on fraunhofer diffraction is limited. because of the limitation of size parameter a ? 1 and size of photodetector, it ca n ' t measure the particles less than 5 microns accurately. to extending lower limit of measurement, inverse - fourier - transform technique is discussed
利用夫朗和費衍射理論時對粒子的界定要求尺寸參數a 1 ，又加上光電探測元件的尺寸受到限制，故不能準確地測量5微米以下的顆粒，為此必需擴大測量下限。 -
The present paper shows that a class of continuous maps on circles which is extensiver than expand maps is topological stable. and its inverse limit systems are expansive
摘要討論圓周上一類比擴張映射更廣泛的連續映射，證明這種映射是拓撲穩定的， ?且其逆極限系統是可擴的。 -
For this reason, the paper is aimed at the electro - hydraulic servo - system nonlinear problem, and proposes the feedback linearity means ( that is the inverse system method ) against the system mode systematically to transform such nonlinearity into the pseudo linear system. the system mode not merely continues to have system message completely feedback the linearity means, but also achieves the great limit linearization of controlled device, for designing the controller to advance system dynamic characteristic and performance index and supply the ideal terrace in the interest of the application linearity control theory
為此，本文針對該非線性問題，提出了逆系統狀態反饋線性化方法，將其非線性系統轉化成偽線性系統，不僅完全保留了系統的信息，而且還實現了被控對象的大范圍線性化，為應用線性控制理論去設計控制器為提高系統的動態特性和性能指標提供了理想的平臺。 -
