Basing on the method of approximate mechanics , the mechanical behavior and fatigue fracture characteristic of steel bridge asphalt mixture surfacing under repeated load was analyzed 摘要采用力學(xué)近似方法,對(duì)鋼橋面瀝青混合料鋪裝層在循環(huán)荷載作用下的力學(xué)行為和疲勞損傷特性進(jìn)行了理論分析。
Moreover , fc - times integrated c - semigroups provide a simple method of approximating the generalized solution space and its topology . for a given closed generator and arbitary initial value , we can not necessarily make the solution of the abstract cauchy problem or the fc - times integrated abstract cauchy problem unique 而要使-次積分抽象cauchy問(wèn)題有重要意義的一種情形就是其解是唯一的,因此我們自然會(huì)有問(wèn):什么樣的初值能讓-次積分抽象cauchy問(wèn)題的解是唯一的
In this paper , we studied the deterministic mechanism of isi with the unstable period orbit ( upo ) ; we tested many isi data from different model with the method of approximate entropy ( apen ) to study the method which is used in testing the degree of complicacy of isi and we built up a system including hardware and software for our lab to view and record action potential , firing frequency and isi in real time . results 1 . spontaneous firing patterns were observed from neurons of supraoptic nucleus ( son ) in hypothalamus with the method of patch clamp 本研究通過(guò)對(duì)大鼠視上核神經(jīng)元自發(fā)放電的非穩(wěn)定周期軌道的計(jì)算,討論了isi的確定性問(wèn)題;利用近似熵的方法對(duì)多種神經(jīng)放電的isi資料進(jìn)行了復(fù)雜度的測(cè)量,討論了這種方法在isi的復(fù)雜度測(cè)量第四軍醫(yī)大學(xué)碩士論文中的應(yīng)用;另外,還開(kāi)發(fā)出一套記錄原始放電和isi的程序,解決了采集isi的問(wèn)題。
