The main contents and achievements are articulated as follows : ( 1 ) problem solving in conceptual design in virtual enterprises the features and cause of ill structure of conceptual design problem have been analyzed . the representation of design state , including product specification and fbs framework , the methods and features of design decision , and problem solving based on knowledge in conceptual design stage are studied . based on the above work , it is pointed out that the cause of ill structure of design problem lies in the absence of knowledge for decision - making in the initial stage of design , and that capturing the knowledge for conceptual design decision is an effective method for reducing the degree of structural illness 本文就虛擬企業中概念設計問題求解、概念設計信息建模、概念設計知識的獲取以及概念設計決策知識的捕捉和集成這幾方面進行了深入系統的研究,主要研究內容和成果包括: ( 1 )虛擬企業基于知識的概念設計問題求解分析了概念設計問題病態結構的特點以及產生的原因,研究了概念設計狀態(產品規范和fbs框架)的表示、概念設計決策的方法和特點以及基于知識的概念設計問題求解,指出造成設計問題結構病態化的原因是在設計的早期階段設計決策知識的缺乏,提出捕捉概念設計決策知識是降低概念設計問題結構病態程度的有效方法。

In addition , we designed a test : the midgut was removed from spodoptera exigua larvae and was cut longitudinally into halves , the midgut epithelia were cleaned and digested with dispase ii , the pelleted cells in grace medium with 7 % fbs supplemented with 100units / ml penicillin , 100ug / ml streptomycin were cooled and then suspended in r18 - labelled virus 實驗結果表明,在幼蟲的病毒接種物中添加合適濃度的熒光增白劑( 0 . 01g . ml一’ )不會改變病毒在幼蟲中腸組織中的感染部位,卻可以提高幼蟲對病毒的敏感性,增加了病毒毒力。

In the fourth chapter , colored petri net ( cpn ) models of fbs are constructed , and through which the internal procedure of fbs and the relationship of mode and parameter status between different fbs are analyzed for preparation . in the fifth chapter , we discuss the development of function block application process 第四章介紹了一種有效的復雜系統分析模型? ?功能塊的著色petri網( cpn )模型,為后面的功能塊實現中的參數狀態傳播和模式切換部分做下技術準備。

This dissertation is trying to break through the boundaries of the traditional division by systematically investigating fbs , an issue of great practical and academic significance , from the angles of economics , sociology and biology 論文嘗試突破傳統學科分工的藩籬,從經濟學、社會學和生物學結合的視野,對這個具有強烈現實意義和重大學術價值的課題進行較為系統的專門研究。

Methods isolation , , culture and purification of mouse mscs mmscs were isolated from the femurs of adult mice four weeks old and propagated in vitro . mmscs were originally cultured in dmem - lg with 10 % fbs , 100u / ml penicillion , 100mg / ml streptomycin 在細胞沉淀中加人含10胎牛血清的dmem lg培養基,計數細胞數,調整細胞密度,按3x10vinl接種于25cm ‘的玻璃培養瓶中。

After being cultured three generations and depleted feeder cell layers , the es - d3 cells differentiated into ebs efficiently in the culture media supplemented with homemade green season fbs and - me in petriperm bacterial - culture dish 二、 inbmec cm誘導小鼠es細胞生成造血干祖細胞將獲得的4debs制成單細胞懸液,加入inbmec cm誘導4debs的單細胞生成造血干祖細胞。

Chapter 3 discusses entrepreneurs in fbs as the personal representatives . they progress in developing their human capital , physical capital , and social capital , which this thesis calls the three - dimensional development mechanisms of entrepreneurs 第三章,家族企業家作為家族企業人格化,其成長是基于人力資本、物質資本和社會資本三維機制的一個動態過程。

The clonies of es cells were flatter on the mitomycin c - inhibited sto fibroblasts , not easily differentiated from the feeder layer cells surround them , than that on the mef in dmem supplemented 15 % fbs . 5 以sto細胞作飼養層,添加15 fbs ,在倒置顯微鏡下觀察, es - d3細胞不易與周圍的sto飼養層細胞區別,形成的集落較平坦,生長狀態不如mef飼養層好。

Although modern economics has absorbed nutrients from other branches of social sciences and developed many new research areas , there are fewer literatures for analyzing the phenomena of fbs more comprehensively 雖然現代經濟學不斷吸收其它學科營養,拓寬新的研究領域,但至今對家族企業進行系統全面分析的文獻并不多見。

Why have most of the newly emerging enterprises during the economic transition in china been family businesses ( fbs ) ? why are fbs still the dominant form of economic organization in the world 為什么在轉軌期間中國新興的民營企業大都是家族企業,而且,在世界范圍內家族企業也普遍存在、持久不衰

The concentration of fbs ( fetal bovine serum ) and ncs ( newborn calf serum ) was influential on the culture process of mef ( mouse embryonic fibroblast ) and es cells 血清濃度的高低對胎鼠成纖維細胞和es細胞的培養過程是有影響的。無血清或低濃度的血清能抑制細胞分裂增殖,使細胞生長出現停滯。

In the later experiments dmem - lg / 20 % fbs / bfgf ( 50ng / ml ) was used as the neuronal preinduction media and dmem - lg / atra ( 150mg / ml ) was used as the neuronal induction media 在以后的實驗中, bfgf矚0n才rnl )被用來作為前誘導劑,人ttiho50略inl )被用來作為誘導劑。

The numhers of day - 4 ebs per milliliter culture media are 44 . 83 1 . 22 ( n = 6 ) and 43 . 17 1 . 05 ( n = 6 ) respectively when cultured by hyclone fbs and homemade green season fbs 在含進口hyclone胎牛血清或國產四季青胎牛血清的培養液中培養, es d3細胞形成的4debs數量分另為44

Through building functional , behavioral , and structural model , formal representation of function , behavior , and structure in fbs framework is realized 通過建立功能模型、行為模型和結構模型,實現了fbs框架中功能、行為和結構的形式化表示。
