The oldest is based on the theory of purchasing - power parity ( ppp ) : the idea that, in the long run, exchange rates should equalise prices across countries ( the economist ' s big mac index is a crude version of this )
最古老的方法建立購買力平價理論（ ppp ）之上:其理念是，在長期匯率應該使各國間的價格水平相等（ 《經濟學人》的巨無霸指數就是一種粗略的版本） 。 -
It is an extreme challenge research subject for such network due to the dynamical topology change, bandwidth limitation and power constraint. the state - of - the - art of the manet technology in 5 layer : physical layer, mac layer protocols, routing protocols, transport protocol and application and middle ware issuses are summarized in this thesis. five typical routing protocols dsdv, dsr, tora, aodv and zrp are studied
本文介紹了移動自組網的起源、特徵和當前的發展狀況，並歸納了其主要的應用領域；分別從物理層、 mac層、路由層、傳輸層、中間件和應用層等5個層次分析和介紹了當前manet採用的技術和協議，尤其對路由協議（ dsdv 、 dsr 、 tora 、 aodv和zrp ）進行了詳細的研究。 -
In forth chapter, several difference methods that are suitable for solution of quasilinear equation are presented, namely, one step lax - wendroff scheme, two step lax - wendroff scheme, mac cormark scheme, tvd scheme, harten tvd scheme with two - order precision. all of them are applied to simulate the same traffic - flow question and choose the best scheme under the consideration of their results. in fifth chap ter, power function traffic - flow model and harten tvd scheme with two - order precision are applied to simulate red - green signal traffic - flow, including isolated, synchronous and synchronous changing red - green signal case
在第4章中，給出了適于求解擬線性方程的幾種差分格式，即一步lax - wendroff格式、二步lax - wendroff格式、 maccormark格式、一階tvd格式、 harten二階tvd格式，並用上述5種格式對同一簡單的交通流問題進行了數值模擬，利用數值結果，篩選出最適合求解具有強間斷特性的交通流問題harten二階tvd格式。 -
Much reference of the algorithms and models can be got from the performance results for the practical design and layout. system - level simulation of hsupa builds the integrated platform and key models to describe and simulate the common structure and features of the radio network, including cell layout, path gain, traffic model, power control, handover, etc., also the special ones of hsupa, including mac - es / e, node b controlled scheduling, harq, shorter tti, etc.
所謂hsupa系統級模擬就是要搭建系統級的模擬平臺，對無線網路的公共結構和特性（例如小區布局，傳播模型，衰落通道，天線模型，功率控制，切換， ue的分佈和移動，業務的建立終止和中斷等）和hsupa的專有結構和特性（ mac - es / e ， nodeb控制的調度， harq ，更短的tti ）進行描述和建模。 -
Abstract : the basal work principle of electric welding mac hine are introduced. the application and safeguard of power electronics device ( e xample high - power scr and igbt ) are particular introduced
文摘:介紹了焊機電源的基本工作原理，並詳細地敘述了電力電子器件（以大功率晶閘管、 igbt為例）在焊機電源中的應用和保護措施1 12 。 -
And some low power considerations in data path design and on - chip memories design have also been taken. the mac operation is essential to media processing
