    盡管國內外經濟和人口學方面的專家與學者很早就開始了對農村勞力問題的研究並取得了極大的進展,但是,我國在研究農村勞力問題時,基於三點:其一,我國國情決定了國外的理論例如劉易斯理論,雖然對研究我國的農村勞力問題具有指導意義,但卻不能照搬這些理論;其二,從國內看,我國對該問題的研究重定性分析而定量分析明顯不足;其三,缺乏對我國占國土面積69 、人口56的山區農村這一特殊區域內的勞力開發利用及轉的專門性研究。為了彌補這三個缺憾,論文採用經濟計量學的數量分析方,利用實際調查資料,藉助tsp軟體,建立了以外出勞力數量為被解釋變量,城市化率、農村產業結構、城鄉收入距、農村社會基礎設施建設、農村勞力素質以及人口自然增長率六個變量為解釋變量的模型,通過對該模型進行經濟學、統計學、經濟計量學三個方面的檢驗,得出如下結果:城鄉收入距和城市化率是影響山區農村勞力開發利用及轉的最重要的兩個因素;農村社會基礎設施建設和農村勞力素質是較為重要的兩個影響因素;而農村產業結構和人口自然增長率相對來說是較不顯著的影響因素。據此,本文提出了在研究山區農村勞力開發利用及轉問題時,應慎重對待城鄉收入距、城市化水平、農村勞力素質、農村產業結構、農業機械化五個問題。

  4. In 3g communication system, the most promising location method was the locating arithmetic based on the time of arrival and the time difference of arrival ( toa / tdoa ) of signal, or the angle of arrival of signal ( aoa ). however, either the arithmetic based on toa or that based on aoa was badly affected by the none line of sight ( nlos ) phenomenon

    在第三代通信系統中,最有前景的定位方式是基於信號到來時間/時間( toa / tdoa )或信號到來角( aoa )的定位演算。但不管是基於信號到來時間的演算還是基於信號到來角度的演算,定位信號的非距傳播效應( nlos )都會對其造成嚴重的影響,在影響定位精度的諸多因素中nlos效應被公認為是最主要的因素。
  5. Considering the stability and continuity of face region, and the error propagation effect due to the high error rate in wireless channels, the intra - refresh method is used. the redundant data is not too much owing to the continuity, and the error propagation effect can be stopped accordingly

In cellular envirorunents, because of the influence of several adverse factors, such as muitipath, non - line - of sight propagation, noise, interference and channel frequency characteristics, radio statistics measuremenis like tdoa, toa and aoa related to mobile position, the performance of location algorithms mny be significantly degraded and the position estimation of ms is inevitably biased

    在蜂窩網路環境中,由於受多徑、非距傳播、噪聲、干擾和通道頻率特性等多種不利因素的綜合影響,使tdoa 、 toa 、 aoa等與臺位置有關的電波特徵測量值不可避免地出現較大誤,從而使各種定位演算的性能顯著下降,造成臺位置估計出現較大偏
  7. At first, by using the feature that the excess delays of nlos propagation follow the exponential distribution, the los propagation parameters are reconstructed and the toa parameters measured from all bs are preprocessed. then, the ms ' s position is estimated by the los locating algorithm with the preprocessed data. finally, to mitigate the effect of the errors in reconstructed parameters, the estimated results are smoothed

    首先,利用非距傳播時延服從指數分佈的特點,對不同基站一次測量的數據進行預處理,重構距傳輸參量;然後,對處理后的數據採用距定位演算估計臺位置;最後,對估計結果進行平滑后處理,以減小重構出的參量誤的影響,進一步提高定位精度。
