然而現階段我國在農地整理的研究上還存在一些不足之處：一是這方面的理論研究與實踐探索目前還主要集中在北方平原地區，對南方丘陵地區的農地整理規劃設計探討得比較少；二是在當前我國農地整理項目規劃設計的實踐中還普遍存在一些問題，大多數地區農地整理目標仍主要是擴大耕地數量，補償因非農建設佔用的耕地，尚未進入以項目分析為基礎，以土地資源的可持續利用為目標的階段，一些反映近期經濟效益的喜人的「正數增長」後面，往往掩蓋著長遠的生態效益、社會效益和經濟效益等方面的「負數增長」 。We propose the joint filterbank precoders and decision feedback equalizers structure at first, by which the dispersive channel is equivallent into parallel independent flat fading subchannels such that the diversity gain of the receiver is increased. then we adopt the discrete - time ( dt ) canonical model to convert the problem of blind signal processing of tv dispersive channels into processing the time - invariant multi - channels model blindly, and discuss the problem of blind equalization and identification of tv dispersive channels based on this new model

如在改革開放初期，在產品市場需求旺盛和信貸市場預算軟約束的情況下，各類企業的最優決策就是採用高負債、高擴張的「負債的有限責任效應」策略來搶占市場並獲得高回報； 1989年以後，需求增速開始放緩，面臨產品市場產業集中度較低和信貸市場「信貸緊縮-不良貸款」循環陷阱導致的中小企業資金緊張的局面， 「錢袋鼓鼓」的優勢企業（尤其是那些可以通過股票市場融通資金的上市公司）紛紛採用掠奪性定價策略，試圖通過把中小企業擠出市場來擴大市場份額並獲得高收益； 1998年以後，產品市場和信貸市場形成了通貨緊縮和銀行「惜貸」惡性循環的狀況。產品市場上部分行業生產能力嚴重過剩，且由於體制等原因導致虧損企業無法退出，因此這些行業中出現了過度競爭的現象，企業總體收益的不斷下滑、負債率不斷提高以及銀行不良資產率的持續上升，又進一步加強了通貨緊縮和銀行「惜貸」的惡性循環。By utilizing the knowledge of digital circuit and simulation circuit, the system designs the pretreatment dealing circuit of the myoelectrical signal, which has the feature of big input impedance well suppress of public module and high gains. then the signal is gathered with " zhentong " data gathering after dealing with, and the software of signal processing is explored before the myoelectric signal is analyzed. after picking up eigenvalue, it is proved that the result is unanimous basically with the data of the relevant materials ; the other is to control artificial hand by the eigenvalue of the myoelectric signa l and at last the system gets very good control results

政府采購制度改革是我國公共財政改革的重要組成部分，引入我國從試點到推廣實施僅有十年的時間，卻取得了巨大的進展， 《政府采購法》在2003年1月開始實施后，我國採用集中采購與分散采購相結合的政府采購方式，開始了我國政府采購的集中化趨勢進程，從早期分散采購演變為大批量的集中的采購方式，當然，小批量分散采購也結合其中，列入政府集中采購目錄的物資種類與采購數量大大增加，取得了巨大的進展，卻也存在著不少的問題，具體表現為政府采購過程中出現的各種操作性問題和政府采購制度推進的障礙，以及政府采購的環境效益問題，操作性問題和政府采購制度推進的障礙問題本質上可歸納為兩方面，即內在因素，這是事前性的，偏重於制度性、體制性等根本問題;外在因素，這是管理操作層面的因素，政府采購的環境效益問題是由政府是否采購綠色產品，推動綠色產品在社會的使用而引出的，於是，對政府采購集中化趨勢中所暴露出的問題進行分析，找出問題的根源以探尋解決的思路及對策就顯得尤為急迫。分享友人
