  1. The great tour purchasing power is the drive power of promoting the region ' s tourism developmentln the regional space, scale economic and regional separation are one of the basic characteristics of promoting tourism industry, so we must arrange the regional tourism industry with a systematic method and give prominence to the central city. for its outstanding area in the regional space, central city has evident superiority in the regional ecnomic development, and has echelon between central city and its periphery scennic spots, which is the inducement mechanism of tourism industry ' s arranging, developing and advancing step by step. for the law of diminishing marginal utility and the theory of equilibrium, the max utility equilibrium of tourism consumption be at the point of tangency of undiscrepancy curve and the cost budget curve

    中心城市居民巨大的出遊力是拉動其周邊旅遊地發展重要的內在驅動力；由於地緣關系，區域規模經濟與地域分割並存，是旅遊產業運動的一個基本特徵，為此必須對區域旅遊經濟進行系統化布局，突出中心城市的產業中心性；因其區位條件獨特，中心城市在區域經濟發展中居於明顯的優勢，與周邊城鄉部位存在經濟發展上的梯次性，這種梯次性是區域旅遊生產力布局、產業發展梯次傳動，最終整體聯動的經濟誘導機制；根據邊際效用遞減規律和旅遊者最大效用均衡理論，旅遊消費效用最大化的均衡在無差異曲線與開支預算線的切點（即旅遊目的地選擇的最佳位置）上，且隨著邊際效用遞減，目的地選擇的最佳位置向遠離中心城市方向移動，這就是中心城市與周邊旅遊地互動關系的經濟學解釋。
  2. " for methods of analyzing economic time series with time - varying volatility arch

    所發明的「自動遞減條件下的異方差性」
  3. Because of the great temperature difference between low - temperature refrigerator and circumstance outsides, as we know, the place where there is temperature difference must have heat transferring, then in order to reduce heat loss of refrigerator during operating process, the study on low - temperature refrigerator is necessary. this article demonstrates the main problem of case design progress and gives some advice about improving the efficiency of low - temperature refrigerator by contracting different respects of case design between household refrigerator and low - temperature refrigerator

    由於低溫冰箱內部與外界環境的溫差很大，而我們知道有溫差的地方必然存在熱的傳遞，那麼為了減少冰箱在運行過程中的熱損失，對低溫冰箱箱體的設計過程的研究是有必要的。本文重點闡述了低溫冰箱箱體設計與普通冰箱箱體設計的不同之處以及低溫冰箱設計中的主要問題，並提出設計思路。
  4. It is the result of applying the system - distinguished method out of controlling theory to prediction. spurning the stationary parameter prediction model, the multiplayer - transfer method regards the predicted variable as a random, dynamic, time - changing system. it decomposes the time - changing status variable prediction into two steps : first, predicting the time - changing parameters ; second, on the basis of the first step, predicting the system status variable

    多層遞階方法摒棄了一般統計預測方法中所使用的固定參數預測模型，而將預測對象看成是隨機動態的時變系統，把時變系統的狀態預測分離成為對時變參數的預測和在此基礎上對系統狀態的預測兩部分，對時變參數的預測導致狀態預測誤差的減小。
  5. ( 4 ) only when the resistance r = l / c, the transition efficiency between electric energy and heat reach its maximum value, which makes it possible to design the high performance damping composites of multi - energy transitions by adjusting the vgcf content. cpe / zkf / vgcf composites : in the cpe / pzt / vgcf composites, the conversion efficiency from force to electricity is very low because of the obvious difference of rigidity between cpe and pzt, which leads to the damping effect of multi - energy transitions is not so evident as the viscoelasticity of the matrix cpe, especially during the cpe glass transition

    Cpe / zkf那gcf復合材料:針對cpe / pzt / vgcf復合材料中由於cpe和pzt之間模量差異較大，導致cpe和pzt之間的應力傳遞欠佳，影響力一電變換效率，從而壓電導電減振作用效果並不十分顯著的現象;本章中採用極性有機小分子雙（ 2一輕基- 3一環己基一5一甲基）一苯基]甲烷（ zkf ） ，而不採用pzt ，消除了pzt與cpe模量方面差異的影響。
