Based on the review of and comment on the concepts and theories of attitude and travel attitude and the current research situations about travel attitude, according to three element theories of the attitude, by way of random sampling of strata, the paper has carried on measurement of travel attitude of zhengzhou city, wuzhi county and yuanyang county resident. in writing this paper, the author designed a travel attitude inventory, which had been proved to be of good reliability and validity. then it carries on factor analysis and cluster ' s analysis to the measurement
本研究在對態度、旅遊態度的概念、理論和旅遊態度的研究現狀進行述評的基礎上，依據態度的三元素理論，採用經過信度、效度檢驗的自編旅遊態度問卷，以分層隨機抽樣的方式，對鄭州市、武陟縣和原陽縣居民的旅遊態度進行了測量，並對測量數據進行因素分析和聚類分析。 -
Abstract : considering the characteristic of mixed traffic in chinese cityies, and the different given conditions, the author develops combinatorial mathematical programming models involving travel choice / destination choice / mode choice / route choice on the basis of symmetrical deterrence and presents the proof that the optimal solutions satisfy the random choice conditions
文摘:考慮到我國城市混合交通擁擠的特點，針對不同的條件，作者給出了基於對稱阻抗的出行、訖點、方式和路徑隨機選擇的綜合模型，並證明該模型的最優解能滿足出行、訖點、方式和路徑隨機選擇的要求。 -
Platen backhaul height can be set in a random manner, therefore reducing the spare travel
壓板回程高度可任意設定，減少了空行程。 -
Standard shortest path algorithms ( such as the dijkstra algorithm ) are not valid, since travel times are random, time - dependent variables. especially, the recognition version of the stochastic shortest path problems is np - complete. k expected shortest paths problem shown in this paper is one of these problems
傳統的最短路徑方法不能解決這種非線性路徑耗費的路徑問題，尤其是同時具有隨機性和時間依賴性的網路使得最優路徑問題成為np完全問題，本文研究的k期望最短路徑就是這樣的問題之一。 -
Numerical simulation and auto - generation of random fissures network are conducted by monte carlo method. secondly, one - side immersion swelling tests are carried out, and time - travel expansive process regulations are obtained
然後，進行了非飽和膨脹土的單向浸水膨脹試驗，研究得出了單向浸水條件下非飽和膨脹土的膨脹變形隨時間發展的規律。 -
It has the following four features : 1. reduce starting and stopping impact, travel smoothly ; 2. the lifting speed can be designed at random in the range of 1 / 8 rated speed ; 3. to improve work efficiency, the lifting speed with no load can be set at random between the rated speed and 1. 5 times the rated speed ; 4. to change the frequency of the motor through transducer and make the motor work with slow speed in order to improve its site accurateness
該產品具有以下四個特點： 1 .能減小啟動、停止時的沖擊，具有平穩運行的性能； 2 .能按需求設定起升速度，可在1 / 8額定速度之間隨意設定； 3 .能提高工作效率，在空載下，起升速度可在額定速度到1 . 5倍額定速度之間設定； 4 .可以通過變頻器對運行電動機進行變頻控制，從而使運行電動機微速運行，提高運行定位的準確性，還可以進行點動操作。 -
It is a time - dependent model. it was introduced by hammersley and welsh in 1965. it mainly studies the property of vertex set to which from one certain point during some given time, under conditions that the network of the path has been given. but the travel time of the path is random
它主要研究當路的網路已經給定，但路的通過時間為隨機的情況下，從某一固定點出發，在給定的時間內能夠到達的點的集合的性質。
