PCM+“短接法”在站场埋地管道定位中的应用

为了实现站场内埋地管道的非开挖定位,借鉴长输管道定位技术,采用PCM+探索实现站内管道定位的方法。站场内管道错综复杂,用电设备干扰大,按照正常信号加载方式,电流信号在埋地管道和用电设备之间无序流动,无法实现目标管道准确定位。采用PCM+"短接法",用金属导线将发射机与待检埋地管道直接相连,不经过地网,而形成"发射机-导线-管道-导线-发射机"的封闭回路,接收机可准确探测到埋地管道的位置,现场试验效果良好,经开挖验证后发现误差小于100 mm。

Analysis Method of External Traffic Demand in City Area

To overcome the disadvantages of the existing method, a “dual four-stage” method” is put forward to analyze external traffic demand in city area considering the characteristics of external traffic. The method is carried out by two steps, and in the first step the city area is regarded as an overall traffic zone and the “four-stage” method of regional traffic demand analysis is used to obtain the total generation volumes of internal-external (IE) & external-internal (EI) trips of city area as well as the traffic volumes of both directions of all the arterial highways through the city in planning years. In the second step, the planning area of city is divided into several parts as internal traffic zones, and the external traffic zones are set near the junctions of highways and cordon line, then the “four-stage” method is applied for the second time to obtain the trip generation and distribution of IE & EI trips and (external-external) EE trips for internal traffic zones and external traffic zones in planning years. The application of the analysis on external traffic demand for comprehensive transportation planning of Zhenjiang City shows that the proposed method combines the advantages of influence area method and Cordon Line method it overcomes disadvantages of the two methods, and the results are more consistent with the real situation.     

Response of the Black Sea mean level to atmospheric pressure and wind forcing

The response of the Black Sea mean level to atmospheric pressure (AP) and wind forcing is investigated using 5 years of TOPEX/POSEIDON (T/P hereafter) data. A coherence analysis is first applied to mean sea level and pressure to examine the validity of the inverse barometer (IB) approximation over this area. As expected, it reveals very significant deviations from an IB response attributed to the narrowness of the Bosphorus Strait and its limiting role in water exchanges. A comparison is drawn with the Mediterranean Sea case. A single basin version of the Candela analytical model [Candela, J., 1991. The Gibraltar Strait and its role in the dynamics of the Mediterranean Sea. Dyn. Atmos. Oceans 15, 267–300], which takes linear friction at the strait into account, is then used. The model explains a significant part of the T/P mean sea level variance (about 30%, while the IB correction only explains 5% of its variance) and provides a means to correct the altimeter data for the pressure effect much better than the standard IB effect. The response of the mean sea level to wind forcing is then analysed. Coherence analysis between sea level and along-strait wind stress (WS) reveals a significant coherence at periods ranging from 40 to 100 days, with an almost steady phase of 270°. This result is confirmed with a multiple coherence analysis (mean sea level vs. WS and AP). A plausible mechanism is a piling-up of water at the northern or southern end of the strait due to along-strait wind forcing. The associated along-strait pressure gradient would modify the barotropic flow in the strait and then the mean sea level. Using an extension of the Candela model, we show that this mechanism is consistent with T/P mean sea level observations.     

“双元制”模式教学研究初探

近些年来,我国引进德国"双元制"教学模式,使得我国汽车专业学校和企业的合作更上一层楼,因此对"双元制"职业教学模式结果的研究也在社会上引起关注。从三个方面来进行探究,分别是分析"双元制"职教发展概况,只有先了解什么是"双元制"、它发展如何,才能进一步熟知它的教学模式,二是德国"双元制"对我国高等职业教育发展的启发和作用,这是重中之重。三是德国"双元制"在汽车专业中的实践运用,引入一种模式之后必然在实践运用中才能证明是否正确。
