Estimation precision of Displaced Phase Center Algorithm(DPCA) is affected by the number of displaced phase center pairs,the bandwidth of transmitting signal and many other factors.Detailed analysis i
任何一种技术,从单纯的案例研究到真正在生产领域应用还有很长一段路。赵传佳制定出的关于物流信息系统评价指标体系很受公司领导层的重视。很快他就有了新的任务。
家电生产作为一个非常复杂的供应链,会有很多的应用RFID场合与方式。但由于每个企业的情况不同,具体需求可能也不一样。
以青岛海域浒苔藻体中光合活性较强的青岛奥帆基地A赛区南侧海域水表漂浮藻体和团岛湾海域的泥表沉降藻体为研究对象,通过叶绿素荧光技术配合氧电极技术研究了它们的光合作用情况.结果表明,虽然漂浮藻体光合活性较强,但潜在光合活性明显低于正常值,而泥表藻体的光合活性极弱,表明目前该海域的漂浮浒苔藻体已受到了较严重的环境胁迫,泥表藻体已经死亡或正处于死亡的边缘.另一方面,实验室培养的结果表明,团岛湾海域中沉降至
Coseismic water level changes which may have been induced by the Wenchuan MS8.0 earthquake and its 15 larger aftershocks(MS≥5.4) have been observed at Tangshan well.We analyze the correlation between
We systematically analyze coseismic responses and post-seismic characteristics of groundwater levels in the Three Gorges well-network to the MS8.0 Wenchuan earthquake on 12 May 2008.The results indica
The diurnal variation of the geomagnetic vertical component is exhibited mainly by changes of phase and amplitude before strong earthquakes.Based on data recorded by the network of geomagnetic observa
Teleseismic body wave traveltime tomography is used to inverse the three-dimensional seismic velocity structure beneath Shizigou in the western Qaidam basin.The travel time are picked from the continu
The two one-state-variable, rate-and state-dependent friction laws, i.e., the slip and slowness laws, are compared on the basis of dynamical behavior of a one-degree-of-freedom spring-slider model thr
The outline and typical characteristics of damages to building in Jiangyou city and Anxian county(intensity VⅢ), Mianyang city and Deyang city(intensity VII) are introduced in the paper.The damage rat
