3 , the imaging logging data combining with the core data are used to the intervals that has not core data to select the suitable model sample and checkout with the som neural network 3 、用成象测井资料代替未取心井段,结合有的岩心资料挑选出合适的建模样本,并用自组织神经网络对样本的合理性进行验证。
Based on the analyses of coring data and the full waves sonic log data in buohai bay areas , the author summed up all the petrophysical parameters and settle foundation for the realization of fluid substitution 以渤海湾地区岩心分析数据和全波测井数据为基础对岩石物理参数进行了全面总结,为流体替代过程的实现奠定了基础。
In order to further improve the calculation accuracy of oil saturation , the correlation relation is established by way of pressure coring data and then makes pyrolysis analysis data reach the evaluating standard of pressure coring 为进一步提高含油饱和度的精度,通过密闭取心资料建立含油饱和度的校正关系,使热解分析资料评价达到密闭取心评价水平。
Versa also provides facilities - such as full boolean logic and set operations , transitive operations , aggregates , substring matching , and other core data type manipulation - that are lacking in many other rdf query systems Rdf模型是图形结构,该结构可以非常简单也可以令人难以置信的复杂。事实上,极端情况下, semantic web的设想是要创建至少同当前web一样大的rdf模型。
With the information virtualization of core datum such as commercial data and documents , the security problem comes up to the people . the investment in network security constrution has become a new wave for every companies . security investment does not satisfy the demand 随着企业的商业数据、档案文件等核心价值资料越来越多地实现信息虚拟化,安全问题开始浮出水面,对网络安全建设的投资,成为当前各企业新一轮信息化建设的高潮。
On computer systems running Mac OS X and mobile devices running iOS, Core Data is an object graph and persistence framework provided by Apple. It was introduced in Mac OS X 10.
