简介:理光将整合组织结构,加强中国业务理光从1972年中日邦交恢复正常开始,马上就展开了中国业务,到现在已经拥有三十年的经营实绩.目前在中国,每年的营业额达到8.4亿美元左右,主要的生产和开发中心有六个.在全国23个城市和35个地点建立了销售和维修网点.集团员工的总数达到7000多名,可以说是行业当中规模最大的.而且,理光计划进一步扩大集团的经营规模.具体来说,针对中国这个将和欧美国家并驾齐驱的大市场,理光会加强本地研发和生产功能.同时,在销售维修方面,把目前分布在23个城市(35个地点)的销售和维修网点重新整合,从而提高决策的速度,为客户提供更高质量的维修和技术支援服务.
简介:从本质上讲,非唯一总是是我们在倒置过程面对的问题,并且它被等价的现象在地,在观察的错误、分离、有限的特征和另外的来源的影响里引起。许多作者在这块地里做了大量研究以便得到更可靠的结果,并且联合倒置是数据的不同类型被联合同时或顺序导出某些信息的繁荣的。这些研究之一是优先的信息例如地质,钻并且地震数据将被用作限制,当倒置过程能被控制时。在这篇文章,我们旨在更好获得三维的密度对比接口使用一个新方法。集成于倒置的这个优先的地震数据能在意味着在地震地点的莫霍接口的深度将被限制的过程起一个抑制作用。它能因此提供可信的结果。以便测试它的效果,这个程序在东北中国在莫霍几何学的领域examplederivation被使用。
