纽曼是一个大家很熟悉的品牌,它的产品大多是以MP3、MP4等移动数码为代表,借着"纽曼梦想中国"、"纽曼唱响中国"等全国性活动而在大江南北名声大噪。正是这个以"音乐成就梦想"为口号的企业终于也经不住汽车用品市场的诱惑,在朗科、中恒等同行之后,推出了 GPS 导航产品——天下通 E666导航仪。GPS 导航仪是一种对车主十分有用的产品,但是普及却很困难,虽然各方在产品开发上挖空心思,拼尽全力都似乎无
The HIV-1 gp120 exterior envelope glycoprotein undergoes a series of conformational rearrangements while sequentially interacting with the receptor CD4 and coreceptor CCR5 or CXCR4 on the surface of h
BACKGROUND: Hepatocellular carcinoma (HCC) is characterized by multicause, obvious multistage and multifocal processes of tumor progression. The development of HCC is related intimately to overexpress
本文主要阐述GPS-RTK测量技术在布设图根控制点中具体勘测实施情况。
本文根据常用的GPS水准高程拟合模型,利用测区的已知数据进行试算,并根据试验结果,从拟合的似大地水准面,已知点高程精度和GPS点大地高三方面,分析了GPS水准高程拟合精度,总结了提高拟合精度一些方法
虚拟参考站技术作为当今GPS技术发展的方向之一，结合本地的资源搭建具有特色的虚拟参考站系统，并对VRS系统管理与应用的经验进行了总结和对系统有待解决的问题进行了思考。
The expert knowledge has been widely used to improve the remotely sensed classification accuracy. Generally, the ex-pert classification system mainly depends on DEM and some thematic maps. The spatial
With remote sensing information products becoming increasingly varied and arguably improved, scientific applications of such products rely on their quality assessment. In an operational context such a
For centuries, explorers and scientists from different countries had made their own conclusions on the source of the Mekong. However, the geographic source of the Mekong is still arguable because of t
In the field of converting simulation surveying and traditional close range photogrammetry, it has been developed so far to survey objects by commercial digital camera and this technique is applied wi
