对目前带钢横向温度分布的研究方法和结论进行了分析;对1800热连轧机精轧出口带钢的横向温度进行测量,针对典型的分布规律,提出了描述参数,并用该参数就其分布规律以及分布与带钢宽度、纵向温度的关系进行了讨论,为建立热连轧带钢横向温度控制模型提供了依据

1.1 Physical Fundamentals This attenuation is usually expressed in decibels (dB). By definition, an attenuation of n dB means signal propagation from the that the original field strength is decreased by ite to the user by means of factor of 10-0In electromagnetic waves. Such waves Physical quantities

This is a Geodetic Control Test Field located at L Radial Surveying( Cartwheel): Madison County, Central Ohio. lial Surveys: one receiver at a fixed 2 Madison County High Altitude Test Range site, and measuring lines from this fixed

1.1 Terminology Definitions 3. Point Positioning ys. Relative positioning The coordinates of a single point are determined when 1. Code Range vs, Carrier Phase Code measurements(meter level) Carrier phase measurements(millimeter range). Single point positioning

Perigee and Apogee: The point of closest approach of the satellite with respect to the earth's center of mass is called perigee and the most distant position is the apogee. Nodes: The intersection between the equatorial and the nit sphere is termed the nodes, where the ascending node defines the northward

1. Basic Knowledge of GPS In 1973, DOd organized a Joint P Office (JPO) located at the U.S. Air Force Systems Command's Space The s Second Lecture Division, Los Angeles Air Force Base(AFB)to what?

一、测码伪距绝对定位方法与定位模型 二、测相伪距绝对定位方法与定位模型 三、绝对定位精度评价

一、单基线平差模型 二、模型简单、易于编程实现 三、基线之间相关性被忽略 四、不易发现粗差

假设在同一观测时段,只有两台接收机在一条基线上进行了 同步观测工作。从这一条件出发,根据间接平差原理,讨论载 波相位观测量不同线性组合的平差模型。这些模型易于推广到 多台接收机观测情况
