The function of collecting meteorological parameters is completed by 1 - wire sensors ( ds1820 , ds2423 , ds2450 ) , adapter ( ds9097u ) and computer . the package can be augmented with humidity , barometric pressure , and other weather sensors simply by connecting the sensor to the cable at the desired position and adding the appropriate software 本系统的气象参数采集部分主要由单总线传感器ds1820 、 ds2423 、 ds2450 、 ds9097u适配器与计算机来完成，可根据不同的需要在单总线上添加其它的传感器和相应的软件测量其它气象参数。
In chapter 2 , the meteorological knowledge , data and the methods of the data processing , related to the study on the atmospheric loads , are simply presented . the model for the perfect gas constant , describes by the relative moisture , is developed . the influences of the variation in the vapor component in the atmosphere on the perfect gas constant are evaluated by using the changing characteristics of the temperature on the surface , its spatial gradient and the barometric pressure 第二章：简要介绍大气负荷研究所需的气象科学知识、资料及其数据处理方法；建立相对湿度表示的大气比气体常数模型，利用地面温度和空间垂直温度梯度、压力变化的规律估算大气水汽组分变化对比气体常数的影响；对中国及邻区的地面气压记录进行了预处理和网格化
The loading effects of the atmosphere are the sum of the direct effect , which comes from its newtonian attraction to any point on the surface or within the interior of the earth , and the indirect effects , which is induced by the earth ' s deformation and additional gravitational potential arising from redistribution of the mass because it can be regarded as the surface loads . they are traditionally expressed as the convolution integration of the atmospheric green ' s function , which is virtually the sum of the elastic and gravitational green ' s functions , and the measured values of the barometric pressure on the earth ' s surface over the globe 随着现代大地测量技术和数据分析手段的日益提高，大气对各类物理场地表观测的负荷影响必须予以考虑，大气的负荷效应为直接效应(大气对地球表面及内部点产生直接吸引)和间接效应(大气作为表面负荷作用于地球，导致地球的弹性形变和内部质量的重新分布，产生附加位)之和，习惯上表示为大气格林函数(弹性项和直接引力项格林函数之和)和地表气压观测值的全球褶积积分
