在高纬度地区 meaning in Chinese
high latitudes
Examples
- A study published in january in the journal of the american college of cardiology , for example , suggests that the amount of caffeine in two cu of coffee significantly decreases blood flow to the heart , particularly during exercise at high altitude
比如说，刊登在1月份美国心脏病学会志上的一项研究结果认为，两杯咖啡中含有的咖啡因可以显著的减少流向心脏的血液，特别是在高纬度地区锻炼时。 - A study published in january in the journal of the american college of cardiology , for example , suggests that the amount of caffeine in two cups of coffee significantly decreases blood flow to the heart , particularly during exercise at high altitude
比如说，刊登在1月份美国心脏病学会志上的一项研究结果认为，两杯咖啡中含有的咖啡因可以显著的减少流向心脏的血液，特别是在高纬度地区锻炼时。 - Its main contributions include the following several aspects : firstly , the dissertation constructs the mathematic model of short baseline orientation determination using two geostationary satellites and analyses the applicable conditions of carrier phase interferometry . orientation determination precision is analysed in depth through both the conventional linearized method and monte - carlo computer simulation method , and the mathematical simulation results show that the linearized method has the shortcoming of fairly low elevation error analysis precision in high latitude area so as not to be very appropriate there . by analyzing the definite factors influencing orientation precision , the dissertation develops the concept of orientation dilution of precision , which uncovers the internal cause of exotic error behavior of bi - satellite orientation , and has important guiding significance for practical engineering applications
本文系统地研究了基于“北斗一号”卫星载波相位干涉测量原理实现地球静止双星定向的相关技术,主要研究成果包括以下几方面:首先,建立了利用两颗地球静止轨道卫星进行短基线定向的数学模型,分析了载波相位干涉测量的适用条件;采用传统的线性化解析法及蒙特卡洛随机模拟法两种途径对双星定向的精度进行了详细分析,数学仿真结果表明在高纬度地区线性化解析法由于俯仰角误差分析精度略有下降而不太适合;在分析定向精度确定性影响因素的基础上,提出了双星定向精度衰减因子odop的概念,揭示了双星定向误差特殊表现的内部机理,对实际工程应用具有重要的指导意义。
