過天頂測天
英文
back sight-
A pure software solution is given in order to gather more tracking data. the reason of the zenith - blind - zone forming is analyzed detailedly. the conclusion is that the extent of the zenith blind zone was restricted by three parameters : maximum azimuth angular velocity of tracking mount, flight level and airspeed of the target
本文依據不改變系統硬體結構的研究思路，提出一個基於目標軌跡預測技術的解決過天頂跟蹤的方案構想，給出具體實施步驟，預計可使系統單站單圈次跟蹤採集到的有效數據總量提高約一倍。By analyzing and predicting the microclimate in greenhouse in typical weathers, the conclusions are that high temperature with low humidity weather and high temperature with high humidity appear one after the other. the measures are proposed as the followings : to the former, it should be taken to decrease the temperature with soppy shade - fan or spray inside or outside ; to the latter, it should be taken to enlarge the ventilation area, to fit spray apparatus at the top of roof outside, to adopt havelock outside instead inside, to coat the roof white, etc
通過對典型天氣下溫室小氣候變化規律分析和預測，其結論是：從7月中旬到8月中下旬，室內相繼出現高溫低溫和高溫高濕天氣，建議分別採取的適宜措施是：濕簾-風機降溫、高壓噴霧降溫、屋頂噴淋降溫和增大屋頂通風窗的通風面積、安裝屋頂噴淋（霧）設備、改溫室內遮陽為外遮陽、塗白溫室屋頂等。In astronomical coordinates ( reference mark is north latitude 43. 9 ), analyzed is the effect of azimuth angular velocity, acceleration and altitude angular velocity, acceleration etc. some formulae were given to compute all correlative quantities. with regard to the course of data processing beforehand, the thesis focuses on outliers eliminating technology because of outlier increasing acutely of high - elevation tracking ( approaches 10 - 20 % )
在觀測坐標系中推導出確定天頂盲區理論范圍公式和滿足過天項跟蹤條件的關系式；在天文坐標系中以長春衛星觀測站（北緯43 . 9 ）作為計算基準，分別討論了方位、俯仰方向的角速度、角加速度等對天頂盲區的影響，在理論分析上為解決過天頂跟蹤問題打下了基礎。But the only zones in which the moon passes the zenith, the point directly over the head of the spectator, are between the twenty-eighth parallels are the equator.
但是，月亮經過天頂點，也就是說它能夠爬上觀測者的頭頂的地方，必須位於地球赤道和南北緯二十八度之間的地帶。But there are still many things need to do. to improve the situation, under the direction of my teacher, i began to observe the zenith luminance of clear sky and overcast sky. and after analyzing the observed data, i drew the zenith luminance in beijing
雖然如此，通過對北京地區晴天和陰天天頂亮度的觀測，仍可以得到北京地區晴天和陰天天頂亮度隨太陽高度角變化的規律，從而得到天頂亮度值，將其代入cffi標準晴天和陰天天空亮度公式后得到北京地區的晴天和陰天天空亮度絕對值。Spherical metal tank is measured by light tangent method, and the uncertainty of measurement results is calculated by analysing the centre distance, horizontal angle and left and right tangent distance to the top etc
環形金屬罐的測量採用光切法，通過分析中心距、水平夾角、左右切點天頂距等參數，計算球形金屬罐容量測量結果的不確定度。A celestial object will reach its highest position when passing through the semi - circle which includes the zenith and the nearest celestial pole, and this phenomenon is called upper culmination
包括天極天頂和天底的大圓圈稱為子午圈。當天體經過觀測者的子午圈時便稱為中天。We designed five walls for simulate both sides of the top floor. proceeded to add unilateral horizontal static loading experiment to 4 pieces of prestressed small - sized concrete hollow block masonry models and 1 piece of normal concrete hollow block masonry model. crack - resistance behaviors were analyzed, and we have proceeded prestressing loss survey for 25 days, and discussed the reasons of prestressing loss
模擬房屋頂層兩端單元設計試驗模型，進行了4片預應力砌塊砌體墻和1片對比普通墻體水平單調靜力加載試驗，並且進行了25天的預應力損失觀測，探討了預應力損失和加載過程中預應力筋應力的變化等問題，分析了預應力砌體的抗裂性能。分享友人
