The lamp is mainly used in the print and heliograph. 主要用于印刷業(yè),照相版制等。
The heliograph must thus be carefully aligned in the first instance . 回照器在開始時就要小心地對準(zhǔn)。
At last, the further designing content and requirement about the transmission system for solar radio heliograph are proposed. 最后,提出構(gòu)建太陽射電頻譜日像儀光纖傳輸系統(tǒng)需要進一步解決的問題和需深入探討的內(nèi)容。
The feature of optical fiber transmission system and its effect on the solar radio heliograph are analyzed in this article. 摘要分析了光纖傳輸系統(tǒng)的特性,及其對太陽射電頻譜日像儀的影響。
Abstract: Based on actually-surveyed data, an analysis on the precision of infrared distance triangulated heliograph survery was done according to law of propagated error. 文摘:以實測數(shù)據(jù)為依據(jù),按誤差傳播定律對紅外測距三角高程測量的精度進行了分析,提出了在一定距離范圍內(nèi)紅外測距三角高程測量能夠代替三、四等水準(zhǔn)測量。
