He looked up to discover that he had bent down the hollow nose needle at a twenty-degree angle. 他抬头一看,发现自己让中空的飞机机头向下倾斜了20度。
In circumstances which cannot be ignored or avoided, daily occurrences right under people's nose are likely to be borrowed, from the angle of sociology, for the use of creative work. 天天发生在眼前的故事,在不能漠视也不能回避的情形下,从社会学角度,挪来为创作所用是可能的。
This paper gives the analysis of a digital compensation method. The experimental results indicate that there are strict requirements for quantization accuracies of ship speed, nose angle, elevation angle, radar operating frequency and PRF, in performing this compensation. 本文分析了用数字方法进行舰速补偿,并作了实验,结果表明:这种补偿对舰速、舷角、仰角、雷达工作频率、重复频率代码等的量化精度都提出了严格要求。
