仪器飞行

The instruments have shown that albatrosses are capable of astonishing feats of endurance and navigation, and can fly round the world several times without stopping on land .

这一跟踪仪器还表明，信天翁有极强的耐力和航海能力，能够绕地球飞行几圈而不着陆。

In addition, the detailed introduction is given on the endstation of atomic and molecular physics. The formative mechanism of molecular beam is discussed. The theory of time of flight mass spectrometry and multi-photoionization chamber are also discussed in this chapter. Last, the method of data acquisition is described.

另外，对原子分子物理实验站作了具体介绍，讨论了分子束的形成机理、飞行时间质谱仪的设计原理及多级光电离室的原理和结构，给出了该实验站仪器配备情况，并简要介绍了该实验站配套的数据采集方法。

"What this means is that there were refinements over time in the flight apparatus of birds," Baier said.

&这意味着什么，是有改进，随着时间的推移，在飞行仪器的鸟类，&拜尔说。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
