However, RFID stands for Radio Frequency Identification, and is also called as Electronic Label. It goes through radio signals to identify specific targets, and reading and writing information, as well as don't need identity system and specific targets to create such as electronic, optics or machinery. Properties of wireless communication, space-penetrating, information tracking and real-time location system/ RTLS will apply for increasing the system capability of safety and protection to Robot.

而「RFID， Radio Frequency Identification 」称之为「无线射频识别」，又称「电子标签」，是一种通信技术，可透过无线电讯号识别特定目标并读写相关资料，而无需识别系统与特定目标即可建立含电子、光学或机械接触，其特性：无线通讯、空间穿透性、资讯历程可追踪与「即时定位系统 RTLS， Real Time Location System」等，必然将成为机器人、机械手臂安全设计与防护的新应用。

It is considered that lifting the ban on mobile and portable CB radio would satisfy most of the demand for mobile to mobile communications.

而放宽了CB手提及流动无线电可被视为满足对流动电台间日趋频繁的通讯需求量的一个方法。

In Wireless World magazine in 1945, he proposed using a set of satellites in geostationary orbit to form a global communications network.

在1945年的《无线电世界》杂志上，他提议将一系列卫星发射到地球同步轨道上，从而形成一个全球通讯网络。

In 1929, Alfred Traeger built a pedal-powered radio as the communications for the Royal Flying Doctor Service.

1929年，Alfred Traeger发明了踏板动力的无线电装置供皇家飞行医疗服务团通讯使用。

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。
