The power (and hence the radiofrequency exposure to a user) falls off rapidly with increasing distance from the handset.
与手机的距离增加后，功率(以及用户射频辐射接触量)迅速衰减。
At a distance of several football fields, the sensation from the exposure was like a blast from a very hot oven, too painful to bear without scrambling for cover.
在几个足球场的距离内，被辐射的感觉就像是滚烫的烤箱里吹来的一阵热风，要是不趴下加以躲避的话，根本没法忍受这样的高温。
Are you used to observing the world with distance in your life, like lighting a cigarette during the time of exposure without any personal comment.
生活中的你是不是对世界也保持着疏离的观察，比如叼根烟、不带评价地等曝光时间过去？
The effect of working parameters on the erosion performance of underwater jet is investigated, such as , simulated depth, stand off distance and exposure time.
试验研究了模拟水深、靶距及冲蚀时间对水下射流性能的影响关系，较全面地揭示了水下射流的特性。
Then, exposure conditions including the exposure dose and source to film distance were changed to find the optimal one.
改变源片距离和曝光剂量，进一步突出所能发现的误差，确定最佳曝光条件；
Purpose To establish a screen film system sensitometric method of X ray scale exposure by changing the distance between focus and film.
目的建立以焦点胶片距离的改变，取得X线阶段曝光的屏片体系感光测定方法。
The setup can therefore be used with larger sources placed at shorter distance of the detector resulting in higher flux densities and thus shorter exposure times.
因此，该装置可以和被置于检测器的较短距离处的较大源一起使用，从而导 致较高的通量密度和因此较短的曝露时间。
There are three factors that minimize radiation exposure to your body: Time, Distance, and Shielding.
要最大程度减轻辐射伤害，三个因素至关重要：时间，距离和庇护所。
