Those closest to the radiation are at greatest risk of exposure and the greater the distance away, the lower the risk. 那些最接近的辐射的人群,暴露风险是最大的,离辐射越远,危险越小。
Exposure in turn is dependent on the amount of radiation released from the reactor, weather conditions such as wind and rain at the time of the explosion, the distance someone is from the plant, and the amount of time someone is in irradiated areas. 反之,暴露程度取决于从反应堆释放出来的辐射量,爆炸发生时的天气情况,如风力和降雨,以及当时人们的位置与核电站的距离,人们在核辐射区域呆的时间。
The power ( and hence the radiofrequency exposure to a user) falls off rapidly with increasing distance from the handset. 随着手机传输距离不断加长,功率(以及用户射频辐射接触量)迅速衰减。
Objective To resolve the large area skin defects with bone exposure in the leg with long distance thrombosis of the anterior tibial vessels or the posterior tibial vessels due to posttraumatic lesion. 目的解决小腿创伤后胫前或胫后主要血管之一长段受损栓塞,同时小腿中上段大面积软组织缺损、胫骨外露的创面修复问题。
The major photographic conditions are tube voltage, which relates to the thickness of seed and exposure value, which based on the tube voltage, focal distance and sensitive material. 摄影条件主要取决于管电压和曝光值,管电压与种子厚度有关,曝光值则依管电压、焦片距和感光材料不同而异;
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;
Conclusion Children's lead poisoning is related to environmental pollution, Children's bad habits, their parents 'exposure to lead, and the short distance between their home and heavily-trafficked streets. 结论铅中毒与环境污染、小儿的不良习惯、父母职业铅接触及临街居住有关。
The exposure curve with distance factor 引入距离因子的曝光曲线
The exposure of x-ray is related to discharge types, distance apart from discharge source, electrode materials, discharge voltage, and discharge time and so on. 其照射量与放电型式、放电距离、电极材料、放电电压及放电次数等因数有关。
With the exposure time, the distance between hind legs of ACR group was distinctly on the increase, MT+ ACR group showed a slight increasing trend. 随着染毒时间的延长,ACR组的后肢撑力指数呈明显的增大趋势,MT+ACR组呈轻微的增大趋势。
