暴露

Even people on Earth are exposed to cosmic radiation, but the amount is negligible.

大型太阳风暴产生时，不在地球大气保护中的太空人就会暴露在致命剂量的辐射下，搭乘商用客机飞行在高纬区的人们也会暴露在较高的辐射中，即使是在地球上的人们也是暴露在宇宙辐射中，只不过这些辐射量已经是微不足道的。

Physiological Responses of Hybrid Striped Bass to Aqueous Copper copper is an abundant trace metal, and although essential at low levels, it is also potentially toxic to aquatic organisms.Mechanisms of toxicity and consequences of exposure vary depending on ionoregulatory status(acclimated to freshwater or salt water).The goal of this research was to examine the responses of hybrid striped bass(Morone chrysopsXMorone saxatilis)exposed to Cu in freshwater and 15g/L salt water.In freshwater,a general dose-and time-dependent pattern of increasing Cu accumulation in gill tissue was evident in fish exposed to aqueous Cu(220 and 447 mg/L)for up to 96 hours.The 96-horu acute median lethal concentration for freshwater-acclimated hybrid striped bass exposed to Cu was 94mg/L(confidence interval=62 to 144mg/L).

生理反应到水的混合条纹鲈鱼铜是一个丰富的微量金属，虽然至关重要，它是在较低的水平也可能对水生生物有毒毒性机制及其后果的曝光取决于ionoregulatory状态，本研究的主要目的是为了检查的反应chrysopsXMorone混合条纹鲈鱼暴露于铜在淡水和15 / L盐水在淡水，一般dose-and时变模式日益增长的铜积累鱼鳃组织显然暴露于含水的铜(220和447毫克/升)长达96小时96-horu致命的平均浓度为freshwater-acclimated急性混合条纹鲈鱼暴露于铜被94mg / L(=置信区间来144mg / L)62 osmolatity、钠浓度降低。

Excessive grinding or abrasion of this product may create airbome dust and fober concentrations in excess of state and Federal OSHA permissible exposure limits.if employee exposures exceed these PELs,local exhanst ventilation or other mechanical ventilation systems may be required to reduce such exposures to concentrations below the PELs.if mechanical exhaust ventilation is necessary,exhaust air should be appropriately filtered or otherwise controlled to meet local ,state and Federal air pollution and air quality laws and standards

磨削过度磨损或这种产品可能造成机载尘fober浓度超过州政府和联邦政府1921年允许暴露限定。如果雇员暴露超过这些研究生，局部排气通风或其他机械通风系统，可要求减少这种暴露浓度低于该PELs。如果机械排风是必要的，排风应适当过滤或以其他方式控制，以符合当地，州和联邦空气污染和空气质量法规和标准

But when a individual has developed the disease in exposed case we cannot measure the probability of who would have developed the disease even if he had not been exposed .

但是当一个个体在暴露的情况下发病时，我们无法测量到假若该个体不暴露时也可能发病的概率，因而，我们无法测量暴露对个体产生的效应。

But when a individual has developed the disease in exposed case we cannot measure the probability of who would have developed the disease even if he had not been exposed . Thus we cannot measure exposed effect relative to this individual .

In this study, we use a sample of 186 firms in Taiwan that have export ratio for at least 10 percent in the sample period to examine their exchange rate exposures and the effect of usage of currency derivatives on currency exposures. In the determinants of exchange rate exposure, we find that exchange rate exposure is positively related to the foreign sales ratio, firm size and quick ratio.

过去相关外汇暴露的文献，主要在讨论国际企业的外汇暴露的大小与其决定因子，受限於企业使用衍生性金融商品交易资料取得不易，过去的模型中通常仅以虚拟变数的方式，来分析公司使用衍生性金融商品避险的影响，而未进一步分析其使用程度对外汇暴露的影响。

At the experimental concentrations tested (00 u.g I/1), selenite and selenate did not significantly affect the accumulation of either mercury species by the green mussels. In contrast, selenomethionine significantly inhibited the uptake of MeHg and enhanced the uptake of Hgy the mussels, but it did not affect the assimilation from the ingested diatoms. We further examined the influence of tissue body burden of Se in the green mussels following pre-exposure to selenite and selenomethionine on the accumulation of Hg2 and MeHg from the dietary and aqueous phases.

实验结果表明，在实验设定的浓度范围内(00滩。L-l)，同时暴露，s犷和s产均不能显著影响翡翠贻贝刘榕解态和颗粒态H广和MeHg的累积。seMe育游显著抑制翡翠贻贝对溶解态MeHg的吸收，提高对溶解态H犷+的吸收，但不能影响翡翠贻贝对颗粒态Hg的同化效率；通过投喂载反少或女N贻的硅藻，对翡翠贻贝进行预暴露，组织Se的浓度随预暴露时间延长而增加。

The results show that local exposure affects not only thermal sensations of the exposed body and the whole body, but also thermal sensations of the unexposed body parts.

结果表明，局部热暴露在改变暴露部位和全身的热感觉的同时，也显著改变了非暴露部位的热感觉，据此提出了基于影响因子的分析方法和全身热感觉的预测模型。

Using cosmogenic determinations we have obtained the first in-situ morainal exposure ages from the glacial moraine in the Tanggula mountain and Litang.

本研究利用就地成因的宇宙核素暴露年龄测定方法，对唐古拉山和理塘地区的第四纪冰碛物进行了10Be、26Al和21Ne暴露年龄测定，首次获得了青藏高原的第四纪冰川核素暴露年龄。

Results Risk of lung cancer increased steadily with duration of exposure to nitrosoamine, which roached the peak after a latency, about 20 to 30 years after initiation of exposure, and then lowered rapidly.Conclusion The pettern of exposure to nitrosoamine shown in the rubber workers conformed with the features of a late-stage carcininogen for lung cancer.

结果 肺癌危险度随亚硝胺暴露年数增加而稳定升高，从暴露开始后经过一个潜隐期(大约20～30年)，肺癌危险度达到最高峰，然后迅速下降，结论本资料中亚硝胺暴露对肺癌危险度所显示的结果符合晚期阶段致癌原的特性。
