Comment: the values for chronic RfD and drinking water as reported in section 4.2 should also be included here.
评论意见:这里还应包括第4.2节中报告的慢性参考剂量和饮用水方面的数值。
An RfD (or RfC) is an estimate (with uncertainty spanning perhaps an order of magnitude) of a daily exposure to the human population (including sensitive subgroups) that is likely to be without appreciable risk of deleterious non-cancer effects during a lifetime.
参考剂量(或参考浓度)是人类(包括敏感亚人群)可能终身都没有非致癌性有害影响的、可察觉风险的、每日暴露量估计值(不确定性跨度可能是一个数量级)。
A dielectric drying system as defined in claim 1 wherein said dielectric drying comprises radio frequency drying (RFD).
如权利要求1所述的介电干燥系统,其中所述介电干燥包括射频干燥(RFD)。
Change the designations RFD and RD (as a meaning for rural or rural free delivery) to RR.
将名称 RFD 和 RD(作为农村或农村免费送货的含义)更改为 RR。

It was concluded that the LOEL could be used for risk assessment purposes if an uncertainty factor of 100 was considered when establishing the RfD.
研究得出结论,若按不确定系数为100计算,在设定参考剂量时,可使用最低观测效应水平进行风险评估。
The RfD value for intermediate duration is based on a LOAEL of 0.18 mg/kg/day established in a subchronic study in rats and applying an uncertainty factor of 300 (ATSDR, 2005).
中期毒性的参考剂量以最低可见毒副反应剂量0.18毫克/千克/日为基础,是在一项针对大鼠进行的亚慢性研究中确定的,采用的不确定系数为300(美国毒物与疾病登记署,2005年)。
A chronic Reference Dose (RfD) of 0.002 mg/kg/day was established based on the results of a ten year chronic feeding study in monkeys in which a NOEL was not determined and a LOEL of 0.2 mg/kg/day was established.
在一项对猴子为期10年的长期喂养研究中,确定该物质的最低观测效应水平为0.2毫克/千克/天,但并未确定其无观测效应水平,美国环保局据此将该物质的长期参考剂量定为0.002毫克/千克/天。
This can be fixed by an administrator after discussion at WP:RFD. If there is only a redirect with no history at the other name, the move will still work - the designers of the MediaWiki software saw this as a special case where nothing will be lost if a move is performed.
这种情况可以在"移动请求"页面讨论后由管理员处理。 如果目标已经存在,但它仅包含一个重定向而且没有任何编辑历史,此时移动仍可正常进行。 Wiki的设计人员将此认作一个特例,这种情况下如果执行移动,没有信息会丢失。
The risk is expressed as a percentage of a maximum acceptable dose or reference dose (RfD).
风险按最大可接受剂量或参考剂量的一定百分比表示。
Chronic RfD = 0.002 mg/kg/day (based on the same study endpoints as for the acute RfD).
慢性参考剂量=0.002毫克/千克/天(根据用于计算急性参考剂量的相同研究结果得出
