查询词典 respirators

To test the respirators fitness, we used quantitative fit test system to measure the fitness of the three models of new respirators worn by real person. The testing method is to use a differential mobility analyzer to select the particles of 40nm in diameter. N95 respirators are capable of filtering out almost all 40nm particles, therefore, the 40 nm particles measured within the respirator would be considered due to the leakage caused by poor fitness.

口罩密合度是使用定量密合度测试组合系统以真人分别配戴三款五年口罩A、B与C和同样型号新口罩来测试其密合度，测试方法主要是利用差异电移动度分析仪筛选粒径为40nm的微粒，而N95口罩的特性几乎可以完全过滤40 nm的微粒，所以口罩内量测到40nm粒径的微粒可被认定是泄漏造成。

In the prevalence of SARS, due to being short of Filtering-Facepiece Respirators, someone had suggested to reuse masks which are disinfected. Though the suggestion goes against the concept of disposability, while in the emergency of epidemic situation and limited resource, the suggestion may be accepted as an emergency measure.

92年SARS疫情高原期，由於抛弃式防尘口罩的供应量不足，有人提出将配戴过的口罩灭菌处理再重复使用的建议，虽然有违「抛弃式」防尘口罩的使用理念，但在疫情紧急且资源有限之际，或许此作法可作为紧急应变的手段。

Purchasing reusable respirators also may reduce or eliminate the impact of potential shortages of filtering facepiece respirators and may be more cost effective over the duration of the pandemic.

购买可更换式呼吸器不仅可以降低或消除随弃式呼吸防护口罩因货源不足造成的潜在影响，而且在流感爆发期间使用时还会更经济。

Surgical respirators are a type of respiratory protection designed for certain healthcare work environments that offers the combined protective properties of both a filtering facepiece respirator and a facemask. Surgical N95 respirators are certified by NIOSH as respirators and are also facemasks cleared by FDA as medical devices.

外科手术用呼吸防备保护口罩是呼吸器的一种，专门为某些医疗环境下的使用而预设，综合了随弃式呼吸防备保护口罩和外科口罩的防备保护功效，医用N95级呼吸器由NIOSH认证核准，可作为呼吸器使用，同时由FDA认证核准，作为医疗器械使用

However,unlike most industrial particles there are no exposure limits, such as Permissible Exposure Limit or Threshold Limit Value, established for biological agents such as SARS. Therefore, respirators are not a guarantee that the user will not contract SARS. Respirators may help reduce exposures

然而，和绝大多数工业环境中存在的颗粒状污染物不同的是，SARS病毒并没有暴露限值，因此，佩戴防护口罩虽然能够帮助降低其暴露水平，却无法保证使用者绝对不接触SARS病毒，即不排除存在暴露的可能，不排除受感染、生病甚至死亡的可能。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
