Air Negative Ions的意思|示意

Aim: To explore the protective effects of prophylactic inhalation of negative air ions on noise-induced hearing loss and the rule of hearing recovery.

目的：探索预防性吸入空气负离子对噪声性听力损失的保护作用和听力恢复规律。

Meanwhile we contrast the inspect result of the small forest climate and air concentration of negative oxygen ions, in order to be the assistant indexes for the health assessment.

同时对林内小气候和空气负氧离子浓度进行了对比监测，作为健康评价的辅助指标。

The illumination, assessment index of positive and negative ions and total bacteria in office with air-conditioner were lower than those of natural ventilation office (P< 0.01).

空调办公环境的照度、正负离子评价指数及细菌总数均低于自然通风办公环境（ P< 0.01）；

For example, the air is particularly fresh after thunder storm. The reason is because of more negative ions was produced by lightning.

比如在雷雨过后，感到空气格外的清新，这就是因为空气中雷电造成的大量负离子产生的。

Though the negative air ion concentration was sensitive to ambient environment, we found that rape and wheat crops can contribute to increase negative air ions in ambient air.

结果表明：油菜和小麦能增加周边环境中空气负离子浓度，且在幼苗期表现明显；

Sea spray – and, therefore, sea air – is full of negative hydrogen ions, charged particles that neutralise damaging free radicals (positive ions) and improve our ability to absorb oxygen.

大海溅起浪花，因而使海洋空气中富含负氢离子，抵消自由基（阳离子）带电粒子，增强我们的吸氧能力。
