| 1. | Ensure the vapor concentration is lower than lel by 10 %
保证溶剂蒸汽浓度降至lel值的10 %以下。 |
| 2. | The vapor concentration in the booth should be inspected according to the regulations
对舱室内溶剂蒸汽的浓度，要按规则检查测试。 |
| 3. | Provide mechanical ventilation to maintain vapor concentrations below permissible exposure levels
提供机械通风，将气体浓度控制在允许的逸出量以下。 |
| 4. | Provide mechanical ventilation to maintain vapor concentrations below permisble exposure levels
放在供气设备环境下以保持蒸汽浓度不超过允许暴光程度。 |
| 5. | Ventilation : positive downdraft exhaust ventilation should be provided to maintain vapor concentration below tlv
通风：为了使气体聚集程度维持在阀极限值之下，应提供通畅的向下棋流排气通风设施。 |
| 6. | The simulation was began based on defining the boundary which was coupled with heat and mass transfer . numerical simulation was performed with different inlet velocity , temperature , water vapor concentration and channel width
对于数值模拟的结果,采用后处理工具tecplot等进行处理,得到了一、二次空气通道内的压力、速度、温度以及水蒸汽浓度的分布图。 |
