| 摘要: |
| 目的 研究长时间水下模拟运载后潜水员作业能力的变化及规律。方法 在水舱内模拟长时间水下运载环境，利用工效学测试工具分别测定包括注意力、记忆力、情绪调控能力、思维能力、视觉反应能力、触觉反应能力及手动作业能力在不同水下运载时间（0.5、1、2、3、4、5 h）后的变化。结果 长时间水下模拟运载后，上述测试的作业能力均出现不同程度的下降。在模拟运载<3 h，作业能力下降并不明显；在模拟运载≥3 h后，作业能力明显下降且呈加速下降的趋势，与模拟运载0.5 h相比差异均有统计学意义（P均<0.01）。结论 长时间水下模拟运载潜水员的作业能力呈进行性下降，其中水下3 h运载为当前运载条件下的极限。 |

| Abstract: |
| Objective To study the changes of divers' job performance after simulating long-time underwater transport. Methods The long-time underwater transport environment was simulated in the water cabin. The changes of attention, memory, and abilities of emotional regulation, thinking, visual response, tactile response and manual operation were measured at different time points (0.5, 1, 2, 3, 4 and 5 h) with ergonomic tools. Results After stimulating long-time underwater transport, the job performance indexes tested above were all decreased to varying degrees. The overall descent was not obvious within the first 3 h, while it was significantly decreased and showed an accelerated downward trend after simulating long-time underwater transport for 3 h and more, showing significant difference when compared with 0.5 h of simulating long-time underwater transport (all P<0.01). Conclusion Job performance is gradually decreased in divers during simulating long-time underwater transport, and 3-h underwater transport is the limit for current conditions. |
