Aim: To explain and discuss the principle and basis for setting atmospheric pressure limits during torpedo launching in submarine compartment. Methods: Observation of the changes of tympanic membrane and the threshold of hearing in human subjects exposed to different compression rates in pressure chamber and in submarine compartment. Results: When the compression rates were in the range of 2 3 ̄3 0 kPa/s and 3 8 ̄4 5 kPa/s the percentages of normal tympanic membrane after test were 63% ̄85% and 58% ̄64% respectively....

Aim: To explain and discuss the principle and basis for setting atmospheric pressure limits during torpedo launching in submarine compartment. Methods: Observation of the changes of tympanic membrane and the threshold of hearing in human subjects exposed to different compression rates in pressure chamber and in submarine compartment. Results: When the compression rates were in the range of 2 3 ̄3 0 kPa/s and 3 8 ̄4 5 kPa/s the percentages of normal tympanic membrane after test were 63% ̄85% and 58% ̄64% respectively. Most of the testees maintained normal hearing but a few exhibited a 10 ̄20 dB temporary threshold shift. None of the testees showed rupture of tympanic membrane. Conclusion: Based on the above results the following atmospheric pressure limits have been put forward: the appropriate compression rate is 3 04 kPa/s and the maximum compression rate is 4 05 kPa/s.

目的:阐述讨论鱼雷发射时潜艇舱室空气压力容许限值制定的原则及依据。方法:在加压舱及潜艇舱室内受试者暴露在不同的增压速率下观察中耳鼓膜及听阈的变化。结果:当增压速率范围在2.3~3.0kPa/s及3.8~4.5kPa/s时,受试者正常鼓膜的百分比分别为63%~85%及58%~64%。多数受试者保持正常听力,仅个别有10~20dB的暂时性阈移,所有受试者均未发生鼓膜破裂。结论:根据试验结果,提出了如下空气压力限值:适宜增压速率3.04kPa/s,最大增压速率4.05kPa/s。

According to the energy theory of the cylindrical wave, the attenuate rule wave in soil was analyzed. Based oa the relationship between wave energy and amplitude, the formulas about its calculation was given. Combining the testing results with the tolerance limit of the ground vibration, the safe space and some steps of damage prevention was discussed. The results show that the vibration propagates in environment as cylindrical wave, its strength decreases with the quare root's reciprocal of distance.

振动压路机引起的环境振动以波动的形式传播和衰减。根据波的吸收理论,分析了土壤媒质中振动波的衰减规律,按波能与振副的关系,推导了振幅随距离衰减的计算公式,结合环境振动测试结果及建筑物地面振动容许限值,给出了振动压路机的安全工作距离及隔振沟障等危害预防措施。结果表明,振动压路机引起的环境振动以柱面波形式传播并随地面距离平方根的倒数的规律衰减。
