实时减压是一种适于水下历程多变时的减压技术,本文介绍了一种以串联模型为基础的数学模型和算法,并以美、苏空气潜水减压表为依据进一步修正后,用以指导减压。在加压舱内25～45m 深度下进行了26人次的可变深度潜水和反复潜水,水下总时间为2～3h。多普勒超声监测表明,多数方案可做到无气泡的安全减压。仅1人出现过肘关节的不适,迅速自愈。结果表明,在实验室条件下,本方法体现出一定的优越性。 The real-time decompression is a kind of decompression technology which is suitable for changing underwater course. This paper introduces a mathematical model and algorithm based on the tandem model, and based on the United States and the Soviet air submersible decompression table as a further amendment , To guide decompression. 26 variable-depth diving and repeated diving were carried out at a depth of 25-45m in the pressurized cabin, and the total underwater time was 2-3h. Doppler ultrasound monitoring shows that most programs can achieve bubble-free safety decompression. Only 1 person appeared elbows discomfort, rapid self-healing. The results show that under laboratory conditions, this method shows some advantages.
