This paper reports on the electromagnetic effects on the biological tissue surrounding a transcutaneous transformer for an
artificial anal sphincter. The coupling coils and human tissues, including the skin, fat, muscle, liver, and blood, were considered.
Specific absorption rate (SAR) and current density were analyzed by a finite-length solenoid model. First, SAR and current
density as a function of frequency (10–107 Hz) for an emission current of 1.5 A were calculated under different tissue thickness. Then relations between SAR, current
density, and five types of tissues under each frequency were deduced. As a result, both the SAR and current density were below
the basic restrictions of the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The results show that
the analysis of these data is very important for developing the artificial anal sphincter system. 相似文献

为了解滇南少数民族地区初中生身体素质的发展情况,采用指标测试法(测试指标包括50米跑、立定跳远、引体向上(男)、仰卧起坐(女)、800米跑(女)、1000米跑(男)及坐位体前屈)和数理统计法对滇南少数民族地区中学生身体素质进行研究。研究结果发现:(1)除了初一、初二女生,各年级男女生的速度素质都优于合格标准(P<0.01);(2)男生上肢力量均低于或刚刚达到合格标准(P>0.01);女生腰腹力量初一女生低于合格标准,初二和初三优于合格标准(P<0.01);下肢力量,初三男女生均低于或刚达到合格标准(P>0.01),其它年级男女生优于优于合格标准);(3)各年级男女生的耐力素质、柔韧素质都显著优于合格标准(P<0.01)。此外,从城市班和农村班的比较来看,除女生速度素质和腰腹力量方面,农村班学生均优于城市班学生,但差异不显著(P>0.01)。 相似文献

After research on a 2000t/h subcritical forced-circulation balanced v entilation were applied boiler and the structure and operation of its auxiliary system builds up this heat transfer model of a superheater's pipe wall and analy ze the effect of primary factors on the overtemperature of the pipe wall. Fault tree structure was used to uncover the multiplayer logic between the overtempera ture of the superheater's pipe wall and the faults. 相似文献

A novel artificial anal sphincter system has been developed to simulate the normal physiology of the human anorectum. With the goal of engineering a safe and reliable device, the model of human colonic blood flow has been built and the relationship between the colonic blood flow rate and the operating occlusion pressure of the anorectum is achieved. The tissue ischemia is analyzed based on constitutive relations for human anorectum. The results suggest that at the planned operating occlusion pressure of less than 4 kPa the artificial anal sphincter should not risk the vaseularity of the human colon. 相似文献

After research on a 2000t/h subcritical forced-circulation balanced ventilation were applied boiler and the structure and
operation of its auxiliary system builds up this heat transfer model of a superheater’s pipe wall and analyze the effect of
primary factors on the overtemperature of the pipe wall. Fault tree structure was used to uncover the multiplayer logic between
the overtemperature of the superheater’s pipe wall and the faults. 相似文献
