According to the first, intravertebral vacuum phenomenon is the result of vertebral osteonecrosis,8,14,17,18 whereas the second theory supports that intravertebral vacuum phenomenon signifies nonunion and pseudarthrosis of a vertebral fracture.20,21 A third theory, which did not find appeal, suggested that intravertebral gas could be of intradiskal origin, leaking to the vertebra through the fracture, since a high coincidence (86%) of intervertebral disk vacuum was noted in cases of intravertebral vacuum.6

第一种理论认为椎体内真空现象是椎体缺血性坏死的结果[8，14，17，18]，而第二个理论认为椎体内真空现象意为着骨不连和假关节[20，21]，另外目前还未广泛接受的第三个理论认为椎体内气体可能是从椎间盘中从椎体骨折裂隙中流入的，椎体内出现真空现象的同时伴有椎间盘内真空的比例很高（86％）[6]。

In the deep processing of agricultural and food products, there are some key technological problems of system design on the domestic traditional reelable vacuum aluminium coating system, including mass process parameters, bad process duplication, unstable production quality caused by complex operation, and high equipment failure rate. A newly developed reelable vacuum aluminium coating system with 1500 mm-wide thin plastic films was designed with high vacuum technology in order to satisfy the vacuum aluminum coating of more than 1500 mm-wide, such as polyethylene terephthalate, oriented polypropylene, polypropylene cast film, polyvinyl chloride.

Then the intellectual control technology of vacuum circuit breaker is discussed particularly. As a control object, the bi-stable permanent magnetic actuator is separated into basic principle so as to determine the nature of the whole. The direct-coupled models of magnetic fields for analysis and for calculation are presented. The static and dynamic characteristics of the models and dynamic behavior analysis and matching analysis for the vacuum circuit breaker with bi-stable permanent magnetic actuator are also discussed. For a further study, fuzzy neural network control technology based on synchronized-closing operation of vacuum circuit breaker is analyzed and the research conclusion is used for realizing the synchronized-closing of vacuum circuit breaker in the future.
