Description
Technical field
The present invention relates to a kind of method unsealing objects outside Earth sample sealing packaging containers, belong to technical field of vacuum.
Background technology
According to China's survey of deep space development plan, China samples realizing the unmanned of moon sample before 2017 and returns
Return.Planning according to follow-up developments, China is also visited carrying out a series of deep spaces such as the detection of Mars, Mars sample and return
Survey engineering.In survey of deep space, after gathering the sealing packaging containers return ground of objects outside Earth sample, according to objects outside Earth sample
Handling process, also needs to carry out the deblocking of objects outside Earth sample sealing packaging containers, objects outside Earth sample treatment and preservation etc. a series of
Process.American apollo planning studies shows, objects outside Earth sample is especially sensitive to the water in earth atmospheric environment and oxygen, one
Denier is exposed to earth atmosphere, will occur therewith physically or chemically to react, and make sample lose original characteristic.Therefore, objects outside Earth
Sample gathering, return to ground, unseal, process and during storage etc., how to avoid objects outside Earth sample few by ground as far as possible
On ball, the impact of the factor such as vital movement, water, oxidation, keeps the initial condition of sample as far as possible, is deep space exploration program emphasis
One of problem paid close attention to, is also engineering problem the most urgently to be resolved hurrily.Therefore, objects outside Earth sample sealing packaging containers need to be carried out
Deblocking, objects outside Earth sample treatment and the technique study of preservation and device development, to meet the demand of deep space exploration program.
The research of objects outside Earth sample treatment and preservation is shown by american apollo plan and moon sample museum, extraterrestrial
Process and the preservation of celestial body need to be carried out under high pure nitrogen gaseous environment, it is desirable to every 1,000,000 molecular in high pure nitrogen gas
