Vinegar film is avoided as needed for matrix 14 born prolonged limitations since growth time difference is different from growth substrate material
Brought experimental error.Difficult point of the invention first is that when underwater in-situ acquires flexible glue layer and canal bottom sealing, it is ensured that acquisition
Attached algae is not washed away by water flow.Difficult point is second is that realize that the original position of underwater cylinder is close by the sliding of separation partition after the completion of acquisition
Envelope, it is ensured that sample collected is not revealed in partition sliding process and during device is left the water.Difficult point third is that how
The sliding of separation partition is realized with lesser power under conditions of guaranteeing sealing, so that device has preferable operability.Cause
For being fully sealed to realization device, relatively tight, power needed for sliding separation partition slides is contacted between upper lower clapboard and sealing ring
Measure larger, this is unfavorable for the acquisition of field sample.
