The rising temperature in the cave, the lamp - light ' s toasting and the convictive air made the humidity of the whole or part of the cave descend, which made the speleothem sightseeing dry, cracked and weathering. the acid air from the outer and the highly dense co2 would cause acid erode action to the speleothem sightseeing with water vapor. the existence of lamp - light offered a good chance for the lightloving plant to grow up, thus a lot of bryophyte covered the speleothem sightseeing
洞穴升溫、燈光的烘烤及空氣的對流致使洞穴濕度或局部濕度降低，使景觀產生乾裂、風化；氣流帶入的洞外酸性氣體及高濃度co _ 2在高濕的條件下，結合水汽對洞穴景觀產生酸侵蝕作用；燈光的存在為燈光植物生長提供了條件，使大量的苔蘚類植物生長于鐘乳類景觀的表面；洞外大氣粉塵的進入，給洞穴帶來了非常嚴重的破壞，粉塵在洞內高濕的環境下大量沉降，附著于鐘乳類景觀的表面，致使受污染面發黑，毫無光澤。Until now, there have been a few reports on the damage of the water pumps caused by sand and water cavitation. by use of the test loop for solid and liquid two phases, under the condition of 3 % head drop, the damage location and relative degree of the sand and water cavitaiton occurred on the impeller were tested and researched. the result was, them, compared with the results under the condition that water cavitation occurred and no cavitation but only wear occurred. the differencts were analyzed. the analysis result can be used as the basis of the further research and the improvement of the impeller shape
目前含沙水汽蝕對水泵損傷方面的報導甚少，本文利用固液兩相流試驗臺，對離心泵閉式葉輪在含沙水汽蝕時（ 3揚程下降點）的損傷部位和相對程度進行了試驗研究，並將此結果與清水介質發生汽蝕時的損傷情況[ 13 ]及含沙水無汽蝕情況下的磨損情況[ 7 ]相比較，對其差異進行了分析，為今後進一步探討葉輪損傷機理和葉型改進提供了實驗依據。
