isotropic etching meaning in Chinese

等向性蚀刻
蛤同性腐蚀
各向同性刻蚀
各向同性蚀刻

As the isotropic etching being related to the resistivity of the si material and combining the practical need of the solar cell production , the paper emphasis on the etching of the multicrystal si with resistivity of about 1 . cm . the results : ( 1 ) reflectance characteristics the appropriate etching solutions has led to a reduction of the total integrated reflectance to 5 . 7 % , which is quite comparable with conventionally pretextured si surface covered by a double layer arc
由于以hf + hno _ 3 + h _ 2o为溶液各向同性腐蚀与硅片的掺杂浓度有关，结合生产太阳电池的实际需要，本文重点研究了电阻率1 . cm左右的多晶硅的腐蚀情况，结果如下： ( 1 )反射特性在适当的hf + hno _ 3 + h _ 2o溶液中制备的多晶硅电池的绒面，其反射率降到了5 . 7 。
