到创意工坊connect文件夹里找到新东亚mod文件夹，然后去common文件夹下的technologies文件夹里改装备TXT的代码，找到类似下列字段，重点是把判定全改成“_2_or_3_or_4_”，这样达到脆弱工业就能研究了
allow = {#NEA
nea_has_military_industry_2_or_3_or_4 = yes
}
on_research_complete = {#NEA
if = {
limit = { nea_has_military_industry = yes }
custom_effect_tooltip = nea_new_line_tt
custom_effect_tooltip = nea_dashed_line_tt
custom_effect_tooltip = nea_has_military_industry_2_or_3_or_4_air_techs_tt
