比较性试验 meaning in Chinese

competitive trials

As we know that this new contact structure was first used in current vacuum interrupter in our country , and a series of comparison tests have been performed . the results indicated that the breaking current density using the new cup - type contact structure is much higher than that of original structure
据我们所知,该种新型杯状纵磁场触头结构在真空灭弧室中的应用属国内首次,制成的试品,在合成回路与原结构产品进行了比较性试验。
Apply the new type touch head structure to vacuum interrupter , make the product of trying on . the comparative test in combination circuit was carried on between the new touch head structure product and the original structure product . the result of test indicated that the vacuum interrupter based cup form horizontal magnetic field touch head structure has greater improvement in the performance of turning on current density than the original structure
将该触头结构应用于现行的真空灭弧室中,制成试品,在合成回路与原结构产品进行了比较性试验,试验结果表明,采用该杯状纵磁场触头结构的真空灭弧室其电流开断密度较原结构有较大的提高。
