請幫忙分析一下這句英語的語法現(xiàn)象和結(jié)構(gòu)
It is the intent of this test that customers,consultants,or competitors be able to easily demonstrate that an IOPS result can be consistently maintained over long periods of time as would be expected in system environments with demanding long term I/O Request Throughput requirements.
這里面demonstrate后面的that是引導一個什么從句?
would be expected in system environments with demanding long term I/O Request Throughput requirements.
請問這個狀語從句怎么翻譯呢？里面又有什么語法現(xiàn)象呢？
