For removing the effects of interference on the accuracy of test results, many tests must be carried out in a shieldedroom for a long time past.
为了减少无线电干扰对测试准确度的影响，长期以来测试需在屏蔽室中进行。

We have constructed a reliable and economical single-channel magnetocardiogram (MCG) system based on high-T_ c SQUIDs operated in a simply magnetically shieldedroom (MSR).
