這句話的主語(yǔ)"An electric coil"，"worn in a cap"以及"attached to the head with a band"都是過(guò)去分詞做后置定語(yǔ)，表達(dá)一個(gè)被動(dòng)的關(guān)系，---“被裝在帽子里”和“通過(guò)帶子被連到了頭部”，"which"引導(dǎo)定語(yǔ)從句修飾"a band"，"which"在定語(yǔ)從句中做主語(yǔ)的位置，謂語(yǔ)"delivers"，賓語(yǔ)"magnetic pulses"，"to the brain"可當(dāng)成狀語(yǔ)，句子主干的謂語(yǔ)"has been shown"，語(yǔ)態(tài)是被動(dòng)態(tài)；不定式"to relieve..."更像是主語(yǔ)的定語(yǔ)后置，注意"to relieve the symptoms"和"to boost mental performance"是并列關(guān)系。

 

 

研究發(fā)現(xiàn)，把一個(gè)通電線圈裝在帽子里戴上，或是通過(guò)一條帶子把線圈與頭部相連，從而把磁脈沖傳導(dǎo)給大腦，可以減輕嚴(yán)重抑郁癥患者的癥狀，還能提升年輕人的智力表現(xiàn)。
