Semiconductor devices can perform a variety of control function in electronic equipment. 這個試驗是成功的。電工學主要關注的是通過輸送能量做功的情況。 第1節(jié) 翻譯練習3 Particular attention should be given to hoses to ensure that chafing does not occur. The primary concern of electrical engineering is the doing of work by the delivery of energy. Gene piracy is not new. All plants and animals need carbon for growth. 要特別注意軟管保證沒有擦傷。 According to the molecular theory the temperature of an object depends on the average speed of its molecules. Effectiveness of temperature control depends upon the amount of lubricant supplied, the ambient temperature, and the external cooling. 根據(jù)分子理論的原理物體的溫度取決于其分子的平均速度。 內(nèi)蹄式鼓形制動器的防水、防塵性能比較好。 對放射性同位素的最新研究結果表明這種設想是完全錯誤的。 第1節(jié) 翻譯練習2 The parison reveals that the error is due to aliasing.
