That, in turn, bounces the light down in a concentrated beam about a metre (3ft) wide to produce heat and drive generators.
这个塔又反过来把光以3米宽的光束集中反射到地上，这样可以产生热量和发电。
The low-voltage driving circuit is adopted to drive a piezoelectric ceramic phase shifter to shift the phase of the reference beam, so as to make the instrument lighter, smaller and cheaper.
采用低压驱动电路驱动压电陶瓷相移器对参考光束进行相移，从而使仪器质量减轻、体积缩小、成本降低。
Sootblowers shall have steel box beam construction to enclose the drive mechanism, motor, lance and other moving or hot parts for complete personnel protection and safety.
为了能对人员完全起到保护和安全作用，吹灰器应有钢制箱梁结构来密封驱动机构、电机、吹灰枪和其它活动或较热部件。
