At that time , owing to the limited construction funds and a lack of related regulations on environmental noise and vibration , dorts referred to the gc report of environmental assessment and thus adopted two remedial measures . one was to draw up contracts stipulating the specification of the environmental control systems and train types for noise reduction . the other was the utilization of continuous seamless welded rails to attenuate vibration 由于当时客观上国内尚未有噪音及振动相关法规，本局又受限于捷运工程经费限制，于参考总顾问报告后，在噪音控制方面：针对环控系统及电联车订定相关合约规范；在减少振动方面：轨道系统采用无缝长焊钢轨。
Selects theimport material production , the quality of material especially supply , feel is good , thickness foot , also its performance all cannot changeunder each kind of temperature , in turn sufficient air pump afterspecial craft processing , no matter from the noise control to aspectand so on durability achieves the international first - class level 选用进口材料生产、质地特柔、手感好、厚度足，且在各种温度下其性能都不会变化，交替充气泵经特殊工艺处理，不论从噪音控制到耐用性等方面均达到国际一流水平。
