1)  induction noise
进气噪声
1.
Taking a four cylinder gasoline engine as an example,S transform was adopted to analyze engine induction noise signal recorded in acceleration in time-frequency domain.
以某四缸汽油机为研究对象,采用S变换技术对加速过程的进气噪声信号进行时频分析处理,研究进气噪声信号能量在时频域内的分布规律,以及其主要频率成分随转速和时间的变化特性,结果表明,发动机进气噪声是与其转速密切相关的非稳态信号,以基频为主,尤其是在低转速段,噪声信号能量几乎全部集中在由基频构成的线性调频带附近,但随着发动机转速的升高,噪声信号的幅值或能量逐渐增大,而且能量分布越来越广泛,频率成分也越来越丰富。
2.
To compare the sound pressure level and frequency characteristic of acoustic signals sampled in the experiment,the induction noise was found to contribute greatfully to the pass-by noise of vehicle left side,where inlet of engine was mounted.
通过实验方法分析研究了一种中型乘用车通过噪声的特性,比较该车进、排气两侧通过噪声的声级和频谱特性,确定了进气噪声对车辆进气侧通过噪声的重要影响。

进气法

进气法   针灸学名词。指针刺手法。《金针赋》:“进气之诀,腰背肘膝痛,浑身走注疼,刺九分,行九针,卧针五七吸,待气上下。”《针灸大成》称作“运气法”:“凡用针之时,先行纯阴之数,若觉针下气满,便倒其针,令患人吸气五口,使针力至病所。此乃运气之法,可治疼痛之病。”意指先直刺,行紧提慢按六数,得气后,将针斜对病痛处,行气后,让吸气五、七口,以助运气。用于各种痛症。《针灸问对》:“针入天部,行九阳之数,气至,速卧倒针,候其气行,令病人吸气五、七口,其针气上行,此乃进气之法,可治肘臂、腰脚、身疼。”
