谁给帮忙翻译下边一段,尤其是第一句我翻不出来,翻出来下边的我可以意译了.先给100,翻出来追加100
A thermal buffer tube (or pulse tube) thermally isolates two heat exchangers at different temperatures in a thermoacoustic engine or
refrigerator while allowing the flow of acoustic power.For many heat transport mechanisms,the quality of the thermal isolation depends on the time-averaged mean temperature distribution in the thermal buffer tube,which is determined by boundary conditions set up by the heat exchangers.However,finite-amplitude effects within one peak-to-peak gas displacement of the heat exchangers can lead to significant modification of the thermal boundary conditions and thus the heat transport.To explore these effects,measured mean temperature profiles in the vicinity of the interface between a heat exchanger and thermal buffer tube are reported for a broad range of acoustic and thermal conditions.A one-dimensional Lagrangian model is developed to predict the mean temperature distribution,and reasonable agreement between experimental data and model results is found for the majority of the acoustic conditions considered.

上面的机器翻译简直是乱弹琴.
热缓冲管(或脉冲管)在热声引擎或冰箱中,在不同的温度下对2个热交换机进行隔热,同时允许声功率的流动.对于许多热传输机械来说,隔热质量要视在热缓冲管内的平均时间、平均温度分布情况而定；而平均时间和平均温度分布取决于热交换机所设定的临界条件.然而,热交换机内的气体置换,在正负峰之间的有限振幅的效果可能导致热临界条件的重大更改,这样热就传递了.为了探测这些效果,在热交换机和热缓冲管之间的临界面内,已测定的平均温度曲线图报告给声传感状况和热传感状况的宽带.一维拉格朗日模型开发用来预测平均温度分布,实验数据和模型结果之间的合理协议就给大多数已考虑到的声传感状况找到了.
