Question

翻译一小段话！

实验中要使系统维持过高的真空度非常困难，对抽真空设备的工作性能和散热器的密封性要求很高，这时候散热器内部真空度所能达到的实际数值可能大大低于抽真空设备所要实际抽取的数值。以真空度为4×10-3Pa时为例，此情形下散热器散热效果较真空度为3×10-2Pa提高不明显的原因可能与此有关。

专业词汇：
真空度－vacuum degree
散热器－用HFPR代替
抽真空设备－mechanical vacuum pump
散热效果－cooling capacity
在“挣晕”和“yf177”的帮助下，我将二者的翻译结合了一下。谢谢二位！对比二人的回答，我只能采纳一个为最佳，个人认为“yf177”的回答更为地道一些。我把我最后翻的贴出来，你们来帮我修改一下啊！
It is quiet difficult to hold the vacuum degree at a high level in the experimental system, which needs requirements in an excellent operating performance of the vacuum machinery group and a favorable sealing function of HFPR. Actually, the real value of the inner vacuum degree of HFPR is likely to be lower than the actual value extract by the vacuum machinery group. So far as vacuum degree of 4×10-3Pa concerned, the reason why little improvement of HFPR cooling capacity compared with the vacuum degree of 3×10-2Pa that would mainly about in which mentioned above.

Answer 1

自己个人观点哦,不知道对不对
it's quiet difficult to make the system to maintain so high vacuum degree in an experiment,which needs a superior requirment in the operating performance of vacuum extracter equipment and airtightness of HFPR,the actual numerical value the vacuum degree can reach inside the HFPR is largely likely to be lower than it that extracted by the vacuum extracter equipment at this time,take the vacuum degree at 4×10-3Pa for example,compared to the vacuum degree at 3×10-2Pa ,the reason why the cooling capacity of the HFPR at this situation can't be improved apparently is relevance to this !
the above imformation is just my humble opinion

Answer 2

Experimental system in order to maintain high vacuum is very difficult, vacuum equipment and the work of sealing the radiator demanding, this time to vacuum within the radiator to the actual value could be substantially lower than the pumping Vacuum equipment to be taken from the actual value. A vacuum for 4 × 10-3Pa, for example, the circumstances radiator cooling effect of a vacuum for 3 × 10-2Pa increase, indicating the reason may be relevant here.【软件翻译】

Vacuum - vacuum degree
Radiator - instead of using HFPR
Vacuum equipment - mechanical vacuum pump
Cooling effect - cooling capacity

Answer 4

It's so tough to hold the vacuum degree at a high level of the system in experiment.However high demands needed for the sealing of HFRR and the performance of the machanical vacuum pump.Meanwhile the real value of the inner vacuum degree of HFRR may much less than the actual value extract by the vacuum equipment.So far as vacuum degree 4×10-3Pa concerned,the reason why little improved when compare with the cooling capacity of HFRR on the condition vacuum degree 3×10-2Pa that would mainly about in which mentioned above.

Answer 5

It is difficult to keep high vacuum degree and to the function of machanical vscuum pump and HFPR. At the same time the real figure of vscuum degree inside HFPR may be lower the figure of necessary machanical vacuum pump.eg vacuum degree is 4×10-3Pa.it is possibily related to the reason for vague increase of cooling capacity under 3×10-2Pa vacuum degree .
