With the helium as the working gas , we attained 119 . 7k the refrigeration temperature of the pulse tube . this is the first time that it enters the cryogenic field using the thermocaoustic engine in china . 2 ) the application of binary noble gas on tadptr after the discuss of the possibility of applying binary noble gas on tadptr , we give the way to calculate the prandtl number of the binary noble gas 混合工質應用于熱聲驅動的脈管制冷機對惰性氣體二元混合工質在熱聲機械中的可能應用進行了探討,給出了混合工質的普朗特數等參數的計算方法,并進行了采用氦-氬混合工質的熱聲驅動脈管制冷機的實驗研究。

In the forth chapter , the sl threshold pressures for bubbles with different noble gases were measured experimentally . results show that the threshold pressure increases with the decrement of molecular mass for gases inside the bubbles 氣泡內的惰性氣體不同使氣泡內的絕熱系數和熱擴散系數不同,惰性氣體的原子質量越大,氣體的絕熱系數就越大而擴散系數就越小。

When the distribution of important fission products is calculated , emphasis is placed on the noble gas radionuclides and upon radioisotope of iodine because of their great contribution to accident dose 在對重要裂變產物分布的仿真計算中,重點放在了惰性氣體核素和碘的放射性同位素上,因為它們是事故中放射性劑量的重要來源。

In 1993 saunders and poreda demonstrated that fullerenes have the unusual ability to capture noble gases ? such as helium , neon and argon ? within their caged structures 1993年,桑德茲與波里達證明了富勒烯具有捕捉惰性氣體(例如氦、氖、氬)的不尋常性質,儲存在球形結構里面。

We knew that the isotopic compositions of noble gases observed in space ( like those measured in meteorites and cosmic dust ) were clearly distinct from those found on the earth 我們知道太空中惰性氣體的同位素組成(像在隕石與彗塵中測量到的情形) ,與地球上的截然不同。

Being a noble gas , it resists chemical bonding with other elements and is thus easy to purify for isotopic analysis 由于氙是惰性的,不易與其他元素產生化學鍵,因此很容易純化以進行同位素分析。

These facts show that the closed configurations of the noble gases are most difficult to disturb by removal of a electron . 這些事實表明,對惰性氣體的閉合電子組態,要移去一個電子以破壞其組態是最困難的。
