解釋
氣液界面-
The fractal theory was used to study the character of liquid - vapor interface in the paper, hence the application of the fractal theory in thermal subjects could be solved and a way to calculate the fractional dimension number in the process of simulation could be put forward. the fractional dimension number describing the character of the liquid - vapor interface was calculated. the distinct fractional dimension numbers in x, y and z direction reveal that the simulation system is an anisotropic one
並將分形理論運用到汽液界面的研究中，提出了在汽液界面中計算分維數的方法，得到了描述汽液界面特性的數字特徵變量? ?分維數，同時根據所得到的x 、 y和z方向分維數的不同，證明了汽液界面是各向異性的，並對汽液界面進行了定性和定量的分析，得到了汽液界面是典型的分形面的結論。 -
The distributions of the local density, thickness, temperature, tangential and normal stress and surface tension were acquired by the study of liquid - vapor interface. these simulated data agree well with corresponding experimental data and the md simulation results from other authors, consequently it is proved that the model and simulation method in the paper are correct
對汽液界面進行了分子動力學研究，獲得了汽液界面局域的密度、厚度、溫度、切向應力和法向應力以及表面張力的分佈，並把這些數據與相應的實驗數據和其他作者的模擬結果相比較，吻合較好，從而證明了本文所採用的模擬方法和模擬模型是正確的。 -
The results can be summarized into the following aspects : molecular dynamics study of liquid - vapor interface shows that the planar liquid - vapor interface at macroscopic level is in fact a wavy surface fluctuating with time, and the length scale of the fluctuating region of the wavy surface is the thickness of the liquid - vapor interface. with speckle laser visualized experiment, the fluctuation of the interface can be verified qualitatively. moreover, md simulations indicate that in the liquid - vapor equilibrium system, there exists a local non - equilibrium region near the interface
主要研究成果歸納如下：對汽液界面進行了分子動力學研究，揭示出宏觀尺度的平界面在分子尺度上是隨時間起伏漲落的曲分界面，分界面的漲落區域就是汽液界面的厚度，相應的激光散斑實驗也定性地證明了界面漲落區的存在；研究還發現在汽液平衡體系中，界面附近存在局域熱非平衡區域，並指出了其可能的原因及影響。 -
From the vapor phase to the liquid phase, the temperature jumps near the interface. therefore, it is difficult to accurately measure the temperatures near the interface. this may be the main reason of the large difference between the evaporation / condensation coefficients obtained from different experiments
由於界面處存在明顯的溫度跳躍，界面溫度的準確實驗測量難度較大，這很可能是文獻報道的蒸發/凝結系數的實驗研究結果數據分散程度較大的主要原因。 -
The experimental results of the condensation coefficient obtained from the liquid and vapor temperatures near the interface and the results from md simulations are in the same order, but those obtained from the bulk liquid and bulk vapor temperatures are four to five orders lower than the results from md simulations
採用準穩態方法對水的蒸發過程進行了實驗研究。研究表明，使用界面溫度獲得的蒸發系數實驗結果與分子模擬獲得的凝結系數差距不大，但採用主流區溫度獲得的蒸發系數與模擬計算結果相差可達4 ~ 5個量級。
