  1. The possible factors including the deviation of temperature in length and breadth of rod, the changes of transfiguration resisting force under the changes of temperature, the adjustment of roll gap, the variation of rolling pressure, the changes of roller speed during dynamic adjusting press, the unmatched of seconds - flux under the dimension fluctuation of the coming sample and so on. the whole system was a closed loop which factors in it interacts each other

    可能的影響因素有:沿軋件縱橫向溫度變化、由溫度引起的軋件變形抗力變化、軋機輥縫值變化、負載變化、電機調節系統由不穩定向穩定過渡過程中軋輥轉速的變化（如咬鋼過程中的動態速降后的回復階段） 、來料尺寸波動造成秒流量不匹配等，整個模擬系統是各個因素相互影響關聯的一個閉環系統。
  2. 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。
  3. The fluctuation characteristics of liquid slug length in the downward inclined pipe with a large range of gas and liquid velocities were investigated on the basis of fractional theory of air / water slug flow

    摘要利用非線性分析技術中的分形理論在較寬的流速范圍內對下傾管中空氣水段塞流的液塞長度波動特性進行了研究。
  4. Then we calculate three correlation lengths in order to see what happens in low density. the second moment density - density correlation length n, 1 is from the density - density structure factor, the second moment charge - charge correlation length z, 1 is from the charge - charge structure factor, and the lebowitz length l is related to the charge fluctuation

    我們計算了與密度一密度結構因子相聯系的密度一密度二級矩關聯長度g川，與電荷一電荷結構因子相聯系的電荷一電荷二級矩關聯長度久； ，以及與電荷漲落相聯系的lebowttz長度乙。
  5. The simulation shows that the valve throttle area should be little as possible but must be more than 40 % of pipe section area ; when the total length of pipe is same, and the flow quantity is enough, pipe before primary valve should be thin and long, and the pipe after primary valve should be thick and short, the upriver and downriver small pressure fluctuation will badly lead to waterdrammer pressure rising, and spending more time in establishing pressure and flow quantity

    模擬表明，閥門過流面積在滿足大於管道截面積40 %的條件下應盡可能小;在管道總長一定並滿足流量要求的條件下，主閥前應採取長而細的管道，閥后則應採用短而粗的管道;上下游微小的壓力波動都會嚴重增大開關閥門引起的水擊，並使壓力、流量的建立需要更長的時間。
  6. Chinese military economy has the characteristic of periodic fluctuation ; the most obvious cycle of chinese military economy is the long fluctuation period of 24 years, and usually the shrinking time is three times the length of the expanding time in a chinese military economy cycle

    摘要我國軍事經濟存在周期性波動的特性；軍事經濟運行周期最顯著的是長周期，其周期長度為24年左右；軍事經濟運行呈現出收縮期長而擴張期短的特點，一般收縮期是擴張期的3倍左右時間。
