The results show that the flow length of microfluid in micro channels that have different section shapes but the same length(50 mm) is in inverse proportion to sections RPA (RPA means the ratio of the section s perimeter to its area),and the smaller the RPA , the longer the flow length.

研究结果表明：微流体在截面形态不同，长度均为50 mm微流道中的流动长度与流道截面的比表面积(截面周长与截面面积的比值)呈反比关系，比表面积越小，流动长度越大；当微流道的比表面积较小时，熔体温度与注射压力对流动长度的影响较大；当比表面积较大时，熔体温度与注射压力对流动长度的影响较小，且不论比表面积如何变化，注射压力对流动长度的影响比熔体温度对流动长度的影响显著。

Found that because the narrowness of the channel, compared with large channel, there have a great difference in bubble behavior and relative character, when used Bowering relation to predict theONB point, this paper given a correlation of C1 = 103.736 Res -0.8 Eu-0.123 to modify theBowering relation to consider the influence of flow velocity and pressure on ONB point.

发现由于流道狭窄，汽泡行为及相关特性等与大流道相比有很大不同，使用Bowering关系式预测过冷流动沸腾起始点时，本文提出了一与流道内的流速和压力条件紧密相关的修正系数C_1，得到了关系式C_1=10~(3.736) Re_s~(-0.8) Eu~(-0.123)，弥补了Bowering关系式中没有考虑流速和压力等因素对沸腾起始点影响的不足。

During growth phase the metabolic flux to glycerol synthesis was much large, and the carbon was mostly catabolized in TCA in the glycerol production process. With large flux through TCA cycle ATP could be overproduced by NADH oxidation and most ATP may be in futile cycle, which may be the reason that the yield of glycerol is hard to be improved.

分析发现菌体生长阶段合成丙三醇的代谢流较大，这可能是细胞为了维持高渗透压环境下正常生理功能所需；但是在菌体生长停止后，产丙三醇阶段合成丙三醇的代谢流并没有增加，而是TCA循环中代谢流增加，于是产生的NADH氧化生成更多ATP，大都ATP可能是无效循环消耗掉，这是丙三醇产率没有达到理想产率的根本所在。

The paper presents that high pressure water jet comminuting technology was used for coal slurry pulverization,and then the comminuted slurry will be graded in a hydrocyclone,the fineness particles obtained from the over flow will be floated,and the coarseness particles from the under flow will be comminuted again.
