The result of analysis shows that the convective heat flux has main effect on fuel pyrolyzing and vaporizing , the liquid layer of pe fuel can increase the regression rate but also can cause unstable burning . 4 研究结果表明：对流热流是引起燃料热解气化的主要因素， pe熔化产生的液体层提高了燃料热解退移速率，但液体层厚度增加到一定程度时，对发动机工作稳定性有负面影响。
It is demonstrated that the transmission becomes tunable , depending on the thickness and the refraction index of the slabs deeply : as the thickness of lhm slab in the structure becomes wider , the bragg gap shifts toward higher frequency , in sharp contrast to its shift toward lower frequency as a result of widening the thickness of positive - index - material slab 然后利用传输矩阵法理论分析了这种结构的传输特性,证实了新带隙的存在,同时发现结构的传输特性与结构组成介质的厚度以及折射率密切相关,当正折射物质的厚度增加时,传统bragg带隙会沿频率轴向低频方向移动,若为左手物质则向高频方向移动。
The optical characteristics of metal silver film used as the reflective mirror of microcavity are calculated by characteristic matrix method and it is shown that the thickness of metal mirror affects not only the reflectivity but also the penetration depth and thus the cavity mode . this conclusion is confirmed by experiment 通过特征矩阵法计算了金属薄膜在光学微腔中的性质，得到了金属膜厚度不仅影响腔的品质因子，而且随金属膜厚度增加，由反射相移引起的等效穿透深度增加的结果，并在实验上进行了验证。
Above 450 , the formation of low density u ( al , si ) 3 phase , together with the release of the impurity gas and fragmentation of u3si2 particles , will cause fuel meat to swell , al matrix to crack and u3si2 particles to invade to clad . as a result , the thickness of the meat increased , the thickness of clad decreased and the deformation of fuel plates increased , and the leakage probability of the radioactive mass increased reasonably 同时，由于芯体膨胀及铀硅颗粒碎裂的综合作用，使u _ 3si _ 2颗粒向包壳侵入，最终使燃料板芯体厚度增加较大，芯体及燃料的体积也显著增加，包壳厚度减薄；高温将加速芯体u _ 3si _ 2颗粒碎裂、芯体开裂、包壳以及燃料板变形，从而使燃料芯体与包壳脱开，最终可能导致放射性物质泄漏。
The films prepared under 425 ? is composed with amorphous snoi and its sheet resistance is very high . with the substrate temperature ' s increasing , the degree of crystallization , film thickness increase and electrical resistivity , sheet resistance decrease obviously . when the substrate temperature is higher than 525 ? , the temperature ' s increasing is not of benefit to the films thickness and sheet resistance 常压热分解cvd法制备的sno _ 2在较低基板温度下制备出的薄膜基本上是非晶态的，方块电阻很高；随着基板温度的升高，薄膜厚度增加，薄膜结晶程度提高，薄膜电阻率和方块电阻均显著降低；当基板温度高于525以后，随着基板温度的升高，薄膜厚度基本不再明显增加，薄膜结晶程度继续提高，薄膜电阻率继续降低，方块电阻不再明显降低。
Finally we deduct it from the d - t leakage gamma ray spectra s of iron spheres . from the analysis of gamma - ray spectrum , we find that spectra flux shows certain regularity when thickness of iron shell is increasing . the gamma flux is increasing with the thickness " increasing when thickness is less than 6cm , and it is decreasing when the thickness is more than 6cm 通过分析测量得到的不同厚度的泄漏能谱，发现铁球厚度对能谱通量变化的影响有一定的规律，当铁球厚度接近小于6cm时，泄漏通量随厚度增加呈上升趋势，当厚度接近大于6cm时，通量随厚度增加呈下降趋势。
