The photonic band gap of 1 - d photonic crystals with graded single refractive index layer is investigated using the method of the characteristic matrix 摘要利用特征矩阵方法研究了一类周期厚度变化的维光子晶体的能带特性。
Finally , the numerical technique was used to investigate influence that different parameters on ablation rate . the relationship between oxygen percentage , pressure , depth of charred layer and ablation rate were obtained 最后计算了不同参数对材料烧蚀率的影响，得到了烧蚀率随富氧含量、试验段压强以及炭化层厚度变化的趋势。
In particular , we were investigating how the thickness of the layers determined whether the superlattice behaved as a metal , with low electrical resistance , or as an insulator , with high resistance 我们已经知道这种超晶格的电性非常有趣，那时我们特别想了解的，是材料层的厚度变化如何让超晶格成为金属（低电阻）或绝缘体（高电阻） 。

The measurement system with ccd has an advantage on the geometrical measure such as thickness for achieving high accuracy , on - line dynamic detection , non - contact measurement , and especially adapts to measure the little thickness alternation 将ccd技术应用于厚度等几何量测量可以实现高精度、在线动态检测和非接触测量等要求，尤其对微小厚度变化量的测量具有很强的优势。
( 4 ) through the analysis on the spread of inner structure , thickness change of strata and seismic and geological data in the southern basin of sertengshan - xitieshan , this paper discussed the response of oblique - thrust effect on basin ( 4 )通过对赛什腾? ?锡铁山南侧盆地内部构造展布、盆地内地层厚度变化以及地震地质资料分析，探讨了赛什腾? ?锡铁山斜冲断裂作用在盆地内的响应。
Taking advantage of hear forces current theory ? this paper deduces the formula of bending shear stresses , in which the influences of axial force , bending moment , variable section depth and the variable thickness of top slab , bottom slab and webs are taken into account 本文利用“剪力流理论”推导出了弯曲剪应力的公式，该公式不仅计及了轴力和弯矩对弯曲剪应力的影响，还计及了截面高度、顶板、底板及腹板厚度变化对弯曲剪应力的影响。
After 20 days at 450 or 1 day at 500 , the u3si2 particles cracked and fragmented , there were a lot of cracks in al - matrix and reacted areas , there were also a lot of holes in the meat . the meat lost its continuity and perfection , and departed from clad . above 450 the volume fraction of the al - matrix and the u3si2 decreased and produced u ( al , si ) 3 in the meat , u3si2 particles invaded to clad 在450热循环20天后、 500热循环1天后，燃料板的厚度变化一般0 . 04mm ，燃料板的翘曲现象严重； u _ 3si _ 2颗粒开裂及破碎，基体中产生大量的裂缝，反应层也存在大量的裂纹及孔洞，芯体已失去连续性、完整性，并且与包壳脱开。
Because of the work mentioned above , a new method of renewing ancient thickness is brought forward , the method of the continuing tendency of the uneroded stratum thickness , the method of the variety rate of the reference layer thickness and the method of the ratio of the contiguous layer thickness are used to renew the erosion thickness in ludong area for the first time and the method of fuzzy synthetic evaluation is used to prioritize the favorable places for prospecting for oil and gas 在此基础之上，提出了一种恢复古厚度的新方法，并首次在陆东地区采用未被剥蚀地层厚度趋势延伸法、参考层厚度变化率法和邻层厚度比值法进行剥蚀厚度恢复，以及采用模糊综合评判方法优选出了有利的勘探目标。
