In the section 2, firstly based on the diffusion approximation theory, the temporal characteristics of the reflectance and the transmittance were theoretically analyzed in turbid tissues ; secondly, the curves were simulated that the intensity and the pulse shape of the time resolved reflectance and transmittance versus the absorption a, the scattering s and the anisotropy coefficient g in two different boundary conditions : semi - infinite turbid media and homogeneous slab ; at last, the optical properties can be derived from the curves ; in the section 3, the conditions of ultra short laser pulses of different pulse - width and shapes has been theoretical analyzed and calculated, besides, the simulated the curves of the intensity and pulse shapes of the reflectance and transmittance in a homogeneous slab are obtained for use and future studying
第二章中首先根據漫射近似理論對超短脈沖在以生物組織為典型的混濁介質中傳輸進行了理論分析，然後對兩種邊界條件下產生的漫反射、漫透射光脈沖強度和形狀隨各光學特性參數的變化情況進行了數值模擬，最後得到了混濁介質的光學特性參數與漫反射、透射脈沖強度與形狀的關系曲線。第三章對不同形狀和脈寬的脈沖光源入射到混濁介質中產生的漫反射、漫透射脈沖的強度和形狀進行了理論分析和數值模擬，並將高斯脈沖與方波脈沖情況進行了對比，得到了各種情況的漫反射、漫透射脈沖強度、形狀與各光學特性參數的關系曲線，這對從分析脈沖形狀中提取介質的光學特性參數的信息有重要的意義。 -

迄今為止，國內外對鋼筋混凝土雙向密肋樓蓋的試驗和理論研究很少，特別是周邊支承的情況更是鮮有討論。本文結合試驗，對周邊支承鋼筋混凝土雙向密肋夾心樓蓋進行了理論分析。 -
In the end, the author used fem to analyze the short - period stiffness after rc cellular slab cracking, and presented recommended formulation in respect of short - period stiffness. moreover, with regard to the features of bi - direction cellular slab, the author brought forward the equivalent cross - section stiffness model to calculate the ultimate load - carrying capacity of variable cross - section slab as well as the related reinforcement suggestions and conformation methods
最後本文利用有限元分析了鋼筋混凝土空腹板在開裂后的短期剛度，並給出計算其短期剛度的建議公式；另外針對雙向空腹板的特點，本文提出了對這種變截面板進行承載力計算的「等效截面剛度法」模型，並給出了相關的配筋建議及構造措施。
