Chapter 5 . based on the measured refractive index distribution curve , according as the theoretical model of light transmission in the grin medium , using quadrivalent runger - kutta method to carry out the light tracking , by this means the mainly imaging character index of the micro - lens such as foci , longitudinal and transverse spherical aberrations aberration etc is calculated . i 第五章從測量所得折射率分布曲線出發，根據梯度介質球內光線傳輸的理論模型，用四階runger - kutta方法進行光線追跡，計算了此種梯度球的縱橫向球差等光學特性，給出所制作梯度折射率微球透鏡成像性能的評價。 |

Locally , the incidence of meningococcal infections is low and about half of the meningococcal infections were caused by neisseria meningitidis serogroup b . the quadrivalent meningococcal vaccine does not confer protection against meningococcal infections caused by serogroup b , its duration of protection is short and it is relatively ineffective in children aged under 2 本港每年的腦膜炎雙球菌感染病例中，約一半為b型的雙球菌所引致。由于腦膜炎雙球菌感染在本港并不常見，加上四價疫苗對b型的雙球菌沒有效用有效期間較短及對兩歲以下兒童的效果較低，故此疫苗并不在本港免疫注射計劃采用之列。 |

In chapter 5 , based on the measured refractive index distribution curve , according as the theoretical model of light transmission in the grin medium , using quadrivalent runger - kutta method to carry out the light tracking , we studied retro - reflection of grin polymer micro - sphere and its application and concluded the best conditions to get good results . in chapter 6 we analyzed the two ways to improve the retro - reflection effect of grin polymer micro - sphere using the light tracking and discuss the pleasant results we got 第五章從上一章測量所得折射率分布曲線出發，根據梯度介質球內光線傳輸的理論模型，用光線追跡的方法分析了327 #微球透鏡的反光性能，并對最佳性能條件進行了總結分析，發現效果提高并不明顯，進而在第六章中提出了提高grin聚合物微球回歸反射性能的兩個基本途徑，并用光線追跡方法進行了詳細的分析，最終得到了良好的效果，并對結果進行了一定的分析解釋。 |
