It is found thatthe fractal dimension D=1.25 corresponds to the lowest criticalcoupling constant αc=1.9,D=1.73 corresponds to the highest criticalratio of dielectric constants ηc=0.163,and when D≤1.145 bipolaronscan not exist at any rate.In chap,4,we will propose a novelapproach to the calculation of the exciton ground-state energy for thestrong-coupling case.Different from all previous methods,the wavefunction of the phonon part is assumed to take a form related to thewave function of the relative motion.We obtain the exciton energy bysolving the derived integrodifferential equation rather than select ahydrogen-like form to minimize the energy expectation.

结果发现，分数维的维数D＝1.25对应最小的临界的电-声耦合常数(αo＝1.9)，D＝1.73对应最大的临界的介电常数比(ηc＝0.163)，当分数维的维数D≤1.145时，双极化子无论如何也不可能存在，在第四章中，我们将提出一种新颖的变分方法来计算强耦合的激子-声子系统的基态能，不同于以前所有的方法，我们取声子的波函数与相对运动波函数有关的形式，而不是假定一个固定的关于相对运动坐标r的函数形式，得到相对运动波函数所满足的非线性的微分积分方程，我们数值求解这个微分积分方程得到系统基态能，而不是选择一个类氢原子的波函数变分使得能量的期待值最小。

We reviewed the parameters relating to clonal growth, such as internodal length, spacer length and branching angle as well as rhizome elongation and branching rates, of seagrass species. These parameters have determinant impacts on the expanding of seagrass patches. However, breeding system may also affect patch sizes.

His Israelitish origin is attested by the peculiar, rough, Aramaizing diction, pointing to the northern part of Palestine; by the intimate acquaintance he evinces with the localities of Ephraim (5:1; 6:8, 9; 12:12; 14:6, etc.); by passages like 1:2, where the kingdom is styled the land, and 7:5, where the Israelitish king is designated as our king.

Results: Most synovial sarcomas located in the extremities close to joints. Synovial sarcomas detected by radiography typically appeared as round, oval or multilobulated juxtaarticular soft-tissue masses with calcification in some cases. The most common CT appearance of synovial sarcoma was heterogeneous deep -seated soft-tissue mass with attenuation similar to or slightly lower than that of muscle. On T1WI, synovial sarcomas typically appeared as prominently heterogeneous multilobulated soft tissue masses with signal intensity similar to or slightly higher than that of muscle. On T2WI, synovial sarcomas appeared as prominent heterogeneity with predominantly high signal intensity.

结果：大部分滑膜肉瘤位于关节旁；X线表现为圆形、椭圆形或分叶状软组织肿块，部分可见肿块内钙化；典型的CT表现为较深在的、等或稍低密度不均匀的软组织肿块；磁共振T1WI与肌肉信号相比，滑膜肉瘤表现为分叶状、不均匀、等或稍高信号，T2WI则表现为高信号为主的不均匀信号；DSA呈显著的肿瘤实体染色及新生血管。
