Among those; studies, Liu and Bek have obtained many important results for the theory and applications of Banach spaces and their geometry on complex number,(see [3],[41])Here, we have investigated the TP modulus of convexity and TP modulus of smoothness, on the one hand, we have defined a class of new spaces called uniformly TP convex ,on the other hand, we have extended martingale inequalities and the martingale spaces.This article is divided into four parts, in the first part, we define the TP modulus of convexity and TP modulus of smoothness of Banach space, and prove that the space which is characterized by uniform convexity is same as the space which is characterized by TP uniform convexity. Then we give TP q-uniformly convex and TP p-uniformly smoothable characterization of the Banach space. At the same time, we prove the famous renormed theorem.

Methods and results We assume the carotid arterial wall is the elastic material so we can use the Hooke's law to analyze it. The experiment is based on the use of ultrasound B-mode imaging technique and the off-line image analysis. Elastic tube phantom experiments demonstrated the validity of the technique, providing the size of the tube within 3% of the actual values. The system was also tested in the common carotid arteries of 10 healthy males (age 23.6 y). According to the experimental result, it shows that our index is less variant than Peterson's elastic modulus. The results of and are and respectively.

Results of analysis show that Generalized Paris Law can consider the complex crack propagation in the material of the pavement structure. The fatigue life of the pavement increases with increasing thickness of surface layer in a power function. Use of a thicker surface layer may extend the service life of the asphalt pavement. The fatigue life increases with decreasing modulus of surface layer in a power function with a negative exponent. However, since reduced modulus would scarify the structural strength and might cause rutting-related distress, caution should be taken when using low modulus materials for improving fatigue performance of asphalt pavements. The fatigue life increases with increasing modulus of base material in a power function. However, the fatigue life can not infinitely increases with increasing modulus of the base.
计算与分析表明:广义Paris公式可以考虑沥青路面结构内材料复杂的裂缝扩展:沥青面层的疲劳寿命随着面层厚度的增加以幂函数的形式增加,适当增加沥青面层厚度可以提高路面的使用寿命;沥青面层的疲劳寿命随着面层材料模量的降低以负指数的幂函数形式增加;由于材料模量的降低将牺牲路面的整体强度并可能引起路面车辙类损坏,以此提高疲劳寿命的方法应慎重对待;沥青面层的疲劳寿命随着基层材料模量的增加呈幂函数的形式增加,但由疲劳方程可以看出,寿命并不是随基层材料模量的增加而无限的增加,疲劳曲线在经过一个上升段后,逐渐趋于一个常数值,这说明,这时基层模量对寿命已不作关键性贡献;随着底基层厚度的增加,面层的疲劳寿命近似地呈线性函数增加,但效果并不很明显。
