Unable to engage in many activities, my father still tried to participate in some way , when a local sandlot baseball team found itself without a manager , he kept it going , he was a knowledgeable baseball fan and often took me to Ebbets Filed to see the Brooklyn Dodgers play , he liked to go to dances and parties , where he could have a good time just sitting and watching .

虽然不能投身与很多活动中，我父亲仍努力以某种方式参加一些，当地的一个业余棒球队没有经理人时，是他让球队运作起来。他是一个见多识广的棒球迷。常带我去埃贝兹球场观看布鲁克林道奇队的比赛。他喜欢去舞会和派队。在那些场合，他只做着看看就会很开心。

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。

One special communication way of sending and receiving dim signals, making them counter-trans once and a while and laugh and cry in a bizarre manner. Not knowing it was in the hell or the paradise, the man Transo found himself falling into an unfathomable hollow.

The results showed that the population administered with free adjuvant cholera vaccines,both low dose group and common dose group,occurred the weak adverse reaction with 10￣25% rate.The reaction rates between two dose groups of the same vaccine have not significant difference;The reaction rate of the first inoculation(19￣25%) is higher than those of the second inoculation(10￣15%)(P 05);The inoculating local reaction is very light ,only the very few subject occurred the scleroma with 15 mm of diameter.The reaction of aluminum absorbed cholera vaccine is slightly stronger than those of other groups.

结果表明，不加铝佐剂的O139型霍乱菌苗及O1群霍乱菌苗，不论是低剂量组（两剂全程接种45亿菌体）抑或常剂量组（全程接种90亿）接种人群均可产生10～25％的体温呈轻度升高的弱反应，并且同种菌苗的两剂量组的反应率无显著差异；第一剂接种的反应率（19～25％）较第二剂接种的（10～15％）高，P＜0.05；接种局部反应轻微，只有个别受试者出现直径小于15mm的硬结；加佐剂的O1群吸附霍乱菌苗的反应较其它组强。

All our cash was now expended in the variety of particulars we had been obliged to procure, and this countryman's five shillings, being our first-fruits, and coming so seasonably, gave me more pleasure than any crown I have since earned, and the gratitude I felt toward House has made me often more ready than perhaps I otherwise should have been to assist young beginners.
