In this traditional Chinese New Year season, I was triggered with the thought above in big family banquets, loud firework cracking, and wrinkles on parents'faces. 在这传统的中国春节里,家庭盛宴,鞭炮声声,还有父母脸上的皱纹,使我思绪万千。
Results show that the season highways being opened, temperature dropping level and time and material's conductibility of heat ( causes temperature delaying by depth) influence pavement low-temperature cracking, and determine the cracking position. 结果表明,道路开放交通所处季节、温降幅度和时间以及材料的传热性能(导致温度场的滞后)均影响着路面的低温缩裂,并决定了开裂位置的不同。
