Corbicula fluminea (Müller 1774) was bred in the laboratory and two shell samples (shell height, A=13 mm, B=9 mm) were selected to determine the carbon isotopic composition of the increment shells (aragonite, CaCO3) and the host water. The results indicate that the carbon isotopic compositions of the two shells increased as the δ^13 C values of the host water increased from -5.24‰ to 1.41‰, showing the influence of δ^13C values on the shell carbon isotopes.δ^13C value ranges from -4.76% to -2.09% and δ^13 C from -8.49% to -2.89%. The δ^13 C values of shells A and B are both more negative than the predicted equilibrium ones, indicating that the shell had used the metabolic CO2 rich in 12C during their growth process.

对双壳类河蚬进行了室内养殖，并选取两个壳体样品（壳高，A=13 mm， B=9 mm），测定其生长部分壳体和生长期间水体碳同位素，研究表明，随着水体碳同位素的升高（δ^13C由－5.24‰升至1.41‰），两壳体碳同位素也随之升高，表明水体对壳体碳同位素的影响；δ^13CA分布范围为－4.76‰~-2.09‰，δ^13CB为－8.49‰~-2.89‰，壳体A和B碳同位素均比预测平衡值偏负，表明壳体在形成过程中利用了新陈代谢产生的富集12C的CO2。

Simulation result of the experiment shows that unloading and recovery process of PTCS is not consistent with the local stress redistribution and concentration.It can be divided into four phases:1.local stress unloads first in the middle of PTCS;2. stress continues to unload near the incident bar.3.Stress continues to unload near the transmission bar,the first and second layer PT buckling rumple disappear;4.the whole PTCS vibrates elastically.

对具体冲击实验的数值模拟结果表明：相变柱壳的卸载恢复过程在柱壳结构中是不均匀的，伴随着壳体局部应力释放和局部应力集中，可以分为以下四个阶段：1、柱壳中部发生弯曲变形的壳体应力首先释放，2、靠近入射杆端的壳体应力继续释放，3、靠近透射杆端的壳体应力释放，第一层与第二层相变屈曲皱褶消失，4、柱壳整体弹性振动。
