无定形的

Based on 3D steady and incompressible N-S equation and k-ε turbulent model, the aerodynamic performance of three different design options of 160 km/h container flat wagon was analyzed and compared using finite volume method. The three design options are as follows: the first design option has no headwall and the side surface of side beam is flat; the second and the third both have headwall and high side beam, and the side surface of side beam of the second is obtuse, while the third is cambered.

基于三维、不可压、定常N-S方程和k-ε双方程湍流模型，采用有限体积法对3种不同设计方案在运行时速为160 km/h的集装箱专用平车在有、无横风情况下的气动性能进行分析与比较，其中：方案一的平车无端墙，侧梁侧面平直；方案二和三的平车均加有端墙，且侧梁加高、侧面形状分别为钝形和弧形。

摘 要：基于三维、不可压、定常 N S 方程和 k ε双方程湍流模型，采用有限体积法对3种不同设计方案在运行时速为160 km/h的集装箱专用平车在有、无横风情况下的气动性能进行分析与比较，其中：方案一的平车无端墙，侧梁侧面平直；方案二和三的平车均加有端墙，且侧梁加高、侧面形状分别为钝形和弧形。

The results showed that 22.5μL/L of clove leaf oil had the best preservation effect on peach. After 35 days of stock, the sound fruit rate was 94%, 46.9% higher than compared group. The rotten index and the browning index were 94.1% and 85.2% lower than the control, respectivly, and the treatment could remarkablely reduce the respiration rate and ethylene release, and postponed ethylene release peak and respiration peak 5 and 10d, respectively in comparison with CK, it also delayed the drop of firmness and contents of titrable acids of the peach. When stored for 35d, firmness of control group and 22.5μL/L of clove leaf oil were decreased 60% and 34% compared with initial storage, and the activities of SOD, CAT and POD were enhanced, but the contents of SSC had no obvious difference with control.

结果表明，与对照相比，22.5μL/L丁香叶油处理对桃果实的防腐保鲜效果最好，贮藏35d时好果率为94%，比对照提高了46.9%，腐烂指数和褐变指数分别比对照低94.1%和85.2%；丁香叶油处理可以有效降低桃果实的呼吸强度和乙烯释放量，呼吸强度高峰和乙烯释放量高峰分别推迟5和10d，延缓了果实硬度和可滴定酸含量下降的速度；贮藏35d时对照和22.5μL/L丁香叶油处理果实硬度分别比贮藏初期降低了60%和34%；丁香叶油处理提高了超氧化物歧化酶、过氧化氢酶、过氧化物酶3种膜脂过氧化物酶的活性，但可溶性固形物含量与对照相比无明显差异。
