为提高马铃薯片的热风干燥效率及品质,控制其干燥过程中的收缩变形,本文研究了不同热风温度(45、55、65、75℃)和切片厚度(3、5、7、9 mm)对马铃薯片热风干燥特性曲线、有效水分扩散系数及活化能等指标的影响。结果表明,干燥室内热风温度越高、马铃薯切片厚度越小时,干燥速率越快。在研究范围内,马铃薯片的有效水分扩散系数在5.02×10^(-10)~11.53×10^(-10)m^(2)/s范围内,其值随热风温度升高或切片厚度减小而增大。此外,研究发现Weibull分布函数能够很好地描述马铃薯片的降速干燥过程和收缩动力学模型。通过Arrhenius方程计算得到马铃薯片的干燥活化能和收缩活化能分别为27.35和46.44 kJ/mol,马铃薯片干燥比收缩消耗活化能少。本研究为马铃薯片在热风干燥加工中水分迁移和体积收缩变化的预测提供了理论依据和技术支撑。

采用Gleeble-3800热模拟试验机热模拟压缩试验研究了GH2150合金在不同试验参数下的热变形行为和再结晶演变规律。结果表明,在1000~1200℃范围内,应变速率为0.1~5 s^(-1),变形量分别为30%、50%、70%条件下,合金峰值应力随变形温度升高而降低,随应变速率降低而降低。结合真应力-真应变曲线及阿伦尼乌斯公式得到了GH2150合金的热变形本构方程,采用该方程得到的计算结果与实际结果的平均相对误差为4.36%,相关系数R=0.992,具有较好的吻合性。绘制GH2150合金动态再结晶图发现大变形量有利于提高再结晶分数,合金再结晶行为在50%变形量下主要受变形温度影响,在70%变形量下采用低应变速率更有利于再结晶发生。

可靠声路径（Reliable Acoustic Path,RAP）是深海声传播的重要通道之一，其受界面影响较小，传播损失较低，可以传播到较远的距离，而且在临界深度以下，环境噪声较低；其次，可靠声路径有效避开了多途扩展现象，声线以结构稳定的直达声为主。在总结可靠声路径物理机理和声传播优势的基础上，对比分析了几种不同海洋参数条件下RAP声传播特性，然后采用射线模型仿真分析了RAP声信道内的接收声线结构，之后基于仿真的RAP信道进行了单载波通信性能的分析。仿真结果发现：在RAP声信道内，直达声能量高，传播损失低，声线结构稳定且多途扩展小，对环境变化不敏感，在35km左右的中远程距离内具有很高的信噪比；相同仿真条件下，RAP区域的误码率较同距离浅深度的接收低很多，而且RAP区域接收信号信噪比高出其他区域10 dB左右。该研究结果对于实现垂直方向上深海信息的跨域传输具有重要意义。

肾癌的局灶治疗是通过局部干预直接破坏肾癌病灶,同时最大限度保留周围健康肾组织的精准治疗技术,主要适用于Tla期(肿瘤直径≤4cm)的早期肾癌,尤其是手术风险较高的患者。相比于传统的根治性肾切除术和肾部分切除术,局灶治疗具有对患者一般情况要求低、更加微创、并发症少、恢复快等优势。目前临床上使用的局灶治疗技术主要包括冷冻消融、射频消融、微波消融、不可逆性电穿孔、高强度聚焦超声以及立体定向消融体部放疗。本文综述各种局灶治疗技术的原理、患者的选择,以及局灶治疗技术的肿瘤学结局、并发症和肾功能保护情况。
