Food Bioscience 2022年第6期50卷 1204-1216页

The urgent and relevant goals of providing a healthier diet and sustainable food systems taken together require a systematic approach that considers a broader environment for food choice. The paper compares three technologies to produce functional ingredients for preventing oncological diseases - each of them involving different sources of raw materials - a by-product of soybean processing, wild meadowsweet extract and planted meadowsweet extract. Life cycle assessment (LCA) has been selected to justify the choice of raw ingredients and the best technology for the stakeholders. Life cycle inventory analysis (LCiA) of technologies was carried out based on the SimaPro 9.***.1.1. To confirm the results of the LCiA of technologies to produce biologically active substances (BAS) from by-products of soybean oil processing, the following models of the SimaPro 9.***.1.1 software were used: EPD (2018) V1.01, ReCiPe 2016 (Midpoint (H) V1.04 / World (2010) H) and iPCC 2013 (GWP 500a V1.01). The validation of the results and the assessment of the impact of uncertainties in the initial data on the LCA calculations of the technologies were carried out using Monte Carlo method. The results showed that production of BAS from a by-product of soybean oil processing is the most environmentally friendly technology, and the data obtained could add to the life cycle database for the category of “Functional food ingredients” or serve as an example for further research and comparison with other targeted functional ingredients.

本文采用一个新的分析方法研究了冲积浅谷对平面单频Rayleigh波的稳态反应。谷地的形状是圆的,其深度对半宽的比≤1。将传入谷地以及散射的波表为Fourier-Bessel级数,本文的方法就是建立在这个基础之上。在应用应力和位移的连续条件之前,用有限的Fourier级数来近似自由场运动。研究结果表明,谷地一般放大了入射的地面运动,同时,位移的放大和复杂性决定于入射Rayleigh波的频率以及谷地的形状。

研究了冲击波极端条件下玻璃介质的细观结构破坏问题，指出在低于Ｈｕｇｏｎｉｏｔ弹性极限的应力区内，按照细观结构损伤程度的不同，在受压玻璃介质中可以划分出两个区域，即压缩区和破坏区。以Ｋ９和ＺＦ１玻璃为例，通过双层结构样品实验，确认了玻璃样品的表面效应（即表面原生微裂纹的扩展）是破坏区形成的第一位原因。其次，基于对破坏区内细观结构损伤和破坏特性的分析，进一步提出：由于玻璃内部散布的不均匀相与其基体介质之间的压缩率不同，冲击波压缩造成了众多的局域变形点，当表面裂纹扩展到不均匀相与基体的边界处，会出现裂纹扩展路径拐折或分叉，造成介质的分割甚至粉碎，这是破坏区生成的第二位原因。
