为了完善船海工程结构疲劳可靠性评估,弥补Paris公式概率模型在理论和应用上的不足,提出了一种含独立材料参数的Pairs公式的疲劳评估概率模型。基于修正的Paris公式da/dN=C0(△K/K0)^m,应用数理统计理论推导了材料参数C0和m不相关的条件,并根据不相关条件确定K0的值,得到一个材料参数相互独立的Paris公式。通过Ni-Mn-Cr-Mo钢疲劳裂纹扩展速率试验,获得了材料参数的分布特性和特征值,建立疲劳评估概率模型,并验证其正确性。应用该模型对船体板格单元的疲劳可靠性进行分析,给出了不同疲劳寿命下的失效概率。研究表明,这个含独立参数的Paris公式概率模型,避免了疲劳可靠性计算和Monte Carlo仿真中由于参数相关而出现的问题;利用该模型分析船体结构疲劳寿命,计算准确可靠,对于结构耐久性和损伤容限设计、在役安全评价等有重要的参考价值。

Soil biodiversity and crop diversification are vital components of healthy soils and agricultural sustainability

The fast-growing world population exerts great pressure on the land to produce enough nutritious food. It is projectedthat global population will be 50% greater than at present by 2050 and the demand for global grain will havedoubled[1]. The pressure further intensifies with the stresses resulting from climate change, associated extremeweather[2], and expansion of urbanization. Humanity has already transgressed three of the nine interlinked planetaryboundaries, and agriculture is the major driving force behind this development^1. The agricultural system must betransformed to simultaneously provide global food security and environmental integrity[4]. To address thesechallenges, sustainability in agriculture must be enhanced13,51. This is particularly true for rapidly developingcountries such as China. While intensive, industrial agriculture achieved enormous successes, such as feeding 20%of the global population by producing 25% of the world’s grain with less than 10% of world arable land, theseachievements came at the expense of low resource use efficiency and environmental problems such as airpollution161, water pollution171, and soil acidification[8]. Agriculture in China is facing unprecedented challenges.
