The process of aging is an example of irreversibility in biology, as cells progressively lose their ability to regenerate.
年老过程是生物学中不可逆性的一个例子，因为细胞逐渐失去再生能力。
The Second Law of Thermodynamics states that in any energy transfer or transformation, there is an element of irreversibility leading to an increase in entropy.
热力学第二定律指出，在任何能量转移或转换过程中，都存在不可逆性因素，导致熵的增加。
Once data has been deleted from a hard drive without backup, its recovery is often impossible due to the principle of information irreversibility.
一旦数据从硬盘上删除且没有备份，由于信息不可逆性原理，其恢复通常是不可能的。
In chemical reactions, certain steps like bond breaking can exhibit a high degree of irreversibility, making the overall reaction effectively one-way.
在化学反应中，某些步骤如键的断裂显示出高度的不可逆性，使得整个反应实际上成为单向的。
The phenomenon of hysteresis, where the state of a system depends not only on its current conditions but also its past history, illustrates irreversibility in many physical processes.
铁磁材料中的滞后现象说明了在许多物理过程中存在不可逆性，即系统状态不仅取决于当前条件还取决于其过去的历史。
When a substance undergoes a phase change from liquid to gas, the process is generally irreversible without external intervention, such as cooling or compression.
当物质从液态变为气态时，这一过程通常是不可逆的，除非有外部干预，如冷却或压缩。
Irreversibility in economics refers to situations where, after making a decision, it is impossible to return to the previous state without incurring significant costs or losses.
经济学中的不可逆性指的是做出决策后，无法在不产生重大成本或损失的情况下恢复到先前状态的情况。
The arrow of time, a concept in physics, embodies the idea that natural processes proceed in a forward direction and exhibit irreversibility, distinguishing the past from the future.
时间之箭，物理学中的一个概念，体现了自然过程向前发展并表现出不可逆性的思想，区分了过去和未来。
In medicine, certain types of tissue damage, such as nerve damage, are largely irreversible, highlighting the need for prevention and early intervention.
在医学中，某些类型的组织损伤，如神经损伤，在很大程度上是不可逆的，这强调了预防和早期干预的重要性。
Environmental degradation, such as deforestation and pollution, often leads to irreversible consequences for ecosystems, emphasizing the urgency of sustainable practices.
环境退化，如森林砍伐和污染，往往对生态系统造成不可逆转的后果，强调了可持续实践的紧迫性。
