"Biodegrade"的意思是生物降解，即生物分解。它是指有机物质在生物体（如微生物）的作用下，逐渐分解和消耗的过程。
以下是一篇关于biodegrade的英文范文：
Biodegradable Materials in Environmental Engineering
Environmental engineers are constantly looking for ways to reduce waste and pollution in the world. One way they are doing this is by using biodegradable materials in place of traditional non-biodegradable materials.
Biodegradable materials are those that can be broken down and consumed by microorganisms such as bacteria and fungi. This process is known as biodegradation. When biodegradable materials are exposed to the right conditions, they will break down over time, reducing their environmental impact.
One example of a biodegradable material is plastic. Although plastic can be very useful, it can take hundreds or even thousands of years to degrade naturally. However, there are now many types of biodegradable plastic available that can be broken down by microorganisms in the environment.
Another example is paper, which is naturally biodegradable. However, if paper is made from non-biodegradable paper fibers, it may not fully decompose in a reasonable timeframe. Therefore, environmental engineers are now looking at ways to use biodegradable paper fibers in paper production.
Biodegradable materials have many benefits for the environment. They reduce the amount of waste in landfills and reduce the amount of pollution caused by non-biodegradable materials. They also reduce the amount of energy used in manufacturing and transporting these materials, which is important for reducing carbon emissions and climate change.
Overall, biodegradable materials are a great way for environmental engineers to reduce waste and pollution in the world. By using these materials, we can all contribute to a healthier and more sustainable environment for future generations.
biodegrade的意思是生物可降解。
在英文范文中的用法如下：
举例来说，当提到"某种材料或者化合物能够被生物体分解吸收，转化为无害的物质"的时候，就可以使用这个词。例如：biodegradable plastic（生物可降解塑料）。
“biodegrade”的意思是生物降解，即指物质受到微生物分解的作用而产生物理或化学变化，而分解为低分子化合物的过程。
关于“biodegrade英文范文最新变化”我无法提供范文，因为“biodegrade”是一个词，没有特定的变化形式。它是一个动词，“降解”的意思，通常与别的词一起构成名词短语，如“biodegradable material”或“biodegradable plastic”。
