求翻译一段话

在开始的第一个月 ,失重 3%, 这可能与泡沫中少量未参与聚合的成分在水洗过程中溶出有关.在此后4个月中 ,泡沫失重很少 ,直到气温回升后 6～10月份 ,失重速率显著增加.11 月份后泡沫失重速率又趋减缓. 总体上看 ,泡沫生物降解速率是比较缓慢的 ,即全年降解失重仅 15.61%. 这可能与土壤中微生物对氨基甲酸酯键的适应需要较长的时间有关.另外由于样品为大块状,土壤与泡沫的实际接触面很小 ,也是一个重要原因。 千万别用机器翻译，谢谢 |

I revised a little bit. The entire degradation course of PUF from liquefied wood may be divided into two stages. The initial stage was within the very first five months. After this 5-month period, the weight loss due to biodegradation was nearly 4 %. During this stage, microorganisms moved and adhered onto the surface of the samples, followed by further propagation. The second stage was from the 6th to 10th months, while the weight loss rate of PUF increased rapidly, which was mainly due to the oxidative degradation of soft-segment or degradation of wood components. In general, the weight loss rate of PUF was slow, which was indicated by the annual weight loss rate of only 16.54%. This might be attributed to that the effective contact area between the soil and the samples was relatively small since big bulk samples were used. |

| In the first month, the weight loss is 3%, which may has relationship with the composition in the small amount of foam that not involved in polymerization and dissolving out in the washing process. During the next four months, there is a little foam weight loss until the temperature rose to 10 after 6 months, then the weight loss rate increased obviously. The weight loss rate was towards to slow down After November. Generally, the rate of foam biodegradation is relatively slow,, that is annual weight loss is only 15.61%. This may be the soil micro-organisms to adapt to the urethane bond require a longer duration. In addition, for large bulk samples, the actual contact surface between the soil and the bubble is very small, and that is also an important reason. |
