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 |

俺自己写了个版本，仅作交流，非为金币，呵呵 The weight loss was 3% after the first month, which might be attributed to dissolving of the small amount of un-polymerized foams during the washing process. During the 4 months thereafter, the weight loss was strongly reduced. However, the rate of weight loss was remarkedly increased between the 6th and 10th months, due to the raise of ambient temperature. After the 11th month, the rate was decreased again. In general, the bio-degradation rate for foams was rather slow, i.e. the observed weight loss after one year was only 15.61%. This might be ralated to the fact that the microbe needs a long time to accommodate the xxx. On the other hand, the large foam samples lead to small contac area with soil so that the bio-degradation might be somewhat suppressed. |

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. |
