将以下一段话的每一个句子换个说法，意思不变，望高手帮帮忙！ Polyanhydrides exhibit surface erosion, which may prevent covalent aggregation by reducing water penetration into the device. Particles prepared from polyanhydrides degrade completely ranging from days to several months. Another benefit of polyanhydrides is that the pH of the degrading polymeric material does not drop as severely as for PLGA, thus providing a more suitable microclimate for encapsulated (and released) protein molecules. However, these materials are hydrophobic and strong hydrophobic interactions between the polymer and the protein may cause protein adsorption onto the polymer surface, denaturation and non-covalent aggregation.

| Polyanhydrides can exhibit surface erosion, which may prevent covalent aggregation by reducing the penetration of water into the device. Particles prepared from polyanhydrides would completely degrade in days or several months.
