His team suggests that at least the smaller buddha might be partially rebuilt with existing fragments injected with a synthetic material designed to halt weathering .
他的团队建议说,利用现有的碎片,通过注入防止风化的合成材料,至少可以部分修复那个较小的佛像。
The rest is removed by slower processes that take up to several hundreds of thousands of years , including chemical weathering and rock formation .
剩余的二氧化碳会被包含化学风化和岩石形成等耗费数百到数千年的缓慢过程所除去。
Sedimentation , weathering , uplift -- all the grand geological forces -- also act as strong chemical agents , breaking and making the bonds of materials .
沉降、风化、隆起所有巨大的地质力量也如强大的化学作用那样,打断或合成物质的分子链。
In many parts of the world , rocks from that era that formed under shallow seas were later exposed to the elements , undergoing the same types of erosion and weathering seen in the australian rocks that retallack analyzed .
