The unstable stacking of layers of org - mmt was easily damaged under force and heat. hence, it is very important to decide the process temperature for preparing the composites, and it was found that 200 was a upper limitation of temperature
由於在高熱（ 200以上）或強機械剪切作用下，蒙脫土層狀堆疊結構會坍
塌，導致不能與聚合物分子作用生成聚合物?層狀硅酸鹽納米復合材料，因此
熔融插層的溫度選擇顯得十分重要。
Such old zircons could exist in the youngest ash only if they originated in material that was ejected during the oldest eruptions and if that material later collapsed back into the magma chamber and remelted to help fuel the youngest eruptions
這麼老的鋯石能夠存在最年輕的火山灰中，除非它們是來自最古老的噴發物質，而且這些物質后來
塌陷回巖漿庫並再次
熔化，以助於點燃最近一次的噴發。
The slopes of volcanoes such as kilauea become steep and vulnerable to this kind of collapse when the lava from repeated eruptions builds them up more rapidly than they can erode away
要是熔巖不斷噴發而出，且累積的速度比侵蝕還快，像奇勞亞這樣火山的坡度便會越來越陡峭，最後勢必難以招架這樣的坍塌。
