In the study of non-isothermal crystallization kinetics, we found that the Avrami constants were enhanced with the increase of the amount of the modified MMT at 10 ℃/min and 30 ℃/min. But it decreased with the increase of the amount of the modified MMT while the cooling rate increase to 50 ℃/min. The crystallization rate constat k also increased with the increase MMT and it revealed that the crystallization rate of composites accelerated by the presence of MMT.

由非等温结晶动力学得知，复材之Avrami 常数n值在10℃/min与30℃/min时，会随著改质蒙脱土含量增加而上升，但是当降温速率提升至50℃/min时，则随著改质蒙脱土增加而下降，其结晶速率常数k值随著改质蒙脱土含量增加而上升，代表复材之结晶速度也会受到添加改质蒙脱土的影响而变快。

The difference between the Malthusian pessimists and the cornucopian optimists," says Postel,"comes down to little more than an assumption about grain land productivity over the next several decades—specifically, whether yields will grow at closer to the 1 percent rate of the 1990s or the 2 percent rate of the previous four decades.

波斯特尔说：&在未来数十年內，持马尔萨斯人口论的悲观主义者和众多乐观主义者的争论焦点，不过是估测农田谷物的生产力而已。具体来说，谷物产量增长率是接近二十世纪九十年代的1%速率，还是接近过去四十年的2%速率？&

The concentration of Cosmogenic nuclides is not only constrained by production rates and exposure time, and also closely related to surface erosion. Furthermore, the concentration is affected by geomagnetic intensity, shielding, chemical weathering, and sample geometry as well. These factors affecting Cosmogenic nuclide concentration should be calibrated when surface exposure age is calculated.

地表物质中宇宙成因核素浓度除了受到核素生成速率和地表物质的暴露时间制约外，还与地表侵蚀速率密切相关，此外，地磁场强度、遮蔽、化学风化及样品的几何位置等也会对核素浓度产生一定影响，在求算样品的地表暴露年代时，应对这些因素进行相应的校正。
