我爲谢拉山脉的壮丽景色而欢欣、惊叹。我沐浴在光华之中，观赏清晨雪峰上的日出、午时树木、岩石和积雪的辉映，黄昏斜阳的余晖，还有那飞流直下水花四溅的瀑布。在谢拉山中度过了十年之后，我依然觉得莱特岭是我所见过的大山中最美丽的山岭。

Alpha decay commonly occurs in elements with atomic numbers greater than 83, but can occur in some rare-earth elements in the atomic-number range of 60 to 71.

发射α粒子的主要是重于铋(lutetium，原子序数83)和从钕(neodymium，原子序数60)到镏(Iutetium，原子序数71)的稀土元素，α衰变的半衰期，从1微秒(10-6秒)到约1017秒。

There are 8.6%~10.91% foreign matter in the sphenes, in which radioactive elements of strontium, cesium and uranium range from 4.26% to 4.58%. The change of structural cell parameters of sphenes is still very little,Δa=-0.0009 nm~0.0041 nm,Δb=0.0018 nm~0.0004 nm,Δc=0.0002 nm~0.0048 nm,Δβ=-0.10°~0.09° with high crystallinity of 99.27%~96.46%. Though, the age of sphene from the Fenghuang Mountain is about 1000 Ma, and experienced 775 Ma~1758 Ma geological evolvement and alpha decay, its crystallinity only decreased 3%, and its crystal shape and structure are still fine, indicating that sphene is of good ability to solidify radioactive elements. Therefore, sphenes are ideal minerals for solidifying nucleus waste.

通过对北祁连牛心山变质杂岩体中榍石(775Ma)和山西凤凰山花岗岩中榍石(1758Ma)的XRD及EDS等测试与研究，结果表明：两地榍石的杂质元素质量分数高达8.6%~10.91%，放射性核素锶、铯和铀的质量分数达4.26%~4.58%；晶胞参数的变化极小，△a=-0.0009nm~0.0041nm、△b=0.0018nm~0.0004nm、△c=0.0002nm~-0.0048nm、△β=-0.10°~0.09°，结晶度仍高达99.27%~96.46%，榍石经过10×10^8a的地质作用，结晶度仅减少了3%，显示榍石固化放射性系列核素的能力较强，虽经历了约775Ma~1758Ma的复杂地质演化及其所含放射性核素的衰变作用，其晶体结构完好，稳定性极高，是值得期待的理想核废物固化矿物。
