由于BGO晶体常用作射线探测器，电子束和快中子是常用的射线源，所以本实验的结果具有一定的参考价值。

When TiO〓 content is increased, the surfacial energy formed by crystals may be reduced, the devitrification degree, strengthened and the content of wollastonite in crystal phase raised; if Cr〓O3〓 content is increased, the crystal size is enlarged, and the content of diopside in crystal phase, raised; if the sulphide content is increased; the reduction atmosphere is heightened and the content of wollastonite become bigger.

晶核剂浓度研究表明，晶核剂浓度不同，对基础玻璃析晶强度，晶相含量和晶体尺寸有一定的影响，当TiO〓含量增加时，可以降低晶体形成的表面能，析晶强度增大，晶相中硅灰石含量增多；Cr〓O〓含量增加，晶体尺寸增大，晶相中透辉石含量增加；硫化物增多，还原气氛增大，同时硅灰石含量增多。

A hematite tone chain leads into the lantern beads and marquee shaped simulated black diamond crystals.

阿赤铁矿音链联想到在灯珠，帐篷形模拟黑金刚石晶体。

Like the Gila monster, which attacks with venom, inflicting festering but fatal wounds? Or merciless assassin snakes with switchblade fangs as sharp as hypodermic needles and enough poison to kill ten people. And they are smart-alligators that send coded messages, iguanas that run on water and the green turtle that uses magnetic crystals in its brain to navigate across the ocean. A Diamondback rattlesnake can inject a tracer to track its dying prey and baby snakes fish for trout with their tongues!

有毒的西拉晰蝎不致命但会令人非常痛楚；有弹弓刀般毒牙的蛇的毒液足够杀死10个人；聪明的鳄鱼以口令的读息沟通；能在水上跑的晰蜴和脑部有滋场导航的海龟；能在猎物体内注入追踪器的棱背响尾蛇，还有用舌头捉鱼的幼蛇。

The composite film appeared semitransparent and brown to yellow from optical microscopy. Results show that shorter time sol-heating results in thiner film with less surface roughness, less conglutination to base, and easily to disconnect, while longer time sol-heating results in thicker film with better conglutination to base and worse roughness. RDX distributes in the film everywhere on the whole but discretely on the scale of 2.4 μm according to EDS results. XRD curve of RDX/RF film shows the superposition of RF non-crystal bread curve and RDX crystals diffraction curve. RDX diffraction peaks are broadened and its crystal size is calculated to be lower to 43 nm.

实验所得薄膜半透明，呈棕红色至黄色；实验表明，溶胶恒温加热时间较短时，所得薄膜的单层厚度较小，较平整，但附着力小，干燥后易脱落；恒温加热时间较长时，所得薄膜的单层厚度较大，不易脱落，但表面平整性较差；能谱测试表明，薄膜中的RDX整体上分布较为均匀，但在测试点位间距为2.4μm的微观尺度上呈离散状分布；XRD测试表明，RDX/RF复合物薄膜表现为RF的非晶态馒头峰与RDX衍射峰的叠加，RDX衍射峰明显宽化，其晶粒度可低至43 nm。
