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。

RESULTS: The transmission electron microscope showed that the retinal photorecepter cells, the retinal pigment epithelium and the retina inner and outer barriers were damaged in the tPVR group. In the tPVR treated with GM 6001 group, the membranous discs of the outer segment of the retinal photorecepter cells were still clear. There were plenty of chondriosome, pinocytosis bullules and smooth endoplasmic reticulum in the cytoplasm. The cell junction was regular.

The results showed that,in spiteof many ultrastructural changes of the fruit epidermis cells during the fruit development,itremained almost unchanged that the cytoplasm was filled with numerous endoplasmic reticulathroughout the whole developmental process.Most of these endoplasmic reticula were tube-likeand rough-ER with enlarged cisterna from which were produced many vesicles. Some of thevesicles were shown to merge into vacuole and to traverse through plasmadesmata.

Through comprehensive comparison,during the growth from 1 age-degree bamboo to 2 age-degree bamboo,density, mechanical strength(except maximum tensile strength etc.),fraction of bundle sheath,cell wall ratio,crystallinity,cellulose content and lignin content increase rate are the greatest.3age-degree bamboo has higher strength,strength and gravity ratio andcrystallinity are the biggest,fraction of parenchyma is small and insect-resistant.2 degree bamboo has the greatest mechanical strength,but its strength andgravity ratio is not the highest and its crystallinity is lower than 3 age-degreebamboo due to its greatest fraction of parenchyma,loss tangent value is thebiggest.Its creep character is not good and is easily eaten by moth.

通过综合比较，竹材从1度竹到2度竹生长过程中，密度、力学强度、纤维束比量、胞壁率、结晶度、纤维素含量、木质素含量等指标增加幅度是最大的。3度竹强度较高，强重比、结晶度最高，薄壁组织含量较小，相对抗虫蛀，材质最好，适合材用。4度竹结晶度下降引起强度的下降，但薄壁组织组织比量最小，相对最抗虫蛀。2度竹力学强度最大，但是强重比并不是最大，结晶度比3度竹低，由于薄壁组织组织比量最大，内耗值最大，蠕变性能较差，同时相对易遭虫蛀。
