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。

In the study of infrared radiation character, different species of tourmaline and Draviteoccurring in pegmatites from Hebei that are different in granularity and heattreatmenttemperature are chose for infrared radiation ratio testing. The result shows:The infraredradiation ratio of tourmaline powder is above 0.80 when the surrounding temperature is 20℃and the testing temperature is below 100℃;Schorl has a close infrared radiation ratio to Dravite,which is higher than Elbaite;No matter to Dravite or Schorl, as the content of ferric oxideincreases, the infrared radiation ratio decreases;tourmaline's size is smaller, its infraredradiation ratio is higher;after tourmaline is heat-treated under 800℃, its infrared radiation ratiodeclines;Dravite heat-treated at 800℃ has the highest infrared radiation ratio, 0.90;andDravite's structure suffers from destruction above 900℃ heattreatment, so its infrared radiationratio goes down.

在红外辐射特性的研究中，本文选择了不同种属电气石、不同粒度和不同热处理温度河北伟晶岩镁电气石进行红外发射率的测试，结果表明：在环境温度为20℃、测试温度为100℃下，电气石粉体红外发射率均在0.80以上；铁、镁电气石红外发射率相近，且大于锂电气石；不论在铁电气石还是在镁电气石中，随氧化铁质量分数的增加，红外辐射率下降；电气石粒径越小，红外发射率越高；电气石在低于800℃以下温度的热处理后，红外发射率下降，800℃热处理电气石红外发射率最高，为0.90，900℃以上电气石结构遭到破坏，红外发射率降低。

Of the five stages deformation, the exact ages of the (2) and (3) were determined by 40Ar/39Ar method as 290 and 259 Ma respectively.2. New results on the metamorphic belts and associated metamorphism of the Xiaopu metamorphic rocksBased on detailed microtextural observations and occurrence of typical metamorphic minerals, five metamorphic belts in the Xiaopu metamorphic rocks are identified. From the north to the south, they are biotite belt, garnet belt, staurolite belt, andalusite belt, and sillimanite belt. I suggested that the metamorphic belts occurred in the Xiaopu area belongs to the high temperature/low pressure series, may have resulted from the later Permian crust extension at ca. 290 Ma.3. I suggest that there may have been a Carboniferous backarc basin along the southern slope of the Harlik Mountain.Detrital Zircon SHRIMP U-Pb dating indicated that the sedimentary age of the Julideneng formation lithic sandstone must be later than late Devonian, most likely is Carboniferous rather than previously thought Precambrian. Analyses on its geologic setting, location of provenance, and sedimentary environment suggest the Carboniferous strata may form in a lagged backarc basin bounded by backarc uplifts.5. Reconstruction of the post-Paleozoic tectonic evolution history of the Harlik MountainThe tectonic evolution of Harlik mountains since the Paleozoic were reconstructed as followings:(1) arc-affinity magmative activities occurred during the middle-Ordovician to early-Silurian;(2) the middle-Silurian to late-Devonian was a back-arc uplift stage;(3) back-arc extension featured the Carboniferous period;(4) post-collisional extension and/then compression during Permian;(5) at the Mesozoic, differential uplift developed; and (6) the late Cenozoic is the intra-continental re-orogen stage.6. Primary estimation of the crust shortening is madeThe folded pre-Mesozoic strata were used to estimate crust shortening along the Harliknanshankou-Koumenzi, Shichengzi-Baishitou, and Qincheng-Xiaopu sections. Their shortening ratios are 16.2%, 19.8%, and 20.1% respectively corresponding crust shortening are 4.3, 9, and 11.3 km.

After this research work, we know that: HMCM-22 is a better catalyst of selecting naphthalene alkylation; Surface modification of zeolite Y is effective, but the effect of zeolite 3 is not evident and surface modification doesn"t suits mordenite; Surface modification doesn"t affect the frameworks and inner environments of zeolites, but only reduces diameter of orifice and overlays surface acidities; t-butanol is not suitable for alkylating agent of the reaction using modified zeolites as catalyst; Solvents with smaller molecular size are advantageous for naphthalene alkylation reaction using modified zeolites as catalyst, such as cyclohexane is better than decalin.

通过本论文的研究，我们知道：HMCM-22是萘择形烷基化反应较好的沸石之一；Y沸石的外表面改性效果较好，β沸石则效果不明显，而丝光沸石则不适于外表面改性；外表面改性不改变沸石的骨架结构和孔道内部环境，仅减小孔口直径和覆盖外表面酸性位；叔丁醇不适于作外表面改性沸石催化的反应的烷基化试剂，其反应活性很低，且选择性无明显提升；分子较小的溶剂更适于外表面改性沸石催化的反应，环己烷就明显好于十氢萘。

The germinative number of horsebeans and peas were raised by 44% with activated water by tourmaline. 200μl 1 X 10~6/ml mouse's H_(22) cell, 200μ 4X 10~6/ml splenic cell, 200μl 1 × 10~6/ml epidermal cell were all inhibited after the action of tourmaline. It is analyzed that the factors which effected the multiplication of the cells included direct action which are tourmaline's electric field, far-infrared, negative ions and solvent ions, and indirect effect which are small water clusters and pH value.

Firstly, the specific surface area of nano-coated particle is much larger than that of ordinary wollastonite, and the edges formed in comminuting is passivated, which made the slippy crystal surface coarsened. At the same time, the color of nano-coated particle became whiter, which fit for light ware. Secondly, if the coated wollastonite hasn't been modified by coupling agent, the toughness of PP/ wollastonite composite couldn't be improved.

在硅灰石表面包覆上纳米级SiO2小颗粒对硅灰石的应用特性有重要影响：①纳米包覆粒子填料的比表面积比普通硅灰石大，纳米级SiO2小颗粒钝化了由于机械力粉碎造成的硅灰石的棱角，使其平滑的晶体解理面变得粗糙，同时硅灰石粉体白度增大，可应用于浅色制品。
