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.

Department of Scientific History and Archaeometry; Graduate University of Chinese Academy of Sciences; Beijing 100049;4.Institute of Archaeology; Chinese Academy of Social Sciences; Beijing 100710; China;The fabrication technologies in terms of phase composition,structure,firing temperature,porosity,density and water permeability of ceramic water pipes and contrastive ceramic tilesexcavated from Anyang Yin Ruins of Shang dynasty were studied by X-ray fluorescence,X-ray diffraction and dilatometer,respectively.It was found that the contents of CaO,K2O,MgO and P2O5 in CWP were relatively higher than those in contrastive CT.The difference was further confirmed by the mass ratio of flux...
采用X射线荧光、X射线衍射、热膨胀等分析手段对比研究了安阳商代陶水管的制作工艺,发现陶水管化学成分中各类熔剂的质量分数均略高于对比陶片中熔剂的质量分数,CaO、K2O、MgO等助熔剂与A l2O3的质量比进一步证实该现象,而这种差异性则外在地表现为陶水管的气孔度低于对比陶片以及陶水管热膨胀曲线中出现玻璃化现象,该结果表明陶水管原料应为一种易熔粘土,或者在沉淀粘土中人为地掺和了草木灰类掺和料,这有利于陶水管烧制与成型,有助于熔剂在熔融状态下,较好地进入陶水管中的空隙,使陶水管变得更加致密,一定程度上有利于防止陶水管的渗水,显示出陶水管制作工艺的特殊性。

Tooth Proportions.—There are 17 pitches: 2.5/5, 3/6, 4/8, 5/10, 6/12, 8/16, 10/20, 12/24, 16/32, 20/40, 24/48, 32/64, 40/80, 48/96, 64/128, 80/160, and 128/256. The numerator in this fractional designation is known as the diametral pitch and controls the pitch diameter; the denominator, which is always double the numerator, is known as the stub pitch and controls the tooth depth. For convenience in calculation, only the numerator is used in the formulas given and is designated as P. Diametral pitch, as in gears, means the number of teeth per inch of pitch diameter.

These two things are what we will study in sectionⅢ. We call them GS and PS. In this section we will study the impact of the two and the relationship between them. Of course, there are some other ways to observe the problem. One of them is to consider the period and the distribution of eigenspace. These are what we will study in sectionⅡ.
这两方面也就是本文中第三章所讲的生成序列和扰动序列,这一章中我们主要研究了这两个因素对分数傅立叶变换算子的影响及它们之间的关系;当然还有另一种看问题的角度就是从算子的周期性和特征子空间的分布的角度,这就是第二章中所介绍的内容,在这里我们给出了两个三周期的分数傅立叶变换算子并比较了其特征性质。

Four secondary personalities factors tired all have the remarkable influence to the kindergartener occupation; 6. Kindergartener's emotion dries up differently because of the emotional intelligence total score displays the remarkable difference, the emotion dries up the degree to increase along with the emotional intelligence score drops.

A model describing the relationship between recovery stress and temperature is developed based on the modified Clausius-Clapeyron equation. A composite model based on the Tanaka model is used to calculate the thermal expansion strain of composite, and the relationship between the martensitic fraction and temperature. Results show that this relationship is nonlinear, affected by prestrain and the heating-cooling history.
