It is necessary for preparing the Y-Ba-Cu-O superconducting ceramic with high quality that the equilibrious liquid phase in the sintering should be prevented by selecting ceramic composition or sintering temperature.

在此基础上，独创了银套Bi-Pb-Sr-Ca-Cu-O超导带的升温处理新工艺，试验了Y-Ba-Cu-O超导陶瓷变氧压处理作低温织构生长的可能性。

The influence of sintering temperature and composition on the microstructure of Y-Ba-Cu-O superconducting ceramic prepared by reactive sintering was investigated. While the oxide powders react and sinter into the superconductor, transient liquid phase can disappear rapidly, and equilibrious liquid phase can promote the anisotropic growth of superconducting grains and isolate the grains.

本文运用X射线衍射、光学金相、扫描电子显微分析、热分析等材料研究手段研究了Y-Ba-Cu-O和Bi-Pb-Sr-Ca-Cu-O两个体系超导陶瓷的超导相与显微组织的形成过程，着重研究了液相在此过程中的作用，同时考察了显微组织与超导性能间的关系。

Again, that would be impossible because SR isn't falsifiable.

我想要再强调一次，这种尝试是徒劳，因为主观真实是不可核实的。

Neither OR nor SR are falsifiable, so you can't prove either of them wrong in an objective sense.

你无法从客观角度证明客观真实或主观真实是错误的，因为两者都不可核实。

Also, there is no formula can be used to calculate errors of these parameters.Based on above reasons, the purposes of the research are to build a reliable geochronological framework of Paleozoic granitoid in study area, to distinguish their genetic types and tectonic settings, and to analyses their orogenic response; to derive a set of formulas for calculating errors of the paramers mentioned above; to ascertain if North Qaidam belongs to North China Block or Yangtze Block.

基于上述存在的问题，本项研究的目的是：建立研究区古生代花岗岩类精确的年代学格架，判别其成因类型和构造环境，分析其造山响应：推演出一套适用于Sr、Nd同位素初始比值和Nd同位素模式年龄等重要示踪参数误差计算的公式；确定柴北缘地区大地构造属性(华北板块还是扬子板块？)。

It was also indicated by the temperature calculation that the lithspheric mantle is stratigraphically layered with the lower part composed by fertile lherzolite and the upper part by refractory harzburgite and clinopyroxene-poor lherzolite.

Sr-Nd-Hf同位素资料反映这些地幔包体均表现为亏损性质，而Re-Os同位素资料确定上述岩石圈地幔形成于中元古代，明显老于上覆地壳的新元古宙时代，反映壳幔年龄上的解耦。

"The evening of May 2 will be Manny's last supper as number one pound-for-pound fighter," continued Mayweather Sr."Ricky's victory will be as sweet as Easter candy and there's no doubt that Ricky will hippity, hoppity all the way home."

&5月2日的比赛，将是曼尼做为P4P砰砰响头牌的最后晚餐，&老梅威瑟接着说，&里奇的胜利将象复活节的蜜糖那样甜，毫无疑问，里奇将欢天喜地地回家。&

Effects of the large non-hydrogenic core ofStrontium atoms were investigated by comparing the experimental Fouriertransformed spectra with hydrogenic closed-orbit theory. The strange peaks inthe experimental spectra were ascribed to combination orbits induced by corescattering of Strontium atoms.

通过对理论计算结果与实验进行比较，研究了非氢原子实对电子动力学行为的影响，发现Sr原子实散射引起的组合轨道在实验回归谱中产生了&奇异&峰。

The comparative studies of lithogeochemistry for the volcano-intrusive complexes both from Jiulongzhang and from xiangshan reveal that the chemical compositions of the volcano intrusive complexes in the two areas are very close, and the trace element spidergrams and REE patterns basically coincide with each other. It is also shown that the two volcano-intrusive complexes have the same source features and the active continental margin tectonic settings. At the same time, it is found that, from early volcanic magma activities to later intrusive magma activities, the content of SiO2 and the Rb/Sr ratio decreased, on the contrary, the content of MgO and the ratios of K/Rb, Ba/Rb and LREE/HREE increased. It is shown that the hypabyssal or ultra-hypabyssal intrusives are not the products of the volcanic magmatic differentiation.

两地区的火山－侵入杂岩的岩石化学成分及其变化特点极为相近，微量元素蛛网图和稀土配分型式也基本一致，它们具有相似的岩浆过程和统一的活动陆缘构造背景；同时，从早期火山岩浆活动到晚期浅成－超浅成岩浆侵入活动，其w(SiO2)和w/w的值降低，而w以及w/w、w/w和w/w的值增高，晚期浅成－超浅成侵入岩与早期火山岩没有直接的分异演化关系。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
