The same set of ductile-rheologic shear deformational augen granite samples in the Yunkai uplifted area are measured by whole-rock Sm-Nd, Rb-Sr isotopic dating system method, obtaining respectively 1414±68Ma for Sm-Nd isochron age and 490±36Ma for Rb-Sr isochron age. These ages are respectively interpreted as the time of the granitic rock formation and the time of the tectono-thermal event of ductile-rheologic shear partial melting in Caledonian, indicating that the orogeny not only took place in Caledonian, but also the more important tectono-magmatic orogeny in the late Mesoproterozic Era and can be compared with the time of global Grenville orogeny.
对云开核部韧性-流变剪切变形眼球状花岗岩石样品进行了全岩Sm-Nd、Rb-Sr同位素年龄测定,获得1414±68Ma的Sm-Nd等时线和490±36Ma的Rb-Sr等时线年龄,它们分别代表这套花岗岩的形成时代和加里东期韧性-流变剪切部分熔融构造热事件发生时间,表明云开地区不仅在加里东期发生造山运动,而且在中元古晚期发生了更为重要的构造—岩浆造山运动,其时代与全球性的格林威尔造山运动时间可以对比。

Secondary growth of silicalite-1-seeded industrial CuO-ZnO-Al2O3 in alkaline solution with silica and alumina source produced intergrown ZSM-5 zeolite shells. After the shells were changed into HZSM-5, we compared the catalytical performance of the core/shell composite catalyst with a non-core/shell structured composite catalyst with the same component.
铜锌铝催化剂(CuO-ZnO-Al2O3)是工业上制备二甲醚的良好催化剂,我们将其表面预先包覆纳米沸石silicalite-1晶种,水热环境下二次生长后吸收硅源、铝源后形成ZSM-5膜,转换成氢型后形成CuO-ZnO-Al2O3/HZSM-5的核/壳结构复合催化剂。

objective to study the ct diagnosis of ureteral calculus at the distal end of ureter.methods 82 cases of ureteral caculus were examined by ct scanning.all cases were proved by clinical therapeutic results.results ureteral calculuses were showed as high density image in ct scanning.the ct values of the ureteral calculuses less than 7.5mm in diameter were beyond 83hu.the detection rate by ct was 96.3%.in all the 82 cases,ureteral with calculuses were found dilated and 69 cases with nephrohydrosis.in 13 cases with no nephrohydrosis,caculuses less than 3.8 mm in diameter were found.conclusion ct is the most valuable way to diagnose ureteral calculus at the lower end of ureter.appropriate methods of ct scanning are essential.
