If the data are well fitted to the regression plane, the estimates of regression parameters α and β, will lead to estimates of the trapped argon composition and the radiometric age for sample.

总而言之，当坐落在相同平面上的资料点群，则代表一个完整封闭之同位素系统。

In this paper the suit of granodiorite is prelimnarily proved to be remelt type granite in which the major rock-forming substances are derived from the crust and a few from the mantle by study on petrology, genetic mineralogy, geochemistry, trace elements, rare earth elments and isotopes combining with the re gional geological evolution and geological chronology.

此次工作，通过进一步对该套岩体的岩石学、矿物学、地球化学、微量元素、稀土元素和同位素等方面研究，并考虑了区域地质演化和地质时代等因素，基本上证明其并非幔源分异型花岗岩，也不是典型I或S型花岗岩，而是一种以地壳物质为主、地幔物质为辅的混源重熔型花岗岩。

Results: MR renogram was similar to radionuclide renography.

结果：MR肾图与同位素肾图类似。

MR dynamic serial images can produce an intensity-time curve in a way similar to that of radionuclide renography. It is useful in the assessment of renal function.

肾脏磁共振动态扫描能产生类似与同位素肾图的MR肾图，对判断肾功能有重要的临床意义。

Materials and Methods: MR dynamic serial images were performed in 10 healthy volunteers. Renal time-intensity curve was calculated from dynamic MR image sets. MR renogram of each normal person was correlated with standard normal radionuclide renography.

对10例健康志愿者进行肾脏MR动态扫描，所得正常的肾脏MR时间－密度由线即MR肾图与标凖的正常同位素肾图进行讨照。

Secondly, the shape coexistence phenomenon in neutron-deficient nucleus〓Hg and the pairing property of Hg isotope are studied with the constrained RMF model.

其次，我们采用带约束的相对论平均场模型，对缺中子的〓Hg的多重形状共存现象及汞系列同位素的对关联进行了研究。

The most possible candidates for proton emissions to be discovered in future experiments are predicted. The superdeformed properties of the even-even isotopes of Zn are also investigated with the RMF theory. It is found that with the decrease of pairing parameter, the superdeformed minima always go through a process from appearing to becoming stable.

还对Zn的偶偶核同位素的超形变性质进行了研究，发现随着对关联的减小，在位能面曲线上，超形变极小值一般有一个从无到有的过程，并且随着对关联的减小，超形变逐渐稳定存在。

Test results and analysis of S, O, D isotopes show that metallogenic minerals come from remelting salic crust and ore-forming fluids are mainly from magmatic water mixed with a little ancient meteoric water.

硫、氢、氧同位素的测试结果及分析表明成矿物质主要来自重熔的深部硅铝质地壳，成矿流体以岩桨水为主，并混有古大气水。

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

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
