To address the issue, we analyze the correlation and similarity of the different radii sequence and the different combination sequence with the full- ring-sample sequences, based on 642 δ13C data of cellulose fixed in tree-ring at 8 different radii of two Cryptomeria fortunei tree disks from Mt. Tianmu, a subtropical mountain of China. It suggests that 2 to 4 radii mixture sample is the better and more efficient choice for the tree-ring δ13C analysis. It had better to take samples at obtuse angle with each other when to take samples at two or three radii.

研究利用来自天目山的两个柳杉树盘的多方位的和整轮的碳同位素测试数据（共计642个），通过不同方位和不同方位组合的平均碳同位素序列与整轮碳同位素序列的关系的多角度的考查、分析发现，并不是采样的方位数越多越好，选择2~4个方位采样合并分析树轮稳定碳同位素，既经济方便又能比较好的反映一棵树的δ13C变化过程与趋势。

Transmission X-ray diffraction analysis showed that high crystal orientation occured in the shear layer for both samples,and the SIF sample exhibited a lower orientation degree of the crystal (040) planes as compared with the CFP sample.

透射X-射线衍射的检测结果表明SIF样和CFP样在剪切层晶体具有大的取向效应，SIF样晶体的取向度为65%，而CFP样则为79%。

Based on the genome conservative sequence of tabacoo mosaic virus, cucumber mosaic virus and potato X virus, special primers were designed respectively. With the RT-PCR, the target fragments about 313,326 and 392 bp were ampilfied separately from the infected sample, but not health sample.

设计烟草花叶病毒、黄瓜花叶病毒和马铃薯X病毒的特异性引物，RT-PCR检测，从感病叶片中分别扩增出313，326，392 bp的目的片断，而健康叶片中无此扩增带。

At the same time, the SEM study shows that gibbsite occurs on the sample surface. At 200 ℃, as dawsonite sandstone is being dissolved authigenic siderite forms. At 300℃, chlorite deposit on parts of the sample surface. The weak solution of dawsonite sandstone at 100℃ and the formation of siderite at 200℃ illuminate that CO2 being in carbonates in the strata can not be released when CO2 phase is adding to the system.

同时，各温度下样品表面均有一水软铝石放射状集合体沉淀。200℃时，随着片钠铝石的溶解有自生菱铁矿生成，300℃时样品局部有绿泥石沉淀。100℃下片钠铝石的微弱溶解及200℃下菱铁矿的形成表明，在地层条件下以碳酸盐矿物形式捕获的CO2，不会由于CO2的二次注入而重新释放。
