The results shown that the β-Zr's forming in the electronic beam alloying cumbered the diffusing of oxygen, and it improved the corrosion resistance of zirconium alloys. After the Nb ion implanted in Zr-4, ZrO2 and NbN were formed, at the range of 1×10^17 to 3×10^17g/cm^2, with the dose increasing, the capability of corrosion resistance was improved.

结果发现：电子束合金化后形成的β-Zr相阻碍了氧的扩散，提高了合金耐蚀能力；Nb离子注入合金后，注入层中生成了ZrO2和NbN，当注入剂量在1×10^17~3×10^17个／平方分米范围内时，随着注入剂量的增加，耐腐蚀能力增强。

In simulated HLLW Zirconium ion hydrolyzes easily, but other element ions all exist as ion, therefore them hardly adsob on surface of silica xerogel.

在模拟高放废液中，锆很容易水解，而其它的元素离子在酸性条件下，均以离子形式存在，因此很难在SiO〓干凝胶的表面上吸附。

In this present work, we have synthesized three types of solid superacid with different structure of molecular sieves by sulfating zirconium silicalite molecular sieves, namely SO〓/Zr-ZSM-5, SO〓/Zr-ZMS-11 and SO〓/Zr-HMS.

本研究中，我们通过硫酸促进锆硅分子筛的方法，合成出了三种具有不同分子筛结构的固体超强酸催化剂，即SO〓／Zr—ZSM—5，SO〓／Zr—ZMS—11和SO〓／Zr—HMS。

In the orthogonal designable experiment ,the analysis results of zirconium source, precipitation , the sulfating agent is 1.54%, 2.27%, 5.11%,respectively. This result show that the influence of sulfating agent to the catalytic activity is the biggest. Under the same density of the sulfuric acid soaks, the effect of sulfuric acid is well compared to ammonium sulfate .The second is the precipitation, but the influence of the zirconia source is the smallest.

正交设计实验中锆源、沉淀剂、硫酸化试剂的极差分析结果分别为1.54%，2.27%，5.11%，此结果说明硫酸化试剂对催化剂的影响最大，其次是沉淀剂，锆源的影响最小，同时表明以Zr(NO3)4·5H2O为锆源、乙胺为沉淀剂、硫酸为硫酸化试剂是催化剂的最佳制备方案。
