The influence of V and Cr content on the hydrogen storage properties of TiVCr based alloys was investigated. The desorbing plateau pressure of the alloys decreased slightly and the capacity of absorption and desorption increased slightly with increasing V content.

为此研究了钛钒铬基合金中V、Cr含量对贮氢性能的影响，结果表明：随着金属元素V含量的增加，合金的放氢平台压力略有降低和吸放氢量略有增大。

The nanocrystalline alloys desorb H2 at 493K and under pressure of 0.1MPa rapidly. Mg1.80Ti0.20Ni0.8Cr0.2 alloy desorbs 2.17% H2 in 18min at 493K.

在493K， 0.1MPa条件下可快速放氢， Mg1.80Ti0.20Ni0.8Cr0.2在18min内便可完成放氢过程，总放氢量为2.17%。

On the other hand, fertilizer of CaHPCu is cheap and the high degree of purity (the content of P_2O_5 is 27 -30%)can improve phosphorus in soil, reduce production cost and promotes agricultural effectiveness. The content P in CaHPO_4 slow release in calcareous soil. Besides, the addition of HA activates phosphorus in CaHPO_4 and in soil, increases organics in soil, which promotes crops quality and yield.

一方面由于磷酸氢钙的纯度高，与过磷酸钙相比重金属等杂质含量较少，能有效减少对土壤及水体的污染；另一方面磷酸氢钙价格低廉，P_2O_5，含量可以达到27～30%，在石灰性土壤中本身就是一种缓效磷；腐植酸的添加，活化了磷酸氢钙中的枸溶磷，同时可能改善了土壤团粒结构，为作物优质、高产奠定了良好的基础。

We obtained similar results from the non H-exposed Cl sample. By plotting the Arrhenius relations we were able to obtain the activation energies for each set. From the set with H-exposure we obtained 1.23eV for inter-dimer hoppings and 0.70eV for intra-dimer hoppings respectively, while for the set without H-exposure we obtained 1.14eV and 0.62eV for the inter-dimer and intra-dimer hoppings respectively.

由Arrhenius 关系线，我们推算出氢-氯原子交换运动的动力能障，即对於曝氢而言inter-dimer跳跃的动力能能障为1.23 eV、至於intra-dimer跳耀的动力能则为0.70 eV，相对的，在对於没有曝氢的inter-dimer跳耀的动力能为1.14 eV，intra-dimer跳耀的动力能则是0.62eV。
