分别采用 XRD 和 SEM 对锂硼合金进行了测试，结果显示锂硼合金为锂硼化合物和自由锂组成的双相结构。采用溶样、加热、过滤、清洗的新方法处理样品，取过滤清液酸碱中和滴定测试了样品中的总锂含量，并探讨了影响测试结果的几个主要因素。尝试在全程氩气保护下，采用 DSC 方法测试样品200℃附近的吸热数据，通过计算得到合金中自由锂含量。
分彆採用 XRD 和 SEM 對鋰硼閤金進行瞭測試，結果顯示鋰硼閤金為鋰硼化閤物和自由鋰組成的雙相結構。採用溶樣、加熱、過濾、清洗的新方法處理樣品，取過濾清液痠堿中和滴定測試瞭樣品中的總鋰含量，併探討瞭影響測試結果的幾箇主要因素。嘗試在全程氬氣保護下，採用 DSC 方法測試樣品200℃附近的吸熱數據，通過計算得到閤金中自由鋰含量。

Li-B alloys were tested by XRD and SEM,the results showed that Li-B alloys were two-phase structure composed of lithium-boron compounds and free-lithium. Samples were processed by a new meth-od of dissolving,heating,filtrating and cleaning. The total lithium content was tested using the method of acid-base titration. Several major factors that affect the test results were discussed. The endothermic peak around 200 ℃ was tested by DSC under argon protection,and then the free-state lithium content was cal-culated.
