Depth profile acquired with aes has shown that excellent emission character owns to the yielding of the surplus la. analysis the active element concentration on the mo - la2o3 - sc2o3 cathode during it heated. results show la and o diffuse rapidly above 1000 ?, but diffusion rate of o gets slow above 1250 ?, so surplus la maybe produce at this temperature
而在高於1250時，鑭含量依然上升，而氧含量變化已經不大，故可以認為這是超額鑭生成的溫度，元素鈧在從800加熱到1290 ，其含量基本沒有變化，說明在這種材料中，鈧元素向表面的擴散不明顯。 -
The significance about this paper was expressed. chapter 2 is the main body of the paper, we estimated and calculated the survival probability of a two - insurance risk model ; we acquired the expectation of maximal aggregate loss and the distribution of the supreme surplus before ruin ; at the same time, we discussed multi - insurance risk model in brief. in chapter 3 we briefly reviewed the whole paper and put forward the further tasks
第一章緒論部分對風險理論及其發展作了回顧，說明將經典風險模型推廣到多險種風險模型的意義所在，並介紹了兩種典型的處理方法和獲得的主要結果；第二章是主體部分，詳細探討了兩險種風險模型生存概率的估計及計算，並得到了保險公司最大損失的一階、二階矩和破產前最大余額分佈，同時也簡略討論了多險種風險模型；第三章對全文作了回顧，提出下一步要做的工作。
