The results indicate that back electromotive force increases with increasing current density and decreases by 0.5 V after adding 2% Li2CO3, the feeding period is 15 min measured by the method of electric potential control. Finally, the Al-Li alloy with the lithium content of 7.93% can be obtained by electrolyzing for 3 h at the current density of 0.62 A/cm^2 and at 680 ℃, and the current efficiency can reach 74.1%.

结果表明，反电动势随电流密度增加而增大，加入2%的Li2CO3可使反电动势降低0.5V；通过控制电位法测得加料周期为15 min：在680℃、电流密度为0.62A/平方公分的条件下持续电解3h，最终制得了理含量高达7.93%的铝锉合金，电流效率可达74.1%。

The theory and application is explained in this paper. Software XMGREDIT5 matching ELCIRC is used to generate unstructured grid, and is considered fit for ocean but rivers. Tidal current is simulated and validated well, and sensitivity of current structure to bathymetry is visible. Affection of wind is qualitatively analyzed here. At the same time the model is improved on as required, like the tidal open boundary which could choose not only long period harmonic constant but also short period harmonic constant and tidal level, and multi-point results and flow field data could be exported effectively with binary results.

本文介绍了ELCIRC的理论及使用；基于其在Linux平台下的软件XMGREDIT5生成全三角形网格并评价其特性，认为XMGREDIT5较适合大范围海域而不适用于河道；应用ELCIRC模型计算了长江口的潮流场并进行验证，结果与实测资料吻合良好，且能较好地模拟出地形变化对水流结构的影响；文中对于风场的影响作了定性分析，同时根据实际需要对模型作了改进，如将仅支持长期资料调和常数的开边界条件改为可选择的短期调和常数边界和潮位边界，使二进制格式结果文件数据输出可以处理多点数据及流场等等。

A new method of obtaining secondary electron yield and secondary Cs〓 ionization probability by detecting target current and primary ion current under Cs〓 bombardment is put forward The dependence of Cs〓 ionization probability on primary ion energy, primary beam current and substrate compositions, as well as the dependence of secondary ion intensity on erosion time during transient period has been studied The mechanisms of secondary ion emission are explained

二、提出了通过测量靶流和一次束流求取Cs〓轰击下二次电子产额和二次Cs〓离化率的方法，实验研究了一次离子能量、束流强度及不同基体对二次Cs〓离化率的影响和瞬态过程中二次离子强度的变化规律，并对发射机理做了解释。

The relationship between barotropic tidal currents and sea level were established for the first 45-day period using the transfer functions and harmonic analysis, and then carry the prediction for the second 45-day period. There is very good agreement between the observed and predicted semidiurnal tidal current, the rms error is less than 3 cm s-1. However, prediction on diurnal tidal current is rather disappointing, the rms error is about 19 cm s-1, suggesting strong baroclinic tidal component may have a significant contribution to the tidal current, which is not registered in the sea level records.

利用转换函数与调和分析两种方法，验证水位预报正压潮流的可行性，将观测资料分为等长的两段时期，藉由第一段时期约45天的正压潮流与水位的关系，预报下一段时期约45天的正压潮流，结果显示半日潮流的观测值与预报值大致符合，其均方根约在3公分/秒以下；但是全日潮流的观测值与预报值的差异大，其均方根最大可达到约19公分/秒，推测其原因为斜压潮分量大而影响潮流，但是不会对水位资料造成影响。
