In this paper the thermal properties of Al-Cu-Ce alloy with different composition were measured by differential scanning calorimeter(DSC). The results show that with increasing Ce content in this alloy the heat of fusion increases, DSC curves change accordingly, solidus temperature increases slightly, while the liquidus temperature decreases.Vertical Bridgman-Stckbarger technique was employed for carrying out the investigation, and molten alloy was solidified under a wide range of conditions.

In this paper the thermal properties of Al-Cu-Ce alloy with different composition were measured by differential scanning calorimeter(DSC). The results show that with increasing Ce content in this alloy the heat of fusion increases, DSC curves change accordingly, solidus temperature increases slightly, while the liquidus temperature decreases.Vertical Bridgman-Stckbarger technique was employed for carrying out the investigation, and molten alloy was solidified under a wide range of conditions. In order to reveal the morphology of the growing interface, specimens were quenched into cooling liquid metal after solidified to a certain degree. It shows that with the increasing Ce content in the alloy, the planar solid-liquid interface tends to breákdown with the appearance of holes and depressions, and the morphologies of cell and dendrite also become irregular which further branch out and narrow the secondary arm spacing between them.Distribution of solute in liquid and solid near the interface was determined by means of electron-microprobe technique. Results show that with the increasing of Ce content in the alloy the concentration gradient of Cu solute and concentration of Ce in liquid near the interface increase, while the partition ratio of Cu in the alloy decreases.Based on the experimental facts and the kinetics of interface stability the authors further proposes the possible role of Ce in Al-Cu alloy during solidifcation.

本文论述了Al-4.5%Cu合金在定向凝固条件下,铈对其固液界面形态和稳定性的影响。结果表明,铈使铜的分配系数减小,合金的熔化潜热增加,固液界面前沿成分过冷和溶质的不稳定扰动增大,因而导致合金生长稳定性下降,平面-胞晶-枝晶生长方式转变加速,二次枝晶间距减小。

In this test the seeds from 126 provenances were collected thoughout masson pine's distribution area and planted in the province's five sites with an uniform design. The phenotype data in seed, seedling and young tree stages were recorded through observations and measurements for a period of six years, and then five physiological characters and peroxidase isozyme of seedling were analysed. Three analyses of the data obtained were made, i.e. the univariate variance analysis of characters, correlation analysis...

In this test the seeds from 126 provenances were collected thoughout masson pine's distribution area and planted in the province's five sites with an uniform design. The phenotype data in seed, seedling and young tree stages were recorded through observations and measurements for a period of six years, and then five physiological characters and peroxidase isozyme of seedling were analysed. Three analyses of the data obtained were made, i.e. the univariate variance analysis of characters, correlation analysis of characters with latitude and longitude, and path analysis of main traits with meteorological elements in the place from where the seeds were collected. The results suggest that masson pine populations show characteristics of latitude-oriented variant model. After analysing and systhesizing of the data of eight to twelve characters from two sites by means of principal component analysis (PCA) and systematic mean cluster analysis, it is concluded that the provenances of masson pine could be divided into three zones and four districts. By using five traits including growths and adaptabilities as distiction factors and analysing stabilities of seed sources in high growth, some suitable provenances were chosen for different ecological regions represented by the five plantations.

本试验共收集马尾松分布区内126个种源的种子,在浙江省内五个具代表性的试验点采用统一设计营造试验林。经6年的观察和测定,取得种子、苗木和幼林期的表型资料。对获得的资料进行性状单因素方差分析,性状与纬度、经度的相关分析,主要性状与产地气象因子的通径分析。结果认为,马尾松具有纬向倾群变异模式。对8—12项性状进行主分量分析,并运用类平均法作系统聚类,综合2个试验点的聚类结果,提出马尾松种源可划分为3个带4个区。选取生长、适应等五个性状作判别因子,结合高生长稳定性分析,为省内各试验点代表的不同生态区初步评选出适生的优良种源。
