### Dendritic Crystal Growth Evolution of Al-2.6Cu Alloy under Different Supersaturation Conditions

In this paper, dendritic crystal growth evolution of Al-2.6Cu (at.%) alloy are investigated by using the phase-field model coupling concentration field equations under different supersaturation conditions. The calculated results indicate that the supersaturation, which is larger in lower initial temperature, plays a very important role in dendritic crystal growth and microsegregation. With the initial temperature decreasing and supersaturation increasing, secondary branches change from sparseness, thickness, and disappearing. The larger supersaturation causes higher faster dendrite growth velocity and solid phase ratio. The change of microsegregation degree is correspondingly complicated. When initial temperature is higher than 829K, the microsegregation degree increases. When the initial temperature lower than 829K, the microsegregation degree reduces rapidly. The simulated results agree well with the solidification theory.

Directional solidification microstructure of Bridgman system was simulated using phase-field method, and different pulling velocity calculated results were obtained. When the pulling velocity is 0.08 cm/s, the columnar crystals competitively grow. The space between columnar crystals is the biggest. When the pulling velocity is 0.90 cm/s, the columnar crystals become thinner and competitively grow all the time, and the microsegregation is bigger. When the pulling velocity is 1.60 cm/s, planar interface comes back, and solute trapping takes place. The columnar crystals become much thinner, and microsegregation decreases. When the pulling velocity is 1.80 cm/s, the grain boundary of columnar crystals becomes unconspicuous, and the degree of microsegregation approaches 1. At the same time, the transverse solute profiles is also studied in this paper.

### Impacts of Derivatives on Firms’ Value Empirical Results from Chinese Companies

There is no common understanding for the realm of theory and practice to understand correctly whether financial derivatives are used effectively in China today and how the derivatives influence firm value. This paper sorts out literatures of related derivatives and company value, takes 119 listed resource-type companies as the research samples with the data of 2007-2010, and tests empirically the impacts of derivatives upon the firm value. The research results show that the application of derivatives improves the company’s Tobin’s Q, but has negative effect on ROA and is not significant to EPS and cash flow. This means that though the use of derivatives produces negative effect to the profit margin, but at the same time it is conducive for the company to enhance its value, illustrating the use of derivatives is generally effective. This conclusion provides valuable reference for the derivatives of the decision and management of enterprises, investors and creditors, and is also beneficial to supervision of government and to make related policy.

### The Simulation of Plane Measurement Points

In assessing a flatness error evaluation algorithm, the measurement data is always actual measurement of which the true flatness value is unknown, so that it is hard to directly give the accuracy of the algorithm. In order to judge the quantitative assessment of algorithm performance, this paper presents a simulation method of plane measurement points. First, according to analyze flatness definition and determination methods, the necessary and sufficient conditions for extreme points were proposed. Then error composition for measurement points was analyzed and the mathematical simulation model for measurement points was established .Finally, two sets of simulation measurement points were cited to specify the simulation method for plane measurement points.
