Sb can combine with Cu and P to form a low melting point compound which lowers the melting point of binary Cu-8P eutectic alloy by nearly 200℃. Bi and Cu can create compounds with low melting point(270℃) distributing at the boundaries and that is the reason why the melting point of (Cu-8P)-Bi is lower than that of binary Cu-8P eutectic alloy. The eutectic cluster can be refined with the addition of Fe, and that is the reason why the addition of Fe can decrease the melting point of Cu-8P alloy. Two means of decreasing the melting point of Cu-8P are found.
一定量的Sb与Cu, P形成低熔点相,从而大幅降低了Cu-8P合金的熔点,使其熔点降低近200℃;加入少量Bi后, Bi与Cu在共晶团晶界上形成熔点为270℃左右的低熔点化合物,且Bi的加入明显细化Cu-8P合金共晶团,从而使Cu-8P合金的熔点降低;加入Fe能明显细化Cu-8P合金的共晶团,使层片间距由8μm减为2μm以下,并使共晶团由层片状向短棒状转变,虽然Fe与Cu形成熔点为806℃的高温相,但Fe的细化作用使得Cu-8P合金的熔点降低,但降低幅度不大。

Atmospherical plasma jet carries to the surface modification of tungsten oxide nanorod. The results showed that the modified use of plasma gas (O2), in the same distance to increase deal with test-chip of the surface then there is the formation of small particles with the trend, and in the higher distance to some deal with test-chip of the trend of the formation of small particles lower. N2 was more significant than that of Ar plasma for surface modification, and the test piece is somewhat part of the surface nano-rods box integration with the formation of small particle side of the box there is scheduling a clear rod-like.

In this paper, the marine soft soil is mixed with 10% cement added with 0.5% NaOH and 0.5% Na2CO3 separately, which form two types of new cement-soils. Comparing with the undisturbed soil and the 20% cement-soil results in that the alkalescence additive can contribute to generate a large number of needle-like, rod-like or fibriform hydrate calcium silicate crystals. The hydrate calcium silicate crystals can inhibit the generation of calcic alum crystal which would bring expansive action. At the mean time, it can separate out hydrate calcium. The hydrate calcium silicate crystals and hydrate calcium constitute the filling and inclusions together among soil particles and on the surface of soil particles, which cut down the interstices of cement soil obviously. Therefore, the soil mass can be reinforced and the intensity can be improved.
