3.2.1.1 Melting point Melting point is a valuable criterion of evaluation of any changes in the structure of an organic compound. The formation of prodrug is characterized by a change in melting point which is
Thermal motion analysis, packing energies and MD simulations on minicrystals indicate the importance of both enthalpic and entropic factors in the melting behaviour of the two isomers. The higher melting point of the meta -isomer could originate from both a smaller Δ S f and higher Δ H f ...

14.The robots in the study were made from gallium, a soft metal with a low melting point of 30 C. 该研究中的机器人由镓制成,镓一种软金属,其熔点低至约 30 摄氏。 「21世纪英文报」 15.Like Sodium it'ss quite a low melting point metal. 就像钠一样, 它一种熔点很低的金属。机翻 「趣...
The eutectic point of a melt is the point at which the composition of the components is exactly in a state that both constituents solidify from the melt directly. This point lies below the melting point of the single alloy constituents due to crystallization hampering. For noneutectic ...
At a critical point when the intrinsic three-fold symmetry of the hydrodynamic interaction matches that of the hexagonal crystal, the system produces a monkey-saddle van Hove singularity (vHS)19,20,21 with a nearly flat band of slow collective excitations that induce a much sharper melting ...

Again, in huge contrast, the higher tip temperature setting of 370 to 450 degree Celsius is mandatory for thosehigh melting pointLeadFree materials. asahisolder.com asahisolder.com 再次,通过 强烈的对比,当那些高熔点无铅材料被用于点焊时,焊接棒的最高温度设置是有必要在 370 —450 摄氏度的。
Induction heating allows you to raise and hold the temperature of your material to its melting point without the use of flame or arc. A non-conducting crucible holds the charge of material to be melted while the induction coil induces eddy currents in the charge material, raising the temperatur...
