求翻译：主要是因为在热处理淬火的过程中冷却的降低程度无法超过电弧熔炼时样品从熔融态转化到室温的速度，使得无序的D相有序化，对磁致伸缩造成了影响。是什么意思？

Reduce the degree of cooling in the heat treatment and quenching process can not exceed the arc melting the sample transformation from the molten state to room temperature, the speed, making the disorderly d phase ordering, had an impact on the magnetostriction.

Mainly because of the heat-treated hardened in the process of reducing cooling could not be more than an arc when smelleding samples from molten into a room temperature of the speed at which the disorder is an orderly D of magnetostrictive had an impact.

Mainly is because cools reduces the degree to be unable to surpass the electric arc smelting the sample when in the heat treatment quenching process to transform from the molten to the room temperature speed, causes disorderly the D ordering, has had the influence to the magnetostriction.

Mainly because as in heat treatment and quenching of cooling of the lower levels cannot exceed the arc-melting samples from the speed of conversion to room temperature molten, made of disordered d-phase order, caused by magnetostriction effect.
