  1. Cd元素对合金熔程、抗拉强度的影响最大,Sn元素次之,Pb元素的影响最小。

    The influence of alloy elements on the melting range and tensile strength are reduced in the order of Cd , Sn and Pb .

  2. 结果表明:(AgCu28)80In11Sn9合金具有较低的固相线温度和熔程、简单的物相结构、适中的铺展率。

    The results show that ( AgCu_ ( 28 )) _ ( 80 ) In_ ( 11 ) Sn_9 alloy has a low solidus temperature and melting range , a simple phase structure and a moderate spreading ratio .

  3. PTT环状低聚物的熔程为92.3~222.6℃,熔融后是无色、透明的低粘度液体。

    The cyclic oligomers melt at 92.3 ~ 222.6 ℃, providing liquids of low viscosity .

  4. 结果表明:大部分成核剂的加入对尼龙66熔点影响不大,而熔程ΔTm、结晶度和熔融熵降低;结晶峰值温度Tc升高,过冷度ΔTc和半高宽D降低;

    The results showed most nucleating agents made the fusion range Δ T m , crystallinity and melting entropy decreased , while the crystallization temperature increased , the degree of supercooling and width at half-height decreased .

  5. 熔程缩短,有利于在钎焊过程中形成可靠的连接焊点。

    Shorter melting zone indicated that reliable soldered joints can be formed .

  6. 模具温度高,熔化起始温度高,熔程窄;

    The higher the mold temperature , the higher the initial melting temperature and more narrow melting range ;

  7. 用示差扫描量热法熔融(结晶)峰的正规半峰宽(△T(0.5)~N)表征了共混物的熔程和结晶规整性。

    The melting period and crystal regularity were characterized by the half normal width of the melting peak or crystallizing peak (Δ T0.5N ) .

  8. 以市售石蜡为原料用尿素包合法制得了具有合适相变温度(熔程在26~26.6℃)的石蜡。

    The paraffin with appropriate phase transition temperature ( from 26 ℃ to 26.6 ℃) was separated from the paraffin on sale by the urea adduct method .

  9. 同时,降凝剂使得系统的热性能&溶解焓和溶解熵均发生了改变,原油中石蜡的熔程变长,相变能变大。

    At the same time the thermo-performance-dissolve enthalpy and dissolve entropy of the system were changed by PPD which made the wax molten time longer and phase shift energy larger .

  10. 相同组成的共混物从玻璃态结晶比从熔体结晶所达到的结晶度高,但起始熔融温度低,熔程宽,表明生成较多的不规整的微晶体。

    It is also noted that with the same composition , the crystallinity of PET in the blends formed from the glassy state is higher than that formed from melt but the former has lower onset temperature and more broad range of melting .
