Effects of dry temperature and dry time on properties of heat cured sand and the relationship with binder composition are as follows:sands bonded by binders that are not modified have high strength when dry temperature is high and dry time is long,but their anti-wettability power is poor . Sands bonded by binders that are modified by B but not modified by M can be dried quickly and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M but not modified by B can also be dried quickly to obtain maximum strength,then the strength becomes lower when they are dried continually for more time. and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M as well as by B at the same time can be dried quickly to obtain maximum strength at low temperature and short time. But the anti-wettability of sand mold is best when they are dried at high temperature and long time.

烘干温度和烘干时间对热硬砂性能的影响及其与粘结剂改性的关系是：未经改性剂B和改性剂M改性的粘结剂砂，脱水速度较慢，烘干温度越高，时间越长，则硬化强度也越高，但未经改性的粘结剂热硬砂的抗吸湿性较差；经改性剂B而不经改性剂M改性的粘结剂热硬砂，烘干硬化速度较快，强度也高，但在高湿度下的抗吸湿性不好；经改性剂M改性而不经改性剂B改性的粘结剂热硬砂，烘干时强度先随烘干时间升高至最大值后，继续烘干时强度又出现下降；经改性剂B和经改性剂M共同改性的粘结剂热硬砂能在短时间和较低的烘干温度下就可烘干到最高强度，即烘干脱水的速度较快，但试样的抗吸湿性差，若在更高温度和更长时间下烘干，试样的抗吸湿性得到改善，综合考虑烘干强度和抗吸湿性要求，对于φ30×30mm试样，理想的烘干温度是200℃，烘干时间20分钟。

The phenol resins and plastics were the original synthetic thermosetting materials.

酚树脂和塑料是原始的热硬化性合成材料。

A clear thermosetting resin made from urea and formaldehyde and used in electrical fittings, adhesives, and finishes.

一种清亮的热硬化性树脂，由尿素和甲醛制成，用于电器装备、粘合剂和末道漆中。

Research shows : laser treatment, the hardening layer from the melting zone, transformation hardening and the heat-affected zone, organizations to small uniform martensite, have a high density of dislocations, which are high hardness and wear resistance of the main reasons.

研究表明：激光处理后的硬化层由熔凝区、相变硬化区和热影响区，组织为细小均匀的马氏体，产生了高的位错密度，这些是硬度和耐磨性高的主要原因。

As a result of the coaction of abovementioned factors, the bainite has superior secondary hardening effect, thermal strength and structural stability to martensite formed by straight tempering.

以上诸因素的共同作用，使贝氏体具有比直接淬火所获得的马氏体更高的二次硬化效应、热强性和组织稳定性。

This also results in a saving in material, because trimmed-of gates and sprues would be a complete loss of the thermosetting plastic.

这也在材料中造成储蓄，因为清理浇口和浇道会是热硬化性的塑料性物质的一个完全损失。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
