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。

Barrel is the key part of artillery. In shot process, propellent gas of high pressure and high temperature flows in the tube at a high rate of speed, which brings an upheaval to the temperature field of the composite barrel. As to the composite barrel with metal inner, its poor thermal conductivity is more likely to cause uneven temperature distribution and bigger temperature gradient, to produce improper deformation and to make the work temperature of metal inner rise, all of which will affect the life span of barrel.

身管是火炮的关键部件，在火炮发射过程中，高温、高压的火药燃气在身管内成脉冲式高速流动，使身管受到急剧的加热，引起身管壁内的温度急剧变化，而对于带金属内衬复合材料身管，由于复合材料导热性能较差，更容易引起非均匀温度分布以及较大的温度梯度，产生不合适的变形，也会使身管的金属内衬的工作温度升高，从而使得身管的寿命降低，同时身管的发热会引起其刚度的变化，增大射弹散布。

Respectively, both of structural features and rocks have the features of multiple phase's of deformation.

The viscosity properties of break flour, middling flour, and oat flour (mixture of break flour and middling flour with nature milling ratio) were investigated. The results showed that after high-temperature treatment, the average gelatinization temperature of break flour, middling flour and oat flour decreased significantly, which were lower than that of oat without high-temperature treatment. Their peak viscosity, final viscosity and hold viscosity increased both under air-heating (140℃, 155℃) and far-infrared heating (200℃), compared with non-treated samples. With the temperature of high-temperature effects treatment increasing gradually, their viscosity properties decreased.
