实验结果表明：在超临界压力区域，倾斜光管内可能由于受到热加速度和浮力的综合作用，倾斜光管传热特性沿周向是不均匀分布状态，通常管内顶部的壁面温度比底部高，在大比热区发生传热恶化和传热强化的现象，低质量流速和高热负荷条件下会发生传热恶化现象，高质量流速下会发生传热强化，避免壁温发生飞升；内螺纹管内的传热特性在不同焓值区域表现不同，在远离拟临界焓值的低焓值区域和高焓值区域，呈现出相似的规律，而在接近拟临界焓值区域时，传热得到强化。

The results show that dynamic softening is easy to occur in these ingots and flow stress becomes steady finally; the material constants of hot deformation are procedural parameters that stress-level coefficient α, strain rate sensibility exponent m and deformation activation energy Q are all increased with strain increasing, while stress exponent n is decreased gradually; the values α and m of the alloy homogenized are the biggest and the value n is the smallest, dynamic softening effect of the alloy is the most obvious, which can deform evenly; influence of strain on the value Q of the alloy homogenized is a little and the average value of Q is only 176.5kJ/mol, so the alloy is easy to deform; the alloy matrix shows the regular recrystallization grains when the strain is 50%; dislocation cell structure re-formed in the grains with increase of strain.

结果表明：经不同处理的Al-1Mn-1Mg合金均易发生动态软化并最终呈现稳态流变特征；热变形材料常数是过程量，随应变量的增加，应力水平参数α、应变速率敏感性指数m和热变形激活能 Q 随之增大，而应力指数 n 则逐渐减小；均匀化退火后，铝合金的α和m值最大而n值最小，动态软化效果最明显且变形均匀，在该状态下，铝合金的 Q 值受变形量影响小，平均仅为176.5kJ/mol，易进行热变形；当应变量为0.7时，基体呈现规则的再结晶晶粒组织，随着应变量的增加，晶内重新形成了位错胞结构。

Schorl in the granite and dravite in carbonatite are respectively related to the magmatic fluid and basin fluid, while the tourmaline with optical and chemical zones in vein ore is mainly due to the mix of post-magmatic hydrothermal solution and basin fluid; The chemical composition variety of garnet in the horizontal zones are mainly related to the post-magmatic hydrothermal solution and the accessorial fluid from sedimentary basin.

不同产状的电气石及其环带状结构分别与来自岩浆期后热液和盆地流体及其混合所产生的"化学振荡"作用有关；在夕卡岩水平分带中，石榴石化学成分的变化除与岩浆热液在演化过程中自身的物理-化学条件发生变化外，可能还与岩浆热液在对围岩进行渗滤交代的过程中有盆地流体的加入有关。

这速度远比发生热化学反应的热化学重要。

Experiment results show that though the grains of the heat-affected zone are seriously coarsened due to the effect of welding thermal cycle, there is no softened zone and the strength of the welded joint doesn′t decrease because the transformed microstructure is different from the original one.

结果表明：经过焊接热循环的作用，虽然热影响区的晶粒明显粗化，但由于所获得的二次组织形态与钢筋原始组织不同，热影响区未发生软化，也不存在焊接接头强度下降的问题。

The δ〓O for both of them are changed due to water/rock interaction at water/rock weight ratios of larger than 0.1, and the calculation indicates that, in this case, the influence of water/rock interaction on the δD value of the fluid is minor. In the upper part of the geothermal system, the upward ore forming fluid mixes with low temperature groundwater with very low salinity and δ〓O, which may cause the precipitation of metals.

根据氢、氧同位素研究结果，嵩溪银锑矿床的上升成矿流体是由岩浆热液与循环地下水热液混合而成，这种混合成因含矿热液上升到地热系统上部与低矿化度、低δ〓O的低温地下水发生了不均匀混合，这种混合作用导致金属矿物沉淀，但成矿物质是由上升成矿流体带来的。
