Being controlled by the rheology of the lower crust, erosion may level off the topography, and can break the balance of kinetics and thermodynamics inside of the crust therefore rebuild the structure and component of the curst. the uplift process of the mountains is then enhanced; we believe that the rate of the exhumation is controlled by both the uplift of orogen and the outer spheres of the earth.

在下地壳物质层流变作用机制的调节下，地表剥蚀作用并不仅仅是传统意义上地表夷平的因素，它还能打破地壳动力学和热力学平衡，引起地壳内物质和结构的重置，进而促成山脉的加剧隆升；地表剥蚀作用的强度既受控于造山带的抬升，也受制于地球外圈层。

They contain a substance called cyanogen glycoside the red apples contain more of this substance and it is pretty easy to consume a fatal dose.

The gasification efficiency increased and the molar fraction of H2 decreased with an increase in the reaction temperature. The decomposition of PVA was more complete at higher temperatures. At 24 MPa, 500℃ and 120 s, the TOC remove rate, the carbon gasification rate and the hydrogen gasification rate were up to 71.46%, 67.97% and 157.24% respectively. A change in the residence time had no significant effect on the molar fraction of gas production but an increase in the residence time could enhance the gasification efficiency of PVA. It was found that the intermediates were mainly alkane, cycloparaffin, aromatic hydrocarbons, and low-molecular weight acids. It was supposed that PVA was degraded into small molecules through breaking of C-C bonds. Parts of the molecules were converted into H2, CO, CH4 and CO2 while some was converted into aromatic hydrocarbons.

过程探索发现：反应温度的升高能提高PVA气化效率，但气体产物中H2的含量随反应温度的升高有所下降；随着反应温度的升高，PVA分解趋于彻底，在压力24MPa、温度500℃、停留时间120s的条件下，TOC去除率、有机碳气化率和氢气化率分别达到71.46%，67.97%和157.24%；停留时间的变化对气体产物含量没有明显的影响，但延长停留时间能提高PVA的气化效率；PVA气化反应中间产物主要为链状烷烃、环烷烃、芳香烃及小分子酸，根据中间产物出现的顺序推测PVA的降解为由C-C键断裂形成小分子物质，这些小分子物质一部分转化为H2，CO，CH4和CO2，一部分形成难降解的芳香族化合物。
