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 diffusion of mass or heat across two phases is extensively involved in chemical processes. Because of the effect of this kind of diffusion, there will be a inhomogeneous distribution of material concentration and then a gradient of interfacial tension will be occured on the interface of the two phases. When the gradient tends to a certain value, the natural convection would be induced derivatively, and orderly convective cells would appear in the system simultaneously. This is the so-called Marangoni phenomenon.

在化工过程中，广泛涉及到两相间的质量或热量扩散，由于这种扩散的作用，将在相界面处产生物质浓度的不均匀分布，从而出现界面张力梯度，这种梯度达到一定值以后，将出现派生的自然对流运动，并且在系统中呈现有序的对流胞结构，这就是所谓的Marangoni现象。

The formation and evolution of the graben includes initial fault depression,main fault depression and renew action three stages.

地堑在形成过程中，由于边界断裂的限制造成应力不均匀分布，导致地堑内部东西差异沉降和南北隆凹相间，沉降中心和沉积中心随着断裂活动期次的不同而发生迁移。

The energy deposited by the particles can transfer directly or indirectly along DNA strand and the bonds of high affinity and low ionization potential respond firstly. As a result, the strand breaks and uneven distribution of breaks is formed.

原因可能在于沉积的能量直接或间接沿DNA链迁移，链上相对较弱的化学键优先产生反应，并最终导致链的断裂，从而引起断裂的不均匀分布。
