The unit bottom was the unconformity developed by Wuling Movement, and the unit top was overlapped by glacial deposition of Nanhua System. What\'s more, an unconformity can be found in Northern Guizhou and North-western Hunan. At the same time, this boundary was an important transformation between different deposition types: Banxi Group was rift basin deposition with flysch suite, and bearing a vast amount of pyroclasts, and this suggests that there was strong activity of crust. But the overlapping glacial deposition stood for steady deposition with penecaprock characteristic, and under unique climate environment.

下为武陵运动形成的角度不整合面所限；其上被南华冰期沉积所超覆，在黔北—湘西北可见角度不大的不整合，而且这一界面是两个不同沉积类型或建造之间的一个转换：板溪群为具有复理石韵律的裂谷系充填，其中发育大量火山碎屑沉积，显示较强的地壳活动性；而上覆的南华冰期沉积所代表的是一个具有准盖层性质的、独特气候环境下的稳定沉积。

The thicker the DBL is, the stronger the inhibition will be. Thus, the presence of DBL in a polder reservoir can result in a delay of natural clearing process of polluted water. The effect of salt release from deposited sediments on the water quality will be a long lasting process.

另外，由于扩散边界层的存在，限制了水动力对沉积物与上覆水之间物质交换的增强作用，所以海湾水库沉积物中蓄积盐分对上覆水的影响将是长期的过程。

There are three features in the minibasins induced by gravitational sliding on the slope: the firstly, feature is surface of unconformity developed by onlap on minibasin margins or surface of unconformity truncated by mass transport-complex are sequence boundary in the study area; the secondly , accommodation of gravity flow is controlled by up lift rate and sedimentation rate , and styles of filling in the minibasins are dominated by the interrelationship between the two factors; and the third , there are two stacking patterns that consists of upward of turbidite fan-hemipelagic drape mud or mass-transport complexes-turbidite fan-hemipelagic drape mud.

认为在深水陆坡重力滑动作用所形成的微盆地内，层序边界表现为微盆地边缘上超不整合面或重力流对下伏地层的侵蚀不整合；逆冲构造隆升速率与沉积速率共同控制了重力流可容空间和沉积充填样式；沉积垂向演化以块状搬运复合体一浊积扇－深海披覆泥或浊积扇－深海披覆泥为特征。

The laser-cladding layeron the alloy consists of matrix phase of over-saturation solid solution γ and complexhexagonal carbide M_7C_3. Under certain condition, with fast laser scanning speed, the oversaturation solubility of elements increases in γ, and the precipitation of the complexcarbide M_7C_3 decreases, so that the microhardness increases and the wear resistance de-creases. But at slower laser scanning speed, more complex carbide M_7C_3 may precipitate, andthe wear resistance may be improved. Therefore, it is believed that the principal factor in im-provement over wear resistance is the precipitation of carbide M_7C_3, while overmicrohardness is the over-saturation solubility of elements in matrix phase.

表明：(1)激光熔覆合金层是由过饱和的γ基体相和复杂的六方M_7C_3碳化物相所组成(2)在其他参数不变的情况下，随激光扫描速度的提高，γ基体相过饱和度增大，而析出的碳化物含量减少，因而合金层的硬度升高，耐磨性有所下降；而降低激光的扫描速度，碳化物M_7C_3析出增加，有利于提高合金层的耐磨性、因此碳化物M_7C_3析出量是提高耐磨性的主要因素，而增加基体相γ的过饱和度则是硬度提高的主要因素

There was an obvious phenomenon of mechanical occlusion on the cold spray coating interface, and the rolled coating had the phenomenon of metallurgical bonding; The structure of cold-sprayed coating is dense. The poriness of the cold-sprayed coating gradually reduce as the coating's thickness increase.

结果 涂层界面形貌的不同反映出两种涂层的结合机理不尽相同，冷喷涂层界面出现明显的机械咬合现象，而轧制涂层以冶金结合为主；冷喷涂层组织致密，孔隙率随着喷涂厚度的增加逐渐降低；冷喷涂层的表面粗糙度高于轧制覆铜板，有必要对其进行一道轧制处理，改善涂层表面平整度。
