The scale formed on pure Ti is exclusively TiO2 regardless of temperature, while the scales formed onTi3Al and Ti3Al+TiAl were duplex and always spalled after cooling, consisting of the outer-layer of most TiO2 and the inner-layer of most TiO2, Al2O3, and minor Ti(subscript 1-x)S. The formation of Al2O3 is responsible for the reduction in the corrosion rates of Ti-Al alloys as compared to those of pure Ti.

纯Ti在800～1000℃的腐蚀生成物皆是TiO2，而Ti3Al和Ti3Al+TiAl则形成两层易剥落的腐蚀物，包括外层的TiO2，及内层多量TiO2和少量的Al2O3和微量的Ti(下标 1-x)S，其中，Al2O3的生成是造成Ti3Al和Ti3Al+TiAl合金腐蚀速率较纯Ti为低的主因。

The morphological analysis and chemical characterization of the worn surfaces via scanning electron microscopy, laser scanning microscope, and X-ray photoelectron spectroscopy reveal that under titrimetric water lubrication, the hBN in Si3N4-hBN spalled off during the wearing tests and the spalled pits formed on the wearing surface of Si3N4-hBN, and then the debris dropped into the pits to react with water, thus a tribochemical film formed on the wearing surface. The formation of the tribochemical film facilitated smoothing the surfaces of Si3N4-hBN and Si3N4 to create a fine lubrication environment.

在滴定法水润滑条件下，磨屑不易被水带走，当Si3N4-hBN与Si3N4配副摩擦时，由于Si3N4-hBN摩擦面上hBN偏聚区域发生脆性断裂和剥落而形成剥落坑，磨屑在剥落坑中堆积并氧化、水解，反应产物富集于剥落坑中，进而在摩擦表面形成含B2O3和SiO2的摩擦化学反应膜，从而保护了Si3N4-hBN和Si3N4摩擦面，使其变得光滑，为发生流体润滑提供了条件。

沉积复合OTFC试样的氧化层形貌有如下特征：(1)氧化层绝大部分致密、完整、与基体附着良好，晶粒细小（图7a，7b）；(2)在短时间(15s)沉积2O3 OTFC试样的局部表面出现了不均匀氧化（图7c，7d），但只是在沉积Cr/Y=4/1膜试样的局部表面产生了类似无涂层Fe25Cr上剥落的厚膜（图7d）；(3)沉积2O3(Cr/Y=2/1) 60s（图7e）与15s（图7c）的结果不同，前者整个试样表面氧化产物颗粒细小，无粗大氧化物颗粒形成；(4)沉积2O3(Cr/Y=2/1) 60s和2O3(Al/Y=3.6/1)薄膜的试样由于氧化增重非常少，氧化层很薄，刻印着涂层中局部出现的裂纹（图7e，7f），这种印迹的保留可能反映着传质机制的改变，即新氧化物由在外表面形成转变为在外表面以下形成。

With the development of embryo, Myf5 expression decreased gradually in somites in the anterior region, but remained strong in the newly formed somites; After 30 somites formed, MyoD expression decreased in the somites except the caudal somites. At the hatching stage, MyoD and Myf5 were expressed in head muscle cells and fin muscle cells. In the growing fish, Myf5 was expressed in the skeletal muscle and intestine, and in adult flounder, Myf5 was only expressed in muscle. In the growing fish and adult fish, MyoD was only expressed in muscle.

It is the soil mass maintained by the umbrella-shaped root system of trees during the geological history,and it is formed by the interactive compression of tree load and growth of main root system and by the differential compaction of surrounding soil mass;in other words,it also is a kind of the sedimentary textite or sedimentary structure formed under the influences of biological process.

The results show that the white thick-bedded siliceous rocks have high contents of SiO2 and Al2O3 and high ratios of Al/ and Al2O3/(Al2O3+ Fe2O3). The ∑REE are low, and the North American shale-normalized REE patterns are characterized by enrichment of LREE and absence of Eu and Ce anomalies, which suggest that the white thick-bedded siliceous rocks might have been formed in the continental margin environment and affected significantly by terrigenous constituents. The anatase-rich siliceous rocks have high contents of TiO2, Fe2O3, Cu and V but low Al/(Al + Fe+ Mn) and Al2O3/(Al2O3 + Fe2O3) ratios. The ΣREE are high, the North American shale-normalized REE patterns are obviously characterized by left-oblique to flat styles of curves and slight negative Ce anomalies, implying that they might have been formed in an oceanic ridge environment.
