沉积

Saline lake sediments are characterized by multi-stage and long period of salt formation, continuous sedimentation and cyclicity of salinization-desalinization, so they are one of the important research objects with respect to the reconstruction of paleoclimate and the study of global change.

The Ordos craton basin was relatively stable- featured in the following aspects, such as the lithosphere texture, thermal flow, subsidence /sedimentation, and tectonic evolution.

鄂尔多斯克拉通有其稳定的一方面，表现在岩石圈结构、沉积沉降、热流、构造的相对稳定，不仅在克拉通层序的构造沉积稳定，在后期仍然表现为相对稳定。

As stream sediments in the forest-covered area have a high content of organic matter, this study chose the coarse fraction stream sediments, which could easily exclude the impact of organic matter.

森林覆盖区水系沉积物中，有机质含量较高，选择较粗粒级水系沉积物，可有效排除有机质的影响。

The DLC film deposited at substrate temperature of 100℃ shows the best integrated property with carbon content of sp〓 bonding state up to 40% which is two times more than that in the films prepared by Americans with the same method. Accordingly, the microhardness is up to 30Gpa, and friction coefficient and optical band gap decrease to 0.10 and 1. 76eV respectively. It is found that sp〓C content in DLC films decreases with the increasing substrate temperature in the process of film deposition, especially after 300℃.

当基片温度为100〓C时沉积的DLC薄膜的综合性能最好，此时沉积的DLC薄膜中sp〓C含量最高，达到40％多，是美国学者用同种方法所得结果的2倍；由于薄膜sp〓C的含量高使得其显微硬度达到30GPa，摩擦系数最小为0.10，光学带隙最宽为1.76eV。

Further, many hand-dug wells and oil seeps exist in the area, which suggests the presence of a favorable oil and gas movement zone worthy of exploration.

为了研究该区的勘探方向，笔者从区域构造和沉积演化入手，分析研究了该区的生油层、储层和盖层的沉积相带特征和有利的油气聚集带。

This is that people with a single copy of the gene for Tay-Sachs, or that for Gaucher's, or that for Niemann-Pick should be more intelligent than average.

不过，该理论也有令人信服的地方：它对于拥有单份泰萨二氏病或脑苷脂沉积病或神经鞘磷脂沉积病基因的人会比普通人更聪明做出了明确而可检验的预测。
