It is found that there are no obvious corresponding signals related to the Slichter modes claimed by Smylie (1992), Smylie et al.(1993) and Courtier et al.(2000) in the product spectral density estimates. Instead, it is found that there exist 8 common significant spectral peaks in the subtidal band in the product spectral density estimates of the SCG gravity data, which may be related to some unknown global geodynamical or geophysical effects. It is very encouraging that the central periods of three peaks of them are estimated accurately as 4.93438 ±0.00186h, 4.42734 ±0.001159h and 4.09269 ±0.00082h, respectively, and in significant accordance with the eigenperiod of the Slichter modes of the solid inner core expected theoretically by Smith (1976) with only differences of 0.4%,-1.4% and 1.0%, respectively.

初步分析结果表明，在积谱密度估计中没有Smylie(1992)，Smylie等(1993)和Courtier等(2000)发现的与内核平动振荡有关的共振信号，但存在与某些未知的全球地球物理或地球动力学效应有关的8个重要的明显公共谱峰，估计了在这些谱峰附近的重力共振参数，其中三个谱峰的中心周期与Smith(1976)理论预测的固体内核Slichter模的本征周期符合得非常好，二者之间的差异分别仅为0.4％，-1.4％和1.0％。

Ordos basin accumulates various energy resources. Taking the oil, gas, coal and uranium in the basin as subjects, the scientists of China's State "973" multi-energy minerals enrichment project study the scientific issues of interest concerning the coexistence and accumulation of energy minerals in one basin, such as the material base and geodynamical settings the accumulation mechanism and enrichment environment, and the temporal and space distribution and control factors. This interdisciplinary study provides a new perspective on comprehensively understanding energy geosciences.

我国国家&973&多种能源矿产项目的科学家以富集多种能源矿产于一身的鄂尔多斯盆地为研究地区，以油、气、煤、铀为研究对象，探讨能源矿产同盆共存富集成藏的物质基础与地球动力学背景、成藏机理与富集环境、时空分布与主控因素等科学问题，这是通过多学科交叉综合研究能源地球科学的新视角。

Based on the summary of newest progresses of global gravity field models, isostatic models and flexural theory of Hthosphere and making used of global gravity model (UTCSR GRACE/GFZ EIGEN-GRACE), First, I calculate geoidal anomalies with different degrees and orders, isostatic residual geoidal anomalies of Hthosphere and horizontal stress distribution in Chinese mainland and vicinity and make an interpretation with multi-levels isostatic equilibrium. Secondly, combination with surface geology and others geophysical data, I analyze detailed structure of lithosphere within various segments of the central orogenic system, respectively. Then, On the basis of making a comparative analysis with among East-Asian tomography, anomalies of geoid and satellite magnetic field for lithosphere and gravity and aeromagnetic, I propose a the lithospheric structural framework model for the Chinese mainland and adjacent area, specially the COS.

利用国际最新的地球重力场模型(UTCSR GRACE/GFZ EIGEN-GRACE)和GTOPO 30数字高程模型，笔者首先计算了中国大陆不同球谐阶次大地水准面异常、岩石圈均衡剩余大地水准面异常和水平应力场分布，从岩石圈内多层次均衡角度进行了解释推断；其次，结合地表地质和其它综合地球物理资料，分区段对中央造山系及邻区分析与解释了岩石圈细结构；然后，通过东亚地区地震层析、大地水准面异常和卫星岩石圈磁场、全国重力与航空磁力对比分析，建立了中国大陆及其邻区岩石圈，特别是中央造山系的初步结构框架。

Secondly, under the guideline of earth system science, we put forward a theory of universal tectonics,initially build the theoreticl system based on studying the history of geotectonics and present level of earth science.

以地球系统科学为指导思想，在对大地构造学发展史和地球科学现状总结、分析和研究的基础上，提出了统一构造理论的新观点和理论基础，初步建立了理论体系框架。

So, despite the excitement of finding such primeval pieces of the earth, most scientists, including me, continued to accept the view that the climate of our young planet was Hadean .

因此，尽管找到这麽原始的地球残片是如此令人振奋，包括我在内的大部份科学家仍然继续采信地球年轻时的气候是超古元状态的观点。

Four billion years ago, asteroids and comets rained down on our planet with such ferocity that scientists have labeled the era the "Hadean "--literally, hell on Earth.

40亿年以前，小行星和彗星犹如雨点一般密集地砸在地球上，撞击极为猛烈，科学家们管这个时代叫做&冥古代&，顾名思义就是地球上的地狱时代。

The Earth's temperatures and seasons have become inalterably fixed in their present state and that the Earth cannot be hurled off into space or drawn into the sun.

地球的温度和季节不会变化，固定在它们应有的状态上，地球不能被掷出太空或吸到太阳里。
