Based on investigations and studies of modern and ancient glaciers at the Tanggula Mountain pass, coupled with the GPS data and TL, 10B-26Al-21Ne and 14C dating data, Quaternary remnants of glaciation in the study area are discussed in detail. Two glacial epochs (i.e., the late Middle Pleistocene penultimate glacial epoch and the mid-late Late Pleistocene last glacial epoch) arid two Holocene glacial advances (i. e. the Neoglaciation and the Little Ice Age) have been intensively studied.

在对唐古拉山口现代冰川和古冰川考察研究的基础上，结合定位观测资料和TL、10B-26Al-21Ne及14C测年数据，对区内第四纪冰川遗迹进行了深入讨论，划分出二次冰期（即中更新世晚期的倒数第二次冰期、晚更新世中－晚期的末次冰期）和二次全新世冰进。

Our record shows a palaeoenvironmental transition from a warm 'greenhouse' world, during the late Palaeocene and early Eocene epochs, to a colder 'icehouse' world influenced by sea ice and icebergs from the middle Eocene epoch to the present.

我们的记录显示一幕由古老环境由处于旧世纪晚期和新世纪早期温暖的'温室'世界向由从新世纪中期到目前由海冰和冰山造成的比较寒冷的'冰室'世界转变。

Based on the analysis of tectonic deformation,extensional unconformity,sedimentary facies and paleogeographical rebuilding of southern Tibet,it is recognized that the extensional movement consists of active extension of Hercynian,Indo-Chinese and Early Yanshan epochs,and passive extension of the Himalayan epoch.

藏南特提斯域内伸展运动和伸展作用非常普遍，根据构造变形分析和伸展不整合、沉积岩相、古地理再造及岩相对比方法，对藏南海西期以来的伸展构造进行了较为系统的厘定，确定了海西期、印支期、早燕山期的主动伸展运动和晚燕山期和喜山期的被动伸展作用，并对这些运动特征进行了探讨。

The Mean Square Error of Neutral Network dropped to 0.001 after 242 training epochs.The maximum relative error of simulated value...

在均方差为0.001的条件下，网络于242次训练后收敛，模型训练的最大相对误差为2.58%，预测值的最大相对误差为10.08%，表明该模型具有良好的预测和仿真能力。

Four metallogenetic epochs occurred in different tectonic environments during the evolution of the Northern Qilian metallogenetic province through geological time .

北祁连金属成矿省在地质历史演化过程的不同构造环境内形成了四个主要金属成矿幕。

In the first epochs of Chinese history, the Negrito type peopled all the south of the country and even in the island of Hai-Nan, as we have attempted to prove in our study on the Negritos, on Black men of this island.

中国历史上的第一个朝代，矮小类型的黑人遍及整个国家南部，甚至于海南岛。

In order to achieve accurate solutions of ill-conditioned GPS equations with a few observational epochs, the ill-conditioned normal equations of GPS rapid positioning was transformed as a function optimization problem. Then genetic algorithm was used to calculate parameter solutions, which avoided the inversion of coefficient matrix of normal equations.

为准确解算仅有少数几个历元的GPS载波相位观测数据的病态定位方程，将GPS快速定位的病态法方程求解问题转化为一个函数优化问题，应用遗传算法求解病态方程，避免了法方程的求逆运算，从而可以得到参数的近似最优解。
