Evident difference in thickness or depositional rate of loess appeared mainly since about 1.7 Ma B. P. The intensity of paleoclimatic information from the loess strata is inversely proportional to the resolution of paleoclimate over the plateau. 黄土地层的古气候信息强度与分辨率成反比,是全球信号和区域信号的叠加。黄土高原各地厚度或沉积速率的差别主要是1.7Ma以来形成的。

In this paper, we have given the propagator matrix of elastic wave in a lateral homogeneous medium for B. P. G. coordinate system. This propagator matrix may be represented with five matrix factors, among which four matrices are independent of the frequency. 本文在B、P、C坐标中给出了弹性波在横向均匀介质中的传播矩阵,并将其表示为五个形式简单的矩阵乘积,其中有四个矩阵是与频率无关的。
Manage cold climate risks period and the cold climate-event occuring at about 2320 a B. P. of the postglacial stage. 船舶冰级风险管理直面低温挑战和2320aB.P.左右的寒冷气候事件。
The analysis on geomorphology, lacustrine sedimentology, geochemistry and historical archeology proves that the lake level has been fluctuating since 10000 a B. P. During the early Holocene, the lake level began rising and reached its maximum height at 9000a B.P. 地貌、沉积物、地球化学分析及历史考古资料均证实,一万年以来湖面在总体收缩下降过程巾不断地波动着。全新世初期,湖面扩张抬升,9000aB.P。
Period and the cold climate-event occuring at about 2320 a B. P. of the postglacial stage. 和2320aB.P.左右的寒冷气候事件。
B. P. Simple analysis is made about this phenomenon in the paper. B.P气候最佳时期上海地区海平面表现出升中有降的现象,本文对这一短暂的海退现象作了简要的分析。
Warm-humid climate in Northwest China during the period of 40~ 30ka B. p.: geological records and origin 40~30kaB.P.中国西北地区暖湿气候的地质记录及成因探讨

Paleoclimatic variation can be obviously divided into five cold and five warm periods, two cold and one warm periods in 200,000-100,000 year B. p. 古气候变化是明显的,分为五个冷、暖期:20&10万年间有两个冷期和一个暖期;
To reconstruct the paleo-tidal current field in the Subei littoral plain area, a 2 D tidal numerical model has been developed, and the tides and tidal currents in the Bohai, Huanghai and Donghai Seas at 7000a B. P. and 3800a B. P. have been simulated. 建立了渤海、黄海、东海的二维潮流数学模型,对7000aB.P.与3800aB.P。
