This paper analyzes in detail the basic principles of paleoclimate reconstruction and advances in research on climate changes recorded by multiple natural records which include stalagmite,peat and lake sediments in Southwest China during the Holocene.

Using conventional observational data, autographic records and satellite images, the authors studied a black storm caused by a dry squall line associated with a southern cold front at the northern foothills of Tianshan Mountains in Xinjiang on April 18, 1998.

Research and Application of the Auto-Record and Analysis System for Static Penetration Tests;

Introduced the development of crank press' movement system aided design software based on AutoCAD platform, expatiated upon a kind of self-learning expert knowledge system's construction and a kind of mechanism of auto-record and design report's auto-output in press design's calculations and checks.

For locating and analyzing the secure incidents of campus network, we need auto-logging and tracing all user s information.

In order to improve the campus network management efficiency, whenever a security event occurs, network operators can easily trace those users who abused the network or did illegal things, auto-logging campus network user information and relate things are required.
