Based upon the effect of land-sea interaction on the paleomonsoon variation and the time series of climatic proxy-indicators, the historical Asian monsoon variation over the last 130,000 and 18,000 years has been reconstructed with an emphasis on the basic characteristics of summer monsoon circulation. The monsoon-climatic cycles and associated model of environmental development over the central and eastern China are proposed and the mechanism of paleomonsoon variation of China preliminarily discussed. The variation of East Asian monsoon circulation should be regarded as a regional result of both solar-radiation changes and the global glacial-interglacial cycles. The episodic uplifting of the Qinghai-Xizang Plateau since the late Miocene has to a large extent controlled the forming and evolution of the paleomonsoon circulation of China.

本文详细地介绍了我们研制成功的LISP-130解释系统。本系统以LISP1.5文本为主要依据,并吸取了其他LISP系统的特点,构成94个系统函数,以这94个函数为基础,可以方便地定义出各种新函数。 LISP语言是人工智能、模式识别及其他求解非数值问题的基本语言。国外越来越多的计算机开始配备LISP类型的语言,成为系统软件的基本组成部分。 随着国内计算机应用领域的不断扩大,非数值应用的比重越来越大,迫切需要适合于非数值计算的语言。同时考虑到国产DJS-130机已被广泛使用,为此研制了适用于DJS-130小型机的LISP独立解释系统。本系统于1980年11月鉴定通过。
