VELOPING“TWO-LINE”HYBRID RICE.THE POLLEN FERTILITY OF TGMS IS REGULATED BY THE TEMPERATURE OF ENVIRONMENT.THE POLLENS OF TGMS LINES ARE STERILE WHEN THE ENVI-RONMENT TEMPERATURE IS ABOVE A CRITICAL POINT,BUT FERTILE BELOW THIS POINT.SO FAR,A NUMBER OF T…     

A local positive feedback of the tropical Pacific ocean-atmosphere system on interdecadal timescales

SINCE THE 1990S, THE CLIMATIC VARIABILITY ON INTERDE- CADAL TIME SCALES BECAME THE FOCUS OF THE INTERNATIONAL CLIMATOLOGY RESEARCH MISSIONS[1―3]. ON TIME SCALES OF A DECADE OR MORE, THE OCEAN CIRCULATION PREDOMINATEDHEAT BALANCE AND HYDROLOGICAL CYCLE, S…     

Removing the impact of wind direction on remote sensing of sea surface salinity

Sea surface salinity (SSS) plays an important role in the sub-polar area, where intrusions with low salinity influence the deep thermohaline circulation and the meridional heal transport. SSS fields and their seasonal and inter-annual variability are thus…     

Seasonal variation of snow microbial community structure in the East Rongbuk glacier, Mt. Everest

Mt. Everest, the zenith of the world, plays an impor- tant role in the global climate change. During the lastdecade, some studies on glacier and snow have been undertaken in this region. The climate and environment changes in the past hundred years have b…     

Enzymatic hydrolysis of cellulose materials treated with ionic liquid [BMIM]Cl

1 Introduction Due to the enormous quantity and renewable char- acteristic of lignocellulosic materials, the efficient utilization of lignocellulose as food, livestock feed, and an energy resource has been receiving great attention. While the final sugar …     

幼虫的起源

长期以来，幼虫和成虫是由同一基因物种进化而来这一假设与许多生物学现象有着难以调和的矛盾。本书的作者提出了一个大胆的猜想——决定幼虫形态的相关基因可能是由不同种类动物交互移植而来，并通过举例论证了这一幼虫基因移植论的可行性。     

两个均值公式

引入了两个新的算术函数，并利用Perron公式给出了两个均值公式．结果表明，这两个不同的函数具有相同的均值分布．     

松树萎蔫病在安徽的侵染及其发生的气候分布研究

利用GIS技术对安徽省松树萎蔫病发生的空间分布和气候特征进行了分析．安徽省松树萎蔫病主要发生在年均温15～15．5℃，1月均温l～3℃，7月均温28-29℃，日平均气温大于10℃积温4900-5000℃。干燥度0．9～1．0，年降水量在l000-1400mm等降水线之间的广大区域内．     

多双曲复数中广义正则函数的Riemann-Hilbert边值问题

研究一类双曲复变函数的超定双曲型方程组的解（即多双曲复数的广义双曲正则函数），讨论它在一类柱形域上的Riemann—Hilbert边值问题，得到了其解的存在性和解的积分表达式．
