在与国际上同期海相地层锶同位素演化曲线对比的基础上，研究了晚白垩世海相碳酸盐锶同位素组成与主要地质事件的关系；在将本研究锶同位素数据融入到全球中新代海水锶同位素曲线的基础上，综合作出了中新生代海平面变化和锶同位素对照曲线，讨论了全球风化速率，造山事件，气候，海平面变化以及灾变性事件对中新生代海水锶同位素的控制作用；根据锶同位素地层学原理，本研究尝试将碳酸盐锶同位素组成用于海相地层定年上，利用已有的全球海水87Sr/86Sr值-年龄数据库和测试的藏南晚白垩海相碳酸盐的87Sr/86Sr值，确定了岗巴剖面Campanian/Santonian和Maastrichtian/Campanian阶界线，标定了广泛分布于白垩纪的厚壳蛤化石的年龄；本研究还将这些方法推广到了塔里木盆地井下奥陶纪地层的年龄标定，确定了中/上，中/下奥陶统界线，从锶同位素角度获得了古岩溶作用证据，显示锶同位素地层学在解决海相地层对比，年龄确定及在岩溶型油气储层研究中的潜在价值和良好应用前景。

In anatomy he studied the circulation of the blood and the action of the eye. He made discoveries in meteorology and geology, learned the effect of the moon on the tides, foreshadowed modern conceptions of continent formation, and surmised the nature of fossil shells. His scheme for the canalization of rivers still has practical value and he probably devised the hydrometer.

解剖学方面，他对血液循环和眼有着较深入的研究；气象学和地理学方面，它也表现出了卓越的才华：他认为海洋的潮汐形成与月球的运动密切相关；他提出的陆地形成观念与现代理论颇为相似；他还还对化石的形成和成分进行了有根据的猜测；他设计并亲自主持修建的运河灌溉工程时至今日仍然有实际的应用价值，而在此过程中他可能设计出了液体比重计的雏形。
