Three main methods with lacustrine carbonates have been used to reconstruct the lake water palaeo-temperature at present. First, the technique of isotopic geological thermometer, since being put forward to reconstruct sea-water paleo-temperature, was subsequently introduced into lacustrine carbonate sediments for constructing lake-water based upon the function relationship between lake-water temperature and the oxygen isotopic compositions of lacustrine carbonate and lake-water. Second, paleo-temperature of the lake-water can be reconstructed by determining Mg/Ca values of the lacustrine ostracode shells. And third, paleo-temperature of the lake-water can be reconstructed based upon the statistic model between the oxygen isotopic composition of lacustrine carbonate and the Lake-water temperature by testing the modem hydrogeological parameters and some relevant isotopic data of the lake basin.

目前利用湖泊碳酸盐对湖泊古水温进行重建主要有三种方式，一是运用同位素地质温度计原理，利用水温与湖泊碳酸盐氧同位素值和湖水氧同位素值三者之间的函数关系，对湖泊古水温做定量研究；二是通过测定介壳[Mg(上标 2+)]/[Ca(上标 2+)]进而重建古水温；三是通过测定湖泊流域范围内现代水文气象参数及一些相关的同位素资料直接建立起湖泊自生碳酸盐氧同位素值与温度间的统计模型。

For the former one, data obtained from testing cases of overcutting and squeezing were used for numerical simulation calibration and comparison.

It utilized factor analysis and regression analysis ofthe multi-statistics to make the quantitative analysis on a great deal of core proxies in the North Indian Ocean and Indonesian Archipelago areas, and acquiredthe exact conversion relations of paleoceanic environment parameters (sea surface temperatureand salinity) and proxies. Then it made the change curve which can show the changes of paleo-ceanic environment parameters (sea surface temperature and salinity) which followed the changesof depth and provided the contrast between paleoceanic environment parameters of different coreson the landscape orientation. This paper supplied a more scientific and exact method for resumingthe paleoceanic environment on paleoceanography research.

本文阐述了以古海洋学数据库系统数据为基础的古海洋学多元统计分析模型，利用多元统计学中的因子分析和回归分析技术对北印度洋以及印尼多岛海地区大量岩芯的替代指标做定量分析，求出古环境参数与替代指标的精确转换关系，从而做出各岩芯处古环境参数随深度的变化曲线，提供不同岩芯在横向上的古环境参数对比，为古海洋学研究中恢复古环境提供了一种更科学更精确的方法。

成年健康Wista雄性大鼠62只，制作放射性直肠炎动物模型，直肠组织做病理检查，并用免疫组化方法比较肿瘤坏死因子-α的表达。

Recent studies, based on mathematical modelling, suggest that these drugs could be used prophylactically near the start of a pandemic to reduce the risk that a fully transmissible virus will emerge or at least to delay its international spread, thus gaining time to augment vaccine supplies.

最近的数学模型研究表明在临近大流行开始用这些药物做预防可降低具有人传人的病毒形成的风险，或至少可以推迟病毒的国际蔓延，从而为疫苗开发和扩大生产赢得宝贵时间。

Shannon's model can be modified to make practical provably secure cryptosystems possible.

假定敌手拥有无限的时间、设备和资金，对敌手的计算能力不做任何限制，那么即使敌手能在很短的时间内将所有的密钥都遍历一遍的话，基于信息理论安全模型的密码系统也不会被攻破。

This paper uses a physical model to check the reliability of the numerical modeling proposed by Chen. As an example, this paper deals with a horizontal well pumpage underneath a river bed, or a vertical well adjacent to the bank of the river. We use the numerical method of Chen to simulate the groundwater flow pattern of the physical model.
