对一类黑洞视界温度的研究

恒星演化到晚期的归宿是白矮星、中子星或黑洞，在形成黑洞时，如果黑洞质量分布不具有球对称性，月存在质量多极矩，这将导致黑洞视界面上出现高温现象，甚至在某些点出现异常温度的情况。     

Early Cambrian eodiscoid trilobites of the Yangtze Platform and their stratigraphic implications

Analysis of the taxonomy and stratigraphic distribution of the Early Cambrian eodiscoid trilobites of the Yangtze Platform indicates that species of Tsunyidiscus and Hupeidiscus can be used for biostratigraphic correlation. T. aclis occurs only in the lower Qiongzhusian, T. armatus occurs in the lower and middle Qiongzhusian, while T. niutitangensis and T. tingi occur mainly in the middle and upper Qiongzhusian, with only T. tingi extending upward into the lower Canglangpuian. H. orientalis first appears in the upper Qiongzhusian, reaching peak abundance in the lower Canglangpuian and becoming extinct above the Drepanuroides Zone. Biostratigraphic and lithostratigraphic correlations indicate that the limestone in the lower part of the Mingxinsi Formation, the Upper Member of Jiumenchong Formation, and the upper part of the Middle Member of the Huangbailing Formation, can be correlated with each other as Hupediscus, an index fossil of the lower Canglangpuian, is abundant in all these units. The lower part of the Niutitang and Jiumenchong formations in eastern Guizhou, which mainly represent Qiongzhusian strata, can be correlated with the Lower Member of the Huangbailing Formation. The basal part of the Niutitang Formation, which may be equivalent to the Upper Meishucunian Shiyantou Formation in eastern Yunnan, is very condensed. Well-preserved sponge faunas and non-mineralized fossils in the lower part of the Niutitang and Hetang formations are not older than Qiongzhusian in age.     

动态缓变Kerr-Newman时空中的粒子能级

在Kerr—Newman黑洞随时间缓慢变化的情况下，用时间变量表示其动态特征，通过解缓变的Kerr—Newman弯曲时空中的粒子运动方程，得出了缓变的Kerr—Newman时空中的粒子能级分布．并对此分布特征进行了研究。     

焊接孔长度对钢框架梁-柱刚性节点性能的影响

对焊接孔长度扩大的钢框架梁－柱刚性节点进行了空间非线性有限分析。分析结果表明，焊接孔长工的扩大显著地降低了梁－柱连接面处的对接焊缝和焊接孔切角端开裂以及翼缘脆性破坏的可能性，但过长的焊接孔也会导致梁侧向稳定的丧失。     

球对称动态黑洞Dirac场的量子热效应

用新的方法研究了球对称动态黑洞的热效应 .从Dirac四分量方程出发 ,经广义Tortoise坐标变换 ,直接导出黑洞的事件视界面方程及温度函数 ,并最终获得了Dirac粒子的热谱公式 .     

二维对称黑洞的研究

分别研究了用普通时间ｔ描述的二维静态时空和用爱丁顿时间ｖ描述的二维动态时空中的对称黑洞，得到了局部事件视界、黑洞温度和热辐射谱。进一步研究时间尺度变换的补偿效应发现，补偿场的纯规范势有２个分量，一个是黑洞温度，另一个是与温度的分化变化率有关的量。     

黑眼菊黄色素的提取工艺及稳定性研究

以黑眼菊舌状花为原料，在常温下用５０％丙酮水溶液浸泡４ｈ，经抽滤、浓缩，得到天然的黄色素胶质。该色素用乙醇－乙醚混合溶剂冲洗后可得到较纯的黄色素粉末。黑眼菊黄色素在中性条件下对光和热均稳定，ｐＨ＜７时呈浅黄色，ｐＨ＞７时为亮黄色。淀粉和ＮａＣｌ是使黑眼菊黄色素增色的介质；蔗糖是减色介质，但随蔗糖浓度增加，减色效应迅速减弱。黑眼菊黄色素水溶液ｐＨ＝７时，在３９０ｎｍ处有一吸收峰。
