In this paper, the NU308 bearing rings were subjected to strengthen grinding treatment (SGT) at ambient temperature. And the running reliabilities of specimens that subjected to SGT and conventional treatment (CT) were respectively investigated by testing dynamic properties including the running temperature, vibrations, and surface burning. Moreover, the residual stress, microtopography, and microstructures on the cross-section were respectively tested with residual stress analyzer and field-emission scanning electron microscopy. The results showed that the running reliabilities of the specimen after SGT had been significantly improved with the reduction of running temperature, vibration, and surface burning. Further study showed that the specimen’s surface was filled with disordered micropores after SGT compared to the regular strip texture on the CT specimen’s surface, and the maximum residual compressive stress induced by SGT was about −900 MPa. Moreover, the thickness of the residual compressive stress layer was over 180 µm, while the thickness of severe plastic deformation layer was about 50 µm.

胶质瘤是中枢神经系统最常见的原发肿瘤,具有高度异质性。基因分型对胶质瘤的临床治疗方案的制订及预测预后具有重要意义。目前,研究较为成熟及广泛的基因分型有:异柠檬酸脱氢酶(isocitrate dehydrogenase, IDH)、1p/19q非编码缺失、O^(6)-甲基鸟嘌呤-DNA-甲基转移酶(O^(6)-methylguanine-DNA methyhransferase, MGMT)、端粒逆转录酶(telomerasereverse transcriptase,TERT)、表皮生长因子受体(epidermal growth factor receptor, EGFR)等。多模态MRI如扩散张量成像(diffusion tensor imaging, DTI)、神经突方向离散度与密度成像(neurite orienttation dispersion and density imaging, NODDI)、平均表观传播扩散子(mean apparent propagator, MAP)-MRI、酰胺质子转移(amide proton transfer, ATP)成像及2-羟基戊二酸MR波谱(2-hydroxyglutarate magnetic resonance spectroscopy, 2HG-MRS)等可以从多方面预测胶质瘤基因分型,从而指导进行下一步治疗。T2液体衰减反转恢复(T2-fluid attenuated inversion recovery, T2-FLAIR)不匹配征是IDH突变星形细胞瘤的高特异度,低敏感度的成像标志物,具有可观的临床应用潜能。本文就这几项MRI技术及T2-FLAIR不匹配征在胶质瘤基因分型方面的研究进展作一综述。

Acta Oceanologica Sinica 1988年第4期7卷 607-620页

The studied area is a shallow water area that belongs to the East China Sea continent shelf. The distribution of zooplankton biomass is higher inshore than offshore. The maximum abundance is in the inshore edge of the centre of upwelling, which is the superposed area of the salinity front and temperature front, due to the fact that the mixture of three different waters has brought about a concentration of nutrients. The herbivorous Euphausia, Copepoda and Tunicata are the major groups of the abundant area. Tunicata possess the possibility to compete against other kinds of herbivorous zooplankton. This means that there is negative correlation between the distribution of Tunicata and that of Copepoda and Euphausia. The positions of maximum areas of zooplankton biomass, phytoplankton individual and the concentration of phosphates and chlorophyll-a overlap one another. In the centre of upwelling, zooplankton can not adapt itself to the environment of lower temperature and less oxygen even with rich nutrient
