查询词典 elevated temperature

The new GV preparation method we developed allowed the best visualization of chromatin distribution after Hoechst or CMA3 staining. Our results showed that GV chromatin configurations are different among different species, and thus, while chromatin condensed into a ring around the nucleolus in porcine and bovine oocytes, no such a ring was observed in caprine oocytes; Porcine oocytes were synchronized at GV1, goat oocytes at GV3n and bovine oocytes at GVf configurations before GVBD occurred, indicating that these configurations are progressive towards final maturation rather than atresia; Changes of chromatin configurations were associated with gene activity of transcription; GV chromatin configurations were affected by the environmental changes such as serum starvation and elevated temperature.

应用该技术对猪、山羊和牛不同大小、不同健康程度卵泡及体内和体外成熟过程中卵母细胞染色质构型的变化发现：1）不同动物卵母细胞染色质构型不同；猪和牛卵母细胞染色质围绕核仁凝集形成环，但山羊卵则没有此环。2）卵母细胞在GVBD之前都同步在某一染色质构型；猪同步在GV1，山羊GV3n，牛GVf，说明这些染色质构型代表着进行性变化。3）染色质构型的变化反映基因转录活动的变化。4）染色质构型受环境变化的影响。

Firstly, achieving a new low and high cycle noninterfering loading, the high frequency induction local heating, the control of high cycle vibration frequency and amplitude, and the crack propagation real-time detection, an experimental system of L-HCCF at elevated temperature is established. Secondly, under two vibration frequency (50Hz and 100Hz), the contrast experiment of light and serious corrosion disc slots is done. It is found that the experimental L-HCCF life of serious corrosion disc is less than that of light's, but its dispersion is larger, and the experimental failure is identical with the service's.

首先，进行大量试验工作，提出了高低周疲劳载荷的新型加载方案，并解决了高频感应局部加温、振动调频及裂纹实时监测等多个技术难点，建立了涡轮盘全尺寸高温复合疲劳试验系统；验证试验做到了故障再现；接着进行了两种频比（振频50HZ与100HZ）的轻、重腐蚀盘的对比试验；由对榫槽第一齿进行裂纹实时跟踪，得出了枞树型榫槽的复合疲劳裂纹扩展特点规律；对榫齿断口进行的金相分析表明：裂纹首先由第一齿开始，断口系复合疲劳；试验结果显示：重腐蚀盘试验寿命较轻腐蚀盘有显著的下降，而且分散性较大。
