查询词典 plotting scale

From 500℃ to 550℃, the oxide scale presents a relatively compact morphology, the oxidational wear is the principal wear mechanism and the wear rate is very slow at 500℃ owing to the anti-friction effect of the oxide scale.

本文研究了5CrNiMo在400℃、500℃、550℃及600℃温度下的滑动磨损行为，利用扫描电镜，波谱仪及X射线衍射仪对磨损面形貌及成分进行了分析，结果表明：5CrNiMo钢磨损机制随温度的变化而变化，400℃时表现为疲劳剥落和磨粒磨损，500℃至550℃时表现为氧化磨损，600℃时主要是粘着磨损。

Based on this idea, the author has chosen two typical loess sections of Luochuan, and Xifeng for this study, collected the successive loess columns; To probe the conditional experiments of BeO sample preparation and measurement, and improve the existing method; On the basis of the technology improvement, the author has finished 402 samples' BeO preparation and AMS measurement; Also at the same time, to separate quartz from samples at 1 cm interval for both Luochuan and Xifeng sections systematically, to carry out measurements of quartz grain-size, SUS, grey scale, carbonate content and bulk sample density; By using the grain size model, the author has set up the chronological framework for both Luochuan, and Xifeng sections and the time sequence of millennial scale abrupt climate events recorded in loess strata, and reconstructed the East Asian monsoon history over 130ka by using multi proxies; Finally, to discuss the possible mechanisms of palaeoclimatic changes tentatively.

详细地球科学的发展离不开高精度和高分辨率的研究。运用长寿命核素如〓Be作为环境过程的示踪，已成为不可替代的有效工具。本论文选择洛川、西峰两个典型的黄土剖面，连续采集柱状样；探索了BeO样品制备、测量的条件实验，改进了原有的方法，完成了402个BeO样品的制备和AMS测量；同时还系统地分离洛川、西峰剖面高分辨率（1cm）黄土、古土壤样品中的碎屑石英，测量了碎屑石英粒度，以及全样的磁化率、灰度、碳酸盐含量和容重等古气候代用指标；采用粒度年代模式建立了洛川剖面和西峰剖面的年代标尺，建立了黄土地层记录的千年尺度的气候突变事件的时间序列，多指标重建了最近130ka东亚季风变迁史；初步讨论了古气候变迁的可能机制。

It had been found that when the relative molecular weight changed, the properties changed also. When the relative molecular weight of PESA is in the range 800 to 1000, the scale inhibitions are best. When the relative molecular weight of PESA is lower than 700 or higher than 1000, the scale inhibition becomes worse.
