The optical interference intensity ROll technique, which enables measurements of filmthickness of magnitude below half of the wavelength of the incident light, is widely used in thestudy of thin film lubrication (TFl). However, the absorbing characteristics of the metallic compo-nents which are for generating suitable amount of reflectance to facilitate optimum inference im-ages has never been taken into consideration. This paper presents a theoretical analysis of theabsorbing characteristics. Results indicate that without acknowledging the absorbing effects, sig-nificant errors in film thickness measurements can be induced.

为了克服现有方法在表面粗糙度测量范围和抗震动等方面的不足，分析了最近发展起来的几种动态表面粗糙度测量方法的优缺点，提出采用被测表面激光反射图的暗区比来实现运动表面粗糙度的实时测量。该方法的测量范围可达３０倍跨度，即可测量的表面粗糙度为０．０５μｍ到１．６μｍ或０．４μｍ到１２．５μｍ。分析了试样的运动速度和初试平均光强对暗区比的影响，该方法的测量结果与Ｔｅｌｙｅｒ－ｓｏｆｔ表面形貌测量仪的测量结果很吻合。

The general friction and wear performance of an iron particulate suspension underboundary lubrication conditions are presented. The suspension is a mixture of 1-5 micrometerdiameter carbonyl iron particles with commercial hydraulic oil, which resembles typical compositionof magneto-rheological fluids. The investigation involves changing the particle concentration of thesuspension. The optimal concentration of the suspension from a tribological view point can be ob-served from the experimental results,which provides a reference to the design of the particle load-ing of magneto-rheological fluids.

Cells undergo metabolic reprogramming to adapt to changes in nutrient availability, cellular activity, and transitions in cell states. The balance between glycolysis and mitochondrial respiration is crucial for energy production, and metabolic reprogramming stipulates a shift in such balance to optimize both bioenergetic efficiency and anabolic requirements. Failure in switching bioenergetic dependence can lead to maladaptation and pathogenesis. While cellular degradation is known to recycle precursor molecules for anabolism, its potential role in regulating energy production remains less explored. The bioenergetic switch between glycolysis and mitochondrial respiration involves transcription factors and organelle homeostasis, which are both regulated by the cellular degradation pathways. A growing body of studies has demonstrated that both stem cells and differentiated cells exhibit bioenergetic switch upon perturbations of autophagic activity or endolysosomal processes. Here, we highlighted the current understanding of the interplay between degradation processes, specifically autophagy and endolysosomes, transcription factors, endolysosomal signaling, and mitochondrial homeostasis in shaping cellular bioenergetics. This review aims to summarize the relationship between degradation processes and bioenergetics, providing a foundation for future research to unveil deeper mechanistic insights into bioenergetic regulation.
