As one of the most important terminals in machining, cutting tools have been widely used for components manufacturing in aerospace and other industries. The quality of these components and processing efficiency are closely linked to the performance of cutting tools. Therefore, it is essential and critical to inspect the cutting tools and monitor the condition during the stage of manufacturing and machining. This review aims to discuss and summarize the key problems, methods,and techniques from the perspective of the tool geometric and the physical quantities measurement,including machine vision, physical sensors and data processing. It is worth mentioning that we focus on the topic of precision measurement methods and discuss universal solutions by identifying the common characteristics of the measured quantities. Eventually, the challenges and future trends for the development of in-depth research and practical applications are concluded. The research and application of precise measurement techniques for geometric and physical quantities will better promote the development of intelligent manufacturing.

陕北黄土高原地区生态环境脆弱,区内滑坡等地质灾害多发,随着极端降雨频发、人类工程活动剧烈等因素的影响,区内地质灾害发育特征及发育类型有了新的变化。在充分结合已有资料的基础上,以陕北榆林市榆阳区为例开展了地质灾害详细调查和分析。结果表明:区内的地质灾害主要有滑坡、崩塌和地面塌陷,并发育黄土崩塌-泥流灾害链和采动型塌-滑灾害链。滑坡可分为黄土滑坡、黄土-红层滑坡、黄土-基岩滑坡和岩质滑坡,其中黄土滑坡诱发因素主要有降雨、开挖和河流侧蚀等,不同诱发因素下滑坡成灾模式不尽相同。区内发育的崩塌包括黄土崩塌和岩质崩塌,黄土崩塌成灾模式包括滑移式和倾倒式,岩质崩塌成灾模式为崩落式。区内煤矿开采频繁导致地面塌陷,形成了地面裂缝、塌陷错台、塌陷槽和塌陷坑频发等现象。最后,分析了区域内新出现的黄土崩塌-泥流灾害链和采动型塌-滑灾害链的形成机理。研究成果可为黄土高原地区地质灾害防治规划和保障重大工程安全与长期服役提供一定的参考。

In coastal areas, excessive exploitation of groundwater causes seawater intrusion. In artificial recharge of aquifer remediation process, the replacement of saltwater and freshwater with each other causes colloid release, and permeability also decreases. In this paper, the aquifer samples containing minimal clay mineral(mainly illite) in Dagu River aquifer were used. Adopting horizontal column experiments, we studied the influences of seepage velocity and ionic strength on particle release, as well as the relationship between them. In the column experiments, the Critical Salt Concentration(CSC) of the Dagu River aquifer was determined as 0.05 mol L^(-1) approximately. This result was basically consistent with the DLVO theoretical calculation. For the constant seepage velocity, the salinity descending rate and partical release were slower, and the peak of particle concentration was lower. However, the total amount of released particles was almost constant at different salinity descending rate. For constant salinity descending rates, the peak of particle concentration decreased as seepage velocity increased, but the total amount of released particles rose up. The experiments also indicated the existence of a critical seepage velocity, which dropped with the decrease of salt concentration. When the concentration of Na Cl solution decreased from 0.17 mol L^(-1) to 0.06 mol L^(-1), the critical seepage velocity decreased from 3 cm min^(-1)to 2.5 cm min^(-1), which is consistent to the results predicted by DLVO theory.

Sea cucumber A postichopus japonicus stock enhancement by releasing hatchery-produced seeds is a management tool used to recover its population under natural environmental conditions. To assess the suitability of releasing sites, we examined the microbiota of the gut contents of A. japonicus from two populations(one in sandy-muddy seagrass beds and one in rocky intertidal reefs) and the microbiota in their surrounding sediments. The activities of digestive and immune-related enzymes in the A. japonicus were also examined. The results indicated that higher bacterial richness and Shannon diversity index were observed in all the seagrass-bed samples. There were significant differences in intestinal and sediment microorganisms between the two habitats, with a 2.87 times higher abundance of Firmicutes in the seagrass bed sediments than that in the reefs. Meanwhile, Bacteroidetes and Actinobacteria were significantly higher abundant in the gut content of A. japonicus from seagrass bed than those from the reefs. In addition, the seagrass-bed samples exhibited a relatively higher abundance of potential probiotics. Principal coordinates analysis and heatmap showed the bacterial communities were classifi ed into two groups corresponding to the two habitat types. Moreover, compared to A. japonicus obtained from rocky intertidal habitat, those obtained from the seagrass bed showed higher lysozyme, superoxide dismutase and protease activities. Our results suggest that bacterial communities present in seagrass beds might enhance the digestive function and immunity of A. japonicus. Therefore, compared with the rocky intertidal reef, seagrass bed seems to be more beneficial for the survival of A. japonicus.
