During electrochemical micromachining (EMM) , materials are removed in the form of ions based on the anodic dissolution mechanism, so it should be a promising technique for micromachining . A new kind of experimental setup of EMM was developed successfully, which is in fact a multifunctional machine tool, and micro-electrode tool can also be fabricated on the same machine tool. The developed experimental setup for EMM consists of feed unit, micro electrode fabrication unit, ultra-short pulse power supply, short circuit detection of machining current and so on. The experiments on micro electrochemical milling (micro EC milling) of typical micro-structure samples by the micro electrode tool rotating like micro milling cutter were carried out. The new feed strategy of micro EC milling was adopted. The comparative process experiments were carried out to explore the machining laws to meet the requirements for micromachining. At optimized parametric combinations, the micro triangle and the micro beam with width of about 50μm were milled on the stainless plate 304 by micro EC milling.

Based on the topography of micro WEDM surface, lubricant retention, bearing capability, and sealing performance were evaluated by using the surface bearing index, lubricant retention index of core area, and lubricant retention index of valley bottom respectively. The results show that the micro WEDM surface with the characteristic of isotropy texture is beneficial to store lubricating oil, and the lubricant retention property is superior to that of the traditional machining surface.

This paper evaluated the equipment’s dependability by the way of analytical method, and built the model of it. Combined the equipment’s historical data of use and detection with the current condition, it predicted the mission reliability of units by the way of fuzzy predictive. Then the equipment was departed into the part which is repairable and the part which could not. After all of this, the dependability of the two parts was evaluated. In the last, an example was showed.

Materials with infrared low emissivity have attracted great attention due to their increasingly important application in both military stealthy and thermal control. Hence, this work describes a facile, green method based on cotton fibers to fabricate hierarchically structured ZnO fibers and nanorod by simply immersion and calcination process. And infrared emissivity value of samples was also investigated. The cotton fiber adsorbed Zn2+ could be converted into ZnO nanorod by controlling reaction temperature and solution pH. The XRD pattern revealed the highly crystalline nature of the samples. In order to enhance the surface optical properties, the surfaces of biomorphic ZnO were modified by bovine serum albumin (BSA). The low infrared emissivity values were obtained in BSA modified samples, indicating that the surface properties of materials may play an important role in infrared emissivity control.

Electrochemical machining (ECM) is an anodic dissolution process of metal as anode ion by ion, and micro-ECM is a promising micromachining method at micro to meso-scale. Thus, a micro-ECM setup was developed to fabricate micro parts and explore the feasibility of micro-ECM at micro to meso-scale, including the design of high-frequency micro-energy pulse power supply. By using the detection unit of machining state and optical encoder, a closed loop control system for micro-ECM was developed. Under low concentration of passivating electrolyte, low machining voltage, micro rotating electrode and high-frequency short-pulse current, the machining gap can be reduced to about 10μm. The influence factors of the additives and the rotation of micro electrode on micro ECM were analysed by experiments. A micro-hole about 30μm in diameter was drilled by the rotating micro electrode.

A new technique for evaluating a microcalorimeter is presented in this paper. Its measurement principle is to change a thermistor mounts mismatch status by changing the reference resistance of its power meter bridge, measure a microcalorimeter in different mismatch status so that effective efficiency of the thermistor mount measured by the microcalorimeter can be used as the transfer value. This technique will shorten the measurement time and simplify the assembling procedure, while not reducing the evaluation accuracy. Its measurement principle and a experimental result are reported in this paper.

Microwave power standard adopts calorimetry techniques to calibrate the effective efficiency of the thermistor mount. Correction factor is the key of calibration thermistor mount.The microwave power standard mainly adopted short-circuited mode to determine the correction factor so far, but it must consider the effects of microwave power absorbed by short plate to thermopile, so the method that how to get the power dissipated in the short plate is the key to calculating correction factor and its uncertainty. This paper presents a new method based on electromagnetic field theory to consider the short-circuit dissipation power. A detailed analysis of its superiority over the traditional method is shown. It reduces the uncertainty of the correction factor reasonably, in other words, reduces the uncertainty of the microwave power standard.

As the development of economy, the utilization of tourism resources is like a raging fire. But in the process of development and use, ecological environment protection problems become a problem that we must face and solve .Through case and gambling research methods, this paper analyzes the ecological environment protection problems in Shangluo Jinsixia Tourism Development Zone in the process of tourism business, and puts forward suggestions and countermeasures according to the existing problems. Through careful analysis, this paper finds that local governments, the enterprise and the villagers have some interest conflicts and contradictions, and the conflicts between them will continue in the future. How to coordinate the interest conflicts between them, and how to lay a good foundation for the protection of the ecological environment become an important issue that we have to face and solve. This paper holds that the key to the problems is to strengthen the government's macroeconomic control, to supervise the tourist enterprises, and to cultivate the ecological and environmental protection consciousness between tourism enterprises and local villagers.
