In this study, unbalanced magnetron sputtering approach was used to prepare silicon oxycarbide (SiCO) ceramics in the form of thin film. The SiCO thin films were synthesised by reactive radio-frequency sputtering with a SiC target and oxygen gas. Nano-indentation and scratch test were used to study the mechanical properties of SiCO film at different substrate temperatures. An optimal temperature was proposed by analysing Young's modulus, surface roughness and adhesion strength.

To optimise the overall structural design of high-power LED and to effectively improve thermal dissipation, we analyse the thermal structure of high-power LED. Firstly, the thermal problems of high-power LED are described in detail. A complete thermal model is established based on finite element method. Secondly, numerical simulations on the theoretical analysis of LED system are made. The results show that there are three aspects in this part of the thermal resistance. The thermal dissipation of LED could be increased and then the LED junction temperature is also controlled within a certain range. Secondly, we investigate the factors which mainly influence heat dissipation. Meanwhile, we simulate the relationships between the temperature of LED chip and the height h of the radiator, the radius R of the radiator and the radius r of LED lamp posts, respectively. The results show clearly the effects of various factors on the temperature of LED chip. Meanwhile, without affecting the structures of the radiator and ED lamp posts, the optimal values of each single factor are found. The results reveal the thermal field mechanism of LED system, which is very helpful for design and manufacturing of LED assembly.

Semi-flowable self-consolidating concrete (SFSCC) was developed to address the issue of shape stability while possessing self-consolidation properties in pavement concrete. In an unrodded flow test using a standard slump cone, SFSCC has a flow diameter of 27.9-33.0 cm, slump of 15.2-20.3 cm and symmetric cone shape. The green strength of a freestanding fresh concrete cylinder in compression ranges from 1.3-2.5 kPa and the compaction factor should be ≥ 0.98. Applications to slip-form paving and sloping pavements are discussed based on two field constructions. The first is a bike path and the second is a street pavement. Both pavements were constructed without mechanical vibrators and were finished and cured in the same method as conventional concrete pavements.

In this paper, a function-based scheduling method combining with statistical analysis of historical runoff data and inflow data is proposed to calculate the initial water level of a reservoir under long-term optimal operation. Two-ary interpolation function and database searching are integrated in the solving process. An example is taken to demonstrate the feasibility and engineering practicability of this method. Initial water level obtained by this method establishes a foundation for making optimal scheduling plans.

Owing to the miniaturisation of solder bump connections, evaluations of the electromigration (EM) resistance of various lead-free solders have become increasingly important. In this paper, by utilising the sharp tip of a Cu trace, a simple method including easy sample preparation is proposed for EM resistance evaluation. The sample is prepared by surrounding the Cu traces with solder, and the EM resistance is evaluated by supplying a current between the traces. The current flows in the anode trace and flows from its sharp tip to the solder. The total volume of observed hillocks in the designated area near the tip of the Cu trace per unit time of current supply is used to determine the EM resistance. Rankings of the EM resistance in various solders under the same supplied current and sample temperature are theoretically proven to be invariable, regardless of their values. For testing materials, Sn-3.0Ag-0.5Cu and Sn-3.5Ag-0.5Cu-0.07Ni-0.01Ge solders (wt %) are used with 4N (99.99%) purity Sn as a reference. The usefulness of the present method is demonstrated by evaluating the EM resistance of these solders.
由于凸锡连接的小型化，各种无铅焊料的电迁移(EM)电阻的评估变得越来越重要。本文提出了一种利用铜痕量的尖端进行电磁电阻评估的简单方法。样品是通过用焊料包围Cu走线来制备的，并且通过在走线之间提供电流来评估EM电阻。电流在阳极迹线中流动，并从其尖端流向焊料。在单位时间的电流供应中，在铜走线尖端附近的指定区域观察到的丘的总体积用于确定电磁电阻。在相同的供电电流和样品温度下，无论其值如何，理论上证明各种焊料中的电磁电阻排名是不变的。测试材料采用Sn-3.0 ag -0.5 cu和Sn-3.5 ag -0.5 cu -0.07 ni -0.01 ge焊料(wt %)，以4N(99.99%)纯度Sn为基准。通过对这些焊料的电磁电阻进行评估，证明了本方法的有效性。

Selection of the tooth number is a challenging problem for engineers in designing harmonic drive, since the tooth number cannot be lower than a certain limit because of the gear strength. However, there is no equation to calculate the minimum tooth number for flexspline. In the present work a mathematical relation has been established to estimate the minimum tooth number for flexspline in harmonic drive based on the theory analyses in radial deformation, section stress, fatigue strength and safety factor on the flexspline, which changes the present situation that little research is done on the relationship between the strength of flexspline and its tooth number in open technical literature. The derived mathematical relation enables one to select a suitable tooth number for practical purposes in designing new harmonic drive; it could also be used to verify the fatigue strength in existing harmonic gear assembly.

This paper presents an empirical equation for the quantitative determination of the abrasion rate of concrete stilling basins by the impact of sediment in debris flow. The grain size in the experiments is not as big as the grain size of natural debris flow and the independent contribution of sediment impact on abrasion is not reported in previous studies. Therefore, the independent contribution of coarse-grain sediments impact on concrete slab investigated in this paper using two sets of experiments. Linear, power and exponential correlation equations were developed relating abrasion and cumulative potential energy per unit weight of concrete stilling basin using the first set of experiments. The equations were verified using a second set of experiments. The power equation was selected using the mean absolute relative error as the criterion. The study reveals that the reduced effect of water is less than 10% for dimensionless depth smaller than one.

In order to study compact strip production (CSP) hot strip mills vibration patterns and vibration source, field test was carried out at F2 (No. 3 Finisher), F3 (No. 4 Finisher) and F4 (No. 4 Finisher) mills which suffer from serious vibrations. The results show that the main driving system of F2 mill produces torsional resonance, which is caused by the gear housing and gear meshing impact. The F3 vibration form is roller horizontal vibration and vertical vibration of 50 Hz, which is caused by stand vertical vibration system first-order resonance derived from curved tooth spindles meshing shock. Roller horizontal vibration has collision, and the test curve top cutting disappears if the gap between the roller and the stand is eliminated. Roller vibration velocity is five times the allowable value of ISO 2372 requirements, and roller vertical vibration amplitude has affected the strip thickness quality target. Mill vibration characteristic parameters of nonlinear dynamics calculations show that the system possesses chaotic behaviours.

The aim of this paper is to provide a spanscale method to investigate and estimate the interfacial thermal conductivity (ITC) of ZnO/Al2O3; interface from the nanoscale to the microscale situation based on the non-equilibrium molecular dynamic (NEMD) method. Comparing the simulated with the experimental data, a fitting model of the ITC from the nanoscale to microscale is built to evaluate its changing rule. The results show that the ITC increased until bulking materials from the nanoscale to microscale. The scope of size effect area reduced to 30 nm from 600 nm and 330 nm comparing with each pure material. It means that the size effect of pure ZnO or Al2O3 materials can be avoided by compounding with Al2O3 or ZnO materials. It implies a potential method for electronic material design of packaging or micro/nano manufacturing.
