each case, the specimens were compressed to half their original height and the load-displacement data was recorded.
Plates will separate along the bonding face at reduction ratios of 2%, 4%, 6%, 8% and 10%, as shown in Fig.5 b).
Though it is noted that dissimilar metals and alloys can be joined by hot rolling at a large reduction ratio, the reduction ratios in the experiments were too small to create a strong bonding between the Al alloy plate and the Mg alloy plate.
Fig. 5 Separation of laminated composites at different reduction ratio: a) 1% and b) 2%.
The maximum strain at different positions increases with the reduction ration, λ.

The simplified Bishop method uses GeoSLP1 software to calculate, and the strength reduction finite element method uses ABAQUS 6.10 software to calculate.
When using strength reduction finite element method, elastic modulus of soil is valued as 200MPa, Poisson's ratio is valued as 0.3.
The calculated stability factors using formula (1), formula (2), simplified Bishop method and strength reduction finite element method were recorded as F1, F2, F3 and F4.
(2) Simplified Bishop method and strength reduction finite element method can be checked each other because stability factors obtained by the two methods.
The former is easy to grasp for the first-line technical staff as its principle is intuitively clear, the latter can obtain the potential sliding surface, the stress, strain and displacement data of slope automatically but the calculation process is complex

Since it has mainly been applied focusing on civil engineering structure, however, research data on mechanical area structure is very limited.
In addition, objective data on the superiority and economic value of technology can be obtained through independent LCA analytical technology.
In the case of Intercity Bus in Canada, it presented 4.5% and 10% cost reduction effects respectively for 9% vehicle frame weight reduction and 20% weight reduction for fuel costs in operating costs as a result of vehicle frame weight reduction using composite from 9% up to 20%.
As for ecological cost savings costs according to respective weight reduction rates, they were found to be 9.8 million won (9% weight reduction), 21.8 million won (20% weight reduction), 15 million won (14% weight reduction) and 18 million won (16.5% weight reduction) during 9 years.
This study considered transportation vehicle frame of composite structure being produced domestically, and it presented basic data on partial cost research method on LCA from the initial production to operation and disposal of mechanical and aircraft structure applied with composite.

Cathode research in
DMFC technology is mainly focused on developing more selective and methanol-tolerant catalysts
for oxygen reduction.
These catalysts were electrochemically tested for their activity towards methanol oxidation and oxygen reduction in a half cell arrangement.
Completing reduction of the precursor, nitrogen gas was streamed in order to remove hydrogen.
Several standard composites were prepared by same method from general precursor for comparison of data.
As shown in Fig.2, these data indicate that PtTm-C is less active toward O2 reduction than Pt-C.

The cell voltage, electrolyte temperature, and CR of these cells were reduced with the days of operation and agreed with the data published elsewhere [6, 10] and with Q-350 cells [21].
This result agrees with data published elsewhere [35], where reducing the cell instability from 0.072 to 0.063 µΩ led to an increase in the current efficiency by 2 % and a decrease in the energy consumption by 0.23 kW/kg Al [35].
Many thanks to the head of R & D and staff of production research for their continuous encouragement and supplying with some valuable data during this study.
And I had full access to all study data, take full responsibility for the accuracy of the data analysis, and have authority over manuscript preparation and decisions to submit the manuscript for publication.

Implementing the security monitoring and control can timely provide the critical data and information on the security control of the artificial island and also monitor the data acquisition and analysis, which offer a reference value of the information engineering technology on the artificial island construction[3].
The safety monitoring system should include sensing systems, data acquisition as well as analysis systems and the monitoring center.
The sensing system includes a program of the perception of component selection and layout of sensor networks in the structure; data acquisition and analysis systems are composed of a powerful computer system, which can realize different physical signal acquisition and preprocessing.
To ensure reliable monitoring data, the feasible reference control method must be considered and ensure that the sensing instrument has sufficient accuracy and life, measures can be taken: (1) sea Island security monitoring has long cycles and poor environment.
So data acquisition with high precision, better durability optical fiber grating sensor equipment and components are recommended.(2)deep horizontal displacement monitoring, inclinometer tube depth than the potential of the deepest sliding failure surface below and left a certain margin to the bottom of the hole, the pore water pressure monitoring, early to establish a different depth points with different depth of the static pressure correction curve.(3) taking a scientific and reasonable data acquisition and processing method, sifting a large number of monitoring data then receiving the relative real monitoring data and comparing with the theoretical analysis.

The performance of the system was verified through experiments where it acted as a component of a vibration reduction system.
The damper and the generator are the key components of a developed vibration reduction system with energy harvesting.
Description of the system Underlying the prototype of the conditioning system are the research data summarised in [1].
The microcontroller block, incorporating a PIC16LF1827 chip, generates steering signals to analogue relays: q (AS_C), qGB (AS_GB) and qBC (AS_BC) and transmits the measurement data to the computer via a RS232 interface.
Summary The paper briefly outlines the operating principles of the system for conditioning signals from an electromagnetic generator that are used to power supply an MR damper and summarises the laboratory test data.

From 2001 to 2010, there was no significant difference of CH4 emissions per unit area between the cities, all CH4 emissions reduction was mainly due to a reduction of rice growing area.
After searching and screening, get in line with the requirements of the research on data integration [3-11], which contained the CH4 emission data of 51, distributed in 7 test points.
Experimental treatment of CH4 emission from rice data including: water management style, applied or not applied straw, the test set of different water management measures.
In this study, the rice average CH4 emissions and per unit area of the foundation data were calculated for the study area CH4 fluxes.
In 2001-2010, there are rice planting area and area reduction ratio in south Jiangsu area ( Tab. 1 ).
