In today's demand-driven economy, enterprises should pay more attention to customer needs, and use the market information to impenetrate all processes to make the products/service satisfy the customer needs more efficiently and effectively. In order to satisfy the needs of customer and improve the performance of organization, managers(often in partnership with consultants) have resorted to a variety...
As Camphora essential oil has excellent antibacterial properties, studying camphora oil could provide a theoretical basis for the discovery and development a new high-performance and low toxicity of antimicrobial agents. According to the results of this study, the essential oil of Camphor wood has natural anti-bacterial function, it is bacteria suppression on Escherichia coli, Staphylococcus aureus,...
An optimized gate-enhanced (GE) power UMOSFET with split gate (SGE-UMOS) is proposed. This device shows the reduction in specific on-state resistance (Rsp) at a breakdown voltage of 119 V as compared to the gradient oxide-bypassed (GOB) UMOS and GE-UMOS devices, which is due to the higher N-type concentration in the drift region. In addition, the split-gate floating structure in SGE-UMOS also reduces...
The behavior of formaldehyde release from plywood was similar to the creep behavior of material and the liquid. So the behavior of the formaldehyde emission from plywood was modeled by the rheological theory. And the Maxwell model, Delvin model and Burger model were used to fit the creep behavior which the formaldehyde released from plywood. The results show that the derived creeping model is fit...
There is the theology of the plywood formaldehyde-emission which is similar to the solid and the liquid. The mature theory of rheological is applied to study on the mechanism of the plywood formaldehyde-emission in this paper, and the loose models of the plywood formaldehyde emission are created. The formularies FM = F0e-0.1429t and P = P0/k(1-e-0.1429t) can be received and used to describe the influence...
The chemical composition of fresh Cinnamomum camphora were separated and analyzed by GC/MS. It was determined that 17 relative content by area normalization. 17 compounds of the extractives were identified. The main and abundant constituents were Eucalyptol, 3-Cyclohexen-1-ol,bicyclo[3.1.0]hexane, 4-methylene, beta.-Pinene, 3-Cyclohexen-1-ol, 4-methyl-1-(1-methylethyl), 1,3-Cyclohexadiene, 1-methyl-4-(1-methylethyl),...
The increasing demand for paper in Asia is being met by the use of Eucalyptus urophylla to a large extent. However, some pulp mills may be forcedly closed because the Eucalyptus urophylla chips contain extractives severely enough to pollute the water. In this paper, the chemical components in the benzene/ethanol extractives of Eucalyptus urophylla chips were isolated and identified by Py-GC/MS to...
Much waste wood causing pollution and energy waste was produced in the processing of Pinus massoniana wood. However, hemicellulose extracted from Pinus massoniana waste can be transformed into bioenergy by means of pyrolysis, gasification, liquefaction, etc. Therefore, effects of deresination technology on extracting hemicellulose from Pinus massioniana were investigated by orthogonal and the whole...
Both stabilizer and couple-agent can affect the melt index of composite materials. Moreover, the different varieties of same stabilizer and couple-agents also results in the difference of melt index of composite materials. The result of melt index test showed that, under the test condition of load 21.6 kg and temperature 190 degC, the melt index of bamboo-plastic composite which was added hot stabilizer...
Bambusa blumeana is the one of the most impotent bamboo species in South China. In order to exploit the high- grade resource utilization as bioenergy, determination of chemical components in Bambusa blumeana was made by using Py-GC/MS. Results indicated that the main components of Bambusa blumeana by Py-GC/MS analysis were carbon dioxide (30.99%), acetic acid (13.67%), tuaminoheptane (9.81%), diazene,...
In this study, isotropic wet etching technology has been developed to achieve the pyramidal needle structures on one side polished chemical pure titanium substrate. Different etchants, mask materials and substrate materials combinations were investigated respectively for process optimization. A steady etch rate in excess of 2 mum/min has been achieved with sputtered Ni mask. For the first time, bulk...
