The Research of Maximum Power Point Tracking Technology in Photovoltaic Grid-connected System
Solar power is a new green power. It is regarded as clean, pollution-free, and inexhaustible. Photovoltaic conversion is an effective way to use solar power. Because the price of photovoltaic cell is expensive and conversion efficiency is low presently, the Maximum Power Point Tracking is absolutely necessary, in order to decrease system cost and increase [...]
The Research of Coordination Mechanism in Port Transportation Organizing Based on Cooperative Game
The national port enterprises have met unprecedented historical opportunities and challenges as the production center transfer to Asia caused by economic globalization and national economy developing in a high speed. The production abilities of port are made by multiple processes which including tasks of receiving and dispatching goods, warehousing and storage, loading and unloading, Ship [...]
The Study on Supply-Demand Balance for Throughput Capacity of the Container Ports in China
This paper mainly studied the future balance between the demand on throughput and the supply of handling capacity of China’s container ports. Being affected by financial crisis, economy in the world has not fully recovered from the shock, and a direct result is the slowdown in China’s import and export trade. In addition, China’s economic [...]
Preparation and Property Research of TiO2-based Photocatalyst and CuBi2O4 Thin Films
With the development of industry and economy of human society, environmental and energy problems have been becoming more and more serious. Since Fujishima and Honda have reported the evolution of oxygen and hydrogen from a TiO2 electrode under the irradiation of light in 1972, photocatalysis was regarded as one of the most effective and economical [...]
Research on the Influence of the Ultrasonic Reflection Device on the Flow Characteristic of the Ultrasonic Flow Meter
At present, the government is vigorously promoting energy conservation and emission reduction, which requires high precision tools to measure the resources and energy. The ultrasonic flow meter as a high precision fluid measurement tool will play a major role in this activity. But the technological level of domestic flow meter is not high enough, and [...]
Research on Technique of Construction Surveying of Single Tower Cable-stayed Bridge
Cable-stayed bridge has become the fastest growing and the most competitive bridge type in modern bridge construction for its excellent spanning ability, rational stress system and novel structure. The cable tower is the primary load-carrying member and an important component of cable-stayed bridge. Almost all of the mobile load and permanent load of cable-stayed bridge [...]
Research on Aerodynamic Characteristic of High Speed Bus
Nowadays, as the technologies of bus develop and the level of manufacture improves, the aerodynamic characteristic of buses are drew attention more and more. The forces and moments which bus experiences influence the fuel economy and steer stability. The researches of cutting down the drag are more and more important along with the crisis of [...]
Research on Allocation of Water Resources in Eastern Urban of Jinan and Spring Level Simulation
Jinan is the the political, economic and cultural center of Shandong Province with a big population, per capita water resources of which accounts for only one-tenth of the national per capita water resources. Urban population is more dense. Jinan is famous for its springs. However, due to groundwater over-exploitation, the spring has begun drying up [...]
Study of Quality Control and Evaluation Methods of Earth Dam Reinforcement
There are a large number of reservoirs to be reinforced. As the government intensifying the reinforcement work, many dangerous reservoirs will be strengthened. As the reservoir seepage reinforcement of the complexity and hidden nature, controlling the strengthening quality and inspecting the reinforcement effect is particularly important. Some of the most commonly used control and detection [...]
Vibration Characteristic and Wind-induced Vibration Investigations of Energy-saving Sandwich Composite Panels Used in Steel Residential House
In order to implement the national energy-saving environmental protection policies, as well as to respond to the call of building a low carbon society, energy-saving of buildings gradually becomes a hot topic. In this context, sandwich composite panels for steel residential house came into being and developed quickly. As a new kind of exterior cladding [...]
