A Research on Exchange Rate Risk Management of China’s Shipbuilding Enterprises
In recent years, China has achieved a leap in the development of shipbuilding industry. As the “going out” strategy had been further implemented, the number of exports of ships increased rapidly. Now, China has already become one of the world’s major shipbuilding centers. Shipbuilding industry has always been an export-oriented industry with high degree of [...]
Research on the Modulation Method Application in the Angular Sensor System
Angle measurement is an important component of the geometrical dimensional measurement technologies. It plays an important role in the modern quality control system. With the development of the precision machining and ultra-high-speed machining, the study on the method of small-angle measurement with high-precision and high-resolution in this field has become an important element. Small-angle measurement [...]
RGB Chlorophyll Instrument’s Optimized and Its Measuring Model Regressed
Portable chlorophyll instrument is used to measure a relative chlorophyll content, which have advantages of real-time, rapid, and non-destructive. Using this instrument measures chlorophyll content of plant leaf, such as to guide nitrogenous fertilizer application, so that study plant’s physiological features, tapping the production potential and variety resources according as scientific basis. This paper presents [...]
Design of Micro-Electronic Speckle Interferometry System
Electronic speckle pattern interferometry (ESPI) technology has optical measurement merits on high accuracy, non-contact, whole field measurement, it also has the electronic technology’s advantages such as high velocity, the automation, the operation easily and so on, and it can measure the distortion of optics scored surface, recent years, engineers and researchers from various countries are [...]
Study on the Key Technology of Measuring Large High-Temperature Forging with Optical-Contact Target
The dimension of large open-die forging with high temperature is a dispensable indicator in the production. It is directly related to the quality of the product and post-processing. By summing up both domestic and international measuring methods, a new one is proposed: optical-contact target flexible CMMs. In this system, the most important part which will [...]
The Design of Reflective-light Screen Precision Velocity Measuring System
For the supersonic flight of bullets and artillery shells of these objects, to study its speed measurement methods and technology for getting the muzzle velocity and flight path of a bullet or a shell in the shooting range test, is of great significance.The dual-light screen velocity measuring system researched by our laboratory has passed the [...]
Design and Analysis of the Two Color Mould of the Auto Pipeline Bracket
The auto pipeline bracket is made in of nylon for a long time at home. Repeatelly rubbing hard nylon bracket and soft nylon will result in abrasion of outside pipeline, And it is dangerous. At FAW-Volkswagen Automotive Company Ltd., the pipeline bracket of autos is made of two materials in the future. It can reduce [...]
A Research on the Risk Management of CNG filling Stations in Jinan and Emergency Response System
At present, CNG is an ideal substitute energy for automobiles. The technology of its application has entered a mature stage. CNG plays an integral part in domestic optimal adjustment of energy structure as well as in national energy strategy. As a new type of motor fuel, the application of CNG is widely promoted. Under the [...]
The Research and Discussion of the Design Elements Related with Motorcycle Safety
With more than twenty years of rapid development, China has become the largest producer of motorcycles. In the international market competition, some domestic motorcycle companies are gradually aware that the products which only focus on basic functions can not compete with those produced by well-known overseas companies, and that they must pay much attention to [...]
The Research of the Flexible Berthing System for the Oil Transmition on New LVDA Oil-field LIAODONG Bay
Considering the possibly bigger economic and timing cost for long distance pipeline constructions, quite often it may also be necessary to accommodate importing tankers coming from the base port or neighbor fields for oil/gas transmissions. The tanker mooring/berthing terminals are usually working as an important portion of the production systems of offshore oil/gas fields in [...]
