A new spatial database based on region and object data model is designed. The database could dispose many data sources. It provides application interfaces and has some flexibility.

Along with the development of PLD device and EDA technology, more and more electrical engineers use FPGA to implement FIR filter, as it not only meet the real-time requirement, but also has some flexibility.

Thread is new and operating-system-level concept in Win32, and it does not exist in 16-bits Windows environment. Thread brings some flexibility to the development of application.

To adapt CAPP to the variety and update of the products of the manufacturing enterprises whose processes are quite different each other, a new type CAPP system,the QKCAPP system with some flexibility and good process succession, which can link the server database and the user database and attain the purpose of high speed process design, is suggested in the paper.

Thus, a new training header length is suggested that would allow vendors some flexibility in choosing the structure that best suites their product.

These covers are available in a number of different sizes, allowing some flexibility when covering each section of the network.

These generic models may be appropriate for many contexts where the costs of changing states are partially irrecoverable, yet where management has some flexibility to alter scale, quality and pricing of assets and services.

The varying nature of the composition of multimedia presentations provides some flexibility for scheduling their retrieval.

Some deviation of experimental data from the theoretical curves probably is an indication of some flexibility and/or fractal nature of the molecular clusters.

The fluid dynamics of the hydraulic setworks is of influence on the accuracy. The dynamic vibration of hydraulic system is characteristic of instantaneous velocity, pressure and its oscillation. The piston of a rack cylinder creatsinertia load, being subjected to the difference of pressure at the entrance and exit of the cylinder. On the basis of Newton's second Law, a motion differential equation has been put forward, by which a formula to calculating instantaneous velocity has been obtained. The cylindrical...

The fluid dynamics of the hydraulic setworks is of influence on the accuracy. The dynamic vibration of hydraulic system is characteristic of instantaneous velocity, pressure and its oscillation. The piston of a rack cylinder creatsinertia load, being subjected to the difference of pressure at the entrance and exit of the cylinder. On the basis of Newton's second Law, a motion differential equation has been put forward, by which a formula to calculating instantaneous velocity has been obtained. The cylindrical liquid in cavities on both sides of piston of the rack cylinder considered as two springs possessing some flexibility and a cylindrical liquid springmass vibration modeled,the vibration equation can be got after which is solved and formula calculating instantaneous pressure will be obtained and analysing have proved that the maximum instantaneous velocity, pressure and its oscillation can be reduced by selecting an optimum piston area and fluid velocity, which would improve the operational performances of setworks and setting accuracy.

Some flexibility of the method of undetermined Largrange multiplier is studied in this paper. (1) The non-uniqueness of the expression of undetermined Lagrange multiplier. (2) The introduction of undetermined Lagrange multiplier in variational expression of original functional. (3) The derivation of generalized variational principles with preconditions by the use of the Lagrange multiplier method. (4) An exceptional cose arising, frem using the method of undetermined Lagrange multiplier.

This paper introduces the control structure of some flexibility manufacture system and scheme of MAP network interface. Performance of lower layers is analyzed by queuing theory model, and the time-restrictive condition that protocol software must meet is abtained.
