Result of calibration shows that piezoelectric characteristic of PVDF(5 mm×5 mm) is linear if the pressure is lower than 150 MPa. Piezoelectric coefficient of PVDF is about 20 pC/N after the calibrated data fitting.
Based on the hardware and software of the electronic control system and the calibration and demarcation for the diesel engine, the control tactic and the best control data are studied for diesel engine.
Computer system is made up with RS485 communication network, which burdens the tasks of data sampling and data dealing and data communication. Furthermore, module demarcation, module channel configuration, module communication network and so on. The PLC system is centered on programmable logic controller, Which can perform the functions of controlling negative and positive wheeling of electromagnetism valve, start and stop of motors, flux data sampling, communication with data display terminals, controlling transducer, PID control to heater and parameters self-adjustment process.
In order to solve the demarcation of the relative parameters in the measuring process of engine properties,the method ot a intelligent real-time demarcation has been developed,which overcomes the non-linear problem in the measurement system,automatically removes the system error and improve measurement precision.
It is necessary to match the Electronic Control System with the engine and to optimize and calibrate the control parameters in order to meet the China Emission Standard and get better power and economic performance.
In the 4th chapter the questions of NOX emissions are detailed investigated and the creation mechanism is analyzed particularly considering the influence of temperatures. And the demarcate experiment of temperatures field is introduced in this chapter.
The temperature stability of photoinduced fiber refractive index gratings at different demarcation energies was calculated on the basis of the data obtained.
The results of studies of genetic regulation of the early leaf morphogenesis, demarcation of the future primordium and transition of cells to determination, have been reviewed.
In addition, it enables one to clarify conditions under which the morphologies form, as well as to explain the effect of target temperature on the demarcation line between the morphologies.
If an amputation is necessary, it should happen 6-8 weeks later after complete demarcation of the necrosis, in the special case of sepsis immediately.
An unequivocal demarcation of frequency and pressure effects and of inotropic mechanisms as just as impossible, because, with the exception of VmaxDP, all parameters react quantitatively and qualitatively in an equal manner.
Test results indicate that the accuracy and repeatability are high, and the method can be used to calibrate geometric errors on the plane of CNC machine tools after backlash errors have been well compensated.
The neutrino source developed on the basis of 37Ar was used to calibrate the SAGE gallium-germanium solar neutrino telescope.
A technique using the reaction of chlorine atoms with C2H6 is developed to calibrate the sensitivity of the apparatus to chlorine atoms.
These isotopes are required to calibrate automatic installations used for determining noble gases at international stations of radionuclide monitoring.
The accumulated data were used to construct and calibrate the spectra of solar flares and compact active regions with a spectral resolution of 0.04 ?.
More recently, these strategies have been replaced by efforts to protect boundaries and demarcate its Blavatskian roots.
Graphical exhibits clearly demarcate the optimum use of cables under changes in cost-factors.
By crosschecking the results it was possible to demarcate a focus of vestibular projections in the ventro-caudal part of the thalamus, situated between the centre median, the ventro-basal group and the caudal segment of the ventro-lateral nucleus.
Considering the shape of the latency histograms in this and earlier studies, as well as other data, it appears unlikely that these very short transition latencies demarcate the distinction between predictive and fully visually-guided saccades.
A basic feature of patchiness shown by the spinules is of ontogenetic interest: arrangement of these patches appears to demarcate individual epidermal cells.
In this paper the design of an identical-velocity sampler to collect flyash and soot in flue gases is described., The sampler is compact in construction and self-aligning. The velocity in the sampling tube can be accurately maintained in identical with that in the main stream to make the sample representative. It employs the hot filtration process within the furnace to improve the accuracy of its measurement. Besides, it can be used to measure the velocity of the main stream while taking sample.

In this paper the design of an identical-velocity sampler to collect flyash and soot in flue gases is described., The sampler is compact in construction and self-aligning. The velocity in the sampling tube can be accurately maintained in identical with that in the main stream to make the sample representative. It employs the hot filtration process within the furnace to improve the accuracy of its measurement. Besides, it can be used to measure the velocity of the main stream while taking sample. Calibration in cold conditions and testing in hot working conditions proved that this sampler is convenient in use and accurate in measurement.
The 18GJ radial-flow turbo charger is developed to meet the needs of the new 6200 diesel engine. It has undergone 1000 hours' endurance test under standard condition together with the diesel engine. This paper gives an all-round description of the basic views in the design of the structure of the 18GJ radial-flow turbo charger, and presents parameters and information concerning the design.
