The evaluation technology for reliability of Nuclear grade instruments is one of the important methods to assure congenital excellence of the products, It can take precautions against calamity and it is powerful method to wholly check and evaluate the readability and security of the products from various phases including design, fabrication, assembly, testing, routine test and special environment test, reliability test, operating life simulation test, etc.
Six axils locomotive roll-rig is an important equipment for new-model locomotive and routine test in electric locomotive works. The testing system for the roll-rig not only requires large numbers of data acquisition channels, high measurement precision and sampling frequency but also can be configured flexibly.
This system has been successfully applied to the routine examination of refrigerator in HongTai Electrical Company of Shandong, a project supported by the International Green Environmentalist organization—non-Freon refrigerator assembly line.
The differences between the up to date UIC standards for locomotive diesel engines and the relevant present standards in Chinese railway industry were briefly analyzed. The comparisons were made in terms of authentication methods, authentication tests, routine tests and acceptance conditions.
A method to evaluate equipments reliability by using every type of test information,such as performance test,functional demonstration and other routine tests,has been introduced. The method can make full use of test data abtained from various tests,it can,therefore,reduce the cost and time of special reliability test,and it may lay an indispensable technical foundation for equipment reliability evaluation and validation at present.
Working electrolyte is selected by orthonormal experiment and assembled 160V/1μF capacitors which make all experiments, including 2000 hours 160V、85℃ and 125℃ high temperature reliability experiments to examine all kinds of capacitor electrical performances.
Depending on above theory, experiments were performed to select elementaryformula, than 160V/47μF tantalum capacitors were assembled with it. Theirperformances were measured at room temperature, high and low temperature and highfrequency after aging, and than 2000h high temperature burden examination and otherentirely duty exams were carried out. The performances turned out to be very good,and satisfied the requirement of the project.
Thus, 31P-MRS should not be a routine test for MM, but may be an important research tool.
The paper describes a routine test for screening toxicity and growth inhibition of purified proteins in artificial diets onAcyrthosiphon pisum (Harris).
It makes it possible to monitor adequate anticoagulation, but PMN-elastase results must be proven during routine use before recommendation as a routine test.
This paper describes experiments performed with 30 subjects which indicate that the rate of strength build-up in repeated exertions may provide objective criteria to judge whether or not a subject exerts full muscular strength in a routine test.
The determining of urine- and serum-lysozyme may be regarded as specific to the kidney and can be recommended as a routine test after a kidney transplant.
Important information on the presence of asynchrony can be obtained already during a standard routine examination with conventional techniques (2D, M-mode and Doppler).
They appeared mainly in the motor nuclei of the brainstem and spinal cord on a routine examination.
The influence of artificial blood contamination on the quantitative values obtained in the routine examination of the CSF was investigated.
The laboratory examinations included blood clot culture, phage typing, Widal test, haemoglobin, leucocyte count, transaminases, serum bilirubin, and routine examination and culture of stool and urine.
The changes of clinical symptoms and signs, and laboratory indices such as erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), antistreptolysin O (ASO), routine examination of blood and urine, liver and kidney function, etc.
in household appliances was partly burned in routine experiment.
eccentricity, during a routine experiment was estimated to be less than 1.0?mm and hence did not influence the measured torque output under our experimental conditions.
A coefficient of variation of the IP better than 2% was found in a routine experiment (10 mg sample, 150 C, 60 ml/min air flow rate, aluminum pan) for typical oils which had an IP range of 25-31 min.
To address this issue we report here a modified version of the routine experiment and a processing scheme that provides a 1D-STD homodecoupled spectrum (i.e.
This efficient transformation procedure led to an average of four independent transformed lines per gram of cocultivated embryogenic tissue and up to 50 transformed lines can be obtained in a routine experiment.
Although a fraction of FBCs identified in our study was similar to those described in other European countries and in the United States, the percentages of genetic mutations seen on routine tests were relatively low.
Electrophysiological routine tests of distal nerves were usually normal except in nerve segments with conduction block.
In all patients with pure or predominantly motor syndromes and normal findings in electrophysiological routine tests of distal nerve segments, there should be proximal conduction block studies to avoid overlooking a treatable disorder such as MMN.
Routine tests of the anorectum for gonorrhoea are essential in cases of women at risk, and for most homosexual men since over 80 per cent of these men will have had passive anorectal intercourse.
The second part of the study is based upon results from routine tests for CA andM.
The Morle-fringe scale by resistance chain introduced in this article is a method of grating Morle-fringe in hinge electronic scale. Its circuit has-been successfully applied to the angle-measuring system of two precision instruments developed in the Institute.
According to the theorem of complex harmonic drive, this paper extendsits meaning and presents a new system of closed power current (that is asystem of drive ratio i=∞). Moreover, this paper researches and analysesthe characteristics and advantages of the system used as test-bed in assemblyand conventional tests, and explains with practical examples. To comprehendand apply it conveniently, at first, this paper also in troduces the conceptof closed power and its applications in gear drive test-bed.
TYSY-5 Piezoelectric gyro is a novel miniaturized solid transducer with the physical size of 36×64x16mm3, weight of~100g, power supply of 0.5W (for the type of non-constant temperature),output gradient of~ 18mV/°/s,preparation time of 10 minutes,and atmospheric temperature of -40℃ to +50℃. Other routine tests are demonstrated to meet the needs of aeronautics. Particularly, this transducer is available for solid-state angular rate sensors used in telemeterring of air-to-air missiles.
