After the improved reliability engineering × X2 × × I and the radar, and its reliability improved reliability engineering than the one without a 31 - a × × 3 × × 4 radar Xiang higher. 2o hour increased 17% in the Philippines cliff; 50 hours increases the reliability of 44Ji00 hours increases the reliability of 1O. This is the long-term continuous operation of the radar has positive significance., \ Figure 1, the reliability curves in Figure 2. After twenty column D by sex workers, radar reliability, the average growth rate of m increased by 15. from Table 3 can be seen as appropriate, without reliability engineering,[link widoczny dla zalogowanych], the natural increase in the average growth rate of the public's radar for the 0316 to carry out the reliability of the radar work, the average growth rate of m = 0363. raise the growth rate is short time to improve the reliability of the primary means of radar. 3. circle can be seen from the curve, × × l radar and high reliability, which was the culmination of three years,[link widoczny dla zalogowanych], its hard work to obtain a growth rate of 0401,[link widoczny dla zalogowanych], is a high growth rate. Here's an example to x × 1 radar to explore the engineering measures to improve the reliability of growth. Third,[link widoczny dla zalogowanych], to ensure the reliability of radar growth can be ● engineering methods of pre-Si-1 and sub-fold in order to properly estimate × x1 radar level of reliability,[link widoczny dla zalogowanych], the reliability growth on an actual basis. We are in Nanjing, Wuhan and Rong are other places, the same type of radar and abroad reliability was a lot of research. some of the information shown in Table 4 . from the survey of the material point of view, the value of the various definitions in the MTBF, the verifier factually reflect the reliability of water almost. the reliability of the radar of large domestic water almost, M1BF validation of the value of roughly 30 to 100 small between the resistance (per device array London> 10000), and × × 1 radar failure rate of components, design, technological level and other major I choose District Council. _ to, but up to scratch with the \King barrier-free requirements (8O% confidence level in the Sui l brother under the very MI'BF = 30 hours) is a complete barrier possible. Majesty to the appraisal meeting in 1983, × × 1-32-0 mouth 0O0O00 reliable radar test failures with greater specificity. go 4 Radar Type l × 1 × 2 × 3 × 4: × 5 test time 1982j983198319, 831983l984l90319831I1MTBF31.6557. {788.537833765O (hours) ● ____ ● ● - ● _-_-__ --- ● _ ● ● - ● __。__--______-____---___________-。。_- ● ● -.. ● _-● - ● -----。____- ____-____________ ● _________________________________-____ ● ____ ● ______________,_ 198483.3 on the basis of the investigation should be car \detailed forecasts. reliability block diagram is as follows; various sub-systems _ Reliability Prediction Results Results: Name the failure rate.
