Result: Operating time:(39 2±29 0) min, time of harvest donor heart:(7 3±4 8) min,warm ischemic time: (1 7±1 9) min, cold ischemic time:(126 0±27 6) min and the time of preparing donor heart:(26 4±14 4) min.
The newly-developed HVSC 800 extrusion casting machine can be used to manufacture qualified aluminum wheels for motorcycles provided that the technological parameters ,such as temperature field, operating time of cores,shooting speed and speed switching position are reasonably set.
The possibility to reduce the fault clearing time from0.1s to0.09s or0.08s on500kV transmission line is discussed by statistics analysis of the operating time of the protection device and the breaker. Analysis calculation and simulation test show that the stability limit can be improved by reducing the fault clearing time.
According to the operating time,the removal efficiency of the three nitrides could be divided into two phases,with the corresponding removals of NH~-_4-N,NO~-_3-N,TN being 93% and 99%,35% and 98%,and 71% and 98%,respectively,while the removal efficiency of TP was kept stable during the experiment.
This reactor safely Went to critical on November 2nd 1989,and reached its rated flux level of 1×10~(12)n/cm~2.s on November 10th 1989. Maxi-mum operating time under the condition when the neutron flux at inner irradiationsite is 1.1×10~(12)n/cm~2.s is 6.75 hours.
The relationships of COD and NH_3-N degradation rate with operating time were developed based on Eckenfelder and Monod model respectively. The maximum degradation rates of COD were 3.09 for CMBR with operating time=59d and 2.72 for SMBR with operating time =50d.
The new advance safety management pattern is put forward and real-time optimizing dispatch model is built up based on yield deviation minimization and electric shovel, truck waiting time and truck operating time minimization criterion, aimed at the deficiency of existing dispatch model and safety management pattern in this paper.
The specially organized reliability verification experiment is mentioned as follow: define the subsample number as 75, select the activation time and operating time to calculate the exact value of reliability of the thermal battery;
The article mainly adjusts and improves the front processing of the surface water ammonia nitrogen test so that it can be convieniently used to analyze large quantities of laboratory samples and save the operating time.
None of other nine patients, who underwent duct-to-jejunal end-to-side embedding pancreaticojejunostomy, was detected to have pancreatic leakage, and the operating time of these nine cases was less than other four cases.
The operating time of the MHD facility was 3.6 s, with the flow rate of combustion products of about 2 kg/s at a pressure in the plasma generator of pch ≈ 4 MPa.
It is demonstrated experimentally that the average operating time of a heat pipe increases abruptly with increasing number of turns.
The energy capacity of this generator is ～1 kJ, the total operating time is 25 μs, and the characteristic current rise time is ～2 μs.
This catalyst considerably improved the performance characteristics of the process (selectivity, specific activity, and operating time), as compared with available analogs.
