A low temperature test for both designs was conducted according to the Standard ASHRAE 93-1986 (RA 91).
Then a series of environmental and reliability tests have been proceeded with online or offline monitoring of its working performance, including high & low temperature test, vibration test, shock test and tensile test, strictly according to National standard and Oil & Gas Industry Standard.
The time averaged temperature error was reduced from 0.37 °C to 0.09 °C in the high temperature test, and that of the low temperature test was reduced from 0.42 °C to 0.18 °C.
In this paper, to extend the application of ENDB specimen for wider geometries and environmental conditions, a large number of mode I fracture toughness tests are conducted on HMA mixtures containing different air void percentages and at three low temperature test conditions (0, −12 and −24 °C).
In order to realize the simulation of the low temperature testing environment, a cooling chamber was used.
For low temperature testing, the specimens were submerged in methanol in a Kinetics Multi Cool MC480A1 chiller for a minimum of 5 min.
In addition, the total number of petal plus stamen was less in RhAG-silenced flowers than in TRV controls, while it was not influenced in the low temperature test.
The data suggest that the oxygen solubility at the relatively low temperatures tested (<95 °C) controls the preference of the cathodic reaction, i.e. oxygen reduction versus nitrate reduction.
The present QCM-D results confirm and detail the great enhancement effect of calcium in whey fouling, even at the low temperatures tested, increasing the fouling rates by more than hundred times at free calcium concentrations of 40 80 mg/L.
