4.Experimental procedures
The fatigue gear tests were performed at a rotational speed of 745 rpm and applied torques of 220,147 and
73Nm.Two tests were undertaken at each torque to ensure repeatability.At regular intervals (ranging from
15 to 55 h depending on the applied torque levels),visual inspection of gear surface damage was undertaken,
oil sump temperatures were measured and oil samples were drawn for SOA (see Tables 1 and 2).Continuous AE rms values from the bearing casing and pinion gear were calculated in real-time by the analogue-to-digital converter (ADC) controlling software.This software employed a hardware accelerator to
perform calculations in real-time for a programmable time interval set by the user,10 ms in this instance and a
sampling interval of 90 ms was employed.Anti-aliasing filters were also employed prior to the ADC.Raw
vibration waveforms,sampled at 8192 Hz,were recorded for a period of 1 s at intervals of 30 min.Vibration
rms values were calculated over the recorded duration (1 s).
During the inspection interval,gear teeth surfaces on both the pinion and gear were visually inspected for
pitting or other abnormalities such as scoring and scuffing.The largest pitted area on any single tooth was
recorded.The authors set the failure,or test termination,criterion at 50% pitted area of the gear tooth surface
area.The visual inspections were performed by two separate inspectors independently and repeated for
consistency.This inspection error was determined to be 75% of pitted area.
The spectrometer used for SOA is an Atomic Emission type,namely inductively coupled plasma (ICP).The
analysis was performed by subjecting the oil sample to high-voltage plasma which energises the atomic
structure of the metallic elements,causing emission of light.The emitted light is subsequently focused into the
optical path of the spectrometer and separated by wavelength,converted to electrical energy and measured.
The intensity of the emitted light for any element is proportional to the concentration of wear metal suspended
in the lubricating fluid.The ICP used for determining levels of Fe elements in the lubricating fluid had an
accuracy of 73% at an average precision of 95% confidence level.

But many people fail to see the difference between fatigue—physucal tiredness——and sleepiness.

during sleep,the fatigue (疲劳) of the body disappears and recuperation ( 恢复) begins.the tired mind gathers new energy.once awake,the memory improves,and annoyance and problems are seen in a better perspective.
some adults require little sleep; others need eight to ten hours in every twenty-four.infants sleep sixteen to eighteen hours daily and,as they grow older,the amount gradually diminishes.young students may need twelve hours; university students may need ten.a worker with a physically demanding job may also need ten,whereas an executive worker under great pressure may manage on six to eight.many famous people are reputed to have required little sleep.napoleon,thomas edison and charles darwin apparently averaged only four to six hours a night.
whatever your individual need,you can be sure that by the age of thirty you will have slept for a total of more than twelve years.by that age you will also have developed a sleep routine:a favorite hour,a favorite bed,a favorite position,and a formula you need to follow in order to rest comfortably.investigators have tried to find out how long a person can go without sleep.several people have reached more than 115 hours nearly five days,whereas animals kept awake for from five to eight days have died of exhaustion.the limit for human beings is probably about a week.

studied microstructure,hardness,and thermal fatigue beha-
vior of H21 steel with several treatment morphologies (strength-
ening spots,stripes and network) processed by laser surface
remelting and reported that amongst all the three laser-treated
morphologies,strengthening network led to the best thermal
fatigue resistance.Another study [17] reported effects of strength-
ening stripes on the surface of the medium carbon steel and
showed that the specimen with 2-mm-spacing striation had the
highest resistance to thermal fatigue of all.Meanwhile,aforemen-
tioned geometric characteristics of units beneath the treated
surface should be considered as a significant factor influencing
the surface property.On the other hand,the cross-sectional
morphology and mechanical properties of units are both depen-
dent on laser processing parameters.Due to it,it is necessary to
investigate the relationship between the characteristics of biomi-
metic units(size,cross-sectional morphology,and mechanical
property) and processing parameters.
Note that in pulsed laser surface remelting(LSR),a series of
overlapping points make up the scanning track [18].Laser pulse
energy,duration,and scanning speed all place important effects.
In addition to the processing parameters such as pulse energy,
pulse width,frequency and scanning speed,overlapping ratio is
another significant factor in pulsed LSR.

2.2　Corrosion fatigue analysis
The corrosion environment in the vacuum distillation
tower can be regarded as a kind of solution with a mass
fraction of 0.5 mg KOH/g.After conducting calculations
regarding the solution with a mass fraction of 0.5 mg
KOH/g at a temperature of 310 ℃ and the solution with a
mass fraction of 50 mg H2SO4/g at a temperature of 25 ℃,
the Fe element has two chemical reaction rate values,
which are equal to each other approximately.As a result,
we can use the corrosion fatigue curve of Fe element in
the solution having a mass fraction of 50 mg H2SO4/g at a
temperature of 25 ℃ to predict the life range of packing
model.
Both the physical and chemical nature of 316 L stainless
steel and 19Cr12Ni stainless steel is similar.Therefore,if
we cannot get the corrosion fatigue curve of the former,
we can use the corrosion fatigue curve of the latter to analyze
the life range of packing model as an approximation.
Having known the character of corrosion fatigue curve of
19Cr12Ni stainless steel[11],which has a life range of 107
and 5×107 under a stress loading of 100 MPa and 80 MPa,
respectively,we then get the description of corrosion fatigue
curve of packing material expressed as a function
approximately.
