Exhaust stroke
Pumping stroke
第7题:
higher boiling temperature for a given pressure than does a pure refrigerant
lower boiling temperature for a given pressure than does a pure refrigerant
boiling pressure equal to that of a pure refrigerant at a given pressure
boiling point will not be affected by entrained oil

last part of the intake stroke only
early part of the injection stroke only
early part of the power stroke
第9题:

a two-stroke engine works without exhaust operation
a two-stroke engine works without compression stroke
a two-stroke engine works without expansion stroke
a two-stroke engine works without suction operation
第11题:

B.a pure individual matter
C.a pure religious affair
D.more important to the parents
第14题:
专门用于测试前庭功能是()
第15题:
感受器的换能作用(sensory transduction)
第16题:
在感觉统合障碍的评估中,以下哪一个是由理论直接产生的评估量表:()
第17题:
the same indicated horsepower as a four-stroke/cycle engine
twice the indicated horsepower as a four-stroke/cycle engine
one half indicated horsepower as a four-stroke/cycle engine
one power stroke for every two crankshaft revolutions
第18题:
The medium speed 4-stroke trunk piston engine
The low speed 2-stroke crosshead engine
The medium speed 2-stroke crosshead engine
The low speed 4-stroke trunk piston engine
第19题:
most critical in a four-stroke cycle diesel engine
most critical in a two-stroke/cycle diesel engine
most critical in a four-stroke/cycle diesel engine if it is turbocharged
of equal importance in a two-stroke/cycle diesel engine as in a four-stroke/cycle diesel engine
第20题:
In a two-stroke/cycle engine, the rings run hotter, requiring the end gap to be greater
Some provision must be made in a two-stroke/cycle engine to keep the rings from binding in the ports
No gap is required to exist between the ends of the ring when cold in a two-stroke/cycle engine, but a small gap is required in a four-stoke/cycle engine
The gaps should be staggered on either side of a piston in a two-stroke/cycle engine, while staggering is not necessary in a four-stroke/cycle engine
第21题:
The direction of pressure on the journal in four-stroke engine is continuously
positive feed lubricators are installed on all bearings of four-stroke engine, whereas as a splash feed system is used on tow-stroke engine
four-stroke engines usually utilize a heavier grade of oil than tow-stroke engines
Low-stroke engines usually consume less lube oil than four-stroke engines
第22题:
a single, long-stroke, slow-speed, turbocharged, two-stroke diesel engine
a single, long-stroke, medium-speed, turbocharged, four-stroke diesel engine
two medium-speed, turbocharged, four-stroke diesel engines
a variable-speed AC generator
第23题:
two crankshaft revolutions in a two-stroke/cycle engine
two power strokes in a two-stroke/cycle engine
one power stroke in a two-stroke/cycle engine
two piston strokes in a two-stroke/cycle engine
