求高手翻译（微电子专业英语）！
in the following,the band structures of various important and prototype semiconductors are discussed. the band below the fundamental energy gap is called the valence band. The band above it the conduction band .The bandgap is the energy separation between the highest valence-band state and the lowest conduction-band state . The maximum of the valence band is for most semiconductors at the T point.
1.Silicon
for silicon,an elemental semiconductors,(Fig.3.2)the minimum of the conduction band is located chose to the X point at 0.85(^/a) in the dirction .Thus,it is not at the same point in k-space as the top of the valence band . such a band structure is called indirect . since there are six equivalent directions,there are six equivalent minima of the conduction band.
2.GaAs
GaAs (Fig.3.3) is a compound semiconductor with a direct bandgap since the top of the valence band and the bottom of the conduction band are at the same position in k-space (at the T point).The next highest (local) minimum in the conduction band is close to the L point.

1 For aluminium alloy structures,the insulation is to be such that the temperature of the
structural core does not rise more than 200 above the ambient temperature at any time during
the applicable fire exposure.
2 For composite structures,the insulation is to be such that the temperature of the
laminate does not rise more than the minimum temperature of deflection under load of the
resin at any time during the applecable fire exposure .The temperature of deflection under
load is to be determined in accordance with a recognised international standard.
3 Insulation need only be applied on the side that is exposed to the greatest fire
risk,ieinside the engine room,a division between two such spaces should however be insulated
on both sides unless it is a steel division.
4 Special attention is to be given to the fixing of fire door frames in bulkheads
constructed of materials other than steel.Measures are to be taken to ersure that the
temperature of the fixings when exposed to fire does not exceed the temperature at which the
bulkhead itself looses sterngth.
2.1 A:Machinery spaces of category "A",are to be enclosed by "A-13"Class divisions.
B:For Short Range Yachts,machinery spaces of category "A",are to be enclosed by "B-15"
Class divisions.
2.2 Openings in 'A'and'B' Class divisions are to be provided with permanently attached
means of closing that are to be at least as effective for resisting fires as the divisions
inwhich they are fitted.Generally,windows should not be fitted in machinery space
boundaries.
2.3 Where 'A'Class divisions are penetrated for the passage of electric
cables,pipes,trunks,ducts,etc,or for girders,beams or other structural members,arrangements
are to be made to ensure that the fire resistance is not impaired.
2.4 Where 'B'Class divisions are penetrated for the passage of electric
cables,pipes,trunks,ducts,etc,or for the fitting of ventilation terminals,lighting fixtures
and similar devices,arrangements are to be made to ensure that the fire resistance is not
impaired.
2.5 Where the structure or 'A'Class divisions are required to be insulated,it is to be
ensured that the heat from a fire is not transmitted through the intersections and terminal
points of the divisions or penetrations to uninsulated boundaries.Where the insulation
installed does not achieve this,arrangements are to be made to prevent this heat
transmission by insulating the horizontal and vertical boundaries or penetrations for a
distance of 450mm(this may be reduced to 380mm on steel divisions only).
