英译中!Calculations to utilize values appropriate to material p

这句英语该怎么读懂?
我分不清主谓宾,请帮下忙吧：
Reviewed calculations titled “Adjusting screw redesign evaluation”,sizes 1/4,1/2,3/4 &
1,and 1 1/2 & 2 inches and consisting of materials SA216 WCC Steel & SA-193-B7,
SA351 CF3M SST & SA-193-B7,and A126-B Cast Iron & SAE Grade 5,all dated

It is important to give detailed calculations of the IS index for a series of examples covering a range of process industry stages:from research to producing a new product until decommissioning of a plant after its useful life is over.A quick way to obtain an approximate value of the index is needed since,for several relative comparisons,this may be enough.（其中IS是本质安全）

since the derivative is involved in the calculations,the
initial estimation of the term dω/dt may be very much in error.

I will make the taxes calculations and keep you posted about it.

After performing relevant calculations,the results indicate
that the resonance displacement mean square root
behavior on the surface of packing,which is caused by
the fl uid,has a biggest value in the middle of the packing,
and it becomes bigger with an increasing number of
layers of packing,and the biggest value of displacement
mean square root behavior is 1.383×10-8 m while the corresponding
surface stress is 7.637 kPa.

文章如下,是关于混凝土的.
Thermodynamic calculations were performed to investigate at which sulphate ion concentration hardened concrete can be damaged by the
formation of thaumasite.It is indicated that thaumasite can be formed from C–S–H phases and portlandite at very low sulphate concentrations in
an aggressive solution.Higher sulphate ion concentrations are required in the absence of portlandite.Still higher sulphate ion concentrations are
needed if C–S–H phases with a low calcium/silicon ratio are consumed.Therefore,it is suggested that the formation of thaumasite at low and
moderate sulphate concentrations in the attacking solution can be avoided by lowering the calcium/silicon ratio in the C–S–H phases.This can be
achieved by the addition of pozzolanic and latently hydraulic admixtures.During the reaction of these materials,portlandite is consumed and the
calcium/silicon ratio of the C–S–H phases is lowered.

请问这篇GRE阅读是什么意思
Calculations of the density of alloys based on
Bernal-type models of the alloy‘s metal component
agreed fairly well with the experimentall y determined
Line values from measurements on alloys
consisting of a
5 noble metal together with ametalloid,such as alloys of
palladium and silicon,or alloys consisting of iron,
phosphorus,and carbon,although small discrepancies
remained.One difference between real alloys and the
hard spheres used in Bernal models is that the
10 components of an alloy have different sizes,so that
models based on two sizes of spheres are more
appropriate for a binary alloy,for
example.The smaller
metalloid atoms of the alloy might fit into holes in the
dense,random-packed structure of the larger metal
atoms.
