Commodity Recommendation System of E-Commerce Based on Classification Users

英语翻译
Fluid mechanics deals with the flow of fluids.It has been conducted
both mathematically and experimentally.Prantl posited
that there is a thin layer near the surface of the body due to frictional
effects in a viscous fluid and the rest of the flow can be considered
inviscid.The idea led to a rational way of simplifying the
equations of motion in the different regions of the flow field
[1,2].Recent efforts have concentrated on turbulent flow.Many
predictions about initiation and the subsequent history of instability
growth are based on the application of buoyancy-drag models.
These predictions often illustrate general features,the details of
which are usually traced in numerical simulations.The buoyancy-
drag models provide representations of the early time instability
growth and material penetration phases in direct comparison
with the experimental evidence in their more refined and carefully
applied versions.Transport equations describing the evolution of
both spatial and temporal scales are required to achieve accurate
descriptions of turbulent transport [3,4].At the present time,there
exists no unified turbulent model.While numerous techniques
have been proposed for identifying organization in fluid motion,
they are typically statistical rather than physical and do not necessarily
provide desirable properties.
The aim of this paper is to propose a new concept,wave surface
of boundary layer.It is the interface between the main flow and the
boundary layer.It is generated by a tiny density difference whichresults from velocity difference between the main flow and the
boundary layer in the flow.When fluid moves,wave elements will
be generated on the surface of the boundary layer.The size of a
wave element is so small that it is impossible to conduct experiments
to observe it directly.We designed a series of ‘‘enlarged
size” experiments to show the oscillatory behaviors of wave elements.
These are the long-term combined precipitation and particulate
fouling (P&PF) tests in cooling tower systems [5,6].

我是英语新手,问一个问题.
Have your mechanics finished?这是一个完成时.意思是你们的修理工完成了么?
那我用do your mechanics finish?这么表达的话和上面那个完成时的意思一样吧?我只是想搞清楚完成时的句子用一般过去时可以不可以表达...
我用错了，应该是did your mechanics finish?
一般过去时的这个和完成时的意思不一样么？不都是 你们的机械工完成了么？我笨。SORRY。
