谁能翻译这道题：A closed surface in theform of cylinder of rudius R,immersed ina uniform electric field E,with the cylinder asxis parallel to thefield.wath is the flux Ø of the eletric field through this closed surface?

帮忙看看是不是倒装
It cuts a clean cylinder of rock,from which can be seen the strata the drill has been cutting through.
从句是不是用了倒装?
正常语序是不是应该是It ...,from which the strata the drill has been cutting through can be seen.

在英文里面35mm怎么读,要正确的,比方说 and the diameter of the cylinder is 35mm.

英语翻译
(e) at any point of the working cycle,cylinder charge pressure
and temperature are completely uniform,i.e.spatial variations
in their values as for instance during combustion or scavenging,
are completely neglected.
The most commonly used air-standard cycles are as follows
(Figures 1.7'a,b and c):
(a) The constant pressure or diesel cycle (Figure 1.7a)
Here combustion is simulated by constant pressure heat addition

1.The weight of a cylinder varies as the square of the diameter when the height is constant,it also varies as the height if the diameter remains constant.Two cylinders have their oheights is the ratio 49:72.Find the ratio of their diameter if the weight of the first is twice that of the second.
2.Given that x varies as the cube of y when z is constant ,and x varies as z when y is constant and also that 5x=z when y=1,find the equation connecting x ,y and z.

英语翻译
Point with the end of the cylinder only in an area where no person is located,in case the tool will be broken during pressing.

英语翻译
a cylinder is subdivided around the z axis into slices,and along the z axis into stacks.//
