I found a sentence in this scientific article (last-but-one pharagraph) I have trouble with understanding it:
In addition we think the accumulation that there is energy in the centre of light beam of Bessell where energy is lower in intensity.
It just seems broken english to me. AFAIK, "accumulation" means gradual gathering, so I'd expect the structure be like
"the accumulation that (...) results in (...)" But the second half seems to be missing. (and to me the tense of the whole pharagraph seems to be off...)
Could you explain me what they wanted to say there?
edit: never mind, that article is 100% rubbish as is.
However, the ability of Bessell’s light beam is cutting quality and side wall shape and receiving quite good result. In fact, it contributes to dispersing and accumulating energy to the laser orbit of large area that the pulse width of second flies. In addition, we think the accumulation that there is energy in the centre of light beam of Bessell where energy is lower in intensity. Prove very successful to make the stealthy cut of the sapphire with Bessell’s light beam too.
