In this post, I want to share some tips on writing papers using $\LaTeX$.
In certain cases, two piece of texts must be close to each other and not appear
in different lines, e.g., when you refer to an image or a table. This is when
non-breakable space
comes to help. In LaTeX, you can insert a non-breakable space with ~. For
example, to refer to some figure you have defined, you can use the following:
The figure~\ref{fig:some_fig} shows an interesting result.This will make sure that figure will always be followed by the index number
in the same line.
LaTeX use different width of space between words in a sentence and between two sentences. Typically, a lower case letter followed by a dot ends a sentence. An upper case letter followed by a dot is some kind of an acronym and is not considered end of sentence. When these rules are broken, you need to tell LaTeX whether there is an inter-word space or a inter-sentence space.
If a dot follows a lower case letter and it is not the end of a sentence, you
should follow the dot with an inter-word space (\ ):
The book is first published in the Combin.\ Journal.For phrases such as Prof. Adam, a non-breakable space is more appropriate:
If a dot follows an upper case letter and it is indeed the end of a sentence,
you should precede the dot with \@:
WHO is a world orgnization, just like WTO\@.\textit for emphasizing text#Some people like to use \textit for emphasizing text. Although this works
most of the time, it is not encouraged. For example, what if you want to
emphasize text inside \textit command? To emphasize text, you should use
\emph{} which is dedicated to do this job and does it well.
If you use chktex, you may see warnings like the following:
command terminated with space
That is because if a command does not terminate with a space, the space after it may be ignored by LaTeX.
Good: \LaTeX{} is great.
Bad: \LaTeX is great.In short, spaces before the opening parentheses is necessary. If you do not need comma or dot, space after closing parentheses is also necessary. In the enclosed text, there is no need to add spaces in the two ends.

will find the opening quotation is apparently wrong. The correct way to
represent double quotation is ``some text''.
The correct way to use single quotation is `some text'.
