명확한 페이지의 구성표

2024-6-13 • tag-icon

Lyx를 사용하여 논문을 작성하고 있는데 거의 다 끝났는데 이상한 문제가 생겼습니다. 페이지에 맞지 않으면 그림과 구성표가 새 페이지로 이동되는 경우가 거의 없지만 공간이 있기 때문에 위나 아래에 텍스트가 없는 이유를 이해할 수 없습니다. 때로는 더 큰 수레가 아래에 일부 텍스트와 함께 멋지게 배치되기 때문에 문제가 무엇인지 전혀 알 수 없습니다.

문제가 수레 중 일부에만 닿기 때문에 최소 작업 예제를 구성하는 방법을 모르므로 논문의 일부를 첨부합니다. 구성표 0.3에는 문제가 있지만 비슷한 크기의 구성표 0.5는 괜찮습니다.

\section{Procedures of syntheses}
\end{onehalfspace}

\begin{onehalfspace}
For each compound used as a functional monomer, a number was assigned.
If synthesis of a certain functional monomer required several steps,
the intermediates were labeled with a number of the final product
and a letter. For clarity, the NMR and MS spectra as well as crystallographic
data are given in Appendix.

\subsection{Syntheses of new thiophene derivatives}
\end{onehalfspace}

\begin{onehalfspace}
Within the present research 16 new bis(2,2'-bithiophene) and 2 ten
{[}C60{]}fullerene derivatives were designed and synthesized to serve
as functional monomers (FMs) . Their recognition sites varied from
simple functional groups, such as hydroxyl, amino, nitro, carboxyl,
or amide groups, to bigger assemblies containing naturally occuring
recognizing moieties, such as biotin, thymine, cytosine, or guanine.
Other FMs contained succinimide, \mbox{4-tertbutylcalix{[}6{]}arene},
and pentaethyleneglycol as recognizing sites. Each of the newly prepared
FM contained one recognition site. \vspace{1em}
