My English sucks

Finally, after revisiting the thesis statement several times, it’s time to circulate my draft among the co-authors. The process I have been through this month just revealed that I need my English writing skills to improve badly. When I read the stuff I just wrote, which turned out to be really hard to understand, I was unable to find a clear logic flow behind those phrases. Unfortunately, that is the essential part about writing a scientific paper. Thus I realise I really need to take some time and be serious about my English. Through reading some British or American masterpieces, and mastering some new words, I should improve my English. Besides logic, I found myself often using some useless phrases whose meaning has already been presented before. In one word, I need to simplify my sentences.

Last Sunday, I just finished the PhD qualifying exam for PMO. The exam on galaxies is really hard for me. Maybe that’s because I have forgotten a lot. However, I think the ISM and English parts are not too bad. That means I need to take out some time carefully reading the textbooks on galaxies, for they are the foundations.

In about 2 months, I will graduate as a master in Astrophysics. Good luck to me.

Finish second draft and prepare for the exam

Finally, I finished the revision of my first paper draft. Several changes were involved, including adding a table for interpreting the correlation between the infrared colors with the different line ratios. However, I think more careful data reduction is needed, as some line itself could already have a strong dependence. So the order should be 1. Single lines first; 2. The ratios. Perhaps adding another table just as Table 1 is a good idea, also putting the lines instead of line ratios in the first column. But, the line strength could result from the scaling effect. In fact, Table 1 is connected to Figure 2, which displays the dependence of infrared normalized line luminosities on the IR colors. That means the correlation coefficient in Figure 2 could predict part of the results in the table, though it’s more clear in Table 1. Probably I should mention that in the paper.

Nevertheless, the variation of the slope with different transitions is also an interesting point which I should include in the paper later. The difference may infer the intrinsic variable excitation mechanism.

But now I really have no time until I finish the entrance exam for PMO. I have to heavily prepare 3 subjects in the next 4 days… I have to say it’s real ….by chance, though I have some basic knowledge which I am not sure that I can recall whenever I need it. Anyway, let us cross our fingers…
