日记学英语篇一：用英文写的日记

用英文写的日记

用英文写是提高我们的英文写作能力的一个有效途径，它可以帮助我们养成用英文思考的习惯。几乎所有的学生在刚开始时都不知道写什么。我就有同感。但我在开始时就只是写下任何当时出现在我脑海里的东西。如果遇到我不会表达的词就去查字典。就这样，第二天我坚持写下去。然后以后天天写一些东西。也许刚开始我写的东西不能称做是文章，甚至连句子都不是。这也没关系，我知道要想习惯用另一种不同的方式思考是要花一些时间的。我相信时间会证明我的努力不会白费。

Keeping a Diary in English

Keeping a diary in English is one of the effective ways to improve our English writing ability. It can help us develop the habit of thinking in English. Almost all students don't know what to write in English at the beginning. I had the same experience.

But I just keep writing down everything happened to be in my mind. I will turn to a dictionary if I come across any words that I don't know how to express. The second day, I just do the same. Then I keep on writing every day. Maybe the things I write at first cannot be called an article, or even a sentence. It doesn't matter. I do understand that it needs time to get myself used to thinking in a different way. Time can prove my efforts will not end in vain.

In order to comprehend my molecular optical properties in a theoretically level and complete my paper better, I find a CTsummarize in Chem. Rev. to eich myself. There are more than one hundred pages in this paper, I can only read slowly because of its intricate details. However, I found myself understanding it bit by bit with every word. I realized that there are several hypotheses so far, the TICT (twisted intramaolecular charge-transfer) was agree with my molecular case which has a dual fluorescence in polymorphism. I hope I can make the mechanism clear by further research.

To complete my target today, I study more about CT (charge transfer). When it comes to intramolecular processes, it was always called ICT for short. A CT state can be achieved by an Electron-transfer (ET) reaction or a optical excitation. Many hypotheses were formulated in competitiontry to make clear the mechanism of whether generate a CT state. TICT (twisted intramaolecular charge-transfer) was the most competitive one, I hope I can apply into my data tomorrow.

晶体是一种有序排列的固态聚集态。培养有机分子的单晶对于理解分子在自然状态下的构象非常有用。通常通过单晶XRD衍射来测试晶体的衍射信号，再通过软件计算得到直观的数据。一般要求样品有较好的透明度，并且在XYZ三个方向有一定的厚度。今天，我为组内的同学挑选了测试用的晶体，希望能够帮助他们得到好的数据。

Crystal is a special solid state with molecular ranging regularity.

Preparation of crystal is very important to understanding the molecular conformation of solid state better and we can analyze the connection between conformation and character. We can get diffraction signal by the X-ray single crystal diffractometer, follow on calculate with software. Normally, it require the sample has a preferable pellucidity and a certain thickness on direction X, Y, Z. I gave assistance to my group members with sorting the high quality crystal to be test, hoping they can get a useful data.

Raman spectra (RS)is a spectroscopy based on inelastic scattering discovered by C. V. Raman. Combination of RS and IR (infrared spectroscopy)was very useful in chemistry, physics, biochemistry, etc. Today, I analyzed my synchronization RS under high pressure. The RS gave us the evidence that the molecule conformation becoming more flat with pressure rising. We could get clear the connection between the character and conformation, which is one of the fundamental question of chemistry.

有机小分子的晶体可以通过(转载于:wwW.zHaoQt.NEt 蒲 公 英 文 摘:日记学英语)多种方法培养，挥发法，扩散法，升华法等等。其中，挥发法最为简单，化合物的饱和溶剂在容积不断挥发的情况下，不断达到过饱和状态，化合物析出形成晶体。扩散法最为常用，密封容器中两种沸点相差大的有机溶剂，低沸点的溶剂挥发进入

高沸点的溶剂，降低化合物的溶解度。升华法一般适合分子间作用力较强的化合物，通过减压或者同入惰性气体推动分子移动，并在晶核上累积形成晶体。今天我通过扩散法尝试培养了晶体，希望能够培养出可以得到衍射信号的晶体。

Small organic molecules crystal can be prepared by various means, volatilization method, diffusion method, sublimation method. Volatilization method was the simplest one, saturated solution of compound became supersaturation with solvent volatilizing. Diffusion method was the common used, two organic solvent with different boiling point in sealed container, the solubility would reduce with low boiling point solvent diffusing into high boiling point solvent. Sublimation method usually was used in strong intermolecular forces compound, with inert gas or negative pressure as driving force, molecular piled up on crystal nucleus. Today I try to prepared crystal by diffusion method, expecting to get a crystal which could give a diffraction signal.

Today I read some literature about charge transfer. In terms of state binding energy, the excited states in organic molecular systems can be mainly divided into two types, the strongly boundLE state and the weakly bound charge-transfer (CT) state.LE, as a common state in organic light-emitting molecules, isa highly efficient radiative state, arising from its large transition moment with a larger orbital overlap. The CT

state,pictorialized as a pair of Coulomb bound holes and electrons,staying on the donor and acceptor parts respectively, shows avery low fluorescent efficiency, due to the forbidden electronictransition from the total spatial separation of orbitals.

Considering my paper and future research content, I felt my lack of photochemistry. Thus, I search some treatises to eich myself, one of them is <Photochemical basis>, written by Rohatgi-Mukherjee，K.K., a female Indian scientist. In this treatises, it tells general fundamentals of photochemistry in a lucid way, make the reader understand easily. Even though it was publish in 1991, the basis of the subject is correct. Another reason for me to choose this book is that the blank of academic book in our country. High-quality academic books are usually edited by foreign or translated from foreign. I thought it shows our academic missing something much or less, maybe we should do academic more down-to-earth, only a personal opinion.

今天向师兄讲解了文章的方向，通过和师兄的讨论，发现了已定方向的不足。并且通过进一步的讨论，确定了新的文章主题，多晶型。在光电小分子中，有两种通用的方法调节分子的光学性质。一是通过化学合成，改变化合物的分子结构，二是通过改变分子的堆积状态调节化合物的性质。显然，通过改变分子的堆积来调节更加节省资源。其

中多晶型就是一个不同的堆积方式导致性质变化的例子。通过多晶型的研究，将使调节堆积的方式改变化合物性能成为可能。

In photoelectric small molecules, there are two general methods to adjust the optical properties of molecules. It is by chemical synthesis, change the molecular structure of compounds, the other is by changing the molecular packing. Obviously, by changing the packing of molecules can save more resources. The polymorphism is one classic way of adjusting the character by changing the packing, through the study of polymorphism model may make second way come to reality.

I read a polymorphism literature use for reference. Mechanochromic organic molecules (MOMs), which change their intrinsic optical properties in response to external stimuli such as mechanical grinding and pressure, have sparked tremendous interest because of their potential for various applications involving sensors, memory devices, and optical displays. A promising strategy to tune the optical properties of MOMs is control of molecular packing, because solid-state optical properties strongly depend on molecular packing arrangements.

Polymorphs are different crystalline modifications of the same chemical substance. When different conformers of the same molecule occur in different crystal forms, the phenomenon is termed conformational polymorphism. Occasionally, morethan one conformer is present in the

日记学英语篇三：journal英文日记

Last Wednesday I had dinner with my friends because of Chinese New Year. Even thought I had class on that day, I was excited about the celebration. This was my first year didn’t stay at home with my family actually. I have a lot of friends in NY, but I still felt empty, especially when the date is festival. I really miss my family. The only way I can release my missing was being serious to pass the festival. So I spent a lot of time to prepare Chinese New Year. Chinese New Year is the most important festival in China. As far as I ‘m concerned we should take is seriously, then I did.

First, we need prepare something before Chinese New Year. I bought new clothes for Chinese New Year. Why do we need new clothes? We should wearing new clothes when we are celebrating. That meaning is we have a new start in Chinese New Year. Also we believe that it can bring us good lucky during the whole year. As you know, the best color of clothes is red; we need to wear some thing is red. Red, is representing good lucky, happiness, and passion in China. Therefore, you will see many things are red during Chinese New Year, such as spring festival couplets, New Year paintings or lantern. Another important thing is spring clearing. Spring clearing is very old custom. For us, the dust is relate with ‘old’, therefore, cleaning our house and sweeping the dust mean to farewell the ‘old’ and usher in the ‘new’.

Actually, Chinese New Year not just one day; it is cost 15 days. As usual we have celebration lasts for 15 days, but the first three days are important. The first day of Chinese New Year we should stay with our family that it is mean we will be together forever and happiness. Our dinner’s cuisines are including dumplings, chicken, and pork. The funny thing is we will put a coin into one dumpling. If you ate the

dumplings has a coin, you will be lucky for a whole year. As a result, I made a lot of dumplings with my friends. I think that receive a red bag is the most happy thing for us. Otherwise, we can’t say bad word. During the Spring Festival, one must be extremely careful in our acts and words Because Chinese people want to have a good start at the beginning of each year. Therefore there are many taboos during Chinese New Year. Some words should not be spoken and some things should not be done. After the first three days, we will visit our relative and friends. We must bring some gifts for them. It is mean we share happiness. Also the older people will give a red bar to younger people.

Even though it sounds have a lot of troublesome; we still really enjoy it. We believe in Chinese New Year. We believe that if we have a good start for Chinese New Year then we will acquire a lot of happiness. In the end, happy Chinese New Year!
