用英文寫的日記

用英文寫是提高我們的英文寫作能力的一個(gè)有效途徑，它可以幫助我們養(yǎng)成用英文思考的習(xí)慣。幾乎所有的學(xué)生在剛開始時(shí)都不知道寫什么。我就有同感。但我在開始時(shí)就只是寫下任何當(dāng)時(shí)出現(xiàn)在我腦海里的東西。如果遇到我不會(huì)表達(dá)的詞就去查字典。就這樣，第二天我堅(jiān)持寫下去。然后以后天天寫一些東西。也許剛開始我寫的東西不能稱做是文章，甚至連句子都不是。這也沒關(guān)系，我知道要想習(xí)慣用另一種不同的方式思考是要花一些時(shí)間的。我相信時(shí)間會(huì)證明我的努力不會(huì)白費(fèi)。

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.

晶體是一種有序排列的固態(tài)聚集態(tài)。培養(yǎng)有機(jī)分子的單晶對(duì)于理解分子在自然狀態(tài)下的構(gòu)象非常有用。通常通過單晶XRD衍射來測(cè)試晶體的衍射信號(hào)，再通過軟件計(jì)算得到直觀的數(shù)據(jù)。一般要求樣品有較好的透明度，并且在XYZ三個(gè)方向有一定的厚度。今天，我為組內(nèi)的同學(xué)挑選了測(cè)試用的晶體，希望能夠幫助他們得到好的數(shù)據(jù)。

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.

有機(jī)小分子的晶體可以通過(轉(zhuǎn)載于:www.newchangjing.com 蒲 公 英 文 摘:日記學(xué)英語(yǔ))多種方法培養(yǎng)，揮發(fā)法，擴(kuò)散法，升華法等等。其中，揮發(fā)法最為簡(jiǎn)單，化合物的飽和溶劑在容積不斷揮發(fā)的情況下，不斷達(dá)到過飽和狀態(tài)，化合物析出形成晶體。擴(kuò)散法最為常用，密封容器中兩種沸點(diǎn)相差大的有機(jī)溶劑，低沸點(diǎn)的溶劑揮發(fā)進(jìn)入

高沸點(diǎn)的溶劑，降低化合物的溶解度。升華法一般適合分子間作用力較強(qiáng)的化合物，通過減壓或者同入惰性氣體推動(dòng)分子移動(dòng)，并在晶核上累積形成晶體。今天我通過擴(kuò)散法嘗試培養(yǎng)了晶體，希望能夠培養(yǎng)出可以得到衍射信號(hào)的晶體。

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.

今天向師兄講解了文章的方向，通過和師兄的討論，發(fā)現(xiàn)了已定方向的不足。并且通過進(jìn)一步的討論，確定了新的文章主題，多晶型。在光電小分子中，有兩種通用的方法調(diào)節(jié)分子的光學(xué)性質(zhì)。一是通過化學(xué)合成，改變化合物的分子結(jié)構(gòu)，二是通過改變分子的堆積狀態(tài)調(diào)節(jié)化合物的性質(zhì)。顯然，通過改變分子的堆積來調(diào)節(jié)更加節(jié)省資源。其

中多晶型就是一個(gè)不同的堆積方式導(dǎo)致性質(zhì)變化的例子。通過多晶型的研究，將使調(diào)節(jié)堆積的方式改變化合物性能成為可能。

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

日記學(xué)英語(yǔ)篇三：journal英文日記

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!
