Our group is interested in plant secondary metabolism and cotton biology. Current research projects include characterization of transcription factors and small RNAs involved in controlling cotton fiber and Arabidopsis development; investigation of terpenoid biosynthesis, particularly in Artemisia annua; and genetic engineering of cotton fiber development, plant resistance to insects, and artemisinin production.

利用遗传学、发育生物学、生物化学和分子生物学等手段克隆和鉴定参与叶形态建成的重要基因，解析它们之间的互作关系，了解叶形态建成的基因调控网络，认识叶形态建成的分子调控机理，为创制具有理想叶片形态的作物遗传改良品种提供理论基础和技术支撑。

The shape memory effect of poly{2,5-bis[(4-butoxyphenyl)oxycarbonyl]-styrenes} fiber was studied by TA-Q800 Dynamic Mechanical Analysis. According to the research results, the outstanding shape recovery ability of PBPCS fiber was found. The recovery rate was fastest above 145℃. It cost about 9 minutes recovering from 400% strain to origin length. The repeatability of shape memory was good in 5 repeated times.

本文采用TA-Q800动态热机械分析仪研究了聚乙烯基对苯二甲酸二酯纤维的形变回复性能，发现PBPCS纤维具有非常好的形状记忆效应，在145℃及以上温度，形状回复速率最好，9min左右可以从400％的伸长回复到原来的尺寸，于145℃，重复实验5次，结果说明形变回复重复性好。

In this approach, the optical Mach-Zehnder intensity modulator is biased to suppress the odd-order optical sidebands, the fiber laser operates in the second-order rational harmonic mode, and a fiber Bragg grating notch filter is used to block the optical carrier.

这种方法的原理是：调节强度调制器的偏置使其抑制奇数阶谐波的产生，同时使激光器工作在二阶有理数锁模状态，最后用一个光纤光栅消除载波。

A Design of PMD emulator made of polarization controller using fiber squeezers is proposed in this thesis, which consists of two polarization controllers using fiber squeezers and two segments of high birefringence fibers, and is controlled by a micro-controller unit.

本文提出了一种利用光纤挤压式偏振控制器构成的 PMD 模拟器的设计方案，它由两个光纤挤压式偏振控制器和两段高双折射光纤组成，通过单片机进行控制。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
