成功构建了重组腺病毒 Ad-RUmIL-12，可以通过RU486诱导mIL-12单链融合蛋白的表达，为下一步体内基因治疗奠定了良好的基础。

Barley yellow dwarf virus is reported to be the most important viral pathogen of cereals worldwide. In fact, BYDV is a group of at least five luteoviruses that cause similar symptoms in cereals but can be distinguished serologically and on the basis of vector specificity.

禾谷类作物的黄矮病是由大麦黄矮病毒(Barley yellow dwarf virus，简称BYDV)的侵染所引起的，在世界各国均有发生，由蚜虫进行循环性的永久传播。

The FEM, whose process is very *** and is fit to deal with complex boundary condition, is used to simulate the frequency-domain IP. Studying the characters and laws of IP\'parameters under different measuring devices and undulate topography will provide scientific references and basis and reduce the multiplicities of interpretation. It is will be an attempt and exploration.Because of the frequency of the exciting currents is usually between 10-2～102 Hz, the vector A can be seen is not change with the time and the EM effect can be ignored in the low frequency.

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。
