THE FIRST TOTAL SYNTHESIS OF TAXAMAIRIN B Taxamairin B, representive of rare naturally-occuring rearrang-ed 9(10→20)-abeo-8, 11, 13-triene diterpenoids, has been firstsynthesized by a eleven-step route in an overall yield of 8.19%,starting from commercially available catechol and 1,3-cyclohexan-dione. The improved Friedel-Crafts annulation, thermodynamicallycontrolled-geminal pairing methylation, the selective oxidation ofallyl group and the selective reduction of the less-hindrancecarbon-carbon double bond are the key steps.

二。美丽红豆杉素B的全合成研究 1，美丽红豆杉素B的首次全合成以价廉，易得的邻苯二酚和1，3-环己二酮为原料，经过改良的Friedel-Crafts烷基化反应，热力学控制的α，β-不饱和酮结构的α一位双烷基化，烯丙位的选择性氧化，以及选择性还原位阻较小的碳碳双键等十一步反应，以8.19％的总收率首次完成了美丽红豆杉素B的全合成。

Under contented the used intensity,the anorthite ceramic substrate which prepared with pyrophyllite at low-sintering temperature has small dielectric constant,good dielectric property which compared with common aluminum substrate,the anorthite ceramic substrate has light bulk density,which is advantage to reduc.

研究了用叶蜡石、碳酸钙与适量的氧化铝，在加入添加剂的条件下，用原位反应烧结法制备出低温烧结( 12 0 0℃)的新型钙长石质陶瓷基片材料。

The long period antiphase structures and the antiphase domains have been cbserved atthe single diffracted vector g.

用电子衍衬和能谱作原位观察，发现晶界出现溶质原子偏聚和位错缠结，晶内有序区出现周期性层错。

The result of ISH indicate that the FIE gene has specialspatio-temporal expression in apomixis E.binata during the reproduction growth andcontrols the development of embryo and endosperm.

原位杂交的结果表明FIE在龙须草生殖发育的过程中特异的时空表达，与雌雄配子体发育有关，并参与调节胚和胚乳的发育。

Methods All severed composite tissues of 48 cases were replanted in situ through artery and vein anastomosis or vena arterialization.

对48 例离断复合组织块采用缝合动脉主干或分支、静脉或静脉动脉化进行原位再植。

Just as he reached it, a shot boomed from the cannon, deafening him and his suite, and in the smoke that suddenly enveloped the cannon the artillerymen could be seen hauling at the cannon, dragging and rolling it back to its former position.

当他快要走到时，这门大炮中传出隆隆的炮声，把他和侍从们震得发聋，在那骤然缭绕大炮的硝烟中，可以看见，几名托着大炮的炮兵，他们急忙地使尽全力，将大炮推回原位。

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.
