Methyl Sartortuoate and Methyl isosartortuoate are two tetracyclic tetraterpenoids isolated from the sarcophyton tortuosum tixier-durivalt by Chinese scientists. Biogenetically, it could be regarded as a Diels-Alder combination of two cembrenoids, i.

扭曲肉芝甲酯和异扭曲肉芝甲酯是中国科学家从南中国海扭曲肉芝软珊瑚中分离到的一种四环四萜化合物，从生源角度考虑，可能由两个西松烷型二萜化合物经Diels-Alder反应组装而成。

White coral is often bleached to brighten its color.

白珊瑚漂白往往是照亮它的颜色。

There are Brachiopoda, Anchozoa, Trilobita, Crinoidea et al. fossils in the clastic rocks and Iimestone.

碎屑岩及灰岩中含腕足、珊瑚、三叶虫、海百合茎等生物化石。

Cells have not blocked the evolution of extremely long life spans, like that of the bristlecone pine, which lives 5,000 years, or certain deep sea corals, whose age has been found to exceed 4,000 years.

细胞没有阻挡寿命极长的演变一样，美国西南部的松树有5000年的生命，或某些深海珊瑚，其年龄已发现超过4000年。

The light insensitivity type includes Ipomoea batatas 'Aurea' and Epipremnum aureum. The light sensitivity type includes Celtis julianae 'Aurea', Gleditsia triacanthos 'Sunburst', Sophora japonica 'Aurea', Physocarpus opulifolius 'Aurea', Cornus alba 'Aurea', Ligustrum lucidum 'Aurea', Spiraea×bumalda'Goldmound', Berberis thunbergii 'Aurea', and the light high-sensitivity type includes Sambucus glauca 'Aurea', Caryopteris×Clandonensis 'Worcester Gold', Forsythia koreana 'Suwon Gold'.

光强不敏感型的有金叶红薯，金叶绿萝，二者均起源于热带；光强敏感型的有金叶珊瑚朴，金叶皂荚，金叶国槐，金叶风箱果，金叶红瑞木，金叶女贞，金山绣线菊，金叶小檗，绝大多数起源于暖温带；光强高度敏感型的有金叶接骨木，金叶莸，金叶连翘，起源于温带。

Result The dust-retention amounts per unit area and the dust-retention amounts per plant of different tree species had bigger difference. Among trees, the dust-retention abilities of Ligustrum lucidum, Platycladus orientalis, Cedrus deodare, Platanus hispauiea anti Spohora japonica were stronger. Among shrubs, the dust-retention abilities of Viburnum odoratissimum, Pittosporum tobira, Euonymus japonicus and Lagerstroemia indica were stronger.

结果］不同树种的单位面积滞尘量、单株树木滞尘量均存在较大差异，乔木中，以女贞、侧柏、雪松、悬铃木和国槐的滞尘能力较强；灌木中，以珊瑚树、海桐、大叶黄杨和紫薇等的滞尘能力较强。

So , we can plant Celtis julianae 'Aurea' under 80% light intensity.

因此，在保持金叶珊瑚朴金黄色叶色的前提下，可以适当降低栽培环境的光强至全光照的80%，以提高净光合速率，为树体贮存更多的营养。

With the light intensity decreased, the total chlorophyll , chla and chlb content of Celtis julianae 'Aurea' increased, especially chlb rising rapidly.

随着光强的降低，金叶珊瑚朴的总叶绿素、叶绿素a和叶绿素b含量都有所增加，且以chlb含量的增加更为显著。

The light obsorbed by Celtis julianae 'Aurea' was mainly used in photochemical reaction and it had higher photochemical activity and electron-transferring rate.

金叶珊瑚朴所吸收的光能主要用于光化学反应，具有较高的光化学活性，且电子传递速率较快，光能利用率高。

The results showed that Celtis julianae 'Aurea' belongs to chl-deficient type. The main cause of turning yellow was the blockage of chlorophyll biosynthesis which could be somewhere in the formation of Pchlide.

导致金叶珊瑚朴叶色金黄的原因是叶绿素的合成受阻，受阻部位可能在Mg插入卟啉环后合成原叶绿素酯时。

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.

交际能力和语法的关系应该是目标与途径的关系。
