The invention provides a method for homopolymerizing conjugated dialkene or co-polymerizing conjugated dialkene and monovinyl aromatic hydrocarbon. The method comprises the following steps: the conjugated dialkene is homopolymerized or the conjugated dialkene and the monvinyl aromatic hydrocarbon are co-polymerized randomly. The method is characterized in that at least one alkali metal alkoxide compound expressed by the formula is used as a structure regulator; in the formula, R is linear chain or branched chain alkylidene radical having 1 to 10 carbon atoms; M is alkali metal selected from Li, Na, K, Rb and Cs.

In our experimental results, we have transferred the GaAs solar cells from GaAs substrates onto the mirror-coated copper substrates with the base layer thickness of 1.5 μm. The photovoltaic performance of the orginal GaAs solar cell on a GaAs substrate was also measured. Under AM1.5G and without anti-reflective coatings conditions, it is found that the Jsc can increase from 12.6 mA/cm2 to 13.82 mA/cm2, while the conversion efficiency can improve from 7.91% to 8.53%. As a result, the enhanced Jsc and η data of the GaAs solar cells can be contributed by the AuGe/Au mirror between the GaAs solar cell and copper substrate.

在实验验证方面，本实验室将砷化镓太阳电池由砷化镓基板转移至铜基板上，在基极厚度1.5 μm、AM 1.5G、以及元件未披覆抗反射膜的条件下，短路电流密度可由12.6 mA/cm2提升至13.82 mA/cm2，增加9.7%，而转换效率则可由7.91%提升为8.53%，这结果显示当砷化镓太阳电池基极底部镀有金属反射层时，的确能适度地提升太阳电池的短路电流密度及转换效率。

A total of 614 sediment samples at an interval of about 1.5 m from all 5 sites of the Integrated Ocean Drilling Program Expedition 311 on Cascadia Margin, northwestern Pacific were analyzed using a Beckman Coulter LS230 Particle Analyzer. The grainsize data were then plotted against depth and compared with other potential proxies of gas hydrateoccurrence such as soupy/mousselike fabrics in sedimentary textures, gas hydrate concentration derived from LWD data using Archie's relation, IR core images and the recovered samples of gas hydratebearing sediments.

对取自IODP 311航次（东北太平洋Cascadia大陆边缘）所有5个站位、采样间距约为1.5 m的614件沉积物样品，利用Beckman Coulter LS230激光粒度仪进行了沉积物粒度分析，获得了沉积物粒度随深度变化特征，进而与水合物层位的替代指标进行了位置对比，这些指标包括特殊沉积构造（soupy和mousselike构造）、测井数据推算出来的水合物饱和度、岩芯红外图像和实际钻取的含水合物沉积物等。

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。
