I currently use an acrylic gloss varnish to prime my canvases - mainly because it is transparent, and I prefer the natural color of the canvas over the chalky appearance of gesso; I always put three coats on.

i目前使用丙烯酸清漆光泽，以总理我的画布-这主要是因为它是透明的，我更喜欢天然彩色的帆布超过垩外观g esso，我始终把三个大衣。

The lithologic pool such as that developed in the actic region while the basin is rifting or in the glacis region while the basin is depressing all which can be found in this basin. Five kinds of sedimentary facies and thirteen sedimentary parfacies can be found in the Shengbei concave during the period of Jurassic series and Cretaceous series.

在该盆地内部既有可能发育断陷期陡坡带的岩性油气藏，又有可能发育坳陷期缓坡带的岩性油气藏，其胜北洼陷在中侏罗统－白垩系沉积时期主要发育5种陆相沉积相类型、10种沉积亚相类型。

The distribution and its forming condition of sporepollen fossil resedimented inTertiary system in Yilan-Yitong graben are throughly analyzed in this paper.

本文对依兰－伊通地堑第三系再沉积孢粉化石的分布及其形成条件进行了深入的分析，提出了再沉积的孢粉化石来自晚白垩世地层及其主要的鉴别方法。

All these were led by Idomeneus, and by Meriones, peer of murderous Mars.

In working area and its adjacent area, the forming tectonic setting of Indosinian intrusion was that orogenic belt pressed strongly, intracontinental subduction; that of early Yanshan movement epoch was the stress field transferred from compression to extension meanwhile the incrassate crust of orogenic zone turned to extensional collapse; and that of early Cretaceous volcanics was that the area structure extensional collapse further more during the post period of orogenic phase.

研究区及邻区印支期侵入岩形成于造山带强烈挤压陆内俯冲的构造环境；燕山早期侵入岩形成于由挤压转向拉伸、造山带的增厚陆壳开始发生伸展垮塌的构造环境；早白垩世火山岩形成于造山期后进一步发生伸展垮塌的区域构造环境。

Field and pot experiments were conducted by using indica rice varieties with different chalkiness.

以垩白不同的籼稻品种为材料，进行了田间试验和盆钵试验。

Affeted by transgression, three times of lake ingression occured and formed three sets of source rocks of salty enviroment in Subei basin.

受海侵影响，苏北盆地在晚白垩世至古新世曾发生三次湖泛，形成三套半咸化环境的烃源岩系。

Through U-Pb isotope age study in sheeted dike complex, has gained the isochrone age is114-133Ma.The age is early cretaceous,which indicates the time of formation of sheeted dikecomplex.

另外，在该蛇绿岩套中的岩墙群进行了单颗粒锆石U－Pb同位素测年，获得的表面年龄值为 114－133Ma 之间，时代为早白垩世，基本反映了席状岩墙群的成岩年龄。

Based on the analyses of bio-markers and geochemical data, the abundance of organic matter, the construction of biological source, sedimentary environment, maturity and the oil-generating potential of the source rocks in the lower Cretaceous Duoba and Langshan formations in the Cuoqin basin have been studied.

应用生物标志物分析技术，结合其它地化资料，对青藏高原措勤盆地下白垩统多巴组、郎山组烃源岩，进行了有机质的丰度、生源构成、沉积环境、成熟度及成油潜力等方面的初步研究。

Except for HIMU-type OIB with negativeΔ7/4 ratios in the Wandashan massif, all other rocks have positiveΔ7/4 andΔ8/4 values, a feature of the Laurasia continent in the Northern Hemisphere.2 In the southern Hinggan Mountains distributes a Cretaceous felsic igneous rock belt characterized by highly positive-ε_ T_(DM = 0.42～0.64Ga,ε_ =+4.0～+5.9 and radiogenic Pb ~(206Pb/~(204)Pb = 18.36 ~ 18.56 isotope compositions.

除完达山外来拼贴地体的HIMU型OIB具有负的△7/4值，东北地区中生代火成岩都为正的△7/4和△8/4值，显示出亲北方劳亚大陆的岩石圈属性。2在大兴安岭南区林西-霍林河地区存在一条近似平行索伦-贺根山-小兴安岭古缝合带的高ε_早白垩世中酸性火山岩组合。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
