Microstructural studies of three types of tectonites from eastern Liaoning area with different deformation characteristics (gneissic, banded and mylonitic structures) by means of microstructural analysis, transmission electron microscope analysis shows us they have different microstructures and Submicrostructures.

通过显微和亚微分析揭示出辽东地区三种变形特点的角闪质岩石（片麻状斜长角闪岩、条带状斜长角闪岩和糜棱状斜长角闪岩）具有差异的显微及亚微构造。

The acorn production of this oak appears masting,and the masting is complicated at the level ofpopulation and individual.

辽东栎的结实具有大年现象，大年现象十分复杂，在种群水平、个体之间都存在差异。

The seed production of Quercus wutaishanica is important for the regeneration and restoration of its population.

辽东栎种子产量对其种群更新和恢复具有重要意义。

Fines tabulaeformis forest and Quercus liaotengensis forest are among the most important vegetation in warm temperate region in China.

According to the SLA and LDMC of tree layer, the five communities can be classified into three groups: the first group consists of Betula dahurica and Populus davidiana, the second group contains mainly Quercus liaotungensis, and the third group consists of Juglans mandshurica and Tilia mandshurica.

依据乔木层的SLA和LDMC将5种群落分成3类，第一类是黑桦林和山杨林，第二类是辽东栎林，第三类是胡桃楸林和糠椴林。

These pollen maps show significant vegetation changes during the past 10 000 years in the current forest regions of Northeast China, with the early Holocene characterized by the widely distributed Birch, the mid-Holocene by the development of temperate deciduous forest mainly consisting of Quercus and Ulmus, and the late Holocene by the marked increase in Pinus abun dance and the development of temperate mixed conifer and deciduous forest.

花粉图展示了东北地区植被演化的主要特征。桦树在全新世初期遍布从三江平原到辽东半岛南端的东北东部地区，在森林中占据绝对优势地位；榆属和栎属等阔叶乔木在早中全新世的大部分时间内是东部森林中的主要种类；在大约5kaBP以后，松属在东北现在的森林地区开始增加，云、冷杉属也表现出较明显扩大，中北部地区的森林覆盖度可能比原来增大了。

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