Microspore abortion of H9A occurred in the early uninucleate stage. The tapetum cells were in extreme hypertrophy so that tetrads were extruded to crack and break down and could not form normal uninucleate pollen grains; the abortion type was sporophyte.

结果表明，雄性不育材料H9A的小孢子败育发生在单核前期，由于绒毡层细胞极度膨胀，四分体受挤压后破裂并降解，无法形成正常的单核花粉粒，属于孢子体败育。

On the basis of examination of the wear behavior and worn surface morphology of the coatings after abrasive wear and erosion wear respectively, and the enhancing mechanisms of interlamellar bonding caused by unmelted carbide particles during deposition, the effects of the microstructure on its performance are discussed.

其次，在分析研究了涂层磨粒磨损和冲蚀磨损失效形貌以及未熔化碳化物颗粒对涂层层间结合强化机理的基础上，探讨了磨损机制、磨损模型的建立及涂层结构对磨损性能的影响规律。

Recently, a nearly E-W-striking, over 10 km long albitite zone has been recognized for the first time in the Lower Silurian Meiziya Formation in a Lower Paleozoic lead-zinc ore deposit concentration area of the Xunyang basin, South Qinling. It shows a conformable contact and gradational relationships with the country rocks and has thick-bedded and massive, banded, brecciated structures and fine and very fine equigranular and intraclastic textures. It is chemically characterized by enrichment in SiO2, Al2O3 and Na2O and is rich in the trace elements Fe and Mn and poor in the trace elements Co, Ni and Cu. Its ∑REE, LREE and HREE are lower than those of the country rocks and exhibit pronounced Eu depletion.

最近，在南秦岭旬阳盆地下古生界铅锌矿集区内的志留系梅子垭组地层中首次识别出一条近东西方向延伸长达10余千米的钠长石沉积岩带，与地层整合产出，渐变过渡，厚层块状，条带状，角砾状构造，均粒微-细晶结构，内碎屑结构；其化学成分以富含SiO2，Al2O3及Na2O为特征，富Fe，Mn，贫Co，Ni，Cu等微量元素；该钠长石岩的∑REE，LREE，HREE均较围岩偏低，具明显Eu亏损的特征。

Also the sedimentary model of 34 sand body was established as aphanitic sandy anastomosed stream.

确定了34小层砂体为细粒砂质辫状河沉积模式。

The CO2 saturation point and light saturation point of B ascended and CO2 assimilatory ability, efficienecy of light energy utilization and temperature effect increased.

低钾处理初期，B叶绿体基粒数多于A，并且片层密度加厚；低钾处理后期，B与A叶绿体结构与形态趋向一致。B的CO2饱和点上升、光饱和点上升，CO2同化能力增加及光能利用率、温度效应增加。

The aberrant phenotypes were observed in the anther of tobaccotransformed with ZM401 sense construct: the inflorescence growth and floral axiselongation are suppressed; the flower buds falling or flowers abscission earlier wereobserved. The degradation of tapetum are not observed at the binucleate pollen stagewhich corresponds to the mature stage, although the tapetal cells of untransformedtobacco anther at the same stage have already degenerated completely anddisappeared.

对转基因烟草进行形态学、组织学分析结果表明，ZM401基因以反向方式整合的转基因烟草表现一切正常，而含有ZM401正义基因的转基因烟草在表型和组织学上都出现了异常：花序生长缓慢，花序轴变短，生长过程中花逐渐脱落，花序轴褐化枯死；花药绒毡层退化延迟，药室内壁在雄配子体发育后期不能进行带状加厚，阻碍了花粉粒的释放。

The tectonic rocks along the fault zone are composed of cataclastic rocks and mylonites formed in higher, middle and lower temperature. Respectively, both of structural features and rocks have the features of multiple phase's of deformation. The deformation features of main minerals in the high temperature mylonites show that: the quartz has the form of long single crystal and the fabric feature of point maximum near X axis; the feldspar has the form of recrystallization assemblage, They present a high amphibolite-granulite facies with temperature ＞600℃ and depth ＞20km. The deformation features of mylonites formed in middle temperature show that: the quartz has the form of polycrystal banding and the fabric feature of point maximum near Y axis and small circle girdle with Y rotational axis; the feldspar has the form of a coremantle structure, They reflect a high greenschist-lower amphibolite facies with temperature from 400℃ to 600℃ and depth from 15km to 20km.

其中，高温糜棱岩主要矿物变形特征组合为：石英为长矩状或长条状单晶、组构为近X轴的点极密，长石为几乎完全重结晶的集合体，形成温度＞600℃，相当于高角闪岩—麻粒岩相，形成深度＞20km；中温糜棱岩主要矿物变形特征组合为：石英为多晶条带、组构为近Y轴点极密和以Y轴为旋转轴的小圆环带，长石发育核幔结构，形成温度为400～600℃，相当于高绿片岩—低角闪岩相，形成深度为15～20km；低温糜棱岩主要矿物变形特征组合为：石英发育核幔结构、组构特征为近Z轴点极密，长石以碎裂为主，形成温度＜400℃，相当于中低绿片岩相，形成深度为8～12km；碎裂岩则主要代表了地表浅层的变形。
