The decomposition of chromosome was a main problem in construction of BAC library. DNA discompose would be avoided or decreased by adjustments of component and pH of chromosome extraction buffer or pre-electrophoresis for 6-8h before digestion. Identification of inter-species hybrids was a necessary step for creating a new germplasm. Two samples were selected from offspring of hybridization and backcross of a cross between cabbage and Chinese cabbage.

鉴定种间杂种是利用远缘杂交创造新种质时的一项重要工作，本研究运用细胞核DNA含量流式测定技术，对甘蓝和白菜杂交及回交各世代的DNA含量进行检测，以监控遗传物质在不同材料间的流向，并从回交二代植株群体中筛选了两个材料，具有和白菜差异不显著的DNA含量，可推断其为核质杂种。

The evolution of the Youjiang basin in the Triassic shows that it is not a "regenerated geosyncline" as thought in traditional view, but constitutes a complete Wilson- Cycle with its earlier development in the late Palaeozoic.

4认为三叠纪右江盆地不是传统观点所说的"再生地槽"，而是与晚古生代一起共同构成一个完整的威尔逊旋回—处于晚古生代多岛洋体系格局的最终封闭阶段。

An algorithm is established for compensating springback in sheet metal forming based on the theories of linearity closed loop control system, space Fourier transform, and transfer function in frequency domain as well as die experiment iteration.

以冲压件回弹引起的尺寸误差为控制目标，以线性闭环控制系统、空间Fourier变换和频域传递函数为理论基础，基于模具实验迭代，建立了模具回弹补偿修正算法。

Four stages of granitoid plutonism took place in Precambrian, early Paleozoic （∈-D3）, late Paleozoic-early Mesozoic （D3-T3）, and late Mesozoic-Cenozoic, respectively.

该带内的花岗岩形成可以划分为4个时段，分别与4个造山旋回相对应：前寒武纪；早古生代；晚古生代—早中生代；晚中生代—新生代。

The basin experienced three basin-forming cycles of Neopaleozoic, Mesozoic and Cenozoic Eras. Mesozoic fault and depression compounding basin composed the northern margin Jurassic petroleum system and the Cenozoic large-scale strike-slip and compressional basins composed the Tertiary petroleum system of the western Qaidam basin and Quaternary petroleum system of Sanhu. The intense tectogenesis of Yanshan and Xishan made the Jurassic petroleum system of the northern Qaidam more complex. The monocycle paleoclimate evolution in Cenozoic Era and multi-tectonic movement made the lake-basin evolution, hydrocarbon source-rock, reservoir development, accumulation condition and petroleum distribution are more exceptive in character and complex in feature.

该盆地经历了晚古生代、中生代和新生代3个成盆旋回，中生代断坳复合盆地形成了柴达木盆地北缘侏罗系油气系统，新生代大型走滑挤压盆地形成了柴达木盆地西部第三系油气系统和三湖第四系天然气系统，燕山和喜山2期强烈构造运动使柴北缘侏罗系油气系统高度复杂化，新生代单旋回古气候演化与多期构造运动使湖盆演化、烃源岩和沉积储层发育特征、成藏条件与油气分布规律变得十分特殊和复杂。

ABSTRACT: Shallowing-upward carbonate cycles in the~2650 Ma Cheshire Formation, Belingwe greenstone belt, closely re- semble their Proterozoic and Phanerozoic counterparts.

问题补充：在津巴布韦贝林圭绿石带的26.5亿年的Cheshire组中向上变浅的碳酸盐旋回极相似于元古代和显生代的碳酸盐旋回。

Six plants of BC2F1 pyramiding Xa23 and IPT genes were further obtained in the combinations of "[(9311/// He'xi 15/CBB23//GC-1) 9311] 9311","[(E32/// He'xi 15/CBB23//GC-1) E32] E32". After backcrossed and self-crossed 1~2nd, the plants pyramiding Xa23 and IPT genes can be used in program of hybrid rice breeding.

携带IPT基因的抗病植株再与杂交稻亲本进行回交，在2个BC2回交组合&[（9311///合系15/CBB23//GC-1） 9311] 9311&和&[（E32///合系15/CBB23//GC-1） E32] E32&中获得了7株携带IPT基因与Xa23基因的植株，这些植株再经过1~2代回交和自交，即可用于杂交稻育种。

Dazicao,a native wheat variety with stripe rust resistance from Henan,China,was crossed with susceptible cultivar Mingxian 169 as the female parent.The F1 progeny was selfed to produce F2 progeny and backcrossed with Mingxian 169 to produce BC1 progeny.

以抗条锈病的农家品种大籽糙作父本、感病品种铭贤169作母本杂交获得F1代杂交种，F1代植株自交获得F2代种子，F1代植株与铭贤169回交获得 BC1代种子。
