The CFD method was applied to calculate and simulate the form and action process of the cavitation at the representative character of the cavitation erosion on the surface of the hydraulic turbines.Some argumentation was presented that micro jet impacted the wall with a certain degree when bubble collapsed with the result that the maximal strain of the wall annularly distributed the local of the boundary touching the micro jet.Cavitation was gradual to develop regionally at the mode of chain reaction and di...

Fossils are well preserved. 2. The results of comparative analysis of South China Karst Nominated Sites (Phase 1) with similar sites: among the stone forests all over the world, Shilin Stone Forest in Yunnan is neither the tallest nor the oldest one, but the most complicated in the evolution history and richest in the forms. It represented a unique evolvement mechanism of stone forest development; Libo cone karst, possesses not only the most typical karst cones, but also the most complex assemblages of the cone karst.

"中国南方喀斯特"第一批世界自然遗产提名地与相似地点进行对比分析结果：云南石林喀斯特不是最高的石林，也不是最古老的石林，但云南石林形成演化历史最复杂，石柱的形态最丰富，代表一种独特的石林形成演化机制；荔波锥状喀斯特不仅锥峰单体最典型，而且锥状喀斯特地貌组合形态最丰富，代表典型的锥状喀斯特地貌特征，反映出大陆热带–亚热带锥状喀斯特的地质演化模式与过程。

For the former, the binding energy is small and the size is large, with the typical example being the deuteron. For the later, the binding energy is large. d〓 is a typical example, whose binding energy is hundreds of MeV, Even taking into account the theoretical errors, it is still a stable dibaryon candidate.

前者的束缚能较小，半经相对较大，典型代表是氟核d；后者有较深的束缚势阱，最典型的例子是d*，它的束缚能达到数百MeV，即使考虑到理论模型的误差，它仍然可能是紧束缚的双重子态。

We shall, therefore, from the outset drop all claim to general validity for our conclusions, and we shall console ourselves by reflecting that, with the means of investigation at our disposal to-day, we could hardly discover anything that was not typical, if not of a whole class of disorders, at least of a small group of them.

任何要求我们的结论有普遍正确性的主张最后都要放弃，因此，我们用这样的方法来安慰自己，以我们今天处理病例的研究方法，很难发现什么东西不是典型的，即使不是整个一类失常，至少一小组失常也是典型的。

Hairy roots were induced from tobacco leaves with Agrobacterium rhizogenes LBA1334 harboring agropin type PRil855 and binary vector PIG121HM carrying a kanamycin resistant gene nptll and GUS gene and the good hairy root clones were selected. The root with many root hairs and branches grew vigorously toward all the direction on MS medium without plant hormone and on kanamyain containing medium (km:30mg/L). The structure of the hairy root tip is different from that of ordinary root. Witch was not typical root cap maybe the main cause of losing the geotropism of hairy root. Plantlet regenerated from hairy root when cultured on Ms medium without plant hormone. The nicotine content of the hairy root was little higher than that in the natural roots.

本研究通过发根农杆菌工程菌LBA1334(含有野生型pRi1855质粒和pIG121HM双元载体质粒，编码NPTⅡ基因和GUS基因)转化烟草沙姆逊，获得了具有卡那霉素抗性烟草发状根，并筛选出良好的单克隆株系，该发状根具有典型的发状根特性(多根毛、多分支、在无激素培养基上快速生长)，通过根尖压片分析，烟草发状根不具备典型的根冠；发状根中烟碱含量1.61％稍高于与天然栽培品种母体根的含量(1.5％左右)，发状根向培养液中释放烟碱，释放量最多时占总烟碱量的81.1％；在无激素的培养基上获得了再生植株。

Batsch , which have different softening characteristics during maturation and postharvest storage. Of the two cultivars, one was'Hongli'with red flesh clinged to the pit which softened faster after harvest; the other was'Baili'with white flesh clinged to the pit which softened slower than'Hongli'after harvest and could be stored longer.

Batsch中的两个成熟软化特性不同的品系为试材，这两个品系一个是典型的红里桃，即与果核相连的果肉呈红色，成熟后期变软快，采后不耐藏；另一个是典型的白里桃，即与果核相连的果肉无颜色，成熟后期变软慢，采后较耐藏。
