If the vertex set of a graph can be partitioned into two disjoint nonempty sets V_(1) and V_(2), every vertex in V_(1) connects every vertex in V_(2) and there is no edge in V_(1) and V_(2), then we call this graph is a complete bipartite graph. If V_(1) contains m elements and V_(2) contains n elements, then we denote this complete bipartite graph K_.

当一个图中的点集合可以分成两个非空的集合V_(1)及V_(2)，若 V_(1)中的每一点都与V_(2)中的点有边相连，且在V_(1)及V_(2)中的点都没有边相连，则称此图为完全二分图；若 V_(1)中有m个点，V_(2)中有n个点，则此完全二分图记为K_。

In conclusion, the lag phase of Streptococcus thermophilus was shorten in the eutrophy culture medium, and the time achieving the culminated point of logarithmic phase was shorted also, at the same time, the stationary phase lengthened. After secondary culture, Streptococcus thermophilus reached directly the log phase hardly through the lag phase, and then quickly reached the decline phase. There were more relations of the metabolic regalities of the three kinds of nutritive substances with the super-concentrated incubation process of Streptococcus thermophilus: the more the number of the bacteria, the quicker the metaboling, while the fewer, the slower the metabolism. Moreover, there apparently existed morphologic changes in this course, and there maybe existed the apoptosis, which correlated with bacteria propagation and acid producing. With the culture time postponed, the nutritive substances in the culture medium lacked also, and the morphologic change and apoptosis appeared more obviously.

结果表明，嗜热链球菌在营养丰富的培养基中的生长延滞期缩短，到达对数生长顶点的时间变短，稳定期的时间延长，当经过二次培养后，嗜热链球菌几乎不经过延滞期直接到达对数期，平稳期持续的时间较短，很快到达衰亡期；嗜热链球菌在超浓缩培养过程中三大营养物质的代谢规律也同它的培养过程有很大的关系，菌数多，其代谢旺盛，菌数降低其代谢速度减慢；嗜热链球菌在超浓缩培养过程中存在着明显的菌体形态变化，并可能存在着细胞凋亡，与菌体增殖和产酸规律密切相关，随着培养时间延长，培养基中营养物质变得贫乏，菌体形态变化和细胞凋亡的情况愈加明显。

A Little Boy How I never could be tired with roaming about that huge mansion, with its vast empty rooms, with their worn-out hangings, fluttering tapestry, and carved oaken panels, with the gilding almost rubbed out---sometimes in the spacious old-fashioned gardens, which I had almost to myself, unless when now and then a solitary gardening man would cross me---and how the nectarines and peaches hung upon the walls, without my ever offering to pluck them, because they were forbidden fruit, unless now and then,---and because I had more pleasure in strolling about among the old melancholy-looking yew-trees, or the firs, and picking up the red berries, and the fir-apples, which were good for nothing but to look at ---or in lying about upon the fresh grass, with all the fine garden smells around me---or basking in the orangery, till I could almost fancy myself ripening too along with the oranges and the limes in that grateful warmth-or in watching the dace that darted to and Fro in the fish-pond, at the bottom of the garden, with here and there a great sulky pike hanging midway down the water in silent state, as if it mocked at their impertinent friskiness,---I had more pleasure in these busy-idle diversions than in all the sweet flavors of peaches, nectarines, oranges, and such like common baits of children.

The results of the ultrastructares of the glandular hairs show that there are a number of the plastids in which there are a big of osmiophilic substances in the secretory cells of the peltate hairs and then that there are much endoplasmic reticulum in the secretory cells of head hairs. The difference between them are with relation to the function.

腺毛超微结构观察的结果表明，盾状腺毛类分泌细胞的优势细胞器是质体，其中具大量的嗜锇物质；而头状腺毛类分泌细胞的优势细胞器是内质网，这种细胞器上的差异与头状腺毛和盾状腺毛的分泌功能是相适应的。

There were no statistically differences between the 8th~ 14thday, the 15th - 21th day post-BC and the control group. During the rt~24tkday post-BC , pycnosis degeneration or necrosis neurons of the locus cerebral cortex, dorsal hippocampus, dentate fornix were significantly increased, then decreased gradually, but recovered to normal by the 24thday after BC, and especially in parietal cortex and piriform cortex the necrosis neurons were significantly increased than temporal cortex , and there were no statistically difference berween the left and the right side. Pycnosis degeneration or necrosis neurons in the brainstem reticular formation were markedly increased in the 4thday after BC, and there were no statistically difference among the other groups and the control group.

与对照组相比，BC后在大脑皮质、背侧海马和齿状回部位，固缩变性和不完全坏死细胞数先显著增加(P＜0.05)，然后逐渐减少，至24d基本恢复正常；顶叶、梨状皮质比颞叶皮质变性坏死细胞多，差异有高度显著性(P＜0.01)；大脑左侧比右侧变性坏死细胞稍少但差异无显著性；在BC后4d，脑桥核、斜方体核平面的脑干网状结构中固缩变性和不完全坏死细胞数明显增多(P＜0.05)，其它组间无显著性差异。

The red star TV factory ,which produces TV sets of fine quality ,was set up in the 1980's ,there were only a little more than 2000 workers then ,and most of them were junior middle school graduates ,the working conditions were poor ,there were only three workship with some simple equipment ,the main products then were black and white TV sets

Boppin:while there are decent boppers today, the skill level was higher then, and back then the dance seem to fit the era much better, and the boppers were even more effective then.

boppin方面：现在的boppers很正派，得体。技术水平比过去高！舞蹈变得更符合这个时代了，更具有感染力了！

Reefs, reef-mounds and lime mud mounds are all carbonate buildups, and the reefs and banks are important targets for petroleum exploration The reefs, banks and mounds should be divided from each other not only in theory, but also in exploration practice, because of so many differences in sedimentary compositions, fabrics, environments, distribution in time and space, and the characteristics of petroleum geology If the original reef or bank itself was fine reservoir rocks, then it would become a better reservoir after the reservoirconstructive diagenesis The formation of a high quality carbonate reservoir is controlled by two factors: the sedimentary microfacies and the reservoirconstructive diagenesis The first is the basis for the formation of a high quality reservoir, and with the high energy reefbank facies as the best; the latter includes the cataclasis, the dolomitization and the karstification The dolomitization and karstification are the best for the formation of a high quality reservoir The karstification has the widest distribution, profoundest effect, and plays a vital role in the high quality reservoir forming The karst types are quite rich in the limestone reef or bank reservoir, including synsedimentary karst, penesedimentary karst, supergene karst and hydrothermal karst, and so does the dolomitization reef or bank reservoir The formation mechanism of synsedimentary karst and penesedimentary karst is related to the short time exposing and leaching of the cyclical highfrequency shallowupward sequence when the reefs or banks are forming The supergene karst is controlled by the exposing and leaching of tertiary cyclic sequence type I interface after the reefs or banks forming Thus, there developed a great deal of secondary corrosion pores, corrosion fractures and huge caves besides some original pores remained in the reef and bank reservoir Scarcely there are any original effective pores in reefmounds and lime mud mounds, especially in senkes among mounds, but secondary pores could be formed by karstification, and there would likely develop source rocks with high organic abundance

礁、礁丘、丘同属碳酸盐建隆，礁、滩是重要勘探目的层。但各自在沉积组分、组构、环境和时空分布，以及油气地质条件上迥然不同，因而无论从理论还是勘探实践上，都有必要将其各成体系划分开来。礁滩自身为好储集岩，当建设性成岩作用叠加后可形成好的储层。碳酸盐岩优质储层形成，主要受沉积微相与建设性成岩作用两大因素控制。前者是基础，并以高能的礁滩相带为最好；后者主要包括破裂、白云石化和溶蚀三大类，并以白云石化或溶蚀为最优，其中的溶蚀分布最广泛、影响最深刻而对优质储层形成起决定性作用。礁滩储层中的古岩溶类型最为丰富多彩，包括同生期、准同生期、表生期和埋藏期热流体岩溶的所有类型，白云岩化礁滩体也不例外。其中，同生准同生期岩溶的形成机制与礁滩沉积时高频层序旋回向上变浅序列的短暂暴露淋溶有关，表生期岩溶则受控于礁滩沉积后三级层序旋回Ⅰ型界面的暴露淋溶。由此，导致礁滩储层中除了可以也是唯一保存原生孔隙外，还发育了次生溶蚀孔洞缝和大型溶洞。礁丘、灰泥丘尤其是丘间洼地中发育高有机质丰度烃源岩；它们自身没有有效的原生孔隙，但岩溶作用可以形成次生孔隙。

Well here it is first u have to roll at a moderate speed than you take the back foot off your board and just like the boneless u have to start lifting your board up and when you reach about your knee level u have to put your left ora right hand you start power lifting your body up to the air and before u do that u have to lift up your needs to your chest and then from there you have to push your legs out and stay there as much and you can and try to put as much pressure on your arms as you can and extend your body before you come down and if u have to bail then this is the right time and make sure when you bail that you roll.

以适速前进然后后脚下来像boneless一样，用前手把板抬起到膝盖高度时用你惯用的那只手撑地有力地把你的身体撑起到空中，在这之前你已经把膝盖靠到胸部了，然后伸膝保持时间尽可能长，并把主要的压力放到手上，在下来前伸展身体，如果要摔时，在这个时候最好，身体缩成团滚开。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.
