When oversubscription happens, underwriters can reduce the level of discount and increase the bottom price by strategic allocation so that both financing cost and IPO underpricing will be less. It suggests that financial supervisor should allow underwriter to allocate IPO stocks freely to a certain extent in China.3. If independent IPO allocation is allowed in IPO bookbuilding, the underwriter and affiliated institutional investor maybe exploit free allocation and information asymmetry to manipulate.

在发生超额认购时，承销商通过有策略地分配股票可以有效地降低折价水平并保证较高的发行底价，减少了发行成本的同时也减轻了IPO抑价程度，建议我国监管当局可以考虑在适当的时候赋予承销商一定的新股自主分配权。3、在有自主分配权的条件下也可能会发生承销商与关联机构投资者共同进行市场操纵的行为。

因此，在有一定钻井资料的条件下，通过采用大地电磁、地震资料开展有约束的联合反演，可以比较可靠地识别确定该目的层，为该区的海相中、古生界构造研究提供重要依据，以指导该区的油气勘探。

Experiment on photosensitivity characteristics of the samples preformed both at room and high temperature (410℃), respectively.

对薄膜在室温和较高温度(410℃)下进行光敏特性测试，结果表明，薄膜的制备工艺参量对其光敏特性有较大影响；较高温度下其敏感特性和室温下测试的结果大体一致；在合适条件下制备的薄膜对不同波长的光有较好的敏感特性。

Gentleman orchid drenchs rot the root dies after water, the likelihood has the reason of two respects, it is basin earth too wet, because gentleman Lan Xihuan is loose,understand the edaphic requirement that appear, once basin earth is medium moisture is too big, its bulky flesh pledges the root arrived to will come in October between November, already entered stop to grow or grow very slow condition, do not need how many moisture, need to hold basin ground only wet can, drench water causes those who rot the root is unavoidable too much; 2 it is you drench when water, flow into the phyllome center of plant the dirt that will have smudgy part along with all the others, and at this moment water of blade rising bad news is less, sewage accumulating is inside Xie Cong, also can choose sodden heart sodden root.

君子兰淋水后烂根死亡，可能有两个方面的原因，一是盆土过湿，因君子兰喜欢疏松通透的土壤条件，一旦盆土中水分过大，其粗大的肉质根到了10月至11月间，已进入停止生长或生长很慢的状态，不需要多少水分，只需要保持盆土湿润即可，淋水过多造成烂根是在所难免的；二是你淋水时，将会有脏污成分的尘土等一并流入植株的叶丛中心，而这时叶片蒸腾耗水较少，脏水积在叶丛内，也会选成烂心烂根。

Formulates a school platoon class plan is an item consumes extremely when also the quite laborious work, moreover it also must by have the school row of class work experience or this aspect knowledge talented person can complete.

制定一个学校的排课计划是一项非常耗时且相当辛苦的工作，而且它还得由有学校排课工作经验或者这方面知识的人才能做好在一所高校时一个课程表的制定是一个难题，因为在有关课程表的问题上有很多的限制条件得考虑，还有大量的数据空间被挖掘，即便你的输入数据量并不是实际意义上的大批量

The peak forest---the precipitous mountains along the Jumahe river display clearly prismatic peaks, some are pagoda-like, some are platy and having heaven windows which represents the sub-arid climate surface karst landscape typical for North China.

峰丛——拒马河两岸的陡峻高山，有棱角分明的山峰，有塔形山峰，还有板状山形及天窗等，它们代表了我国北方半干旱气候条件下地表岩溶地貌。

The assumption of the variable tendency of slip-line in active zone is made based on the numerical results. Combining the slip-line equations and boundaries, the formula of bearing capacity is deduced which can consider the density of soil. The formula of bearing capacity of strip footing on ponderable soil is also deduced assuming that the slip-line field of ponderable soil is the same with that of weightless soil, which is proved to be an upper-limit solution, as its the same with that deduced by the upper-limit method in Prandtl mechanism.

在数值计算结果的基础上，对有重土地基主动区滑移线变化趋势进行了合理假设，根据边界条件和特征线方程求得了条形基础极限承载力的解析表达式，该表达式可以计算考虑土重度的条形基础的极限承载力；获得了不考虑重度对滑移线场影响时(即有重土在普朗特尔滑移线场下)极限承载力的解析表达式，该表达式与普朗特尔机动场对应的极限承载力上限解的表达式相同，这就从理论上证明了在土重度对滑移线场没有影响这一假定前提下得到的极限承载力是一个上限；(3)利用上限定理求解了极限承载力的最小上限。

The correlatability between BIF and its wall rocks in the primitive mantlenormalized incompatible element spider diagrams suggests that they have the same or similar material source and diagenetic environment, as well as belonging to a same depositional basin, but with different deposition processes and conditions, respectively.

BIF与其围岩在原始地幔标准化不相容元素蛛网图中的相关性说明二者有相同或相似的物质来源和成岩环境，二者同属一个沉积盆地，但却有不同的沉积过程和形成条件。
