The tail tunnels with sloping ceiling is a new bodily form of pipeline for hydro-power stations. In the specific conditions, it can replace the surge tank of tailrace tunnel .It is applicable specially, if the water lever fluctuates greatly in lower reaches of a river and the length of tailrace tunnel system is between 150m and 600m.

变顶高尾水洞是一种新型的水电站管道体型，它在特定条件下能够取代尾水调压室，尤其适用于下游水位变幅大、尾水系统长度在150—600m之间的情况，从而节省较多的工程量，加快施工进度。

The results indicate that the tailrace tunnel has a good effect on air cooling and dehumidification in summer, and that the parameters of outlet air in the tailrace tunnel are mainly influenced by the temperature of tail water rather than by the parameters of outdoor air and the terminal air parame...

测试结果表明，夏季运行时无压尾水洞对引入空气有良好的降温除湿效果；在无压尾水洞足够长的条件下，尾水洞末端引风参数主要受尾水温度的影响，而受室外空气参数的影响很小，尾水洞出口空气接近对应尾水温度的饱和状态。

In this study,under laboratory conditions,using traditional microbiological culture method,select the Pb2+ stress training of Pistia stratiote and Myriophyllum spicatum L. under water culture, through the changs of root- microbial of Pistia stratiote and Myriophyllum spicatum L.,the results show that bacteria,fungi,actinomycetes have different concentrations under Pb2+ stress. It is specificity of ammonification, nitrification,andanti-Nitrosation after Pb2+ stress.

中文摘要：本研究在实验室条件下，用传统的微生物培养法，选择重金属离子Pb2+在水培条件下对大薸和穗状狐尾藻进行胁迫培养，通过测定大薸和穗状狐尾藻根系的微生物区系及与氮循环有关的四种细菌的数量变化发现：细菌、真菌、放线菌对重金属Pb2+的不同浓度的敏感性不同；重金属Pb2+胁迫对氨化、硝化、亚硝化和反硝化四类细菌的影响也表现出各自的特殊性。

MDA content, cell division , he activities of NR, CAT, POD and SOD of Pistia sagittifolia and Myriophyllum Spicatum with heavy metal,s ion concentration to appear a trend of ascending firstly and desending secondly . This trend explains that Pistia sagittifolia and Myriophyllum Spicatum on the Toxic Effects have similarities under handing the single Pb2+ and Hg2+. As the range of the concentration which each index is arriving at the maximum is different, this also indicates that there are some differences of the Toxic Effects between Pistia sagittifolia and Myriophyllum Spicatum under handing the single Pb2+ and Hg2

丙二醛含量、脂膜透性、硝酸还原酶活性、过氧化物酶活性、超氧化物歧化酶活性、过氧化氢酶活性随重金属离子浓度的增加呈先升后降趋势，说明在单一Pb2+和Hg2+处理下大薸和穗状狐尾藻毒害效应具有相似性；但各指标到达最大值的浓度范围不同，又说明单一Pb2+和Hg2+处理下大薸和穗状狐尾藻毒害效应具有差异性。

The calling and copulation behaviour of Ancylis sativa Liu had a dielperiodicity.The female moths began to calling at the first day and increasedto 100% at the second day,then the percentage of calling decreasedgradually from the third day to the fifth day,only 16.7% of females showingcalling behaviour at the sixth day.The effect of environmentaltemperature on calling behaviour of Ancylis sativa Liu was studied duringadult life at 16℃,21℃,26℃ and 31℃.The result showed differenttemperature during adult life affected significantly the calling behaviour ofvirgin females.There was considerable variability in the calling patternsamong the different temperature groups,the higher the temperature was,thelater females called,the shorter the calling behaviour lasted.The copulationbehaviour of Ancylis sativa Liu can be divided into following squence:female calling,male responsing,male approaching female,hairpencil displayingand copulating.

枣粘虫求偶和交配行为研究结果表明，在光周期为14L：10D、温度为21℃下，越冬代枣粘虫雌蛾的求偶高峰期为黑暗期6.0-8.0小时，求偶活动以羽化后1-3天表现强烈，第二天求偶百分率高达100％，第4天开始，求偶百分率下降，到第6天仅为16.7％；环境温度对枣粘虫雌蛾的求偶活动有明显的影响，随着温度的下降，求偶高峰期明显提前，求偶高峰期的持续时间变长，在21、26、31℃下，求偶百分率接近或达到100％，在16℃下，仅为43％；枣粘虫的交配行为可分为雌蛾求偶、雄蛾反应、雄蛾接近雌蛾、打开味刷及交配成功等阶段；交配活动也以羽化后前3天表现强烈；第1、2代在黑暗周期中的交配高峰期比越冬代推后1-2.5小时；越冬代枣粘虫的交尾持续时间多为3-4小时，第1、2代比越冬代短；越冬代交尾前期多为2-3天，第1、2代多为1-2天，少数羽化当天便可交尾；雌雄成虫均有多次交尾习性，雄蛾最高交尾6次，平均3.3次，雌蛾最多交尾3次，平均1.5次，在田间自然条件下，大多数越冬代雌雄成虫只交尾1次，第1、2代交尾次数有所增高，第1、2代成虫交配率明显高于越冬代。

An adult Macaca fascicularis, or long-tailed macaque, ensconces an infant in her arms in a roadside clearing between coastal Pattaya and Bangkok, Thailand. These primates get their common name from their extraordinarily long tails, which, at 1.3 to 2 feet (40 to 60 centimeters), are usually longer than the macaques are tall.

一只成年的长尾猿或短尾猿，在路边一只幼稚的短尾猿隐藏在它妈**肢体下，位于泰国，曼谷地空旷地和海岸之间，这些灵长类得到它们的普通名字来自它们的格外的长尾，那尾长达40～60厘米较比短尾猿更加长。

The shear layer vortices dominate in the initial portion of the jet, which are a result of the K-H instability. The crossflow encounters an adverse pressure gradient ahead of the jet and separates to form horseshoe vortices under the pressure downstream, and they develop into the wake. The wake vorticity comes into being in the actions of an adverse pressure gradient and a wall-normal component of vorticity, which originates from the wall boundary and is entrained into the jet. The shear layer vortices encounter adverse pressure gradients in the lee of the jet and break down, leading to the formation of the CVP and the CVP is the most important characteristic of the jet in crossflow.

文中指出：剪切层涡源于射流与横流之间的K-H不稳定性；马蹄形涡的产生是由于射流喷口上游迎风侧的壁面边界层内存在逆压梯度，使流动发生了分离，在下游逆压梯度的挤压作用下，形成了马蹄形涡，马蹄形涡向下游发展，进入尾迹区；在逆压梯度和法向涡生成项的共同作用下产生了尾迹涡，尾迹涡源于壁面边界层，止于射流，并将部分涡量向上输运至射流内部的CVP；CVP是横向紊动射流的重要特征，剪切层涡破裂后，在逆压梯度的作用下CVP形成。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
