尾

A clear Matsudaira's Storm-petrel I saw in Taidung in Aug 2004 was uniform mid-pale brown above; noticeably broad-winged; and flew with slow, steady wing action in a direct path (not "charging about" like Swinhoe's).

我2004年8月在台东观察到一只清楚的日本叉尾海燕，看起来是均匀中度灰棕色，有醒目的宽翼，而且以缓慢、稳定的振翅方式朝直线路径前进(不像黑叉尾会不定时转弯， S 型蛇行前进)。

衡水毛笔笔尖选取黄狼尾、香狐尾、南山羊毛、羊须、白马毛、牛耳毛等各种动物毫毛为原料，笔杆采用毛竹、紫竹、斑竹、湘妃竹、凤眼竹等材料，笔杆上嵌装牙、骨、角、竹、硬木等多种样式口顶。

Using this method, alignment between headstock and tailstock centers is not able to be adjusted, and is far from what would be considered "close tolerances." All leadscrews have 1/4-20 threads, with the cross slide and main lead screws being the appropriate left-hand lead, while the tailstock is a right-hand lead, so turning the handwheel always advances the slide away from the user.

使用这种方法，路线之间的 headstock和尾架中心，是无法加以调整，是远远没有到会被认为是&密切公差&的所有leadscrews有1/4-20线程，与两岸幻灯片和主要领导螺丝被适当的左莅带头作用，而尾架是一个右手边的铅，因此，把手始终进展幻灯片远离用户。

First, the theory of fretting wear and studies on fretting fatigue were introduced and the parametric method was used in the process of creating the model of dovetail joints in UG software. The elastic contact problem is analyzed in finite element method and is used to the parameters' distribution and contact stress of the joint are obtained on the base of ANSYS code. With the effect factor of load frequency, the prediction method of fretting fatigue life of dovetail joint under low and high/low cycle complex load is proposed. The proposed model and the approach were verified by experiments.

本文介绍了微动损伤的机理和微动疲劳寿命的研究方法；利用UG软件对燕尾榫联接结构创建了参数化实体模型；基于ANSYS软件平台求解弹性接触问题，获得了榫联接结构接触应力及接触状态量的分布；在已有微动疲劳寿命预测模型的基础上，引入载荷频率影响因子，对低周、高低周复合载荷作用下的燕尾榫联接结构进行了微动疲劳寿命的预测，与试验结果对比表明采用本文提出的方法预测榫联接结构的微动疲劳寿命是有效的。

It is very important to design draft tube because its loss is very great in lower head power plant.

对于低水头电站，尾水管的损失占整个机组损失的很大部分，因此，尾水管的设计十分重要。

The experimental results showed that this dissertation has certain practical importance for qualitatively analyze draft tube pressure fluctuation.

对引起尾水管涡带压力脉动的转轮出口环量计算公式进行了简化，也对描述压力脉动两个主要特征参数频率和振幅的计算公式做了尝试性的简化推导，并且通过实例计算说明，本文所做的尝试性的工作，为定性分析尾水管涡带压力脉动特性有一定的实用价值。

The result clearly reappearances vortex movement at the part load condition and flow field and pressure distribution in the draft tube under different conditions,which were much more rational and similar to practical experiment results,and which assure that the inlet velocity model is very close to the authenticity.

计算结果后处理清晰再现了小流量工况尾水管涡带的运动形式和三种工况下尾水管内部的流场和压力分布，情况和实际符合较好，验证了所建立的进口速度模型的逼近真实性。

且意蜂雄蜂追逐中蜂处女王并试图与其交尾，这种行为对中蜂雄蜂与中蜂处女王的交尾造成了干扰。

The parameters of pulse combustor such asfrequency,length of feed tube drying tube effecting on drying property were analyzed.It ispropitious to dry high surface-water containing,small granule or liquid materials.

分析了脉动燃烧器频率、热负荷、干燥管长等参数对干燥性能的影响；发现脉动燃烧器尾管内干燥更适合于含表面水高的小颗粒物料或液体物料，可充分利用脉动气流和声波能的作用，使物料分散雾化，增大表面积，提高干燥效率；研究了脉动燃烧器尾管内干燥颗粒物料的传热特性，并将试验结果与其它类型的干燥器进行了比较。

Two B-29 style remote control barbettes and a tail gunner's station, each with paired Nudelman-Rikhter NR-23 guns were retained, including the PRS-1 Bee Hind tail gun radar.

两架B - 29式远程控制barbettes和尾炮手的车站，每个配对nudelman - rikhter正- 23枪被保留，包括公共无线电通讯服务- 1蜜蜂后肢尾炮雷达。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
