No shoot, says Friday, no yet, me shoot nom, me no kill; me stay, give you one more laugh; and indeed so he did, as you will see presently; for when the Bear see his Enemy gone, he comes back from the Bough where he stood; but did it mighty leisurely, looking behind him every Step, and coming backward till he got into the Body of the Tree; then with the same hinder End foremost, he came down the Tree, grasping it with his Claws, and moving one Foot at a Time, very leisurely; at this Juncture, and just before he could set his hind Feet upon the Ground, Friday stept up close to him, clapt the Muzzle of his Piece into his Ear, and shot him dead as a Stone.

主人！但他毕竟是个勇敢的男子汉，立即催马冲到向导跟前，拿起手枪，对着那只狼的头上就是一枪，结果了那畜牲的生命。可怜的向导应该说运气不错，因为他碰上了星期五。星期五在他家乡与野兽打惯了交道，所以一点也不害怕。他能坦然地走到狼的跟前，一枪把它打死。要是换了别人，就不敢靠得那么近开枪了。而从远距离开枪，不是打不着狼，就是可能打着人。即使像我这样胆大的人，见此情景也着实吓得心惊肉跳。说实在的，我们一行人都吓得魂不附体，因为，紧跟着星期五的枪声，我们就听见两边的狼群发出一起最凄惨的嚎叫，山谷里又发出阵阵回声，结果狼嚎和回声此起彼伏，犹如成千上万的狼在吼叫。说不定来的狼确实也不止这几只，要不，我们也不至如此惊恐万状了。星期五打死了那只狼之后，另一只本来紧咬着马不放，登时也松了嘴逃跑了。幸亏这只狼咬住了马头，马勒头上的铁圈刚刚卡住了狼的牙齿，因而马没有受什么伤。可是向导的伤可不轻，因为那只激怒了的野兽一共咬了他两口，一口咬在肩膀上，一口咬在他膝头上方。而且，当星期五上前把狼打死时，他那匹受惊的马几乎把他摔了下来。不用说，一听到星期五的枪声，我们立即催马向前。

Active hubs also are called multiport repeaters because they have multiple ports and they regenerate the signal coming into one port before sending it back out the other port.

有源集线器也被称为多端口中继器，因为它们具有多个端口并且将进入一个端口的信号再生法到其他端口上。

When the pressure is low, the role of Poppet head pressure sufficient to overcome the pressure regulator spring force, Poppet Head is closed at this time there is no pressure on the oil through the damping holes on the balance of the piston movement, so a balance piston, the next two cavity pressure equal, balanced piston under the action of the spring force gently on the top of the seat, pressure port and overflow port unreasonable.

当压力较低时，作用在提动头上的压力不足以克服调压弹簧力，提动头处于关闭状态，此时没有压力油通过平衡活塞上的阻尼孔流动，故平衡活塞上、下两腔压力相等，平衡活塞在弹簧力的作用下轻轻地顶在阀座上，压力口和溢流口不通。

Cylinder, the cylinder sets of radial a surplus deformation of the cylinder sets a great impact on the cylinder liner reduced radial a surplus amount to reduce the deformation of the cylinder sets, the top surface of the body decreases roughness, but it will increase the body on the plane cylinder only mouth the roughness ; Preload reduced cylinder head bolt deformation of the cylinder liner little effect, the body can reduce the top surface roughness and cylinder body on the plane I ended roughness; Shen appropriate reduced cylinder head bolt hole deep can reduce the deformation of the cylinder sets, but will cause the body and the top surface roughness on the cylinder body only I roughness increases Plane .

工作工况下，对于第2缸来说，气缸套径向过盈量对气缸套变形影响很大，减小气缸套径向过盈量，有利于减小气缸套的变形，减小机体顶面不平度，但会增大机体上缸套止口平面的不平度；减小缸盖螺栓预紧力对气缸套变形影响很小，可减小机体顶面不平度和机体上缸套止口平面的不平度；适当减小缸盖螺栓沉孔深可以减小气缸套的变形，但会造成机体顶面不平度和机体上缸套止口平面不平度的增大。

The probing behaviors of the tea green leafhopper, Empoasca vitis Gothe, on nine tea cultivars were studied by videotext Direct Current-Electrical Penetration Graph, i. e. DC-EPG. Following seven types of waveforms produced by the leafhopper stylet probing were determined: A, stylet pathway formation; S, salivation when stylets pierce into and stay in phloem; C, active ingestion before stylets reach phloem; E and F, passive ingestion in phloem; R, the insect resting with its stylet inserted into the leaf tissue and NP, not probing.

应用可视DC-EPG方法研究了假眼小绿叶蝉在9个品种茶苗上的口针刺探行为，共发现并初步确定了7种主要波型，即A波、S波、C波、E波、F波和R波、以及非刺探波NP波。A波为刺探波，S波为口针向韧皮部刺探和进入韧皮部中的分泌唾液波，C波为口针到达韧皮部之前的主动取食波，E波和F波为口针在韧皮部中吸收波，R波为取食间歇波。

The results showed that the surface architecture and ultrastructure of gills filaments and secondary gill lamellaes of the largemouth and the blue gill were similar to other teleosts.

结果表明：大口黑鲈和蓝鳃太阳鱼鳃的表面结构和微细结构与其它硬骨鱼类基本相似，鳃弓和鳃耙表面被具环形微嵴的上皮细胞所覆盖，表面观凹凸不平；大口黑鲈鳃耙的尖齿直径和长度分别为蓝鳃太阳鱼鳃耙的3.4~3.8倍和2.1~3.8倍；两种鱼的鳃丝末端略为膨大呈勺状，鳃丝表面都具有规则或不规则分布的环形微峙、沟、坑、孔等结构；大口黑鲈鳃丝之间的距离相对较大，蓝鳃太阳鱼的鳃丝间距离仅为大口黑鲈的83%~88%；大口黑鲈鳃小片的高度、厚度和片间距都大于蓝鳃太阳鱼。

In the gasifying oven, there are coal feeding port and fuel gas feeding port at the top and the bottom, an inclined plane which drops coal grains and accumulates them onto the bottom, and the ventilating duct with opening over the fuel gas feeding port. It has also steam feeding port at the bottom, resultant gas outlet on the side and waste gas outlet at the upper part.

它是在气化炉的上部和底部分别设有煤供给口和燃气供给口，并设有使投入的煤颗粒落下、堆积到底部上的倾斜面，以及开口端在燃气供给口的上方、在炉内朝上延伸的通风管；还在气化炉的下部和侧部分别设置蒸汽供给口和生成气体排出口，并在上部设置废气排出口。
