Shutdown, removed the row fan, fan struck by hand, the sense of rotation of the fan is very flexible, so use flat screwdriver inserted under the roots of the gap fanleaf bend to the will of the fan and fan-Block separation and jumped over the fan, the fan to see in the center of a small arc with several magnet surrounded a round shield-shaped, it is clear that this is the fan motor rotor, while the stator is fixed together with the fan-Block a micro-winding, if the fan and fan blocks together, the micro-coil is inserted to the internal rotor.

关机，将该排风扇拆下，用手拨动扇叶时，感觉扇叶的转动很不灵活，故用平头起子插入扇叶根部底下的缝隙内向上翘，将整个扇叶与扇座分离，翻过扇叶时，看到在扇叶的中心部位有一个用数条小弧形磁铁围成的圆罩形，显然，这就是该风扇电机的转子，而定子是与扇座固定在一起的一个微型绕组，若将扇叶与扇座组合在一起，则该微型绕组正好能插在转子的内部。

The first person who appeared upon the steep stone steps was a boy in corduroy trousers and a dark linen smock-frock, who shambled down the stairs with a good deal of unnecessary clatter of his hobnailed shoes, and who was red in the face from the exertion of blowing the bellows of the old organ.

首先出现在很陡的石级上的，是一个男孩，他穿着灯芯绒裤子和黑色亚麻布长罩衫，拖拖沓沓地走下石级时，钉着平头钉的靴子弄出了很多不必要的喀啦喀啦的声音，他刚才使劲儿吹管风琴的风箱，脸还涨得通红哩。

A theoretical analysis of local damage in a thin ductile tube hit by a flat-nosed missile laterally is developed to predict local failure due to plugging by the beam-on-foundation model. The effect of internal press was considered, and differential equations was obtained which can predict the ballistic speed of the missile which impact the tube filled with water. It can be solved by Runge-Kutta method.

采用地基梁模型对平头弹体侧向冲击钢管的冲塞型破坏模式进行了理论分析，考虑了充压情形下内压的影响，导出了钢管在冲击过程中的运动方程，可以用龙格—库塔法进行数值求解来确定弹体冲击充液压力管道的弹道极限速度。

The flow-field around a hemisphere and a flat-nosed cylinder in the shock tube is simulated numerically by using non-equilibrium Navier-Stokes equations with an air chemical model of 5 species 17 reactions, and the catalytic rate constant of surface materials such as Pt, SIC:, Ni and a flight vehicle materials is determined by using the heat transfer rate of testing in the shock tube and the distribution of heat transfer rate along with the catalytic rate constants.

用5组分17个化学反应Durm-Kang空气化学模型和轴对称热化学非平衡Navier-Stokes方程，对激波管中球头和平头圆柱模型绕流流场进行了数值模拟，给出了驻点热流随催化速率常数变化的分布，并根据激波管实验测量的热流值确定了表面材料Pt、SiO2、Ni和某种飞船材料的催化速率常数，建立了数值分析高焓流动边界层催化特性的软件。

Any one who had chanced to pass through the little town of Vernon at this epoch, who had happened to walk across that fine monumental bridge, which will soon be succeeded, let us hope, by some hideous iron cable bridge, might have observed, had he dropped his eyes over the parapet, a man about fifty years of age wearing a leather cap, trousers a waistcoat of coarse gray cloth, to which something yellow which had been a red ribbon, was sewn, shod with wooden sabots, tanned by the sun, his face nearly black his hair nearly white, a large scar on his forehead which ran down upon his cheek, bowed, bent, prematurely aged, who walked nearly every day, hoe sickle in hand, in one of those compartments surrounded by walls which abut on the bridge, border the left bank of the Seine like a chain of terraces, charming enclosures full of flowers of which one could say, were they dddtt.com larger:"these are gardens," were they a little smaller:"these are bouquets."

当年如果8 tt t8.com 有人经过 ssbbww 小城韦尔农，走到那座宏大壮丽的石桥上去游玩（那座桥也许 ssbbww.Com 不久将被一道丑恶不堪的铁索桥所替代），立在桥栏边往下望去，便会看到一个五十左右的男子，戴一顶鸭舌帽，穿一身粗呢褂裤，衣衿上缝着一条泛黄的红丝带，脚上穿的是木鞋，他皮肤焦黄，脸黝黑，头发花白，一条又阔又长的刀痕从额头直到脸颊，弯腰，曲背，未老先衰，几乎整天拿着一把平头铲和一把修枝刀在一个小院里踱来踱去。在塞纳河左岸桥头一带，全是那种院子，每一个都有墙隔开，顺着河边排列，象一长条土台，全都种满花木，非常悦目，如果8 tt t8.com 园子再大一点，就可以 www.ssbbww.com 叫做花园，再小一点，那就是 www.8ttt8.com 花畦了。

Cleancut, crew-cut, wearing white collars even in space, the astronauts had been built up in the public mind as supermen, but as Tom Wolfe's book and Phil Kaufman's movie " The Right Stuff " revealed, they were more likely to be hot-shot test pilots (with the exception of John Glenn) than straight arrows.

。棱角分明，平头，穿一件白领衫，甚至在太空，宇航员在公众面前都被塑造成超人，但正如在汤姆。沃尔夫的书里和菲尔。考夫曼的电影&太空英雄&中所描写的，他们更像英勇的实验飞行员而不是一板一眼的傀儡。

The experimental investigation demonstratesthat (1) the critical perforation energy of pressure pipelines (D/H=15) with pressure OMPa under lateral impact of flat-nose and spherical-nose indenters ranges from 2~3%,the critical perforation energy of empty pipelines is higher 1 ~2% than pipelines filled in water without pressure.

实验研究结果表明：(1)当管梁内注满水，预加工作内压P=0MPa时，对于径厚比D／H=15的厚壁圆管，在平头弹体和球形弹体两种弹体冲击作用下临界穿透破坏能量的降幅在2～3％之间：锥头弹体冲击厚壁空管的临界穿透能量比充水预加内压为P=0MPa的圆管高1～2％：(2)充水管道的预加内压提高，临界穿透能量有一定降低。

Maize inbreds belonging to 3 maize heterotic groups including Reid, Tangsipingtou and compound germplasm were studied to determine the influence of genotypes, media and plant regulators on the embryo-derived calius induction and green plant regeneration. Immature embryos (1.0~2.0 mm) from selfed ears were harvested as explants. Callus could be induced from all the tested inbreds. However, plant regeneration was only obtained in 12 genotypes.

以Reid、唐四平头和其它种质等3个杂种优势类群共19份玉米自交系为试验材料，以玉米幼胚作为外植体，研究了基因型、培养基和激素对玉米幼胚愈伤组织的诱导及植株再生的影响，结果表明供试材料均能进行愈伤组织的诱导，但是仅有12个自交系能再生植株。N6和改良N6培养基有助于提高愈伤组织的质量及其生长速度。2，4-D在愈伤组织的诱导中起着关键性作用。

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。
