While the tissue spaces surrounding a few blood vessels wasAl and Fg positive,no Al or Fg positive cells were observed.In antemortem injurygroup,diffuse subarachnoid hemorrhage,cerebral edema,swelling or pyknotic neu-rons could be observed.The axons showed irregular swelling and disconnection at1~3h,marked swelling and disconnection at 6h,and retraction ball at 15h whichwas more remarkable at 24h after injury.The space between myelin sheaths andaxons was increased at 3~6h after injury.Tortuous and wavelike myelin sheathswhich adhered on axons incompletely,or even peeled off could be found from 15hto 24h after injury.Perinuclear lysis of Nissl bodies began at 24h after injury.Thenumber of GFAP positive cells in cerebrum and brain-stem increased significantlyfollowed by decrease,and then increased again,but the time courses of the changesin different areas of brain were not same.Al and Fg positive neural cells,mainlysurrounded blood vessels,with diffuse or peripherally distributed positive matter incytoplasm could be observed at 0.5h after injury.The number of Al or Fg positivecells and the intensity of immunoreaction increased with the time of injury.The areaof SYN positivity in medulla oblongata and pons decreased notably 3~6h afterinjury,then return to normal levels and continued to 24h after injury.

生前损伤组,可见广泛蛛网膜下腔出血,脑组织水肿,神经细胞肿胀,晚期神经元固缩;伤后1~3h见部分神经轴突不规则增粗、断裂,伤后6h断端膨大,伤后15h可见收缩球,至伤后24h更为明显;伤后3~6h可见部分神经髓鞘与轴突之间的间隙增宽,伤后15h髓鞘明显曲折,不完全附着在轴突两侧,甚至剥脱,持续到伤后24h;核周尼氏体减少在伤后24h才开始出现;同一部位的GFAP阳性细胞数目随损伤时间发生改变,先增多(最早在伤后0.5h),达到高峰后减少,其后又有增多趋势,但不同部位的GFAP阳性细胞数目增减的时间过程不尽相同,同时,大脑中的GFAP阳性细胞数目也有改变;伤后0.5h,可在脑干组织中见到Al和Fg阳性神经细胞,主要位于血管周围,阳性物在胞浆中呈弥散性分布,但部分细胞的阳性物仅分布于靠近胞膜的胞浆中而呈环状,随损伤时间延长,阳性细胞数目增多,反应强度增加;伤后3~6h,延髓及桥脑中的SYN阳性物面积减少,其后恢复到正常水平,并持续到伤后24h。

This is a question of courtesy and consideration,as the reimportation of goods into a country will involve customs entries and other formalities,to say nothing of the actual cost of freight and insurance.

买方有权回到卖方任何商品,但他们却没有秩序,但在出口贸易通常是由买方先找出卖方'wishes在这件事这是一种礼貌和考虑,为reimportation货物到一个国家将涉及海关条目和其他手续,更不用说实际成本运费和保险费它也有可能是错交货可能被用于另一个客户在同一个国家的接收器,所以货物发送到正确的地址最好让卖方指导自己的航运和货运代理出席,尽管他们在全国分公司或记者的买主,而非积极参加在货物发送的麻烦。

As the same section is concerned, near the bottom the maximum value of frequency appear within 1mm of bubble size, towards the water face this value tend to decrease, yet the corresponding size turns to increase; in the same time, the frequency is concentrated near the bottom and deconcentrated near the water face; under the experiment condition, the maximum frequency of the total section approximately appear at 0.5mm size; mean bubble size access 0 at bottom and increase acceleratively towards water face where tend to be infinite; total number increase during developing of aeration, and become steady when reach wholly developed area; on the same section, the total number in unit time tend to increase at first and decrease then, along the water depth.

对于同一断面,靠近槽底的测点气泡个数分布最大值出现在气泡尺寸小于1mm的范围内,朝水面方向各测点气泡个数分布最大值呈减小趋势,而其对应尺寸则呈现变大趋势;在靠近槽底,个数分布表现得比较集中,而在水面附近气泡个数分布曲线表现得低而平缓;实验条件下,整个断面上的气泡个数分布的最大值大体上出现在尺寸为0.5mm的地方;气泡平均尺寸在槽底处接近于0而朝水面方向迅速增大,且越接近掺气水流的水面,增加速度越快,最终趋于无穷大;气泡总数在掺气发展区内是沿程增加的,当掺气水流发展到一定程度后气泡总数就基本保持不变了;在同一断面上,各测点单位时间内的气泡总数随高度呈现出先增加后减小的趋势。

The rainy Season was in the mean Time upon me, when I kept more within Doors than at other Times; so I had stow'd our new Vessel as secure as we could, bringing her up into the Creek, where as I said, in the Beginning I landed my Rafts from the Ship, and haling her up to the Shore, at high Water mark, I made my Man Friday dig a little Dock, just big enough to hold her, and just deep enough to give her Water enough to fleet in; and then when the Tide was out, we made a strong Dam cross the End of it, to keep the Water out; and so she lay dry, as to the Tide from the Sea; and to keep the Rain off, we laid a great many Boughs of Trees, so thick, that she was as well thatch'd as a House; and thus we waited for the Month of November and December, in which I design'd to make my Adventure.

雨季快到了,那时我们大部分时间都只好呆在家里,为此,我得先把我们的新船放置妥当。我把船移到从前卸木排的那条小河里,并趁涨潮时把它拖到岸上。我又叫星期五在那里挖了一个小小的船坞,宽度刚好能容得下小船,深度刚好在把水放进来后能把船浮起来。然后,趁退潮后,我们又在船坞口筑了一道坚固的堤坝挡住海水。这样,即使潮水上涨,也不会浸没小船。为了遮住雨水,我们又在船上面放了许多树枝,密密层层地堆了好几层,看上去像个茅草屋的屋顶。就这样,我们等候着十一月和十二月的到来:那是我准备冒险的日期。

When I see on the one side the inert bank —— for the sun acts on one side first —— and on the other this luxuriant foliage, the creation of an hour, I am affected as if in a peculiar sense I stood in the laboratory of the Artist who made the world and me —— had come to where he was still at work,sporting on this bank, and with excess of energy strewing his fresh designs about.

当我在路基的一面,因为太阳是先照射在一面的,看到的是一个毫无生气的斜面,而另外的一面上,我却看到了如此华丽的枝叶,它只是一小时的创造,我深深地被感动了,仿佛在一种特别的意义上来说,我是站在这个创造了世界和自己的大艺术家的画室中,——跑到他正在继续工作的地点去,他在这路基上嬉戏,以过多的精力到处画下了他的新颖的图案。

Wire electrode based on the trajectory of the different forms of control, WEDM can be divided into three types: one is shaped by the imitation controlled cutting in line in advance and work to create the same shape by mold, when processing the workpiece at the same time rough and on the mold clamping in the machine tool table, in the process of cutting wire electrode tightly against the mold on the edge of the track for the mobile, thus cutting out and die on the same shape and precision to the workpiece; another One is the electro-optical tracking control, to carry out the cutting line, before the basis of certain parts to enlarge the proportion of drawings depicts an electro-optical tracking map-processing machines will be placed in design stage of electro-optical tracking, tracking platform Photoelectric first line of graphics has always been to follow the track of the Mexican campaign, and then through the use of electrical, mechanical linkage to control the machine tool table, together with the workpiece so相似形wire electrode relative movement, thus cutting out the same shape and design to the workpiece; again a digital control, the use of advanced automatic control of digital technology-driven machine tool in accordance with the pre-processing parameters according to the workpiece geometry pre-processing procedures for the preparation of a good CNC auto-complete processing, the production does not require appearance on board the need to map to enlarge map of the previous two form of control has a higher machining accuracy and a broad range of applications, both at home and abroad more than 95% have adopted WEDM NC.

根据对电极丝运动轨迹的控制形式不同,电火花线切割机床又可分为三种:一种是靠模仿形控制,其在进行线切割加工前,预先制造出与工件形状相同的靠模,加工时把工件毛坯和靠模同时装夹在机床工作台上,在切割过程中电极丝紧紧地贴着靠模边缘作轨迹移动,从而切割出与靠模形状和精度相同的工件来;另一种是光电跟踪控制,其在进行线切割加工前,先根据零件图样按一定放大比例描绘出一张光电跟踪图,加工时将图样置于机床的光电跟踪台上,跟踪台上的光电头始终追随墨线图形的轨迹运动,再借助于电气、机械的联动,控制机床工作台连同工件相对电极丝做相似形的运动,从而切割出与图样形状相同的工件来;再一种是数字程序控制,采用先进的数字化自动控制技术,驱动机床按照加工前根据工件几何形状参数预先编制好的数控加工程序自动完成加工,不需要制作靠模样板也无需绘制放大图,比前面两种控制形式具有更高的加工精度和广阔的应用范围,目前国内外95%以上的电火花线切割机床都已采用数控化。切割属电加工范畴,是由前苏联人发明的,我国是第一个用于工业生产的国家,当时由复但大学和苏州长风机械厂合作生产的这是最早的机型叫复旦型,我们国内在此基础上发展了快走丝系统。欧美和日本发展了慢走系统LS

The results show that the zinc coating is eroded mostly, and some red rust and black rust appear on the substrate in the environment of oxygen supplied intermittently.

结果表明:在间歇通O2的情况下,锌层大部分被腐蚀,而且在基体上有一些红锈和黑锈产生,镀锌板表面的腐蚀产物呈现着不均匀的针状物;而在间歇通N2时,镀锌板的锌层脱落面积较少,基体上没有产生红锈,腐蚀产物呈大块状;在间歇通O2和通N2的情况下,镀锌板的腐蚀速率先增后降,在200 h时,前者的腐蚀质量损失速率是后者的2倍左右;镀锌板附着库尔勒泥浆时的腐蚀过程受氧去极化过程控制。
