The presence of REE tetrad effects in apatites and whole rocks of S-type granites has been reported by Sha and Chappell (1999) and Zhao et al.(1999), respectively. The REE tetrad effect in minerals, such as apatite, spessartite, beryl, alkali feldspar and spodumene, from all zones of Altay No. 3 pegmatite has been found remarkable, and the fractionations among isovalent incompatible elements in these minerals are also significant. This paper puts forward that the REE tetrad effect is one of the basic features of peraluminous melts and the origin of REE tetrad effect might be probably related to some processes prior to the formation of pegmatite magma. The immiscibile liquid separation between silicate melt and hydrosaline melt may be responsible for it.

由于阿尔泰3号伟晶岩脉各带磷灰石以及与其共生的石榴石、绿柱石、碱性长石、锂辉石矿物均存在明显的稀土"四重效应"以及相同电价、相似离子半径的不相容元素间存在显著的分异，并结合最近赵振华等(1999)和Sha and Chappell(1999)报道S型花岗岩全岩和单矿物(磷灰石、独居石、长石、黄玉等)均存在稀土"四重效应"这一现象，本文研究提出，稀土"四重效应"是富挥发分过铝质岩浆体系的一个基本特征，其机制既不可能由含稀土的副矿物早期结晶引起残余熔体相中REE含量变化的结果，也不能定性地归因于流体相与熔体相相互作用过程中稀土元素在流体/熔体之间分异的结果，而很可能与伟晶岩岩浆形成之前某些过程密切相关，S型花岗岩岩浆在液相线以上存在硅酸盐熔体与高盐熔体的不混溶液相分离有可能是过铝质岩浆体系产生稀土"四重效应"的主要原因。

The battle once begun, its very various changes,--the resistance of Hougomont; the tenacity of La Haie-Sainte; the killing of Bauduin; the disabling of Foy; the unexpected wall against which Soye's brigade was shattered; Guilleminot's fatal heedlessness when he had neither petard nor powder sacks; the miring of the batteries; the fifteen unescorted pieces overwhelmed in a hollow way by Uxbridge; the small effect of the bombs falling in the English lines, and there embedding themselves in the rain-soaked soil, and only succeeding in producing volcanoes of mud, so that the canister was turned into a splash; the uselessness of Pire's demonstration on Braine-l'Alleud; all that cavalry, fifteen squadrons, almost exterminated; the right wing of the English badly alarmed, the left wing badly cut into; Ney's strange mistake in massing, instead of echelonning the four divisions of the first corps; men delivered over to grape-shot, arranged in ranks twenty-seven deep and with a frontage of two hundred; the frightful holes made in these masses by the cannon-balls; attacking columns disorganized; the side-battery suddenly unmasked on their flank; Bourgeois, Donzelot, and Durutte compromised; Quiot repulsed; Lieutenant Vieux, that Hercules graduated at the Polytechnic School, wounded at the moment when he was beating in with an axe the door of La Haie-Sainte under the downright fire of the English barricade which barred the angle of the road from Genappe to Brussels; Marcognet's division caught between the infantry and the cavalry, shot down at the very muzzle of the guns amid the grain by Best and Pack, put to the sword by Ponsonby; his battery of seven pieces spiked; the Prince of Saxe-Weimar holding and guarding, in spite of the Comte d'Erlon, both Frischemont and Smohain; the flag of the 105th taken, the flag of the 45th captured; that black Prussian hussar stopped by runners of the flying column of three hundred light cavalry on the scout between Wavre and Plancenoit; the alarming things that had been said by prisoners; Grouchy's delay; fifteen hundred men killed in the orchard of Hougomont in less than an hour; eighteen hundred men overthrown in a still shorter time about La Haie-Sainte,--all these stormy incidents passing like the clouds of battle before Napoleon, had hardly troubled his gaze and had not overshadowed that face of imperial certainty.

交锋以后，战争的非常复杂惊险的变化，乌古蒙的阻力，圣拉埃的顽抗，博丹的阵亡，富瓦战斗能力的丧失，使索亚旅部受到创伤的那道意外的墙，无弹无药的吉埃米诺的那种见死不退的顽强，炮队的陷入泥淖，被阿克斯布里吉击溃在一条凹路里的那十五尊无人护卫的炮，炸弹落入英军防线效果不大，土被雨水浸透了，炸弹陷入，只能喷出一些泥土，以致开花弹全变成了烂泥泡，比雷在布兰拉勒出击无功，十五营骑兵几乎全部覆没，英军右翼应战的镇静，左翼防守的周密，内伊不把第一军的四师人散开，反把他们聚拢的那种奇怪的误会，每排二百人，前后连接二十七排，许多那样的队形齐头并进去和开花弹对抗，炮弹对那些密集队伍的骇人的射击，失去连络的先锋队，从侧面进攻的炮队突然受到拦腰的袭击，布尔热瓦、东泽洛和迪吕特被围困，吉奥被击退，来自综合工科学校的大力士维安中尉，冒着英军防守热纳普到布鲁塞尔那条路转角处的炮火，在抡起板斧去砍圣拉埃大门时受了伤，马科涅师被困在步兵和骑兵的夹击中，在麦田里受到了贝司特和派克的劈面射击和庞森比的砍斫，他炮队的七尊炮的火眼全被钉塞，戴尔隆伯爵夺不下萨克森－魏玛亲王防守的弗里谢蒙和斯莫安，第一○五联队的军旗被夺，第四十五联队的军旗被夺，那个普鲁士黑轻骑军士被三百名在瓦弗和普朗尚努瓦一带策应的狙击队所获，那俘虏所说的种种悚听的危言，格鲁希的迟迟不来，一下便倒在圣拉埃周围的那一千八百人，比在乌古蒙果园中不到一个钟头便被杀尽的那一千五百人死得更快，凡此种种迅雷疾风似的意外，有如阵阵战云，在拿破仑的眼前掠过，几乎不曾扰乱他的视线，他那副极度自信的龙颜，绝不因这些变幻而稍露忧色。

根据实验研究结果，再结合上述的病机假说，我们认为本实验证明了少、弱精性不育患者精浆中出现了"精瘀"的中医微观证，"精瘀"为其主要的病理变化；在病机演化中，肾虚是不育疾病之本，血瘀是肾虚的继发病理产物，血瘀日久会导致肾虚；并对肾虚-血瘀-不育三者关系作了理论探讨，对聚精汤的(来源：A5a2a2aBC论文网www.abclunwen.com)组成药物进行了本草析微、方义剖析，得出补肾活血法治疗此疾病不但有理论基础，也有实验依据，补肾活血法是治疗这类疾病的有效法则；还提出可以把uPA看作"精瘀"的实验指标，这对男性不育的病因分析、疗效观察、预后判断有一定的来源：A7676BC论文网www.abclunwen.com

The geology research of carbonate reservoirs in Ordovician of Tahe oilfield showed that many large dissolved vugs and fractures were developed. The spread of the reservoir take on a very heterogeneous state. And the typical fractured-vuggy reservoirs was formed. According to the combination of the various spaces, the formation was divided into vuggy formation, fractured-vuggy formation and fractured formation. The research showed that development of the vug is relevant to the its position on the structure, the fractures, the water surface and the weathering surface. Multi-phase charge and recharge of the oil in the reservoirs resulted in the complexity of the fluid distribution. So the"Bottle Model"was brought forward to explain the movement of the water-oil contact. The special storage space and the complex fluid distribution lead to the unstability of the production and the complexity of the water cut. In order to explain the characteristic of the fracture-vug unit was brought forward and the basic principle and method of the partition of the fracture-vug unit was formed. The classification and evaluation of the units were performed according the reserve and energy. Based on the research of geology characteristic and the fluid flow in the reservoir the comprehensive numerical simulation plan of the fractured-vuggy reservoirs were established. Through the selection of the simulation unit, fluid flow type and parameter equivalent the triple media reservoir simulation model was established. Considering the practical application the model was resolved by the DKR decomposition conjugate grads method. Based on the fine reservoir description of Dsitrict IV of the Tahe oilfield the various space type were classified and combined together. The geology model of Unit S48 was constructed. Two typical single well model was established according to the geology and the dynamic phenomena. Finally the single well model and the Unit S48 were simulated by the triple media reservoir simulator. Via the local grid refinement and coarsening in the simulation good matchs were gained. Based on the results of the simulation the reserve distribution, percent of reserve produced in various space and the natural energy were analyzed. The fluid was storaged in the fractures and vugs mostly and more than 90% the produced oil came from the systems. The energy belonged to the active one. The results of simulation accorded with the fact and showed the validity and practicability the research and the simulator.

Cameras and road sensors aim to give drivers advance warning of problems, but many roads are not covered and the information can be unreliable. Many digital maps use only signposted speeds to calculate journey times and take little account of the way traffic flows change during the week and at different times of the day.

摄像头和交通传感器就是为了给司机一个预警信号，但是很多路面并没有被覆盖，有的信息也不可靠，很多电子地图只是用路牌商标的速度值来计算行程时间，很少描述一周内，或者每天中不同时间段路上的交通流量变化翻译：sensor 传感器 unreliable，不可靠的，不可信的 signpost，路标 calculate计算

In songs like "Shine,""Take Me to Your Leader,""Spirit Thing," and "Step Up to the Microphone," the Newsboys magically melded a modern pop beat with a strong, spirit-filled message.

不过从2000年起，它们有一些不一样的动作发生——团员纷纷单飞出专辑，许多的乐队成员变化了。

If we want to get the effective mass by the method of computing the meson self-energy , we need to consider the change of the effective mass of the nucleon along with the increasing density of the nuclear matter,namely considering the fluctuation of the vaccum.

很多研究[3，4，5，6，11，12]表明了上式描述的规律是正确的，如果用计算介子自能的方法来得到介子的有效质量，需要考虑核子的有效质量的随核物质的密度的变化，即需要考虑核子的真空涨落，当不考虑核子有效质量随核物质密度变化的时候，ρ介子、ω介子的有效质量一般是上升的。

After all, any reality is just a fact of change – an unconfirmed moment in the slow march of time. The present always surpasses the past, and the future will not care about today.

既确定而又不真实，毕竟任何的现实都是变化中的事实，是漫长的时间中不确定的片刻，现在总是覆盖着过去，未来也不将理会今天。

But many anthropologists and futurologists say the arrival of such unpleasant evolutions could happen much earlier – within 1,000 years.
