After lighting the firearms set off,the solid nitrogen grain is quick to gasify,the nitrogen of large quantity nitrogen spirit blows to rise the air sac immediately,and in the mighty impact dint under,the air sac hurtles to open the cover on the steer device but the safety launche.

在正驾驶位的气囊装在方向盘的中间位置，副驾驶位的安全气囊安装在正前方的平台内部，在意外发生的瞬间可以有效的保护驾驶员和副驾驶位乘员的头部和胸部，因为正面发生的猛烈碰撞会导致车辆前方大幅度的变形，而车内乘员会随着这股猛烈的惯性向前俯冲，造成跟车内构件的相互撞击，另外车内正驾驶位置的安全气囊可以有效的防止在发生碰撞时方向盘顶到驾驶者的胸部，避免致命的伤害。

The country now has 300 to 400 people receiving ARV who are actively sharing their experiences in the community. In 2003, of the 100,000 people who required treatment, about 12,000 are now receiving ARV, with about 95% adherence.

这个国家现在有300到400位积极地在社会上分享他们的经历的人正接收ARV治疗，2003年，于100，000位需要治疗的人们当中，有12，000位目前正接收ARV，其中有95%比率的人持续著。

Since an elementary reflection in the form of a Householder matrix can reduce any orthogonal matrix to this constrained form, a series of such reflections can bring any orthogonal matrix to the identity; thus an orthogonal group is a

objective: to evaluate the clinical application of helical ct for the location or treatment of maxilla embedded tooth in the dental orthopaedics.method: 18 cases with embedded tooth of maxilla were made with clinical examination, dentomaxillary pantomography, submaxilla lateral projection and helical ct.the operation be done for supernumerary tooth,distorted teeth,inverted tooth.three embedded tooth of non-inverted tooth were done by orthopaedics.result: among the 18 embedded tooth ,there were 11 palatally and 6 labially presented teeth,1 the 18 patients is mediately with completely inverted supernumerary tooth.all preoperative assessment are one and all in operative or orthopaedics and primary wound healing.

四川大学华西口腔医学院正畸科，四川成都 610041摘要：目的：正畸治疗中对上颌埋伏牙如何定性，定位，并要对此是采取手术拔除［1］或者是正畸治疗进行探讨。方法：对18例（其中1例为2颗多生牙，1颗多生牙已长出，另一颗为完全倒置的多生牙），上颌前部埋伏牙采用临床检查以及拍摄全景片、头侧位片螺旋ct轴位和表面成像等检查［2～4］对埋伏的多生牙、畸形牙和倒置牙共15例采用了相应的手术进路拔除，对形态正常且不倒置的3颗埋伏牙采用了正畸治疗。

The Trojans led by him and by Iamenus, Orestes, Adamas the son of Asius, Thoon and Oenomaus, raised a loud cry of battle and made straight for the wall, holding their shields of dry ox-hide above their heads; for a while the two defenders remained inside and cheered the Achaeans on to stand firm in the defence of their ships; when, however, they saw that the Trojans were attacking the wall, while the Danaans were crying out for help and being routed, they rushed outside and fought in front of the gates like two wild boars upon the mountains that abide the attack of men and dogs, and charging on either side break down the wood all round them tearing it up by the roots, and one can hear the clattering of their tusks, till some one hits them and makes an end of them- even so did the gleaming bronze rattle about their breasts, as the weapons fell upon them; for they fought with great fury, trusting to their own prowess and to those who were on the wall above them.

就像这样，二位凭待自己的勇力和强健的臂膀，站候着高大的、正向他们迎面扑来的阿西俄斯，毫不退让。特洛伊人直冲而上，对着修筑坚固的护墙，高举着生牛皮做就的战盾，裂开嗓门呼喊，围拥在首领阿西俄斯身边，围拥在亚墨诺斯、俄瑞斯忒斯和阿西俄斯之子阿达马斯，以及俄伊诺毛斯和索昂的身旁。其时，墙内的拉丕赛人正极力催促胫甲坚固的阿开亚人保卫海船，但是，当他们看到特洛伊人正冲向护墙，而达奈人则惊叫着溃跑时，二位冲将出去，拼杀在门前，像两头野猪，在山上站等一群步步进逼的对手，骚嚷的狗和猎人，横冲直撞，连根掀倒一棵棵大树，撕甩出一块块碎片，使劲磨咬着牙齿，发出吱吱嘎嘎的声响，直到被人投枪击中，夺走它们的生命――就像这样，挡护他们胸肩的捏亮的铜甲承受着枪械的重击，发出铿锵的震响。

The cause of hard agglomerate formation and its effect on sinterability were investigated. The water-washed ZrO〓-Y〓O〓 powders were found to be greatly made up of hard agglomerates. The ethanolwashed powders also contained a few of hard agglomerates because of uneffective dehydration. Beside, ethanol volatilizes in advance of water during drying because ethanol has a lower boiling point than water, so steric effects of ethanol won't act. However, nearly no hard agglomerate formed in the azeotropic distilled powders, because of effective dehydration and higher boiling point for n-butanol.

研究指出，水洗工艺所得ZrO〓-Y〓O〓粉末几乎完全由硬团聚组成；乙醇洗涤工艺的脱水效果不是很好，并且由于乙醇的沸点比水低，以致在干燥过程中残留乙醇比水先挥发，乙醇的空间位阻效应不能有效地发挥作用，因此，仍然可以导致产生一定量的硬团聚；而共沸蒸馏工艺的脱水效果最佳，且正丁醇的沸点比水高，干燥时残留正丁醇比水后挥发，从而正丁醇的空间位阻效应可有效地发挥作用，因此避免了在煅烧过程中形成Zr-O-Zr键，即共沸蒸馏粉末中不含硬团聚。

At driving bit mounted on the steering wheel airbag middle position, co-pilot-bit airbag installed in front of the platform itself, the accident happened at the moment can effectively protect the driver and co-occupant spaces of the head and chest, because facing fierce collision will happen cause the vehicle in front of large deformation, and the vehicle occupant as the inertia of this heavy dive forward, causing the car with each other percussive elements, while driving the location of the car airbag can effectively to prevent the steering wheel when the collision happened at the top of the chest to the motorists to avoid the fatal injuries.

The physiology characters of the leaf of ear in different periods have been studied It is showed that the water content and protein content,leaf_area and protein weight per square of leaf of ear from silking to 42d after silking all reduce gradually , but dry-weight and leaf -area did not do The correlate analysis showed that the protein content of leaf of ear in different periods and protein- weight per square did not correlate significantly with protein content of seed Dry weight of leaf of ear was ...

研究不同时期穗位叶的部分生理性状表明：从吐丝期至其后 4 2d ，穗位叶的含水量、单位叶面积、蛋白质含量和单位叶面积蛋白质重量均呈现一个逐渐下降的趋势；穗位叶叶片干重和叶面积基本保持不变。相关分析表明，不同时期穗位叶的蛋白质含量、单位叶面积蛋白质重量与子粒蛋白质含量无关，而吐丝期穗位叶干重和子粒蛋白质含量呈显著正相关
