结果：①撞击颏部，其舌侧区，磨牙后区内侧面、髁状突颈外表面以及下颌角外表面具有较高的张应力；②撞击下颌体部，颏部舌侧区，对侧磨牙后区内侧面、对侧下颌角外表面、撞击侧下颌角外侧面、撞击侧体部内侧面具有较高的张应力；③撞击下颌角，其内侧面、撞击侧髁状突颈内侧面、颏部舌侧面、对侧髁状突颈外表面以及撞击侧磨牙后区内侧面具有较高的张应力。

The zirconium film withoul zirconia wasprePared and the removing technology of the zirconia on the zirconium suthees wasNned.The method of high temPeratUr vacuum hydrOgenization Which was firstlystudied was used tO remove the okide film of zirconium on the sdses.

本文针对这种情况，首次进行了以下几方面的研究：首次采用电化学法研究了锆膜基材表面氧化层的去除技术，制得去除了表面氧化膜的锆基材膜，获得了锆膜基材表面氧化层的去除工艺。

Under the influence of the sunlight and with the help of its strong oxidization capacity, the photo-catalyst can oxidize nearly all the organic matters on the surface into H 2 O and the corresponding nontoxic inorganic materials. At the same time, under the combined actions of the characteristic nanometer structure of its surface, the hydroscopic properties of the complex additives and the light-induced amphiphilic properties (hydrophilicity and lipophilicity) of Ti02 itself the surface of the glass is made superhydrophilic, so that it becomes easily washable, anti-fog and not vulnerable to recontamination to keep the glass clean and transparent. And it also has such functions as sanitization, sterilization, foreign odor elimination and air refreshing.

在阳光的作用下，光催化剂以其特有的强氧化能力，可将其表面的几乎所有有机物完全氧化为H 20及相应的无害无机物，同时在其表面特有的纳米结构、复合添加剂的吸水性和Ti02本身的光致两亲性的共同作用下使玻璃表面具有超亲水性，变得易清洗、防雾和不易被再污染而保持洁净透明，同时具有消毒、杀菌、消除异味、清新空气等功能。

Results show that the alumina formed on the corroded NiCoCrAlY coating is roughness, cracked and incontinuous and many pits was formed on the surface of the coating after the salt-spray test.

试验结果表明：经过盐雾腐蚀的涂层表面的均匀性和完整性均被破坏，涂层表面产生了大量的腐蚀坑；高温循环氧化以后，表面形成的Al2 O3 氧化膜变得粗糙、破碎且不连续，而且氧化膜容易剥落，降低了涂层的高温抗氧化能力，缩短了涂层的使用寿命

Because of the especial requirement of gear form of preshaving hob The design of preshaving hob is more comples than common gear hob.The design method is inefficience,takes much time,and requires highly of designers.

拉刀也是机械加工中常用的一种刀具，拉削可加工内表面（如各种型孔、键槽、花键孔等）和外表面（如平面、半圆弧面和组合表面等）拉削加工效率高，精度高。

The hydrophobic adsorption film gradually grows and passivates on jamesonite from -78 mV to 42 2 mV.The electrode process of jamesonite at 522 mV is quite controlled by the reaction that is depended on ion diffusion.When the electrode potential is over 622 mV,the hydrophilicity on jamesonite becomes strong due to covering an amount of PbSO4 from the electrochemical reactions.

当电极电位为-78 mV～422 mV，矿物表面疏水性膜逐渐增长并产生钝化作用；当电极电位为522 mV时，电极过程完全由离子扩散决定的电化学反应所控制；当电位大于622 mV后，电极反应产生大量的PbSO4沉淀，并覆盖在电极表面，矿物表面的亲水性强。

After HRP application, HRP labelled cells were distributed in the nucleus of trapezoid body , lateroventral periolivary nucleus , retrotrapezoid nucleus , lateral paragigantocellular nucleus and lateral reticular nucleus . The findings demonstrated the existence of neural structural relations between the chemosensitve areas and the Tz, LVPO, NRT, LPGi and LRt, and revealed that these nuclei might participate in the mechanism of central chemical regulation on respiration.

观察到用浸有HRP的滤纸局部敷贴于延髓腹外侧表面化学感受区后，在延髓斜方体核、外周橄榄腹外侧核、斜方体后核、巨细胞旁外侧核和外侧网状核等核团找到HRP标记的细胞，表明上述延髓内部核团与腹外侧表面化学感受区之间存在神经结构联系，提示延髓腹外侧表面化学感受区对H〓等物质的化学感受机制可能与上述核团神经元伸向该区的突起有关。

The surface chemical properties of the latices and the composition of the surfactants on the particle surface revealed the synergy between C12E6.3 and dodecylbenzene sulfonic acid. They form a mixing interface film.
