But this was love--this fever, this longing, this restless, uncertain, miserable hesitation; these cruel fears that his age was an insurmountable barrier to his happiness; this sick hatred of his white beard; this frenzied wish to be young again, with glistening raven hair, and a slim waist, such as he had had twenty years before; these wakeful nights and melancholy days, so gloriously brightened if he chanced to catch a glimpse of her sweet face behind the window curtains as he drove past the surgeon's house; all these signs gave token of the truth; and told only too plainly that, at the sober age of fifty-five, Sir Michael Audley had fallen ill of the terrible fever called love.

LaNi〓 can be easily activated at room temperature and activated LaNi〓 possesses catalysing effect for the dissociation of H〓, which greatly reduces the energy barrier for dissociation of H〓. Hydrogen passed through LaNi〓 particles, then diffused into the crystal lattices of V、Nb and TiFe alloy and formed hydrogenate.

LaNi〓粒子在室温下很容易活化，活化后的LaNi〓具有了氢分子分解为氢原子的催化作用，降低了氢分子分解为氢原子所必须克服的势垒，氢通过LaNi〓粒子而进入V、Nb、TiFe合金晶格中，形成金属氢化物。

温度漂移对水听器系统输出的影响是其实用化进程中的关键技术障碍。

Blood barrier, blood loss, the HA does not flow "of blood stasis is" thrombosis modern medicine for its mechanism of hemodynamic changes, abnormal blood stasis, platelet hyperfunction, lower fibrinolytic activity.

血脉不通，血行失度，血凝不流"，所至的血瘀证即为"血栓现代医学认为其机理为血流动力学改变，血瘀异常，血小板功能亢进，纤溶活性降低有关。

Found that the constitution of the absorbent could affect the debinding efficiency greatly; for the liquid phase debinding temperature extent, the mechanism of the absorbent is capillary action, 100~200 screen mesh alumina powder had the best debinding efficiency at 130℃; for the gas phase debinding temperature extent, adding some active carbon to the absorbent could control the formation of the hyperoxide barrier lay, accelerate the mass transfer rate, also enhance the debinding efficiency; studied the relationship between the debinding efficiency and the shape of the green part and the solid load; furthermore, did trial study on the solvent debinding.
