查询词典 Cavitated

Stability of solutions of the cavitated bifurcation equation is discussed in each region by using the minimal potential principle, and the catastrophic phenomenon of cavity formation is explained. 2. In Chapter 4, problems of cavitated bifurcation for two spheres, which are composed of two different kinds of imperfect compressible hyper-elastic materials, were examined, respectively. The parametric analytic solutions of the radially deformed function and the parametric cavitated bifurcation solutions are all obtained for the two spheres.

Results By using optical microscope,the neurocytes of hippocampus in experimental group were observed to denaturalize,tumefy,destroy and disappear.And under electron microscope,the karyon was irregular,nucleoles deviated,chondriosome tumefied,crista collapsed,membrane was damaged,substance cavitated.Such changes were more evident with the increased paroxysm of epilepsy,the parameters between control group and operation group had no difference（P＞0.01）.But make a monofactorial variance analysis among cells' number,area,circumference and integral optical density in different groups,it showed that there were significant differences between optional two groups（P.01;at the same time,the more serious injury in hippocampus,the more powerful GFAP immunoreaction was.

气蚀发生的条件与气泡密切相关，气泡在真空时从钻井液中溢出形成气团，并紧靠缸壁；气团在压缩时因承压能力低而产生爆炸，从而引起缸壁产生气蚀作用。

In contrast to the situation for a homogeneous isotropic neo-Hookean sphere, it is shown that not only there exists a secondary turning bifurcation point on the cavitated bifurcation solution which bifurcates locally to the left from trivial solution, and also the critical load is smaller than that for the material with no perturbations, as the parameters belong to some regions.

与均匀各向同性的neo-Hookean球体的情况相比，证明了当摄动参数属于某些区域时，从平凡解局部向左分岔的空穴分岔解上存在一个二次转向分岔点，空穴生成时的临界载荷会比无摄动的材料的临界载荷小。

The optimum process was as follows : solvent is 0.3% ammonia solution , ratio of solvent to solid ratio is 10:1 , vacuum-cavitated time is 15 minutes , GA extraction yeild is 2.0%, the crude extract is 30.3%, and in which the content of GA is 6.6%.

采用负压空化方法对超临界萃取后固形物中甘草酸的提取工艺进行了研究，并研究了甘草酸纯化的工艺，通过影响因素试验和正交试验得出最佳工艺条件为：0.3%的稀氨水为溶剂，液固比为10：1，负压空化提取15min，甘草酸提取率为2.0%，含量6.6%。

The thought process which underpins this new minimal invasive approach can be organized into three main categories:(1) Recognize, which means identify patient caries risk,(2) Remineralize, which means prevent caries and reverse non-cavitated caries, and (3) Repair, which means control caries activity, maximize healing and repair the damage.

微创牙科学的处理方法可概括为3个步骤：(1)判定患者的患龋风险；(2)再矿化，即防止龋损形成并逆转未形成&洞&的浅龋；(3)修复，即控制龋活性，使愈合潜能最大化并修复龋损。
