In this paper, micro-rock mining in the breakdown of elastic waves generated by the information source, application of rock mass elastic wave and the related breakdown of the theory and technology, to explore unknown goaf water accumulation and nucleation process, found the exact elastic wave velocity than the VP/VS, the amplitude ratio VSH/VPH, spectral, waveform, and frequency of abnormal microseism.
本文以采动岩体微破裂产生的弹性波为信息源，应用弹性波与岩体破裂的相关理论与技术，探索地下采空区不明水体的蓄积和成核过程，发现存在确切的弹性波波速比VP/VS、振幅比VSH/VPH、波谱、波形以及微震频度的异常。
Increased plasma and urine levels of elastin-derived peptides have been reported in COPD patients when compared to those in nonsmokers.31323334 Also, urinary excretion of desmosine, a marker of elastin breakdown, was reported to be higher in subjects with COPD than in nonsmokers.3536 However, the levels of elastin breakdown products also were elevated in smokers without COPD, 3237383940 which suggests that, while active inflammation triggered by chronic cigarette smoke can lead to the destruction of elastic fibers in all smokers, other factors may be at play in those who subsequently develop clinical COPD.
目前已经有COPD患者较不吸烟人群的血浆与尿液中弹力蛋白源性的肽浓度的升高的研究报道。也有关于COPD受试者尿液中的锁链素浓度作为弹力蛋白分解的标记较不吸烟人群增高。但是，弹力蛋白分解产物浓度的升高也出现在吸烟非COPD人群中，这提示了当慢性吸烟触发了活跃性炎症，后者会引起所有吸烟人群的弹力纤维的破坏，而其他因素则有可能在发展为临床COPD的人群中起到作用。
As mentioned earlier, elastinolysiss thought to be an essential component of emphysema.3 This is supported by both pathophysiologic and biochemical investigations, which show reduced lung elastic recoil, disrupted elastic tissue structure, higher circulating levels of elastin peptide breakdown products, and higher levels of desmosine in urine and lung secretions.3 Of the macrophage-derived MMPs identified in emphysematous and COPD tissue, the gelatinases MMP2 and MMP9 are elastinolytic.
正如早些时候提及的，elastinolysiss被认为是肺气肿的主要成份之一。这可以由病理生理研究与生化研究所证实，这两项研究同时提示肺弹性活力的降低，弹性组织结构的断裂，弹力蛋白肽分解产物循环水平的增高，以及尿与肺脏分泌物中锁链素水平的增高。在气肿型或COPD组织中，经确定的巨噬细胞源性的金属蛋白酶中，elastinoly的MMP2与 MMP9是elastinolytic。
For example, Figures (detailed breakdown of the 1.2million number) at this level of specificity are meant to impress, but the emigre approach to numbers is quite elastic.
举例说，如此具体程度的数字(对120万数字的明细分类)，目的就是要打动人心，但流亡人士处理数字的手法却颇弹性。
The program for Non-Newtonian EHL numerical analysis of ball dropping and rebounding is made and Reynolds equations at every moment are solved and modified. The location and relation of the first and second pressure spike are analyzed. The possible time of oil film breakdown, the influence of effective elastic modulus and the drop height on pressure distributions and oil shapes and the damp of lubricant oil on the ball are indicated.

In addition, the breakdown threshold formula was also obtained after considering the energy loss of electron elastic collision and recombination.
考虑电子弹性碰撞损耗、电子复合损耗影响，给出了新的击穿阈值公式。
The piezoelectric structural systems like many other structural systems contain many stochastic factors. For example, the loads which act on the structures, the trim size of the components, the elastic module of the structural material, and their breakdown strength are stochastic;
压电结构系统像其他结构系统一样，有很多随机性的因素，例如结构所承受的荷载、构件的实际尺寸、结构材料的弹性模量、及其破坏强度都是随机的。
The effect of applied stresses on the critical chloride concentrations of prestressing steel wires On the one hand, the presence of sufficient chloride ions in concrete causes breakdown of the passive films on the steel surface and leads to corrosion of the steel, on the other hand, when the applied stress exceeds the elastic limit, the plastic deformation of the prestressing steel wire is produced.
外部施加应力对预应力钢丝临界氯离子浓度的影响一方面当混凝土中的氯离子浓度达到其临界值时，钢筋表面的钝化膜便会破坏，从而导致钢筋发生腐蚀；另一方面当作用于预应力钢丝的外部施加应力超过弹性极限时，预应力钢丝便会发生塑性变形。
For moisture and heat sensitive high polymer materials, when considering the problem of elastic breakdown induced by moisture and heat, the strain energy release rate at the crack tip can be expressed as an integral form.
