疏松的

It is the basic reason of increase oxidation that the appetency of Sn-0.7Cu with oxygen is larger than Sn-37Pb and the surface film is loose.

指出Sn-0.7Cu合金与氧的亲和力大于Sn-37Pb，且表面氧化膜疏松，是造成氧化速度快的根本原因；提高表面膜的致密度，是降低氧化反应的根本措施。

Objectives: To investigate the effects of estriol and/or levonorqestrel on the proliferation and differentation in vitro.

目的：国产长效雌激素尼尔雌醇治疗绝经后骨质疏松已取得良好效果，而与左炔诺孕酮联合应用有很大的潜力，所以我们观察尼尔雌醇在体内的代谢产物之一的雌三醇与左炔诺孕酮对OB的体外作用。

For some reasons,people have different opinions of the effects of exercise on preventing osteoporosis.In the article,the effects of exercise on bone mass and bone metabolism in postmenopausal women are discuss...

但关于运动在防治骨质疏松中的作用的文献报道差异性很大，为此本文从运动对绝经后妇女骨量和骨代谢的影响两方面归纳总结运动疗法的作用机制和效果。

As shown in the cycle-stiffness curve, the stiffness was significantly higher for Krag and caudad method than for Magerl method (P.01). Conclusion In osteoporotic lumbar vertebrae, the placement of pedicle screws should not paralled superior endplate and polyaxial pedicle screws should be chosen.

对于骨质疏松患者的腰椎后路椎弓根螺钉内固定手术，常用的螺钉平行上终板的技术不能提供最好的生物力学稳定性。

In accordance with the mean bone mineral density lower than 25% of the standard model group has two parts to achieve an average bone mineral density in osteoporosis standards,show that the model is successful.

按照骨密度均数低于假手术组25%的标准，则模型组两个部位的平均骨密度已达到骨质疏松症的标准，表明造模是成功的。

The manifestation is virtually identical to that of rickets in children, and that of osteomalacia or osteoporosis in adults.

这与儿童的佝偻病或成人的骨软化或骨质疏松在本质上是一样的。suki最喜欢的一个地方是后门处，在那她可以看着叶子被吹得飘落，也可以在阳光里尽情休息。

The current density peak of brass welded line appeared at -0.012 V, and a porous corrosion film was formed. The electrode was passivated subsequently. The passivation film was made up of Cu2O, CuCl and ZnO. The passivation film dissolved with electrode potential, and displacement deposition took place between Cu and Zn. The copper redeposition on the electrode surface induced the increase of electrode activity and corrosion rate.

黄铜焊缝在电位-0.012V时出现电流峰，腐蚀产物膜多孔、疏松，随后电极进入钝化区，钝化膜由Cu2O、CuCl和ZnO组成；随电位升高，钝化膜溶解，发生铜锌置换反应，沉积的Cu导致活性电对的形成，增加了合金的腐蚀速度；当电位为+0.87V时，电极表面富集了针状锡和锡的氧化物。

During osteoporotic fracture healing process ,the abnormal change of the organic constitution, microstructure, bone mineral metabolism and bone mass of callus could result in decrease of mechanical strength or quality of fracture healing which might be the main cause of refracture.

在骨质疏松性骨折修复过程中，骨痂组织的有机成份组成、显微结构、骨矿代谢与骨量的异常改变导致了其力学强度乃至骨折愈合质量的降低，是再次骨折发生的主要原因。

Su steel smelting has two advantages:(1) During the pouring process there is strong oxidation which results in separation of slag and iron the wrought iron being soft in structure and containing large amounts of oxide impurities and also silicon manganese and carbon.

苏钢冶炼高明的地方主要有二点：一是料铁组织疏松，含有大量的氧化夹杂，硅、锰、碳含量也比较高，炼的时候氧化剧烈，造成一定的渣、铁分离。

Due to interference of the geometric size of bone, BMC is not a suitable parameter for clinical diagnosis of osteoporosis.

根据BMC来分析判断，出现峰值的年龄组，男女差别，以及骨质疏松诊断率等都表明受骨骼几何尺寸的影响较大，不适于做为临床诊断的主要指标。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
