In the first 2-3 hours there is always a strengthening of contraction, while after 5-10 hours, when the heart gives much feebler contraction due to exhaustion, this beneficial effect of phosphatide tends to disappear.

二葡萄糖在灌流液中的作用视室温与离体时间而定。在较高室温长期灌流而衰竭的心脏，葡萄糖是必要的，它可以维持心肌收缩并被心肌所消耗。如心脏离体时间较短，室温较低，则葡萄糖并非必需。

The view that phosphocreatine was the direct source of energy for muscular contraction lasted only a few years.

认为磷酸肌酸作为肌肉收缩直接能源的观点，流行了不过数年。

Creatine is a colorless, crystalline substance used in muscle tissue for the production of phosphocreatine, an important factor in the formation of adenosine triphosphate, the source of energy for muscle contraction and many other functions in the body.

肌酸，是一种无色，无结晶物质用于肌肉组织用于生产磷酸，一个重要的因素形成的三磷酸腺苷能源肌肉收缩和许多其他功能的机构。

In order to overcome the shortcomings of acellular dermal matrix used as tissue engineering scaffold material, such as bad permeability, low degradation speed, and strong immunogenicity, a new type of collagen scaffold was prepared by applying various chemical, biological and physical comprehensive methods to deal with pigskin. The microstructure of the scaffold was observed under photomicroscope and scanning electron microscopy, and the in vitro degradation time, permeability, tensile-strength, porosity, shrinkage temperature were tested.

为了克服猪脱细胞真皮基质作为组织工程支架材料渗透性差、降解速度过慢、免疫原性较强等缺点，采用多种化学、生物与物理综合方法处理猪皮制备了一种新型天然胶原支架材料，通过光学显微镜、扫描电镜观察以及体外降解时间、透水汽性、拉伸强度、孔隙率、收缩温度等的测定，对其性能进行了研究。

The microstructure of the scaffold was observed under photomicroscope and scanning electron microscopy,and the in vitro degradation time,permeability,tensile-strength,porosity,shrinka...

实验结果显示：支架中的成纤维细胞、脂肪细胞及组织纤维间质完全去除，胶原纤维得到了松散，并维持其原有的天然三维网络多孔结构；该材料透水汽性处于3000g.m-2.d-1左右，适合创面恢复；体外降解时间处于25～50h之间，并可根据需要调整工艺条件控制降解时间；拉伸强度介于10.20～11.50MPa之间，具有良好的拉伸强度；收缩温度介于70～85℃之间。上述结果表明该材料已解决了猪脱细胞真皮基质渗透性差、降解速度过慢的缺点，并且其透气性和拉伸强度高、降解性优良且可控，符合组织工程支架材料的要求。

The problem of volume shrinkage would happen during the photopolymerization process that turned the liquid into solid instantly.

但是光聚合反应过程是由液态瞬间转变为固态，因此会产生体积收缩的问题。

Thomas Brown[14], poet, philosopher and physiologist in Edinburgh in the first years of the last century.

这种理论只不过是这样的：一个人的行为仅仅[MS13] 是一种肌肉收缩。

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。

Uncovering their weak spots, so I can defeat them.

揭露出他们的弱点，这样我就可以打败他们了。
