| 4. | Fortunately for tennis players , the serosa from a cow ' s intestine fits the bill nicely
对于球员所幸运的是，牛的肠子的绒毛膜足以应付比赛。 |
| 5. | The collagen found in serosa has a molecular make - up that is designed to withstand the stretching and contraction of the intestine
绒毛膜上的胶原是以分子形式聚合，从而承受住肠子的拉伸和收缩。 |
| 6. | Once the serosa ribbons have been washed , and any impurities removed , they are subjected to another round of quality control

| 7. | However , the serosa is only a small part of the intestine and it takes about three cows to produce one set of tennis string
然而，绒毛膜只是肠子的一小部分，所以3头牛的绒毛膜才能制造出一根网球线。 |
| 8. | Some manufacturers believe so , and buy their serosa from specific sources in an attempt to maintain a consistent quality
一些制造商对此深信不疑，于是买这些地方的牛的绒毛膜去制造肠线，以获得持久的高质量。 |
