| 1. | For each double cone, the opposite pulls from two parts of the sphere exactly cancel .
就每一双锥面来说，球壳的两个部分所产生的相反引力正好对消。 |
| 2. | A particle inside the shell is drawn equally in all directions and experiences no force at all。
在球壳内部的质点，因被对等地吸引向各个方向，所以完全没有感受到力。 |
| 3. | The integration corresponds to adding successive shells to the core until the core has radius r .
这个积分相当于把一系列球壳加到球核上，直到球核的半径等于R时为止。 |
| 4. | The compatible boundary conditions are evidently uniform tractions applied on the inner and outer surfaces of the shell .
可相容的边值条件显然是作用在球壳的内表面和外表面上的均匀曳力。 |
| 5. | The motion of the shell due to an impulsive pressure may be examined in the same fashion as in the case of the cylinder problem .
由脉冲式的压强引起的球壳的运动，可以按照在圆管问题中所用的同一方式来进行分析。 |
| 6. | Dynamic stress field of spherical anti - penetration plate
球壳形遮弹板动应力场的试验 |
| 7. | Threaded connectors are welded to the bulb
螺纹连接是焊接到球壳上的。 |
| 8. | Cable and bulb built a fixed connection
电缆和球壳有固定连接。 |
| 9. | Counter - ion distribution in a sphere kernel - shell with different couplings
球壳系统的反离子分布 |
| 10. | The thermometers are supplied with flexible sheath or rigid bulb
该温度计有灵活的外壳或坚硬的球壳。 |
