2. But pile jacking took place in semi-infinite space, the difference of stresses in boundary between semi-infinite space and infinite space should be analyzed. 实际上，压桩问题属于半无限问题，必须考虑从无限问题转化到半无限问题后地面边界处应力的差异。
3. The MRTD source with target and plane blackbody is imaged at infinite place to simulate the infinite target by using infrared optic system, so as to be received by thermal imaging system. 靶标和面源黑体组成的温差源通过红外光学系统成像到无限远，模拟无限远目标，供给热成像装置接收。
4. Infinite/at which gravitational forces cause matter to have infinite density and infinitesimal volume, and space and time to become infinitely distorted. 时空中的一点，在该点重力使物质的密度无穷大、体积无穷小，空间和时间被极度的扭曲。
5. The inverses of infinite matrix on a division ring are discussed. The decomposition theorem of infinite matrix on a division ring is proved. 对除环上无限方阵的逆方阵作了简单讨论，证明了除环上无限方阵的分解定理。
