而桑迪亚的电池则只需移动零点几毫米就能有效地跟踪太阳，且其重量微乎其微。

Sandia's cells, on the other hand, would only need to be moved a fraction of a millimeter to track the sun efficiently while weighing next to nothing.

摘要本文利用次线性项在零点附近的凹性和可积性，用移动平面法给出了一类次线性椭圆方程正解的对称性。

With the concavity and integrability of sublinear terms near zero, the symmetry results for a class of sublinear elliptic equations are given by making use of the moving-plane method.
