null point

The boundary of the single-null diverted plasma in the HL-2A tokamak is simply a circular one plus a local triangular deformation near the X-point.

HL2A的单零偏滤器位形基本上是圆截面加上在X点附近的局部形变。

The null must intersect the emitter at the point where you want to emit particles.

这个空物体必须和发射器有交叉的点以便于从这些部位发射粒子.

Based on the basis of null space and M-P inverse theorem, a unified incremental solution formulae, expressed as the null space basis of the augmented matrix, were firstly formulated herein for the incremental equilibrium equation at the limit point and non-critical points.

根据零空间基和M-P广义逆理论，推导了结构非线性增量平衡方程极值点与非临界点解的统一形式，并直接表示为增广矩阵零空间基的形式。

The device provides extreme sensitivity through a small range around the null point.

此装置在零点附近很小一段范围内具有极高的灵敏度.

There are other places the planet that are difficult to live and that's the null point.

有其他地方的这个星球是很难活,那 就是 在空点.
