求船舶空间浮态就是计算船舶在某种给定载况下的三个浮态参数，它归结为求解一个隐式非线性方程组。
The ship's floating condition calculation aims at obtaining three floating condition parameters. It can be attributed to solving an implicit nonlinear equation group.
以加速寿命方程作为应力模型，解决利用不同环境应力下可靠性增长试验数据，求试验结束时设备可靠度的置信下限问题。
In this paper, we analyze reliability growth data from different stress environments. We adopt the accelerated life equations as the stress model and obtain the confidence of the reliability.
可惜的是，当采用一个十分庞大的附加参数组时，在某些几何条件下将导致很坏的法方程系状态，从而使测求的平差结果很差。
Unfortunately, introducing a comprehensive set of additional parameters can produce a bad condition for normal equations under certain geometry, so that the adjusted results are poorly determined.
