As 2-d 3-t heat conduct equations are discretized in a fully implicit method, it is very difficult to solve the nonlinear algebraic equations obtained due to strong nonlinearity.
由于二维三温热传导方程具有很强的非线性特性,因此采用全隐格式对该方程离散后,所得非线性代数方程组的求解将变得非常困难。
Temperature and stress distribution of multi-pass welded T-joint was simulated using ABAQUS codes. 3-d solid elements were used to mesh the model.
应用abaqus软件,对多道焊T形接头的温度场和应力场进行了数值模拟。
Martin Banks, a professor of optometry at Berkeley, says 3-D doesn't allow our eyes to follow the rules because we're focusing on things both far and near at the same time.

This is incredibly important because,when you look at this number that we started out with,saying the benchmark was 9.9 but net of fees the managers on average only lost thirty basis points--or .3% -you'd say,well that's a game I don't mind playing.
这极其重要,因为当你看这些数字时,刚才说过基准收益是9.9%,但是主动管理型基金经理人的平均净利润,只落后了30个基点或者说0.3%,你可能会说这个游戏,我不介意玩一玩
You need to know how to think about them in the same way we think about s and p orbitals, but for example, you don't yet need to know what all of the names are except for this 3 d z squared here.
你们只要知道,如何像考虑s和p轨道一样,来考虑它们,但你们不需要,知道它们的名字,除了这个3dz2轨道外。
