ArcSin approximation with minimal error must be found.

在近似的 ArcSin 中，在最小误差允许范围内，肯定可以找到这些值。

The parameters A, B, C and D define the shape of the curve for the function and the values for a fit to theArcSin approximation with minimal error must be found.

参数 A， B， C 和 D 决定了函数曲线的形状。在近似的 ArcSin 中，在最小误差允许范围内，肯定存在这些值。

Needless to say, this is always an approximation—many

不用说，这是一个近似的值，因为有很

Due to their modes to adapt to arid condition, ecological and physiological responses and the changes of structure are all different, but their mechanism to adapt to the sandy soil water changing is consistent, consequently they have more chances to exist in the entironment what has biggish annual wave of climate comparing to mostly plants that bourgeon in early spring.

由于对干旱生境的适应方式各不相同，其生理生态反应和结构的变化因种而异，但对沙土水条件的适应机理却是近似的，从而在年际气候波动较大的生境中，这几种植物较早春期萌发的大部分植物幼苗有较多的存在机会。

Though most rocks are elementally similar, they are mineralogically and texturally diverse.

虽然大多数岩石在元素成分方面是近似的，但它们在矿物成分和结构上却是各不相同。

Though mos rocks are elementally similar , they are mineralogically and texturally diverse .

It is proved that the two-dimensional non-hydrostatic Boussinesq equations on the x ? z plane with the kinetic viscous term and the thermal dissipative term are unstable equations in the C 2 function class.2. If we replace the influence of the kinetic viscous term by Rayleigh friction and the thermal dissipative term by Newton cooling, the new generalized equations are stable equations in the C 1 function class. The construction of the solution space and the discriminating method for well-posedness of the problem of determining solution are given.

本文的主要结果如下：1证明了在y方向上均匀的带有运动粘性项以及热耗散项的两维非静力、Boussinesq近似的x-z面上两维旋转流体的控制方程组在C 2函数类中是一个不稳定的方程组。2如果以瑞利摩擦来代替粘性的影响，以牛顿冷却来代替热量的耗散，则所获得的一个新的方程组在C 1函数类中是一个稳定的方程组，给出了其解空间的构造和各种定解问题的适定性的判别方法。
