Property represents the baseline font size as integral values , rounding errors occur that become evident when a form is cycled through multiple resolutions . automatic scaling was implemented in only the 属性将基线字体大小表示为整数值，所以某个窗体在经历多次分辨率更改后，发生的舍入误差会变得很明显。
We also test another method based on dct transform , find its fault and consider how to avoid . at last , a new method based on dct transform is considered , we test it and get a better result than the two methods we have discussed 在对以上算法进行分析的基础上，我们吸收了dct变换类型算法中分块嵌入水印的思想，但是在对dct变换后的系数进行调整时，采用了逐步调整的算法，避免了dct变换类型算法中的整数舍入误差。
The method is initialization independent and can provide a mathematical and computational guarantee that all solutions of an nonlinear equation are enclosed . " if interval newton algorithm can not find any solution , it can be concluded that there is no solution in the given interval vector 由于能自动处理舍入误差，区间牛顿法不仅能够在理论上，而且能够在计算上保证找到非线性方程组的所有解；若使用区间牛顿法不能找到任何实数解，则可断定在给定的区间向量范围内方程组无解。
Specifically , according to the w - w five parameters failure theory , the fracture criterion of crack is established , and the state of crack ( open or close ) is judged by the values of the crack strain . combining the two points , the predict - model about the failure of concrete material is established . this predict - model can predict 16 failure forms , and basing the different failure form predicted after crack , the stress - strain relationship matrix of concrete material is adjusted 具体来讲，根据w - w的五参数混凝土破坏理论，建立混凝土的开裂准则，根据开裂应变值来判断裂缝是张开还是闭合，从而在两者基础上建立了裂缝的开裂预测模式，总共有16种开裂模式；裂后根据具体的开裂模式及残余抗剪能力来调整混凝土的本构关系矩阵，即用等效刚度代替原有刚度，考虑到垂直于裂缝方向的刚度为零，这样会使裂后的总刚出现病态，为此文中通过引用松弛系数来对出现裂缝的单元进行预处理，一方面可解决因过大的舍入误差导致计算结果的不可信问题，另一方面就是可加速收敛。
A combined gauss main - element elimination method with compress - storage technique is proposed , which with the characteristic of less - storage requirement , small rounding off and high stability , and solved the problem of large storage requirements in solving large linear algebraic equations in river networks hydraulics , 3 提出了压缩存贮形式的gauss列主元消去法，该方法具有存贮量小、舍入误差小、数值计算稳定的特点，在一定程度上解决了河网水力计算问题中关于众多线性方程组的存贮及其求解过程中可能面临的困难。
