In many practice problems such as to know the resonnance frequency of a structure and to know the critical value for the stability of a dynamical system,often need to compute the eigenvalues of a symmetric matrix. The chief method to compute the eigenvalues of a symmetric matrix is first to transformate the matrix to a symmetric tridiagonal matrix similarly and orthogonally, then to use the QR method with shift to the symmetric tridiagonal matrix.

很多实际问题，如求结构振动的固有频率，动力系统稳定性的临界值等常常归结为计算对称矩阵的特征值，而首选的计算方法是先把该矩阵正交相似变换成一个对称三对角矩阵，再对这个对称三对角矩阵用带位移的QR方法。1968年J.H。

By the changing tendency of N, P, K, we coudle see N, P decreased significantly, especially P, the concentration of which was deficient for Chinese Fir nomal growing, but K nutrients were unnoted. So we suggestted increasing N, P fertilizer for Chinese Fir normal growing and might rise its yield.

由N、P、K的变化趋势可以看出，在杉木生长的整个周期，N、P含量降低明显，特别是P，其含量远低于杉木生长所需要的P含量的临界值，处于严重缺乏状态，K含量变化不明显，因此，建议在生产中增施N、P肥，以保证杉木正常生长，提高产量。

A nonlinear evolution equation for the radiation field in magnetically insulated transmission line oscillator is derived and the threshold conditions of the nonlinear unstable solution are studied.

导出了磁绝缘传输线振荡器中辐射场的非线性演化方程，并讨论了在临界值点附近可能出现非线性不稳定解的条件。

A "what-if" analysis method based on changing all kinds of bounds and parameters is developed to offer more decision information.

通过改变各临界值和求解过程中产生的参数，模型支持各种假设分析。

The limit distributions of the test statistics are the functional of wiener process,so the critical values can only be obtained by simulation.

本文通过对维纳过程的随机积分进行仿真，估计基于PVECM的综列协整检验的临界值。

The results showed that the higher thedischarge voltage or charge capacitor was, the higher the temperature of the plasma was,and the longer plasma discharge time was. There was a late discharge when the inputenergy reached the critical value. The greater the capacitance or voltage was, the earlier thelate discharge of the plasma was. The temperature changes of plasma at the beginning of alate discharge were not significant under different discharge conditions. Each SCB had itstemperature range respectively.

结果表明：放电电压或充电电容越大，等离子体温度越高，等离子体的放电时间也越长；对于不同的SCB，当输入能量超过一定的临界值后，将产生等离子体后期放电；电压或电容越大，后期放电开始的时间越早，而后期放电开始时的等离子体温度，在不同的放电条件下变化并不大，不同的SCB均有其各自的温度变化范围。

Different centile thresholds might be selected to optimize sensitivity versus specificity for DM versus CVD prediction if surrogate IR measures are used for risk prediction

如果IR替代测量用于风险预测，则可选出十分位数临界值上的差异，以优化用于预测DM vs CVD的敏感性vs特异性。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
