例句与用法

1. by using the matlab, we obstain their numerical simulation pictures . then, with the new assumption on the solution, we change the disturbance equation with v " = k ( \-v2 ) and reconstruct the soliton solutions of the reaction and diffusion equations and the nonlinear wave equations . we find that they all have a kind of complex linear soliton solution
   接着，我们调整“扰动”方程的形式为v=k(1-v~2)，利用对解的新假设，重新构造了一类反应扩散方程和一类非线形波动方程的孤立子解，发现它们都有一种复线性孤子解。
2. [objective ] obstain the chitinase producing strains inhibiting pathogen fungi and the a plicaion technology and explore the mechanism of antifungi strain [ content ] obtained one or several chitinase secreting strains capable with inhibiting pa thogen fungi found out the premium conditions and measuring the effect of inhibiting to pathogen fungi . this experiment explore the mechanism of strain's fermented liquids by examinng the effect of rice defensive enzymes activity
   目的获得对病原真菌有较好抑制效果的几丁质酶产生菌及其应用技术，初步探索拮抗菌的作用机理。内容分离纯化对病原真菌有较好抑制作用的几丁质酶产生菌，优化产酶条件，研究拮抗菌株对一些病原真菌的抑菌效果，探讨拮抗菌发酵液对水稻幼苗保护酶活性的影响。
3. we write the program which used for fighting errors in absolute positioning . we also write the program which used for linear combinating in absolute positioning . from analyzing for the measurement of outer, we can conclude that we can use m estimation to estimate parameter in gps absolute positioning . lt has application value . using it, we can obstain the stable positioning result and remove the outer . in this paper, we calculate the data which from the baseline space of the gps calibration space . we also draw some conclusion using broadcast ephemeredes and smoothing pseudoranges . the positionging precision is in 1-2 meter
   编制了gps绝对定位中抗差估计程序和应用线性组合进行单点定位的程序。通过对粗差量级的分析，得出在gps观测量存在粗差时，m估计是有其应用价值的，它使定位结果较为稳定，减弱和剔除了粗差的影响。应用线性组合程序对gps综合检定场数据基线网点进行计算，得出用广播星历和平滑后的伪距可以给出较好的结果，点位精度在1?2米。
