The experimental results for the isotones with Z≤14 and 28P can be described well by the modified Glauber theory of the optical limit approach.

对Z≤14同中子异位素和28P的实验数据结果可以用改进的光学极限近似的Glauber理论很好地描述。28P的反应截面能够用扩大核芯以改进的Glauber理论来解释。

And it was found that: certain good effects could be obtained in wood color improving treatment by single bleaching; the effects were not obvious using the prescriptions of sulfides; but the effects were obvious using the prescriptions of hydrogen peroxide or Javel water, and good bleaching effects could be gained.

结果发现：单纯漂白可获得一定的材色改良效果；硫化物类药剂配方，效果不明显；双氧水类、次氯酸钠类药剂配方，效果明显，可得到很好的漂白效果。

The contributions ofΨp from the pion and the kaon meson, the contribution ofΨB from B meson are not very small, and can not be safely neglected for giving more resonable results of form factors.The B meson wavefunction is a major source of uncertainty in the study of B meson decays. The B→πand B→K transition form factors provide a good platform to determine the possible regions for the two typical phenomenological parametersΛandδ.

但π、K介子波函数中的Ψp和B介子波函数中的ΨB对形状因子的贡献比较大，为了获得更加合理的形状因子的结果，一般不能忽略π、K介子波函数中的Ψp和B介子波函数中的ΨB项的贡献。B介子波函数是B介子衰变中不确定性的一个主要的来源。B→π和B→K跃迁形状因子为确定两个典型的唯象参数Λ和δ提供了一个很好的平台。

As a result silver chai n forest land has a better capacity in soil and water conservation than naked l and. It can reduce surface runoff than naked land when rainfall changes around 3 0mm. In 2000, 179.42 g/m~2 soil were lossed in silver chain forest land, 980.1 g/m~2 in naked land on the contrary.

结果表明，与裸地相比刺槐林有很好的水土保持作用，能明显地减少地表径流和泥沙侵蚀。3 0 mm左右降雨量，有林地减少地表径流的能力是无林地的 3倍以上。2 0 0 0年径流观测场有林地土壤流失量为 179.4 2 g/ m2 ，无林地土壤流失量为

The results show that present model can effectively describe the scale-dependent long-tailed phenomena of experimental results and be used as general filtration model.

研究结果表明该模型能很好地刻画实验曲线中出现的与介质尺度相关的拖尾现象，可作为更一般的过滤模型。

The X-ray analysis of the chiral macrocycle Ⅲb shows that the chiral ligand with acavity is rather rigid and strained. The unsymmetrical spatial structure of Ⅲb wellexplains the different recognition to chiral small molecules.

结果表明大环Ⅲb是具有一定大小空腔的扭曲型刚性分子，这种环系的不对称空间结构能够很好地解释它对手性小分子的不同识别作用。

The base of this anode is titanium plate, the mesosphere is composed with SnO2-Sb2O3, and plating SnO2-Sb2O3-IrO2 as the surface layer.

各项测试结果显示，该电极是以SnO2为基础的纳米级固熔体氧化物电极，具有很好的稳定性。

Good chromosome preparation methods are necessary to get good spreading of chromosomes within metaphases for karyotype analysis.

染色体标本的制备是核型分析最基础的工作，要制作高质量的染色体标本，获得可靠的镜检结果，必须要有很好的制片方法。

Good chromosome preparation methods are necessary to get good spreading of chromosomes within metaphases for karyotype analysis.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
