The very low N—Cl bond energy in the parent ion of nitrosyl chloride is a clear reason for the absence of ClNO+ and ClN+ ion peaks from the femtosecond laser mass spectrum.
结果表明,ClNO母体离子中键能很弱的N-Cl键是造成飞秒质谱中母体离子ClNO+和碎片ClN+缺失的主要因素。

As far as the quality of the population is concerned, they normally take the mean of population only.
不过有关母体优劣的界定,仍多著重於以母体平均数作为考量的标的。
-
Analytic methods based on elementary parametric and non-parametric models for one sample; two sample, stratified sample, and simple
主要目标是由已知的样本资料经由正确有效的分析来推测母体所具有的特性;另外则是适当地设计样本取得的程序及取样的范围,以便使所观察样本显现的特性能真实反映母体的现象,进而能以简洁的分析,作有效的推论。

The dissertation established the method and VE-AMSAA model of integrated evaluation of reliability based on varied population-environment data by using of reliability growth AMSAA model as foundation. By conversing time of test in AMASSA model, the difficulty in subinterval estimation of this integrated evaluation of reliability was solved and determination of environment conversion factors based on AMASSA model was also presented, including optimizing principle and method.
建立了基于可靠性增长AMSAA模型的变母体变环境数据可靠性综合评估方法和模型VE-AMSAA模型,通过对AMSAA模型中的试验时间进行折合,解决了变母体变环境数据可靠性综合评估的区间估计问题,并给出了基于AMSAA模型的环境折合系数的确定方法,包括优化准则、寻优方法。

Assuming all samples coming from populations with the same standard deviation σ, the accuracy of estimating σ from observations of different parts influences control limits of target control chart. The dissertation points out shortcoming of traditional standard deviation estimates and proposes a unbiased estimate of σ which results in that the variation of the estimate is minimums and the control limits is set more reliably.
假设不同工件的样本标准方差均来自于同一分布,则以不同工件的样本标准方差对母体标准方差的估计的精确性直接影响了目标控制图控制界限计算的可靠性,本文分析了目标控制图传统的两种母体方差估计方法的合理性或稳健性较差的特点,给出了一种对σ无偏估计的优良方法,从而使这一方差估计量〓的散差最小,则依此最小方差的无偏估计量所得到的控制界限更为精确,更为可靠。

The present study indicates that pregnancy cocaine exposure can lead to maternal undernutrition and developmental abnormality of the fetal brain, liver and placenta.
本研究表明,妊娠期给予可卡因能引起妊娠母体营养不良,子代脑、肝脏和胎盘发育异常;可卡因引起的胎儿发育异常是由可卡因的毒性作用而不是母体营养不良产生的。
-
The present study suggested that high levels of plasma IGF-1 of perinatal ewes may related to the growth and development of fetal sheep; cholic acid load may affect IGF-1 production in liver and/or the regulatory function of placenta.
本研究提示妊娠后期绵羊母体血浆高水平的IGF-1可能与胎儿生长发育有关;胆酸负荷可能影响了妊娠母体的肝功能或胎盘的调节作用。

The features of AAA adsorbed on the ethylatedβ-CD polymer were similar with those of the parentalβ-CD polymer, but theadsorption ratios of AAA on the ethylatedβ-CD polymer were higher than those of the parentalβ-CD polymer. It may be due to the strengthened hydrophobic interactions between AAA and the ethylatedβ-CD polymer, which was caused by the ethylation of the parentalβ-CD polymer.
研究表明其对芳香氨基酸的吸附规律与母体β-环糊精聚合物类似;与母体β-环糊精聚合物相比,芳香氨基酸在该聚合物上的吸附率有所增加,这可能是因为乙基化增强了β-环糊精空腔外沿的疏水性,从而增强了乙基化β-环糊精聚合物与芳香氨基酸之间的疏水相互作用。
-
Dates of medusae release of the three growth forms of Millepora at the same site seldom overlaps.
火珊瑚在黄昏开始释放水母体,在日落后会有更多水母体释出。
-
The probability of finding synchronously releasing colonies is much lower between species than within species. And in branch form Millepora, the probabiliy of finding synchronously releasing colonies is much lower between area than within area.
另外在同一地点的三种火珊瑚释出水母体的日期甚少相同,而且种间群体同步释放水母体的机率比种内低;在地点比较上,枝状火珊瑚在同一地点内的同步释放机率比在地点间的机率高。
