不偏性

Aim at the shortage of vertically additive method by which we can't discuss forced oscillations of systems of partial functional differential equations,we directly use the oscillatory definition,Green's formula and boundary condition of homogeneous Neumann to change the oscillatory problem of solutions to a class of systems of quasilinear parabolic equations of neutral type into the problem of which functional differential inequality haven't eventually positive solution.

针对垂直相加法无法讨论泛函偏微分方程组的强迫振动性的不足，直接利用振动的定义、Green公式以及齐次Neumann边界条件把中立型抛物微分方程组的振动问题转化为泛函微分不等式不存在最终正解的问题，然后利用最终正解的定义及上下极限得到了在齐次Neumann边界条件下判别其所有解振动或全振动的充分条件。

The Bidiagonal matrix method for the simulation of distillation and catalytic distillation is developed. The bidiagonal matrix method is proved to be better in convergcnce and stability by compared with the tridiagonal matrix method.

在多组分精馏塔的稳态模拟计算中，三对角矩阵法具有占用计算机内存少，无需计算偏导数矩阵等优点，但对强非理想性体系有时计算不收敛。

It can also reduce the scope of log records to be analyzed and help to detect anormal log records. Time-line sequence is an important character of log records. Most secure events consist of multi-stages. They will be loged in different network devices or in different system logs. These records have a partial sequence in time and same values in some fileds.

时间上的顺序性是日志记录的重要特征，大多数黑客入侵行为都不是独立的，而是由多个阶段组成的，这在日志系统中的表现就是对于一次入侵行为会在不同的网络设备或不同的系统日志中进行记录，这些记录在时间上存在一个偏序关系，在某些属性域存在相同的值。

Stroke mechanisms are ariable in HI-infected patients, with a relatiely high incidence of asculitis and hypercoagulability.

HI感染患者的卒中机制不确定，血管炎和血液凝固性过高导致卒中发生率相对偏高。

While dated, many scholars prefer it to timelier data from other agencies because it provides details of the very richest -- for example, the top 0.1% and the top 1%, not just the top 10%-- and includes capital gains, an important, though volatile, source of income for the affluent.

这一数据虽然偏旧，但它却比其他机构提供的时效性更好的数据更受许多学者的偏爱，因为它提供了反映美国富豪收入情况的细节性材料，比如明确列出了美国最富有的0.1%和1%人口的财富占有情况，而不是仅笼统介绍富裕程度在前10%那部分人的情况。此外，这一数据还包括资本利得指标，这一收入虽然波动性很大，但却是美国富人的一项重要财富来源。

The main characters of new cotton hybrid JiH239 were analysed based on the results of Hebei Cotton Regional Test in 2003~2004. The results showed that JiH239 was high yield, disease-resistance and fiber length and strength were better than CK cultivar, micronaire value was a little high. The Bt toxic protein gene expression levels was higher than bollworm-resistant CK Zhongmiansuo41 in different growing period. The purity of bollworm-resistant was higher than Zhongmiansuo41 in seeding period and no significant variety in bud period and flower-boll period.

笔者以2003~2004年河北省棉花品种区域试验结果为依据，分析了棉花新杂交种冀H239主要性状特征，结果表明，冀H239产量突出，抗病性强，纤维长度、纤维比强度优于对照，马克隆值偏高；苗期、蕾期、花期和铃期棉叶中Bt杀虫蛋白表达量、苗期抗性纯合度均高于抗虫对照品种中棉所41；蕾期和花铃期抗性纯合度与中棉所41差异不显著。

The seed purity of more than one hundred and thirty samples of six maizevarieties was assayed by using the three testing methods: storage proteins electrophoresis,isozyme isoelectric focusing in acrylamide and examination at field plots. Some importantpoints can be concluded from analyses as spearman order rank correlation on the seedpurity data as follows:First, there were deviations of the real performances to those purities obtained from out or in laboratory testing, even from the examination at field plot that is a routine way. Second, the seed globulin and isozyme electrophoresis, both with characteristics of rapid, cost-effective, devoid of environmental effect and speed, showed consistent purity; while the field-testing gave a higher degree of purity on the high side of cost than that in-lab approaches. Third, a good consistent purity was observed in the field plot and seed globulin testing, whereas inconsistency between field-testing and isozyme process. The last point is that seed globulin electrophoresis be a practical method apt to seed purity testing for maize.

并对130多份样品用三种检验方法(盐溶蛋白电泳、同功酶等电聚焦电泳和田间小区)检测的种子纯度数据作排序相关等统计分析，得到如下结果：室内外检测方法都会与种子真实状况有一定差异，田间种植鉴定与真实情况符合性并不一定最好；盐溶蛋白与同功酶等电聚焦这两种方法检测种子纯度所需时间短，成本低，不受外界环境限制，出结果快，二者的结果没有太大差异；田间种植鉴定成本较高，检测的结果普遍偏高；等电聚焦电泳与田间鉴定的一致性年度间存在差异，而盐溶蛋白凝胶电泳法与田间鉴定的一致性较高；种子盐溶蛋白凝胶电泳法较适于鉴定玉米种子纯度。
