作为差分偏序集无界推广的差分集，我们研究了它的张量积问题，证明了任何消去差分集和布尔代数的张量积一定存在。

The difference between the test groups and the control group was statistically significant. It could be deduced that all the insecticides tested in this experiment damaged the spiders′ intestinal mucosa, compromising its function as a barrier and letting large molecules such as FTIC-D more easily penetrate. Among the insecticides, pyrethrin and Bt preparation are bio-insecticides, and the FITC-D concentrations of the spiders exposed to these two bio-insecticides were more than those of the spiders exposed to the chemical insecticides imidacloprid and dipterex. The difference between the bio-insecticide groups and the imidacloprid group was significant, but there was no significant difference between the bio-insecticide groups and the dipterex group.

结果表明：4种杀虫剂处理后拟环纹豹蛛血液中的荧光素浓度远高于对照组，各个处理组拟环纹豹蛛血液样本中的荧光素浓度均与对照组存在极显著差异，可见4种杀虫剂均将对拟环纹豹蛛肠黏膜的屏障功能造成损伤，导致大分子物质易于通过；其中1.5%除虫菊素水乳剂三保奇花和Bt制剂强杀处理后拟环纹豹蛛中肠黏膜的通透性高于仿烟碱类化学杀虫剂吡虫啉处理组，差异达到显著水平，但与有机磷杀虫剂敌百虫处理组差异不显著。

According to market investigation, as to many weak points in the use of common oscilloscopes at present, the design of our products (VD252/422/252/622M) adopts the computer mouse to control the measurement positions of parameters and uses such functional switch as voltage level difference, time difference and reciprocal of time difference.

根据市场调查，针对目前的通用示波器使用中的诸多不足之处，我产品（VD252/422/522/622M）设计采用电脑的鼠标控制电参数的测量位置和电平电压差、时间差、时间差的倒数等功能切换。

by applying psychological measurement methods, the author compared volition quality between short track speed skaters with difference sports performances and genders in order to gain an insight into if there is a difference in volition quality between them, and revealed the following findings: in terms of objective clearness male skaters at international master sportsman level are superior to male skaters at national master sportsman level, but in terms of renitency male skaters at national master sportsman level are superior to male skaters at international master sportsman level; female skaters at national master sportsman level are superior to level 1 female skaters in terms of renitency, determination, confidence and total score, and differences between them are significant; furthermore, by comparing volition quality between male and female skaters, the author found that in terms of toughness male skaters are superior to female skaters, and the difference is significant, but in terms of other 5 factors and total score, differences between them are not significant.

In the view of ability difference, this paper studies the asymmetric mechanism of collusion-proof, and proves that: when ability difference is symmetric information, collusion stake can be distributed on this common information, thus ability difference cannot result in server benefit conflict between agents to make the coalition c...

本文在强调代理人能力差异的基础上，建立防止合谋的非对称机制。并证明当能力差异为公共信息时，合谋收益就可以据此公共信息进行分配，因此双方的能力差异并不足以使代理人之间产生严重的利益冲突并导致利益集团的崩溃，从而无法防止合谋的发生

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
