In this paper, we use some algebraic geometry methods to study the construction of χ-invariant algebras of some linear corresponding moduli space of these systems. Moreover, we completely determine the stable and semistable locus of these systems.

本文，我们以代数几何中的一些方法来研究某些线性动力系统的χ-不变代数的构造，并给出这类系统的相应的参量空间的刻划，进一步，完全决定了这类系统的稳定点、半稳定点的轨迹。

When F is an algebraically closed field char F≠2, A is similar over F to an orthogonal matrix if and only if ( 1 ) the invariant factors of A aer self-reciprocal (2) the elementary divi sors of A of the form x...

According to the dichotomy pixel Spatial Modeler modeling tool used to calculate the vegetation coverage in mining, use of non-supervised classification of vegetation coverage on the mining area classification, coloring, and finally come to mine the vegetation coverage in 1990-2000 category map, quantitative description of the Shanxi Province, 10 years of vegetation cover change: The region coverage to low, medium and high-based, the proportion remained almost unchanged, a significant increase in very low coverage, high coverage significantly decline.

根据像元二分法利用的建模工具Spatial Modeler计算出矿区的植被覆盖度，利用非监督分类方法对矿区的植被覆盖度进行分类、赋色，最后得出矿1990-2000年的植被覆盖度分类图，定量的说明了山西省10年间的植被覆盖变化情况：全区覆盖度以低、中和中高为主，所占比例几乎保持不变，极低覆盖度有明显增加，高覆盖度有明显下降。

Altruist theories in evolutionary biology were contested by Amotz Zahavi, the inventor of the signal theory and its correlative, the handicap principle, based mainly on his observations of the Arabian Babbler, a bird commonly known for its surprising altruistic behaviours.
