The latter is essentially derived from the geometric realization of Happels triangulated equivalence between stable module category of repetitive algebra and bounded derived category of finite dimensional algebra. In terms of this realization, we deduce that the Lie algebra realized by derived category of a finite dimensional algebra is isomorphic to the Lie algebra realized by stable module category of the corresponding repetitive algebra.

用平面图形来表达三维立体实物，或用一个投影图来表达三维立体实物，必须符合画法几何的投影理论要求。

For example, the roll elastic deformation breaks the statically determinate condition of roll system in duo mill, and this is the main reason of bearing longevity shortening and burning accident; in aluminium foil four-high mill roll system with a 1 mm gap, the ideal position kept by a 3 mm offset is out of effect, some phenomenon such as chock horizontal vibration, gyroscopic effect and micro dimensional dynamic cross happen in fact rolling process, abnormal super and partial load resulted by these is the main reason of the end thrust bearing accident; the thermal deformation of mill roll system accompanying the temperature raising not only changes the roller track age of rolling bearing, but also results a micro dimensional slow dynamic inverse cross that counteracts the gyroscopic effect in a degree.

如二辊高刚度轧机轧辊的弹性弯曲微尺度行为，破坏了辊系机构杆系的静定条件，成为轧机轴承短寿烧损的主要根源；铝箔四辊轧机只具有1mm的有隙辊系，凭借设置3mm偏移距和轧制力平衡产生的水平力以保持轧辊理想定位失去效用，却发生轴承座水平振动现象、陀螺效应和动态交叉微尺度行为，成为止推滚动轴承异常超偏载导致短寿烧损的主要根源；轧机辊系的伴随升温产生的热变形，不仅改变了滚动轴承滚道轮廓，还引起运动副内慢变动态反交叉微尺度行为，抵消陀螺效应的部分动态交叉角度。

Following work has been done In the first part, we use the two dimensional or 2＇-state Markov modulated deterministic process to approximate the actual arrival process and then model the ATM multiplexer as an two dimensional MMDP/D/1/K or 2＇-state MMDP/D/1/K queueing system respectively.

After inspecting the distribution configuration of skin pixels in various color spaces and the spectrum reflection features of human skin, the authors carry out the highlighted are a analysis on a critical two-dimensional plane instead of in a three-dimensional color space, which brings forth certain advantages: computation complexity is deduced, rates between eigenvalues are produced in stepwise PCA to detect automatically the existence of highlighted skin and estimate robustly the skin dichromatic reflection vectors.

通过考察肤色在各种不同彩色空间中的分布形态，以及对皮肤光谱反射特性的分析，采用关键的2维平面代替3维彩色空间进行高光分析。
