代数

Lie superalgebras are the generalization of Lie algebras, and they are closely related with physics.

李超代数是李代数的一种推广，这一数学概念有着很强的物理背景。

The sums may be from any one or combination of the following topics: pre-algebra, algebraic expressions, algebraic expansion (multiplication of binomials and trinomials), algebraic factors, simple equations,simultaneous equations and quadratic equations.

数学试题可能来自于下列主题之一或者其组合：学龄前数学，数学表达式，代数表达式，代数因数，简单等式，联立方程式和二次方程式。

Further picosecond PL studies on dendronized PFs show that the fluorene-based emission in dilute solution follows a single exponential decay, whereas those in thin film decayed in a multi-phase manner and the lifetime prolongs with the generation of dendronization. These observations are discussed in terms of dispersive transport happening between adjacent chains in film. The dispersive relaxation can be controlled by site isolation of bulky dendrons. Our results prove that dendronization is highly effective in controlling the inter-chain interactions of fluorene-based polymers.

不同代数树枝化聚芴的时间分辨荧光动力学研究结果表明，溶液状态下的发光为单指数衰减行为，而薄膜状态下的发光为多指数衰减行为，且其发光寿命随树枝化代数增加而增长，表明树枝化基团抑制了邻近的聚芴分子之间能量传递所致的激发态能量耗散。

Since that time, Boole's original conception has been extensively developed and refined by algebraists and logicians.

由于布尔代数，最初的概念逻辑学和二进制算术之间的内在联系，数，逻辑学和二进制算术之间的内在联系，使得布尔代数的理论在电子计算机的发展中起到举足轻重的作用。

Since that time,Boole's original concept has been extensively developed and refined by algebraists and logicians.

布尔代数的概念最初是有英国数学家George Boole于1847年提出来的，从那时起，代数学家和逻辑学家们更广泛的发展了Boole的这一其实概念，并使之更加精练。

As a matter of fact we develop our study in the more general and more natural context of a theory ~ internally defined with respect to a topos of sheaves on a frame (i.e. a complete Heyting algebra; for example the algebra of open subsets of a topological space).

作为一个事实上我们在发展中的一个理论更普遍，更自然的环境研究国内关于对一帧的捆一topos中定义的（即完全Heyting代数，例如以开放的子集代数拓扑空间）。

The algebra of quaternions, the first noncommutative algebra was thus suddenly born.

四元数的代数，第一非交换的代数，就这样在一夜之间诞生了。

The algebra of quaternions, the first noncommutative algebra was thus suddenly born

四元数的代数，第一非交换的代数，就这样突然诞生了。

In Part II , we introduce the definition of so called standard Kac-Moody algebra by using g-module, and prove that Serre relationis the defining relation of any standard Kac-Moody algebrag .

第二部分：我们利用-模引进所谓典范的Kac-Moody代数的定义，证明了Serre关系式是任意一个典范Kac-Moody代数g的生成元定义关系(定理2.2)。

Then, we point out that stratification algebras are not necessarily quasi-hereditary algebras.

利用这个结论，举例说明[CPS5，PS]中关于&拟遗传代数是可层化的代数&其逆不成立。

同时，论述了一体化管理体系构建中的几个主要问题，包括职业健康安全管理中的危险源辨识、风险评价和风险控制、顾客满意度的科学监测、法律、法规体系的完善、一体化管理体系与企业标准化体系的有机结合、统一的领导机构和工作机构、一体化的内部审核和管理评审。

Deepwater Taranaki is investigated for its petroleum potential, using all available seismic data tied to shallow-water wells.

运用与浅水井相关的现有全部震波探测数据考察了深海区塔拉纳基盆地的油藏前景。
