函数元素

If for any two t-edge sequences whose initial edges have non-empty intersection, there exists an automorphism of H mapping one to the other, then H is called locally weakly t-transitive.

若对於任二个 t-线序列，其第一个元素的交集并非空集合时，均存在一个 H 的自同构函数将其中一个对应到另外一个，则 H 称为局部弱 t-递移。

Maintaining the Open List: This is actually one of the most time consuming elements of the A* pathfinding function.

维护开放列表：实际上这是A*寻路函数最耗费时间的元素之一。

Meyer, working independently, proposed the periodic law.

在现代，该法律规定的性能的元素的原子数周期函数。

D = SIZE, for M-by-N matrix X, returns the two-element row vector D = containing the number of rows and columns in the matrix.

如果函数仅用一个输出参量调用，就返回一个二元素的行，它包含行数和列数。

But in evaluating the self term of impedance elements, the separation of singular exact kernel is acceptable due to slowly convergence of series representations.

但在评价阻抗元素自身时，由于一系列表达式的缓慢收敛，确切奇异函数的分离也是可以的。

The research is about the reuse of urban sewage for virescence irrigation, and the influence of sewage irrigation on eco-environment such as soil, plant, etc. is studied. Under the condition of field sewage irrigation, the transport and transformation and accumulation mechanism of heavy metals, nutrients and organic pollutants as vaporizable hydroxybenzene etc. in the soil-plant system are analyzed. The heavy metal pollution is evaluated by the comprehensive pollution index. The spatial variability of heavy metals in sewage irrigation area is further understood. The spatial variability of heavy metals and physical and chemical properties of soil are reflected in a more straight way by the theory model of variance function curve based on the geographical information system.

在城市污水回用于绿化灌溉对土壤、植物等生态环境的影响研究中分析了大田条件下污灌对土壤-植物体系中重金属、养分及挥发酚等有机污染物迁移转化及富集机理，对重金属污染进行了综合污染指数评价，进一步了解了污灌区重金属分布的空间异质性，基于地理信息系统提出了变异函数曲线的理论模型，更直观地反映出了重金属元素与土壤理化参数的空间变异特征。

So, when the iterator is assigned the value returned by the end function, the vector has no more elements.

所以，当迭代分配由最终返回函数，向量的值没有更多的元素。

Function defined by vector that appends elements to the back of a vector.

由vector类型定义的成员函数，用于把元素追加到vector对象的尾部。

But Perl hasn't left us stranded with a string when only a pair of numbers will do. By using the getpwnam function and passing the username we get an array of information about that username from the passwd file. For use in chown you'll need the 2 and 3 elements of the array. AUTHOR: Luke Melia

虽然有这些不便之处，Perl 并没有让我们陷入困境，我们可以把用户名作为 getpwnam 函数的参数，获得一个数组，里面包含了用户名对应的 userid 和 groupid，分别对应着数组里的第二和第三个元素。

Excitation functions of neutron, proton and α particle emission prior to scission measured in the reactions 28 Si+ 164,167,170 Er→ 192,195,198 Pb are studied using an extensive fission diffusion model and it is found that the model can well describe the trend of particle multiplicities of Pb isotopes measured experimentally as a function of the bombarding energy,which indicates the existence of isotope effects in prescission particle emission.

用推广的裂变扩散模型研究了2 8Si+16 4，16 7，170 Er→192 ，195，198Pb反应中测量的断前中子、质子和α粒子多重性的激发函数。发现扩散模型能很好地拟合这些轻粒子多重性随裂变系统激发能和Pb同位素的变化趋势。表明断前粒子发射存在一个同位素效应。进而在一个考虑了裂变过程中摩擦效应的统计模型的框架内，在In和Er这两个元素的同位素链中，考察了同位素效应与裂变碎片质量不对称性和裂变系统尺度的关系。计算结果表明：同位素效应的存在不依赖于裂变系统的大小和不对称性。此外，当裂变系统具有高的中质比时，轻带电粒子发射将不再敏感于裂变延迟时间的长短，而中子发射则非常敏感。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
