赋值

To analyze the different locations of the intersection of a ray and a polygon quickly, a scheme of calculating the number for the intersection point is established based on the structure query language and the method of weighting each side of the polygon.

采用对多边形各边赋权值的方法，分析射线与多边形相交的不同情况，给出了使用结构化查询语言实现交点个数求解的快速解决方案。

This article founds synthetic indicator systems for sustainable development, which cover the economic system, the social system and the system of resources environments and include 33 variables. In this article two kinds of objective weight method: principal components analytic method and entropy value method have carried on assessment of indicator systems for sustainable development.

本文建立了涵盖经济、社会、资源环境三大系统包括33个变量指标的可持续发展综合评价指标体系，用主成分分析法和熵值法两种客观赋权法进行了各系统可持续发展能力变动趋势的测度。

A calculation method and calculation results that show that a new kind of shaped paraboloid antennas can produce a ringy radiation pattern is presented.

通过数值计算发现将抛物线绕通过焦点的非抛物线对称轴旋转而形成的赋形抛物面天线可产生环状的方向图主瓣(此主瓣指的是主瓣最大值处)。

Utilizequadratic form and Perron value of bottleneck matrices, we study how the algebraic connectivityof a weighted tree changes under shifting its branches and changing its edge s weights and obtainmore entire information about algebrai.

利用代数连通度的二次型形式和瓶颈矩阵的Perron值，我们研究了当迁移或改变分支和变动一些边的权重时树的代数连通度的变化，得到了比过去更多的关于赋权树的代数连通度的结论。

Earlier, in 1952, the idea of distinguishing reliabilities of formulas in the propo-sitional logic was proposed by Rosser and Turquette.

在王国俊教授提出的积分语义学理论的基础上，一些学者在赋值域是连续值的情形下展开了对公式真确度的讨论。

When a value is assigned to one member of the union, all other members become undefined.

当将一个值赋给 union 对象的一个成员的时候，其他所有都变为未定义的。

Columns not marked as nullable will automatically raise exceptions if you attempt to persist an instance with a null value.

如果你试图对没有被标为可空的列赋空值，将会自动抛出异常。

For example, the depth distribution of grain size from the Site U1326 shows clear excursions at depths of 5~8, 21~26, 50~123, 132~140, 167~180, 195~206 and 220~240 mbsf. They coincide with the potential occurrence of gas hydrate indicated by soupy/mousselike structures, loggingderived gas hydrate concentrations and the recovered samples of the gas hydrate bearing sand layers.

如在U1326站位海底以下5~8 m、21~26 m、50~123 m、132~140 m、167~180 m、195~206 m、220~240 m深度位置出现了沉积物粒度明显偏向粗粒的趋势，而这些位置正好对应于大多数特殊沉积构造出现的深度，也对应于水合物饱和度值相对较高的深度，并与一些实际钻取的赋含水合物的浊积沙层观察结果一致。

This statement should be used only inside a rule and assigns values to the return value of the rule.

这个语句只应在某个规则的内部使用，它将 values 赋为该规则的返回值。

The index system in model was set up according to post evaluation content system framework set up before, it endues index with numbers, and also changes the method before only thinking much of benefit in project post evaluation.

该模型指标体系根据前文建立的后评价内容体系结构进行设置，对各项指标各赋权值，改变了以往对工程项目评价只重视效益的做法。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
