vector analysis

average velocity is a vector quantity, in the same direction as the vector △s. 平均速度是矢量,它與矢量s的方向相同。

The spirit of vector analysis is to use symbols to represent physical or geometric quantities . 向量分析實質是用符號來代表物理量或幾何量。

Conversely, in many experiments it is possible to measure all the velocity vectors . 另一方面,在許多實驗中,所有的速度矢量都可以測定。

The scalar product of a vector with itself is the square of the magnitude of the vector . 一個矢量自身相乘的標積等于該矢量大小的平方。

If two vectors are associated with each other as a dot product, the result is a scalar . 如果兩個向量以標量積結合,其結果為一標量。

Occasionally we shall make use of the following decomposition of the displacement vector . 有時候,我們將利用位失量的下列分解式。

Use the vector dot product to find the obtuse angle between two diagonals of a cube . 用矢量點積求立方體的兩條對角線所夾的鈍角。

Polar vectors and axial vectors are distinguished by their inversion properties . 極矢量與軸矢量的區別在于它們的反演性質不同。

This construction is often called the parallelogram law of addition of vectors . 這種作圖法常被稱為矢量相加的平行四邊形法則。

It is interesting and enlightening to consider the derivative of a vector . 這對研究矢量的導數來說是重要的,而且富有啟發性。

A vector quantity is one whose direction as well as its magnitude is significant . 矢量是一個其方向和其大小同樣有意義的量。

The elements of the vector are the redundants which can be obtained by solving . 列向量的諸元素為多余的,可求解方程來得到。

For arrays this template is called a dope vector or information vector . 我們把這個屬性單元稱為數組的內情向量或信息向量。

Every vector can be resolved into covariant or into contravariant components . 每個矢量都可以分解成協變分量或逆變分量。

The magnitudes of the rectangular components of a vector are easily computed . 一個矢量的正交分量的大小是很容易計算的。

Two vector quantities which are equal need not have the same physical effect . 兩個相等的矢量并不一定有相同的物理效果。

The action of a pathogen and an insect vector changed the ecology of the rabbit . 病原體和昆蟲媒介改變了兔子的生態學。

A vector quantity is an entity with a magnitude and a direction in space . 矢量是空間中既具有大小又具有方向的量。

The dot product of a pseudovector and a vector is called a pseudoscalar . 一個贗矢量和一個矢量的標識稱為贗標量。
