With straightedge and compasses, divide a segment of a into 2 parts . 用直尺和圓規(guī)把線段a分成兩部分。
If the line segment represents a vector, its projections are called the components of the vector . 如果線段代表一個(gè)矢量,其投影就叫做矢量的分量。
Any continuous curve can be closely approximated by a series of small parabolic segments . 任一連續(xù)曲線可以借一系列很小的拋物線線段較精密地近似表示。
In addition, average angular information is taken from adjacent segments and the incident ion beam . 另外,可以從鄰近線段和入射離子束取得平均角度的信息。
His plan is to drop perpendiculars from each point of the curve upon two planes intersecting at right angles . 他的計(jì)劃是:從曲線的每個(gè)點(diǎn)處作線段垂直于兩個(gè)互相垂直的平面。
If you place unit segments end-to-end, you will eventually get a segment larger than any given segment . 如果你將單位線段一個(gè)接一個(gè)連接起來(lái),最終會(huì)得到一條線段,比已知線段都長(zhǎng)。
Into a sequence of connected line segments 中的各段曲線轉(zhuǎn)換成相連的線段序列。
