Angles are measured clockwise when looking along the rotation axis toward the origin 角度按照沿旋轉(zhuǎn)軸向原點(diǎn)方向看的順時(shí)針方向測量。
Material along the rotation axis falls vertically toward the equatorial plane much faster 沿著轉(zhuǎn)軸兩側(cè)分布的物質(zhì)則快速筆直地落入赤道面。
Angles are measured clockwise when viewed from the rotation axis positive side toward the origin 角度按照沿旋轉(zhuǎn)軸(正面)向原點(diǎn)方向看的順時(shí)針方向測量。
Place the 3dcursor at the position through which the rotation axis must pass . such an axis will be vertical 放置3d光標(biāo)在你要作為旋轉(zhuǎn)軸的位置,軸是垂直的。
When swinging transmission machine operation , the force constant rotation axis to make efforts before and axial rotation move backward 當(dāng)搖擺傳動(dòng)機(jī)械運(yùn)行時(shí),等速旋轉(zhuǎn)入力軸使出力軸向前和向后旋動(dòng)。
For those who haven ' t heard the word , " precession " is when an object with a nonspherical shape wobbles around its rotation axis 如果你還不了解“進(jìn)動(dòng)”這個(gè)詞,進(jìn)動(dòng)指的是物體繞它的旋轉(zhuǎn)軸有非球形的擺動(dòng)。
Precessing stars do radiate gravitational waves , but they ' re not the only ones . any asymmetry about the rotation axis will do 進(jìn)動(dòng)的星體確實(shí)會(huì)輻射引力波,但它們并非唯一的選擇。繞旋轉(zhuǎn)軸的任何不對稱都會(huì)導(dǎo)致引力波的產(chǎn)生。
As the earth spins on its rotation axis , it wobbles like a top , slowly swinging the northern hemisphere closer to and then farther from the sun 當(dāng)?shù)厍蜃赞D(zhuǎn)時(shí),自轉(zhuǎn)軸會(huì)像陀螺一樣晃動(dòng),因此北半球與太陽的距離會(huì)逐漸接近,繼而遠(yuǎn)離。
Material in the equatorial region of the cloud ? that is , in the plane perpendicular to the rotation axis ? moves inward more and more slowly as rotation starts to balance the pull of gravity 當(dāng)轉(zhuǎn)動(dòng)開始與重力的向內(nèi)拉力平衡時(shí),位在整團(tuán)云氣的赤道區(qū)域,垂直于轉(zhuǎn)軸的平面上的物質(zhì),會(huì)逐漸減緩向內(nèi)移動(dòng)的速率。
Made in the rotation axis , dividing machinery to stop transmission . at this point , the operator may decide indexing products position , and began fabrication , assembly and testing needed for its action 在出力軸旋轉(zhuǎn)后,分度傳動(dòng)機(jī)械停止。此時(shí),操作者可決定分度產(chǎn)品的位置,并開始加工、裝配和檢驗(yàn),作其需要之動(dòng)作。
