Mechanics course mainly includes the description of movement of objects , the instantaneous effect of strength , spatial build - up effect of strength , temporal build - up effect of strength , nonindividual body mechanics , mechanical wave and sound , relativity , inalterability and covariability and mechanics foundation of the theory of relativity 力學主要內容包括物體運動的描述,力的瞬時效應,力的空間累積效應,力的時間累積效應,連續體力學,機械波和聲,相對性、不變性與協變性和相對論力學基礎等。

Combining kinematics , body mechanics and medical knowledge into the product development and design , and employing specialized , humanized and rational design conception and strict production test standards , we manufacture each product seriously 并結合運動學、人體力學和醫學的基礎上進行開發和設計,以專業化、人性化、合理化的設計思路和嚴格的產品檢驗標準對待每一件產品。

There are also body culture development exercises similar to chi gung which help develop the correct body mechanics for close quarter fighting 也有類似氣功的體內文明開發練習,幫助發展適用于近身格斗的身體技能。

Poor body mechanics , prolonged activity , repetitive motions , and fatigue are major contributors to these injuries 導致這些傷痛的原因包括不正確的身體運動、長時間活動、持續行活動以及過度疲勞。
