The two regulations supporting each other, the code adhere to a positive advocate, focusing on morality is of Party members and Party leading cadres can see, enough to get a high standard。尺寸綜合試圖確定機構(gòu)的重要尺寸和起動位置，該機構(gòu)是為著實現(xiàn)規(guī)定的任務(wù)和預(yù)期的性能而事先設(shè)想的。定義的第二部分可用以下兩方面來解釋： ） (1) The study of methods of creating a given motion by means of mechanisms (2) The study of methods of creating mechanisms having a given motion. In either version, the motion is given and the mechanism is to be found. This is the essence of kinematic synthesis. Thus kinematic synthesis deals with the systematic design of mechanisms for a given performance. The area of synthesis may be grouped into two categories. 1．研究借助機構(gòu)來產(chǎn)生給定運動的方法 2．研究建造能產(chǎn)生給定運動機構(gòu)的方法 在兩個方案中，運動是給定的而機構(gòu)是創(chuàng)建的。典型的機構(gòu)要設(shè)計成使剛性構(gòu)件相對基準(zhǔn)構(gòu)件產(chǎn)生所希望的運動。在機構(gòu)運 動期間，傳動角的值在改變。其輸入和輸出都可以作整周轉(zhuǎn)動或者轉(zhuǎn)換成稱作反平行四邊形機構(gòu)的交叉結(jié)構(gòu)。換句話說，機構(gòu)是允許其 “ 剛性構(gòu)件 ” 之間相對運動，而結(jié)構(gòu)則不能。 24. The ultrasonic machining process is applied to both conducting and nonconducting material, and relies entirely upon abrasive action for metal removal. 超聲波加工工藝既應(yīng)用于導(dǎo)體材料，也用于非導(dǎo)體材料，并且完全依賴于磨損作用進行金屬切削。 16. Chemical milling is controlled etching process using strong alkaline or acid etchants. Aluminum, titanium, magnesium, and steel are the principal metals processed by this method. 化學(xué)蝕刻，通過使用強堿或強酸蝕刻劑來控制蝕刻過程，鋁，鈦，鎂和鋼是用這種方法處理的主要金屬。 5. Although there are many tooth shapes possible in which a mating tooth could be designed to satisfy the fundamental law, only two are in general use: the cycloidal and involute profiles. 雖然可以設(shè)計出有很多 齒廓來滿足傳動裝置的基本定律，但通常所使用的只有兩種：即擺線齒廓和漸開線齒廓。 ) 3. The process of drawing kinematic diagrams and determining degrees of freedom of mechanisms are the first steps in both the kinematic analysis and synthesis process.（ 畫運動圖和確定機構(gòu)自由度的過程，就是運動分析和綜合過程的第一個階段。但是我們還看到，這些連桿機構(gòu)其性能水平的發(fā)揮已經(jīng)受到限制。 譯文 P40 [2] 4． Any two mating tooth profiles that satisfy the fundamental law of gearing are called conjugate profiles. 任何滿足齒輪傳動基本定律的一對相互嚙合齒廓稱之為共軛齒廓。 15. Upright drilling machines or drill presses are available in a variety of sizes and types, and are equipped with a sufficient range of spindle speeds and automatic feeds to fit the needs of most industries. 立式鉆床或鉆孔壓力機，具有各種各樣的尺寸和類型，為了適合大多數(shù)工業(yè)的需求，這些機床都裝配有充足的軸速范圍和自動進給量。 23. The problem of the specialist in mechanical design is not how to design a rolling bearing but, rather, how to select one. 在機械設(shè)計中，專家所面臨的問題，不是如何設(shè)計軸承，而是如何挑選軸承。這樣的運動鏈在至少有一個構(gòu)件被固定的條件下：（ 1）如果 至少有兩個構(gòu)件能保持運動，就變?yōu)?機構(gòu)，（ 2）如果沒有一個構(gòu)件能夠運動，則就成為結(jié)構(gòu)。作為一個特例，在平行四桿機構(gòu)中，輸入桿的長度等于輸出桿的長度，連接桿的長度和固定桿（機架）的長度，也是相等的。為了分析低速運轉(zhuǎn)或為了易于獲得如何能使任一機構(gòu) “ 運轉(zhuǎn) ” 的指數(shù)，傳動角的概念是非常有用的。 ） 5. Mechanisms form the basic geometrical elements of many mechanical devices including automatic packaging machinery, typewriters, mechanical toys, textile machinery, and others. A mechanism typically is designed to create a desired motion of a rigid body relative to a reference member. Kinematic design, or kinematic syntheses, of mechanisms often is the first step in the design of a plete machine. When forces are considered, the additional problems of dynamics, bearing loads, stresses, lubrication, and the like are introduced, and the larger problem bees one of machine design. （ 機構(gòu)是形成許多機械裝置的基本幾何結(jié)構(gòu)單元，這些機械裝置包括自動包裝機、打印機、機械玩具、紡織機械和其他機械等。目的是要找出位移、速度、加速度、沖擊或跳動（二 次 加速度），和可能發(fā)生的各構(gòu)件的高階加速度以及所描述徑跡和由某些構(gòu)件來實現(xiàn)的運動。運動綜合的第二個主要類型是通過目標(biāo)法來確定的最佳方法。為了保持恒定的角速度，各個齒輪齒廓必須服從齒輪嚙合
