一般來說，碳硫聯(lián)測分析儀在碳、硫的連續(xù)測定中，難點是硫。這是因為：，鋼鐵中硫的含量比碳低得多，含量降低，測定越困難；第二，鋼鐵中硫化物（MnS、FeS）比想要的碳化物（Mn3Fe3C）熔點高，比較燃燒反應(yīng)的G值，這些硫化物的燃燒反應(yīng)比相應(yīng)的碳化物要困難的多；第三；比較燃燒后的產(chǎn)物，有副反應(yīng)發(fā)生，在一定條件下易轉(zhuǎn)化成三氧化硫，而二氧化碳無此現(xiàn)象。碳硫聯(lián)測分析儀時由于上述原因硫的測定比碳困難得多，而且測定的準(zhǔn)確度也差。
下面著重討論車刀幾何參數(shù)選擇原則。前角車刀前角的大小直接影響切削效果。前角選大些可減小切削變形、切削力，減少切削熱的產(chǎn)生，降低切削溫度，減小刀具刃口鈍圓半徑，使刀刃鋒利;同時能提高塑件加工質(zhì)量。但前角過大會削弱刀具強度，散熱條件變差，切削溫度反而升高，使刀具耐用度和塑件加工質(zhì)量下降。因此合理選擇刀具的前角很重要。選擇時應(yīng)綜合考慮塑件材料、刀具材料及加工性質(zhì)三方面的因素。實驗證明，加工塑件時，隨刀具前角的增大，切削阻力會減小。

九十五：什么是三視圖?答：常稱主視圖，俯視圖，左視圖三個基本視圖為三視圖。九十六：鉚工進(jìn)行裝配的三要素是什么?答：是支撐，定位，夾緊。九十七：什么是矯正?答：矯正就是將鋼材在外力作用下產(chǎn)生塑性變形，使鋼材局部收縮的纖維拉長，伸長的纖維縮短，達(dá)到金屬部分的纖維長度均勻，以消除表面不平，彎曲，扭曲和波浪變形的缺陷，從而獲得正確的形狀。九十八：三角形展開的原理是什么?答：原理是將零件表面分成一組或很多組三角形，然后求出各組三角形每邊的實長，并把它們的形狀依次畫在平面上，得到展開圖。

PLC
處理器(CPU)由控制器、運算器和寄存器組成并集成在一個芯片內(nèi)。CPU通過數(shù)據(jù)總線總線、地址總線、控制總線和電源總線與存儲器、輸入輸出接口、編程器和電源相連接。
小型PLC的CPU采用8位或16位微處理器或單片機，如8031、M68000等，這類芯片價格很低；中型PLC的CPU采用16位或32位微處理器或單片機，如8086、96系列單片機等，這類芯片主要特點是集成度高、運算速度快且可靠性高；而大型PLC則需采用高速位片式微處理器。
CPU按照PLC內(nèi)系統(tǒng)程序賦予的功能指揮PLC控制系統(tǒng)完成各項工作任務(wù)
