Since the Forefathers of the Farm Owners Trained the Farm Hands for First Class Farms in the Fatherly Handling of Farm Live Stock, the Farm Owners Feel they should carry on with the Family Tradition of Training Farm Hands of First Class Farmers in the Fatherly Handling of Farm Live Stock Because they Believe it is the Basis of Good Fundamental Farm Management. Task: You have 60 seconds to count the number of times the 6th letter of the alphabet appears at the right paragraph. Are you ready? Go! 給你 60秒的時(shí)間數(shù)出右邊段落中第六個(gè)字母的出現(xiàn)次數(shù) .

Scientific and objective method of analyzing the validity of a measurement system 一種科學(xué)客觀的方法，用于有效的分析測量系統(tǒng) –A “tool” which quantifies: 一種工具，它量化： 1. Equipment Variation 設(shè)備波動(dòng) 2. Appraiser (Operator) Variation 評估者波動(dòng) 3. The Total Variation of a Measurement System 測量系統(tǒng)總的波動(dòng) –MSA is NOT just Calibration 測量系統(tǒng)分析不僅僅是校準(zhǔn) Measurement System Analysis is often a “project within a project” 測量系統(tǒng)分析經(jīng)常是 ”項(xiàng)目中的項(xiàng)目 ” Main Sources Of Variation ?Materials 材料 ?Methods 方法 ?Machines 機(jī)器 ?People 人員 ?Environment 環(huán)境 ?Measures 測量 Measurement systems are the most neglected 測量系統(tǒng)經(jīng)常被忽視 測量系統(tǒng)：是用來對被測特性定量測量或定性評價(jià)的儀器或量具、標(biāo)準(zhǔn)、操作、方法、夾具、軟件、人員、環(huán)境和假設(shè)的集合；用來獲得測量結(jié)果的整個(gè)過程。 (MSA手冊第三版定義 ) Measurement System As A Process Cleanliness Temperature Dimension Weight Corrosion Hardness Conductivity Density Sequence Timing Positioning Location Setup Preparation Cleanliness Temperature Design Precision Calibration Resolution Stability Wear Cleanliness Vibration Atmospheric pressure Lighting Temperature Humidity Complianceprocedure Fatigue Attention Calculation error Interpretation Speed Coordination Vision Knowledgeinstrument Dexterity People Environment Measurement Error Method Material Machine Components Of Measurement Error ?
