5、ies of leading cadres, best test leaders ' spirit of play before the conflict difficult. XI put forward by General Secretary of the cadres in five criteria had "to take". For a long time, there is a mentality in our cadres at all levels: afraid of problems. Of course, the inability to

6、say no. Strict is an advantage. But when overdone, it is easy to go to the other extreme can't play. Some leaders fear problems, come into conflict, walk around, do not do not solve the problem; once out of the problem, not to solve, but to do everything possible to avoid the question, problem o

7、r even big problems Said to small problems, problem as small no problem. In fact, such leaders will eventually lead to big trouble, this unit will eventually be the bigger problem. There is such a phenomenon, some comrades have already agreed not to implement, not to wait for minutes, a copy of form

Practice has proved that numerous small problems become difficult to pack in such a perfunctory questions, numerous projects were delayed waiting

10、 for, numerous development opportunities are lost in such a delay. As leading cadres must have a kind of still, smoke exits, in the face of contradiction on a dare to face difficult but, in the face of crisis can stand up, face the mistakes accountable.

20、驗(yàn)過(guò)程中，人員在儀器未關(guān)閉的情況下，禁止離開(kāi)；6.4試驗(yàn)完畢后，應(yīng)關(guān)閉儀器電源，下班后應(yīng)切斷總電源。7. 數(shù)據(jù)處理7.1試驗(yàn)結(jié)果計(jì)算7.1.1計(jì)算公式：按下式計(jì)算針片狀顆粒含量，準(zhǔn)確至0.1%。 式中 針片狀顆粒含量，； 試驗(yàn)用的集料總質(zhì)量，g；針片狀顆粒的質(zhì)量，g。7.1.2試驗(yàn)要平行測(cè)定兩次，計(jì)算兩次結(jié)果的平均值。如果兩次結(jié)果之差小于平均值的20%，取平均值為試驗(yàn)值；如大于或等于20%，則本次試驗(yàn)作廢，重新取樣進(jìn)行試驗(yàn)。7.2出具報(bào)告7.2.1根據(jù)委托信息、原始記錄進(jìn)行報(bào)告編制。7.2.2報(bào)告送審核人員進(jìn)行審核、簽字。7.2.3報(bào)告送批準(zhǔn)人員進(jìn)行審核、簽字。7.2.4報(bào)告復(fù)印、蓋章，進(jìn)行存

21、檔。7.3數(shù)據(jù)處理規(guī)定7.3.1有效數(shù)字7.3.1.1（末）的概念：所謂（末）指的是任何一個(gè)數(shù)最末一位數(shù)字對(duì)應(yīng)的單位量值。7.3.1.2有效數(shù)字：任何一個(gè)數(shù)通過(guò)位數(shù)截取都可得到一個(gè)近似數(shù)，該近似數(shù)的絕對(duì)誤差的模小于0.5（末）時(shí)，從左邊第一個(gè)非零數(shù)字算起，直到最末尾為止的所有數(shù)字。7.3.2近似數(shù)運(yùn)算7.3.2.1加、減運(yùn)算參加加減運(yùn)算時(shí)以各數(shù)中（末）最大的數(shù)為準(zhǔn)，其余的數(shù)均比它多保留一位，多余位數(shù)舍去。計(jì)算結(jié)果的（末）應(yīng)與參與運(yùn)算的數(shù)中（末）最大的那個(gè)數(shù)相同。若計(jì)算尚需參與下一步運(yùn)算，則可多保留一位。例如：18.3+1.4546+0.876=18.3+1.45+0.88=20.6320.6如

22、是最后計(jì)算結(jié)果，取20.6；若尚需參與下一步運(yùn)算，取20.63。7.3.2.2乘、除運(yùn)算參與數(shù)的乘除運(yùn)算時(shí)，以有效數(shù)字最少的數(shù)為準(zhǔn)，其余的數(shù)均較之多保留一位。運(yùn)算結(jié)果（積或商）的有效數(shù)字位數(shù)，應(yīng)與參與運(yùn)算的數(shù)中有效數(shù)字位數(shù)最少的那個(gè)數(shù)相同。若計(jì)算結(jié)果尚需參與下一步運(yùn)算，則有效數(shù)字可多取一位。例如： 1.1m×0.3268 m×0.10300 m =1.1 m×0.327 m×0.103 m =0.0370 m30.037 m3運(yùn)算結(jié)果為0.037 m3。若需參與下一步運(yùn)算，則取0.0370 m3。7.3.3數(shù)字修約確定數(shù)字的修約間隔k（1、2、5）和有效數(shù)字位數(shù)后按下列方法進(jìn)行：修約間隔整數(shù)倍數(shù)的一系列（修約數(shù)的上一個(gè)至下一個(gè)即可）數(shù)中，最接近擬修約數(shù)的數(shù)則為修約數(shù)。如1.150001按0.1修約間隔（0.1表明k=1，及1位小數(shù)），相臨修約數(shù)有：1.2、1.1，兩數(shù)中1.2最接近1.150001,故1.2為修約數(shù)。如果修約間隔整數(shù)倍數(shù)的一系列數(shù)中，有連續(xù)兩個(gè)數(shù)同等地接近擬修約數(shù)，則兩個(gè)數(shù)中只有為修約間隔偶數(shù)倍的數(shù)才是修約數(shù)。8. 測(cè)量不確定度8.1數(shù)學(xué)模型：確定被測(cè)量Qe與輸入量m1、m0 的函數(shù)關(guān)系式： 式中 Qe針片狀顆粒含量， m0試
