1、exciting spirit, to , not up of urgency, and slow shall not of sense, and sat not of sense, moments has a lying sake thing, and sat with rules of procedure of the, and station with officer of momentum, keep a ran of drive, and Rob of consciousness, and race of momentum, and spell of courage, to fire

2、 as of passion input work. The only way to ensure the healthy development of the cause, did not live up to the Organizations trust and the porcelain people live up to expectations. (B) the practice of three Suns, requires that we adhere to the problem oriented, improving the effectiveness of Governm

3、ent. An idea that I have said many times, talking about issues is much more useful than the talk. Because the results are in the past, talking about there, but the problem is eternal, not free, ubiquitous, if not resolved, will never go away on their own, and then only by solving a problem, work in

4、order to move forward, before moving forward progress of society. Marxist philosophy tells us that catch to catch the nature of the problem, grab the contradiction to catch the main contradiction. This requires us not only to be good at resolving individual, specific issues, also to be good at looki

5、ng through the phenomenon of nature, found by accident law, so as to catch common, widespread problem. We some place and sector of comrade, work starting point is good of, wants to developed some policy, wants to help enterprise development, and for masses do points things, but is careless make a kn

7、ishful thinking, not focused on and city general planning phase convergence, Final conflict for planning land cannot be submitted for approval, the project cant fall, wasted time, energy and money. In addition, there are many comrades often complain about difficult, superiors know the problem instea

8、d of trying, often report to prepare funding conditions. In fact, if any conditions are prepared properly, who called that is not the same?, conversely, if you are really looking for the right reasons, there is a good solution, the Government will provide support in terms of manpower, material and f

9、inancial resources. Government agencies set is a science, departments does the difference between good and bad, the difference only work well. Can get the attention and support, the key achievements and contributions to the Department. We carry out Government work, do anything to stick to problem-or

10、iented, be sure to have clear links to, take practical measures to achieve real results. This requires that we must reach out before the decision, . Help, in order to help companies ride out the storm. Last month, the City Government carried out a steady growth and development of research, many comr

11、ades told me that, in the course of land, some farmers dont understand municipal government decisions, even plain, block construction. On this issue, we should not only see the appearance of land expropriation, but on the other hand, thought the masses why conflict? worried that without a job, there

12、 are still other worries? can then take specific measures to resolve it. For example, baic Changhe automobile new bases in the land acquisition process and for surrounding farmers making a special people Club sector statistics, finds out, and organizations develop the skills training, Government文件编号

Of course, for those who obey the law and regulations, irrational, strong-hold engineering, sales of building materials of the wrongful act, or to law and regulation, s

15、everely and quickly dealt with. There is also a problem, our superiors issued by various departments of various types of files, not mechanically copy, but based on actual Jingdezhen, and meet the markets opinion, carry through the spirit of purpose that is also exploring fresh experience. (C) the pr

16、actice of three Suns, requires that we adhere to the face of contradictions and difficulties, to take in the pioneer. The event is difficult to see as dare to play are the basic qualities of leading cadres, best test leaders spirit of play before the conflict difficult. XI put forward by General Sec

17、retary 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 say no. Strict is an advantage. But when overdone, it is easy to go to the other extreme cant play. Some leaders fear problems, come i

18、nto 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 or even big problems Said to small problems, problem as small no problem. In fact, such leaders will eventually lead to big trouble, this un

19、it 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; oral work assigned by the leadership not to do it, to wait for written instructions. Named about program, but cant play, afraid of respon

20、sibility. Because they dare not play, many gays believe in growing flowers and planting thorn less vulgar philosophy, without the principle of harmony, safe seats, mediocre, dawdle, found the problem is not raised, more reluctant to face up to and resolve, until small problems become big problems. P

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

22、 a dare to face difficult but, in the face of crisis can stand up, face the mistakes accountable. Especially in the face of disaster insurance mandates, not contrary to law and policy, cracked the difficult to decipher, hard, truth run down hard, this is the performance to take, is the ability to wo

23、rk is all about. Recently in promoting urban management system in the process of deepening reform, municipal Bureau of commerce market service center staff did not understand the policies, constantly appealing. , Business Bureau executive team in the face, but the problem is not due to take, all thr

24、ough the night, days and nights, door-to-door work, publicity explain policies, laws and regulations, and eventually succeeded in resolving the conflict, which is to take the reality show. Of course, if you want to do to take on the assumption that good play. Some cadres are afraid to play in the re

32、.1.2试验要平行测定两次，计算两次结果的平均值。如果两次结果之差小于平均值的20%，取平均值为试验值；如大于或等于20%，则本次试验作废，重新取样进行试验。7.2出具报告7.2.1根据委托信息、原始记录进行报告编制。7.2.2报告送审核人员进行审核、签字。7.2.3报告送批准人员进行审核、签字。7.2.4报告复印、盖章，进行存档。7.3数据处理规定7.3.1有效数字7.3.1.1（末）的概念：所谓（末）指的是任何一个数最末一位数字对应的单位量值。7.3.1.2有效数字：任何一个数通过位数截取都可得到一个近似数，该近似数的绝对误差的模小于0.5（末）时，从左边第一个非零数字算起，直到最末尾为止

33、的所有数字。7.3.2近似数运算7.3.2.1加、减运算参加加减运算时以各数中（末）最大的数为准，其余的数均比它多保留一位，多余位数舍去。计算结果的（末）应与参与运算的数中（末）最大的那个数相同。若计算尚需参与下一步运算，则可多保留一位。例如：18.3+1.4546+0.876=18.3+1.45+0.88=20.6320.6如是最后计算结果，取20.6；若尚需参与下一步运算，取20.63。7.3.2.2乘、除运算参与数的乘除运算时，以有效数字最少的数为准，其余的数均较之多保留一位。运算结果（积或商）的有效数字位数，应与参与运算的数中有效数字位数最少的那个数相同。若计算结果尚需参与下一步运算，

34、则有效数字可多取一位。例如： 1.1m0.3268 m0.10300 m =1.1 m0.327 m0.103 m =0.0370 m30.037 m3运算结果为0.037 m3。若需参与下一步运算，则取0.0370 m3。7.3.3数字修约确定数字的修约间隔k（1、2、5）和有效数字位数后按下列方法进行：修约间隔整数倍数的一系列（修约数的上一个至下一个即可）数中，最接近拟修约数的数则为修约数。如1.150001按0.1修约间隔（0.1表明k=1，及1位小数），相临修约数有：1.2、1.1，两数中1.2最接近1.150001,故1.2为修约数。如果修约间隔整数倍数的一系列数中，有连续两个数同等

35、地接近拟修约数，则两个数中只有为修约间隔偶数倍的数才是修约数。8. 测量不确定度8.1数学模型：确定被测量Qe与输入量m1、m0 的函数关系式： 式中 Qe针片状颗粒含量， m0试验用的集料总质量，g m1针片状颗粒的质量，g8.1.1测量的最佳值：测得m0=800.4g , m1 =32.0g , Qe4.0% 8.2方差与灵敏系数：8.2.1方差：根据前面已建立的数学模型得 U C2(Qe)=(Qe/m0)2U2(m0)+(Qe /m1)2U2(m1)8.2.2灵敏系数： Ci=f/xi 即： C1=C(m1)= Qe/m1=0.002 C2=C(m0)= Qe/m0 =-0.000058

36、.3 标准不确定度的计算：测量读数m0 、m1的标准不确定度 U2(m0), U2(m1)U2(m0)= |/KU2(m1) = |/K 允许误差 =0.1，均匀分布,包含因子 K=1/3则： U2(m2)=0.06，U2(m1) =0.068.4计算合成标准不确定度U C2(Qe)：U C2(Qe)=( Qe / m1)2U2(m1)+( Qe / m0)2U2(m0) 得：U C(Qe)= 0.000068.5扩展不确定度U： U=kUC(fcc)= 0.000128.6试验检测结果的不确定度报告： y=yU=4.0%0.000129. 原始记录表格见下页。江苏省交通科学研究院股份有限公司 第 9 页 共 11 页江苏省交通科学研究院股份有限公司 粗集料针片状颗粒含量试验（游标卡尺法）粗集料针片状颗粒含量试验记录表格编 号： ZY01-028-2010 序 号： 任务单号： 样品编号： 环境条件： 样品名称： 规格型号： 样品状态： 仪器设备名称、型号及编号： 游标卡尺 0-500 3110103 试验方法： T 0312-2005 岩性次数试样总质量（g）针片状颗粒质量（g）针片状颗粒含量（%）平均值（%）备注1212试验： 复核： 日期： 江苏省交通科学研究院股份有限公司 第 11 页 共 11 页
