一、抽样方案 抽样是指从总体中随机抽取适量的样本以判断总体的过程。 抽样检验方法的分类，按样本的质量特性可分为计数抽样与计量抽样

为使产品不偏离设计，包装产品质量，就 要依靠过程的监控，即建立一个控制下的 生产系统才能保证符合设计质量要求的产 品有连续性和重现性

变异性 产品质量总是或多或少存在着差异 即波动性，也称变异性。 常用的数理统计方法有：排列图法、分层 法、直方图、调查表法、控制图法、直方 图法和相关图法

包装机械定义是：“完成全部或部分包装 过程的机器，包装过程 包括充填、裹包、封口等主要包装工序， 以及与其相关的前后工序，如清洗、堆码 和拆卸等

一、药品包装的有关法规 1988年国家颁发了ㄍ药品包装管理办法》 国家药品监督管理局1998年修订的《药品 生产质量管理规范》第九章生产管理对药 品的批包装作了明确的规定。 2001年2月全国人大常委会审议通过的 《中华人民共和国药品管理法(修订草 案)》的第六章为“药品包装的管理

We have seen that the work done by a force F on a particle is given by dw =. dr. If the work done by F, when the particle moves from any position TI to any position T2, can be expressed as, W12=fdr=-(V(r2)-V(1)=V-v2, (1) then we say that the force is conservative. In the above expression, the scalar

In this lecture we will look at some applications of Newton's second law, expressed in the different coordinate systems that were introduced in lectures D3-D5. Recall that Newton's second law F=ma, (1) is a vector equation which is valid for inertial observers. In general, we will be interested in determining the motion of a particle given

In lecture D2 we introduced the position velocity and acceleration vectors and referred them to a fixed cartesian coordinate system. While it is clear that the choice of coordinate system does not affect the final answer, we shall see that, in practical problems, the choice of a specific system may simplify the calculations considerably. In previous lectures, all the vectors at all points in the trajectory were expressed in the

一、生产安全 实现安全生产的最基本的条件，就是保证人和机 器设备在生产中的安全。 1.安全制度 主要的安全制度有：安全机构和安全网制度； 安全教育制度；安全检查制度；安全措施管理制 度；事故管理制度；动火制度；劳动防护用品管 理制度；登高作业安全制度；受压容器安全制度； 尘毒岗位安全制度

In this lecture we will look at some other common systems of coordinates. We will present polar coordinates in two dimensions and cylindrical and spherical coordinates in three dimensions. We shall see that these systems are particularly useful for certain classes of problems Like in the case of intrinsic coordinates presented in the previous lecture, the reference frame changes from point to point. However, for the coordinate systems to be presented below, the reference frame depends only on the position of the particle. This is in contrast with the intrinsic coordinates, where the reference frame is a function of the position, as well as the path
