一、填空题: 1、碳的质量分数的铁碳合金称之为铸铁,通常还含有较多的Mn、等元素。 2、优质碳素结构钢的钢号是以来表示的。 3、碳钢常规热处理有四种

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

制剂包装材料对于药品的稳定性和使用安全性有十分重要的影响，其选择是否合适，应当考虑以下因素： ①包装材料能够保护药品不受环境条件入空气、 光、湿度、温度、微生物的影响； ②包装材料与药品不能发生物理和化学反应； ③包装材料本身应无毒性；

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

一、药物制剂包装 药物制剂包装系指选用适宜的 材料和容器，利用一定技术对药物 制剂的成品进行分（罐）、封、壮、 贴签等加工过程的总称

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
