查询词典 mechanical pencil

It is equal to abandoned this part of material of nib lost and sharpens the saw-dust lost with the wooden pencil in fact, Because in 95%, the lead clothing pencil the raw materials utilization ratios of it material-saving the wrapping up core lead part removes the space of blind hole part of filling in backs end of pencil stub that are taken up of post of handle of pencil, The plumbaginous clothing material sharpens the saw-dust equivalent of material lost to consume with the wooden pencil basically, The pencil utilization ratio of raw materials produced with the timber is in 30-35%, a finished product pencil can only use two-thirds in using, Back one-third is abandoned, so the material-saving pencil is still pencil province of material-saving raw materials compared with wooden pencil.

被弃掉的笔头这部分材料实际上是与木制铅笔削掉的木屑是相等的，因为，节材铅笔它的原材料利用率在95%，铅衣包铅芯部分除去铅笔柄柱塞所占的铅笔头后端的盲孔部分的空间，铅衣材料基本和木制铅笔削铅衣削掉的木屑材料等量耗费的，而用木材生产铅笔的原材料利用率在30%-35%，一支成品铅笔在使用中只能使用三分之二，后三分之一被弃掉，所以节材铅笔与木制铅笔相对比还是节材铅笔节省原材料。

At that time, some people say that you play with fire, also told the others, but you do not have to defend themselves, you want to become a "green" Guardian, but you did not tell you your thoughts, and later, you come up with the matchbook by others, pumping Opened, they found that there is full of pencil shavings, you find that the original class some students only pay attention to "throw Zhixie", often cut a pencil, the pencil shavings cut in the ground, the impact on the cleanliness of the classroom, therefore, you From the home with a matchbook, will be stuffed into a pencil litter box.

当时，有人说你玩火，还告诉别人，可是你没有为自己辩解，你想成为"环保卫士"，可是，你却没有告诉大家你的想法，后来，你的火柴盒被别人拿出来，抽开来看，却发现里面尽是铅笔屑，原来你发现班上有些同学只注意"不乱扔纸屑"，往往把削铅笔时的铅笔屑削在地上，影响了教室的整洁，于是，你就从家里带了一个火柴盒，将铅笔屑装进盒子里。

In this paper, two assemblies of special test equipments have been designed and fabricated by authors in our laboratory: namely Catalyst Molding Process Analyzer and Catalyst Mechanical Process Tester. These new skills are developed for the dynamic studies on whole mold forming process and crushing process of Fe-Cr WGHS catalyst pellet. Based on the orthogonal experimental design, the effects of some factors during the forming process of solid catalyst, such as predensification proportion, calcination time, calcination temperature and content of graphite on the mechanical strength of catalyst pellets are systematically examined, and the molding conditions have been optimized. Based on the experimental data, the relationship between catalyst density and forming pressure are educed, and the physical significances of some related parameters are described. The parameter of macro scopic elastic moduls has been suggested to character the mechanical properties of molding catalyst. The effects of molding pressure on mechanical properties of catalyst pellets are discussed, and results show that there exists a optimal molding pressure for the ideal mechanical properties: when over-high or over-low pressure is applied, the specific surface area and side crushing strength of catalyst pellets will decreased. The "rebound effect" will be undermined by the unsuitable pressure maintain process, resulting in the apparent decrease of mechanical strength of catalyst pellets.

本研究通过自行设计制造的催化剂模压成型过程分析仪（Catalyst Molding Process Analyzer， CMPA）和催化剂力学性质测试仪（Catalyst Mechanical Properties Tester， CMPT），以Fe-Cr系高温变换催化剂片剂为研究对象，对成型过程和受压破碎过程提供了全过程动态研究的新手段；本研究利用正交实验设计方法考察了固体催化剂成型过程中诸因素（包含预密致比例、煅烧时间、煅烧温度和石墨含量等）对催化剂成型体强度的影响，并对成型条件进行了优化；根据实验结果，关联确定了固体催化剂成型过程中的密度－压力关系式，并对方程中诸因子的物理意义进行了描述；提出了一种利用宏观弹性模量来表征成型催化剂的力学性质的方法；研究讨论了成型压力对催化剂成型体强度性质的影响，结果表明：对于催化剂成型体的强度和比表面性质，成型压力存在着一个最佳值，过高的成型压力会导致比表面积和侧压强度的降低；不适当的成型压力的维持时间会破坏&压力回弹&作用，造成催化剂成型体的机械强度明显降低。
