Example Sentences:

	1.	For a long time , mathematic method is used in the research of the crossing number of graph . however , if the graph is very big , the possible number of drawing will increase rapidly 长期以来，图的交叉数的研究主要采用纯数学方法，但随着所研究图的增大，可能的画法急剧增长，研究也越来越困难。
	2.	Based on calculation method on unfold size and piece form , theory analysis and research are given on ellipse , circle tube , box as equal - high , irregular , unequal - high , irregular piece , process and condition on possibility of drawing are introduced , through calculation coefficient , number of drawing , drawing testing dies are made , results are given , it is similar to calculation method , in the same time , complex drawing presswork is planed , to avoid wrinkle , critical in drawing process . in this paper , die designing is introduced based on complex drawing unfold size calculation , press center is automatic calculated , apartments of press tools are calculated too with material mechanic production process and press form are better , period of die designing is to reduced , and cost of product is lower 对基于复杂拉深件展开尺寸计算的模具设计也作了详细的论述，指出了现有复杂拉深件模具设计制造程序的不合理性，本文在复杂拉深件展开尺寸基础上自动生成冲裁中心、冲裁周长，运用材料力学中杆件强度及抗失稳条件，实现对冲压模具参数的自动计算，简化了冲压模具弹性元件、打料装置的设计过程，给出了冲压模具结构设计流程，使得模具材料核算，制造过程，冲压方式更趋合理，缩短了模具设计制造周期，降低了产品生产成本。
	3.	Drawing piece unfold size is one basic condition under the calculation on coefficient , number of drawing , handbooks or books of press are not given , practice press production , die designer designs drawing die by experience calculation , after testing , according to deformation , state , defect shape of testing blank , shape and unfold size is revising , finally , unfold size and shape of blank are determined , designing period is longer , cost of die and work piece is to raise , economic benefit is to reduce 拉深件展开尺寸是拉深可行性分析中计算拉深系数与拉深次数的前提条件，现有冲压手册或教材对于复杂拉深件的展开尺寸计算尚未论述。复杂拉深件的冲压生产中，模具设计者凭经验估计拉深可行性，设计制造拉深模进行反复试压，根据试压件的形变状态，缺陷形貌，制定坯料展开尺寸和形状，周期较长，因而生产成本高，经济效益不佳。
