The influencing factor analysis shows that the formability window obviously expands with the decreasing of the drawing ratio and the increasing of the normal anisotropical coefficient r -value and the die profile radius, but the effect of the hardening exponent n -value on formability window is not obvious.

而影响因素分析显示：随着拉深比降低、厚向异性系数增加和凹模圆角半径增大，成形窗口明显扩大； n 值增加，成形窗口虽然有所扩大，但是效果并不明显。

Sythesizing thevalence electron number, electronegativity and atomatic radius of the alloying element, thecharacteristic value may be fixed at 4.223 in Ti alloy, and which may be expressed as4.223=∑N_if_i+0.310△x / x_+0.551 △r / r_Ti

综合合金元素的价电子数、化学负电性和原子半径三个因素，钛合金中ω相形成的特征值可定为4.223，其表达式为 4.223=∑Nf_i+0.310Δx/x_+0.551Δr/r_Ti

Secondly, the model of the passengers forecast were studied. The corridor analytic method was proposed in the metropolis rail transit passenger flow forecast application, The traffic district for passengers forecast was raised, which is centered on the hub, circled with the radius of attrahent scope .The forecast model applying toestimating the volume of collecting and dispersing passenger generation and transfer passenger distribution are raised, the example proved that the models are reliability and practicable.Thirdly, the plan theories of metropolitan rail transit were studied.

研究了都市圈城际轨道交通客流预测的方法；提出了走廊分析法在都市圈城际轨道交通客流预测中的应用，提出了以枢纽节点为中心、以吸引范围为半径的圆形范围为客流预测的虚拟交通小区的划分方法；并依此在确定吸引范围的基础上，提出了基于效用矩阵的都市圈轨道交通客流预测模型，实例分析证明该方法具有较强的实用性和可靠性。

This paper makes the optimum autofrettage analysis of thick-walled cylinder of the material with different yield strength in tension and compression base on the Mohr's yield criterion.

本文运用莫尔屈服准则对承受内压的拉压屈服强度不同材料的厚壁圆筒进行了自增强分析，得到了依赖于材料拉压比的厚壁圆筒的最佳弹塑性界面半径、最佳自增强内压。

The welding distortions of the diaphragm with coroneted blades in steam turbine have been studied with model and production experiments in this thesis. It is a main purpose to find out the rule of welding distortion of the diaphragm in radial, circumferential and axal direction.

为了掌握蒸汽轮机自带冠靜叶隔板焊接产生的直径变形、半径变形、节圆收缩率和倾斜变形的基本规律、提出减小和调整焊接变形的合理工艺措施，本文通过基于正交设计的模型试验和现场监测对自带冠靜叶隔板的焊接变形进行了研究。

The fine screen installation shall incorporate a radius edge at the pump bellmouth for smooth entry into the pump inlet.

好的荧屏安装将合并一在泵 bellmouth 的半径边缘为平滑的进入进入泵插入物之内。

The bigger average pore of the porosity system,the smaller size of the micro-residual oil droplet and the more dispersed micro-residual oil droplet after waterflooding, that is to say, when the average pore width is big enough,the micro-residual oil is mainly composed of isolated single-pore and dual-pores droplets whereas the blocklike remaining oil is hardly exist.

微观驱替效率随平均孔宽的增加而增加，孔隙大小决定微观剩余油液滴的大小，孔隙系统的平均孔隙半径越大，水驱之后微观剩余油的尺寸越小，分布越分散，也即当孔隙的平均孔宽较大时，微观剩余油主要是由孤立的单孔隙和双孔隙液滴组成，连片的块状剩余油几乎不存在。

The Caloris Basin is a notable landmark, a giant crater having a 650 km radius and is similar to the lunar basins.

该Caloris盆地是一个重要里程碑，一个巨大的陨石坑有一个650公里的半径，它类似于月球盆地。

Its most impressive feature is perhaps the 800-mi (1,300-km) Caloris Basin, formed by a huge meteorite impact.

它的表面布满陨星坑，给人印象最深刻的也许是它半径达1，300千米的卡路里盆地，是由一个巨大的陨石撞击而成。
