The result show, pH of solution, the type and concentration of surface-active agent all have marked effect, pH change can transform the disperse behavior of attapulgite particle by altering granularity distributing in different range, influencing double electromotive force between particle and solution.

研究表明，水溶液的pH值、表面活性剂的类型和浓度对凹土的分散稳定性皆有显著的影响，pH值的变化改变了不同粒径范围的粒子总量分布，改变粒子与溶液间双电层电动势，从而改变凹土粒子的分散行为：由于凹土作为带电粒子在极性溶剂中容易达到物理分散的目的，因此，凹土在极性溶剂中的分散状况大大优于在非极性溶剂中的分散。

The floral primordium is initially circular, along with the edge of which slight concaves occur. The outmost whorl of tepal primordia arises as a result of apical meristem division and the floral primordium then is in the shape of triangle. Two further whorls of tepal primordia arise in spiral acropetal sequence and are alternately arranged. When the innermost whorl of tepal primordia is at the late developmental stage, the foremost stamen primordia arise almost simultaneously in spiral acropetal succession and all of the stamen primordia are ultimately arranged in a triangle-cone form. Late in stamen primordium development, carpel primordia arise as same as the young stamen primordia and grow laterally. Grooves are present on the adaxial side of each carpel and develop into ventral sutures gradually closing up.

观光木的花原基最初为近圆形，随着顶端分生组织的活动，花原基边缘处出现浅凹，形成第一轮花被片原基，此时，花原基呈三角形排列，后两轮花被片原基依次发生，与前一轮互生；在内轮花被片发生的后期，最初几枚雄蕊原基几乎同时出现，呈螺旋状向顶发生，最后排列成三角圆锥状；雄蕊原基发育后期，心皮原基开始发育，形状与发育初期的雄蕊原基相似，随后心皮原基进行侧向生长，在近轴面出现浅凹，进而发育为凹槽，形成腹缝线，最后腹缝线完全愈合。

The changing rule of the deformed zone and non-deformed zone in the process of bending the vee parts is analyzed.

分析了V形件弯曲过程中变形区与非变形区的变化规律，建立了计算凹模最小深度的公式，并通过数值实例，讨论了工件尺寸与凹模圆角半径对弯曲凹模最小深度的影响。

And I must not forget, that we had in the Ship a Dog and two Cats, of whose eminent History I may have occasion to say something in its place; for I carry'd both the Cats with me, and as for the Dog, he jump'd out of the Ship of himself and swam on Shore to me the Day after I went on Shore with my first Cargo, and was a trusty Servant to me many Years; I wanted nothing that he could fetch me, nor any Company that he could make up to me, I only wanted to have him talk to me, but that would not do: As I observ'd before, I found Pen, Ink and Paper, and I husbanded them to the utmost, and I shall shew, that while my Ink lasted, I kept things very exact, but after that was gone I could not, for I could not make any Ink by any Means that I could devise.

我把柱子做成一个大十字架，立在我第一次上岸的地方。在这方柱的四边，我每天用刀刻一个凹口，每七天刻一个长一倍的凹口，每一月刻一个再长一倍的凹口。就这样，我就有了一个日历，可以计算日月了。

In the standard designing procedure of stamping die , the calculation formulas of dimensions of both punch and die plate are derived based on such a principle that for blanking operation to produce the punch with the die plate as the basic part, and for the punching operation to produce the die plate with the punch as the basic part.
