The results show that the addition of certain manganese in high chromium cast iron leads to a re-partitioning of alloy elements between austenite and carbide and a dropping in equilibrium phase transformation temperature although it's inappreciable for the influence of manganese on mass fractions of every phase in this cast iron. There is about 87 percent ledeburite under thermodynamic equilibrium condition and 23 to 32 percent M7C3 type carbide under thermodynamic non-equilibrium condition in the microstructure of 3C-l5Cr-4Mn-0.75Si system high chromium cast iron. Furthermore, the improvement of austenite stability and hardenability of manganese alloyed high chromium cast iron may been expected because there is a substitution between manganese and chromium that has been suggested by thermodynamic calculations.

结果表明，锰虽然对高铬铸铁中的各相数量影响不大，但一定数量的锰存在促使合金元素在奥氏体和碳化物两相中的重新分配，并降低平衡相的转变温度；在平衡条件下3C-15Cr-4Mn-0.75Si系高铬铸铁中菜氏体数量约占87%，而非平衡条件下M7C3型碳化物数量在23%-32%之间，且奥氏体中锰铬互替现象保证了奥氏体的稳定性和加锰高铬铸铁的淬透性。

The thesis accounts for the complexity and indeterminism about slopes" stability by chaos and catastrophe theory,it also provides the advanced and credible nonlinear theory for the stability about the open cast side-slopes.

本文还对动力作用下露天矿边坡对可能产生的非线性特性进行了讨论，以混沌和突变理论分别进行了探讨，说明边坡稳定性研究的复杂性，不可预测性，也为边坡稳定性评价提供了更为先进和可靠的非线性理论。

Chen Huagang interview is the love and the couple's classmate Chen Huagang, as are the acquaintances, Meng Fei and easy evening to the north of the state after they are placed in Chen Huagang lived next door to the hotel during the day and no arrangement with a group of people on the go the shooting scene, the so-called entertainment, for they are no longer strangers, especially the arrival of so many people Meng Fei of the shock, rather like the Incognito Travel like a calm and low-key, clothing teacher holding a strange clothes to different sectors of the The actor put on, there are professional actors star guest cast extras, plus some foreign actors to help out, as well as a lot of mess of temporary workers, the whole scene very loud noise, a hair stylist for everyone busy finishing hair, comb End 1 let go to make-up artists that make-up, a short while the new shape on the pendulum in front of everybody, photographers tune the machine just waiting for the director gives the order ready to start shooting shortly after a small lens may be made of a big-name stars , recordist actor holding a microphone followed by Ins and Outs about non-stop rotation, maintaining order there are many on-site commander Hu He is also leader of even a small rise in addition to chain the producer co-ordination, etc., etc. Some people say that the continuity clerk It is a big dye vat, some people say that this is art, there do not know, and complex social stories, strange, space shuttle pro-Chen Huagang busy as other journalists came together in front of different actors to mention the 1000 all over the trivial issue, Yi Xi, and Meng Fei feel a little bored aside turn up in the surrounding crowd, emotional confusion has long cast of Cloud Nine, the two girls, again back to sunny days filled with happy mood bare a sweet smile!!!

陈华刚采访的是love和陈华刚夫妇的同班同学，因都是熟人，孟菲和易夕到北州后也被安排在陈华刚住的宾馆隔壁，白天没什么安排就随一群人去了拍摄现场，所谓的娱乐圈，对于她们已经不再陌生，特别是孟菲的到来让不少人为之一惊，仿似微服私访般平静和低调，服装老师拿着千奇百怪的衣裳给不同界别的演员换上，有专业演员明星特邀演员临时演员，加有国外的演员助阵，以及一大堆乱七八糟的临时工，整个场面相当吵闹喧哗，发型师忙碌的为大家整理发型，梳完一个就让去化妆师那化妆，不一会新的造型就摆在大家的面前，摄影师调着机器只等导演一声令下随时准备开机拍摄，小小的镜头也许不久后就造了一个大牌影星，录音师拿着话筒紧跟着演员前前后后左右不停转动，维持秩序的现场指挥者有很多甚至小小的领队也呼喝起来，除此之外锁链着监制统筹场记等等等等有人说它是一个大染缸，有人说这是艺术，还有就不知道了，错综复杂的社会故事，千奇百怪的时空穿梭，百忙之中陈华刚拥随着其它记者一起走到不同演员面前提着千遍一律的琐碎问题，易夕和孟菲觉得有些无聊抛开人群在周围转了起来，情感方面的困惑早就抛之九霄云外，两个女孩重又恢复到阳光灿烂的日子，满怀着快乐的心情露着甜蜜的笑！！！

Except for research and discuss on turning and milling gray cast iron under high cutting speed, only few studies about machining nodular cast iron and vermicular cast iron with PCBN tool were carried out, while the two materials are widely used in manufacturing, specially automobile, aviation and machine tool.
