?快訊：牽手清華大學，鑄力國之重器

牽手清華大學，鑄力國之重器

遇見清華，始得芳華！

2018年10月初，三思泰捷與清華大學，就合作研制“陶瓷型殼/型芯材料數字化動態熱機械分析儀”達成共識，最終協議文本于日前簽署，這標志著繼中科院力學所之後，三思泰捷再次斬獲殊榮，全面進駐我國最高技術殿堂。

此次與三思泰捷合作的，是清華大學材料學院，柳百成院士所領導的課題組。

柳百成教授，中國工程院院士，材料科學家，我國材料加工工程與鑄造領域的權威專家，曾參與攻克長江三峽水電站所用的巨型水輪機轉輪的關鍵鑄造件。柳百成院士近年來研究重點是我國關鍵性共性技術，即關鍵技術材料、關鍵基礎零部件、先進基礎工藝與技術標准等。其中一個技術方向便是航空發動機關鍵技術。如我國國産大飛機C919所需的大型重型航空發動機所需的主要零部件溫合金葉片，進口價爲一公斤二十幾萬元。

柳百成院士

航空發動機，被譽爲“工業王冠上的明珠”“工業之花”，在國際上是被高度壟斷的絕密技術。其一個核心技術難點就在于發動機的高溫合金葉片。它需要滿足尺寸大、重量輕、耐高溫、強度高等相互沖突的技術要求。決定葉片成品率與成品質量的關鍵因素之一，就是用于空心氣冷合金葉片的複雜內腔陶瓷型芯。它是一個鑄造件，其鑄造技術一直是空心葉片鑄造中的瓶頸，決定著葉片的尺寸精度、合格率及鑄造成本。因此，不斷改進陶瓷型芯材料和制造技術就顯得十分重要。

此次双方要合作研发的，是“陶瓷型壳/型芯材料数字化动态热机械分析仪”，就是用于航空发动机高温合金空心叶片用陶瓷型芯的技术仿真模拟。该系统可以针对复杂多样的试验要求，结合力学、温度、材料、软件等多功能学科，适用于对金屬材料、非金屬材料、复合材料进行多功能力学模拟演示。该系统可以在常温、高温环境下，模拟金屬、非金屬、陶瓷及相关复合材料等实际工作中的受力情况，如拉伸、压缩、弯曲等，具有应力、应变、位移等多种闭环控制功能，配上相应的工装，可做拉伸、压缩、弯曲、剪切、撕裂、剥离、顶破、疲劳等试验。可自动求取最大试验力值、断裂力值、伸长率、抗拉强度、屈服强度、抗压强度、弹性模量、剪切强度、撕裂强度、剥离强度等参数。同时也可实现定伸长应力、定应力伸长、载荷保持等要求的测试。并能够通过计算机系统实时显示整个变化过程，并计算、存储、分析比较试验结果。

我司爲中科院力學所研制的超高溫材料試驗系統現場

我們祝願柳百成院士所領導的團隊，他們是我國大國重器的鍛造者，是我國科技大軍的先鋒隊和艱苦的技術跋涉者，正是因爲有了他們的辛勞，我們的大飛機才能從圖紙變爲現實，才能從地面一飛沖天。

三思泰捷，也必將全力以赴，忘我工作，伴隨著國家科技的前行腳步，沐浴榮光！

"And sure," she said, "and I hope that wretched old Feejee won't be in Japan at all, at all, and the horrid haythens won't roast him." THIRD-CLASS PASSENGERS. THIRD-CLASS PASSENGERS. I was about to put a false meaning even on that, when she added "We don't need the ford this time of year; let us ride back as if we gave up the trip--for there may be a vidette looking at us now in the edge of those bushes--and as soon as we get where we can't be seen let us take a circuit. We can cross the creek somewhere above and strike the Wiggins road up in the woods. You can find your way by the blessed stars, can't you--being the angel you are?" "Good-night, gentlemen," said the doctor at last. As he passed into the darkness Quinn bent a mock frown upon his young superior. It would require a mathematical diagram to describe the incident with absolute accuracy. The Curate, of course, had heard nothing about the Clockwork man's other performances; he had scarcely heeded the hints thrown out about the possibility of movement in other dimensions. It seemed to him, in the uncertain light of their surroundings, that the Clockwork man's right arm gradually disappeared into space. There was no arm there at all. Afterwards, he remembered a brief moment when the arm had begun to grow vague and transparent; it was moving very rapidly, in some direction, neither up nor down, nor this way or that, but along some shadowy plane. Then it went into nothing, evaporated from view. And just as suddenly, it swung back into the plane of the curate's vision, and the hand at the end of it grasped a silk hat. Good fitting is often not so much a question of skill as of the standard which a workman has fixed in his mind, and to which all that he does will more or less conform. If this standard is one of exactness and precision, all that is performed, whether it be filing, turning, planing, or drawing, will come to this standard. This faculty of mind can be defined no further than to say that it is an aversion to whatever is imperfect, and a love for what [171] is exact and precise. There is no faculty which has so much to do with success in mechanical pursuits, nor is there any trait more susceptible of cultivation. Methodical exactness, reasoning, and persistence are the powers which lead to proficiency in engineering pursuits. I was the only civilian in that road, and the soldiers, with much curiosity, stared at me. Whenever I noticed an officer, I gave an elaborate military salute, and with such an air that the officers, although hesitating at first, did not fail to return the salute. The reformed system of education was to be not only moral and religious but also severely scientific. The place given to mathematics as the foundation of a right intellectual training is most remarkable, and shows how truly Plato apprehended the conditions under which knowledge is acquired and enlarged. Here, as in other respects, he is, more even than Aristotle, the precursor of Auguste Comte. He arranges the mathematical sciences, so far as they then existed, in their logical order; and his remarks on the most general ideas suggested by astronomy read like a divination of rational mechanics. That a recommendation of such studies should be put into the mouth of Socrates is a striking incongruity. The older Plato grew the farther he seems to have advanced from the humanist to the naturalistic point of view; and, had he been willing to confess it, Hippias and Prodicus were the teachers with whom he finally found himself most in sympathy. We are told that when his end began to approach, the dying philosopher was pressed to choose a successor in the headship of the School. The manner in which he did this is289 characteristic of his singular gentleness and unwillingness to give offence. It was understood that the choice must lie between his two most distinguished pupils, Theophrastus of Lesbos, and Eudêmus of Rhodes. Aristotle asked for specimens of the wine grown in those islands. He first essayed the Rhodian vintage, and praised it highly, but remarked after tasting the other, ‘The Lesbian is sweeter,’ thus revealing his preference for Theophrastus, who accordingly reigned over the Lyceum in his stead.179 Abibulla saw them off with great deference and a contrite air, and watched their retreat; then, as[Pg 260] I was about to send him to despatch the message, he was indignant. The police! What could they do to a sahib like me? It was all very well to frighten poor folks—it was a sin to waste money in asking for a reply which I should never be called upon to show—and so he went on, till I made up my mind to think no more of the matter. And whenever I met the chief at the bazaar or by the Jellum, he only asked after my health and my amusements. Felipa shook her head at Ellton. "Don't get yourself excited about it, Jack dear," she soothed, and Ellton also tried to quiet him. The last straw was laid on when an Indian policeman arrested a young buck for some small offence. The buck tried to run away, and would not halt when he was told to. The chief of police fired and killed a squaw by mistake; and though he was properly sorry for it, and expressed his regret, the relatives and friends of the deceased squaw caught him a few days later, and cutting off his head, kicked it round, as they had seen the White-eye soldier do with his rubber foot-ball. Then they, aroused and afraid too of punishment, fled from the reservation and began to kill. "Yes," he assured her unmoved, "you are. At least you are going to do that, or go to jail." The poor man looked as miserable as if put in a strait-jacket, but tried to literally obey instructions. "Probably it was Corpril Elliott's good management," suggested Gid Mackall, whose hero-worship of Shorty grew apace. "I tell you there aint a trick o' soldierin' that he aint up to." Then suddenly she was silent—and Reuben kissed her. "You finish your tea," he said to George, "and bring some more, Maudie, for these gentlemen," nodding kindly to the two young men, who stared at him as if they thought he had taken leave of his senses.
