The feasibility of using mode converted waves (P to S and vice-versa at the top and bottom basalt interfaces) for sub-basalt imaging in Kutch region is discussed through a series of velocity-depth profiles.

通过一系列速度-深度剖面探讨了利用模式转换波(顶底玄武岩界面上的P波转化为S波或相反)对印度库奇地区玄武岩下成像的可行性。

Musical shows and entertainment celebrities have replaced the parades of armed and uniformed men marching in cadence or to a military band.

身穿制服的军人和着节奏或在军乐队伴奏下游行的活动已被精美的彩车。音乐表演以及娱乐界名人所替代。

Although the gathering was short, but the friendship lasts long , I believe under our common efforts, the technology among international tunnelers will be enhanced incessantly.

会议是短暂的，友谊是长存的，相信在我们大家的共同努力下，国际隧道界的技术将不断的提高。

In different conditions, the difference of whisker rotation、cavities evolution and whisker-pulling-out show the difference of grains boundary and interface sliding as well as the difference of capacity of dislocation to coordinate the two sort of slidings.

晶须转动、孔洞演化、晶须拔出等在不同条件下的差异实际上是晶界及界面滑动的差异以及位错对这两种滑动协调能力差异的反映。

The interest of the international progressive scene in us, especially in the States, the offer from Pain of Salvations' management Roasting House to promote our debut album and record the next one, and the opportunities to play abroad are things we have always been dreaming of, and they might give the impression that we are on the way of taking off. Nevertheless, we achieved all this with very small steps and we know there is a lot of work left to be done.

国际前卫乐界，尤其是美国，对我们感到兴趣，还有PoS经纪公司Roasting House为我们宣传首张专辑，并录制下张专辑，在国外做演出的机会(包括ProgPower Holland)，这一切都是我们梦昧以求的事，从这些现况看来很自然会让人觉得我们应该是开始起飞了，然而，我们却是经历非常缓慢的步伐才达到这些成果，我们很明白还有很多事等著我们去做。

Results show that chemical reaction between additives Al2O3 and Y2O3 accelerated the liquid phase sintering and the formation of the YAG non-crystalline,which was beneficial to improving fracture toughness of Cf/SiC composites.Higher sintering temperature resulted in the strongly bonded fiber/matrix interface.Fiber push-off,crack deflection and grains bridging are main toughening mechanisms of silicon carbide cera...

结果表明：烧结过程中，烧结助剂Al2O3、Y2O3之间发生化学反应，促进液相烧结，形成晶界间的次晶相YAG(3 Y2O3.5Al2O3)，有利于提高复合材料的断裂韧性；在较高烧结温度下，碳纤维、烧结助剂与基体间发生反应，形成较强结合界面；纤维拔出、裂纹偏转和晶粒桥联是碳化硅陶瓷的主要增韧机制。

It is well-acknowledged by many higher education administrators and researchers that the credit system is appropriate for the market economy and the whole social needs; credit system reform complies with the objective requirements of social and economic "development and that the research into China" s higher education credit system is not only an academic undergoing, but also a very important practical task.

我国高教界不少管理者和研究人员都认为，学分制是能适应市场经济乃至整个社会需求的一种教学管理制度；学分制改革是高等教育顺应社会经济发展的客观要求。在当前形势下，如何建立起符合我国国情的学分制教学管理制度，不但是一个重要的学术问题，而且是一个重大的实践课题。

In Fe-2.1% Cu alloys, copper-enriched phases precipitated at grain boundaries after water-quenched at 1600℃ and 1 000℃, and ε-Cu phases were found inside grains after water-quenched at 800℃.

Fe-2.1% Cu合金在1600℃和1000℃下淬火，含铜相都沿晶界析出；而800℃淬火ε-Cu相在晶内析出。
