查询词典 tread as if on thin ice -- to be very careful

The computation model of two-point contact (for cone-tread) and conformal contact (for worn-tread) resulting from wheel flange close to rail is firstly established in this paper. A detailed analysis is made of the wheel/rail contact force, contact status and wheel/rail stress distribution on the different action of tractive forces and transverse forces. We draw some important conclusions, one of which is that the locomotive adhesion performance will decrease with the increase of transverse forces between wheel and rail.

Aiming at this problem, the concept of the second order power spectrum was proposed based on the characteristic of the amplitude tune with periodical notch spectrum in thin layer and theoretically researched. The corresponding relationship between the thickness of thin layers and the maximum value of second order power spectrum was established. The theoretical criteria and method for the thickness estimation by second order power spectrum were given. The second order power spectrum map is made by the energy relationship between the thickness of thin layers and the second order power spectrum, and the time responding to strong energy on the map is the time of thin layer.

为此，从薄层振幅调谐具有周期性陷频谱特征出发，提出了二阶功率谱的概念，从理论上对薄层的二阶功率谱特征进行了研究，建立了薄层厚度与二阶功率谱极大值之间的对应关系，给出了利用二阶功率谱进行薄层厚度预测的理论依据和方法，即根据薄层厚度和二阶功率谱的能量关系制作二阶功率谱图，图上强能量团对应的时间即为薄层时间厚度。

We look at the strategy in China there are many ways because HSBC grows in Hong Kong and Shanghai banking cooperation, so we get a very long history yet, goes back 135 years we have been in the land of your country, several times, over that period of time, but it is terribly important for us it is a very important of the future, I am not say anything because our chairman doesnt say anything possible opportunity to try to impress people that how much you want to be here significant, what I find really fascinating because we have just been spending a lot of time just making research in the brands of China, degree our competitors brand in general, there is a tendency I think among the people of Chinese all think it is a developing country, from the marketing standpoint, brand standpoint, in actually fact, if you look at how Chinese brands behave, it is a very developed country, it behaves much more like France, or the UK, does like Brazil, or Malazia, you have heard how competitive this market places, there are lots of very very good products, very high quality products, lots of very well-excepted local brands have a long history, in fact, it not given one foreign brand comes in, we have history and understanding here, we are the new brand on the block if you like, we have to understand where our initial be in the very complicated very very competitive market place, there are a lot of banks, there are a lot of banks specialized particular sector of the market, they also move to grow become a lot of unbanked people in this country, so all of our present opportunities and my strategy were wave with those

说到我们中国的战略，我想应该有许多种不同的战略吧，因为汇丰在香港和上海都有分支。我们在中国有很悠久的历史，可以追溯到135年前，之后几番登陆中国，但我认为最重要的，还是汇丰未来在中国的发展，虽然我很想让大家知道我们在中国发展的迫切愿望，但我现在不能宣布任何的战略，是因为我们的主席还没有表态。在中国，我们对中国的品牌做过许多的调研工作，把我们的竞争对手分级，最让我感到震惊的，在中国有一种趋势就是，从市场的角度来看，品牌的角度来看，中国的民众都认为中国是一个发展中国家，而实际上，如果你观察一下中国的知名品牌是怎么样运行的，你就会发现更像一个发达国家。这样的品牌行为更像是在法国，在英国，在巴西，或是马来西亚，在中国，你会发现市场竞争也是那样的激烈，中国市场上有许多出色的商品，高质量的商品，有许多拥有悠久历史、具有独特影响力的知名品牌，实际上，任何一个外国的品牌、任何一个后进入者想挤进来，都不是容易的事情。虽然我们很早就和中国有渊源，但我们也可以说是一个新的市场进入者，我们必须在这个复杂而又竞争激烈的市场中找到我们的方向，中国市场上现在有许多的银行，还有许多专门服务于某一特定顾客群的银行，但我们的空间还很大，因为中国还有许多没有开发的处女地，所以，我认为我们现在的机会和战略是和那些竞争对手们在市场上共舞。
