查询词典 wedge heel

If the observer is at a great distance compared to the other dimensions of the experiment and the rays are nearly perpendicular to the reflecting surfaces, then the path difference between the two waves (corresponding to r1-r2 in the preceding section) is just twice the thickness d of the air wedge at each point.

如果观察者比起实验装置来讲距离较远而且光线较接近于垂直反射于表面，那么这两光波的光程差(在前面所述的相应部分 r1-r2)就仅仅是空气劈尖在该点处的厚度 d 的两倍。

A large range of IRZ and intense fluctuating velocity area around the boundary of IRZ is measured and thought to be important to keep the excellent ignition and combustion characters of the new kind swirl burner. Together with temperature trace method, different structure and operation parameter of the burner are studied in this paper about their effects on turbulent and mixing characters of swirling jet. The structure variation includes different blade angle, use of central gear shape baffle, variable outer length and angle of lean primary air outlet, use of wedge outlet of lean primary air.

Results show that during the snowstorm disaster, under the large scale background with "trough in south and ridge in north", strong cold air caused by prevailing northerly wind in northern Asia wedged into low level atmosphere over Southeast China and formed a "clod cushion". At the same time, warm-wet air was also transported to Southeast China by southerly wind. The vertical shear of winds from cold to warm airflows produced strong upward motion and then, the warm-wet air over the cold air wedge was driven to rise. Finally, the structure of "warm cover" and "cold cushion", as well as corresponding vertical circulation over the converging frontal zone came into being.

研究结果表明，灾害发生期间，中国北方中低层大气盛行偏北气流，使较强的偏北冷空气"楔入"中国东南部低层大气，构成低层"冷垫"，同时偏南暖湿气流源源不断地将大量水汽输送到中国东南部，冷暖气流交汇及其垂直切变导致强烈的上升运动，构成了"冷垫"上空的"暖盖"及"南槽北脊"反位相环流汇合锋区的垂直环流结构。

Let us settle ourselves, and work and wedge our feet downward through the mud and slush of opinion, and prejudice, and tradition, and delusion, and appearance, that alluvion which covers the globe, through Paris and London, through New York and Boston and Concord, through Church and State, through poetry and philosophy and religion, till we come to a hard bottom and rocks in place, which we can call reality, and say, This is, and no mistake

观念、偏见、传统、妄想和表面现像组成的泥泞淤积层覆盖了整个地球，从巴黎到伦敦，从纽约到波士顿再到康科，从教会到政府，从诗学到哲学再到宗教，全部被覆盖着。我们要迈开双脚，踏着淤泥前进，一直到我们抵达我们称之为"现实"的实地和礁石为止。我们说，就是这个，没错。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
