The first approximate solution for amplitude frequency response curve of the primary resonance of the system has hardening characteristic.

分析一次近似解、二次近似解的特点，指出系统主共振的一次近似解的幅频响应曲线表现为硬刚度特性；二次近似解的幅频响应曲线表现为软刚度特性。

We can put the same quantity of oil into the jet engine twice, one test on ordinary ground, and the other on ice ground. If the reading values on the spring mechanical counter will be the same at 2 times, then the spaces the heavy moves will be different.

在喷气发动机中放入同样多的燃油分别做2次试验，一次在普通地面上，一次在冰面上，如果2次试验中弹簧计力器的读数都一样，那么重物前进的距离是会不同的。

In in control of during royal president, he has had the stay away from home of brilliant wall street 3 times, it is the help appears on the market grandly, it is go canvassing wall street rebuilds the confidence of pair of royal mode, it is the market prise growth that brought more than 800 million dollar directly the 3rd more.

The light compensation point of remontant cultivar was lower than that of once flowering cultivar, and the light saturation point of two-crop cultivar was higher than that of once flowering cultivar.

二次花品种与一次花品种相比，具有较低的光补偿点和较高的光饱合点，说明二次花品种对光的要求范围较一次花品种广，具有更广泛的生态适应性。

Similarly, steaks and chops cook more evenly on high grill heat — and faster as well — if you become a human rotisserie and turn them not once or twice but as often as you can stand to, even dozens of times, every 15 or 30 seconds.

同样，如果你是手工烤制，翻转不只是一次两次的，而要在能忍受的范围内频繁翻动，几十次，每15到30秒一次翻动的话，在烤架的高温条件下排骨烤的会更均匀，并且更快。

2-4岁每天就餐时1.25ml，一天一次或是两次，4岁以上2.5ml每天就餐时一次或是两次。

In view of product quality of cross wedge rolling semifinished product of automotive power-shift box middle shaft which has heavy sectional shrinkage,numerical simulation and experimental method were adopted to analyze single wedge rolling and second wedge rolling method.

针对用楔横轧工艺生产具有大断面收缩率特点的汽车变速箱中间轴毛坯所存在的产品质量问题，利用数值模拟与实轧试验对汽车变速箱中间轴毛坯一次楔成形和二次楔成形进行了分析研究，发现采用一次楔成形方法加工汽车变速箱中间轴毛坯，轧件不易发生弯曲，中间断面收缩率最大处没有发生缩颈现象，心部质量也较二次楔成形好。

In view of product quality of cross wedge rolling semifinished product of automotive power-shift box middle shaft which has heavy sectional shrinkage, numerical simulation and experimental method were adopted to analyze single wedge rolling and second wedge rolling method. It is found out that contrast second wedge rolling, single wedge rolling will not make workpiece bend easily, and after rolling the workpiece has no neck shrinkage.
