The results show that the precooling time of the probe is shortened significantly with the help of the vapor liquid separator, and decreases with the driven pressure. With the helical coiled wire and the helical mesh, significant thermal Oscillation corresponding the density-wave is observed in the precooling time. The average heat transfer coefficient enhances 1.5 times with the mentioned heat transfer enhancement techniques, and the temperature of the 2.5 min cryoprobe surface can reach -160℃ in 17℃ brine within 10 min.

结果表明：使用了快速预冷汽液分离器后，探针预冷时间大大缩短，并随驱动压力增大而减小；加入螺旋丝和螺旋丝网后，在预冷阶段出现明显的热力振荡，并伴有密度波振荡，平均换热系数为原来的1.5倍，在17℃生理盐水中10min时2.5min探针表面温度最低可达－160℃，大大提高了探针的冷却性能。

With a wimpy set of Firestones wrapping the optional 17-inch wheels on our tester and fuel-saving electric power steering telling the front-driven wheels what to do, we weren't surprised to hear squeals of protest each time we entered a curve.

随着wimpy一套Firestones包装可选17英寸的车轮我们的测试和节省燃料的电动助力转向告诉前端驱动车轮该怎么做，我们并不感到意外地听到squeals每次抗议我们进入了一个曲线。

According to the principle and characteristic of the formation of standing wave, the authors have developed a standing wave demonstration tube, which consists of loudspeaker, sonic focusing vessel, organic glass and a little liquid driven by the high power DDS signal. The frequency and phase of the highly stabilized signal, which is produced by MCU, DDS, LPF, can be numerically adjusted.

根据驻波形成的原理及其特点，利用MCU，DDS，LPF等产生频率和相位可数控调节、频率稳定性较好的大功率DDS信号源，使用该功率信号驱动由扬声器、声波汇聚器、有机玻璃管和少量液体组成的驻波演示管。

These simulations focused on the major factors driving Cretaceous climate changes and the critical time periods of the climate change, and tested the internal and external forcing in the earth climate system and the feedback effects among various spheres of the earth system, thus providing us an understanding of the mechanism of greenhouse climate and an important scientific basis for projection of the future climate changes.

这些古气候模拟试验锁定在气候变化的关键时段和驱动因子、测试地球内外动力和地球各圈层反馈作用，可为认识温室气候的成因、探讨气候变化内在机制和预测未来气候提供重要的科学依据。
