Muskmelon discs taken at ripening stage were used by different concentrations of calcium nitrate (1, 3, 5 mmol/L) and various time (4, 8, 12, 16, 20, 24 h) in order to investigate related to maturation and consenescence physiological parameters.

为明确钙在调节网纹甜瓜果实成熟衰老中的生理作用，以网纹甜瓜果实圆片为材料，研究了不同浓度硝酸钙(1，3，5 mmol/L)处理4，8，12，16，20和24 h情况下，甜瓜果实成熟衰老相关生理指标的变化。

Muskmelon discs taken at ripening stage were treated with different concentrations of calcium nitrate 1, 3 and 5 mmoloL^(-1 and various time (4, 8, 12, 16, 20 and 24h) in order to investigate the fruit softness and the relative physiological parameters.

以网纹甜瓜果实圆片为材料，研究了不同浓度硝酸钙1， 3， 5mmolL^(-1处理4，8，12，16，20，24h情况下，甜瓜果实软化及其相关生理指标的变化。

Moreover, compared with 1 mmol/L and 3 mmol/L, 5 mmol/L treatment more significantly slowed down the maturation and consenescence process of muskmelon. Meanwhile, compared to the calcium nitrate treated for 4 h and 8 h, the discs treated for 12 h were more apparently promoted or inhibited based on above maturation and consenescence physiological parameters; however, with the prolonging of treated time to 24 h, the activities of POD, SOD and CAT dropped markedly, as well as the inhibition of synthesis of soluble protein, and the increased speed of electrical conductivity and LOX activity were reduced markedly.

与1 mmol/L和3 mmol/L的硝酸钙相比，5 mmol/L的硝酸钙处理更能显著延缓果实的衰老进程；与处理4 h和8 h相比，处理12 h硝酸钙对以上各成熟衰老指标的促进或抑制作用效果更加显著，但是随着处理时间的延长至处理24 h时，POD、SOD、CAT活性反而下降，对可溶性蛋白的合成、外渗电导率和LOX活性升高速度的抑制效应显著降低。

The principle of braking is simple: slowing an object by removing kinetic energy from it. Formula One cars have disc brakes (like most road-cars) with rotating discs being squeezed between two brake pads by the action of a hydraulic calliper.

煞车系统的目的很简单，将动能转移来减慢物体的速度。F1赛车使用碟盘刹车(就像大多数的市售车一样)，有转动的碟盘，以液压方式由卡钳推动两片煞车片夹压煞车碟来减速。

Formula One cars have disc brakes(like most road-cars) with rotating discs beingsqueezed between two brake pads by the action of a hydraulic calliper.

一级方程式赛车采用盘式制动器，通过液压活塞驱动制动盘两侧的制动块，使其加紧制动盘从而对车轮制动。

They house substantial brake discs and callipers which provide powerful, durable braking performance.

他们的房子大量制动盘和卡钳，提供强大，持久的制动性能。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
