The processing time and the acceleration due to gravity were the important factor affecting its growth.The appropriate treatment can promote plant growth.

结论］超重处理可以影响水稻幼苗的生长，处理时间以及重力加速度是影响其生长的重要因素，适当的超重处理可以促进植物生长。

If air resistance is neglected, and the speed of the object is measured over several short, consecutive intervals as it falls, the differences in the speed of the object can be used to determine the acceleration due to gravity.

如果忽略空气阻力，并在几个短暂、连续的时间间隔上测量物体的速度，就可以用物体速度的微分来计算重力加速度。

The purpose of this laboratory activity is to measure the acceleration due to gravity by measuring the time of fall of a "picket fence" dropped through a photogate.

本实验的目的是通过测量栅栏下落穿过光门的时间，来测量重力加速度。

The slope of the best fit line (coefficient "a2") is the acceleration due to gravity for the most recent run of data.

最佳拟合直线的斜率（系数"a2"）就是最近一次试验数据的重力加速度。

Is the acceleration due to gravity the same for both the 19 mm ball and the 13 mm ball?

19mm 小球和13mm 小球的重力加速度是否相同？

The component of the acceleration due to gravity which is parallel to the inclined surface is gsin 續 where 續 is the angle of the incline.

重力加速度平行于斜面的部分等于 gsin θ，这里的θ是斜面的倾角。

What is the percent difference between the measured value for the acceleration due to gravity and the accepted value (9.8 m/sec/sec)?

重力加速度的测量值与公认值(9.8 m/sec/sec)之间的差别百分比是多少？

That's an acceleration of gravity that might be somewhere on Earth's surface.

这是地球某处的重力加速度的值。

Return the acceleration of gravity in this system.

返回重力加速度的值。

Imagine a system with some unknown acceleration of gravity.

想象一下，这些不同的重力加速度对一个系统的影响吧。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
