微弱

Over a 20-year period there was no increase in soil water content in the grazed grassland at depths of 2～9.9 m. There was a small increase(0.5～3.7 mm/a) in soil water content in the protected grassland, however the slow rate of increase suggests that at least 150 years would be needed for ungrazed grassland soils to regain water content similar to that present prior to planting trees. Recharge of deep soil moisture was faster in cropland(15 mm/a), but at this rate it would still take about 40 years to restore cropland soil water content to pre-plantation conditions.

结果表明，人工林死后的放牧荒坡在20a的时间里，其土壤水分没有补偿；人工林死后的保护草地土壤水分有微弱恢复迹象，但年恢复速度在0.5～3.7 mm之间，以这样的速度恢复到持续放牧荒坡的土壤含水量，至少需要150a以上；林后农地土壤含水量有恢复趋势，年平均恢复速度为15 mm左右，其土壤含水量要恢复到持续农地当前的水平，大约需要40a的时间。

Why the industrial products in modern China couldn't sell well on foreign market was because its poor quality, bad style, and unstandardized etc, and them its competitive power was very weak, and couldn't enlarge export effectively.

中国近代工业品在海外市场上的局促，主要在于质量低下、款式不对路、缺乏标准化和市场开拓不足，竞争力十分微弱，无法有效地扩大出口，比进口替代高一层次的出口替代始终不能发展起来。

Key to these direct detections have been big telescopes and the latest technology to pick out a vanishingly faint planet from its host star's overwhelming glare.

这些直接观测的关键在于大望远镜和最新技术，用它们来从主恒星强烈的光芒中捕捉到行星微弱的几乎消失的踪影。

这些直接检测的关键在于运用大望远镜和最新技术去挑选宿主恒星无法抵挡的眩光下难以察觉的微弱的行星。

Because the biggest characteristic of ECG and pulse signals is very weak, vulnerably to external signal interference, such interference, mainly caused by mobile electrode baseline drift (generally less than 1Hz), power-frequency interference (50Hz), EMG Interference.

由于心电信号和脉搏信号最大特点就是信号十分微弱，容易受到外部信号的干扰，这些干扰主要来(来源：7bABC论文网www.abclunwen.com)自电极移动引起基线漂移(一般小于1Hz)，电源工频干扰(50Hz)，肌电干扰。

When I see the unhappiness of friends and imperfect of this world, the only thing I can do is sighing or weepy, because I am too weak to change anything.

看到朋友的忧伤，觉察到社会的阴暗，我唯一能做的就是叹息和哭泣。因为我太微弱，我无力改变任何事情。

Openness to experience and internet information service preference have no significant effect on PIU.

在神经质高分组中，互联网社交、娱乐和信息服务偏好与PIU的正向关系都是最强的；在神经质低分组中，互联网社交服务偏好与PIU的正向关系最弱，而互联网娱乐和信息服务偏好与PIU甚至呈现出微弱的反向关系。

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。
