1·China formally entered the ageing society in 1999, now it has been in the aging acceleration period.

中国在1999年正式进入老龄社会，并已经进入加速老龄化时期。

2·When the acceleration period has terminated, the switch means is controlled by a PWM pulse of the duty ratio in accordance with the speed instruction data, there by driving the DC motor.

在该加速期间结束时，以占空比与速度指令数据对应的PW M脉冲来控制开关机构，从而驱动该直流马达。

3·Our country is being in urbanized the acceleration period, the environment question which the city faces is day by day prominent, the city natural ecology already received the enormous destruction.

我国正处于城市化的加速期，城市所面临的环境问题日益突出，城市自然生态已经受到极大的破坏。

4·If I have a high acceleration, the period will be short, and that's exactly what you see.

如果有大的加速度，周期就短，那就是，你们所看到的。

5·If the acceleration goes down, the period of oscillation goes up.

如果加速度减小，振荡周期变大。

6·So now the restoring force doubles and the mass doubles, the acceleration remains the same, the period remains the same.

所以现在回复力加倍，物体质量加倍，加速度不变，周期不变。

7·So let's be clear. The jury is back. The verdict is in. There is no electronic-based cause for unintended high-speed acceleration in Toyotas. Period.

我们必须明确，陪审团已经回来了，判决已经出炉。丰田汽车加速器突然加速并不是电子元件的原因。

8·Early Production Containment Period - Production runs during the start-up and acceleration of a new or changed product or manufacturing process.

早期生产控制阶段-在新产品或发生改变的产品或生产过程的起步和加速阶段中的生产运行。

9·However, case detection rates, after a period of acceleration, leveled off in 2007 at around 60% globally, short of WHO's goal of 70%.

然而，全球病例检出率在经历一个加速期后，于2007年平稳保持在60%左右，低于WHO设定目标70%。

10·The decisive factor is that the differentiation is not based on a sample over a discrete time period, but is a physical effect, so that the user sees a dynamic, low-noise acceleration signal.

决定性的因素是这种区分是没有根据的样本离散多时间，但它是一个物理作用，使用户会看到一个充满活力，低噪声加速度信号。
