This paper developed an extensible, scalable and portable software framework for train maintenance using industrial robots.

The best site condition is the shade of low pitch which is well drained and rich in soil layer, its growth improved 19.1 percent than control.

最适宜生长立地条件是排水良好、土层肥沃的阴坡山下部缓坡地带，其生长量比对照提高19.1%。

These are: body language, avoiding eye contact, when their voice changes from high to low pitch, and when they contradict themselves.

它们是：肢体语言，避免眼神交流，但他们的声音由高变低，以及他们自相矛盾。

The incidence of tinnitus is 27.9%, mostly with a low pitch and transient feature.

耳鸣晚期发病率为27.9%，以间歇低调为主。

Cases had differential pitch tinnitus, mainly low pitch with poor speech discrimination.

结果：7例伴不同音调耳鸣，以低调为主。言语分辨力差。

In both cases, the authors found that women had a strong preference for the low pitch male voice and remembered objects more accurately when they have been introduced by the deep male voice.

在两个试验中，研究人员都发现，男性的低沉嗓音更受女性青睐。倘若一件物品是由一个男低音介绍的，那么女性对这件物品的记忆就更准确。

In the first experiment, 45 women were initially shown an image of a single object while listening to the name of the object spoken either by a high or low pitch male or female manipulated voice.

在第一项试验中，让45名女性看一个单个物品的图片，边听着高或低的音调男或女操作过的声音读出来的物体的名称。

And dip slip one with low pitch or one on which there are locking regions along a fault, surface ruptures rarely occur, in stead of seriously secondary surface damages on a wide area.
