桩材

And yet what John Hope Franklin collected, over a lifetime of scholarship, were scraps of horror. Five dollars for the cost of a branding iron. A deed of sale, in Virginia in 1829, for a male slave "of a yellow colour" who "is not in the habit of running away".

不过，终其学术生涯一生，富氏所收集的却是零散的惊怖之材：一块价值五美元的烙铁；一桩发生在1829年的弗吉尼亚的奴隶买卖，该名待售的"黄皮肤"男奴"并不惯于潜逃"；抑或是幼小的爱德华·约翰逊于1860年提供的一段证词。

Results of eight investigations make use of the soil experience and analysis form the disaster area of 921 earthquakes, The result of soil investigation and analysis form the disaster area of 921 earthquakes, Understanding such as: 1. The recommand degree depth of drive stake is 40% of stake length for stake and wattling method on dry soil condition. And 58% of stake lengths on unsaturated condition. And 67% of stake length on soil saturated condition.

本研究乃以8个涵盖921集集地震灾区之区域地质样区，采取土样进行试验分析与计算，经研究调查结果得知，乾土时打桩编栅工法桩材的贯入深度建议为桩材长度之40%，半饱和时的桩的贯入深度建议为桩材长度之58%，完全饱和时桩贯入深度建议为桩材长度之67%。

Shanyou 63 and Minghui 63 were used as materials and three stubble height treatments(10 cm,20 cm to 40 cm) were set to study the effect of different stubble height on growth and yield of ratooning rice.

以汕优63、明恢63为试材，设10、20、40 cm3个留桩高度处理，研究了不同留桩高度对再生稻生长发育及产量的影响。

The results indicate that when soil and pile are same, the shear stresses between pile and soil under the ultimate situations of different modes are different; the negative friction on pile induced by surcharge is maximum; and the negative friction of uplift pile is minimum; the friction of pile top induced by pressing pile and bottom-loaded pile is between them.

结果表明，同种土体和桩体条件下，各种模式达到极限状态时桩－土间剪切应力不同，堆载作用下负摩擦力值最大，抗拔桩负摩阻力值最小，桩顶受压桩、托桩的摩阻力值介于其间；桩材泊松比在0.15~0.35范围内时，桩侧摩阻力随泊松比的增大而增大。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
