Fertilizer Entec26 contained DMPP (new type of nitrification inhibiter) could also decrease soil nitrate leaching.

证明在高灌水量条件下，尿素+玉米秸杆处理，使土壤矿质氮固定和微生物氮增加，降低了土壤硝态氮的下层累积和向下淋洗；施用含新型硝化抑制剂DMPP的肥料Entec26也能降低土壤硝态氮的向下淋洗。

After thermal annealing at 2000C for 3 hours there's no atomic interdiffusion between copper and underlying contact metals and the devices showed little change in device performance.

经过摄氏两百度的高温退火三个小时以后，铜金属以及下层的接触金属间并没有金属原子交互扩散的现象；元件特性在经过热退火以后并未产生明显的变化。

The lower layer, Internet Protocol, handles the address part of each packet so that it gets to the right destination.

下层，互联网协议，处理每个数据包的地址部分，以便它到达正确的目的地。

Sable and white – which is a coat with black guard hairs and varying amounts of light cream to dark "Irish setter" red undercoat.

黑貂和白--带有黑色真毛的被毛，并且有从大量的亮奶油色过度到黑色爱尔兰赛特犬一样的红色下层绒毛

This means that the crust floats in a state of equilibrium, called isostasy.

当高层的物质被地质作用侵蚀，下层的地壳便升起来以作补偿。

Think of the civil rights heroes and foot-soldiers who marched, protested and risked their lives to bring about the end to segregation and Jim Crow.

感谢人权英雄和下层民众，他们行进、抗议，冒着生命危险终结了种族隔离和对黑人的歧视。

A finger-length katydid disguised as lichen-coated bark barely registers in the dim understory of a Panama forest.

Tropical forest is wetter and usually supports only knee-high fires that spread slowly through the understorey.

热带森林更加潮湿并且通常只能维持在下层植被中蔓延的膝盖高的火情。

OD estimation was divided into fixed steps, with every step containing a bi-level programming. The upper-level problem was a generalized least squares estimator, while the lower level problem was a stochastic user equilibrium model. Namely, based on generalized least squares estimator and stochastic user equilibrium, a new estimator of the OD matrix was proposed by target matrix and traffic counts updating.

将OD估计分为固定的步数，每一步都是一个双层规划，上层为广义最小二乘估计，下层为随机用户均衡分配模型，即以广义最小二乘估计和随机用户均衡分配模型为基础，通过更新估计模型中目标矩阵和实测路段上的流量来估计OD矩阵。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
