大坡度

At the same time,it designed the project of construction supervision and measure aimed at the strengthening bridge by external presttessing,through the contrast between the result in theory and fact,we can see that it is feasible to use predigestion's computing based on elasticity to analyse continuous rigid frame briges reinforced by external presttessing ,and it can ignore the effect of the second stress. So, it can be capable of the analyses in the strengthening bridge by external presttessing using the method of controlling by flexibility and stress to set up the model of scathe,and,the method of external presttessing can ensure stress reserve of the main beam, to reduce effectively PrinciPal tensile stress, to renew line state of bridge structure and gradient. The effect of strengthenment was obvious and the reinforcement scheme was successful.

同时，进行了该桥体外预应力加固监测方案设计，并通过理论计算结果与实际监测成果的比较，验证了在施工阶段及正常使用阶段，大跨连续刚构体系的体外预应力加固计算中忽略二次应力增量的影响，采用弹性分析方法进行简化计算的可行性，进而说明采用双控拟合方法建立的结构损伤模型能够满足体外预应力加固计算的要求，并且体外预应力加固法能够显著增大主梁的应力储备、有效地减少了主拉应力、恢复了桥面线形和坡度，加固效果明显，加固方式成功。

The mechanical strength of paddy soil in rice stubble field changed greatly with changing soil moisture content.

稻茬田土壤抗机械强度随含水量变化的曲线的坡度很大，麦茬田则较小。

Optimal habitats of the arboreal Hoolock gibbon were characterized by having connected crowns of tall trees (14.14±3.19m) with large basal area (ACTBH: 90.72±26.12cm), steep slopes and high bamboo density, providing reduced ground disturbance and plentiful food for Hoolock gibbons in spring.

作为树栖灵长类，具有-定基面积的连续乔木［高度(14.14±3.19)m，胸围(90.72±26.12)cm］树冠层是白眉长臂猿的适宜生境；较大的坡度(39.98±8.10°)减少了来自地面的干扰；而竹林是白眉长臂猿春季重要的取食地。

The results showed that the flow reattachment distance in the lee side of various dune models are ranged from 4.8H to 10.8H depending on different stoss slopes, the maximum of flow reattachment distance was found in the lee side of the transverse dune with a 15° stoss slope angle.

实验结果表明，当来流风速垂直于沙丘脊线时，沙丘背风侧的气流重附距离介于4.8H～10.8H之间，最大重附距离出现在迎风坡坡度为15 的沙丘背风侧；沙丘迎风坡坡度是控制背风侧气流重附距离的主要因素，而自由风速对气流重附距离的控制作用较小。

The middle and lower parts of woodland and grassland had higher soil water contents during rainy season, which resulted from smaller evapotranspiration and more infiltrated water with a lower gradient. However, upslope runoff infiltration was another reason for hillslope with a lower cover ratio, such as bare land.

雨季林草地坡中下部土壤水分含量较高的原因，可能主要与其蒸散较小且坡度较缓导致入渗水量较多有关；但是对于植被覆盖度较低的坡地，坡中下部土壤水分含量较高还与上方来水有较大的关系。

In the regular wave tests at the same of slope bottom, the cut off frequency and the frequency of the maximum energy of infra-gravity wave are not changed for different initial wave steepness.

文中以相同相对水深之规则波试验去做比较，在频率方面，波浪尖锐度改变，其截断频率及亚重力波频率无太大的改变，而坡度改变，亚重力波频率会出现移至低频的现象。

The velocity of the rock block rolling from a zigzag slope with a steeper segment near the slope toe is larger than that form a concaved slope.

当边坡总体坡度相同时，上缓下陡的折线边坡，滚石落地速度最大；而内凹的曲线边坡，滚石落地速度最小。

Ballastless track features little maintenance,high reliability,long service life,low cost compared to its service life, low structure height, large transverse track resistance, ballast splashing—proof,and flexible superelevation and gradient.
