道路施工

Finally, we selected Gemini surfactant GNP, GTB and trimeric surfactant TNP to be used as emulsifier to achieve cationic slow breaking and quick-setting bituminous emulsion.

与结构类同的传统型乳化剂相比，Gemini表面活性剂GNP和GTB以及三聚体阳离子表面活性剂TNP具有更高表面活性和较强的荷电强度，因而更适用于慢裂快凝乳化沥青稀浆封层道路施工技术，其表面活性剂的结构对稀浆封层沥青乳液与矿料的拌和时间有重要影响，其拌和时间由长到短依次为：TNP＞GTB＞GNP。

Roadwork is all done with spades , heavy woodcutting with hand-axes

道路施工都是用铁锹完成的，沉重的伐木工作是用斧头--所有工作都要符合规定的进度，否则立刻就减少食物。

This drill rig is suitable to drill blasthole,anchor-cable hole and grouting hole with φ85-φ125mm diameters,0-50m depths and any dip angle of 00-3600 in various rock formations in underground mines,open pit mines,water conservancy projects and other engineering such as hydroelectric,building,harbour,airport,road construction and consolidation of slope etc..especially suitable for the operation in narrow underground space.

其导轨架较为短小，占地空间小，适用于矿山井下和露天、建筑、水利水电、港湾、机场、道路施工及边坡加固等工程，尤其适合井下狭窄场地作业。可在各类岩层中钻凿φ85-φ125mm、深度0-50米，钻孔倾角00-3600任意角度的炮孔、锚索孔和灌浆孔。

Roadworks are causing bottlenecks in the city centre.

道路施工导致市中心交通阻塞。

Roadworks : What are the benefits of modelling temporary traffic management arrangements ? by Stephen Cragg of SIAS.

Stephen Cragg，道路施工：模拟临时交通管理措施的利益？

Leaving aside roadworks, traffic jams are ultimately caused by drivers doing something stupid—taking unnecessary risks, misjudging distances, over-estimating their own skill or simply driving too fast.

不考虑道路施工因素，堵车归根到底是由司机的愚昧行为造成的：冒无谓的风险、错误估计距离、高估个人车技或是超速。

We shouldn't have so much roadwork or building sites.

我们不应该有这麼多的道路施工和建筑工地。

And combined with real projects,it illustrates the features and steps of measuring and setting-out in polar coordinate setting-out method and connecting traverse setting-out method,which enhances people s knowledge about the two methods and meanwhile makes measuring and setting out faster and better.

对城市道路施工的放线方法进行简要的分析，并结合实际工程对极坐标放线法和附合导线放线法的特点及测放步骤进行了说明，以提高人们对这两种方法的认识，从而使测量的放线工作更快、更顺利。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
