The proved gold reserve within the belt has up to about 150 tonnage since 1820 when it was discovered.

有别于前人的研究成果，本文提出夹皮沟金矿带恰好位于高级区与夹皮沟花岗－绿岩带的接触部位，形成以夹皮沟金矿化带为中心的矿化分带。

This model,close to experiment,approximates normal model due to the ionization increasing at h...

同时为了充分利用埋沟器件体内沟道的优势，对埋沟掺杂的浓度和深度也进行了合理的设计。

The soil erosion process on the slope was clearly divided into sheet erosion stage, rill erosion developing stage and rill erosion stable stage. Before lOminutes of rainfalls, the percentage of sheet erosion amount to total erosion amount was more than 90%, and it indicated that sheet erosion happened on the slope. This percentage sharply decreased before SOminutes of rainfall time, on the other hand, the percentage of rill erosion amount to total erosion amount increased in curve form with rainfall time.

在降雨前10min左右，面蚀贡献率约占坡面侵蚀总量的90%以上，为面蚀阶段；随着降雨时间的延续，面蚀贡献率先急剧递减最后在第30min左右基本达到稳定，细沟侵蚀贡献率则出现相反趋势，此为细沟发育阶段；降雨后期，面蚀和细沟侵蚀贡献率的变化趋势逐渐变缓且基本达到稳定。

In the soft tissue measurements, the value of soft tissue facial angle and B'-Pos-FH in the first extraction group was less than those in the second extraction group significantly. After treatment all the patients had an increase in S-Ns-Pos angle, soft tissue facial angle, B'-Pos-FH and depth of mentolabial groove. At the same time, soft tissue convexity angle was diminished obviously. But the change was not significant between the two premolar extraction groups.

2在对软组织项目的测量中，治疗前第一前磨牙拔除组的软组织面角、颏沟倾角均小于第二前磨牙拔除组，治疗后2组均出现软组织面凸角减少，颏凸角、软组织面角、颏沟倾角、颏唇沟深度增加；但2组在各项测量项目的变化上无显著组间差别。

Maturity of Lower Cretaceous source rock, researched by the authors, is closely relative to the deposition thickness of the Tertiary and the Quaternary. It shows that source rock at the depth of 4,000-4,400m is low mature, and 4,400-5,200m is in the peak of oil generating. Correspondingly, the source rock of the Zhonggou Formation is immature; the Upper Xiagou Formation is low mature; and the Lower Xiagou Formation and the Upper Chijinpu Formation are in the peak of oil-generating; and the Lower Chijinpu Formation is at the stage of generation of condensate-wet gas with high maturity. There is no source rock reaching the overmature stage of dry gas at present.

可溶有机质转化率、镜质体反射率、热解、生物标志物特征等参数表明：青南凹陷中部的下白垩统烃源岩生油门限深度为4000m（相应的镜质体反射率为0.65％），埋深4000～4400m为低成熟阶段，埋深4400～5200m为成熟生油高峰阶段，因此中沟组烃源岩未成熟，下沟组上部烃源岩低成熟，下沟组下部和赤金堡组上部烃源岩处于成熟生油高峰阶段，赤金堡组下部烃源岩处于高成熟的凝析油—湿气阶段，目前尚无烃源岩达过成熟干气阶段。

Film-furrow irrigation is a combination of techniques of film-mulching irrigation and furrow irrigation.

膜沟灌溉是与地膜覆盖技术相结合的沟灌，它将带有渗水孔的地膜敷贴在灌水沟内形成膜沟，灌溉时水在沟内的膜上流动，并通过膜孔渗入土壤。

From 1998 to 2000, soil moistures were measured every April to October by using TDR systems installed in different gully positions.

目前的土壤侵蚀预报模型没有包括切沟侵蚀，因此研究切沟中土壤水分空间变化是建立切沟侵蚀模型的基础，也是恢复植被的基础。

But little gully erosion model included in soil erosion models. It is necessary to study soil moistures in a gully watershed for establishing a gully erosion model and restoring vegetation.

目前的土壤侵蚀预报模型没有包括切沟侵蚀，因此研究切沟中土壤水分空间变化是建立切沟侵蚀模型的基础，也是恢复植被的基础。

The machine of Rice Rope Seeding, on the one hand, create a favorable conditions for opener working through anti-blocking boards to push rice stubble and other debris out sowing belt. On the other hand, it can finish these working, which are anti- blocking work、opening work、sowing work、banking work and compacting work in field.

种绳直播机一方面依靠防堵板将稻(来源：ABC8d论文86网www.abclunwen.com)茬等杂物推送出播种带，为开沟器开沟作业创造良好的条件，另一方面通过播放机构顺利的将种绳播放到田地里，实现防堵、开沟、播种、覆土和整压一次完成。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
