Baijiahai area is an old apophysis , which lie in the line intersection of three source sags . In the courses of oil-gas remotion , it is always in the favorable remotion channels and controls the effect of plane remotion of the oil-gas .

白家海凸起是夹持于三大生油凹陷的一个形成较早继承性古隆起，在整个油气运移的过程中始终处于有利的运移通道上，它控制着油气的平面运移效应。

The reservoir-forming model of Huizhou Sag is almost two-step according to reservoir-forming stage, and there are single-source and two-source reservoir according to oil sources. There are three reservoir-forming models of abrupt slope type, apophysis type and gentle slope type according to structural form.

惠州凹陷的油气藏成藏模式，从成藏期次上分多为两期成藏，从油源上分有单油源和双油源两种成藏模式，构造形式上有陡坡型、隆起型和缓坡型成藏模式。

Thus voicing can be more effective in changing the apparent key weight than lead weights.

这个移动的距离，不能够是一个琴弦的间距，因为如此会使得音槌触击琴弦时，仍是在音槌凹陷的位置（译注：在 3 条琴弦的位置，相对应的音槌上也有 3 个凹槽，这是音槌正常触击琴弦的位置）。

Of fair length, distance from stop to occiput being approximately equal to distance between ears.

最理想的长度是从凹陷部位的长度与双耳间的距离大致相等。

Long geological evaluation and Cenozoic structural and fault activities led to the formation of multiple types of oil and gas pools from Neogene to Archeozoic Era and resulted in a great deal of oil and gas accumulations in uplifts and sags.

漫长的地质演化和新生代构造断裂活动形成了上第三系至太古界多层系多类型的油气藏，在凹陷、凸起的各部位，分布着大型油气聚集带。

Lithology of Tertiary oil bearing reservoir in Taibei Sag is mainly fine sandstone and petrological types are mainly lithic arkose and hybrid sandstone.

台北凹陷第三系含油储层岩性以细砂岩为主，岩石学类型以岩屑长石砂岩和混合砂岩为主，含气储层岩性以砂砾岩为主，岩石学类型为岩屑砂砾岩。

Meso-experiment of fine sandstone thermal crack laws;2. Lithology of Tertiary oil bearing reservoir in Taibei Sag is mainly fine sandstone and petrological types are mainly lithic arkose and hybrid sandstone.

台北凹陷第三系含油储层岩性以细砂岩为主，岩石学类型以岩屑长石砂岩和混合砂岩为主，含气储层岩性以砂砾岩为主，岩石学类型为岩屑砂砾岩。

In whole test process, to compared with control group, hepatic hepcidin gene expression of test group on different phases had obviously differences with retinoic acid was administered. On early phase of test group , relative gene expression contents of hepcidin were gradually fall and the lowest level was on 8th、9th、10th day, then the hepcidin level gradually was ascendent. The curve was like a cavate parabola.

在实验周期内，模型组与对照组比较，肝脏铁调素基因表达在维甲酸灌胃的不同时间，存在明显差异：早期5、6、7天铁调素基因相对表达量逐渐下降，在第8、9、10天达到较低值，随后有回升，呈现凹陷的抛物线变化趋势；而对照组基本处于水平的轻微波动变化。

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。
