Using the latest paleontological, magnetostratigraphic and chronological data and the lasting time of the high-resolution sequences, the authors have made a detailed chronostratigraphic division of the Jixi Group and determined the Jixi Group formed in the Early Cretaceous early Valaginian to middle Albian. In the group, the Didao Formation formed at 130.9±128.3 Ma, the Chengzihe Formation at 125.1±116 Ma, the Muling Formation at 116±106.9 Ma, and the Dongshan Formation at 106.9±101.7 Ma.

提要：利用最新的古生物、磁性地层年代资料及高分辨率层序延续时间推算，对鸡西群进行了精细的年代地层划分，确定了鸡西群形成时间为早白垩世凡兰吟早期—阿尔布中期，其中滴道组形成时间为130.9～128.3 Ma，城子河组形成时间为125.1～116 Ma，穆棱组形成时间为116～106.9 Ma，东山组形成时间为106.9～101.7 Ma。

So ,the wolf went to the grocer for a block of calcareousness and eat it down,so ,his voice is turn to soft.then ,he came back to knock at the door of the goat,shouted loudly: open the door ,my baby goats,it's ur mom coming back~!

于是，狼跑到杂货商那里，买了一大块白垩土，吃了下去，结果嗓子变细了。然后它又回来敲山羊家的门，喊道：开门哪，我的好孩子。

The results indicated that the epistatic effects played an important role on the inheritance about grain shape and chalkiness degree in rice.

结果表明，上位性QTL和主效QTL一样在稻米粒形和垩白度的遗传中起着重要的作用。

SHRIMP and LA-ICP-MS zircon U-Pb dating yielded some age data: the Longchahe porphyritic granite is (81.2±1.4)~(83.2±1.4) Ma, the porphyritic granite in Malage-Songshujia area is (82.8±1.7) Ma, the porphyritic granite in Laochang area is (83.3±1.6) Ma and the Baishachong equigranular granite is (77.4±2.5) Ma.

文章首次采用LA-ICP-MS和SHRIMP U-Pb方法对研究区内的花岗岩进行了精确定年，数据表明，不同类型的花岗岩同时或近于同时形成。龙岔河似斑状花岗岩主要形成于(82.0±0.3)~(83.2±1.4)Ma，马拉格－松树脚似斑状花岗岩形成于(82.8±1.7)Ma，老厂似斑状花岗岩形成于(83.3±1.6)Ma，白沙冲等粒花岗岩形成于(77.4±2.5)Ma，均集中形成于晚白垩世。

Large amount of research results show that K1qn1 is favorable for the development of lithologic reservoirs in the study area.

大量的研究结果表明，该区下白垩统青山口组一段是岩性油气藏的有利发育层段。

Among the magnoliaceous fossils, the earliest one is Archimagnolia rostrato-stylosa Tao et Zhang reported from the Lower Cretaceous Dalazi Formation of Yanji district, Northeast China.

该科最早的化石记录为中国东北延吉地区早白垩世大拉子组的喙柱始木兰Archimagnolia rostrato-stylosa Tao et Zhang。

The Cretaceous sedimentary rocks were baked by the basaltic lava flow erupted in the Early Miocene, contracting in volume owing to loss of water contained mainly in the clays of the clastic rocks, and thus forming the columnar jointing. According to the occurrences of jointing and the sedimentary strata the authors calculated the two different rotations of the Mellit block: the block tilted toward 338° for 18° from Late Cretaceous to the beginning of Miocene, and tilted toward 138° for 18° since Miocene.

可以合理地假定柱状节理在形成时是垂直于大地基准面的，根据柱状节理和沉积岩层的产状，笔者计算出Mellit地块的两期旋转事件：自晚白垩世初期到中新世初期该地块向338°方向倾斜了18°，而自中新世以来又向138°方向倾斜了18°。

Early for the rapid accumulation of a class molasse stone construction, medium-shallow lake is the foreshore - semi-deep lake sediments (mainly covered reservoir sedimentation period), advanced to the river swamps of the deposition, thus to the Early Cretaceous as the main lake sediment Stage came to an end.

早期为快速堆积的一套类磨拉石建造，中期是滨浅湖-半深湖沉积、晚期为河流沼泽相沉积，至此以早白垩世为主体的湖盆沉积阶段宣告结束。

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。
