Fantastic ridges and swept back shapes strongly suggest that energetic radiation and shock waves from NGC 602's massive young stars have eroded the dusty material and triggered a progression of star formation moving away from the cluster's center.

梦幻的脊状尘埃和云气说明了在NGC 602 里面，从大质量年轻恒星发出的高能的辐射和震波已经影响到附近的尘埃，并从星云中心往外触发了一连串的恒星形成。

Inside the perispore,there are large cavities which are formed mainly by the upheaval of the outer perispore.The lophate folds and superficial ornamentation of spores are formed by the upheaval of the outer perispore.

周壁内有大的空腔，主要是由周壁外层向外隆起形成的，隆起进而形成了孢子的脊状褶皱和表面纹饰。

Investigation into the drag-reduction mechanism of riblet surfaces makes placoid scale a perfect object to biomaterial research.

鲨鱼体表覆有一层细小的盾鳞，盾鳞上的脊状突起称为肋条，肋条之间构成具圆弧底的沟槽。

Experimental results show that the vehicle models with transverse riblets surface have obvious drag reduction effect under certain velocity range, the maximal drag reduction effect is 23.5%.

实验结果表明，具有横向脊状表面的航行器模型在一定来流速度范围内具有很好的减阻效果，实验获得的最大减阻量为23.5%。

According to the geochemical data, the formation of mantle peridotite might be: during the spreading of ocean floor, the MOR mantle underwent variable degrees of partial melting and formed the depleted mantle peridotite with podiform chromitite; during the spreading of ocean basin, intra-ocean subduction happened, REE and LILE rich fluids containing water derived from the subduction slab migrated upwards and metasomatism happened to peridotite relic.

康金拉矿区的地幔橄榄岩的地球化学特征反映了其形成过程的复杂性，表现为：洋底扩张期间，扩张脊下的MOR型地幔的经历了不同程度的部分熔融，形成了亏损地幔橄榄岩，该地幔橄榄岩中赋存了来自深部的豆荚状铬铁矿。

By using the foam mats for its head fixation and standard head coils for emission and reception,the scanner begin its routine scannings in the position of the axis,sagittal,coronal SE T1WI(TR/TE=476/15ms) and axis TSE T2WI (TR/TE=3647/100ms).The matrix of the scanner is 256×256,the slick thickness of it 5mm and the spacing of it 0mm.1H-MRS is located on the side of the hippocampus by using the T2WI axis.

采用泡沫垫进行头部固定，使用标准头线圈作为发射和接收线圈，常规进行轴位、矢状位和冠状位SE T_1WI(TR/TE=476/15ms)和轴位TSET_2WI(TR/TE=3647/100ms)扫描，矩阵256×256，层厚5mm、间距0mm，1H-MRS采用T_2WI轴位定位于一侧海马选取正方体感兴趣区，体素大小为10mm×10mm×10mm，并在轴位、矢状位和冠状位上观察，使所选择的VOI尽量避开侧脑室及脑沟池内的脑脊液。

Time (3Xrpm) turning table speed. In addition, while the teeth of the tri-cone bit interact with the formation, the drillstring will generate tiny axial vibration. As the vibration is symphonious to the tri-spine well bottom, the vibration signal exhibits amplitude modulation character. This character had been verified by in-site measurement data and numerical simulation.

另外，三牙轮钻头与地层作用破岩时牙轮牙齿产生啮合振动，由于三脊状井底对啮合振动进行幅度调制形成调幅信号，根据调幅信号的频率特征，振动信号在频域表现为具有一定边带的一束谱线，它是钻头工作正常的&健康信号&。

Ridged, like the keel of a boat.
