凹坑

When existing liquid, the groove sample has biggest friction and the pit sample has biggest adhesive force.

有液体时，水平摩擦力是凹槽型的最大，垂直吸附力是凹坑型的最大。

With morphology characteristics of erosion concave of Ag and Pd contact materials in nitrogen and air being compared, influence on erosion, welding and breakdown voltage of contact for nitrogen and SF_6 being analyzed, influence on contact for the formic acid, toluene, carbinol and distilled water being analyzed, it was showed that the influence on performance parameters of relay contact for various atmospheres is very com...

通过比较触头材料Ag和Pd分别在氮气和空气中侵蚀凹坑的形状特征，分析了氮气和SF6等气氛对触头侵蚀、熔焊、耐压的影响，及甲酸、甲苯、甲醇、蒸馏水等对触头的影响，表明各种气氛对继电器触头性能参数的影响十分复杂，该影响涉及对电弧运动规律的影响和与材料的化学反应。

In its original state, a CD-WO player recognizes a track consisting of lands. The absorption layer in the pre-grooved trackis heated to above 250 with a laser three to four times the intensity of a reading player.

在初始状态下，CD-WO播放器读出的轨道上均为非凹坑，处于预先挖槽的轨道中的吸收层被超过250°C的高温加热，这个激光强度是一般读盘播放时强度的3∽4倍。

Chattanooga is one of four cities to receive donations for the repairs but there is a catch.

但有一点是，这些重新填好的凹坑要刷上"由肯德基修整"。

The results showed that a concavity in the surface could be clearly observed at the center of starches.

结果表明：微波淀粉颗粒表面出现凹坑，降低了膨胀度和溶解度、冻溶稳定性。

Notch and groove were produced on fiber's surface by plasma's pHysical bump and corrasion, meanwhile oxygenic or nitrogenic radicals were also grafted on the surface. Through hydrolyzation, acetate fiber's surface will be denuded by cellulase enzyme. Surface of the fiber will be granulated and specific surface area will be enlarged by plasma and enzyme treatment, therefore obviously improve fiber's surface performance.

等离子体对纤维的物理撞击和表面刻蚀使纤维表面产生凹坑和沟槽，同时可在纤维材料表面引入含氧或含氮基团；而纤维素酶对纤维素的水解作用，促使纤维表面被剥蚀；等离子体与生物酶处理都能使纤维表面粗糙化，比表面积增加，使纤维的表面性能得到明显改善。

Can you tell me what caused the crater?

你能否告诉我是什么造成了这个凹坑？

Can you hammer out the dent in the side of my car?

你能把我汽车侧面的凹坑敲平吗？

We could put the stone surface under the sunlight lamp or sun, granite and marble , stone products observe its reflecting surface, then could see clearly these kind of concave and strip, if it is because of the mineral, we could ignore it, but if it is because of the bad polish, then had better to avoid to purchase this kind of stone.

我们把加工好的石材表面对着太阳光或日光灯，观察反光面就可以清楚发现如图所示的各种凹坑和条痕，对于那些无规则的细小凹坑可能是由石材组成矿物的一些自身缺陷造成的，可以不去考虑，而如果在石材的表面发现一些有规律的条痕，则是由于加工质量较差造成的，选购时应尽量避免这样的石材。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
