查询词典 unpinning

You stand there, a mere body or lay figure, and they still go on delicately ripping out sleeves and collars with their little penknives, pinning and unpinning, and making mysterious signs with chalk, and you have long ceased to understand what all the bother is about.

你站着不过是一具肉身或一个人体模型，裁缝们却小心翼翼地用小折刀扯出做袖子和领子的布，别针别上又取下，还用粉笔划些神秘的记号，而你老早就纳闷如此煞费周章意义何在。

The young girl obediently yielded to her old companion's wish and unpinning the cumbersome, sombre drapery from her bonnet, folded it neatly and laid it upon the seat in front of her.

小姑娘顺从地按照她老同伴的愿望做了，从她的软帽上拿下了那笨重的，阴暗的呢绒面纱，整齐地叠起来，放在了她前面的位子上。

Do not remove pins if the wing is leaning against the pins or putting pressure on the pins. Use the hydraulics to pull the wings in completely before unpinning them.

如果折叠架是倾斜的靠到锁定销上或者压到锁定销上，应当用液压完全拉动折叠架后再拔去它们。

A new model is presented for the physically-consistent description of plastic instabilities referred to PLC effect. The model takes account of two competing processes during the DSA on micro-scale: the additional pinning of diffusing solute atom on mobile dislocations and the unpinning of the mobile dislocation with the aid of thermal activation.

建立了一个基于动态应变时效过程中热激活机制和二阶应变梯度空间耦合方式的宏观唯象模型，该模型刻画了材料内部在微细观尺度上彼此协同和相互竞争的两个过程：溶质原子对可动位错的时效钉扎和可动位错在热激活辅助下的挣脱。

The critical shear stress unpinning the 60 dislocation from the ring-shaped hexagonal vacancy defect decreases as the temperature increases in the models, and approaches a stable value of 0.6GPa as the temperature is higher than 300K, bellow the misfit stress in common SiGe heterostructures, which indicates that the 60 dislocation can not be pinned by the ring-shaped hexagonal vacancy defects in this case.

模拟结果表明：使位错不被钉扎住的临界外加剪应力随着温度的上升而减小，在上述模型中当温度达到300K以上就稳定于0.6GPa附近，小于SiGe体系中的失配应力，说明空位缺陷不会成为60位错的钉扎点，仅会对其运动产生迟滞。

At 1273K, the density of dislocations were considerably decreased in deformed TiAlMnNb alloy, twinning and 11 superdislocations were hardly observed, but few 1/212 superdislocations and 01 perfect dislocations were found in deformed TiAlMnNb alloy. In high temperature range, brittle-to ductile transition had already occurred in deformed TiAlMnNb alloy, unpinning and climbing were the dominant deformation behavior in TiAlMnNb alloy. In the same way as TiAlMnNb alloy, different distinguishing feature the dislocation configuration at low, intermediate and high temperatures emerged in deformed TiAlMnNbB alloy.

在中温区域，合金中位错组态变化可分为两个小区域，在673K以下，合金的位错组态有孪晶、1/210单位位错和少量的11超点阵位错；这一温度区间内孪晶和位错密度都大大提高，不同系统的孪晶相互交割阻碍了孪生的继续发展，不同方向的位错相互交割阻碍位错进一步滑移，同时孪晶界面也阻碍了位错的运动。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
