With the same cutting parameters, same chip types can be gained in either the nodal zone or the internodal zone. In other words, the principles of chip formation are entirely the same in these two different zones.

在试验条件相同的情况下，对竹节部和节间材切削，会形成相同类型的切屑，即其切屑形成机理相同。

The second order parameters 〈P_2〉_λ and the values of introrse intensity Q in different shells of the droplets on 2DR boundary conditions at different reduced temperatures were calculated.

取沿向列相液晶微滴表面切向随机取向边界条件，计算了不同温度下二阶序参量〈P2〉λ和沿表面切向的内禀强度Q在液滴内不同区域的数值，发现在低温时，Q值从液滴外层到内层有逐渐减小的趋势，外层接近于1。

In Angle's Class II,division 1 patients, the upper incisors labially inclined and closed up the upper lip,the lower lip reduced the covering with the upper incisors' crown.

安氏II类1分类错唇齿关系形态特征表现为：上中切牙明显唇倾并与上唇过度贴合，上唇外翻，下唇对上中切牙覆盖明显减少。

Assisted by DNA2.0 and Gene2Oliga software, we optimized the codon usage and secondary structure of RNA and induced enzyme sites Cla I (237 site) and Pst I (475 site) into the gene. In the first step, fragments F1 (237 bp), F2 (238 bp) and F3 (422 bp) were separately synthesized by assembly PCR. In the second step, fragments F1, F2 and F3 were separately digested by Cla I and Pst I, and then ligated into a full length lipA gene.

首先在DNA2.0和Gene2Oliga软件辅助下对lipA基因密码子及RNA二级结构进行优化并引入Cla I(237位)和Pst I(475位)酶切位点；通过组装PCR分别合成lipA基因的各片段F1(237 bp)、F2(238 bp)和F3(422 bp)；通过该基因内的Cla I和Pst I限制性酶切位点连接成完整的全长lipA基因。

The experimental results showed that both nylon 611 and nylon 611/montmorilonite were pseudoplastic and exhibited shear-thinning behaviors.

在恒定剪切速率下，蒙脱土的质量含量对体系剪切应力和表观粘度的影响相似。

At a constant shearing rate,the influences of montmorilonite loading on the shearing stress and apparent viscosity were similar.The reduction of the viscous activation energy with the increm...

PA611/蒙脱土纳米复合材料的粘流活化能随剪切应力的增大而降低，说明在恒定剪切应力下其可在较宽的温度范围内加工、成型。

The results of Pancherz analysis shows that the correction of negative overjet is mainly due to the advancement of maxilla and upper incisors. But the position changes of mandible and lower incisors imply that severe maxillary hypoplasia with high angle and/or mandibular retrusion is contraindicated by the method conducted in this study.

头影测量侧位片Pancherz分析法的分析结果表明，本研究中上颌后缩患者反覆盖的矫治主要由上颌骨、上切牙的前移引起的，但下颌骨和下切牙位置的变化提示适应症的选择应注意避免上颌后缩同时伴有高下颌角和／或下颌后缩的患者。

According to the morphological characteristics of cementite lamellae, the deformed pearlite can be divided into three kinds: irregularly bent lamella (pearlite lamella originally inclined with large angles to the rolling plane and irregularly bent after deformation); coarse lamellae with shear-band (the rhomboidal blocks of weakly deformed lamella bounded by shear band) and fine l...

按 渗碳体形态特点，变形珠光体组织可分为以下3种类型：(1)不规则弯曲片层型，即变形后的渗碳体与轧制面呈大角度偏离且不规则弯曲的珠光体。(2)带有剪切带的粗大片层型，即被渗碳体剪切带分开且变形轻微的珠光体。(3)精细片层型，即与轧制方向平行排列、片间距细小且渗碳体严重变形的珠光体。精细片层区域的比例随着轧制压下率的提高而增大。此外，重度冷轧变形还引起渗碳体严重塑性变形和部分溶解。
