查询词典 kerf

The results showed that the method of rubbing the kerf then injection of retrovirus suspension into pancreas could more effectively mark the pancreatic cells than the caudal vein injection and the intraperitoneal injection did in vivo. Furthermore, this study also found that some acinus cells could accept injury stimulus signals to regenerate through resuming mitosis after pancreatic injury.

结果发现在活体条件下，与尾静脉注射及腹腔注射法相比，胰腺伤口涂抹并胰腺内注射反转录病毒的方法能够更有效的标记胰腺细胞；而且，通过对标记细胞的世系追踪研究证明，在胰腺损伤后，胰腺腺泡细胞能够接受损伤信号刺激发生再生。

一系列的切缝宽度和曝光可能会改为优化的表现。

The effect of laser cutting parameters on surface roughness of kerf, splash and residue of kerf surface was studied systematically.

连续激光切割加工效率高，但对于薄板以及精密加工来说，采用脉冲工作方式，可以显著减小热影响区，提高切缝的表面质量[1] 。

The results showed that with the increasing of repetition frequencies, power density, and pulse width of laser beam and with the decreasing of scanning speed, the kerf quality could be improved. Besides, a formula of estimating the kerf surface roughness was also presented, which can explain the experiment results well.

在加工电子行业中表面组装用的模板时，一般采用化学刻蚀法，其缺点是加工精度低、工序多、周期长，特别是受刻蚀因子的限制，模板的最小缝隙宽度不能低于模板厚度的 1 2 ，因而难以满足日益发展的微电子技术对电子线路制作精度的要求。

A tunneling machine for producing large tunnels in soft rock or wet, clayey, unconsolidated or bouldery earth by simultaneously detaching the tunnel core by thermal melting a boundary kerf into the tunnel face and forming a supporting excavation wall liner by deflecting the molten materials against the excavation walls to provide, when solidified, a continuous wall supporting liner, and detaching the tunnel face circumscribed by the kerf with powered mechanical earth detachment means and in which the heat required for melting the kerf and liner material is provided by a compact nuclear reactor.

&…一个在软岩石，或湿的、粘土状的、疏松的，或巨砾泥土中挖掘隧道的隧洞掘进机，用先进的以上升暖气流进行隧道核心分离，将边界切口熔入隧道面，同时通过使偏倚在隧道壁上的熔融物料在凝固时提供一个连续墙来支持衬垫，形成一个支持挖掘的墙壁；破碎在切口周围划了界限的隧道核心-用有动力的机械土地分离的方法，在隧道核心中，需要如此操作的热力以及衬垫物料由一个小型的核反应堆提供……&

According to the calculation result of the imbalance response amplitude by XLROTOR,this paper analyzes and calculates the loss of saw kerf caused by the imbalanced amounts of main parts and makes this conclusion;To reduce the loss of saw kerf,it is more efficient to generally control the imbalance amounts cause by the different materials of main parts than to improve their tolerance.

依据XLROTOR的不平衡响应振幅计算结果，对主要零部件不平衡量造成的锯路损失进行了分析后得出；为了减少锯路损失，总体上控制各主要零部件因材质不均造成的不平衡量，比提高它们的公差等级更为有效。

Saw speed should be slowed down by step when kerf is not smooth in monitor of saw machine; If kerf touches or is over the edge of saw street, the saw blade should bechange.

在划片机的监视器上，观察到划片痕不平滑时，划片速度应该一步步降低；若划痕碰到或超过划片道边缘，则划片刀应该换新。
