As a consequence, a mechanism assumption of impact of sawtooth-shaped burr and finshaped chip edge was proposed.

研究证明限制陶瓷刀具使用寿命的主要因素是快速发展的边界沟槽磨损。

PCFK series of pairs of counter-reversible hammer crusher is a new crushing equipment, mainly by knock-on effects to broken materials, broken process in general is this: the material falling into the break in the world, imported high-speed rotation of the hammer impact face was against the entrance of the adjustable crusher tooth wear plate, for the first time broken, broken after the particles basically the same material evenly into the main break, the secondary primary crushing, crushing in the main chamber has been uniformly The material was re-kinetic energy particles from the hammer, high-speed rushed back inside the jagged cavity lining was broken, due to the special lining sawtooth-shaped structure.

PCFK系列可逆双反击锤式破碎机是一种新型破碎设备，主要是靠冲击作用来破碎物料的，破碎过程大体是这样的：落下的物料进入破世界进口后，遇到高速旋转的锤头冲击而被打击到破碎机进口处的可调耐磨齿板上，进行首次破碎，破碎后颗粒基本相同的物料均匀的进入主破碎内，进行二次主破碎，在主破碎腔内已被均匀的物料颗粒从锤头再次获得动能，高速冲向反击腔内部的锯齿形衬板而被破碎，由于衬板特殊的锯齿形结构。

As a result,the ray tracheid inner wall has sawtooth thickening obviously.The pit of cross field is windows and pine shape.The ratio of the tracheid length to width is about 50.Airdry density is about 598kg/m3.The shrinkage of difference is about 1.8;1%NaOH extraction and cell...

结果表明：紫杉木材射线管胞内壁锯齿状加厚明显，交叉场纹孔多为窗格状，偶尔为松型；管胞的长宽比平均值约为50，气干密度平均为598kg／m3，差异干缩约为1.8；1％NaOH抽出物、乙醚抽出物、纤维素含量较落叶松高，木素含量比落叶松低，其它化学指标与落叶松相近。

I can bend the front of the Expert Mids backwards, almost folding the boot in half, but the Sawtooths have a very stiff midsole that provides some of the best stability and support I've felt in a boot of this kind.

我可以将 Expert Mid 的前面朝后弯曲，几乎将整只鞋对半折，不过 Sawtooth 的中底非常硬，它提供了同类鞋子中我觉得是最好的稳定性和支撑。

The image of the hot core and cold bubble is similar to Wesson model in the late period of the sawtooth. Wesson's model process is a domain effect during sawtooth process.

在锯齿发展的后期热心和冷泡的图象是与Wesson模型相似的，Wesson模型描述的过程占主导作用。

Figure 2 shows the jigging concentrate relations between content and ore feeding volume, when the diaphragm jig and the sawtooth pulsation jig are provided with different ore volume. Figure 3 shows the jigging concentrate relations between the sulphur recovery rate and ore feeding volume. As the test result shows, when the tailing content reaches approximately 7%, the diaphragm jig has 1.00 t / h · m2 feeding volume, which is also the maximum sorting efficiency in the test. As such, the sawtooth pulsation jig could choose 1.2 t / h · m2 feeding volume. As the test contrast of two groups shows, the sawtooth pulsation jigging concentrate contains higher-grade sulphur than the diaphragm jigging concentrate does.

图2为隔膜跳汰机及锯齿波跳汰机在不同给矿量的情况下，跳汰精矿品位与给矿量的关系，图3为跳汰机精矿硫回收率与给矿量的关系，试验结果表明，在尾矿品位接近7%，隔膜跳汰机给矿量为1.00 t/h·m2指标是隔膜跳汰机给矿量试验中选别效率最高的点，同理选择锯齿波给矿量为1.2 t/h·m2，将两组试验数据比较可以看出，锯齿波跳汰精矿含硫品位高于隔膜跳汰精矿含硫品位。

Are given out, and then a survey and review of the literature up to 1980 is given of the linear theory of the ideal and resistive hydromagnetic instability of tokamak. Some important characteristics of MHD instabilities are discussed in more details. Since sawtooth oscillation is discovered in ST tokamak, many theory models are proposed to explain the disruptive part of sawtooth, however, there is no satisfactory theory of the internal disruption.

本论文对锯齿振荡和L-H转换作了研究，主要开展的工作如下：在论文的开始部分，给出了基本的MHD方程，对至1980年文献水平的托卡马克中理想和电阻性情况下的磁流体不稳定性的线性理论作了简要回顾，讨论了某些重要的不稳定性特征。

The Sawtooth boots shown here are priced very reasonably ($90), but has some of the design features of the more expensive, heavyweight hiking boots.

所示的 Sawtooth 靴子价格合理($90)，但是有些具设计特点的款式会贵点，也重的攀岩靴子。

The Sawtooth boots shown here are priced very reasonably ($90), but has some of the design features of the more expensive, heavyweight hiking boots.

图中展示的 Sawtooth 定价非常合理（90 美元），但在设计上包含一些更贵、极重的徒步鞋才有的特点。

The test locales included the Sawtooth Mountains, Idaho; canyons, peaks, and deserts in Arizona; Washington's North Cascades; an island off the coast of British Columbia; the North Slope of the Brooks Range, Alaska; Half Dome in Yosemite, California; and almost everywhere there's a trail in the Northeast.

测试地点包括爱达荷州Sawtooth山脉；亚利桑那州的峡谷、山顶、沙漠；华盛顿的North Cascades；英属哥伦比亚海岸附近的一座孤岛；阿拉斯加布鲁克斯山脉北坡；加利福尼亚约塞米蒂国家公园的Half Dome；全部的旅行几乎遍及了东北部的各处，我们扛起适合全家的装备，携带滑雪板，攀登岩石，蹒跚而行穿越了Arctic（北极地区在北极与北美洲和欧亚大陆北部林木线之间区域）草丛地带，托运了无数加仑的水。
