切

" Zhang Baoquan says,"When average person cuts an apple end up is cut, nucleus of the apple after incision is nuclear; I cut an apple to want sidewards to cut, the nucleus after opening an apple can present the appearance that gives five-pointed star, this is malic heart.

&张宝全说，&一般人切苹果时都竖着切，切开后苹果核就是核；我切苹果要横着切，打开苹果后核会呈现出五角星的形状，这就是苹果的内心。

The expression of p-p38 and Rho GDIαwas upregulated in LCA by either low shear stress or hypertension. However, the highest expression of p-p38 and Rho GDIαwas observed in LCA of low shear stress accompanied by hypertension.(4) Effect of low shear stress on both decreasing apoptosis and increasing proliferation of VSMCs in LCA was reversed by tributyrin, a HDAC inhibitor.

当高血压伴有低切应力时，两者的协同作用诱导p-Akt的表达水平进一步增加；(3)高血压和低切应力都可以诱导颈总动脉p38和Rho GDIα表达增加；当高血压伴有低切应力时，两者的协同作用诱导颈总动脉p38和Rho GDIα表达进一步增加；(4)HDAC抑制剂Tributyrin可以通过抑制VSMCs增殖，促进VSMCs凋亡，在干预低切应力诱导的血管重建中发挥作用。

According to this phenomenon, we analyze the original circuit structure of unreasonable, in the original circuit has added a intermediate relay (5J), a limit switch, and take advantage of the original paper cutting, the unused in the buttons on the normally closed contact, specifying the control switch some of cam shape change, so that you solve the Cutter knife to cut the ?

根据这种现象，我们分析了原电路的不合理结构，在原电路中添加了一只中间继电器（5J）、一只行程开关，并利用了原切纸按钮中未用上的常闭触点，同时将控制行程开关的凸轮形状稍加改变，这样就彻底解决了切纸刀切下后自动复位难的问题，使切纸速度达到了要求的次数。

Axotomized, turn the paper of the cam disconnect switch on the side of the circuit, forcing 3XK press paper cutter and a loss of power, but the operators have not yet had enough time to release the button, turn the paper cutting of the cam over the limit switch 3XK, 4J and 1 c was electric pick-up, gnashing paper cutter does not reset, in this case, a rotating cam on the other side lost your limit switch XM, intermediate relay 5J load-disconnected.

纸张切断后，转动的凸轮一侧断开行程开关3XK的回路，迫使压纸和切纸断电，但是操作者还未来得及松开切纸按钮，转动的凸轮滑过行程开关3XK后，4J和1C仍得电吸合，造成切纸刀不复位，这时，转动的凸轮另一侧断开了行程开关XK，中间继电器5J失电断开。

The database of judging chip break is founded, which is based on the characteristic of chip breaking curve.

通过切削试验，获得了刀具主偏角、切削速度和工作材料牌号对切屑的极限进给量和极限背吃刀量的影响规律及其经验公式，并根据切屑折断曲线建立了判断切屑是否折断知识库和切屑折断预报系统。

Predicting the up-curl chip breaking of three-dimensional groove inserts;2. The database of judging chip break is founded, which is based on the characteristic of chip breaking curve.

通过切削试验，获得了刀具主偏角、切削速度和工作材料牌号对切屑的极限进给量和极限背吃刀量的影响规律及其经验公式，并根据切屑折断曲线建立了判断切屑是否折断知识库和切屑折断预报系统。

For the problem of breaking stalk with hit shear type and stubble with double shafts, the principle of press chop type with single shafe and the models of chopping with knife of different radius are put forward.

针对双轴击切式破碎秸秆和根茬所存在的问题，本文提出单轴压切原理和非等长刀切碎模型，并对秸秆切碎灭茬机的关键参数进行了优化设计。

In the cutter in use and in order to maintain the blade of the sword cutter, extended service life, once the best cut-paper thickness should not exceed 40 mm, and cutter on paper pressure should also be appropriate, and generally soft paper need pressure larger, harder materials require relatively little pressure.

在切纸机使用中，为了保持刀片的锋利，延长切纸机的使用寿命，一次裁切的纸张厚度最好不要超过40mm，而且切纸机对纸张的压力也应适当，一般较软的纸需要的压力大一些，较硬的材料需要的压力相对要小一些。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
