Six are a wide range of applicability and flexibility, can be used in Daejeon, economic crops, vegetables and orchards; are seven gate opening set, from the beginning to the end of irrigation, without manual operation, greatly reducing labor irrigation to improve water working conditions; are eight gates to control irrigation systems and drainage Irrigation District, full-motion can also be used as pipe to replace the fields of agricultural,毛渠,斗渠to achieve from畦沟with water, can also be used as surge irrigation water distribution pipes at the end of class .

六是具有广泛的适用性与灵活性，可用于大田、经济作物、蔬菜和果园；七是闸板开度设定后，从开始到灌水结束，无需人工操作，极大地减少灌水用工，改善灌水的工作条件；八是闸管灌溉系统可与渠灌区、也可用作全移动管道输水，替代田间农、毛渠，完成从斗渠到畦沟配水，还可用作波涌灌溉的末级配水管道。

Leaf blade lobes finely divided; ultimate lobes of leaf blade linear-lanceolate to narrowly linear.

叶片裂片细裂；叶片线形披针形到狭线形的末级的裂片。

Leaves 2 or 3 per ultimate branch; auricles minute or absent; oral setae short; ligule exserted; blade ca. 12 × 1.4 cm. Flowering branchlets spicate, ca. 8.5 cm, scaly bracts ca. 4, gradually larger; spathes 4 or 5, glabrous or sparsely puberulous; auricles and oral setae absent, blade subulate, small.

每末级的分枝留下2或3；叶耳小或无；口头的刚毛短；叶舌外露；约叶片1.4 厘米花小枝12×穗状，约厘米，约有鳞苞片，逐渐大；佛焰苞4或5，无毛的或疏生微柔毛；叶耳和口头刚毛无，叶片，小。

Leaves 3 or 4 per ultimate branch; auricles absent; oral setae deciduous, purple; ligule moderately exserted, purple-red; blade 8–17 × 1.2–2.1 cm. Flowering branchlets spicate,(2.5–)5–6(–8.5) cm, scaly bracts 3–5; spathes 5–7, pubescent; oral setae 1–3, short; blade small.

每末级的分枝留下3或4；叶耳无；口头的刚毛落叶，紫色；适中外露的叶舌，紫红色；叶片 8-17 * 1.2-2.1 穗状的厘米花小枝，(2.5-)5-6(-8.5)厘米，有鳞苞片3-5；佛焰苞5-7，短柔毛；口头的刚毛1-3，短；叶片小。

While a ball mill is working, balls in the mill are lifted, and then are thrown away with a certain velocity to collide raw material. But at the same time, balls and underboarding are also got collision which may make balls and underboarding fracture. Considering the tough lubrication condition and dust and prills have easy access to meshing zone of gears, the heavy abrasion on gear surface often appears in the upstage gear of open-gear transmission of ball mill.

当球磨机正常运转时，磨球被提升到一定高度后抛落，以一定的速度对物料产生冲击而粉碎物料，同时也对磨球和衬板自身产生冲击，这可能造成磨球和衬板的破球磨机的末级开式齿轮传动，由于润滑条件差，粉尘、金属颗粒容易进入啮合区，齿面常常出现严重磨损，导致齿廓形状发生变化，最后因齿厚磨损过多而折断。

Leaves 2 or 3 per ultimate branch; auricles and oral setae deciduous; ligule purple-brown; blade 7–16 × 1.2–2.5 cm, abaxially proximally pilose.

每末级的分枝留下2或3；叶耳和口头的刚毛落叶；叶舌紫褐色；叶片 7-16 * 1.2-2.5 厘米，背面下部。

Mm, glabrous; blade reflexed, linear-lanceolate, glabrous. Leaves 3 or 4 per ultimate branch; sheath margins initially ciliate; auricles purple, falcate, small; oral setae erect, gray-brown; ligule arcuate, margins initially ciliate; blade lanceolate,(7–)10–16 × 1–1.7 cm, proximally white-gray pubescent, secondary veins 4-paired, transverse veins obscure, base cuneate, one margin spinescent-serrulate, other margin obscurely so.

每末级的分枝留下3或4；鞘边缘最初具缘毛；叶耳紫色，镰刀形，小；口头的刚毛直立，灰棕色；叶舌弧曲，最初给纤毛虫镶边；叶片披针形，( 7-)10-16 * 1-1.7 厘米，下部白色灰色短柔毛，4配对的次脉，不明显的横向脉，基部楔形，具刺有细锯齿的一边缘，如此的其他边缘不明显。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
