This paper disc usses this according to the origin of “de”-verb-complement structure, the tre atment of the part behind “de” in current Chinese and the mistreatment of the sentence by SUN Yinxin.
本文从带“得”的述补结构“得”的来源上、现代汉语的“得”后部分的处理上、孙银新对“他打得孩子到处乱跑”的处理的几处不妥三个方面指出 :“他打得孩子到处乱跑”的确不宜处理为兼语句 ,而应该处理为“得”后补语句。
The projectile loom uses a small projectile to carry the filling yarn through the shed.
片梭织机利用一只小片梭携带纬纱穿过梭口
The result is that usually the warp shed must be larger than that for a shuttle loom.
纬纱会弯曲,这就要求喷气织机的梭口应大于有梭织机的梭口。
Normally, the shed starts to change long before the shuttle is completely out of the shed.
通常在离梭子出梭口之前还有很长一段时间时,梭口就开始变化(指梭口闭合)。
The projectile loom uses a projectile with grippers to carry the yarn through the shed.
片梭织机使用一个带有夹子的片梭将纬纱引过梭口。
In most cases it is possible to allow the shuttle to enter the shed before the opening of the shed in front of the reed is as large as the shuttle size.
在大多数情况下,当钢筘前面的梭口尚小于梭子大小(指横截面)时,便可能使梭子进入梭口。
shedding: separating the warp threads into two layers to form a shed.
开口运动：将经纱分成两层,以形成梭口。
This is to avoid beat - up with the shuttle trapped between the two warp sheets or having a very weak pick the next time around.
这样可以避免梭子依然还在梭口当中时进行打纬,也可避免在下次投梭时投梭力不足。
the front moves slower than the rear and the yarn buckles. The result is that usually the warp shed must be larger than that for a shuttle loom.
纬纱前端的速度低于后部的速度,纬纱会弯曲,这就要求喷气织机的梭口应大于有梭织机的梭口。
The timing of the opening of the fully open shed is important.
梭口全开的时间是很重要的。
picking: passing the weft thread, which traverses across the fabric, through the shed
引纬运动：将纬纱沿织物横向引过梭口。
The shed has to be sufficiently opened and remain open long enough for the shuttle passage.
为了便于梭子的通过,梭口必须充分开启并保持一定的静止时间。
Physical laws dictate that, to move through the shed, the shuttle must be accelerated and decelerated. This naturally takes time and energy.
物理定律指出,要想使梭子穿过梭口,梭子必须被加速和减速,这当然需要时间和能量。
At the time the two sheets of warp become level, the shed is said to be closed.
在两页综框平齐时,梭口被认为是闭合了。
In an air jet loom, high pressure air carries the filling yarn through the shed.
在喷气织机上,高压气流携带纬纱穿过梭口。
Up to now, all the dobbies either home- made or imported are almost all of symmetrical shedding type.
直至今日在我国所有生产和进口的多臂属于对称梭口。
The projectile does not have to carry a yarn package with it and it needs only be relatively light in weight; however, it is sufficiently massive to be unaffected by minor obstructions in the warp shed.
片梭不必携带纬纱卷装,其重量相对较轻,但是其质量已足以使它能免受梭口中微小障碍的影响。
If less time could be spent accelerating the shuttle, and the transit time of the shuttle through the shed could be reduced, higher loom speeds could be obtained.
如果减少给梭子加速用的时间,而且梭子穿过梭口的时间也能减少,织机便可以以较高的速度运转。
