Plastic should lower 3 steps, because plastic is a step to add melt resin material to cyclinder , Higher stick of resin material ,higher screw back pressure. Screw speed differs depending on decomposing temperature of resin material ,Higher screw speed ,Higher trim force of resin, higher cyclinder temperature. Some resin material may decomposes so it set screw speed in mid-speed such as 45-75%, In plastic step setting screw back pressure is very important, Higher screw back pressure ,higher quality of product screw back pressure make resin structure order, Molding product is beautiful and volume stable. But ,it maybe flow if screw back pressure too high .

再复杂的熔胶旋转过程最多不会超过三段，因为熔胶本身就是存在于把胶熔进料筒的过程，半夜盗汗897就去播播Z如果原料粘度大，熔胶压力则大，但速度则应取决于原料的分解温度，熔胶速度越快，原料中的剪切力则会越大，料管温度则越高，局部原料产生分解的可能性则会越大，故一般熔胶会采用中速为宜，如45%-75%，熔胶同时会碰到一个比较重要的环节，那就是背压的使用，产品精度要求越大，背压的使用则更大，背压可使原料分子间结构更紧密，成型出的产品则尺寸更稳定，外观越好。

The arguments on the necessary for quantized evaluation toward quality of services of multicast in Overlay networks are given. The concept of twodegree homeomorphism reduction multicast tree is introduced, extend Bowman's method for evaluating QoS of unicast dataflow by using stochastic process algebra is promoted, a modeling scheme is proposed for quantized evaluating QoS of concrete multicast instances in Overlay networks with simulation tool PEPA workbench.

结果表明，间作和同穴混播豆田的病虫发生危害轻于纯作豆田，与纯作比较，间作田和同穴混播田主要害虫降低率分别在11.4%？81.4%和20.9%？76.0%之间；其病害降低率分别为70.0%？

After broadcasting, narrowcasting, podcasting, screencasting, simulcasting, netcasting, multicasting, Zunecasting, Bluecasting and typecasting I thought, frankly, I was inured to anything ending in casting, but surprisingly I've found one more I'm quite enthused about.

在经受了广播、窄播、网播、屏播、同播、组播等等的狂轰滥炸之后，坦白讲我以为自己对任何跟"播"沾边的词都已无动于衷了，但出乎意料的是我又发现了一个令我激情澎湃的"裤兜播"。

In this paper, a CWE model of the distance education system is provided. In order to enhance the bandwidth utilization factor, a transfer method based on multi-channel is presented. Both the transmission of real-time media stream and time-stamp technologies are introduced to the system to ensure the requirement of real-time characteristic and synchronism, and a simple protocol based on RTP (Real-time Transfer Protocol) and UDP is designed. The method, event simulcast, is also brought forward to reduce the data redundancy and expand the collaboration scale of the system.

本文给出了远程教学的协同工作环境模型；设计中为了提高系统带宽利用率，采用一种更符合实际应用要求的"单播+广播"的有效通信方式；为了解决音视频同步问题，参考实时媒体流和时间戳同步技术，设计了一个基于用户数据报协议UDP和实时传输协议RTP的简单传输协议，实际应用中保证了数据的实时性和同步性；系统采用基于显示同播的事件同播方式，这样在一定程度上降低了数据冗余，同时扩大了系统的用户数量。

There are three problems which must be solved in the construction of the 198/199 network, because of its high-speed and vast-region:simulcast interfering in the simulcast area;communication interruption between paging zones;signals of multi-frequencies switching invalidation between simulcast systems.

由于广域高速寻呼网络的技术特点，在198／199网络的建设设计和运营中要着重解决三大技术问题，即：同播区内的同播干扰问题；寻呼区间的IPNP联网障碍；以及同播区间的FLEX多频漫游信号切换障碍。

And the solutions of the three problems above are discussed:The solution to the simulcast interfering which is caused by the simulcast delay spread and the zero-beating is given in chapter four.Based on the well understanding of the principle of MS-I/H/0 in IPNP, the examples are given in chapter five on how to solve the problem of communication interruption between paging zones.Through the analyse of signal switching between Chengdu and Deyang, the synchronization error between FLEX frames, and the bug in the multi-frequency roaming principle are pointed out. And solutions are also recommended.

通过以上分析，文章探讨了对上述三个问题的解决：·对同播干扰问题，分别分析了时延差和零拍频所造成同播干扰的客观存在，探讨了系统设计和网络优化的基本方法；·对IPNP联网障碍，提出了在掌握IPNP对各PNCC作为输入局／归属局╱输出局的灵活定义、以及相关参数配置原理的基础上，分析联网障碍的思路；·对信号切换障碍，以成都和德阳两地的局部广域覆盖为例，分析了FLEX帧失步和FLEX多频漫游原理设计缺陷的客观存在，并探讨了相关的解决方法和建议。

Being a protective tillage, the no-tillage means getting rid of not only the tillage before sowing, but also the intertill after sowing, and leaving the plant residue after harvesting.
