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.
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,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。

According to the method of checkout and identification complying with laboratory quality control rules, we made the calibration tests on CEMS smokemeter. After the linear regression analysis of test results, we verified the correlation coefficient was more than 0.99 between FW56-1 smokemeter, which was made by ABB, Germany, and TH-880IV smokemeter, so the high measurement accuracy was confirmed. Moreover, with less than 90% stained space of lens, this instrument can still work accurately, so the probe has big pollution tolerance. It can totally meet the request of pollution online monitoring.

To reduce and compensate the influence of temperature on ring laser gyro bias error and attain the precision of inertial level gyro, the mechanism of RLG zero-bias error due to temperature is analyzed. Based on a great number of environmental temperature experiments of RLG, a general temperature compensating model and a new kind of BP neural network model are established. A method for identifying the model parameter is proposed. Simulation results show that the simplified compensating model can reduce the zero-bias by more than a magnitude and achieve real-time compensating feature.

Therefore we have optimized the experimental system and the working status of instrument.2 The near-field SERS spectra and images for the [Ru_3]~(2+) molecule adsorbed on silver nanoparticle substrate were achieved. Based on the results, some specific phenomena for near-field SERS were found. By observing the near-field SERS spectra collected at different location at the nano-scale, the different spectral characteristics which are caused by the local environmental differences of molecules have been found. On the substrate, the highly SERS active sites are much more than SEF hot spots, and the distribution of them is not entirely consistent. This phenomenon could be explained by the influences of several factors including the different enhancement efficiencies existed for SERS and SEF, the quenching effects for fluorescence by the metal substrate and metal-coated tip, and the presence of different numbers of probing molecules in SERS and SEF.3 It is of interest that the near-field and far-field SER spectra demonstrate several distinctively different spectral features.
由于SNOM与SERS的结合在技术上将面临很多实际困难,例如近场激发信号极其微弱、纳米级微弱光谱的收集对实验精度和环境稳定性的苛刻要求等,因此我们对实验体系和仪器工作状态分别进行了优化。2获得了银纳米粒子SERS基底上[Ru_3]~(2+)分子在纳米尺度下的近场SERS光谱和图像,从中可以发现一些近场SERS效应特有的现象:通过观察不同位置得到的近场SERS光谱可以发现,在纳米尺度下,由于分子所处局域环境不同而体现出不同的光谱特征;此基底具有极高SERS活性的位点远多于表面增强荧光热点,且两者的分布并不完全一致。
