查询词典 step

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。

Besides, because of diversity of biochip image, the shape of some spots can not be uniformly circular. Solved the problem of coarse segmentation and modification of deflexion angle, a method of tracking local spots profile—Template snake model has been proposed in the paper, it can recognize the target from roughness to precision step by step, so to guarantee the precision and efficiency of segmentation.

此外，由于生物芯片多样性特点，某些芯片样点外形并不一定是简单的孔径问题，本文在比较彻底地解决了样点粗分割及偏转角校正后，提出了局部区域的样点轮廓跟踪方法——Template snake模型，实现由粗到精的宏状多目标分层识别策略，既保证了样点分割的正确率，又加快了执行速度。

The first step ranges from 250 to 380 ℃ with a weight loss of about 3%, resulting from the denaturalization and decomposition of organic matter in the powder;and the second step from 600 to 780℃ with a weight loss of about ...

第一阶段在 2 5 0～380℃，失重率约 3 %，此为有机质变性与分解阶段；第二阶段在 6 0 0～ 780℃，失重率约为 40 %，为碳酸钙的分解阶段。

As the pyrolysis technology for MSW, comparing with incineration, has a higher WTE and lower second-step pollution, it has been considered a more advantages MSW deposal technology than incineration. However, it is only in its preliminary step. Till now, there is quite limit successful practical pyrolysis technology applying on MSW and deficient of relative fundamental research on them. So to do some fundamental research about this is both very important and very necessary.

由于固体废弃物热解技术具有比焚烧法更高的能源利用率和较低的二次污染，因此被认为是比焚烧技术更先进的废弃物处理技术，当然，固体废弃物热解技术发展目前还处在起步阶段，迄今为止，已成功应用于处理城市固体废弃物的热解技术还非常有限，与之相关的很多基础研究还很缺乏，因此对固体废弃物热解技术的有关基础研究是十分重要和必要的。
