Basing on many kinds of different ways, and referring to some experience about particles removal, this article fixes on a route, which adopts fiberglass — PTFE bag filter to depurate the gas.

通过比较多种不同工艺，并借鉴国内外烟尘治理经验，本文确定对烟气进行预处理后，用玻纤覆膜滤料袋式除尘器对工业硅矿热炉产生的烟气进行净化。

The cardboard boxes sitting shrink-wrapped in NYK Logistics' dimly-lit warehouse in Shanghai look unexceptional.

在日邮物流灯光昏暗的上海仓库里，经过覆膜包装的纸箱看起来没什么特别。

When the soil surface is fully mulched with plastic film, salt concentration is a exponential function of depths. With different film hole ratios and wetting fronts depths, the salt concentrations can be expressed as a discontinuous function of the depth.

对不同开孔率来说，全覆膜蒸发的浓度可用深度的指数形式表达，不同入渗锋和开孔率条件下浓度可表示为位置的分段指数函数。

In order to know the effects of mulch-drip irrigation on soil enzyme activities of saline-sodic soil with shallow water table, activities of alkaline phosphatase, urease, and invertase around the dripper, within 30 cm in horizontal direction and 40 cm in vertical direction from the dripper during the reclamation process, were investigated. Changes and distribution of soil enzyme activities, also their relationships with principal soil environment factors were studied.

为了解地下水浅埋区重度盐碱地覆膜滴灌对土壤酶活性的影响，测定了重度盐碱地在滴灌利用过程中距离滴头不同水平位置（0～30 cm）和垂直深度（0～40 cm）的土壤碱性磷酸酶、脲酶和蔗糖酶活性，并对土壤酶活性的变化、空间分布特征及与土壤环境因子之间的相关关系进行分析。

To carry out different substrate, electrothermic resin coated steel drum of temperature must be based on the ehuobulake product.

对不同承印物进行覆膜时，电加热钢滚筒的温度必须根据所覆产品来调节。

By applying parallelogram linkage principle, we developed a new planter that accepted seeds erectly, inserted and pulled out of soil vertically.

为满足覆膜穴播的农艺要求，获得满意的作业效果，必须寻求新的成穴原理和成穴器结构[1，2 ] 。

Comparing with the two methods, spraying method will make carbon nanotubes well dispersed in the plastic surface and the conductive surface of the obtained materials will be evener and more stable.

结果表明：两种方法制成的抗静电覆膜都能大大降低塑料的表面电阻，但喷涂法更能使碳纳米管在塑料表面均匀分散，从而使塑料表面抗静电性能更加稳定。

The product series of coated sand efficiently solved the problems: insufficiency of organic binder in high temperature, high expansivity of natural silica sand and much gas of coating of organic molecular in high temperature.

覆膜砂系列产品有效解决铸造材料有机粘结剂高温性能不足，天然硅砂热膨胀率高和有机高分子高温汽化发气量大的关键技术难题。

If too high a temperature section covered with film, Fizz.

如果覆膜温节过高，就会起泡。

The surface appearance and hygroscopicity of ADN after coating were analyzed by SEM and weighing method. Results show that a kind of floccule of PU is formed on the surface of ADN, which makes the hygroscopicity of ADN after coating less than that before coating evidently. When coated ADN is exposed in the atmosphere for 30 days with the RH less than 60%, the hygroscopicity of coated ADN is only 0.136% and does not increase with the increasing of exposure time.

用扫描电镜和称重法分析了包覆后ADN的表面形貌和吸湿性，结果表明，聚氨酯黏合剂在ADN表面形成絮状的包覆膜，使包覆后ADN的吸湿率明显小于包覆前ADN，在相对湿度60%以下，包覆后ADN在空气中暴露30天时吸湿率仅0.136%，吸湿率不随时间增加。
