难处理的

This paper contributes to experimental study and practice on treatment of organic wastewater by a new electrochemist reactor- bipolar packed bed cell.

本文是一种新型电化学反应器—复极性固定床电解槽(bipolar packed bed cell简称BPBC)处理难降解有机物的研究，对于难降解有机物处理技术的提高具有积极的意义。

It's a bit easier because you don't have to detect and configure your own hardware. Ironically, it's simultaneously harder because correctly handling Plug and Play and power management is fiendishly difficult.

简单的是您不必对硬件进行测试和配置，但难的是正确处理即插即用和电源管理，而且非常之难。

It includes the preparation of catalysts, chlorine dioxide catalytic oxidation high concentration organic wastewater containing naphthol green B and eriochrome black T.

本论文主要研究了二氧化氯催化氧化处理高浓度难降解有机废水新技术，包括催化剂的制备、催化氧化处理萘酚绿和铬黑T两种高浓度有机废水。

The motionless backgroup situation usually happens at the video camera parked to opposite quiescent condition , the first wipe off yawp by using pretreatment method,the second using the method of difference Statistic in two frame to analyse and compute background , Above this base to utilize the resumeed background and present frame message detect movement target and it"s movement track ; In dynamic backgroup movement image,it is very difficult to exactly compute ground since the background is varied complexly , the article research the optical flow model、 background model、 moving object detection based on entropy,and depart target from background in movement picture , detect moving target and plain it"s track.

静止背景的情况通常发生在摄像机相对静止状态，首先用预处理的方法去除噪声，其次采用帧间差分统计的方法进行分析计算背景，在此基础之上利用恢复的背景及当前帧的信息检测运动目标及其运动轨迹；对于动态背景的运动图像，由于背景是不断变化且呈现出复杂的特征，因此很难准确求出静止背景，本文在光流矢量场和配准方法的基础上探讨研究了光流模型、背景模型和基于熵的方法，在动态图像上分离不同的目标与背景，直接检测出运动目标并画出相应的轨迹。针对运动图像的复杂性，本文提出了构建模型知识库的设想。

L/h. All units in the process were controlled by a PLC system, while the on-line cleaning of the ultrafilter was realized by using an energy reservoir.

虽然能够达到处理水的要求，但是工艺路线较长、设备占地面积大，实现自动化控制和连续处理较难。

Dept.of Environ.Sci.Zhejiang Agricultural University,Hangzhou 310029）Abstract:The experiments on start-up of degrading-PCP anaerobic bioreactor carried out in two anaerobic bioreactors which were inoculated with unacclimated anaerobic sludge.

近年来，国外研究者基于厌氧微生物具有还原脱氯活性，已将厌氧生物工艺从用于处理一般有机废水，扩展到含氯代有机物等有毒难降解有机物废水处理及受污染环境的生物修复领域。

In order to achieve biological remediation of the pollution and improve the efficiency of treating refractory wastewater, purposive acceleration of the horizontal gene transfer of specific degradative gene will be a new concept to solve these problems.

为了实现污染地区的生物修复及强化难降解废水处理的效果，人为的制造和加快特定降解基因的水平转移被认为是解决这些问题的一个新思路。

However, iron precipitate could hardly be found by scanning infrared microscopy in the specimen annealed lower than 1100℃ so that iron-precipitation temperature in monocrystalline silicon or cast multicrystalline silicon could not be determined.

然而，用红外扫描电镜等很难观察到热处理温度低于1100℃处理过的样品中是否存在铁沉淀，所以无论是对于直拉单晶硅还是对于铸造多晶硅，很难确定铁的沉淀温度。

Long running performance showed that due to the membrane interception,the nitrobacter is enriched in reactor in the interest of improving the nitrification rate;the maximum ammonia nitrogen loading can be 0.19 kg/(m3·d) with effluent ammonia nitrogen＜1 mg/L (removal rate 99%).

焦化废水含氮量高且含有大量有毒和难降解物质，若采用传统生物处理工艺不但流程较长，处理效果也较难达到要求，而膜生物反应器通过膜分离强化了生物处理效果，克服了传统工艺的弊端［1］。

The news spokesman of company of game of a network says, the operation that builds Ci to use his really unplugs charity the height that reachs high to a very difficult look forward to, worth while study, but in fact Chinese system and beautiful state-owned difference, the IT plute that believes these China has his reflection and operation, just have not mature just, choose low-key processing now so.

一家网络游戏公司的新闻发言人称，盖茨确实用自己的行动将慈善拔高到一个很难企及的高度，值得学习，但事实上中国的制度与美国有差别，相信这些中国的IT富豪都有自己的思考与行动，只是尚未成熟而已，所以现在都选择低调处理。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
