Otherwise existence of the phosphate, perchloride and nitrate ions can reduce the rate of chromium removal by zero valent iron in commercial powder iron system.

研究结果显示当六价铬中含有氯离子和硫酸根时能增加商业铁粉对六价铬的去除效果，而硝酸根、过氯酸根及磷酸根则会使商业铁粉去除六价铬的效果变差。

Tuber A swollen underground stem or root that contains stored food and acts as an organ of perennation and vegetative propagation.

块茎，球根：储存有大量养料的膨大的地下茎或根结构，为多年生器官同时也是营养繁殖器官。

First,we perfuse puerarin to the brain slice which electricity activity is better,one concentration per one brain slice,the result shows that the puerarin has conspicuous depressant effect to the hippocampal,s spontaneous discharge act,the mian abaissement modality is to cut down the frequency,but the effect to the amplitude is very little.

首先，在电活性较好的脑薄片上进行单一的葛根素灌流实验，结果表明，葛根素对海马神经元的自发放电活动有很明显的抑制作用，其抑制方式主要是降低了了海马神经元生理电的发放频率，而对发放的幅度影响则很小。

Second we use excitability medicine to provocat the nerve,s causality discharage,after 1 to 2 minutes,perfuse the brain slice with a certain concentration of puerarin to be abaissement,in result,we find that some kinds concentration(such as 1:1000) of puerarin have prominen depressant effect to the provocated discharage of the hippocampal nerves.

之后，通过在电活性较好的脑片上先进行兴奋性药物的诱发，待诱发性放电出现后1-2分钟再灌注一定浓度的葛根素进行实验观察，结果表明，一定浓度的葛根素(如1：1000)对海马神经元的诱发放电活动有显著的抑制作用。

Lateral root Any ROOT that arises from the PERICYCLE of another root.

侧根：起源于根的中柱鞘的根。

Anatomy observation was employed in sugar beet Rhizomania and the results showed:(1) The periderm construction of mot developed abnormally, the surface was not slippery and the cell arranged irregularly. Some of them were scraggly, cleft and some broke off, even some cell wall became brown.

对甜菜丛根病病根进行解剖学观察研究，结果表明：根部结构发生较大变化，(1)根的周皮结构发生异常，周皮表面不光滑，细胞排列不规则，有的凸凹不平，有的产生裂口，有的细胞脱落，细胞壁褐化等。

The results showed that POD activity increased at first and then decreased in the skin and flesh of root. The peak occurred at 40 d and 60 d in the skin and flesh, respectively. POD activity in the skin was higher than that in the flesh at 30 d and then contrary results were observed. The higher POD activity was, the more POD isoenzyme was. The pattern of POD isoenzymes was different between skin and flesh at different vegetative growth stages. POD isoenzymes in the skin were composed of five monomers and four dimers while five dimers or two monomers, two dimers and one tetramer in the flesh. POD isoenzymes in the root were mainly acidic. POD localized mainly in the cell walls of periderm, cambium, xylem ray, xylem vessels and primary xylem.

结果显示，心里美萝卜营养生长期肉质根的皮和肉中POD活性均先升高后降低，分别在播种后第40 d和60 d出现峰值，30 d时皮中POD活性高于肉，之后则相反，酶活性最高时同工酶数目也最多，不同时期，皮和肉中同工酶种类不同；皮中POD同工酶由5个单体和4个二聚体组成，而肉中由5个二聚体或2个单体、2个二聚体和1个四聚体组成，均以酸性同工酶为主；组化定位显示POD主要分布在肉质根的周皮、形成层、木射线、木质部导管和肉的初生木质部等的细胞壁附近。

In order to concern the tax system change resulting in economic structure transformation, the Unit Root Test adopts in the research is the Perron (1989) Unit Root test which considers the variable structure transformation.

为考量税制改变可能造成经济体结构转变的情形发生，故在单根检定时特别采用Perron(1989)考量变数结构转变之单根检定。

Firstly, the research tests the stationary of each variable by adopting the Unit Root Test and all variables shows I(1) sequence. Secondly, it tests the stability of each variable by adopting Perron (1989) structure transformation Unit Root Test. The test result is same as the ADF test, which does not consider the structure transformation.

首先以单根检定法来检定各项变数是否为定态，结果显示变数皆为I(1)序列，接著以Perron(1989)结构转变的单根检定，检测各变数的平稳性，检定结果与不考虑结构转变的ADF检定结果相同。

A study on the anatomical structure and the barbloin's store place of Pulsatilla chinensis of different growth lengths by anatomy and barbloin histochemical localization shows that multicellular nodulos, secretory cavities and secretory ducts in phelloderm and secondary phloem are the primary place of the barbloin substances and the major structural characteristics, wide or narrow of the secretory ducts is related to the growth length, 4 to 5 years old reaches maximum.

利用解剖学和组织化学定位方法对不同生长龄白头翁根的解剖结构和皂苷的储藏场所进行了研究。结果表明：栓内层和次生韧皮部中的分泌细胞团、分泌腔和分泌道是白头翁根的主要结构特征，是皂苷类物质的主要贮存场所；而分泌腔和分泌道的数量及分泌道的宽窄与生长年限相关，4~5年生达到最大值。
