The paper fristly compared the fertile soil with the incinerated sterile soil on the number of micro-algae , soil pH value , soil organic matter soil available phosphorus and soil nitrogen.And then, the author put fertile soil, which included micro-algae, proportionally into sterile samples and cultivated them respectively under illumination condition (micro-algae can live and reproduce)and dark condition(micro-algae will die in some time).The above indices were measured in 0, 30, 60 and 90days respectively, The analyse of the interrelation between the change of micro-algae"s number and the changes of soil pH value, soil organic matter, soil available phosphorus and soil nitrogen indicated:Soil micro-algae which were native to fertile soil conld adapt to the changed circumstance and light acted as a decisive role to the distribution of soil micro-algae.Under dark condition,the micro-algae"s number declined gradually and went to zero in the end,while under illumination condition ,on the 90th day, the micro-algaes number of per gramme was 6-7 times more than that of the beginning.

本文首先对肥沃土壤与经高温焚烧后的贫瘠土壤中的微藻数量、土壤pH值、有机质含量、有效磷含量和全氮量进行比较研究，然后将包含微藻的绿化苗圃地肥土按不同比例接种进入贫瘠土样中，分别在光照条件和黑暗条件下进行培养，在0天、30天、60天和90天分别检测以上指标，比较有光条件和无光条件下，即有藻条件和无藻条件下贫瘠土样所发生的变化，并分别对微藻数量的变化与土壤pH值、有机质含量、有效磷含量和全氮量的变化之间做相关性分析，以评估肥沃土壤中的微藻接种进入贫瘠土壤后的生长情况以及对贫瘠土壤的改良作用。

Preparation of ratiometric pH nanosensors and its appication in intracellular pH detection of the anti-tumor drugs treated Hela cells The ratiometric pH nanosensors that contained a pH sensitive indicator fluorescein isothiocyanate and a reference dye tris(2, 2′-bipyidyl) dichlororuthenium hexahydrate had been prepared with O/W microemulsion method.

利用该内参比pH纳米传感器尺寸小可以通过细胞的内吞而无损伤地进入细胞内的优势，进一步结合流式细胞学分析方法，对不同抗肿瘤药物作用的Hela细胞内的pH变化进行了分析，结果表明：不同抗肿瘤药物作用后的Hela细胞内pH的变化情况并不一样，有的作用后引起了细胞酸化，有的作用后引起了细胞碱化，有的作用后基本上不引起变化。

Implicit learning is a unconscious process which produces pure knowledge and runs parallel with explicit learning way,namely learners unconsciously grasp some mutative rules behind irritative environment,but they cannot accordingly realize what they acquire.

内隐学习是一种产生抽象知识、平行于外显学习方式的无意识过程，也就是指学习者无意识地掌握刺激环境中的某些变化规则，却没有伴随着相应的对所获知识的觉察。

One was that research objects were ruleless and dishevelled. Another was that research target was reducing Ommission Error of change parcel. The Distance Discriminate Analysis was meliorated in the paper to get better recognizing effect. One was turning the question of change parcel to the question of standard land type. Another was making strict regulation. This improved Distance Discriminate Analysis is not only visual and briefness, but also easy operational.

在设计变化地块识别的判决函数时，本文针对变化地块识别工作的特殊性：1、以无规律性、无集群性的变更地块为研究对象；2、以降低变更地块的漏判率为目标，对距离判别法做了如下改良：1、将无规律、无集群性的变更地块识别问题转化为有规律、有集群性的地类识别问题；2、严格判类规则(将落入误判高发区的待测样本视为变更地块)，以减少变更地块的漏判。

Seepage velocity smoothly change from a steady value to a new steady value, the ratio of the new steady value over the original steady value might increase hundreds of thousand times or even more, but it is always finite.（3）Water-inrush goes with the failure of rock strata, but seepage velocity can not increase unendingly, so seepage flow cant be unstable.

研究表明：由于非Darcy流β因子恒为正值，渗流系统总是稳定的；当渗透特性随时间变化时，渗流速度从一稳定值平滑地过渡到一新的稳定值，新的稳定值与原稳定值之比可以增大到几万至几百万倍，但是总是有限的；突水是岩层结构破裂引起的渗流速度快速或急剧变化，但渗流速度不可能无止境地增大，即渗流不可能失稳。

An uninflected item that has grammatical function but does not clearly belong to one of the major parts of speech, such as up in look up or to in English infinitives.

不变词：有语法功能但不明确地归于某个主要词类的无变化词，如 up 在 look up 中或 to 在英语不定式中

CTP is a fast, accurate and noninvasive method in evaluating the canine model of hyperacute ischemic cerebrovascular disease.

CTP检查可快速、准确、无创地评价犬急性局部脑梗死动物模型的脑血流动力学变化。

This action connoted by a liberal education lies wholly apart from what Newman claims is the danger of his own time: the enfeebling of the mind by a unmeaning profusion of subjects, as if we could be almost unconsciously enlightened by the mere multiplication of volumes.

这些被自由教育（不同于纽曼主张的自由教育）谎言指引的行为，是他生活中的一大危险：让一大堆无用的学科消磨着思想，就像我们可以几乎无意识地被细微变化启发。

The experimental apparatus has such functions as argon cleansing, heating outside the stove and closed loop control of temperature and pressure.

该实验装置具有氩气净化、炉外加热、温度和压力闭环控制，能同时施加正压、背压并按设定的恒压、恒极点胀形速度和应变速率进行实验，同时可以无接触地记录胀形件极点高度与时间的关系，并观察其形貌变化过程。

Early researches have been limited to animal experiment of detecting metabolism of brain. With the development of magnetic resonance spectrum, studying in vivo has come ture on the biochemistry metabolism's level, which makes a new breakthrough for us to continue research of IGE afterward.

以往的研究仅限于动物实验的方法检测其脑内的代谢变化，现在随着磁共振波谱(Magnetic Resonance Spectroscopy， MRS)的应用，无创地从生化代谢水平上研究活体已成为现实，为这一类疾病的研究打开了新的局面。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
