Aqueous extract of cotton has allelopathic effect on Raphanus sativus, Brassica campestris, Lactuca indica, Brassica campestris, Echinochloa crusgall, Setaria viridis and Abutilon theophrasti and its inhibition effect gradually strengthens with increasing concentration. Aqueous extracts from stems, leaves and roots of cotton inhibit or accelerate seed germination and seedling growth, and activity of enzyme of seedling root of cotton. While aqueous extracts from stems and leaves of cotton are 0.02 gmL^(-1), root length, shoot length, lateral root number and dry weight of cotton respectively increase by 10.3%, 3.1%, 22.9% and 2.4% over the control. The above mentioned indexes are lower than the control by 34.4%, 39.2%, 40.6% and 19.0% respectively as the aqueous extracts are 0.1 gmL^(-1). At the same time, root activity and SOD activity decrease by 38.2% and 36.7%, while POD activity and MDA content increase by 52.3% and 36.5%. Growth indexes of plant receptors increase at low concentrations but decrease at high concentrations of aqueous extracts. The allelopathic effect of aqueous extract of stems and leaves is stronger than that of root.

结果表明：棉花植株水浸提液对萝卜、白菜、莴苣、油菜、稗草、狗尾草、苘麻均具有化感效应，随着作用浓度增加，抑制效应逐渐加强；棉花茎叶和根系水浸提液对棉花种子萌发、幼苗生长、幼苗根系活力、根系酶活性有抑制或促进作用，当茎叶浸提液浓度为0.02 gmL^(-1)时，棉花根长、苗高、侧根数、干重分别比对照增加10.3%、3.1%、22.9%和2.4%，当浓度为0.1 gmL^(-1)时，上述指标与对照相比分别降低34.4%、39.2%、40.6%和19.0%，而根系活力、SOD活性比对照降低38.2%、36.7%，POD活性、MDA含量较对照增加52.3%和36.5%，不同浓度棉花植株水浸提液对棉花生长呈现"低促高抑"的规律，且茎叶浸提液作用效应大于根系浸提液。

Both the action pictures were shot using strobes so as to freeze the action and also give me a white and black background, and I just wanted to take a picture that had depth and you could look at for a little while letting your eye wonder, while being clean and relatively uncluttered as well.

在拍摄动作图片时，我一直都在用闪光灯，这让可以让动作凝固在画面中，而且可以制造出黑白分明的背景。而且我认为这样的图片拥有一种深度，同时画面又非常干净，可以让你的视线长久地停留下来，促使你去思考。

But it could be that the biggest difference between perceptions of the two players', the biggest reason why MJ will be remembered so adoringly, while Kobe could be remembered by some as much with vitriol as love, is because Kobe played in a time when everybody in the world had access to every aspect of his career, positive and negative, while Jordan played in a time when the general NBA fan only heard about his greatness.

但是外界对于这两人的看法也许就是他们最大的不同之处了，乔丹会被受崇拜地记得，而科比则会流连于爱与恨之间，这是因为科比处于一个所有人都可以关注到他生涯每一个细节的世界，无论是正面的还是负面的，而乔丹所处的时代大体上的 NBA 球迷只能听到乔丹的伟大。

The amount of ammonfying took absolute dominance while that of cellulolytic was the lowest. Aerobe azotobacter played an important role in fixing nitrogen while aerobe bacteria was vital in fibrin-dissolving.

氨化细菌总数处于绝对的优势，纤维素分解菌的数量最少，好气固氮菌在固氮活动中起主要作用，纤维素的分解主要是好气性菌在起作用。

In order to implement simultaneous casing while drilling of larger diameter pile holes and water wells in complex strata, a new type of bit for simultaneous casing while reverse circulation drilling with DTH air hammer was developed.

为实现在复杂地层用同步跟管钻进工艺钻凿直径较大的桩孔和水井，设计了一种气动潜孔锤反循环跟管钻进钻头。

Results: The refraction results of the Allegretto Wave Analyzer were very unstable. The spherical, cylinder diopter and the axis of the cylinder varied greatly. The refractive errors were large while the refractive errors were little by the subjective refraction examinations. During the wavefront examination, spots of the laser matrix were blurring, and the reproducibility was not good. Wavefront analyses showed that the Array pseudophakic eyes had relative large coma while the patients had no obvious symptoms.

研究结果：像差分析仪检测得的屈光度结果十分不稳定，球镜度、柱镜度、散光轴都变化很大，可重复性差，检测的屈光不正度数较大，而主觉验光时，患眼的屈光不正度数较低。5只眼的光学矩阵的测量点均非常模糊，且测量结果的可重复性较差，像差分析显示，Array人工晶状体有很大的第三阶彗差，但患者的自我感觉良好。

Livestock wastewater contains not only high concentration of organics, but also amino acid. This paper studied efficiency of UASB applied in such wastewater, and the influences of environmental and operation conditions on ammoification rate were analyzed. Results show that suitable pH for the bacterium had a wide range from 6. 5 to 8, and pH 7 was the best. A positive correlation was between temperature and ammonification rate, while 38℃ was prefered from an economic point of view. Ammonification rate increased with the influent concentration of increase while there's a contrary situation when the organic load increase.

因畜禽废水除了含有大量的有机物，还含有一定量的氨基酸，因此，研究利用UASB处理畜禽废水，在不同环境条件和工况条件下对氨化率的影响，结果表明：氨化菌适应的pH值范围较宽，在6.5~8.0范围均可以较好的生存，其中以7.0为最佳；温度与氨化率基本成正相关关系，从经济等多种角度考虑，中温阶段38℃为最适宜；氨化率随进水浓度的增加而增加；进水有机负荷越大，氨化率越小。
