One of the significant advantages of soilless culture is that the root environment is easy to be controlled.

无土栽培的显著优越性之一就表现在植物的根际环境要比土壤的易于控制。

Since then, several scientists during the late 1920s and early 1930s, including those well known by their analytical methods such as Bray, Morgan, Spurway, and Truog, advanced soil test- ing by showing the importance of measuring labile or available rather than total plant nutrient contents.

从那时起，在几位科学家后期 20世纪20年代和30年代初，包括那些众所周知的分析如布雷，摩根，Spurway方法和化学家曲劳，先进的土壤测试荷兰国际集团通过显示测量的重要性，而不稳定或可用比总植物养分含量。

In the blink of an eye you are surrounded by a pale,stickly web with fine strands as strong as any rope.

那双明亮的眼睛看到的是，你被一张白色有黏性的网粘着，这网比任何一根绳子都牢固。

Such plants usually have one or more domatia, cavities in stems, leaves or roods that house ants. These may be elaborate systems of cavities with many chambers, e.g. Myrmecodia, or simple hollows in internodes, leaf veins, petioles or stipular spines, e.g. whistling thorns.

这类植物通常都具有一个或多个虫菌穴，虫菌穴是在植株的根、茎、叶上用来容纳蚂蚁的空腔，这些空腔具有许多发达的小室，例如茜草科具有简单而中空的结间部，阿拉比卡咖啡具有含有空腔的叶脉，有的植物叶柄及托叶处也有这样的结构，例如牛角刺槐。

Rhizomes erect or ascending; insertion of calyx on receptacle ± tetragonous; filaments of inner stamens wider than anthers

A new colorimetric chemosensor 1 based on a tripodal benzaldehydic-phenylhydrazone selectively sensing acetate ion has been synthesized.

本文合成了一个新的基于三脚架苯甲醛苯腙的能够选择地检测醋酸根离子的比色化学传感器1。

Results. Cement augmentation of pedicle screws resulted in significantly higher failure loads (54%) and failure strength (69%) for both shaped indentors when compared with uncemented pedicle screws.

结果：经骨水泥增强的椎弓根螺钉组比无骨水泥组在负荷失败率和强度失败率方面两种形状的压配中均有显著差异。

Result After soaking seeds with 10, 20, 30, 40 mg/L of triadimefon, the plant height of V. unguiculata seedlings was obviously restrained, the ration of root to shoot was significantly increased and the root length was decreased to different extent.

结果］10、20、30、40 mg/L三唑酮浸种后，豇豆幼苗的株高受到明显抑制，根冠比显著增加，根长有不同程度的降低。

Objective:The koji, production process and product index of North of Hunan unhusked rice wine and Middle Hunan rice wine were studied to give evidence for industrial production of unhusked rice wine; Methods: Glucoamylase activity, alcoholic fermentation activity, alcoholicity, all ester and the number of microbe were examined with ordinary ways; Results:The number of microbe and Rhiz.

目的：对湘北谷酒与湘中米酒酒曲、生产工艺以及成品酒指标进行比较，为谷酒的产业化生产提供依据；方法：采用常规方法测定、比较糖化力、酒化力、酒精度、总酯、微生物含量；结果：谷酒酒曲的微生物总数、根霉菌数糖化力与湘中米酒酒曲基本相同，但酵母数、酒化力略高于米酒酒曲；湘北谷酒的酒度、出酒率和总酯均高于湘中米酒，高级醇含量基本持平，感官指标优于湘中米酒；结论：谷酒较米酒的发酵工艺更合理，蒸馏方式更科学，产品质量更稳定；谷酒比米酒更适合大规模产业化。

The morphology of the mineral dependents on the solution characteristics. The main component of mineral was hydroxyapatite containing a little of CO32- group which the Ca/P ratio is 1.53, similar to the major mineral component of bone tissue. The porosities of the mineralized and unmineralized 3-D porous PLGA were (84.86±8.52)% and(79.70±7.70)% respectively. The biomechanical strength was 0.784±0.156 N/mm2 in unmineralized PLGA and 0.858±0.145N/mm2 in mineralized PLGA.

结果：PLGA经碱性溶液水解处理后表面亲水性明显增强，在0.5倍SBF中仅有少量矿物沉积，在SBF及1.5倍SBF中矿化后表面可以形成明显的矿化物；矿化物的形态与矿化液的浓度有关；矿化物主要成分为羟基磷灰石，含有碳酸根成分，钙磷比为1.53，类似于人骨无机质。
