物质

It concentrates the wort, nearly sterilizes it, inactivates enzymes, precipitates remaining proteins that would otherwise contribute to beer turbidity, caramelizes sugars slightly, and extracts the flavor and tanninlike substances from the hops.

它浓缩了麦芽汁，近乎对麦芽汁灭菌，使酶失活，使能够引起啤酒混浊的残存蛋白质沉淀，使糖轻微焦化，并从酒花中提取风味物质和单宁物质。

The sac structure projected through the pollen aperture possesses the typical nature of transfer cell, i. e complex lybrinthian wall ingrowth and abundant mitochondria, RER, dicotysomes and ribosomes under the wall. Its outer surface is closely related to the tapetal protoplast. The accumulation of storaged material in pollen start at the area near the apertures. Above restults indicate the pollen apertures may be the"door"from where nutrition flows into pollen in P. hortorum.

绒毡层物质向花粉粒的短途运输明显的表现在花粉的萌发孔区，一方面形成向外突起的囊腔，另一方面在这里具有发达的壁迷宫，而且迷宫下具丰富的线粒体，RER和高尔基体等细胞器，此外花粉内贮藏物的大量积累首先从萌发孔附近开始以及萌发孔处与绒毡层有紧密接触都说明天竺葵花粉萌发孔可能是物质进入花粉的&门户&。

The aim was to discuss the effects of plant growing regulators on the rooting of shoots of Trachelospermum jasminoides by soft-cuttings, so as to provide basic data for the species introduction and breeding of Trachelospermum jasminoides as well as the practical technique improvement of plant growth regulators.

［目的］探讨植物生长调节物质对络石嫩枝扦插生根的影响，为络石引种扩繁、完善植物生长调节物质使用技术提供基础数据。

The success was mainly due to the dilution of sea water to certain extent ( 25-50%) so that the Tradescantia inflorescences could remain alive during the time pe-riod required in the experiment.

我们发现紫露草能于海水中在实验要求的时间内成活，并通过实验证实了微核产生的原因不是海水本身，而是海水中的污染物质，污染物质含量越高，产生微核的频率也越高。

The theory implies that the body is capable, through energy exchange, to short-circuit the system by ingesting its own secreted body fluids to stimulate the transmutational forces within and challenge the body to transform unusable substances into usable ones.

这理论意味着，身体有能力，通过能量交换，通过喝他自己分泌的体液去短路系统去刺激转变内力和激发身体去转变不能使用的物质为能用物质。

Any chlorine residues in the water may react with organic compounds to form harmful by-products such as trichloromethane that are difficult to remove and are known to be cancerous.

再者，水中的有机物质与氯产生化学反应后会形成有害化合物，如三卤甲烷，这些难以清除的化合物更被确定为致癌物质。

Optimization of liquid culture medium including maltose, glucose and tryptone for nucleotides production with Cordvceps sinensis CS-wx was carried out by response surface method.

采用响应面法对冬虫夏草茵CS-wx液态发酵生产核苷类物质的3种主要培养基成分——麦芽糖、葡萄糖和蛋白胨进行优化，采用多元二次回归方程拟合3种因素与核苷类物质含量为响应值之间的函数关系。

Therefore, the growth substances investigated played different roles during tuberization, which were the bases of growth and development of potato plantlets.

块茎形成与单个物质的绝对含量并不存在直接关系，但单个物质在块茎形成过程中发挥着的作用是不容忽视的。

The results showed that the higher levels of plant growth substances, namely hearty physiological metabolism were necessary for tuberization, but there was no direct relationship between one substance only and tuberization.

块茎形成需要这些物质的大量积累即体内旺盛的生理代谢，特别是前期较高水平的生长物质是植株生长发育及块茎形成良好的基础。

Hot on the heels of evidence last year that dark matter really does exist (see 'Dark matter spied in galactic collision'), the same technique has been used to map this uncharacterized mass across half a million distant galaxies.

紧追着去年暗物质确实存在的脚步，同样的技术被用来绘制50万光年远的星系中的这种毫无特征的物质。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
