Suppose G is a finite group, then QG is a semisimple Q-algera, obviously ZG is a Z-order of QG,we denote the maximal Z-order by ?.If G is not abelian, it is not an easy thing to determine г; if G is an abelian group, then QG is isomorphic to the direct sum of a finite number of number fields, and r is the direct sum of these rings of algebraic integers of those number fields, but which elements of QG belong to r is not clear.

设G是一个有限群，那么QG是一个半单代数，ZG是QG的一个Z-序，设Γ是QG的一个极大Z-序，当G是一个非交换群时，Γ的求解是困难的问题；当G是一个交换群时，QG同构于有限多个数域的直和，Γ相应的就是各数域代数整数环的直和，但Γ具体是QG中那些元素不清楚。

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。

The activation energy of pyrolysis reaction decreases with the increase of catalyst polypropylene ratio from 0 to 30%.

当剂塑比从0增加到30％时，聚丙烯裂解的活化能呈现降低的趋势，特别当剂塑比为30％时，其活化能降低约50％。

I'll never stop I don't know, will you believe me After all is said and done All the lies, how I regret them baby Now, I am the loser And you're shining like the sun Tell me why can't I still be the one, alright I will never stop Until you're mine I can wait forever, till the end of time Cause my heart is in your hands Don't you understand I'll never stop I'll never stop How could I ever When my heart is in your hands And I know, baby there is no turning back They say that I'm crazy And I kind of understand How I wish for this nightmare to end Oh yes I will never stop Until you're mine I can wait forever, till the end of time Cause my heart is in your hands Don't you understand I'll never stop I'll never stop Ooh ooh, ooh ooh, ooh oohooh Do you believe me, when my heart is in your hands Don't you understand I'll never stop I will never stop Till the end of time Heart is in your hands I'll never stop Until you're mine I can wait forever, till the end of time Cause my heart is in your hands Don't you understand I'll never stop ..

我将从不停下来我不知道，你将相信我终归被说和做所有谎话，如何我惋惜他们婴儿现在，我是输者同时，你发光像太阳一样告诉我为什么我仍然不能是一，alright 我将从不停下来直到你是我的我永远能等待，直到时间的末端原因我的心在你的手中你不要理解我将从不停下来我将从不停下来如何能我曾经当我的心在你的手中时同时，我知道，婴儿没有往回旋转他们说我是疯狂的同时，我理解的种类我如何希望这恶梦结束啊是我将从不停下来直到你是我的我永远能等待，直到时间的末端原因我的心在你的手中你不要理解我将从不停下来我将从不停下来 Ooh ooh，ooh ooh，ooh oohooh 做当我的心在你的手中时，你相信我，你不要理解我将从不停下来我将从不停下来直到时间的末端我将从不停下来直到你是我的我永远能等待，直到时间的末端原因我的心在你的手中你不要理解我将从不停下来。。

When the cables use in alternating current system, rated voltage of cables should be at least equal the rated voltage of the system; When the cables use in direct current system,rated voltage should be not greater than 1.5 times of the rated voltage of the cables .

当他笔下的美女们做着种种骄羞的动作时，当她们盯着画者，其实也就是观众时，她们的眼神不仅有挑战，有向往，更有一种无法说清楚的暧昧与犹豫。

Species of a more northern zoogeography,notably the dominant amphipod Bathyporeia sarsi,showed a population collapse during warmer years and a subsequent reversal towards the cooler condition as temperatures decline.

较北部的动物种类，以优势种类片脚类动物Bathyporeia sarsi为代表，当温度升高时该种群面临崩溃；相反，当温度降低时种群恢复到以往水平。

3The values of AEMG of the contralateral multifidus were higher than ipsilateral during trunk axial rotation;(4) During the trunk flex to 45 and 65 degree position, the AEMG of lumbar multifidus and erector spinae muscles were higher than the other degree and there was significant difference.(Experiment 2)(1)The AEMG of the lumbar multifidus and erector spinae were influenced by load levels, load ways and road conditions during the walking.There was significant interaction between load levels and load ways.
