Suitable substrates were the key factors for xylanases production. XylanaseB was produced mainly when corn starch or beechwood xylan was used as the inducing substrate.

发酵底物是产生木聚糖酶的重要影响因素，在以玉米淀粉或山毛榉木聚糖为底物时，产生的木聚糖酶主要是木聚糖酶B，而以廉价的麦麸为底物则主要产生木聚糖酶G和B。

It can be concluded from the above analysis that at the beginning of language, simple linguistic signs, coming from sound imitation, natural exclamation and morphological stimulation, took a strong feature of iconicity, while arbitrariness still existed to a little extent. With time going by, the primitives had to create more linguistic signs to meet their needs of survival and development, so that they arbitrarily related the sound patterns and concepts to conventionalize them as linguistic signs adopted in the whole society. During this period of time, arbitrariness played a more important role, while iconicity still worked as phenomena of phonaesthesia designate. With society developing, human beings found that it was not enough to create new signs at will, so they began to make use of some principles like compound, derivation, etc. to form new linguistic signs, either simple or complex. The linguistic signs formed during this period of time always took a better disguise to be iconic, while no one until now could defuse the contributions of arbitrariness of their formation. From the above investigations, it can be seen that arbitrariness and iconicity interact in the whole process of language development at the level of lexicon. If there were no arbitrariness, human language could not expand at the very beginning.

因此可做如下推论：在语言产生之初，简单语言符号的产生常常都是有理据的、象似的，但是仍不排除任意性的作用；后来有理据的词无法满足人们生存和发展的要求，人们开始任意地连接声音形象和概念，并约定俗成获得语言符号，此时任意性起主导作用，但是象似性在音义关系中对语言符号的产生起着不可否认的作用；随着社会的发展，人们发现这些词已经不再能满足需要，而创造更多的词也不是很可能，所以人们开始采用一些构词法来创造新的语言符号，此时产生的语言符号往往更具象似性，但其核心仍然是任意的。

Result The three strains all produced the AHL signal molecules; the strains FML05-land FML05-2 produced two types of AHLs at least and the N-3-oxo-octanoyl-homoserine lactone was the predominant signal molecules. The production of siderophore and proteinase in FML05-2 were reduced by co-incubation with AHL degrader strain.

结果］3株菌均产生AHLs信号分子；菌株FML05-1、FML05-2至少产生两种AHLs分子，二者所产生的主要信号分子是N-3-氧代－辛酰基－高丝氨酸内酯(N-3-oxo-C8-HSL)；FML05-2与降解AHLs的菌株共同培养，发现嗜铁素的产量与蛋白酶活性明显下降。

Several inducers cicada exuviae, colloidal chitin, horsefly cuticle, shrimp, maggot and silkworm chrysalis were compared with their effects on production of cuticle-degrading protease of entomopathogenic fungus Metarhizium anisopliae.

研究了不同碳氮源对金龟子绿僵菌产生与分解昆虫外壳相关的蛋白酶活性和同工酶谱带的影响。结果表明：蝉蜕、虻虫壳、蝇蛆壳、蚕蛹壳、虾壳、胶体几丁质均可使金龟子绿僵菌产生蛋白酶，虾壳和胶体几丁质所产生的蛋白酶比活性最高，蝉蜕次之。

When meteorite hit the Earth surface, it created shockwave to transfer the kinetic energy to the Earth surface. When the speed of meteorite strike reached 10 km/second, the pressure of shockwave can reach several millions bar to compress the target terrane to produce heat, the effect of impact deformation caused by it is several scales stronger than rock intensity, the granite would melt down once the pressure of shockwave reached about 500 thousands bar, the granite would gasify (solid became liquid and meanwhile further became gaseity) once reaching over 600 thousand bar.

当陨石撞击地表时产生冲击波把陨石的动能传给地表，在陨击速度达到10公里/秒时冲击波的压力可达到数百万巴并压缩靶点岩层物质产生热，它产生的冲击变形效应比岩石强度大几个量级，冲击波压力约50万巴时花岗岩就熔化，大于60万巴时花岗岩就气化（在固态转为液态同时进一步转为气态）。

In combination with sensitivity analysis, it is found that the main reason causing the fuse failure in bore is the lateral shock between the bourrelet and the bore surface. This shock produce huge lateral impulsive force and acceleration causing fuse mechanism plastic deformation and improper function. Besides, it may lead to fall-off in fuse safety.

造成引信瞎火的主要原因是由于弹丸在膛内运动期间，弹丸与身管内壁间的相互碰撞所产生的横向冲击加速度使引信保险机构产生多次重复振荡，使其产生局部塑性变形及破坏不能可靠解除保险所致；并可能导致引信膛内安全性下降。

Viruses will cause much confusion. Even some virus "experts" will misinform the cause of the virus.

病毒是导致很多问题产生的一个原因，甚至有些专家也会对病毒的产生产生误解。

In order to ensure the safety of pump house, it is necessary to avoid producing sparks, which are mainly resulted from leakage of electric equipment and electrostatics of human body and pipeline.

为了保障油泵房的安全，必须避免产生火花等点火源。油泵房中产生火花主要是由于电气设备漏电、输油设施和人体带电产生的。

The producing time of sexuparae aphids by the cotton specialized aphids was earlier than that by the cucumber specialized aphids, whereas the apterous aphids produced by cucumber specialized aphids were significantly more than those by cotton specialized aphids.

结果表明：两寄主专化型棉蚜在产生有性世代能力上存在显著差异，表现为棉花型棉蚜在诱导后代中产生有翅蚜、雄性母和雌性母的比率显著高于瓜型棉蚜，并且雌、雄性母产生的时间明显早于瓜型棉蚜。

It is mainly formed by the reaction between urea (produced by the breakdown of arginine by the yeast) and citrulline (produced by the degradation of arginine by malolactic bacteria and ethanol).
