复杂群

Although MSG is considered a safe food additive for most of the population, there are a group of people with severe, poorly controlled asthma who are prone to MSG symptom complex and may suffer temporary worsening of asthmatic symptoms after consuming MSG.

虽然MSG对多数人认为是安全的食品添加剂，但有一群人有严重很难控制的哮喘，有使MSG症状复杂的倾向和可以在使用MSG之后关节炎症状暂时变坏。

Of them, we proposed the term of the Toyon volcanogroup in the first time. All the volcanoes can be subdivided into two types: central-eruption-typeand flood-basalt-type, building a series of volcanic mechanism, including calderas, volcanicnecks and cone sheets.

托云火山岩是由多个近于同时喷发的火山口的喷出物复杂堆积的产物，这些火山口可以划分成中心式火山和溢流玄武岩两种类型，它们共同组成了托云火山群。

The results indicated that there were two-phase and three-phase regions only,was not any trinal intermediate phase in the investigated Si content range.Two binary pseudo-alloys took place solid-phase changes at 556℃ and 471℃ respectively.

结果表明：在研究的Si含量范围内，相组成较复杂，但仅有二相区和三相区，未发现三元中间相。2个伪二元合金系在556℃和471℃存在固相转变，且Cu3Si相的η、η′和η"相同属正交晶系，其相变属于"位移型相变，空间群有待进一步研究。

A new fuzzy control strategy was presented for the temperature in the tunnel kiln based on adaptive particle swarm optimization algorithms.

针对隧道窑燃烧过程中的大惯性、纯滞后、多变量、时变参数以及工作机理复杂等特征，利用清晰集构造模糊集法确定模糊控制器输入量和输出量的隶属函数，并基于自适应粒子群算法给出了隧道窑新的温度模糊控制策略。

For complex multi-peaks function with high dimensions, the classical PSOA has some serious disadvantages such as slow convergence and weak ability of local search.

在求解高维空间中复杂多峰函数的优化问题时，传统的粒子群算法在收敛速度和局部搜索能力等方面表现出严重不足。

For example, in a study published last year in the Proceedings of the National Academy of Sciences a group of researchers looked at crustaceans (crabs, shrimps, woodlice and so on) over the past 550m years and found far more examples of groups of species evolving towards complexity than in the other direction.

举个例子，去年美国国家科学院公布的一项研究里，一群研究人员对生活在过去5.5亿年里的诸如螃蟹、虾、节肢动物有树虱之类的甲壳纲动物进行了研究。他们发现，更多的物种群体是朝着复杂而不是别的方向进化的。

Been long-term protected by local people, a stable heron community has been formed at Wanheshan either, it includes 10 species of Ardeidae, among them 7 species nested together to form a large "heron woods", it is of high value in scientific research.

因此，该保护区在生物多样性保护中具有重要作用。亦是经过当地群众长期自发保护，在防城区万鹤山亦形成了一个稳定的鹭鸟群落，保护区内现有鹭科鸟类10种，其中7种鹭鸟聚集在万鹤山小范围内营群巢，成为大型复杂的鹭林，具有极高的科学研究价值。

The results showed:(1)The flora of community is rich and complex,and it belongs to the transitional zone for many genera,the subtropical-temperate zone geographical composition of genera are dominant,about 51.47% of the total genera,and there are characteristics which form subtropical to temperate zone transition.(2)The species are mostly composed of Fagaceae,Lauraceae,Anacardiacea...

结果表明(1)该群落区系组成比较丰富和复杂，属于许多属的过渡地带，具有从亚热带向温带过渡的特征；(2)种类组成以壳斗科、樟科、漆树科、卫矛科、榆科、五加科、金缕梅科等为主，但优势种、建群种以温带属为主；(3)种群生活型谱以高位芽占绝对优势，群落垂直结构明显。

A very complicated mantle mineral group including the native iron and wustite assemblage was recently discovered in chromitites from the mantle harzburgite of Luobusa ophiolite, Tibet.

笔者在西藏蛇绿岩的铬铁矿石中发现了十分复杂的地幔矿物群，其中包括自然铁-方铁矿的共生组合，它们被认为是外地核和下地幔的物质通过地幔柱作用携带到上地幔的。

Maize germplasm gets more and more mixed. To make full use of heterosis, it is very important for maize breeders to distinguish heterotic groups and to design heterotic patterns.

玉米种质日趋复杂，对现有种质资源进行杂种优势群的划分，构建杂种优势模式的基本框架，将对进一步提高杂种优势利用水平，对当前和今后的玉米育种工作有重要的指导意义。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
