辐射体

Sometimes armed with stinging hairs; epidermal cells of leaves, sometimes stems, perianths mostly with prominent cystoliths punctiform to linear; Leaves alternate or opposite, stipules present, rarely absent; leaf blade simple. Inflorescences cymose, paniculate, racemose, spicate, or cluster-capitate, usually formed from glomerules, sometimes crowded on common enlarged cuplike or discoid receptacle, rarely reduced into a single flower. Flowers unisexual, rarely bisexual in partial flowers; actinomorphic, very small,(1-)4- or 5-merous, rarely perianth absent in female flowers.

有时具有蛰毛的刺；叶的表皮细胞，有时茎和花被的表皮细胞大部分有显著的点状或线形的乳状体；叶互生或者对生，托叶有，很少无；单叶花序聚伞状，圆锥状，总状，穗状，或者丛生头状花序，花单性，部分花两性；辐射对称，小，(1-)4-或者5瓣，很少在雌花内无花被。

Soybean hypocotyls were treated with doses of UV-B at 8.22 kJ/m~(2d and 12.42 kJ/m~(2d UV-B radiation, corresponding to depletions in the stratospheric ozone of about 12 % and 20%, respectively, for a clear solstice day at Lanzhou city (36.04°N, 1550m),China.

报道表明增强 UV - B辐射会引起细胞 DNA形成嘧啶二聚体 [2 ] ，影响细胞正常代谢和分裂 [3] ，导致黄瓜子叶 [4 ] ，欧芹叶片 [5] ，小麦叶片 [6 ] 细胞分裂速度减慢。

The electrolyte leakage from the duckweeds cell increased by enhanced UV-B radiation with the increasing time of treatment. Perhaps lipid peroxidation is one of the causes of membrane damage, and reactive oxygen species were involved in the process.

电镜观察发现，经过UV-B辐射处理20天，紫萍叶状体叶肉细胞的膜结构受到破坏，可能膜脂过氧化和活性氧自由基起了重要作用。

The heat receiver cavity radiation mathematical model and the gas tube heat model were established.

建立了太阳能热动力发电系统吸热器腔体辐射模型，结合换热管的传热模型计算了吸热器的传热过程。

The affects of crystal absorption for heat radiation on crystal growth,which include:the heat loss of the hot grower,the chara cteristic of temperature time of crystal growth,the pattern of fluid flow and the shape of interface,the interface inversion of crystal,the temperature distribution and the thermal stress distribution,are reviewed in this paper.

本文综述了晶体对熔体热辐射吸收对晶体生长的影响，包括对热腔热耗散的影响；对晶体生长温度时间特性的影响；对液流形态和固液界面形状的影响；对晶体界面反转的影响；对晶体中温度分布和应力分布的影响。

But before she could get there, the crowd dispersed before a couple of policemen, who had appeared among them brandishing their truncheons

可是还没到，那一堆人霍地分开，露出两个巡捕，拿起棍子，正在找人发威。热体的辐射可以用分光仪使之产生色散而形成光谱。

High transverse momentum partons which come from hard scattering will propagate in the strong interaction medium and interact with matter. These partons are expected to lose their energy in the medium by gluon bremsstrahlung, which is called Jet Quenching.In BNL/RHIC Runl (S_~(1/2)= 130GeV and Run2 (S_(NN~(1/2)= 200GeV, comparing the yield of leading particle in nucleus-nucleus collisions with nucleon-nucleon collision finds that charged and neutral pions are suppressed.

在相对论重离子碰撞中，末态高横动量强子产额的压低被认为是夸克胶子等粒子体已经生成的一个重要信号，在高能核-核碰撞过程中，硬散射发生在碰撞过程的初期，由硬散射过程形成的大横动量部分子将穿越强相互作用物质，这些硬部分子与热密物质发生强相互作用，经过韧致辐射而损失能量，我们把这种现象称为喷注淬火。

The theoretical formulas about the radiation sound pressure of a complex cavity under an external force are deduced in detail.

首次提出了一种新的声固耦合分析方法——覆盖域法，详细推导了用该方法求解复杂腔体在外力作用下的辐射声场的理论计算公式，并通过实验验证了覆盖域方法的正确性。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
