To find evidence of neutrinos, physicists must wait for the particles to knock into other matter.

为了发现中微子存在证据，物理学家必须等待这种粒子与其它物质发生碰撞。

Neutrinos are elusive particles that rarely interact with other matter, and are normally only glimpsed in huge detectors.

中微子是一种很难捉摸的粒子，因为它极少与其他物质发生相互作用，通常只能在非常巨大的探测器里才能瞥见。

One group was fed a regular diet and received standard care; a second group received standard care but was fed an antioxidant fortified diet,consisting pf standard dog food supplement with tomatoes,carrot granules,citrus pulp,spinach flakes,the equivalent of 800 IUsof vitamin E 20milligrams per kilogram of vitamin c ,the third was fed a regular diet ,but their environment was (regular exercise,socialization with other dogs ,and an acces to novel toys),the forth group received a combination of the antioxidant diet as well as environmental enrichment.

一个小组被哺养了规则饮食和接受了标准关心；第二个小组接受了标准关心但被哺养了抗氧剂筑堡垒于的饮食，包括的pf 标准狗食补充用蕃茄，红萝卜粒子，柑橘黏浆状物质，菠菜剥落， 800 IUsof 维生素E 等值20milligrams 每公斤维生素C，三被哺养了规则饮食，但他们的环境是(规则锻炼，社会化与其它狗，和acces 对新奇的toys)，小组以及环境充实接受了抗氧化饮食的组合。

The influence of the temperature to the equation of state of npe neutron matter is not obvious, and the influences to the composition of various particles are mainly in the range of small baryon density.

对npe系统中子星物质的研究表明温度对该类中子星的物态方程影响不大，对粒子所占比例的影响主要表现在低重子密度区域。

The study of the morphology of PPy/nanoparticle composite material by scanning and transmission electron microscopies shows us that the gold nanoparticles can be stably coated on the surface of PPy. The Surface-enhanced Raman Scattering spectrum results indicated that the composite microtubes can be applied to hold and analyze trace molecules as signal-enhancing cuvettes for Raman spectroscopy.

扫描电子显微镜、透射电镜观测结果表明：金纳米粒子能够稳定地包覆在聚吡咯管壁上；表面增强拉曼光谱研究表明：该复合材料具有良好的表面增强拉曼信号功能，与复合前相比，拉曼信号增强104~105，可望用于痕量物质的检测。

In the material world this is quite exceptional because magnetic particles are usually observed as dipoles, north and south combined.

在物质世界这是非常独特的，因为磁性粒子通常观察到的是南极和北极，并且都是结合在一起的，然而有几个理论预言了磁单级子的存在。

The various effective interactions'(including DDME1,TW99,NL2,TM1,TM2,GL85 and GL97) influence on the constitute, equation of state and mass of neutron star are studied in the framework of relativistic mean field theory considering the interacting nucleons, hyperons and mesons system at finite temperature (T=20 MeV).

从相对论平均场（Relativistic Mean Field，RMF）理论出发，考虑核子、超子和介子的相互作用，研究了一定温度（T=20 MeV）下，各种不同相互作用参数组（DDME1、TW99、NL2、TM1、TM2、GL85和GL97）对中子星物质的粒子组成、状态方程和质量等的影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
