Regular porosity in about 38 nanometer size was observed using atomic force microscopy. Excitation and Emission spectrum were obtained by using F-4500 fluorometer.

用F-4500型荧光分光光度计测量其三维荧光谱，与未经氧化的铝片作对比，发现前者的激发谱在280 nm~340 nm有一个较宽的谱带，并且在253.8 nm附近有一个肩峰，发射谱有一个以417.4 nm为峰值的较宽谱带，而后者却无任何明显的发射峰和激发峰。

The labial frenum is a fold of mucous membrane which contains no muscle and has no action of its own. Its attachment on the labial side of the ridge is often low, depending on the degree of resorption of the ridge. The labial flange of the denture must possess a corresponding notch to allow the frenum to pass through.

The study indicated that RAPD technique is useful and practical for the identification between gynogenesis fish and hybrid individuals.RAPD and AFLP technique were used to screen the sex-related DNA marker through analyzing the DNA differences between female and male of Jian carp.

通过对反应条件的优化处理，在引物E-ACG／M-CAA的扩增图谱中找到一条雌性特异的DNA条带，分子量约323bp，雄性个体均无此条带，初步发现了雌雄之间的遗传差异，可为建鲤遗传性别的鉴定提供参考；同时发现某些位点在雌性和雄性个体出现的比例存在很大差异，推测与遗传性别有一定的关联。

I inquired that said these cultivations the seafood is mainly is iced up the influence, the supply is not big, but inshore fishing's silver pomfret fish is out of stock very much, the distant seas fishing for hairtail goods supply quantity is not big, by the small market saw frequently to eight belts, the goby and so on fresh small seafood, is only in the individual stall has the sale to freeze the small seafood, formerly could wholesale the solid stuff, did not have the trail now.

蛤蜊从每斤5元涨到8元，扇贝涨到了15元两斤，海蛎子、八带、虾虎等小海鲜的价格也出现了小涨，我打听说这些养殖的海鲜主要是受结冰影响，供应量不大，而近海捕捞的鲳鱼很缺货，远海捕捞的带鱼供货量也不大，以小市场经常看到八带、虾虎等新鲜小海鲜，只是个别摊位上有销售冰冻小海鲜的，以往能批发的干货，现在无踪迹了。

Rumjantsev used Hamilton's principle with Lagrange's multipliers to generate the dynamical equations of a rigid-fluid coupled system in 1954 and the dynamical equations and their dynamical boundary conditions of a fluid-elastic coupled system in 1969, where the fluid is incompressible and inviscid. In 1990, Liu used Jourdain's principle with Lagrange's multipliers to generate the dynamical equations of a rigidfluid coupled system, where the fluid is incompressible and viscid.

Rumjantsev利用带Lagrange乘子Hamilton变分原理于1954年建立了刚—流耦合系统的动力方程，于1969年建立了流—弹耦合系统的动力方程及其动力边界条件，其中所考虑的流体是不可压无粘液体；Liu利用带Lagrange乘子Jourdain变分原理于1990年建立了刚—流耦合系统的动力方程，其中所考虑的流体是不可压粘性液体。

By analyzing the mechanics relation between the sprocket wheel and the pallets of the pallet draught device in a sintering machine,the non- arching mechanics model of the pallets was established and the force control method for the non- arching sintering machine was put forward.

通过分析带式烧结机台车执行牵引装置的星轮和台车的力学关系，建立了台车无叠肩起拱的力学模型，提出了无叠肩起拱带式烧结机的力控制方法。

First the passivity of motor rotor flux subsystem is proved. Workless forces have no influence on the energy balance equation and have no effect on the asymptotic stability. Then it is discussed that the system can stably track the reference rotor flux without rotor flux observer. At last an adaptive PBC strategy is proposed with regard to the rotor resistance change. A clear and simple design for the speed control subsystem with inner current loops is presented.

证明了感应电机转子磁链子系统的无源性，找到系统能量耗散特性方程中的无功力，它不会影响系统的稳定性，得出无需转子磁链观测反馈即能稳定跟踪转子磁链的参考值，同时考虑电机转子电阻在运行中发生未知变化，设计自适应调节器使系统对转子电阻呈现鲁棒性，构建了带电流内环速度控制系统。

In the preparation of the material, VitC was added, and the protective effect of antioxydant was tested by investigating the changes of the crystallin during the cataractogenesis which included the content, component of polypeptide and the conformation of the secondary structure of the protein.

结果在VitC的保护作用下晶状体蛋白的低分子量蛋白的含量明显增加，PAGE电泳中出现多条分子量较低的蛋白条带，但SDS-PAGE的泳带无明显改变，CD谱显示α-螺旋增加和β-折叠减少。

Causes the ordinary belt conveyer through the increase corner station to realize the great angle plane turning movement to have the vital significance, it not only has developed the ordinary belt conveyer application domain, may realize does not have the power continuously to reprint the transportation, enhances the use factor of the equipment, moreover the simplification of transportation system, reduces the equipment failure rate, enhances the reliability and the operation efficiency, also is the harbor, the station, the mine and so on other place great angle curve continuous haulages effective ways.

通过增加转角站使普通带式输送机实现大角度平面转弯运行具有重要的意义，它不仅拓展了普通带式输送机的应用领域，可以实现无动力连续转载运输，提高设备的利用率，而且简化运输系统，减少设备故障率，提高可靠性和运营经济性，也是港口、车站、矿场等其他场所大角度转弯连续运输的有效方式。

First use soap-free emulsion preparation for polystyrene spheres, and the kernel, Reuse are silicon acetic tetraethyl ortho-silicate in ammonia catalytic hydrolysis, formed under the condition of silica, charged by six water or their cerium, six of methylene amine solution HMT (4) into the negatively charged, uniform cerium oxide coated surfaces to PS microspheres, core-shell structure of PS - CeO2 and PS - SiO2 composite microspheres.
