海绵质的

Culms 2–5 m, 5–12 mm in diam.; internodes terete, 20–32 cm, pith spongy; nodes weakly prominent, sheath base persistent, corky, glaucous, pilose; intranode ca. 9 mm. Culm sheaths persistent or late deciduous, brown, shorter than internodes, fragile, densely setose; auricles falcate; oral setae ca. 5 mm; ligule arcuate, ca. 2 mm; blade triangularly ovate-lanceolate, abaxially slightly hairy at base.

秆2-5米，5-12毫米直径；节间圆柱状，20-32厘米，木髓海绵状；节身体虚弱突出，宿存的鞘基部，木栓质，有白霜，； intranode约晚落叶的9毫米竿箨宿存或，棕色，节间，脆的短于，密被刚毛；叶耳镰刀形；口头的刚毛约5毫米；弧曲的叶舌，约2毫米；叶片三角形卵状披针形，背面的稍有毛在基部。

This paper determined the olfactory respones of Tetranychus viennensis to different plants odors with "Y" olfactometer and petri-dish, volatiles from leaves of different plants were absorbed with SPME and analyzed with GC-MS (gas chromatograph-mass spectrometer). At the same time, the effects of different host plants on the development of Tetranychus viennensis were determined by means of the leaf-dish rearing method , in addition, the contents of some chemicals in the leaves of different plants were also determined.

本文用&Y&形嗅觉仪法和培养皿法测试了山楂叶螨Tetranychus viennenis Zacher对不同植物气味物质的嗅觉反应，并利用固相微萃取SPME吸附、用气相色谱—质谱联用仪GC-MS(gas chromatograph-mass spectrometer)分析了不同植物叶片的挥发性物质成分：同时采用海绵水盘法饲养山楂叶螨，研究了不同植物对山楂叶螨生长发育的影响，并测定了不同植物叶片中一些生化物质的相对含量。

Through studying the structure, the characteristic, the growth mechanism and mediation in sponge spicules, scientists are learning a new biotechnological route to produce electronic and optical nanomaterials in an environmentally benign way.

近年来，人们发现了硅质海绵骨针独特的微结构及良好的光纤特性，特别是指出了这些特性给人类带来制造光纤的新思路，并很快引起了科学家对其结构、特性、生长机制与调控的生物学、生矿物学和仿生学的广泛研究兴趣。

The re-enforcement fiber CPPf in the scaffold composites could significantly increase the density, porosity and elevate the compressive strength and rigidity in a content-depended manner, compared with simple scaffold PLLA prepared with same method. What's more, the inner microstructure could convert from microporous sponge structure of low porosity to fibrous network of high porosity.

PLLA支架材料中复合CPPf能够明显增加或增强相同方法制备的单纯PLLA支架材料的密度、孔隙度及压缩强度和刚度，而且随着支架材料骨架基质中所含CPPf重量比的增加，其作用更加显著，其内部微结构由较低孔隙度的微孔海绵状结构过渡为高孔隙度的纤维网状结构。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
