束状

Taproots stout, branched near stem into a cluster of several long, woody, carrot-like roots with prominent annular scars when old.

坚固的直根，接近茎的分枝形成一束数个长的，木质的，胡萝卜状的根，在老时具突出的环状的痕。

The plane-parallel resonant cavity is built up in theory with the U-shaped bending waveguide for TM mode. The beam splitting and convergence effect are also discussed for the structure composed of filling-factor graded wave-like 2D-PC and one-dimensional multilayer thin films.

利用TM模的U型转弯波导构建了新型的平行平面谐振腔，并指出由填充率渐变型波状结构二维光子晶体和一维多层薄膜构成的混合结构在光分束和抑制光束发散方面的作用及其在平行平面谐振腔中的潜在应用。

It was demonstrated that the actin could be polymerized into discrete filaments of tree-like branch structure, random coil filaments cluster and long filaments with different diameters in F-buffer besides random aggregates. These polymerized filaments clearly exhibited the structural polymorphism and showed obvious difference from those assembled under the regulation by actin binding proteins or phalloidin.

研究发现，actin在体外通过自装配过程除了形成无序的蛋白堆积物之外，还能够聚合形成复杂的离散结构，包括树状分支的纤维丛、无规卷曲的纤维簇以及具有不同直径的长纤维等；这些大尺度纤维复合物明显不同于在ABPs或过量F-actin稳定剂参与下形成的由单根微丝和微丝束构成的聚合结构。

Time (3Xrpm) turning table speed. In addition, while the teeth of the tri-cone bit interact with the formation, the drillstring will generate tiny axial vibration. As the vibration is symphonious to the tri-spine well bottom, the vibration signal exhibits amplitude modulation character. This character had been verified by in-site measurement data and numerical simulation.

另外，三牙轮钻头与地层作用破岩时牙轮牙齿产生啮合振动，由于三脊状井底对啮合振动进行幅度调制形成调幅信号，根据调幅信号的频率特征，振动信号在频域表现为具有一定边带的一束谱线，它是钻头工作正常的&健康信号&。

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。
