The depth of central-axis percent dose Rx (except R100) and practical range, Rp, for small field electron beams can be calculated by the proposed empirical formula: Rx = Rxo ×,where Rxo R po are the broad beam percentage dose depth and practical range respectively; r is the small field cutout side when it is less than the maximum lateral scatter equivalent range, and m is he exponent term relative to the decreasing curvature.

小照野电子射束中心轴百分剂量深度，Rx（R100除外），及穿透深度，Rp，可以用本文提出的经验公式：Rx = Rxo×计算求得，其中Rxo及 Rpo分别为宽射束百分剂量深度及实际穿透深度；r为边长小於最大侧散射等效范围的小照野边长；m值为与下降曲度有关的指数项。

With the development, both the numbers of pigment granules and the numbers and kinds of the organelles in the cell increased gradually, the diameter of the rhabdom and distance between the rhabdoms of the ommatidia increased too. The fine structure indicated that larva obtained the function of the light sensation gradually.

随着发育，幼体小网膜细胞内的色素颗粒、细胞器种类和数量、组成感杆束的微纤毛数量、感杆束的直径和间距等均有逐渐增加的趋势，表明复眼的感光结构是逐渐完善的。

During light adaptation, the diameter of rhabdoms was small, the arrangement of microvillus in the distal rhabdom was in disorder, and the area of the multivescicular bodies in the cytoplasm of the retinular cells was large, but the perirhabdomal vacuoles was very small, the amount of the lamellar bodies and mitochondrias were small, the pigment granules were distributed in all retinular cell.

结果显示：光适应时感杆束的直径较小，组成近远端感杆束的微纤毛排列零乱；小网膜细胞中的多囊体体积增大，膜下储泡囊体积减小，板膜体、线粒体等细胞器数量较少，色素颗粒分布于整个小网膜细胞。

OBJECTIVE: To meet the needs of limited and high selective spinal dorsal rhizotomy, anterior and dorsal root of spinal nerve were microanatomized to be certain of the separation standard and the number of small nerve tracts, so as to provide reliable basis and novel operative standard for clinical operation.

目的：根据限制性和高选择性脊神经后根切断术的要求，对脊神经前后根进行显微解剖，确定神经小束的分束标准和数目，为临床手术提供可靠的依据和新的手术标准。

This paper proposes that willow bushes are used to prepare plate,and introduces the experiment and results.Fiber reinforced technology is introduced into scriber's reinforcement.

纤维束定向板材(也称重组木Scrimber)是近30年来，国内外人造板研究发展的最新技术，它是利用横向不断裂、纵向连续的木束，经干燥、铺装、施胶和热压而成。

The length,width,thickness and weight of the current year and more than one-year-old needles of both bi-needle-cluster and tri-needle-cluster of slash pine were measured to expose the differences in terms of leaf shape and specific leaf area,and leaf area index was estimate based on measurement of the plantation in Qianyanzhou Ecological Station.

对湿地松当年生和多年生两针一束、三针一束叶片的长度、宽度、厚度和重量分别进行量测，据此探讨不同类型叶片的叶形和比叶面积差异，并结合样地调查数据对中科院千烟洲试验站湿地松人工林的叶面积指数进行计算。

A set of emitter which slenderize the acoustic wave has been designed, and also a set of receiver which select the scattered acoustic wave according to the position of the scattering particle has been designed.

研制出的发射传感器和接收传感器，能够分别产生细长的发射声束和接收声束，使信息窗区域面积能够控制在很小的范围内，位置也被控制在设计值处，满足了分区测量的要求。

But, however, on the contrary, neverthelessThey looked very well in their simple suits, Meg's in silvery drab, with a blue velvet snood, lace frills, and the pearl pin.

A 3-D solid unit cell geometry model is developed, the characteristics of geometry are studied and yarn-jamming condition is discussed.

该几何模型考虑了纤维束在内部、边界及边角的不同交织方式，纤维束在整个编织过程中的连续性，保证了三维编织复合材料的结构完整性。

Because ureamolecules replace some water molecules that solvate the hydrophobic chain and thepolar headgroups of the surfactant, urea slightly decreases the micropolarity andstrongly increases the microviscosity of the micellar interface.

尿素的加入，大大提高了胶束界面的微观粘度，而稍微降低了胶束溶液的微观极性。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
