向地性的

Longitudinal root sections of the wild type and the gls mutant cultured in nutrient solution for 4 days showed that biosynthesis and distribution of amyloplast in the columella cells of gls were normal as compared with the wild type, suggesting that root gravitropism loss in gls mutant is not caused by the defect in amyloplast sedimentation, but possibly by the disturbance of auxin transport and distributation.

4天龄的根系纵切片结果显示：突变体gls根尖结构完整，根尖柱细胞内淀粉粒的生成和分布正常，表明gls突变体根系向地性的缺失不是由于淀粉体的原因，而可能通过影响生长素运输和分布造成。

These findings would be helpful to understand the molecular mechanisms underlying auxin regulation of root gravitropism in plants.

Iii By using the well-known properties of the dela vallee-poussin summability kernels and the pass principle of weakly compact operator, we study the weak compactness of C〓 on vector-valued analytic function spaces H〓, B〓, N and N〓, establish some connections between the weak compactness of composition operators and the structure properties of Banach spaces. These generalize and unify the corresponding results in the scalar-valued setting and enrich the content of the study of composition operator in another way.

第三，利用著名的de la Vallee-poussin可和核及有关算子的弱紧性的传递原理给出了向量值解析函数空间H〓、B〓、N及N〓上的复合算子的弱紧性的刻画，建立了复合算子的弱紧性与Banach空间的结构性质之间的联系，统一和推广了对应的数量值解析函数空间上的复合算子的弱紧性，这从另一种途径极大地丰富了复合算子的研究内容。

Using Hankel digital filter algorithm and inverse spine interpolation algorithm to simulate electromagnetic fields of the horizontal layers , we contrast the calculational Cagniard apparent resistivity with its results and field experimentation.

利用汉克尔数值滤波算法和逆样条插值算法对水平层状电磁场进行正演计算，并与计算的卡尼亚视电阻率的对比和野外试验结果表明：该方法的结果在远区等价卡尼亚电阻率，在近区和过渡带则明显地改善了卡尼亚电阻率的非波场区场畸变，从而能更好地接近基底的真电阻率，更形象地反映了地下介质的垂向电性变化。

The morphology of M2 and M3 was observed in hothouse and mutants on cotyledon and root of seedling, or embryo of seed were identified. The result showed that there were 8 types of mutative treats on cotyledon, including light-yellow cotyledon, yellowish cotyledon, trump-shaped cotyledon, multilobed cotyledon, non-cotyledon, single-cotyledon, tricotyledon and quadrcotyledon.

M_2和M_3的水培和形态学观察的结果发现，子叶性状出现浅色、黄化、喇叭形、多耳突、无子叶、单子叶、三子叶、四子叶等8种变异类型；根系性状出现短小根、发达根、无侧根和弱向地性等4种变异类型；种胚性状中发现了多胚变异。

消极感受力"这一范畴"消极"的背后蕴涵着最大的"积极"，积极地体悟美、积极地探索追求文学的本体，谦卑地将自己主体中心主义的意识隐去，还艺术以艺术的美感，使文学本体论的转向成为可能；"消极"的背后将主体的探讨引向更加宽广的领域，使一元主体中心论得以解体，使主体间性等对话意识成为可能；"消极"是对一切造物最大的尊重，对生活、对人类文化最"积极"地体味与感恩意识；"消极"与"积极一个在明一个在暗，交相辉映，成就了济慈对诗学本体的诉求，成就了诗歌领域伟大转向的可能，成就了张力的对话。

Horizontal canal benign paroxysmal positional vertigo is usually induced in supine position with head rotation towards either side. It is called geotropic form when the nystagmus is directed toward the undermost ear, or ageotropic form when the nystagmus is directed toward the uppermost ear.

水平半规管良性阵发位置性眩晕最容易发生在病人仰卧转头时，若眼振和转头方向一致，称为向地型，眼振方向和转头方向相反，称为逆地型，后者的治疗方法众说纷纭，文献上并无定论。

Topographic correction based on sun-canopy-sensor geometry is more appropriate than terrain-based corrections in forest areas because SCS preserves the geotropic nature of trees regardless of terrain, view, and illumination angles.

SCS校正模型解释了树木不依赖于地形、观测角和光照入射角而具有向地性生长的本质特性，但在某些地形区域，SCS与余弦校正同样存在过度校正的问题。

The head is slowly turned 90° toward the side where nystagmus is induced less intensely. Then the head is rotated 180° rapidly toward the opposite side. This article reports three cases of the ageotropic form of HC-BPPV that were cured by rapid head rotation. The three cases demonstrated that rapid head rotation was an effective maneuver to treat cupulolithiasis on the utricle side. It is recommended that rapid head rotation can be used for therapeutic diagnosis: If nystagmus subsides immediately after this maneuver, the diagnosis is cupulolithias is on utricle side. If nystagmus changes into the geotropic form, the diagnosis is cupulolithiasis on canal side or canalolithiasis in the anterior arm of horizontal semicircular canal. A repositioning maneuver for geotropic form can then be applied to treat these patients.

逆地眼振型水平半规管良性阵发位置性眩晕的3种耳石可能位置如下：水平半规管前臂的管耳石、管侧的顶帽沉石(canal side cupulo-lithias1s)与囊侧的顶帽沉石，本文报告3例以快速转头治疗逆地眼振型水平半规管良性阵发位置性眩晕成功的病例，显示快速转头法对囊侧的顶帽沉石具迅速有效的治疗效果，对於逆地眼振型水平半规管良性阵发位置性眩晕的治疗，作者建议先以快速转头作治疗性诊断，若病人马上复原，诊断为囊侧的顶帽沉石；若眼振转为向地型，则诊断为水平半规管前臂的管耳石或管侧的顶帽沉石，进一步再以向地型的耳石复位法治疗病人。

It's different with the tree milk, can not see obvious Gravitropism.
