The results show that the urban heat island area of Beijing city is strip shaped and ring shaped. Lower elevation and smaller slope are favorable to form the urban heat island, and the various land cover types have dramatically different thermal properties.

结果表明，北京市热岛分布具有环状和带状分布特征，高程较低处和坡度较小处更容易形成热岛中心，不同地表覆盖类型的热特征具有显著的差异。

As to the visualization study, the emergence of great deal of bubbles is observed when the wall superheat is low.

可视化研究发现低的壁面过热度时，有大量气泡产生；在本实验范围内，微槽内沸腾的流型主要有塞状流和环状流两种。

First, a method based on creating peaks circularly and symmetrically in the DFT domain is proposed to resist rotation and scaling attacks.

首先，利用在离散富利叶转换频域上产生环状和对称的峰值来抵抗旋转和缩放的攻击。

The result showed that the plant of Maicao No. 9 was tall, with good fecundity, fully filled grain and vigorous growth. The chromosome number of the root cells was 2n=56, through the observation of pollen mother cells meiosis, there were a certain amount of univalents, ring bivalents and bar bivalents in PMCM. Different numbers of lagging chromosomes, chromosome bridges and micronucleus were found in anaphaseⅠ, anaphaseⅡ and tetraspore.

结果表明：麦草9号植株高大，结实性较好，籽粒饱满，生长旺盛；根尖细胞染色体数目为2n=56，对其进行花粉母细胞减数分裂观察，中期Ⅰ具有一定数量的单价体、环状二价体、棒状二价体；后期Ⅰ、后期Ⅱ与四分体时期都出现不同数量的落后染色体、染色体桥、微核等现象。

Widening of the cricothyroid space in 15 cases (68.2%); 4. thyroid cartilage destruction in 12 cases (54.5%); 5. lymph node metastasis in 16 cases (72.7%). Mass effect from bulky pyriform sinus tumor distorted the adjacent normal structures, simulating tumor involvement in some instances and causing 8 false positive CT findings in our study.

综合主要的CT表徵包括：(1)扩展到喉外软组织有16例(72.7%)；(2)蔓延至会厌前空间(pre-epiglottic space)有12例(54.5%)，但只有3例越过中线；(3)环状甲状软骨空间变宽有15例(68.2%)；(4)甲状软骨被侵蚀破坏有12例(54.5%)和(5)淋巴结的转移有16例(72.7%)。
