The paper gives a fractal images compression algorithm deduced using best polynomial approximation, and two domain blocks searching path (variable step and nonvariable step), and proposes domain blocks incremental evaluation so as to increase the efficient of images compression.

本文还给出了我们用多项式最佳逼近方法导出的分形图象压缩算法，以及两种定义域块搜索路径，并提出了定义域块的增量计算思想，以提高压缩效率。

The general feature of deformation caused by the collision between two continents also reveals that, during the collision process, apart from a foreland basin and high mountains being formed, there is another compressive depression with an asymmetric structure developed on the side of the obducted plate, which is much easier to be formed when the dip angle of the collisional fracture zone is between 15° and 30° and is the deepest with a dip angle of 30°. This implies that the compressive depression is controlled by both subduction and obduction between two continents.

从大陆与大陆碰挂变形构造特征看，除发育前陆盆地－山脉系统外，在仰冲陆块一侧靠近造山带后缘还发育呈不对称结构的挤压性凹陷，当两个大陆板块碰撞断裂带倾角在15~30°时，该类型凹陷更容易形成，其中以30°倾角对应的凹陷最深，反映其形成可能是大陆碰撞过程中陆块之间相对俯冲和仰冲运动的综合结果。

In group A, VX2 tumor tissue was inoculated into the rabbit kidney percutaneously under ultrasound guidance.

新西兰大白兔30只平均分为两组，A组采用超声引导下组织块注射法，B组采用手术直视下组织块接种法建立VX2肾癌模型，比较两种方法的成瘤率，种植后隔天一次监测VX2肾癌的超声声像变化。

It is effective to treat patients with acute pelvic inflammatory disease without phlogistic mass by single antibiotic.

结果：无炎性包块组两种治疗方法的痊愈率、住院日无显著差异(P＞0.05)；有炎性包块组中西医结合治疗则明显优于西药治疗(P＜0.05)。

Root,immunoassay of ELISA(enzyme linked immunosorbent assay) was employed to determine IAA concentration in root tip, unilateral application of agar block containing IAA on root tip was carried out to investigate the effect of exogenous IAA on phototropic response.

为了研究生长素在水稻根负向光性反应中的作用，用含有IAA的琼脂块贴附在种子根的根尖表面观测IAA对根的生长效应，用ELISA法测定根尖的IAA含量，并对种子根弯曲部分进行半薄切片，结果表明：(1)种子根的生长方向既受光的调控也受外施的IAA的调控，根尖向贴有含IAA琼脂块的一侧弯曲生长；(2 )不定根在光照 1.5h后，背光侧的IAA含量明显大于向光侧；(3)种子根尖发生弯曲生长是伸长区的细胞不均等生长所致。

Anthers erect, with apical membrane overlying stigma head; pollinia 2 per pollinarium, margin translucent, caudicles enlarged at apex, erect.

花药直立，具顶端的膜overlying柱头头状花序；花粉块2 每pollinarium，半透明的空白边，花粉块柄放大在先端，直立。

Anther appendages membranous, ovate, overlying stigma head; pollinia 2 per pollinarium, oblong, horizontal, caudicles obliquely ascending.

花药附属物膜质，卵形，柱头头状花序；花粉块2 每pollinarium，长方形，水平，斜升的花粉块柄。

In trial 2, according to the similarity of calving date and milk yields, 25 primiparous Holstein cows were divided into five equal groups in a randomized block design with 49 days period. The general diet of dairy farm was fed to cows of control. The alfalfa block 2.7kgd^(-1 was substituted respectively by rice straw block Ⅰ,Ⅱ,Ⅲ or Ⅳ as treatments.

试验2，选取25头初产荷斯坦泌乳母牛采用随机区组设计按产犊日期、产奶量一致原则等分为5组，对照组用奶牛场常规日粮饲喂，试验Ⅰ、Ⅱ、Ⅲ、Ⅳ组分别用稻草块Ⅰ、Ⅱ、Ⅲ、Ⅳ等量替代苜蓿草块，每头替代量为2.7kgd^(-1)，试验期49d。

In order to prvoide the new clue for the later tapping oil potential of maturing oilfiled, especially for the stratagem adjustment of high water-cut inefficient exploitation reservoir, and prolongate the realm and orientation of tapping oil potential, the waterflooding characteristics and the law of remaining oil distribution were studied.

结果表明，该块油层水淹程度仅80%左右，剩余油在平面上分布于区块的绝大部分区域，且与构造高低无明显关系，纵向上主要集中于层段的上部，尤其是位于该块西北区构造低部位的北断层区潜力单元，是与目前老油田潜力区主要局限于正向型微构造区所不同的新类型与新领域。

Methods: Forty adult Wistar rats were used for these operations of transplantation of frozen autogenous tooth-mandible compound and fresh ATMC. Then the healing process after transplantation of frozen ATMC and fresh ATMC was compared by clinical, radiographical, histological and microangiographical observation.

选用健康成年Wistar大白鼠40只，任取2只用于观察正常颌骨的组织学图像，其余的大鼠随机分为新鲜移植组和冷冻组，行牙-下颌骨复合组织块移植到胫骨区的手术，分别于术后1、2、3、4、6、8、12、16、20周时处死动物，采用大体观察、X线片、组织学及微血管造影等观察手段对牙-下颌骨复合组织块移植后的愈合过程进行比较。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
