There are numerous genera here which are endemic to East Asia and to China,and many genera with East Asian - North America disjunct distribution.

北美间断分布属和中国特有属，它们既是本地植物区系的特色，也代表了中国植物区系的核心。

A 512 byte area of disk storage. Each disk sector contains two 256 byte disk data blocks.

一个512字节的磁盘存储区，每个磁盘扇区含有两个256字节的磁盘数据块。

According to the physics sector, disk sector read.

根据给定的物理扇区号读取磁盘扇区。

The virus is used to guide its own to replace the original disk boot sector code, and the virus into memory.

而引导区病毒则用它自身来代替磁盘上原来的引导区代码，并将病毒装入内存。

Methods All 6 cases had endophthalmos and blepharophimosis. Four cases also complained of diplopia. The horizontal and coronal CT of orbit showed the lamina papyracea fracture clearly.The degree and range of the lamina papyracea displacement was measured on CT films.The reduction under nasal endoscope was performed with local and topical anesthesia. We selected the Meeserklinger＇s route of entry.The uncinate process,ethmoidal bulla,and ethmoidal cells were removed successively.Then,with the help of a tonsil dissector, the lamina papyracea was pushed outward and replaced and was supported with iodoform gauze.After 2 to 3 weeks,the gauze was removed.

对6例伴有眼球凹陷、睑裂变小及复视等症状、眶部CT扫描均显示纸板击出性骨折的患者，在确定骨折位移程度及范围后，在局部麻醉＋鼻粘膜表面麻醉下行鼻内窥镜经筛窦纸板骨折复位术，手术采用常规Meeserklinger入路，小心咬除骨折区筛房，显露骨折区纸板，用钝性剥离子，由前向后将内移的纸板外推复位，局部碘仿纱条填塞支撑，2～3周去除填塞纱条。

Origin, developmental changes and homologies of the stage morphostructures were considered according to their location in three morphogenetic fields. The first, or central, field forms at the prodissoconch I stage. It can be inherited by prodissoconch II and nepioconch stages in one taxa, or PD-II, N and dissoconch stages in others. The second, or postero-dorsal, field appears at the N stage, and the third field, or antero-dorsal, at the D stage.

主要对3个形态发生区域的阶段形态结构的起源、发育变化和同源性做了研究，其一，即中央区域，开始形成于前双壳I期，在某个分类单元它可以在前双壳II期和幼贝期形成，而在其它分类单元则在前双壳II期、幼贝期和双壳期形成；第二区域，即背部后区，在幼贝期出现；第三区域，即背部前区，出现于双壳期。

Firstly, four beams are formed using wideband distortionless beamforming method, which divides the whole space into four separated regions. Then the beam outputs are calculated and taken as the signal received by a reference point.

该方法首先预形成指向4个方向的宽带无失真波束，各自的主瓣区域把整个空间分为4个不同的测量区，然后分别将这4个波束形成器的波束输出作为参考点接收到的声信号，利用基于时延的定向方法定向处于不同测量区的声源。

By the swimming pool area and diving area, two districts with each other is China Unicom, also an independent self-organized event.

游泳馆是由游泳比赛区和跳水区组成，两个区既相互联通，又可自成一体独立举办赛事。

Of course, this "everyone" and all those people, we all know very well ah - is "dollar zone" and the "euro, dollar general area" of the country, there are some contradictions in the chinese state has a border such as india.

当然啦，这"一大伙人"都是些什么人，大家也心知肚明啊——都是"美元区"和"欧元、美元通用区"的国家，也有一些和中国有着边界矛盾的国家，诸如印度等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
