定向的

For the numble of people taking part in is not very large and people felt a little tired after a long time cross-country race,we only selected two or three games.

由于参与人数不是很多，并且大家在一个长时间的定向越野后有些疲劳，原定的团队游戏就只挑了两三个进行，不过大家玩的还是比较开心。

In this study, the structure sequences of Shiga toxin 2B(stx2B) and Shiga toxin 1B(stx1B) were respectively amplified from EHEC O157:H7 by PCR. stx2B-L-stx1B fusion gene was constructed by a 12 bp linker ligating these two fragments. After digested with restriction endonuclease Nco Ⅰ and EcoR Ⅰ, the fusion gene was orientally inserted into expression vector pET28a.

利用PCR方法，从肠出血性大肠杆菌O157：H7的基因组DNA中，分别扩增出Stx1B和Stx2B亚基的结构基因片段，然后再通过PCR将这2个片段连接起来，并定向克隆到表达质粒pET28a的NcoⅠ和EcoRⅠ位点之间，构建了重组表达质粒pMB1。

Orthogenic life advanced in a direct line, from organism A through the alphabet of life to organism Z.

定向进化Orthogenic的生物沿着一个直线方向发展，就像沿着字母表演化，从最早的生物A一直演化成最后的生物Z。

However, hair follicle stem cells prefer hair destiny in vivo, unless the injury of epidimal or sytogland occurs. In 1990, Cosarelis et al. proposed "The Bulge activated hypothesis", they think the signal moleculars emit from the dermal papillar induce the downward migration and differentiation of hair follicle stem cells.

然而，体内正常情况下毛囊干细胞首先向毛发谱系定向分化，只有在表皮或皮脂腺受到损伤时，它们才进行程序重组而向表皮或皮脂腺方向分化。1990年，Cosarelis等提出毛囊的&隆突激活假说&，认为来源于毛乳头的信号因子触发了毛囊干细胞向下迁移并分化，从而维持了毛发周期的正常循环。

These peridotitic xenoliths show clear deformed textures and their major minerals show excellent orientation.

橄榄岩捕虏体具有明显的的变形结构，矿物定向排列，属于典型的变形橄榄岩。

These peridotitic xenoliths show clear deformed textures and their major minerals show excellent orientation. Thus, these peridotites are typical deformed peridotites.

橄榄岩捕虏体具有明显的的变形结构，矿物定向排列，属于典型的变形橄榄岩。

Methods from Sept 2000 to March, 2002 516 patients with body tumor were therapied. The radiotherapeutic plan and set dosage distribution had been worked out on the basis of the carcinoma position, clinical target volume, patient health condition, and therapeutic aim. The isodosage curve was 50-90%. The fractional doses was 300-900cgy. The therapy had been repeated for 5-9 times for one patient, every two days one time. Results the patients were followed up 3 to 15 months after therapy.

采用OUR-QGD立体定向伽玛射线体部放射治疗系统治疗肿瘤患者516例，根据肿瘤的部位、临床靶体积大小、分类与治疗目的，如临床根治或姑息治疗，以及肿瘤周围的组织与器官、病人的身体状况、既往治疗情况、有无淋巴结转移等制定放射治疗计划及调整剂量分布， PTV覆盖95%以上CTV，等剂量曲线50~90%，中位值62.2%。

In the deep processing of agricultural and food products, there are some key technological problems of system design on the domestic traditional reelable vacuum aluminium coating system, including mass process parameters, bad process duplication, unstable production quality caused by complex operation, and high equipment failure rate. A newly developed reelable vacuum aluminium coating system with 1500 mm-wide thin plastic films was designed with high vacuum technology in order to satisfy the vacuum aluminum coating of more than 1500 mm-wide, such as polyethylene terephthalate, oriented polypropylene, polypropylene cast film, polyvinyl chloride.

为满足农产品及食品深加工中1500 mm幅宽以上的聚脂薄膜、定向聚丙烯薄膜、聚丙烯流涎薄膜、聚乙烯薄膜的真空镀铝，针对国内卷绕蒸发式真空镀膜机设备存在的工艺参数多、工艺重复性差、操作复杂、产品质量不稳定、设备故障率高等问题，采用高真空技术研制了宽幅卷绕蒸发式高真空镀膜机。

Due to high-quality requirements of scientific exploration well,long open-hole,long coring footage,and frequently changing lithology,the length of inner tube shoe was increased,the surface slippy degree between core catcher and inner tube sh...

针对科学探井对岩心质量要求高及该井裸眼井段长、取心进尺长、地层岩性变化频繁、取心施工难度较大等问题，采取加长刻刀座轴向长度，增加岩心爪与刻刀座表面光滑度，优选取心钻头，调整钻井液性能和选择配伍性好的钻头与刻刀座、合理的钻进参数等措施，保证了定向取心收获率，取心累计进尺103.66 m，收获率99.85%，为科学研究提供了可靠的岩心资料。

This paper presents a nonlinear analysis of the stresses in jointed rocks around a subterranean structure by the initial stress method. In this analysis, rocks with a parallel set of joints of a given predetermined orientation are idealized as a stratified. material with no shear between the strata j and rocks with a random set of joints are idealized as a tensionless material.

本文将具有一组定向节理的岩体理想化为层面不抗剪材料，将具有随机分布节理的岩体理想化为不抗张材料，采用初应力法，对节理岩体内地下工程围岩应力做有限元非线性分析，编制了通用程序，并根据某水封石洞油库的实际参数作了算例。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
