Methods Hela cells of human cervical cancer were cultured with mitomycin C in gradually increased dosage in order to obtain a drug-resistant Hela/MMC cell subline. The biological properties of Hela and Hela/MMC cells were compared and the mechanism of drug-resistance of Hela/MMC cells studied.

以人宫颈癌Hela细胞为亲本，采用丝裂霉素连续性药物作用，间隙性增加药量，逐步提高药物浓度的方法，分离出MMC耐药亚系，并比较两种细胞生物学特性差异。

"Half the blueberry plant is underground rhizome system," Yarborough explains, burn off, you get these new sprouts .

"蓝莓植株本身有一半作为根茎系长在地下，"亚伯勒解释说：当你焚烧这些植物后，从地下的根茎上便更容易长出更多嫩芽。

Hydroxyapatite acerate nanoparticles with mean size ranging form 20~50nm are synthesized by the impinging stream devise using emulsion systems consisting of aqueous phase, cyclohexane as the oil phase and OP-10, n-octanol as the nonionic surfactant in definite pH value.

在一定pH值条件下，采用水溶液/环己烷/OP-10/正辛醇四元反相微乳液体系并结合撞击流技术制备出粒径为20~50nm的针状纳米羟基磷灰石晶体。

According to core observation and description, many deformation structures with seismite characteristics are recognized within sandstone and shale sedimentary strata of Paleogene continental faulted basin in Yangxin Subsag, such as micro-faults, earthquake fissures, liquefaction sandstone veins, water-escape structure, vibrational liquefaction deformation structure, seismic pillow structure and associated structure, etc. The vertical sequence of seismites in Yangxin Subsag, in ascending order, is underlying unshocked layer, micro-faults layer, autoclastic shattered breccia layer, vibrational liquefaction deformation structure layer, seismic pillow structure and associated structure layer, liquefied homogeneous layer and overlying unshocked layer, which corresponds to different earthquake intensity respectively.

通过岩心观察和描述，在阳信洼陷古近系陆源碎屑断陷湖盆砂泥质沉积地层中识别出大量具有震积岩特征的变形构造，如微断层和震裂缝、水下岩脉和泄水构造、振动液化卷曲变形构造、震积枕状层及伴生构造等，同时建立了阳信洼陷震积岩垂向序列，自下而上分别是下伏未震层段、微断层层段、震碎角砾岩段、振动液化卷曲变形层段、震积砂枕及伴生构造层段、液化均一层段和上覆未震层段。

For example, the phylogenetic trees constructed by NJ, ME, or MP methods basing on 12S rRNA complete sequence, indicated Falconidae branched off prior to the other avian, but the UPGMA tree placed Falco peregrine into a single branch and formed sister group with Accipitridae species and Strigiformes specie.

在基于12S rRNA全序列构建的NJ、ME和MP树中都支持隼科最早分化出一个单系群，而在UPGMA树中，隼科游隼单独形成一个分支，与鹰科、夜鹰目和鸮形目互为姐妹群。

60Co-γray was a useful mutagen in induced mutation breeding .After treated with 60Co-γray ,free-living conchocelis of wild Porphyra haitanensis were induced and represented in offsprings. Purple mutant and excellent practical characters strains were selected from a lot of gametophytic blades. Single cell clone and enzymolysis were used to propagate fast in pure strains of induced mutations.

坛紫菜野生丝状体经一定剂量60Co-γ射线辐照后，子代叶状体发生了变异，经大量培养后筛选出紫色突变体（3号Ⅰ）和经济性状优良的个体（7号Ⅰ和7号Ⅱ），通过体细胞酶解和单克隆技术快速获得诱变选育纯系，并对其主要经济性状进行了研究。

Since the analytical solution was derived under the condition of an-infinitely wide slope, the shape of parabolic sections of general grassed channel needs to be considered. This work uses the results of Hey (1979) to build the shape factor, which can be used to design a grassed channel with a parabolic section.

但因其解假设条件为无限宽敞的渠道，而一般草沟设计则常用抛物线形断面，本研究用Hey(1979)找出修正形因子之系，可应用於设计草沟之水分析。

Based on seismic section explanation of thousands of kilometers, the authors selected 4 seismic parameters (frequency, swing, continuity and inner reflect configuration), adopted multiple nomenclative principle of seismic facies of "figure+configuration+swing+frequency+continuity" and generalized 10 seismic and 5 sedimentary facies for the northern sag of South Yellow Sea Basin.

在数千公里地震剖面解释基础上，选用频率、振幅、连续性及内部反射结构等4个地震参数，采用&构形+结构+振幅+频率+连续性&的地震相复合命名原则，总结出南黄海盆地北部坳陷白垩系近10种地震相单元，5种沈积相类型。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
