存活率

The data indicated that the survival rates of unspread leaves are higher than that of mature leaves from larval stage to adult stage, and were 81% and 77% respectively.

统计表明：从幼虫到成虫整个阶段的存活率心叶较成熟叶片高，分别为81%和77%，椰心叶甲完成一个世代在心叶上需要58.54 d，在成熟叶片上需要52.92 d。

Results Using different concentrations of 5fluorouracil to deal with A549 cells, with the increase in drug concentration and treatment time,cell survival rate decreased significantly;and low concentration of 5fluorouracil induced the cell spread and increased vacuolization within the cytoplasm, acridine orange staining showed an increase in acidic vesicles,high concentration made the cell round and cell apoptosis.

结果不同浓度的5氟尿嘧啶处理A549细胞，随着药物浓度的增加和处理时间的延长，细胞存活率明显下降；且低浓度使细胞呈铺展状态，细胞质内空泡增多，吖啶橙染色显示酸性膜泡增多，高浓度使细胞变圆，出现凋亡状态。

Models based on morphological characteristi cs have been designed to help determine whether early survival is more likely af ter biventricular repair (surgical or balloon aortic valvotomy) or after a singl e ventricle staged palliative surgical strategy.

根据形态学特征已经设计出模型，以决定是双心室修复(外科或球囊主动脉瓣切开术)还是单心室姑息性手术新生儿的早期存活率提高。

The survival and pupation rates of over-wintered SSB collected from rice field were 67.30%and 70.06%,much higher than SSB collected from Zizania fields.The emerging rates were similar between SSB collected from both habitats.

水稻田二化螟越冬幼虫的存活率和化蛹率分别为67.30%和70.06%，茭白田二化螟则分别比其低20.90%和21.69%；二者的羽化率差不多，分别为90.28%和89.19%。

He began with bladder cancer and that staging correlates with disease specific survival.

他从膀胱癌和与存活率密切相关的分级开始。

The results showed that with the extension of AVM treatment time, the relative neuron survival rate and the mitochondria fumaric reductase activity decreased, the percentage of neuronal apoptosis increased, the mitochondria swelled, the mitochondrial structure was damaged, cristae were broken and dissolved and there were vacuoli in base.

结果显示，随着染毒时间的延长，细胞的相对存活率下降；线粒体琥珀酸脱氢酶活力降低；PI-/Rh123-细胞百分数增加；线粒体肿胀，结构不清晰，嵴断裂、溶解、基质中有片状空腔现象。

Additionally, MCF-7 cells were incubated in L-arginine-free medium with 10% dialyzed FBS for 1-7 days to measure their cell viability by using MTT assay.

另外再以含有10％透析过FBS的L-arginine缺乏培养基培养MCF-7细胞1-7天后，以MTT assay测定其细胞存活率。

Each male ratwas paired with 2 female rats in proestrus when administration terminated. Femalerats were examined the next morning for the presence of sperm in vaginal smears andunderwent a cesarean section on day 13 of gestation. Then the reproductive indiceswere calculated as follows: copulation index, pregnancy index, and fertility index,which can evaluate male fertility directly. The sperm motility and morphology wereevaluated by computer-assisted sperm analysis, moreover, the caudaepididymal sperm ultramicrostructure were analyzed by transmission electronmicroscope, which can evaluate the influence on sperm maturation bydutasteride ; sperm survival rate was assessed by SYBR-14 and propidium iodidefluorescent staining; serumal dihydrotestosterone and testosterone of ratswere detected by enzyme-labeled immunoassay, which can evaluate the effecton androgenic levels; the weights of testes and epididymides, were determined byprecise electronic balance; histological examination of above tissues were evaluatedby HE staining and TEM, which can evaluate treatment on histology of reproductiveorgans by dutasteride.

给药结束后雄鼠与处于动情前期的雌鼠按2：1合笼，计算雌鼠的交配指数、受孕指数和生育指数，直接评价雄鼠生育力；采用计算机辅助精子分析系统分析大鼠附睾精子活力和形态，在此基础上合并使用透射电镜技术对各组附睾尾部精子进行透射电镜分析，评价度他雄胺对大鼠精子成熟的影响；采用SYBR-14和propidium iodide双重荧光染色计算精子存活率；采用Elisa法测定大鼠睾酮(testosterone， T)和双氢睾酮(dihydrotestosterone， DHT)血清浓度，评价度他雄胺对雄鼠雄激素水平的影响；采用精密电子天平对各组睾丸、附睾、前列腺和精囊进行称重，评价度他雄胺对大鼠生殖器官重量的影响；采用HE染色法对各组睾丸和附睾进行组织学分析，同时采用透射电镜技术对附睾上皮细胞超微结构进行分析，评价度他雄胺对大鼠主要生殖器官组织学的影响。

To get around such problems, some analysts compare not life expectancies but survival rates from different diseases.

为了解决这些问题，一些分析人士不仅比较预期寿命，还对不同疾病的存活率进行比较。

To get around such problems, some analysts compare not life expectancies but survival rates from different diseases.
