管

With the advent of May,as if there is a mission for me to take on-it's time to find a girlfriend ,a majordomo girlfriend who will be in charge of my family,my eating,my drinking,my sleeping,my pastime,and my work.

进入5月后，仿佛有种使命肩负在我的身上一般，我该找个女朋友了，该找个管家了。该找个管我吃、管我喝、管我睡、管我娱乐、管我工作的管家女朋友了。

The results showed that the four treatments of cytochrome c supplemented with ATP all suppressed the pollen germination and pollen tube growth, and induced nuclear DNA degradation, different treatments with different ratios of double nuclei, single nucleus, and no nuclei. Treatment with heavy concentration of ATP also restrained pollen germination and pollen tube growth, but can not induced nuclear DNA degration.

结果表明，细胞色素c和ATP混合处理的四个组合都能抑制离体花粉萌发和花粉管生长，并且引起了花粉管核DNA的降解，不同处理中双核、单核及无核花粉管所占比率存在明显差异；高浓度ATP虽能抑制花粉萌发和花粉管生长，但不能引起花粉管核DNA的降解。

Taking HPAM solutions as an example , the unsteady flow of power-law fluid in eccentric annuli with the inner cylinder reciprocating axially is calculated; the distribution of velocity, flow rate and:stress distribution on the outwall of the inner cyinder is obtained; the effect of eccentricity, stroke and frequency on distribution of velocity is analysed; the effect of eccentricity and axial movement on stress distribution on the outwall of the inner cylinder is analysed too.

在计算上，以HPAM水溶液为例，数值计算了幂律流体在内管做轴向往复运动的偏心环空中的流动，得出了这种流动的速度，流量和流体在内管壁上的压力分布；分析了环空偏心度以及内管冲程和冲次对流体速度分布的影响；分析了环空偏心度和内管轴向运动对流体在内管壁上压力分布的影响。

Taking HPAM solutions as an example, the unsteady flow of power-law fluid in eccentric annuli with the inner cylinder reciprocating axially is calculated; the distribution of velocity, flow rate and stability parameter is obtained; taking HEC solutions as another example, the flow of second order fluid in eccentric annuli with the inner cylinder moving axially is calculated too; the distribution of velocity and stress is obtained; the effect of eccentricity and axial movement on stress distribution on the outwall of the inner cylinder is analysed.

在理论上，分别用二阶流体和幂律流体模型描述聚合物驱油井产出液的非Newton流变性；分别建立了双极坐标系下二阶流体和幂律流体在内管做轴向往复运动的偏心环空中非定常流的控制方程及边界条件和初始条件方程；建立了幂律流体在内管做轴向往复运动的偏心环空中流动的稳定性参数和流体在内管壁上的压力分布计算公式；建立了二阶流体在内管做轴向运动的偏心环空中流动的流体在内管壁上的压力分布计算公式。

Pipe wrench dogs within each pipe rack pot are used to loosen the pipe from the rotary head coupling, when return-ing drill pipe to the rack.

当将钻管放回管架上时，用每个管架罐内的管钳爪将管子从转动管接头上松开。

Results showed: in Podocarpus leaves, there is only one midrib, the xylem tracheid of midrib vascular bundle is multi-form, transfusion tissue belongs to Cycas-type and transfusion tracheids are isodiametric, the accessory transfusion tracheids between palisade tissue and sponge tissue are developed; in Nageia leaves, there are plenty of parallel leaves, the xylem tracheids of each vein are relatively simple, transfusion tissue belongs to Taxus-type and transfusion tracheids are longer in longitudinal section than that in transverse section, the accessory transfusion tissue between palisade tissue and sponge tissue is absent.

结果表明：罗汉松属叶1条主脉，主脉维管束木质部管胞发达，转输组织为苏铁型，转输组织管胞等径，栅栏组织和海绵组织之间的副转输组织管胞发达；竹柏属叶多条平行叶脉，维管束木质部管胞相对不发达，转输组织为红豆杉型，转输组织管胞纵向伸长，栅栏组织和海绵组织之间不存在副转输组织。

Because the conical resonance tube can enhance shock waves, the gas at the end of the conical resonance tube has higher pressure oscillation amplitudes and higher temperatures and heating rates than that at the end of the cylindrical resonance tube.

因为圆锥形谐振管对激波有增强作用，所以在相同条件下，圆锥形谐振管中气体压强的振荡幅度和加热温度、速度都要高于圆柱形谐振管，因而圆锥形谐振管加热性能比圆柱形谐振管好。

Acquired conclusion was that the sample mean value submitted to normal distribution, and the sample variance was composed of a number of linear sum of random variable submitted to Chi-Squared distr.

得出的结论是：样本均值服从正态分布，样本方差由若干个服从卡方分布的随机变量的线性之和组成；样本均值的期望等于各管落点期望的算术平均值，方差为各管方差的算术平均值；样本方差是各管落点总体平均方差的无偏估计，方差与各管落点散布的差异相关；样本均值与方差相互独立的充要条件是：各管落点属于独立同分布样本。

Moreover, since the strain energy of zigzag tubes is larger than that of the armchair tubes with the same semidiameter, the ends of the armchair tubes are easier to be closed than those of the zigzag ones. And the closed structures of the zigzag tubes have a lot of defects, even at 3000 K, there will be few carbon atoms flying away from them.

此外，由于锯齿型碳管应力能比同口径扶手型碳管的应力能大，使得扶手型碳管比锯齿型碳管更容易形成端口封闭的结构，且锯齿型碳管端口的封闭结构出现相对较多的缺陷，甚至在3000K下会有少最碳原子从端口飞离碳管。

One, suck phlegmy the preparation before works 1 should make sure negative pressure attracts plant above all each conduit joins correct, close together, unobstructed, assure significant negative pressure, general adult 10.64~15.96Kpa, the baby should be controlled in 7.98~10.64Kpa. 2 preparation rinse the asepsis physiological saline that smokes phlegmy pipe 2 bottles, 1 bottle wash pump technically with Yu Chong the suction inside tracheal spile is phlegmy canal , additional 1 bottle rinse those who had sucked mouth, nasal cavity technically to smoke phlegmy pipe . 3 equipment are very different the asepsis of model sucks phlegmy canal and asepsis glove. 4 because suck phlegmy itself,be a kind of stimulation to the patient, sober patient is not willing to suck normally phlegmy, and the family member of insensible patient also thinks to suck phlegmy special anguish.

一、吸痰前的预备工作1首先要保证负压吸引装置各管道连接正确、紧密、通畅，保证有效的负压，一般成人10.64~15.96Kpa，婴儿应控制在7.98~10.64Kpa.2预备2瓶冲洗吸痰管的无菌生理盐水，1瓶专门用于冲洗抽吸气管插管内的吸痰管，另1瓶专门冲洗吸过口、鼻腔的吸痰管。3备好不同型号的无菌吸痰管及无菌手套。4由于吸痰本身对病人是一种刺激，清醒的病人通常不愿意吸痰，而昏迷病人的家属也认为吸痰非凡痛苦。
