Experimental results show that there are existing some indifferent mechanisms to the pollen sterilization of the Ms types: during the period of single nucleic to three nucleic pollen cell,we observed that the cell of xylem and phloem in anther septum abnormally developed,also the cell in the sheath of vascular bundle,smaller and arranged irregularly; the metabolic block developed too,es...

结果表明，不育类型的花粉败育有着一些共同的机理：在花粉单核期至三核期可见到花药隔维管束的木质部及韧皮部细胞发育较差，维管束鞘细胞发育不良，体积较小，排列紊乱；在单核花粉期至三核花粉期均发生物质代谢障碍，特别在花药部位尤为明显；由于维管束发育不良和花药物质代谢障碍，导致了花粉缺乏营养而败育。

The result show that the effect sequence of irrigation in cotton field on CDS is FBFS＞BS＞BBOS＞BOPS.

研究认为，棉花田间灌溉的时期对产量的效应顺序为：花铃期＞蕾期＞吐絮期＞盛絮期。

Roots grew preferentially, R/S ratio and phosphorous utilized efficiency are high; As the treated time prolongs, rubber mini-seedling buddings under the treatment of phosphorus deficiency is seriously restrained.

抽生期、古铜期和成熟期根系可溶性糖大量合成蛋白质，IAA含量高、iPA含量低，根系活力强，说明根系生长快、代谢旺盛、吸收能力强；淡绿期、稳定期则相反。

The limitations of two kinds of life tables, time-specific life table and age-specific life table were analysed and resolved. The limitation of time-specific life table could be solved by adding the survival rate of immature stages.In age-specific life table, the durations of each stage and the whole generation could be calculated by a formulary detruded from the life table, and rmcould be got from the generation duration.

针对特定时间生命表和特定年龄生命表两种编制方法中存在的不足进行了分析，并提出了可行的解决办法，即在特定时间生命表中导入幼期存活率，在特定年龄生命表中根据推导出的历期公式计算各个虫龄的历期，得到世代平均历期T，进而得到rm值。

Dichlorvos to the 25, 26 and 35 period tadpoles is of medium toxicity, while it is highly toxic to the 42 period tadpoles.

由此得出敌敌畏对25期、26期和35期蝌蚪属中等毒性，对42期蝌蚪则表现为高毒。

The level of the ECL and the PHA-L receptors as higher at the estrus than that at the diestrus. ECL and PHA-L receptors maintained the lower level at the day 4 and 5 of pregnancy than those at the diestrus.

ECL和PHA-L受体水平在动情期高于动情间期，孕期呈现先下降后上升的趋势，且在孕4、孕5d的水平显著低于动情间期和动情期（P＜0.01）。

ResultsIdiopathic nocturnal frontal lobe epilepsy has distinctive clinical seizure characteristics. The onset age is younger than 20 and the ratio of male cases to female cases is 2 to 1. The most notable clinical characteristics are nocturnal clustered postural or dystonic seizures and complex motor activities, with 14% of the patients have epileptic family history. The interictal routine EEG of 22.9% and active EEG of 28% cases in wakeness and 38% cases in sleep showed frontal lobe epileptiform discharge while the ictal EEG of 66.7% cases showed frontal lobe epileptiform discharge. Drug therapy is effective in 80% cases with 30% completely controlled.

结果 特发性夜间额叶癫痫具有特征性的临床发作特点，大多数于20岁之前起病，男女比例2：1，以夜间成串的偏转性、姿势性强直及过度运动发作为最显著的临床特征。14％有阳性癫痫家族史。22.9％清醒发作间期常规脑电图及28％清醒发作间期动态脑电图可见额叶癫痫样放电，38％患者的睡眠发作间期动态脑电图可见额叶癫痫样放电，66.7％患者的发作期脑电图可见额叶癫痫样放电。80％药物治疗有效，30％可完全控制。

Abstract］ Objective To investigate the change of bronchial mucosa cilia epithelium structure on children with recurrent respiratory tract infection in acute stage and convalescence stage.Methods Choose 38 cases of patients with RRTI as study group,respiratory ciliated cells were collected by bronchial fiberscope in acute stage and convalescence stage respectively,observe the change of cilia structure by electron microscopy and compare the incidence of cilia cylindrical epithelium structure abnormality.

摘要］ 目的研究反复呼吸道感染患儿急性期与恢复期支气管黏膜纤毛上皮结构的特点与变化，临床治疗的有效性提供客观依据方法选择符合儿童RRTI诊断标准的患儿38例作为研究对象，分别于急性期及恢复期在纤维支气管镜下夹取支气管黏膜组织，电镜下观察纤毛上皮结构的特点并比较纤毛异常的发病率，探讨RRTI患儿治疗后纤毛的恢复情况。

E The fractal and spherical particles exist favorably in the coarse fraction, while in the fine mode (0μm) are floccules formed by flocking fine particles together, containing crustal elements and mainly being silicates and aluminosilicates. f The content of Al, Si, Fe in TSP samples is higher than in PM〓, indicating an enrichment of these elements in coarse mode. g Compared with non-dust particles, the dust particles are more homogeneous in terms of morphology, particle size and composition. h Particles with irregular shape and well-distributed size dominate in dust samples, containing crustal elements such as Mg, Al, Si, Ca, Fe et al.

细粒中除小圆球外，大多为细小颗粒聚结在一起的不规则块状颗粒，主要含地壳元素，可能是硅酸盐和铝硅酸盐。fMg、Al、Si、Fe在PM〓中的含量较相应的TSP中的低，可见这些元素主要存在于较粗颗粒中。g沙尘期气溶胶粒子的形貌较非沙尘期单一、均匀，非沙尘气溶胶粒子的形貌、组分较沙尘期复杂。h沙尘期样品中，粒径均匀、形状不规则的颗粒最多，这些颗粒主要含地壳元素Mg、Al、Si、Ca和Fe等，是典型的由源区传输过来的沙尘粒子，但其高硫含量表明在青岛特殊的地理环境下，在粒子表面发生了硫的均相和非均相反应。

The results show that follicular cells originate from non-germ cells,and its whole development process can be divided into four stages:scattered cell stage,unilayer flat cell stage,multilayer flat cell stage and granule cell secretion stage.

结果表明，滤泡细胞起源于非生殖细胞，并且其整个发育过程可分为4个时期：零散细胞期、单层扁平细胞期、多层扁平细胞期和颗粒细胞分泌期。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。
