分离性

The motion of two charged quasiparticle s on an infinite Chain in a uniform electric field is presented.

本文研究了在均匀电场中位于一维长链上的两带电准粒子的运动，给出了一般情况下的精确解，并讨论了两准粒子运动的动态定域性和复合、分离等问题。

Therefore, the patents at issues directed to 'isolated DNA' containing sequences found in nature are unsustainable as a matter of law and are deemed unpatentable subject matter.

因此，讼争的专利不能得到法律的支持，故认为其没有专利性。因为，该专利所指向的被分离的DNA包含了自然状态下就已存在的DNA序列。

Objective To explore the situation of Mh infection and drug resistance of female non-gonococcal urethritis patients in our country.

利用Mh的分离、鉴别、定量和药敏试剂盒，对我国上海、四川、广西、浙江、新疆五地区妇女非淋菌性尿道炎患者的Mh感染与药敏进行测定。

Objective To study the method of isolation and cultivation of neural stem cells from newborn rat spinal cords and identification of its differentiation,to establish cytological foundation for vicariousness therapy of peripheral nerveous system diseases by using spinal stem cells.

目的：探讨分离、培养新生大鼠脊髓源性神经干细胞的方法并对其进行分化鉴定，为临床应用脊髓神经干细胞进行周围神经系统疾病的替代治疗奠定细胞学基础。

Sample collection: Two hundred and fifteen sera samples of normal population were collected from the peripheral blood of healthy blood donors of Shenyang, and the sera were separated by centrifugation after blood clotting; The patients sera were collected from the outpatients and inpatients of No. 1 hospital of China Medical University and the Second hospital of Jilin University. Syphilis was confirmed by clinical and serum test of TPHA and RPR; That of pemphigus vulgarism was confirmed not only by clinical, histopathological examination, but also by direct and indirect immunofluorescence test. DIF test on lesion or non-lesion skin showed immunoglobin and/or C3 deposits in the intercellular space of epidermis, and IIF test showed positive anti- intercellular antibody in patient serum using mouse's or rat's tongue or esophagus as substrate.

标本的收集：正常人的血清：采集沈阳市正常献血员外周静脉血共215份，待血凝后离心分离血清；患者的血清：来自中国医科大学一院及吉林大学二院门诊及住院部的病人，梅毒患者除了病史及临床表现外，全部经血清学TPHA及RPR确认；寻常性天疱疮患者除了临床及组织病理诊断外，还进行了直间接免疫荧光的检测，直接免诊断疫荧光：在皮损区及非皮损区的表皮细胞间显示IgG和/或C3补体沉积；间接免疫荧光用鼠或兔的舌或食管作为底物，在病人的血清中显示有肯定的细胞间抗体。

As a matter of fact, the viruses of highly pathogenic bird flu do widely spread all over the wildfowl of nature and live together with wildfowl in peace for a long time.

事实是这样的：高致病性禽流感病毒的确广泛存在于自然界的野禽中，与野禽长期和平共处。100多年前，人们开始认识禽流感病毒；50多年前，分离出了H5N1病毒。

Finally the new line of fruit fly with 3 recessive characters (white-eye, winglet and ebony-body) was purified.

以得到的白眼、小翅、黑檀体三隐性新品系为材料，可同时满足三大遗传规律（分离规律、自由组合规律、连锁遗传规律）和性连锁遗传等实验教学的需要。

In order to obtain a nonlinear dynamic control law which has global stability,the "workless force" is abstracted to simplify the induction motor control using the passivity theory.

为了实现异步电机转速的全局稳定非线性动态控制，应用无源性理论从能量的角度分析异步电机，从中分离出不必抵消的"无功力"，简化了异步电机的控制，并据此导出一个全局稳定的非线性动态输出反馈控制律。

Swine influenza is caused by swine influenza virus, and it can induce an acute zymotic disease of respiratory tract. There were related reports about the outbreak of SI when the "Spanish" influenza was being in the USA, but until the late 1920s there was first SIV isolated from pigs.

猪流感(Swine Influenza，SI)是由猪流感病毒(Swine Influenza virus，SIV)引起猪的一种急性、高度接触性的呼吸道传染病。1918年美国首次报道了SI的爆发，而直到二十世纪二十年代末才从猪体中分离到第一株SIV。

So the model warehouse is improved succinctly and continuously developed. Therefore, it has accessional value for the field interrelated with simulation research of virtual experiment.

系统模型实体与控制相分离的结构大大提高了建模的效率和准确性，并增强了虚拟器件的独立性和可复用性，使模型库更简洁并易于完善，对相关仿真领域的研究有较高的参考价值。
