These observations suggest that PVA-MEC is an excellent fluorescent macromolecular material with a convenient method of preparation and had a good water-soluble ability.(2) An acrylic monomer bearing xanthene group, acryloyl-fluorescein was synthesized from fluorescein and acryloyl chloride. The photophysical behaviors of Ac-Flu and its copolymer were explored by recording the fluorescence spectra in solution, solid state and film in detail.

2我们采用基于荧光功能单体制备荧光聚合物的方法，选择荧光素为发色团，使它与丙烯酰氯反应，合成出含有双键的荧光素单体Ac-Flu，然后令其与丙烯酰胺共聚，制备得到含有荧光素生色团的水溶性荧光聚合物poly(Ac-Flu-co-AM)。

It can adaptively set the thresholds of motion selection according to the characteristics of the unplanned motion sequence.

针对在线手眼标定算法的鲁棒性，提出了一种根据运动序列的特点自动设定运动选择阈值的在线手眼标定算法。

In this paper,water-soluble ionic liquid BeS was used as extractant for sulfur compounds thiophene,2-methyl thiophene,benzothiophene,dibenzothiophene in simulated fuel and the feasible operation conditions were confirmed by extraction experiments.

选择水溶性的离子液体BeS作萃取剂，对模拟油品中的4种含硫有机物噻吩、2-甲基噻吩、苯并噻吩、二苯并噻吩进行了萃取，确定了适宜的萃取操作条件。

We introduce two pyridinedicarboxylate (2,5-H2pdc and 2,6-H2pdc) ligands, under hydrothermal or solvothermal condition, to yield 7 complexes with InCl3. Complex 17 presents a rare example of chiral binodal (4,8)-connected lattice with self-interpenetration.

选择了两种吡啶二羧酸配体： 2，5-吡啶二羧酸(2，5-H2pdc)； 2，6-吡啶二羧酸(2，6-H2pdc)和InCl3反应合成了七个配位化合物其中17表现了一例少有的手性的(4，8)连接的双节点自穿插拓扑结构。

Seveteen fine biovotine female lines also had been bred out after 5～10 generations selecting directly to the bivoltine genetic resources, which included 8 Chinese female lines, 8 Japanese female lines and 2 hybrid female lines. These female lines could be reproduced easily by asexual reproductive way, their rate of asexual developed eggs were high with only female generations and economic characters were also stability.

采取直接利用无性繁殖性状较优良的二化性现行品种资源构建雌蚕无性繁殖系的方法，经5~10代的无性繁殖继代选择，初步育成了17个雌蚕无性繁殖品系，其中中系品种8个，日系品种7个，杂交种2个。

A candidate gene could be selected because of its'biological association with some disease or being congenerous to a known gene related to the disease.

候选基因的选择可以基于与疾病间的生物学联系或是该基因与疾病某已知相关基因的同源性。

Method］twelve cases with extremities invasion bone tumor were reviewed,including 6 male and 6 female.the average age was 37.1 years old.according to the mri,typeⅰtumor located in metaphysic and growth eccentricity,and was treated with outside tumor osteotomy with reservation of one side as integumentale,the cut line was shape of "匚".type ⅱ tumor was with invasion part articular surface,and was operated with part joint osteotomy with reservation of one side as integumentale,the cut line was shape of"l".type ⅲ was with invasion total joint surface and as integmentale,all tumor segment including joint could be cut,but the shape of cut close to the diaphysis was echelonment.

方法］12例侵袭性骨肿瘤患者男6例，女6例；平均年龄37.1岁。根据mri表现选择不同截骨方法，ⅰ型肿瘤位于干骺端偏心性生长，采用保留一侧皮质骨的肿瘤外截骨，截骨线呈&匚&形。ⅱ型病例肿瘤侵蚀部分关节面，采用保留一侧皮质的部分关节截骨，截骨线呈&l&形。ⅲ型病例肿瘤侵蚀整个关节面和骨皮质，可切除包括关节在内的整个瘤段骨，只是近骨干侧截骨呈阶梯状。

RHR divides the whole network into many homocentric rings, and maintains many energy sufficient route paths between neighboring rings; the regular update of key nodes leads to more balanceable energy consumption; every node has many key nodes for transmission, which increase the robustness.

RHR将网络划分为多个同心环，并在环与环之间维护多条能量有效的多跳路径；对关键节点的有序轮换使能耗更加均衡；每个节点可选择多个关键节点，增强了协议的稳健性。
