    • A method for enhancing heterogeneous asymmetric selectivity and catalytic activity belongs to the field of catalytic asymmetric organic synthesis technology, the preparation method of the invention are as follows: firstly preparing the chiral L-amino acids intercalated LDHs by coprecipitation or ion-exchange method; exfoliating the chiral L-amino acids intercalated LDHs into dispersed system of chiral L-amino acids attached to the inorganic LDH nanosheets; then coordinating the L-amino acids in the above dispersed systems with the metal centers for different types of asymmetric catalytic reactions. The results show that the as-prepared catalyst can enhance the asymmetric selectivity effectively. Compared with the homogeneous counterparts under the same reaction conditions, the catalyst exhibits relatively higher yields and largely improves the selectivity of the asymmetric reaction products; and thus the chiral compounds with a higher optical purity can be obtained.
    • 一种增强非均相不对称选择性和催化活性的方法属于催化不对称有机合成技术领域,本发明的制备方法如下:首先通过共沉淀或离子交换法制备手性L-氨基酸插层的LDHs; 将手性L-氨基酸插入的LDH分解成附着于无机LDH纳米片的手性L-氨基酸的分散体系; 然后将上述分散系统中的L-氨基酸与用于不同类型的不对称催化反应的金属中心配位。 结果表明,所制备的催化剂可有效提高不对称选择性。 与相同反应条件下的同质物相比,催化剂的产率相对较高,大大提高了不对称反应产物的选择性; 因此可以获得具有更高光学纯度的手性化合物。

    • A counting method pre-establishes a user equipment information record and a user number threshold in a cell. The method includes: A. informing UEs in the cell where multimedia broadcast and multicast service is transmitted about the beginning of the counting, receiving a response from the UEs, and recording the responded UE records into the UE information record; B. monitoring the cell, and updating the UE information record when determining that a UE having a varied communication behavior in the cell; C. according to the UE number in the UE information record and the user number threshold in the cell, determining whether to trigger a re-counting or not, and if yes, returning to Step A; otherwise, returning to Step B. A network control device includes a storage module, a control module, and a communication module. Through the technical solution, the accuracy for determining the MBMS operation transmission mode at the network side is improved.
    • 计数方法在单元中预先建立用户设备信息记录和用户号码阈值。 该方法包括:通知在小区内的多媒体广播和多播服务关于计数开始发送的UE,从UE接收响应,并将响应的UE记录记录在UE信息记录中; B.监视小区,以及当确定在小区中具有变化的通信行为的UE时,更新UE信息记录; C.根据UE信息记录中的UE号码和小区中的用户号码阈值,确定是否触发重新计数,如果是,返回到步骤A; 否则返回到步骤B.网络控制装置包括存储模块,控制模块和通信模块。 通过技术方案,提高了确定网络侧MBMS操作传输模式的准确性。

    • A head includes first and second read modules. The first module has an MR element formed on a wafer having a grating directed along a first direction. The magnetization of the first module element is directed along the first direction. The first module element is biased with a first current directed along a direction such that magnetically stable operation of the element results, that is along an opposite second direction. The second module has an element formed on a wafer having a grating directed along the first direction. The second module is flipped respect to the first module such that the grating is directed along the second direction. The magnetization of the second module element is directed along the second direction. The second module element is biased with a second current directed along the direction opposite to the first current, i.e., the second current is directed along the first direction.
