摘要：【中文】提供一种喜树碱衍生物及其在制备抗肿瘤药物中的用途，具有下述通式(I)：MTT实验表明该喜树碱衍生物在ROS条件下才具有细胞毒性，在不含ROS的培养液中细胞毒性较小。由于肿瘤组织中ROS浓度较高，因此该喜树碱衍生物制备的抗肿瘤药物具有毒性较小特点。 【EN】Provides a camptothecin derivative and application thereof in preparing antitumor drugs, and the camptothecin derivative has the following general formula (I): MTT experiments show that the camptothecin derivative has cytotoxicity only under the condition of ROS, and has low cytotoxicity in a culture solution without ROS. Because the ROS concentration in the tumor tissue is higher, the antitumor drug prepared from the camptothecin derivative has the characteristic of lower toxicity.

摘要：【中文】本发明涉及一种三相导体转换接头，包括密封筒体和安装在密封筒体两端的密封法兰，两密封法兰上分别水平布置和竖向布置三个转接嵌件，密封筒体中设有三相导体，其中处于两侧的导体包括弯折段，两侧导体的弯折段关于中间导体中心对称，三相导体的两侧端部由于弯折段而分别呈水平一字形和竖直一字形用于连接两密封法兰上对应的转接嵌件。使用时，三相导体转换接头能转换气体绝缘金属封闭开关设备的三相导体的一字形布置方式，且在需要向一字形延伸方向换向走线时，能先改变一字形布置方式，将走线改为向垂直一字形方向换向走线，避免导体之间干扰；将两组三相导体转换接头对接在一起后，能够在不改变一字形布置方式的基础上实现相序的互换。 【EN】The invention relates to a three-phase conductor adapter, which comprises a sealing cylinder and sealing flanges arranged at two ends of the sealing cylinder, wherein three adapter inserts are respectively horizontally and vertically arranged on the two sealing flanges, a three-phase conductor is arranged in the sealing cylinder, the conductors at two sides comprise bent sections, the bent sections of the conductors at two sides are symmetrical about the center of a middle conductor, and the end parts at two sides of the three-phase conductor are respectively in a horizontal line shape and a vertical line shape due to the bent sections and are used for connecting the corresponding adapter inserts on the two sealing flanges. When the three-phase conductor adapter is used, the in-line arrangement mode of three-phase conductors of the gas insulated metal-enclosed switchgear can be converted by the three-phase conductor adapter, and when the routing needs to be reversed towards the in-line extending direction, the in-line arrangement mode can be changed firstly, the routing is changed into the direction perpendicular to the in-line direction, and the interference between the conductors is avoided; after the two groups of three-phase conductor conversion connectors are butted together, the phase sequence interchange can be realized on the basis of not changing the linear arrangement mode.

摘要：【中文】本发明提供了一种移动式发电系统及其燃气轮机发电车，燃气轮机发电车包括：底盘、车厢、发电机、燃气轮机；车厢上还设置有进风口和出风口，所述进风口用于与燃气轮机的进气端相通，出风口用于与燃气轮机的出气端相通；进风口和出风口的口沿均可拆连接有风筒，风筒用于与燃气轮机的进气端或出气端连通。将与进风口、出风口适配的风筒可拆连接在车厢上，风筒不会占用车厢内空间，从而使车厢具有足够的空间来安装大功率的燃气轮机机组；在燃气轮机发电车到达现场后，操作人员可以再将风筒安装在车厢上，不影响燃气轮机及发电机的正常运行，而在运输途中，风筒从车厢上拆下，使燃气轮机发电车满足道路运输规定中关于高度、宽度的要求。 【EN】The invention provides a mobile power generation system and a gas turbine power generation vehicle thereof, wherein the gas turbine power generation vehicle comprises: a chassis, a carriage, a generator and a gas turbine; the carriage is also provided with an air inlet and an air outlet, the air inlet is communicated with the air inlet end of the gas turbine, and the air outlet is communicated with the air outlet end of the gas turbine; the air inlet and the air outlet are detachably connected with an air duct which is communicated with the air inlet end or the air outlet end of the gas turbine. The air duct matched with the air inlet and the air outlet is detachably connected to the carriage, and the air duct does not occupy the space in the carriage, so that the carriage has enough space for installing a high-power gas turbine unit; after the gas turbine power generation vehicle arrives at the site, an operator can install the air duct on the carriage, the normal operation of the gas turbine and the generator is not affected, and the air duct is detached from the carriage in the transportation process, so that the gas turbine power generation vehicle meets the requirements of road transportation regulations on height and width.
