The invention relates to a Juglans mandshurica bark extract with good anticancer effect, which is prepared by the following steps: (1) extracting the Juglans mandshurica bark with 70-75 wt% alcohol solution under reflux for 3.5-5.5 hours, evaporating to recycle alcohol so as to obtain a concentrated solution, dissolving by adding water into the concentrated solution, and extracting with ethyl acetate to obtain an liquid extract; and (2) after drying the liquid extract, separating by silicagel column chromatography, and eluting with an eluting agent to obtain an eluate, wherein the volume ratio of chloroform to methanol solution in the eluting agent is 3:2-0:1. The Juglans mandshurica bark extract which is extracted and separated in the invention has better effect than other existing Juglans mandshurica bark extracts in the aspect of cancer resistance, especially liver cancer resistance. The extraction and separation method of the Juglans mandshurica bark extract provided by the invention is simple and easy to implement.

The invention discloses solanesyl polyamines derivatives which are compounds with the following common structural formula, wherein, n is equal to 0-2, Ar is phenyl, substitutive phenyl, 1-naphthyl, 2-naphthyl, 9-anthryl or tricyclic aryl containing N,S atoms. The preparation method is as follows: dissolve N-solanesyl-N amine alkyl piperazine in organic solvent; add aromatic aldehyde and make the mixture react for 2-24 hours under the temperature of 0-20 DEG C; steam the mixture to get rid of the solvent and then add reducer when bathing the mixture in ice water and let the mixture react for 2-12 hours under room temperature; process the products and separate the products by column chromatography to get the solanesyl polyamines derivative. The invention provides a series of new solanesyl polyamines derivatives which are the homologous derivatives of natural products, maintain the original all-trans stereo configuration of the solanesol unit and can be used as anti-neoplastic drugs and primer for the anti-neoplastic drugs. The preparation method of the invention is of simple operation with moderate condition and high reaction yield and with great market potential, thus is easy to beindustrialized.

The invention discloses a sugar-making process based on membrane clarification and multiple co-production. After the mixed juice is physically removed, it is concentrated for the first time to 18-20 o Bx, the concentrated mixed juice is then physically clarified by a ceramic membrane, and the clear juice is concentrated for the second time to 55-65 o Syrup of Bx, white granulated sugar and low sucrose liquid sugar are produced according to the conventional white granulated sugar cooking process; sugarcane raw water obtained from the first and second concentration processes is filtered by activated carbon and reverse osmosis membrane to make sugarcane plant water; ceramic membrane filtration Finally, the concentrated liquid containing impurities is clarified by centrifugation and mixed with molasses to produce brown sugar. Based on the membrane clarification process without adding chemical additives, the high-value utilization of by-products can extend the product chain and increase economic benefits. The first concentration reduces the amount of mixed juice for subsequent membrane clarification, thereby reducing membrane clarification Investment in equipment reduces production costs and greatly improves the economic benefits of sugarcane sugar-making enterprises.

The optical interface comprises a housing, a fixing buckle and an adapter. The adapter comprises a hollow metal member, an inserting core and a sleeving; the inserting core is arranged inside the metal member; a first end of the inserting core is projected out of the first end of the metal member; the sleeving is arranged on a second end of the inserting core which is opposite to the first end; the fixing buckle fixes the adapter in the housing; the first end of the inserting core and the first end of the metal member are arranged on outside of the housing; when the first end of the metal member is connected to the main body of the light transmit-receive assembly, the first end of the inserting core is received in the main body of the optical transmit-receive assembly; the sleeving sleeves the first end of the inserting core of an external optical jumper wire which projects into the housing in order to make the first end of the inserting core of the external optical jumper wire perform butt joint with the inserting core of the adapter. The optical interface of the invention is low in structure, simple in manufacture technology and low in cost, can improve production efficiency and can improve a market potential of the optical transmit-receive assembly using the optical interface. The invention also discloses an optical transmit-receive assembly.

Provided are an air conditioning unit and an operation method. The air conditioning unit comprises an evaporator (5), a compressor and a condenser (6) provided in one common totally-enclosed container (1). A first circulation channel through which the condenser (6) provides a liquid circulation working medium for the evaporator (5) is further provided at the outer side of the container (1), and the evaporator (5) can exchange heat with the outer side in an internally indirect contact heat exchange manner while evaporating the liquid circulation working medium driven by an evaporator circulating pump (7); the compressor can suck in a low temperature gas circulation working medium produced by the evaporator (5) through a gas suction end, then compresses the low temperature gas circulation working medium, and thereafter discharge a high temperature gas circulation working medium through a discharge end; and the condenser (6) can transform the high temperature gas circulation working medium into the liquid circulation working medium in an internally indirect contact heat exchange manner.

The invention relates to an unfired ferro silicon nitride-alumina composite carbon-free sliding plate and a preparation method thereof, belonging to the field of refractory materials. The sliding plate is composed of the following raw materials in percentage by weight: 55-90% of corundum, 0-20% of activated alumina, 0-30% of ferro silicon nitride and phenolic resin accounting for 2-6% of total dosage of the raw materials to serve as a binding agent. The preparation method comprises the steps of: weighing the raw materials according to the proportions, uniformly mixing the raw materials, smelting the raw materials to obtain pug, pressing forming the pug, and the drying the pug at 120-600 DEG C for 5-25hours. The product is of an oxide-non oxide composite structure and has the following excellent physical performance indexes: the apparent porosity is 3-11%, the bulk density is 3.0-3.35g / cm<3>, the normal temperature compressive strength is 100-260MPa and the high temperature flexural strength is10-50Mpa. The product provided by the invention needs no high temperature firing and oil immersion procedures, so that the production cost is greatly reduced.
