Webpage link protection method based on control character coding and steganography

The invention relates to a webpage link protection method based on control character coding and steganography. Watermark information can be embedded through selected control characters which are not displayed at a browser end, and thus link information in a webpage can be protected. First, the webpage is partitioned into blocks according to links, watermark information with any bit is generated according to all the characters of all the sub-blocks and coded into corresponding control characters to be embedded into the webpage, and a webpage with watermarks is generated; in detection, whether the link blocks are tampered or not is judged by comparing the relations between different bit numbers and thresholds of extracted watermarks and reconstructed watermarks corresponding to the link blocks; when tampered link blocks are detected, all attribute information including link addresses is deleted, and blocks are marked with warning mark information, so that a prompt is given to a user. Through the webpage link protection method based on control character coding and steganography, link block information in the webpage can be effectively protected; when the link blocks are tampered, the tampering can be detected out in time, and false information is prevented from being propagated, so that negative effects of tampered link blocks on images ad business of enterprise and public institutions are reduced.

Preparation method and application of Cs5SiFe (OH2) W11O39. 6H2O sustained and controlled release capsules

The invention relates to a preparation method of Cs5SiFe (OH2) W11O39. 6H2O sustained and controlled release capsules. The preparation method comprises the following steps of by taking Cs5SiFe (OH2) W11O39. 6H2O as a raw material and lactose, ethylcellulose, hydroxypropyl methylcellulose, silicon dioxide, montmorillonite, sodium chloride, cellulose acetate, dibutyl phthalate, dimethicone, magnesium stearate, sodium bisulfite and lauryl sodium sulfate as auxiliary materials, respectively preparing sustained-release pellets, performing wrapping with an adsorption water diversion layer, performing wrapping with a controlled-release coating layer, and finally, performing capsule filling to obtain the controlled-release capsules. According to the invention, in-vitro release is uniform, the controlled release effect can be achieved, the average release rate per 2 hours in an in-vitro release rate test is 10-15%, compared with a traditional controlled release preparation, the sustained and controlled release capsules are more uniform in release, the constant-speed release time is nearly 14 hours, the shelf life of the sustained and controlled release capsules is long and can reach 24 months, the impurity increment in the placing process is small, and the impurity increment is only 0.13% after the sustained and controlled release capsules are placed for 24 months. The sustained and controlled release capsules are high in anti-tumor activity, low in toxicity and low in price, and can be used for treating human hepatoma carcinoma cells (HepG-2), human lung cancer cells (A549), humanbreast cancer cells (MCF-7) and human colon cancer cells (CT26 and HT29).

Medicine preparation for treating malignant tumors and preparation method thereof

The invention relates to a medicine preparation for treating malignant tumors. The medicine preparation is prepared by the following steps of using ricarpa phosphate as the raw material, and adding acertain amount of filling agent, flavoring agent, adhesive, lubricant, cosolvent, antioxidant and the like; pretreating, pre-mixing, forming particles, drying, arranging particles, totally mixing, packaging and the like. The medicine preparation has the advantages that the ricarpa phosphate particle can be quickly absorbed, the effect is quickly taken, the bioavailability is high, and the carryingand taking are convenient; by adopting the special formula and special technology preparation method, the dissolving property is good, the medicine preparation can be completely dissolved within 10s,the defect of moisture absorbing and caking is overcome in the placing process, the stability is good, and the increment of impurities in the storage process is small, and is only 0.09%; the medicinepreparation is qualified in microorganism check, the shelf life is long and can reach 24 months, and the industrialized production effect is realized; after the medicine preparation is sold on market, the market blank can be filled, and the medicine preparation is suitable for being popularized and applied.

Pipeline smoke heating device

The invention discloses a pipeline smoke heating device. The heating device is fixedly into a flue, and comprises a secondary smoke channel, a gas rotational flow cavity and a center air channel fromoutside to inside. Inclined gas rotational flow blades are arranged between the outer wall of the outlet of the center air channel and the inner wall of the gas rotational flow cavity. A combustion cavity is formed in the front ends of the gas rotational flow blades and the center air channel, and a gas rotational flow cavity is formed in the rear ends of the gas rotational flow blades and the center air channel. The gas pipeline communicates with the gas rotational flow cavity, and is filled with the gas. A burning torch penetrates through outer layer walls and is inserted into the combustioncavity. A plurality layers of inclined smoke rotational blades are arranged between the outer wall of the gas rotational flow cavity and the inner wall of the secondary smoke channel. Oxygen in the smoke is adopted to complete combustion and release heat to increase the temperature of the smoke. The shape and size of flame are controlled by the rotational flow blades, and therefore the length ofthe flame is reasonable and the radius of the flame is less than the diameter of a chimney. Damage caused by superheat of the flue is avoided. The temperature rising process of the smoke is completedby the heat exchanging between cold smoke and hot smoke. The process is direct, the cost is saved, energy is saved, and efficiency is achieved.
