The powdery material sampling device comprisesa barrel body and a barrel cover, wherein the barrel body is connected with the barrel cover in a sealing manner; the inner part of the barrel body is provided with a separation board; an internal space of the barrel body is separated into a powder accommodation cavity and a liquid accommodation cavity by the separation board; the separation board is provided with a through hole; the barrel coveris provided with a feeding opening; the feeding opening is communicated with the powder accommodation cavity; the liquid accommodation cavity is used for holding liquid; the liquid accommodation cavity is internally provided with a guide pipe and a defoaming net; the guide pipe is provided with a first end and a second end; the first end is positioned above the liquid level of liquid and is communicated with the through hole; the second end is positioned below the liquid level; the defoaming net sleeves the guide pipe and is positioned below the liquid level. The powdery material sampling device provided by the invention can effectively relieve the production of dust, so as to reduce hazards to a human body and environment; meanwhile, a sample is conveniently stored during detection and further the sample is effectively prevented from being damped.

The invention provides a method for taking a physical property fault analysis test piece of a semiconductor device. According to the method for taking the physical property fault analysis test piece of the semiconductor device, a half sawing step is sequentially executed from one side edge to a first narrowing edge of a piece taking area and from a second narrowing edge to the other side edge of the piece taking area, so that the taking-out test piece with a convex section is formed. Therefore, the obtained boundary of the taken-out test piece can reach the target position more easily, the FIBthinning time can be shortened, byproducts generated during FIB thinning can be relieved, a sample can be reworked, and thus the flexibility of sample preparation is improved.

The invention provides a traditional Chinese medicine composition of eczema ointment and a preparation process of the traditional Chinese medicine composition, and relates to the technical field of traditional Chinese medicines. The traditional Chinese medicine composition of the eczema ointment comprises the following components in parts by weight: purslane, artemisia annua, pepper, mint, felwort, fructus cnidii, radix sophorae flavescentis, paniculate swallowwort root, chrysanthemum, coptis chinensis, golden cypress, honeysuckle, sanguisorba officinalis, lithospermum erythrorhizon and dandelion. The traditional Chinese medicine composition of the eczema ointment has mild drug properties, has small irritation to human skin, has a good eczema treatment effect on a patient, has a good itching and pain treatment effect, and avoids secondary infection and other conditions caused by scratching of the patient. In addition, the invention further provides the preparation process of the traditional Chinese medicine composition of the eczema ointment; effective components of all the components in the composition are fully extracted through a reflux extraction method; the external ointment is prepared; and the treatment effect on eczema can be improved.

The invention relates to an efficient rotary disc welding wax die. The efficient rotary disc welding wax die comprises a base. The base is provided with a supporting column. A spark collector is arranged in the supporting column. A rotation shaft is arranged on the top of the supporting column and sleeved with a rotary disc through a connecting piece, the rotary disc can be detached, the surface of the rotary disc is electroplated with JR-CM fire-resistant diamond, and the rotary disc is provided with a hole with the diameter being 0.1 mm to be connected with the spark collector. A power device is arranged on the right side of the spark collector and connected with the rotation shaft. The efficient rotary disc welding wax die is simple in structure and good in heat resistant effect and can bear the temperature ranging from 1,500 DEG C to 2,000 DEG C, the spark collector is adopted and can effectively relieve sparks generated during work, the sparks are converted into electric power in time, energy is saved, cost is reduced, the work efficiency is improved, and the stability and safety of the structure are guaranteed; rotating and grinding are conducted at the same time, grinding is uniform, the surface smoothness is high, an oil cylinder nozzle is adopted, a corresponding gear rotates, stable running of the gear is guaranteed, and the service life is prolonged.

The invention relates to the field of combustion and environmental protection and in particular relates to a carbon dioxide and oxygen gas mixing device and a mixed gas combustion-supported polluted gas zero emission system. As gas participating combustion-support is oxygen and carbon dioxide mixed gas, oxygen participates combustion to generate carbon dioxide during full combustion, so that the content of carbon dioxide in tail gas is considerably high: 95% or above. Therefore, the recovery difficulty of carbon dioxide can be extremely reduced, and the cost of recovering carbon dioxide is also lowered, emission of carbon dioxide can be further extremely reduced, atmospheric pollution is reduced, and generation of greenhouse effect is alleviated; meanwhile, as participating combustion-support is oxygen and carbon dioxide mixed gas, massive nitrogen participating combustion is also avoided, so that emission of nitric oxides is avoided, and therefore, the atmospheric pollution is reduced, and moreover, generation of haze is also alleviated, and the combustion heat efficiency is increased.

An embodiment of the present invention provides a lithium negative electrode pretreatment protective agent, the lithium negative electrode pretreatment protective agent includes a compound containing a sulfonyl fluoride structure represented by formula (1), wherein R is an n-valent hydrocarbon group, a substituted hydrocarbon group or Hydrocarbyloxy group, n is an integer of 1-3; the sulfur atom in the sulfonyl fluoride structure is connected with the carbon atom in the hydrocarbyl group, the substituted hydrocarbyl group or with the oxygen atom in the hydrocarbyloxy group. Using the pretreatment protective agent to pretreat the lithium negative electrode can form a protective layer rich in lithium fluoride and sulfur-containing compounds in situ on the surface of the lithium negative electrode, thereby effectively stabilizing the lithium negative electrode, reducing side reactions and alleviating lithium dendrites. produced to improve the coulombic efficiency and safety of lithium batteries. Embodiments of the present invention also provide a lithium negative electrode pretreatment protection method and a lithium negative electrode with a protective layer.
