The micro circulation is by blood, the lymph and tissue fluid flowing which directly participates in the organization, the cell matter, the energy, the information transmission . May directly observe the blood flows in the thin artery, the blood capillary, and the thin vein through the micro circulation microscope , but if it does not do the special handling is that cannot see clearly the lymph and tissue fluid mobile, therefore, on clinical usually thought the micro circulation refers to the blood micro circulation in the blood capillary. Directly the blood, the lymph, tissue fluid flowing which participating in the matter, the information, the energy transmission of organization, and the cell , is called the micro circulation.
The Nailfold Capillaroscopy Microcirculation Microscope is an advance medical photoelectric apparatus,equipped with built in special LED light source,used mainly in observation on human nail fold capillary microcirculation or term as video Nailfold capillaroscopy,Such as capillary blood flow, abnormal microcirculation of the vascular structure, cell adhesion, through its powerful optical magnification. Undistorted, real time dynamic video streaming via Sony CCD imaging device onto the LCD monitor screen.

Simply insert the finger to the holder below the optical lens apparatus, fine-tune to fix the focal length and uncover the desired images within seconds.Blood capilliary microcirculation microscope is a non-invasive diagnostic tools, which is gaining large credit among physicians of different specialities in for study of skin blood capilliary network.
Causes of crop damage and preventive remedies
Improper or excessive application of chemical fertilizers to crops often leads to gluttony, leggy, late maturity, weakened resistance, lodging, disease and insect pests, or burning of seedlings and wilting of crops. Light crops result in reduced yields and the entire plant is dead. This undesirable phenomenon caused by chemical fertilizers is called "fat harm." There are three main causes of fertilizer damage in production: First, water loss. If one application of excessive fertilizer or soil moisture after fertilization is insufficient, resulting in excessive concentration of soil fertilizer solution, the water within the crop cell reverse osmosis, resulting in crop water loss, wilting, affecting normal development and death; second, burns. Some fertilizers, such as ammonium bicarbonate, are used when the temperature is relatively high. It is easy to produce a large amount of ammonium gas, burn the leaves and roots of the crops, light the lower tips of the leaves to yellow, in serious cases the whole plant withers, and the third is poison. Excessively surpassing the demand of a crop for a certain element of fertilization will produce poison to the crop, resulting in poor growth and reduced yield. In addition, some fertilizers, such as lime nitrogen, can be converted and decomposed in the soil to produce toxic substances if they are applied directly, poisoning crop roots, causing crop damage and even death. According to the reasons of fertilizer damage, when applying chemical fertilizers, we must master the abundance of soil nutrients and the demand for nutrient elements of crops. We must conduct scientific and rational fertilization and must not increase the amount of fertilizers. Generally, heavy weight light fertilizer is adopted, and the amount of topdressing can not be too much, and the method of application should be paid attention to to prevent injury. After the occurrence of fertilizer damage, the causes should be analyzed in a timely manner and targeted remedial measures should be taken. If the wheat is applied with too much nitrogen, the wheat seedlings will have many phenomena such as many yellow leaves and small tillers. Phosphorus and potassium fertilizers should be added. After every 667m 2 is soaked with 50kg of water and 1kg of superphosphate for 24 hours, take it for 24 hours. The clear liquid was evenly sprayed on sunny afternoons, and 50--100 kg of plant ash were applied every 667 m2. In addition, prior to jointing, plant growth regulators such as paclobutrazol or chlormequat may be sprayed in accordance with the concentration requirements to inhibit the growth of the stems of the wheat seedlings, promote the development of the root system, and effectively alleviate or reduce the damage.
