If you believe you could be in danger, consider these safe home security camera:
When autumn comes, the baby is prone to diarrhea. Diarrhoea caused by rotavirus accounts for about 70 to 80% of childhood diarrhea in autumn and winter. It just like other viruses, are not afraid of antibiotics, use of antibiotics would only backfire and abuse will not only destroy bacteria in the intestinal tract normal, dysbacteriosis, affect the intestinal absorption function, and bacteria resistant strains growing, can also be a secondary mould enteritis, etc., make or aggravate diarrhea in delay. For the diarrhea caused by rotavirus, the majority of children can recover as long as the rehydration solution is selected and the microecological modifier and mucosal protection agent are selected. Even if it is not caused by rotavirus infection, it is not effective to use antibiotics for the non-infective infantile diarrhea caused by inappropriate diet and climate mutation.

Space probe according to the detection of object is divided into lunar probe, probe and interplanetary spacecraft, small body such as a space probe to leave the speed of the earth must be large enough to overcome or get rid of the earth's gravity, realize the deep space flight. The probe orbits the heliocentric elliptical orbit (double-cut orbit) that is tangent to the earth's orbit and the planet's orbit, and may meet the target planet; Increase speed to change the orbit, flew to target the planet can shorten the time in order to ensure the detector fly the double track to the planetary orbits and tangent with the target when the target planets also run to it, must be chosen in the earth and the target planet at a particular moment of relative position detector. Detector can fly around the star, the use of planetary gravitational fields accelerate continuous multiple planets orbit the significant characteristic of space probe is, flying in space for long time, the ground cannot real-time remote control, so must have the ability of autonomous navigation; To fly outside the solar system, away from the sun, solar arrays, and nuclear energy systems; It is necessary to adopt special protective structure to withstand very severe space environment. Landing or walking on the surface of the moon or planet requires some special form of structure
