The pool-integrated equipment is one of the main products in the modern pool industry market. The pool integrated equipment with its technical content, its design concept, brainstorm to give the pool equipment market a new impact. Pool-integrated equipment is a pool equipment that integrates pool filtration, sterilization and recycling. It has become a mainstream product in the current market of pool equipment
Signs of birth. Since the middle of the 20th century, technology has grown faster and faster. It was only six and a half years since the discovery of uranium fission in January 1939 to the first atomic bomb exploded in July 1945. The emergence of electronic computers has led to more profound changes in the fields of human social life. These technological breakthroughs can be called technological revolutions
1, if the temperature is below 38.5 ℃, or associated with headache, nausea and other symptoms commonly, need not special treatment, or baby do physical cooling, generally after physical cooling, the baby's body temperature returned to normal, headache, nausea will disappear or ease.
The event takes place in English Bay at 10:00 PDT on four nights, beginning over a Wednesday and ending over a Saturday, on the 2 week period during July and August.

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
