1. I don't understand the data above... I've been working as a battery for five years... The capacity of all batteries will drop every winter or when the temperature is low (20-30%). If it exceeds this data, it's abnormal, but your battery has exceeded one year... Generally, electric vehicle batteries don't need water in two years, unless they are often overcharged. So you don't have to maintain or add water to use now... You just need to keep the battery full now... Don't charge every time you run out of electricity... Wait until next summer to see the situation... If it's not easy to use next summer (because summer is the time when the battery performance reaches its peak)... Then it's suggested that you change a battery... Or take it to a professional place to repair the battery It has the value of repairing... And it should be reminded that you should remember not to overcharge now... This is related to whether your charger is good or not... If you find that the charger will not jump the light or will soon jump the light... Generally, there is a problem with the battery, and the charger may be unstable
2. E-cigarette only contains a small amount of nicotine, but it still has smoke. It just plays a relatively auxiliary role. The real effect of quitting smoking is not big. Smoking certainly can't stop smoking. Quitting smoking depends on personal willpower. Anyway, I haven't seen success in quitting smoking with this. If you want to quit, you should make up your mind and get through the psychological period.
3. There is no such word, only bird, which means bird
birds are also called birds. Definition: feathered oviparous vertebrates. Dictionary explanation: a class of vertebrates, which are warm blooded, oviparous, breathing with lungs, almost full body feathered, hind limbs able to walk, forelimbs turned into wings, most of them able to fly. In zoology, the main characteristics of birds are: streamlined body (spindle or shuttle), most of the flying life. The body surface is covered with feathers, and the forelimbs generally become wings (some species have degenerated wings); The chest muscle is developed; Short rectum, large food intake, fast digestion, that is developed digestive system, help to rece weight, concive to flight; The heart has two atria and two ventricles, and the number of heart beats is fast. The temperature is constant. In addition to the lungs, the respiratory organs also have air sacs formed by the protruding walls of the lungs, which are used to help the lungs carry out double breathing
feathers can be divided into three types: normal feather, downy feather and hairy feather. On both sides of the plume branch of the normal feather, there are dense barbules, on which there are hooks or grooves, and the adjacent barbules are connected with each other to form a flat and elastic feather. The front feathers on the body surface form a windproof shell and streamline the bird. The right feather on the wing and tail plays a decisive role in flight and balance. The structural characteristics of downy feather are that the feather axis is weak and the hook like protrusion of the feather branchlets is undeveloped, so it can not form a solid feather and has the function of heat preservation. Duck down is the feather of a ck. The hairiness is very fine and hairy. It grows in the normal feather and down feather, and can be seen only after the normal feather and down feather are removed
there are no sweat glands in the skin of birds, and the only sebaceous gland is the tail gland. The oil secreted by the tail gland is smeared on the feather by the beak to make the feather moist and not wet. The secretion of the tail finger gland also contains ergosterol, which can be converted into vitamin D under ultraviolet radiation. When birds rub their feathers with their beaks, vitamin D can be absorbed by the skin, which is concive to the growth of bones
birds are adapted to flying life. Their bones are light and strong, thin, long and hollow with air sacs. Many pieces of bone are joined together to increase firmness. The spine can be divided into five parts: cervical spine, thoracic spine, lumbar spine, sacral spine and caudal spine. The number of cervical vertebrae is large, and the vertebral body is saddle shaped, which makes the neck very flexible (the head movement of owl can reach 270 °)
the last thoracic vertebrae, all lumbar vertebrae, sacral vertebrae and part of caudal vertebrae are completely healed together, which is called the comprehensive sacral bone, which is the strong pillar of the waist. There are hook like processes on the ribs, which hook each other to make the chest more solid
the forelimb turns into a wing, the bones line up in a straight line, there are active joints between the bones, and the carpal bone, metacarpal bone, and phalangeal bone at the end heal and deform, making the wing become a whole when flapping. The shoulder belt is composed of scapula, black beak and clavicle. The thin and elastic clavicle is in a "V" shape, which can hinder the convergence of the left and right aconions when the wings are bulging, and can also enhance the elasticity of the shoulder strap
the whole body weight of birds falls on the hind limbs, and the hind limb bones are strong. Compared with the hind limb bones of other terrestrial vertebrates, the tarsal bones of birds extend to increase elasticity. Birds usually have four toes. In alt birds, the iliac bone, Ischia bone, pubic bone and sacrum of the belt are integrated into a whole, which increases the firmness of the belt
in birds, the pectoral muscles related to flight are particularly developed, accounting for about 1 / 5 of the body mass. It can send out strong power and pull the wings to flap. And back muscle degeneration, which is the opposite of fish
the pectoral muscles of birds can be divided into two types: large pectoral muscles and small pectoral muscles. The former starts from the keel process and ends at the ventral surface of the humerus; The latter starts from the keel process and passes through the three bony foramen composed of clavicle, coracoid and scapula with long tendons, and ends at the back of proximal humerus. When contracting, the wings are lifted up
the muscles of the hind limbs are concentrated in the upper part of the thigh and connected to the toes with long tendons. In this way, the muscles controlling the movement of the forelimbs and hind limbs are concentrated in the center of the body, which is of great significance for maintaining the stability of the body's center of gravity when flying
modern birds lack teeth, and the masticatory function is replaced by sandbags. During the reproctive period of female pigeons, the crop wall can secrete "pigeon milk" to feed the young pigeons. The digestive glands (liver and pancreas) of birds are very developed. They secrete bile and pancreatic juice respectively and inject them into the odenum to participate in the digestion of the small intestine. Pigeons have no gallbladders, while most birds such as chickens and cks have gallbladders. Birds have strong digestion ability and eat a large amount of food without starvation, which is related to the high energy consumption of birds when flying
the brain, cerebellum and midbrain of birds are well developed. The cerebral hemisphere is larger, which is mainly e to the enlargement of the striatum at the bottom of the brain. In birds, the striatum is a high-level part of movement management, which is also related to some complex life habits. The results showed that after removing part of the striatum of pigeons, the normal excitation and inhibition of pigeons were destroyed, the vision was affected, and the habits of courtship and nesting were lost. In birds, the cerebral cortex is not well developed and the cerebellum is well developed, which is related to the coordination and balance of flight movement. The midbrain forms a pair of well-developed optic lobes on the back
among the sensory organs of birds, the most developed is the visual organ which plays an important role in flight, while the olfactory organ is not developed. Depending on the developed ciliary muscles, bird eyes can quickly adjust their vision and change from hyperopia to myopia. Therefore, when the bird flies fast in the tree, it never touches the branch; Or when diving from high altitude to the ground for food, it can also change from "hyperopia" to "myopia" in a moment. The blink membrane of bird's eye is developed, which can cover the eyeball ring flight and play a protective role
the kidneys of birds are very large, accounting for more than 2% of the body weight, even more than that of mammals. The development of kidney is related to the metabolism of birds. Birds have no bladder, less water in the urine, white thick paste, with the fecal discharge and do not urinate alone
pigeons, like most birds, have no external connector (ostrich, ck and goose have connector). When they mate, the cloacal foramen of male and female pigeons contact each other, and the semen enters the female body for internal fertilization. After the egg matures, it breaks the ovarian wall and comes out, and is inhaled into the trumpet mouth of the fallopian tube. If there is sperm, it is fertilized here. Whether the egg is fertilized or not, when it goes down the fallopian tube, it is coated with protein, then the eggshell membrane is added, and finally the calcareous eggshell is added to the uterus. The incubation period of fertilized eggs is about 16 days for pigeon, 21 days for chicken and 28 days for ck
IR is a combination of vowels in English. In a single word, it is a long vowel / & "605"/ When pronouncing, the tip of the tongue must leave the lower teeth and roll up the gums as far as possible. The middle part of the tongue bulges, and the tongue position is close to half height. It is the highest one of the three middle vowels. The gums are close to half closed, and it is the smallest one among the three middle vowels. The lips are slightly flat, and they are pulled away to the left and right sides, showing a smile. This sound appears at the beginning, middle and end of the word, For example:
birthday
circle circus
dirty
bird
circle circle
dirty st
girl
I hope I can help you solve your doubts.
