1. Since the problem of composition uniformity is involved, the system involved is probably binary or multicomponent solid solution system; The temperature range of cooling process generally refers to the temperature from above the melting point to the point where the components in the solid solution do not diffuse

there are two key problems, one is whether the temperature of each part of the melt is consistent ring solidification; The other is whether the so-called slow cooling is "slow enough.". Many reasons are omitted here...

to start with quick cooling, which is relatively simple. In the process of rapid cooling, a large number of melt nucleation occurs rapidly. Due to the excessive cooling rate and deviation from the thermodynamic equilibrium state, the formed solid phase composition follows a more convenient process (kinetic requirements), that is, the composition of the solid core is the composition of the liquid phase, and there is no segregation. That's the so-called composition uniformity. However, if it is impossible to ensure that the temperature of each part of the melt is consistent ring the cooling process (the actual situation is often the case), it is another matter

moreover, slow cooling is also simple if it is infinitely close to the state of thermodynamic equilibrium. According to the phase diagram (e.g. BiSb alloy), although the composition of the primary crystal core formed ring solidification is different from that of the liquid phase, the elements in the solid phase have enough time to diffuse, so the homogeneous alloy with the same composition can be obtained at last. However, the actual situation is not so, relative to the diffusion rate in the liquid phase, the diffusion coefficient of atoms in the solid phase is very small, normal furnace cooling rate, it can be considered that the atoms in the solid phase hardly move In other words, it is difficult to obtain the alloy with uniform composition under normal slow cooling. As for the specific reasons, it still depends on the phase diagram

say something else

assuming the simplest one-dimensional directional solidification process and the simplest binary infinite solid solution alloy (such as BiSb), slow cooling (slow cooling) starts from one end of the melt, and the solid phase in equilibrium with the liquid phase is solidified first at this end (the latter is precipitation). According to the phase diagram, the composition of the first solid phase is bound to be different from that of the liquid phase. With the solidification process from one end to the other end, one-dimensional crystal rod will be formed. The composition at both ends deviates from the nominal composition, and the middle part of the crystal rod is relatively consistent with the design composition distribution

solidification process in the casting mold: if the cooling is slow, then the tube wall is the first to cool and nucleate, and the cooling is the slowest in the most central part; Compared with the one-dimensional directional solidification process, there will be a certain composition deviation from the surface to the center of the ingot.

2. There's a mistake on the first floor. It's not the exhibition center in Houjie, it's the exhibition center in the administrative center. How did the bus to humen get there? Get out from Dongguan east railway station, cross the overpass to the opposite bus station, take K18 (the fastest) or 303 bus to Nancheng station, turn No.27 city bus at Nancheng station, get off at the east of convention and Exhibition Center, get off and go back, then turn right at the intersection
K18 is the fastest way to take the East Express route. The nearest station to the Convention and Exhibition Center is Nancheng station. There are only six stops from Nancheng station to the east of the Convention and Exhibition Center, and No.27 bus will arrive in more than ten minutes. If there is no delay on the road and you can get to the train quickly, it will take no more than two hours from the east railway station to the exhibition center, which is estimated to be about one and a half hours.

3. 1. Cats planet cat theme park
there are many pets cafe in Causeway Bay. Why do you call it an "extraordinary cat shop"? Let's talk about the general cat shop first - cats and cats are locked in cages, and the transparent glass blocks the distance between people and cats. When you meet a lovely cat, you can only hope but not touch it. Disappointed, right
the planet meow in Causeway Bay allows you to get close to cats. Fourteen cats walk around freely in the store. There is a special person to explain the cat's character to you. There are all kinds of high-quality procts and postcards on sale in the store. You can buy them as a gift and see the cat
pay attention! Only drinks are available here. Although you can bring your own food or take out, in order to focus on playing with cats, Xiaobian still suggests that you eat in other places first, and then come back when you are full
2. Meizi cat house
the Meizi cat house hidden in the instrial building, although the shop is small, it is carefully arranged and decorated with many cats. All the pictures on the wall are inseparable from cats
there are many "cat PR" guests in the venue, and cats are very lively. They will come to you at any time, or they may hide and enjoy the "two cat world". The store also provides toys for customers to tease the cat. When the cat doesn't come down, the owner will lead the cats out to play with us
when you are a little hungry, you can order an egg bun. The rice mpling with curry sauce is smooth and tender. The shop assistant is also very careful. He will know the taste of each guest when ordering, and how spicy the curry is. More or less spicy is OK. Desserts also have many styles. Cakes and woodchaff pudding are also made at home. In terms of drinks, lafua coffee and hot drinks with cat meat ball soft candy series made by the store are also worth recommending to you. Seats are limited. Please make a reservation first
3. Just fun club
mikiki in San Po Kong is one of the few shopping malls in Hong Kong where people and dogs can walk together (remember to rent a pet car). Here is a pet restaurant, "just fun club", which specializes in a variety of home-made health food without additives
in front of the refrigerator, you can see birthday cake, beef in mini steamer, hot dog, hamburger, French fries, egg tart, meat tart, potato cake... WOW! At first glance, I really think it's human food. In fact, it's all for pets. It shows the delicacy of appearance! Many styles, should be able to meet the picky pet
there are many colorful tables in the restaurant, and there is still room for pets to move. The lamp on the ceiling is made of dog bones and footprints. Its appearance is very interesting. In addition to the restaurant, there are also spa, beauty shower services, all kinds of pet procts for sale, and you can enjoy free delivery service if you buy more than $300. Even if you don't have a pet, it doesn't matter. You can play with the dogs and cats in the field
4. Six degrees Cafe
next stop, Xiaobian will bring you to Yuen Long! The first anniversary of six degrees cafe, formerly known as a village house with a long history. After renovation, more or less retain the rural style, outside the fence with swing, plant, green. After changing the orange on the house, the whole feeling became lively and vivid immediately
there is an open-air teahouse in the coffee shop, where guests can watch dogs playing outdoors while eating delicious food or barbecue (appointment required). Even in case of unexpected weather, you can also move to the indoor restaurant. From time to time, there are guests to hold birthday party or group party
every festival, the owner hopes to celebrate with his dog. Six degrees will introce festival food to let dogs taste the festival< br />

5.

the Internet is a double-edged sword. Many fraud cases are also generated through the Internet for colleagues who speed up the dissemination of information. So how much money can be cheated online? Generally speaking, if the amount of money cheated reaches 2000 yuan to 5000 yuan, it will reach the standard of filing a case of fraud. Different places may vary according to different economic development. If the amount is small and does not reach 2000 yuan, it does not constitute a crime of fraud, but if it violates public security, it will be detained for 5 to 15 days and fined less than 1000 yuan according to the law on punishment of public security administration. However, if the total amount of fraud exceeds 2000-5000, the criminal responsibility of the perpetrator can be investigated. Article 266 of the criminal law stipulates that whoever swindles public or private property, if the amount is relatively large, shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance and shall also, or shall only, be fined; If the amount is huge or if there are other serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than 10 years and shall also be fined; If the amount is especially huge or if there are other especially serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than 10 years or life imprisonment and shall also be fined or have his property confiscated. Where there are other provisions in this law, such provisions shall prevail. Legal basis: Article 266 of the criminal law of the people's Republic of China who swindles public or private property, if the amount is relatively large, shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance, and shall also, or shall only, be fined; If the amount is huge or if there are other serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than 10 years and shall also be fined; If the amount is especially huge or if there are other especially serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than 10 years or life imprisonment and shall also be fined or have his property confiscated. Where there are other provisions in this law, such provisions shall prevail
