Just click on the arena to establish the competition mode of Room 2 Arena. Traditional 4K Traditional 4k Rhythm 4k Rhythm 8k Team Mode 3QQ Hyun Dance Tickets can be purchased only by purchasing 1qb = 10 tickets in the game mall. Two tickets are needed to open the first-level honor room, the first place will get 4 10 honor points, and the 00-level task will be given 10 tickets. When you go in, dance with others. (PK must have at least two tickets at a time. There are fewer people in PK now. 24K suggests that you invite people above 10. If the room is full, the first place is 12, the second place is 8: 00, and the third place is 6: 00. In addition, 1 is the room level that requires tickets, which represents the number of tickets used in the arena. Level 0 room 10, level 2 room 30, level 3 room 50. Second, 6 o'clock. Third, three o'clock The rest is 1 minute. (One game, two tickets, second class room: the first 60 points. The second one is 30 o'clock. The third point is 15. The rest are at 5 o'clock.

How to distinguish primary, secondary and tertiary steel bars? There are HPB235 and Q235 in the first level, and HPB300 in the new one.

The second floor has HRB335,

The third level has HRB400.

What's the difference between daily, primary, secondary and tertiary maintenance of automobiles? How to distinguish them? Please, the center of Great God's first-class maintenance is lubrication and fastening. General job requirements are as follows: Driver's job items:

According to the current code, roof waterproofing is divided into Grade I and Grade II: Grade I is used for important buildings and high-rise buildings, usually two waterproof layers; Class II is used for general buildings, usually waterproof and fortified.

Is the level of the hospital first-class or third-class? Please, great gods must be tertiary hospitals. The general county people's hospital is a first-class hospital, and the people's hospital in prefecture-level city is a second-class hospital. The people's hospital in the provincial capital is a top three hospital.

What's the difference between the full level and the full level of Dnf? Please push away and play more.

What are the second and third magic weapons of ES? Please, the magic weapon of Great God Level 2 is to halve the magic cost. What's your name? I forgot that the third level is compassion. Just like the Dharma explosion. Skill 120 can push more than 800 blood.

What's the difference between grade one steel, grade two steel and grade three steel? Please, thank you. The strength of clothes is different from the maximum strength, and so is the elongation. There are four types of steel bars: HPB235, diode, HRB335, HRB400 and RRB400. Numbers represent the standard value of strength. The higher the strength, the higher the price. For example, HPB235 is round steel, and HRB335 and HRB400 are ribbed steel bars. The elastic modulus of the first-grade steel bar is also different from that of the second-grade steel bar (the second-grade steel bar is the same), and so on ~ ~ There are many kinds of commonly used steel bars, which are usually classified according to chemical composition, production technology, rolling shape, supply form, diameter and application in the structure: (1) Smooth steel bars are classified according to rolling shape: I-grade steel bars (Q235 steel bars) are all rolled into smooth surfaces. (2) Ribbed steel bars: there are three types: spiral, herringbone and crescent. Generally, the second and third grade steel bars are rolled into herringbone, and the fourth grade steel bars are rolled into spiral and crescent shapes. (3) Steel wire (low carbon steel wire and carbon steel wire) and steel strand. (4) Cold rolled and twisted steel bars: cold rolled and cold twisted. (2) Steel wire (3~5mm in diameter), fine steel bar (6~ 10mm in diameter) and coarse steel bar (above 22mm in diameter) are classified according to their diameters. (3) According to the mechanical efficiency, I-grade rebar (grade 235/370); Grade Ⅱ rebar (335/510); Grade Ⅲ steel bars (370/570) and Grade Ⅳ steel bars (540/835) (4) are divided into hot rolled, cold rolled and cold drawn steel bars according to the production process, and there are heat-treated steel bars made of Grade Ⅳ steel bars, which have higher strength than the former. (5) The reinforcement arranged in the reinforced concrete structure, such as compression reinforcement, tension reinforcement, vertical reinforcement, distribution reinforcement and stirrup, can be divided into the following types according to their functions in the structure: 1. Stress bar-steel bar subjected to tensile and compressive stress. 2. Stirrup-it bears a part of diagonal tensile stress and fixes the position of the reinforced bar, which is mostly used in beams and columns. 3. Vertical bar installation-used to fix the position of steel hoop in the beam and form the steel skeleton in the beam. 4. Distributed steel bars-used for roof panels and floors, arranged vertically with the stressed steel bars of the plates, which evenly transfer the bearing weight to the stressed steel bars, fix the position of the stressed steel bars, and resist the temperature deformation caused by thermal expansion and contraction. 5. Others-structural steel bars configured due to structural requirements of members or construction and installation needs. Such as waist tendons, embedded anchor bars and rings. I hope I can help you, thank you for your adoption!
