WHAT DOES RAZR ROKR RIZR KAZR MEAN

Motorola attaches great importance to Hong Kong's telecom fairs, including the giant booth at ITU Telecom World and the 3G Congress at the Wan Chai Convention Show. It wasn't enough, on the first day of the ITU, Jay Chou, the spokesperson of Greater China, was invited to Hong Kong to release the third Motorokr model E6 globally. The thin ROKR E6 is a Linux smartphone that supports both flat and large SD memory cards with a music button and up to 2GB, just like the iPod nano.

In addition, the headset uses a plug position, which can be connected to a private headset without an adapter, which is convenient enough. This time, we invited Dong Chou, who has a lot of fans, to build momentum, and it is not difficult to sell well.

Kazr Razr Rizr has been shown to you all at once.

Moto's ace series, including the KAZR K1 in multiple colors; The new push cover rizr z3 will meet you. In addition, Moto's new HSDPA phones will also be on display first, including the Motorazr XX, which is a classic V3 shape, plus a video lens, up to the highest speed of HSDPA, megapixel lens, etc.

MotorAXR MaxX, a V3X revision, also supports HSDPA, QVGA pixel screen, 2 million pixel camera, plus external ** button, which is more user-friendly than RAZR.

Where did it appear?

RAZ is a very well-known set of graded books in the United States, which is used in more than 10,000 schools in the United States. According to the difficulty, it is divided into AA, a total of 27 levels from A to Z, AA is the easiest, each page is two or three simple words, and then it gets harder and harder.

Originating from developed countries such as the United States and Canada, and developed in Hong Kong and Taiwan for more than ten years, RAZ is a comprehensive consideration of children's English proficiency, mental development, hobbies and other factors, to provide children with different levels of English reading materials with different levels of difficulty. It is designed to help children find the right level for their level, gradually improving their reading ability through a lot of reading at the same level.

In the RAZ level, Level A includes knowing people's different expressions, different fruits and vegetables, human body parts, things to prepare before going to school, etc., while Level B textbooks will take students to know some animals (such as the habits of pets such as cats and dogs), play games, etc., which are closely related to life.

RAZ is divided into 27 levels according to difficulty, and the 4 levels AA-C correspond to the kindergarten stage; The 7 levels of D-J correspond to the first grade of elementary school in the United States; The six levels of K-P correspond to the second grade of elementary school in the United States; The four levels of Q-T correspond to the third grade of primary school in the United States; The three levels of U-W correspond to the fourth grade of elementary school in the United States; x-z corresponds to the fifth and sixth grades of primary school in the United States (equivalent to high school graduation in China).

The difference between the various versions of raz is that the more popular versions on the market mainly include blue label gift box, star gift box, red label gift box, dream version, matte powder collection, and Dowling collection. In terms of paper, Dowling paper beige is more eye-friendly, but the paper is slightly thinner. The matte powder is a little thicker.

At present, the best quality is the blue label gift box version, and my girl also uses the blue label gift box. The paper is a thickened version. Except for the AA level, which does not have a workbook, all other levels have a workbook.

And this number is the largest. At present, the level is relatively complete. This version is a must-have for those who want to be of high quality.

The second is the star version, which is also a thickened matte fascicle, which is about the same quality as the blue label gift box. Many people also use this version. However, there are not as many numbers as blue labels.

The red label version is also a new version, with a large number of volumes, and the grading catalog is consistent with the official. The paper is thinner than the Blue Star Gift Box version. It's cheaper and more cost-effective. Those who pursue cost-effectiveness can choose this one.

Please rate my service, if you think it's okay, please give a thumbs up, I wish you a happy life and a smooth work, thank you.

Difference Between RA and RZ:

1. The wide range of use is different

Ra is the most important evaluation parameter, and Rz is generally only used to represent relatively short surfaces. In the representation of actual machining, it is more common to use Ra to show the roughness of late staring than Rz.

2. The calculation method is different:

The arithmetic mean deviation Ra is the arithmetic mean of the absolute value of the ordinate z, and therefore the length of a sample.

It is calculated as the sum of the average of the 5 largest profile peak heights and the average of the 5 largest profile valley depths over the sampled length.

3. Accuracy is different:

Because there are not many RZ measurement points, the characteristics of reflecting the height of the microscopic geometry are not as sufficient as the parameters of RA, and it does not have the characteristics of RA more code collision and precision, but it is more convenient to measure than RA.

RAZ is an abbreviation for Reading A to Z, which is a set of English books for graded reading in the United States, and is often abbreviated as RAZ because of its level according to the level of enlightenment aa, a-z, so it is usually abbreviated.
