question 1: what do you mean by parallel in the same plane? Two lines that don't intersect are called parallel lines.
parallel lines: in the same plane, two lines that do not intersect are called parallel lines, and the parallel relationship is mutual. Two lines perpendicular to the same line are parallel. A little, there is one and only one straight line parallel to this straight line.
Method for judging parallel lines:
1. The same angle is equal and two straight lines are parallel.
2. The internal dislocation angles are equal and the two straight lines are parallel.
3. The inner angles of the same side are complementary, and the two straight lines are parallel.
property theorem of parallel lines:
1. Two lines are parallel, and their congruence angles are equal.
2. Two straight lines are parallel, and the internal dislocation angles are equal.
3. The two straight lines are parallel and complementary to each other.
Parallel lines
Singing: Kym
is not safe. When you say how sweet she smiles
How do you realize now
how obvious this feeling is?
Suddenly happy
So we are stranded between you and me
We are like two parallel lines
We can never face to face frankly
I am on your left and you are on your right
. P > We are just two parallel lines.
No matter how far we go, we never meet.
Tears can only be contained in our hearts.
I'm afraid that my vision will be blurred.
Question 2: What is the parallel mode? It can be divided into major and minor, one ***24. Their initial sounds are 12 different sounds contained in an octave, namely C, C-sharp (that is, D-sharp), D-sharp (that is, E-sharp), F-sharp (that is, G-sharp), G-sharp (that is, A-sharp) and B-sharp. Each initial sound leads to a major and a minor, so that 12 times 2 is 24 major and minor tones.
A parallel tone refers to a tone with the same initial tone but different tonality. For example, the parallel key in C minor is C major, the parallel key in D major is D minor, and the parallel key in A flat major is G minor. Such a group is called parallel major and minor tones.
there is also a combination called relative major and minor. for example, the relative minor in c major is a minor. This classification does not look at the same initial sound, but the same ascending and descending symbols. For example, there are no ascending and descending symbols in C major and A minor; D major and its relationship. B minor contains two sharp signs, which are different.
Parallel size and relational size are two concepts, so don't confuse them.
Question 3: What is a parallel sequential reaction? Parallel-sequential reaction:
When raw materials are cracked, they react in several directions at the same time, which is called parallel reaction; At the same time, with the increase of reaction depth, the intermediate products will continue to react, which is called sequential reaction.
(It can be understood as follows:
At high temperature, recombination is decomposed into light components, such as gasoline and diesel oil, and then further decomposed into light hydrocarbons, such as dry gas, liquefied gas and coke, which is a sequential reaction; The heavy components may directly generate coke, light hydrocarbons, etc. under the catalyst with high activity, which is a parallel reaction. )
an important feature of parallel sequential reaction is that the reaction depth has an important influence on the distribution of product yield, that is, with the extension of reaction time and the increase of conversion depth, the yield of final product gas and coke will always increase, while the yield of intermediate products such as light oil and light fuel oil will increase at first, and then decrease after a highest stage. This is because after reaching a certain reaction depth and deepening the reaction, the intermediate product will be further decomposed into lighter distillation points (for example, light oil will be decomposed into gas and light fuel oil will be decomposed into light oil), and its decomposition speed is higher than the generation speed. It is customary to say that the reaction in which the product of the primary reaction continues is a secondary reaction.
According to specific examples, it is easier to understand:
Question 4: What is a parallel fund? A parallel fund means that two private funds are set up at home and abroad at the same time, and the same manager is entrusted to conduct investment management. When a project is found, the two funds invest at the same time, generally accounting for 5% of the investment.
Advantages of investment strategy of parallel funds:
1) Alternative functions. If domestic funds cannot legally complete foreign exchange settlement, overseas funds will directly invest in domestic projects. 2) Fund allocation function. If domestic funds are short of funds, it may be agreed that overseas funds will provide more funds, and vice versa.
3) conversion function. If the domestic or overseas legal environment changes, all of them can be transferred to funds with better legal environment for investment. 4) Policy configuration function. Fund managers can decide which fund to invest in according to the changes in tax, legal and other environments and the principle of being most beneficial to investors.
Potential benefits of parallel funds:
Parallel funds avoid capital flow restrictions. Due to the restrictions on RMB settlement under capital, this structure tries to minimize the difficulties caused by capital flow restrictions in China. This approach seeks to minimize the examination and approval required by the foreign exchange control regulations applicable to foreign investors' domestic investment and domestic investors' overseas investment.
question 5: what is "parallel reading"? There are many on the Internet, which are very detailed: First of all, the order of IELTS reading should be made clear: the so-called order refers to the order in which the answers to the questions appear in the article. The big questions are out of order, while the small questions in a class of questions are in order. For example, there are three types of questions in an article, the first is choice (1-3), and the second is T/F/NG (4-7). In the first question type, questions 1-3 are orderly, but the position of question 4 in the article is not necessarily behind the third question, perhaps behind the first question or the second question. Therefore, it is very important to grasp the order of reading the article.
Here are the methods of parallel reading:
Suppose this article has 11 questions, And the order in which the answers to the 11 questions appear in the article is as follows:
... 1 ... 4 ............
... 2 ... 3 ...
5 ... 8 ... 9 ...
6 ... 1 ... ...........
As can be seen from the above article, questions 1, 2 and 3 are out of order, but the small questions in each question are in order, that is, 1-3, 4-7 and 8-11 are in order.
Method: In the first step, we go with the first question of the first type and the first question of the second type (questions 1 and 4). At this point, we read intensively and make the first question.
In the second step, after making the first question, we read it with the second topic of the first type of question and the first topic of the second type of question (questions 2 and 4), and then found the fourth question when reading. After reading intensively, we made it with the second topic of the first type of question and the second topic of the second type of question (questions 2 and 5). After making it, I read it with questions 3 and 5. Then I saw the answer to question 3, read it intensively, and made question 3. At this time, the first type of body shape has been finished, so we read it with questions 5 and the first item of the third type of question, that is, (questions 5 and 8) ... So we can finish reading at one time and save a lot of time.
Question 6.
