What is the purpose of checking the light reaction?The purpose of the light response examination was mainly to assess whether the newborn had light perception. Before the age of 6, it was a critical period for children's visual function and eyeball structure to mature. The full moon health management after birth included light response examination, through which early detection and intervention could be achieved. In addition, from the perspective of eye fatigue, the light reaction test could detect the change in the light intensity through equipment detection, and reduce the probability of students being short-sighted through human intervention. Moreover, a good indoor lighting environment could allow students to easily see the learning content and spend more time and energy on learning, which played a good supporting role in the learning process.

Welcome the meaning and purpose of the hero's returnThe following are some of the main points of the essay comment on the meaning and purpose of welcoming the return of heroes:
** I. Thematic Description **
1. ** Deep understanding **
- If the essay could point out that welcoming the return of a hero was a respect and recognition of the hero's dedication and sacrifice, it would be a very high highlight. For example, students mentioned that heroes had made great contributions in different fields such as war, anti-epidemic, aerospace, and so on. Their return symbolized victory, hope, and glory. The comment could be written as: "They have a deep understanding of the meaning of welcoming the return of heroes and accurately grasp the respect for heroes behind this behavior."
- If the essay was only on the surface, such as simply saying that the hero was happy to return and did not dig deeper into the meaning, the comment could remind him that the theme was shallow, and he should further think about the deeper meaning of affirming the value of the hero's behavior behind welcoming the hero's return.
2. ** Comprehensiveness **
- For those essays that could explore the meaning and purpose from multiple perspectives, such as from the social level (motivating the people, promoting positive energy), cultural level (inheriting the hero's culture, strengthening national cohesion), historical level (remembering history, inheriting the hero's spirit), etc., the comment could be praised as "a comprehensive and systematic explanation of the meaning and purpose of welcoming the hero's return. It is analyzed from multiple levels and shows a rich perspective of thinking."
- If the perspective was simple, such as only discussing from the perspective of social motivation, the comment could lead to the following: "The perspective of the essay's meaning is slightly simple. You can try to enrich the discussion of the meaning and purpose of welcoming the return of heroes from more dimensions such as culture and history."
** 2. Organization of content **
1. ** Logically coherent **
- When the logic of each part of the essay was close, such as first describing the deeds of the heroes, then naturally drawing out the meaning of their return, and then discussing the purpose of welcoming them back, layer by layer, the comment could be "logically coherent, the discussion level is clear, from the deeds of the heroes to the meaning of their return to the purpose of welcoming them, all linked together to make the article clear."
- If the logic jumps, such as suddenly jumping from the meaning of the hero's return to an unrelated topic and then returning to the purpose, the comment should point out that "the logical cohesion is insufficient, and there is a leap in thinking during the discussion. The logical connection between the various parts should be strengthened."
2. ** Supporting evidence **
- If the student could use rich examples as evidence, such as mentioning the specific deeds of medical staff when welcoming the return of the anti-epidemic hero, or listing the Shenzhou spaceship related events when welcoming the return of the space hero, the comment could be written as "The evidence is rich and specific, and through many examples, it strongly supports the discussion on the meaning and purpose of welcoming the return of the hero."
- If there is a lack of evidence or the evidence is inappropriate, such as only general statements without actual examples, or the examples are not related to the topic, the comment can remind you that the evidence is insufficient or not appropriate enough. More targeted examples should be added to enhance the persuasiveness of the article.
** 3. Language expression **
1. ** Accuracy **
- For an essay that was accurate and clearly expressed, such as the accurate use of words related to the theme such as "reverence,""memory," and "inheritance," the comment could be written as "accurate language, appropriate words, and well conveyed the meaning and purpose of welcoming the hero's return."
- If there is an inappropriate use of words, such as "respect" being written as "admiration"(although the meaning is similar but there is a usage error), the comment can point out that "some words are not used accurately, and attention should be paid to the standard of the words used."
2. ** Affective **
- If the language of the essay was infectious and could resonate with the readers 'emotions, such as using a lyrical sentence,"The return of heroes is the light of hope returning to the earth. How can we not welcome them with the most passionate heart?" The comment could praise,"The language is infectious and can touch the readers' emotions, enhancing the expressiveness of the article in expressing the meaning and purpose of welcoming the return of heroes."
- If the language was plain and uninteresting, like a running account, the comment could suggest,"The language is relatively plain. You can add some emotional expressions to enhance the appeal of the article."

What is the purpose of adjusting ph by the aluminum phosphorous acid reaction?The adjustment of the pH-value in the aluminum phosphorous acid reaction has an important purpose. From the point of view of the dissolution of the deposit, the pH would affect the dissolution of aluminum phosphorous. When the ideal pH was 6, the minimum dissolution of aluminum phosphorous was 0.01g/L. By adjusting the pH to a suitable value, it would help the formation of aluminum phosphorous deposit, thereby achieving a better settling effect and achieving the relevant treatment purposes. For example, in the sewage dephosphorous treatment, it would help to separate and remove phosphorous from the sewage in the form of aluminum phosphorous deposit.
