Melting and solidifying notesHere are the notes on melting and solidifying:
** 1. Melt **
1. ** Concepts **
- The process of changing a substance from a solid state to a liquid state was called melting, and this process was a heat absorption process. For example, ice turning into water, iron turning into molten iron, ice cream turning soft, candle wax turning into wax water, glass melting after being heated, and so on.
2. ** Crystal Melts **
- ** Condition **: First, it can only be melted when it reaches the melting point. Second, it must be continuously heated.
- [Special characteristic: Although it continuously absorbs heat during the melting process, the temperature remains unchanged.] For example, crystals such as sea waves, ice, and metal would show such characteristics when melted.
- ** Image **: In the melting image of the crystal, the A and B segments are solid, the B and C segments are solid-liquid, and the C and D segments are liquid.
3. ** Amorphous Melting **: There is no fixed melting point, such as wax, asphalt, glass, pine resin, etc.
** 2. Solidification **
1. ** Concepts **
- The process of changing a substance from a liquid state to a solid state was called solidifying. This process was an exhalation of heat. For example, freezing water, pouring molten iron from a steel-making furnace onto a mold to solidify into a tool, solidifying wax dripping from a burning candle, solidifying animal fat after cooling down, and so on were all solidifying phenomena.
2. ** Crystal Solidification **
- ** Freezing point **: When a crystal is solidified, the temperature does not change. This temperature is called the freezing point of the crystal. The freezing point and melting point of the same crystal are the same.
- [Special characteristic: The solidifying process is a heat-releasing process. As long as the object is solidifying, it will continuously output heat to the outside world.]
3. [Amorphous Solidification: There is no fixed freezing point.]

Will the ointment and solidifying agent react?Different types of ointment reacted differently with the solidifying agent. For example, when using the PVP cement (waterproof ointment), it can be mixed with the curing agent and used for vertical joint sealing construction; when using the two-component polysulfur sealing paste, the white two-component polysulfur sealing paste (component A) and the black curing agent (component B) should be fully mixed evenly according to the ratio of A: B = 10: 0.8 - 1.2 (component B should be more in winter and less in summer, and a small test should be done before use). However, for other ointment, such as the ointment used for furniture repair and self-spray paint, there was no mention of the reaction with the curing agent. Therefore, it could not be said whether the ointment and curing agent would react. It needed to be determined according to the specific type of ointment.

Summing up experience, solidifying methods, improving resultsThe following are examples of learning from different matters and improving the results:
** I. Business environment optimization **
1. ** Enhancing the autonomy of the park's approval **
- To implement "policy +" and break horizontal barriers in the process of granting power to achieve cooperative granting power. For example, Changsha issued the "Changsha City Park Empowerment Guidance Catalog" according to different categories, granting the park multiple closed-loop management rights through various ways of granting power.
- Eliminate vertical barriers and accurately delegate power. According to the principle of "standardized authorization and differentiated undertaking", carry out "self-selected menu" authorization, implement "one park and one policy", and establish a joint working mechanism between the management department and the administrative approval service department to realize the "double synchronization" of the approval of supervision matters and the sinking of professional technical strength.
- Release the effectiveness of the granting of power to promote the reorganization of power, promote the full coverage of the pilot reform of the relatively concentrated administrative license rights in the parks above the provincial level, and realize the "three synchronization" of the transfer of power concentration, the delegation of power, and the optimization of the granting of power.
2. ** In terms of stimulating the park's innovation and entrepreneur vitality **
- We should do a detailed "system +" and establish a radiation mechanism for system innovation results through "bringing the park along with the district". For example, Changsha used the free trade area as the experimental field for system innovation to explore and launch a number of reform results, and then replicated and promoted the results to other regions according to specific reform ideas.
- To create a "garden within a garden", for example, Changsha economic development zone through the introduction of relevant guidance, pilot construction of small and micro parks to improve the average benefit per mu, relax planning indicators and property rights division requirements to build industrial complex, so that enterprises can quickly develop.
3. ** Landing Acceleration Release **
- We should do a good job of "service +" and closely follow the needs of enterprises to create "help agency" methods. For example, Changsha promoted the full coverage of professional "help agency" teams in the park, and established a comprehensive service "help agency" team for the project application personnel. For example, Changsha High-tech Zone established a special service office for specific enterprises and took various measures to speed up the approval speed.
** 2. Military construction **
1. Each unit should fully integrate themselves and the actual task when undertaking the pilot task, deeply explore the essential law of the development of things, find new problems and discover new experiences.
2. When you summarize your experience, you should avoid discussing it and imagining it out of thin air. You should not pursue flowery rhetoric and break away from practice. You should not pursue sensational effects and exaggerate it at will.

3. Combat effectiveness was the fundamental standard to ensure that the experience and methods summarized were usable, useful, and practical, so that other units could adapt to it, use it, and follow it, forming a good construction atmosphere.
** 3. Health Creation **
1. In combination with the theme of the Patriotic Health Month, the "Spring Breeze Action" was arranged for environmental hygiene renovation and promotion. Various publicity methods were used to organize various personnel to enter the community, government agencies, and schools for publicity work.
2. Comprehensively implement the measures according to the implementation plan, and organize various personnel to participate in the renovation of environmental hygiene in key areas according to the requirements of the evaluation dial indicator to meet the corresponding renovation standards.
3. With daily assessment as the main focus, the assessment will be divided into two stages to assign points and supervise the implementation of the work. Each unit will organize environmental hygiene cleaning activities within its jurisdiction, focusing on the comprehensive improvement of urban and rural environmental hygiene, biological control of disease carriers, etc.
4. We should improve the working mechanism, examine the problems in an all-round way, analyze the causes in depth, solve the practical problems that the masses are concerned about, summarize the experience and practices, solidify the results, and establish and improve the long-term management mechanism of environmental hygiene.
5. Make use of new media to publicize the significance of the activities, publicize advanced models, smooth supervision channels, accept the supervision of the society and the masses, strengthen supervision and inspection, and rectify the problems found within a time limit.
** IV. Work of the NPC (Take the relevant training of the Standing Committee of the NPC of Nujiang Prefecture as an example)**

2. Give full play to the advantages of the county-level people's congress and its standing committee, such as giving full play to the advantages of the representative body to carry out legal research to provide reference for the formulation of laws, giving full play to the advantages of the legal supervision power to make suggestions for the establishment, revision and abolition of local laws and regulations, and at the same time strengthen the filing and review of standardized documents, etc.
** 5. Health and Parenting **
1. In terms of health care, he could summarize the experience of simple health habits to improve children's health, such as chiropody in the morning, back rubbing, and abdominal rubbing at night. Habits such as improving yang qi, improving vitality, improving immunity, and improving picky eaters who did not gain weight. These experiences could be continuously promoted and applied to daily child care work.

convertible bondConvertible bonds were a form of financing between debt and equity. It was a bond that could be converted into a listed company's stock. It had the advantages of bonds and stocks. The investor could choose to convert or hold the Convertible Bond according to market conditions. One of the advantages of a convertible-bond was that it avoided valuing the company, especially for start-ups, which could avoid the risk of shares being diluted. Convertible bonds were relatively flexible. They could be bought and sold on the same day, and there was no limit on the price. Convertible bonds could also enjoy the benefits of stocks and the security of bonds. The maturity yield of some of the Convertible Bond had already exceeded the market interest rate. Although there was no hope of converting these Convertible Bond shares into shares, the terms of the sale that were nearing maturity could also bring higher fixed income to investors. In general, the Convertible Bond was a valuable investment tool.
bid bondThe bid bond, also known as the bid guarantee, refers to the written guarantee issued by the bank to the bidder at the request of the bidder (the guarantor) when the project is being tendered.
