During gradual heating at certain temperatures, a number of complex physicochemical transformations occur, including the transition from opal to cristobalite.

The number of layers of a session in a link is the maximum of the number of layers of the session receivers downstream.
Proportional fairness is a form of fairness, which distributes bandwidth without a bias in favor of flows using a smaller number of hops.
Further, a very large number of layers can delay convergence since layers are added one at a time.
It is not trivial in the choice of fine-grained or course-grained layered data organization.
In a receiver-driven algorithm, the source typically generates a fixed number of layers at a coarse set of fixed rates.

These compounds are precipitated in the grain boundaries, which make silicon and iron concentration increased in grain boundaries and the reduction of the impurities in crystals, accompanied with the reduction of resistance and the increase of conductivity.

In order to manufacture a product of unique geometry from the required material, it is necessary to fulfill a number of technological conditions.
The strength characteristics of samples made by additive technology with different topology of fiber placement were investigated by a number of authors during tensile tests [12–15].
In addition, the latter must meet a large number of requirements, such as durability, normal operation in a given temperature range, and resistance to dynamic loading.
To study the structure of the samples by optical microscopy, a thin section was prepared from the samples subjected to tensile testing by cutting a small piece of the sample material across the filament and grinding it on moisture-resistant abrasive paper sequentially, starting from paper with a coarse grain P100 to paper with a fine grain P2500 with distilled water.
A certain number of defects in the form of pores are visible on the thin section of sample No. 3.

Currently, a number of new fibers have emerged, such as the new cellulose fibers of TENCEL, modal, bamboo fiber, and Richcel fiber, etc., the new protein fibers such as soy protein fiber and milk protein fiber, the new functional fibers such as chitin fiber and seaweed fiber, and polyester modification fibers with functions like moisture absorption to eliminate perspiration, bacteria resistance, and ultraviolet resistance, etc., as well as the PAL fiber, sourced from grains and other natural raw materials, biodegradable, particularly with its excellent properties and its wide range of applications attracting the global attention in the textile materials sector.
Lactic acid can generate glucose, maltose and other sugars through the hydrolysis of grains containing starch materials（such as corns, potatoes, sugar cane wastes, and beet wastes）, and it can be made by the method of special saccharomycete fermentation.
However, there are also deficiencies in the two-step method, such as a long production process flow, high production costs, complex processes, and a large number of reagents to be consumed in the production, and so on.
Currently, there are a large number of reports about the synthesis researches on such polymers.
The formations of irregular spots and discontinuous stripes are mainly due to the existence of a large number of non-crystalline parts in the PLA, which can be decomposed quickly in the presence of water, bacteria, and oxygen.

It is found that accuracy of rule based learning increases with the number of iteration. 1.
The higher the fitness of individual, the larger the number of next generation is.
The smaller the fitness of individual, the smaller the number of next generation is; or even the next generation will be eliminated.
If the total number of the training data is N; and the multiply accumulate computation of the weight and the actual value of each gene distribute at different intervals; the length of each interval is ; the number of data packet distributed in each interval is .

During the last thirty years a number of process variants have been developed and summarised under the topic "semi solid metal forming" (SSM) [3].
Independent of the process route, generally, distinct microstructure consisting of globular solid grains with surrounding liquid phase (see fig. 1) is targeted to take advantage of its flow behaviour (thixotropy) in the forming process.
For the case of SIMA feedstock, the material first recrystallises and then as melting initiates, grain boundary penetration occurs which leads to the isolation of discrete particles within a liquid matrix [4].
To achieve the finely distributed globular solid grains some different measures, for instance application of a slope or vibration, can be applied to induce all-over nucleation during solidification.
For a metallic tool material hot cracking occurs after a great number of thermoshock cycles as a consequence of thermal fatigue.

At this stage, the surface of the sample forms a passivation layer, no arc spots appear, but there are a large number of bubbles coming out, which is a prerequisite for the appearance of micro-arc oxidation[19-20].
The second stage is the stage of micro-arc oxidation discharge, corresponding to the high voltage platform on the curve, this stage formally enters the stage of micro-arc oxidation treatment, the length of micro-arc oxidation is determined by the process parameters[21-22], this stage the sample surface appears a large number of small flickering and fast moving arc spots, accompanied by exploding sound and a large number of bubbles out.
TEM observations show that the grains formed by micro-arc oxidation in the aluminate system are very fine, mainly in the form of nanocrystals and microcrystals.
According to the nucleation and growth kinetics, if the cooling rate is very large, the formed grains will be very fine.
Therefore, during the micro-arc oxidation of magnesium alloy, the grains mainly exist as nanocrystals and microcrystals.

With the decreasing of arable land, as well as rural labour migration and the increase of the multiple crop indexes, many factors are in a relatively stable state, including crop sown area, grain yield and carbon emissions.
Since the Middle of 1990s, consecutive five-year grain harvest result in a growing problem of poor grain selling in China.
From the point of view of carbon emissions structure, fertilizer carbon emissions are number one, accounting for as much as 62.84%.
Chinese grain security has become the increasingly prominent problem.
With the industrialization advancement speeding up day by day and the international grain market becoming more and more complex, it is of great significance to the smooth operation of the national economy for Guangdong to improve the comprehensive grain production capacity by increasing investment in agriculture, taking into account that Guangdong province is China's largest food sale region with the largest demand-supply gap.
