The African bamboo stalk is a herbaceous plant under the genus Papaya, distributed in the warm rainforests of Sierra Leone to Congo (Kinshasa) in West Africa. The herbaceous plant has a plant height of up to 3 meters, and its inflorescence is born at the base of the stalk on the petiole near the ground. Each inflorescence grows about 12 pairs of flowers in pairs, and the flowers are purple-red. The fruit grows mainly in the roots, but part of it is often covered by dead leaves and sediment. This fruit is a triangular fleshy fruit that turns from dark green to brown when first ripened and bright red when fully cooked. There are 1 to 3 dark black seeds in each fruit, and the top of the seed is covered with a flexible membranous sac containing very sweet viscous material. African bamboo buds bloom most of the year, with the highest blooms from February to June and August and October. The fruit is ripened about 3 to 4 months after flowering. The average weight of single seed is 9 grams, double seeds and The fruit of the three seeds weighs an average of 12 grams to 16 grams, and the heaviest fruit can reach more than 40 grams.
How sweet is this fruit? In order to compare the ability of different sugars to produce sweetness, one defines a quantity called "sweetness". Because sucrose is the most important sugar in food, it is used as a benchmark, the sweetness is set to 1, and other sugars are made with sucrose. Compare the individual sweetness. In general, a sweetness of less than 1, indicating no sweetness of sucrose; greater than 1, indicating sweeter than sucrose. There are many substances in nature that produce sweetness and are much sweeter than sucrose. For example, the licorice saponin in licorice has a sweetness of 30 to 50; the stevia extracted from stevia has a sweetness of 200 to 300. The cantan extract extracted from the fruit of the genus Papaya has been determined to be 750 to 1600 times sweeter than sucrose and is the sweetest natural substance in the world. Some people joked that a small fruit is equivalent to ten pounds of sugar.
However, although this fruit is sweet, it is actually a kind of protein. Eating too much will not affect blood sugar.
A measuring instrument for quantitatively evaluating the cylindricity of a cylinder by measuring the actual contour of the cylinder using the precise rotation centerline as the reference standard and the precise linear motion guide rail as the reference standard. It can be used to measure cylindrical shape errors (roundness, cylindricity, straightness, and flatness), position errors (coaxiality and verticality), etc.
The cylindrical Roundness Tester is mainly used to measure the roundness, cylindricity, straightness, concentricity, coaxiality, flatness, parallelism, perpendicularity, surface waviness, discontinuous surface, etc. of various regular and irregular circular workpieces. It can also perform spectrum analysis, wave height analysis, eccentricity, shaft bending analysis, and runout analysis on workpieces.
This device has excellent cost-effectiveness, full measurement capability, and is easy to learn and use.
