when the market jumps short, you should buy or sell immediately
many shareholders often follow the market trend to get in and out, and they have no investment ideas of their own, resulting in unnecessary losses
new entrants to the stock market are better to engage in long-term investment and choose hot stocks with high after tax profits and good liquidity< br />" The rope cut into several sections and then connected must be shorter than the original one& quot; Buying and selling stocks, short-term operators are certainly not as profitable as long-term investors in the end

there are more buying opportunities and less selling opportunities in the stock market
as far as investors are concerned, they can get more from short medium-term trend than long-term trend

a. Annuity present value coefficient: (P / A, I, n) = (1 - (1 + I) to the negative nth power) / I
B. compound interest present value coefficient: (P / F, I, n)) = (1 + I) to the negative nth power
where I is the interest rate (discount rate) and N is the number of years. According to these two conditions, we can find the specific corresponding compound interest present value coefficient< There are also two formulas for calculating the final value coefficient:
a. the final value coefficient of annuity: (F / A, I, n) = ((1 + I) to the nth power-1) / I
B. the final value coefficient of compound interest: (F / P, I, n) = (1 + I) to the nth power. Where I is the interest rate and N is the number of interest periods
Sand ratio: SP = sand dosage s / (sand dosage S + gravel dosage g) × 100%
P(A)=P(A[UNK]B1)*P(B1) + P(A[UNK]B2)*P(B2) + ... + P(A[UNK]Bn)*P(Bn)
The calculation formula of CPK is CPK = Cp * (1 - | Ca |)
answer: basically, the proction time of each garment is 2.4 minutes, which is about two and a half minutes.
Linear Congruence Generator (LCG)
select sufficiently large positive integer m and any natural number N0, a, B. the numerical sequence generated by recursive formula:
Ni + 1 = (AF (Ni) + b) mod Mi = 0, 1,..., M-1
is called congruence sequence. When the function f (n) is a linear function, the linear congruence sequence is obtained:
Ni + 1 = (a * Ni + b) mod Mi = 0, 1,..., M-1
the following is the pseudo-random code generated by linear congruence method:
random (n, m, seed, a, b)
{
R0 = seed< br />for i = 1 i<= n I + +)
RI = (a * ri-1 + b) mod m
}
the seed parameter seed can be selected arbitrarily and is often set as the current date or time of the computer; M is a large number, which can be taken as 2W. W is the word length of the computer; A can be any integer between 0.01W and 0.99w
it is very important to select the parameters N0, a, B and m when using recurrence formula to generate uniformly distributed random numbers
for example, if M = 10, a = b = N0 = 7, the generated random sequence is {6, 9, 0, 7, 6, 9,...}, and the period is 4
take M = 16, a = 5, B = 3, N0 = 7, the generated random sequence is {6, 1, 8, 11, 10, 5, 12, 15, 14, 9, 0, 3, 2, 13, 4, 7, 6, 1...}, and the period is 16
take M = 8, a = 5, B = 1, N0 = 1, the generated random sequence is {6, 7, 4, 5, 2, 3, 0, 1, 6, 7...}, and the period is 8.
= 4 * 56 / (12 * 30 + 4816 + 16 * 812 + 14 * 780 + 32 * 8 + 4 * 56).
(2) calculation of iron supplement: total iron deficiency [Mg] = body weight [kg] x (HB target value actual value) [g / l] x0.238 + stored iron [Mg].
stored iron = 10mg / kg body weight (& lt; The initial diagnosis should be reconsidered if no changes in hematological parameters were observed 1-2 weeks after administration. The dose of iron supplement for patients with blood loss and supporting autologous blood donation was calculated as follows:
the amount of iron needed to be supplemented [Mg] = the unit amount of blood loss x200.2. The formula for calculating iron weight: (1) gross weight, (2) net weight is the symmetry of "gross weight". The gross weight of steel minus the weight of packing material is called net weight. In the purchase and sale of steel, it is generally calculated by net weight.
(3) tare weight, The weight of steel packaging material is called tare weight.
(4) weight ton is the weight unit used in calculating freight according to gross weight of steel. The legal unit of measurement is ton (1000kg), and long ton (1016.16kg) Short tons (US weight unit: 907.18kg).
(5) billing weight is also called "billing ton" or "freight ton". The transportation department charges the steel weight of freight. Different modes of transportation have different calculation standards and methods. For example, for railway vehicle transportation, the marked load of the freight car is generally used as the billing weight (6) calculation of theoretical weight of steel:
the unit of measurement of theoretical weight of steel is kg. The basic formula is: w (weight, kg) = f (sectional area, mm2) × L (length, m) ×ρ Density, g / cm3) × 1/1000 .
