The query results of Linq may follow 2 & #186;, 2 & #185;, 2 & #178;,... growth calculation, and the query results of linq.

The query results of Linq may follow 2 °, 2 °, 2 ²,... growth calculation, and the query results of linq.

        static void Main(string[] args)        {            int[] array = new int[] { 102, 12, 23, 412, 22, 14, 45, 65, 33 };            var obj = from item in array                      orderby item ascending                      group item by item / 100;                          foreach (var item in obj)            {                Console.WriteLine(item.ToString());            }            return;        }  

If you are bored and want to write a program using Linq, you will suddenly find this problem. Please refer to the above Code. Ideally, the obj result should be:

{0: [, 65]

1: [102]

4: [412]}

Actual results (Please use monitoring to view the results, and the last extra 0 cannot be printed ):

{0: [,] // optimistic about 8 digits = 23, less than 0

1: [102] // 20

4: [412]} // 20

That is to say, the last multiple Zeros In the 0 group, but this zero is not defined in the original array. How does it appear?

 

Then modify the array int [] array = new int [] {102, 12, 23,412, 22,111,156, 14, 45, 65 };

        public static void Main(string[] args)        {            int[] array = new int[] { 102, 12, 23, 412, 22,111,156, 14, 45, 65, 33,88 };            var obj = from item in array                      orderby item ascending                      group item by item / 100;                        foreach (var item in obj)            {                foreach (var t in item)                {                    Console.Write(t + "\t");                }                Console.WriteLine();            }                        return;        }    

 

The result of this test is (Please use monitoring to check that multiple zeros cannot be printed at the end of group 1 ):

{0: [,] // 8-bit = 23

1: [102,111,156, 0] // 4 digits = 22. If not, add 0.

4: [412]} // 20

 

So I guessThe results of the Linq query may follow 2 °, 2 °, 2 ²,... growth calculation

My amniotic fluid is 135MM in 37 weeks. The placenta is located in the forearm of the uterus. The Fetal echo and fetal position are visible in the stage 2 of placenta maturity;

Double top diameter: bpd represents the diameter of both sides of the fetal head, which is the measurement data of the diameter of both sides of the fetal head and is also one of the indicators for calculating the fetal size. According to the general rule, three months of pregnancy is less than 3 cm; after five months of pregnancy, basically consistent with the month of pregnancy, that is, 28 weeks of pregnancy (7 months) when bpd is about 7 cm, when 32 weeks (8 months) is about 8 cm, and so on. After 8 months of pregnancy, the average weekly growth of about 0.2 cm is normal.
Placenta position: the position of the placenta on the uterine wall. The normal thickness of the placenta should be between 2.5 and ~ Between 5 cm; in some reports, the placenta is divided into three levels. Level I is the early stage of placenta maturity, with even echo ~ This change is visible within 32 weeks; Level ii indicates that the placenta is near maturity; Level iii indicates that the placenta is mature. The closer the term is, the more mature the placenta, the more uneven the echo. If the placenta position is too low, it may block the entrance and affect normal childbirth.
Amniotic fluid range: the value of amniotic fluid range can indirectly determine whether the fetus is abnormal. Generally, the amniotic fluid depth is 3 ~ 7 cm is normal, more than 7 cm is the increase of amniotic fluid, less than 3 cm is the decrease of amniotic fluid. If the amniotic fluid scope is too large, it indicates that the fetal neural tube or gastrointestinal tract may be abnormal; if the amniotic fluid scope is too small, it may be a problem with the fetal urinary system.
Fetal movement: fetal movement can indicate the normal condition of the fetus in the palace, which is an important signal used to predict the safety of the fetus in the palace. From 18th ~ After 20 weeks, most expectant mothers may feel fetal movements, starting from mild, with fewer times. 28 ~ 32 weeks, the most fetal movement, 36 ~ pregnant ~ After 38 weeks, the fetal movement and frequency gradually decreased. Fetal movement: 8 ~ Average at 12 hours, 2 ~ in the afternoon ~ Minimum 3 hours, 6 ~ 10 is the most frequent. If the report states that "yes" and "strong" are normal, "no" and "weak" may be abnormal or the fetus is sleeping, and comprehensive analysis should be carried out in conjunction with other projects.

The fetal position indicates the position of the mother's pelvis, that is, the four-phase position of the pelvis-left front, right front, left back, right back.
The bone shown at the top is the occipital bone (o), the hip indicated at the top is the sacrum (s), and the lower Chin bone (mentum, abbreviation: m); shoulder first dew represents the shoulder blade (scapula, Abbreviation: SC ).
There are three methods to describe the fetal position:
1. represents the Left or Right side of the pelvis, abbreviated as left (l) or right (r );
2. indicates the name of the bone. For example, if the top part is "pillow", that is, "o", the top part is "Si", that is, "s", and the top part is "chin ", that is, "m", and "SC ";
3. represents the bone before, after, or transverse pelvis. For example, the top first dew, the left occipital bone in the pelvis, toward the front, the fetal position is left before the pillow (loa), is the most common fetal position.
The abbreviation of each birthpoint is as follows:
There are six fetal positions for first exposure:
Left pillow Front (loa) left pillow horizontal (lot) left pillow back (lop) right pillow Front (roa) right pillow horizontal (rot) right pillow back (rop)
There are six types of fetal bits for buttocks:
Left anterior (lsa) left anterior (lst) left anterior (lsp) right anterior (rsa) right anterior (rst) Right posterior (rsp)

There are six types of fetal positions:
Left front (lma) left front (lmt) left front (lmp) Right front (rma) Right front (rmt) Right rear (rmp)
There are four fetal positions for shoulder first dew:
Left shoulder Front (lsca) left shoulder back (lscp) Right Shoulder Front (rsca) Right shoulder back (rscp)

Ac-abdominal circumference
Aptd is the thickness of the abdomen, also known as the "abdominal diameter ". This data needs to be measured to check the developmental status of the fetal abdomen and to estimate the fetal weight.
Bdp-the length of the longest part between the left and right sides of the Double top diameter head, also known as "large horizontal diameter of the head ". Bpd is often used for prediction when the pre-production date cannot be determined through crl in the initial stage. After the middle stage, this data is often required to be measured when the fetal weight is estimated.
Crl-head hip Length indicates the length of the head hip, which is the maximum long axis of the Parallel measurement of the fetal longitudinal axis. It is mainly used to determine the pregnancy 7 ~ 12 weeks of age.
Hc-head circumference
Fl-the length of the thigh bone of the femoral fetus, also known as "thigh bone length ". The thigh bone refers to the length from the root of the thigh to the knee. Generally in pregnancy 20 ...... the remaining full text>
