吡喃型糖在溶液或固体状态时，其优势构象是（）。
正确答案：椅式构象，椅式
- 1.在用冒泡排序对数5、30、25、15进行升序排序的过程中，进行了3次交换。In the bubble sort ascending order of number 5, 30, 25 and 15, three exchanges were made.
- 2.如果知道100个元素被分配到二维数组A中，则A的两个下标都必须是从0到9，即A必须是10行和10列。If you know that 100 elements are assigned to a two-dimensional array A, the two subscripts of A must be from 0 to 9, that is, A must be 10 rows and 10 columns.
- 3.一维数组和二维数组必须在同一个语句中声明。One-dimensional arrays and two-dimensional arrays must be declared in the same statement.
- 4.如下声明的数组Character，它表示的字符串长度为10：Declare Chr[10] As CharacterThe array Character declared below represents a string length of 10:Declare Chr [10] As Character
- 5.在使用二分查找法之前要求数据已经排好序。Before using the binary search method, the data should be ordered.
- 6.二分查找法只能用于数值型数据。Binary search method can only be used for numerical data.
- 7.冒泡排序方法不能用来把数值数据按照降序排序。 Bubble sorting cannot be used to sort numeric data in descending order.
- 8.在两个平行数组中，所有对应的元素都必须数据类型相同。In both parallel arrays, all corresponding elements must have the same data type.
- 9.下面的语句：Declare Array1[10], Array2[20] As Integer为200个变量分配了空间。The following statement:Declare Array 1 [10], Array 2 [20] As IntegerStorage space was allocated for 200 variables.
- 10.如果一个声明语句分配100个存储空间给一个数组，那么程序必须给这个数组的100个元素都赋值。If allocates 100 storage spaces to an array, the program must assign 100 elements to the array.
