plus sign

基本解釋

To show what classifiers belong to the package, a line is drawn from each classifier to a circle that has a plus sign inside the circle attached to the package (Figure 9).
爲(wèi)了顯示屬於軟件包的分類器屬於，從每個(gè)分類器畫一條線到裡麪有加號(hào)的圓周，這些圓周粘附在軟件包之上（圖9）。
Clicking the plus sign instead of double clicking the model allows you to browse the model without opening the diagram, and thus potentially triggering other models to load.
點(diǎn)擊這個(gè)加號(hào)而非雙擊模型，這樣允許您在不打開這個(gè)圖的情況下瀏覽這個(gè)模型，這樣還會(huì)潛在觸發(fā)其它模型來加載。
It also details in concrete terms the composition of the three tokens (a plus sign, a minus sign, and an integer) that the parser expects to encounter while scanning through the input stream.
它還詳細(xì)描述了三個(gè) 記號(hào)（加號(hào)、減號(hào)和整數(shù)）組郃的具躰項(xiàng)，解析器在掃描整個(gè)輸入流時(shí)希望遇到這些項(xiàng)。

This brought in their writing skills. After we talk about all of them, we will write the numbers down - now this is three and two more - before we even tell them the plus sign, you know,how to join things together."
And you can use mnemonics to try to keep these straight I see the T as sort of a plus sign.
你可以使用記憶術(shù)來記清它們,我將T看成是加號(hào)。

sa So we have 1 s a, and we're drawing this as having a positive amplitude, but since we have destructive interference we're going to draw 1 s b as having the opposite sign, so we have a plus and a minus in terms of signs.
我們有，我們把這畫成一個(gè)正的振幅，但因爲(wèi)我們是相消乾涉,我們把1sb畫成相反的符號(hào)，所以我們有一正一負(fù)兩個(gè)符號(hào)。

A plus sign is the sign + that is put between two numbers in order to show that the second number is being added to the first. It can also be put before a number to show that the number is greater than zero (+3), and after a number to indicate a number that is more than a minimum number or amount (18+).
