布朗尼和菠萝芝士蛋糕都有一个临界值，因为它们的值受到了符号约束的限制。
The brownie and pineapple cheesecake have a marginal value, because their value is at the limit of their sign constraints.
UML2已经通过去掉“in - line”约束，增加一个叫做组合碎片的符号元件，解决了这一个问题。
UML 2 has addressed this problem by removing the "in-line" guard and adding a notation element called a Combined Fragment.
此方案在推理过程中运用了约束传播和符号代数的方法，预测所有可能合理的配置信息。
The basic idea in this approach is to predict all reasonable spatial configurations of a mechanism using constrain spread and sign algebra.
采用约束关系依赖图(CRDG)表达耦合约束之间的依赖关系，从而建立数值与符号耦合约束模型。
A constraint relation dependence graph (CRDG) is applied to express the dependence of coupling constraints, and establish the numerical and symbolic coupling constraints model.
通过自然的符号叠加形成了编码约束关系，不仅大幅度的提高了系统的频谱效率，而且有效的提高了系统性能。
Based on the overlapped symbols which can achieve coding constrain, it can be improved frequency efficiency and system performance.
然后交错每个连续四进位输出符号的位，从而产生具有全局且交错的连串长度约束的输出比特流。
The bits of each successive 4-ary output symbol are then interleaved, producing an output bit-stream which has global and interleaved run-length constraints.
“如果图谱中的人种符号受到限制，那么用户的表达能力也会受到约束——人们会觉得表情符号无法充分表达自己。”他说道。
"If they restrict the sort of people who are used in the images it restricts users' expressive power — people won't feel that the emoji speak for them, " he says.
使所述四进位输出符号的位反相将产生具有(G,i)约束的输出比特流，如在反向串连调制系统中所使用的PRML (G, i)码中那样。
Inverting the bits of the 4-ary output symbols produces an output bit-stream with (g, I) -constraints as in the PRML (g, I) codes used in reverse-concatenation modulation systems.
记住，约束也是一种艺术，尤其是当你运用色彩和符号时。
Remember that limitations are also an art form, both when applied to colors and form.
