separation theorem

基本解释

For many years, I have tried to come up with a way to explain the portfolio separation theorem that does not involve matrix calculus.
許多年來，我一直在思考一個不需要用矩陣代數來解釋投資組郃分離理論的方法。
For many years, I have tried to come up with a way to explain the portfolio separation theorem that does not involve matrix calculus. I think have one now.
許多年來，我一直在思考一個不需要用矩陣代數來解釋投資組郃分離理論的方法。我想現在我已經思考出來了。
The portfolio separation theorem says that the number of portfolios that are needed to produce an optimum allocation is equal to the number of characteristics that investors care about.
而投資組郃分離理論認爲需要産生最優配置的投資組郃的數量等於投資者關心的投資目標的數量。

分離定理
However, the limited wireless channel bandwidth and poor channel conditions restrict design of the source-channel coding system based on the current Shannon separation theorem.
然而無線信道有限的帶寬,惡劣的信道條件使得目前基於Shannon分離定理的信源信道編碼系統的設計顯露出侷限性。
