休上， 本 的 接方法包括 On the break, the connection method of this includes
5 1、 低 到高 的速率特 需求， 配置相座教量的低 通道教 羊元和先 先 5 1. Low to high rate special needs, configure the low channel teaching of the teachings of the phase and the first
2、 將每 低 通道教 羊 的 的先 先 ， 羊 。 2. The first to teach the sheep in each low channel, the sheep.
0 低 O 和FFO的 低 到高 的速率特 需求配置，例 ， 果需要 T 到 T 2 接， 則可 4 FFO ，分別 路 T 等 的 O 。 果需要 T 到 T 3 接， 則可 16 FFO ， FFO 于 路 T 等 的O 。 理想的， FFO 中的 在 介合 的 園內， 以 兔5 出現FFO的 。 但由于 FFO 的 和 的速率不 同， 因而可能出現上 或者下 。 此， 需要 FFO的 速率 控制。 般的， 了防止FFO 出現上 ， 在FFO 快要 滿而沒 有 滿 ， 需要 快FFO 的 速率， 了防止FFO 出現 下 ， 在FFO 快要 而沒有 ， 需要降低FFO 的 0 Low O and FFO low to high rate special demand configuration, for example, if T to T 2 is required, then 4 FFO, respectively, T of the road T, etc. If T to T 3 is required, then 16 FFO and FFO can be used for O of road T and so on. Ideally, the FFO in the FFO is in the garden of the FFO. But because the rate of FFO's sum is not The same, so it may appear up or down. Therefore, the rate control of the FFO is required. In general, to prevent FFO from appearing, the FFO is almost full and not full, and the speed of FFO is required. To prevent FFO from appearing, the FFO is almost there, and the FFO needs to be lowered.
速率。  rate.
此， 可以在FFO 中 水位 以 相 的 滿 ， 上 和下 ， 分別 上水位 和下水位 ， 上水位 FFO 快要 滿而沒有 滿 ， 例 上水位 在 FFO中的 已 增長到 FFO 容量的95%。 下水位 FFO 快要 而沒有 ， 例 下 水位 在 FFO中的 已 降低到 FFO容量的 5%。 需要理解的是， 此 的95%和5% ， 非將上水位 和下水位 限定于此。  Therefore, in the FFO, the water level can be full, up and down, respectively, and the upper and lower water levels. The upper water level FFO is almost full and not full. For example, the upper water level in the FFO has increased to 95% of the FFO capacity. The FFO is about to go down. The water level in the FFO has been reduced to 5% of the FFO capacity. It should be understood that 95% and 5% of this are not limited to the upper and lower water levels.
仍然參照 1， 在需要速率 的 中， 可以增 ， 以 于根 需要 ， 到 X 。 在本 中， 快 FFO的 速率是通 在OP 的 置低 O 的 降低FFO的 速率是通 在OP 的 插 填充 的。 速率 幅度以 FFO 中的 在上水位 和下水位 同力 宜。  Still refer to 1, in the need for speed, can be increased, so that the root needs to X. In this case, the rate of the fast FFO is set at the lower of the OP. The rate at which the FFO is reduced is filled in by the OP. The rate is the same as the upper and lower water levels in the FFO.
于OP 的 ， 其 般有 8 位置， 其中 4介字 位置 送升 ， 3 位置目前是保留的，近有 1 位置可以用 低 O 。 然， 必要情況下， 3 保留字 也可用 ， 但 在 般情況下， 1 已 移用。  For the OP, there are 8 positions, 4 of which are sent to the position, 3 are currently reserved, and nearly 1 can be used with low O. However, 3 reserved words are also available if necessary, but in the normal case, 1 has been moved.
填充 表示 不 于O ，也不是OP 的 ， 在組裝到高 O 中， 的填充 和 常的 O 起 ， 但是在 高 O 出低 O 的 ， 將  Filling means not O, not OP, in the assembly to high O, the filling and the normal O, but in the high O low O, will
剔除。 因此， 需要 下方式 到 X FFO 到上水位 ， 此 需要戶生 (低 O ) FFO 到下水位 ， 此 需要戶生 (填充 )。 在本 中，可以在控制 FFO 的水位 、 FFO 的 出狀 定是否 速率 、 相 的 速率 、 控制 上， 2所示， 可 ， 在上 速率 中， 主要的 接 流程包括 Eliminated. Therefore, the next way to X FFO to the upper water level is required, which requires a household (low O) FFO to the lower water level, which requires a household (fill). In this case, it can be shown in the control of the water level of the FFO, the FFO output rate, the phase rate, and the control, 2, in the upper rate, the main connection process includes
1 FFO 的水位 ， 而可以 FFO 的 滿 。 1 FFO water level, but can be FFO full.
2 的O 能信 ， 把O 到FFO 中。 3 控制 出的FFO ， FFO 。  2 O can believe, put O into FFO. 3 Control the FFO, FFO.
4控制 FFO 的 滿 ， 定是否 速率 。 FFO 滿 ， 需要 ， 快 FFO 的 速率， 而不 出現FFO 滿 FFO ， 需要  4 Control the FFO's full, whether or not the rate. FFO full, need, fast FFO rate, without FFO full FFO, need
， 降低FFO 的 速率， 而不 出現FFO 。  , reduce the rate of FFO without FFO.
5 將 速率 得到的 O 及速率 組裝， 得到高 的 O ， 而完成低 O 到高 O  5 Assemble the rate O and the rate to get a high O, and complete the low O to high O
的 接。 Pick up.
本 的 接裝置， 可以包括  The connection device of the present may include
配置 ， 于根 低 到高 的速率特 需求， 配置相座教量的低 通道教 羊元和先 先  Configuration, low-to-high speed special requirements, configure the low-channel teaching of the teachings and the first
組裝模 ， 于將所有先 先 中的由 的低 通道教 羊 需要理解的是， 此 只是 功能 的功能 ， 非 休 現形式的限定， 在 1 的 中， 就表示了 更 休的裝置 ， 配置 的功能可以 1 的控制 完成， 而組裝模 的功能可以 的 X 完成。 ， 只要涵蓋了上 的功能， 都 視力 于本 的 接裝置。 本 的 接裝置， 的， 可以羊 、 可 輯器件、 集成 、 SP 等硬件 。 然， 通 軟件形式 同 可以 本 的 接功能。 Assembling the mold, in order to understand all the low-channel teachings of the first, it is only the function of the function, the definition of the non-lost form, in the middle of 1, it means the device of the rest, The configured function can be completed by the control of 1 and the function of the assembled mode can be completed by X. As long as the functions are covered, they are all focused on the device. This connection device, can be sheep, editable devices, integrated, SP and other hardware. However, the software form can be connected to the function.
本 現有 木相比， 減少了 O 接所需的步驟， 可以 次完 成低 O 到高 O 的 接， 了資源， 提高了 接效 率。 在FFO中 水位 ， FFO不 出現上 和下 。  Compared with the existing wood, the steps required for the O connection are reduced, and the low O to high O connection can be completed, and the resources are improved, and the efficiency is improved. In the FFO water level, FFO does not appear up and down.
， FFO的 速率不匹配的 題解決方式 ， 效果良好。  , FFO's rate mismatch solution, the effect is good.
以上內容是結合 休的 方式 本 所作的 步 ， 但 只是 于理解而 的 ， 不 力本 的 休 只局限 于 。 于本 木領域的普通 木 ， 在不 本 的前提下， 可以做出各神可能的等同 或替換， 或 都 于本 的保 。  The above is the step taken in conjunction with the way of Hugh, but it is only understood, and the inability to do so is limited to . Ordinary wood in the field of wood, in the absence of this, can make the equivalent or replacement of each god, or the protection of this.
