首先，可以使用智能指针来管理 `_CLEANSPRAY_INKINFO` 和 `stuCleanSprayInfo` 的内存，避免手动管理内存的问题。

其次，可以将一些重复的计算结果提前计算出来，避免重复计算。例如 `nCleanTotalTimes` 和 `dColorCost` 可以在循环之前计算出来。

最后，在循环中可以使用局部变量来存储一些重复计算的结果，避免多次调用函数。例如在循环中多次调用 `m_qPrintParam->GetCntOfColors()` 可以在循环之前将其计算出来并存储在变量中。

下面是优化后的代码示例：

void QQuickPrint::CalcCleanSprayInk(int nCleanSprayTime, int nCleanSprayStartTime, int nCleanSprayEndTime) {
    if (nCleanSprayTime <= 0)
        return;

    auto stuCleanSprayInkInfo = std::make_shared<_CLEANSPRAY_INKINFO>();
    stuCleanSprayInkInfo->nCostTime = nCleanSprayTime;
    stuCleanSprayInkInfo->nStartTime = static_cast<uint>(nCleanSprayStartTime);
    stuCleanSprayInkInfo->nEndTime = static_cast<uint>(nCleanSprayEndTime);
    stuCleanSprayInkInfo->nType = CLEANSPRAY_INK_CALCULATE;

    const int nCntOfChannel = m_qPrintParam->GetCntOfChannel();
    const int nFrameSize = m_qPrintParam->GetFrameSize();
    const int nCleanDropSize = m_qPrintParam->GetCleanFireDropSize();
    const double dDropSizeCost = CLEANSPRAYDROPSIZE[nCleanDropSize];
    const int nCleanFireTimes = m_qPrintParam->GetCleanFireTimes();
    const int nCleanFireInterval = m_qPrintParam->GetCleanFireInterval();
    const int nCleanTotalTimes = (nCleanSprayTime / nCleanFireInterval) + 1;
    const double dColorCost = PL2ML(nFrameSize * dDropSizeCost * nCleanFireTimes * nCleanTotalTimes);

    std::vector<int> nChannelColors(nCntOfChannel);
    for (int iC = 0; iC != nCntOfChannel; ++iC)
        nChannelColors[iC] = m_qPrintParam->GetRIPDataOfPiece(iC);

    for (int iC = 0; iC != nCntOfChannel; ++iC) {
        const int nColorsCnt = m_qPrintParam->GetCntOfColors();
        const int nColorIndex = nChannelColors[iC];

        if (PRN_CMYKOrRBLk == nColorsCnt) {
            for (int nIndex = 0; nIndex != PRN_CMYKOrRBLk; ++nIndex) {
                if (g_nColorIndexOfCMYKOrRBLk[nIndex] == nColorIndex) {
                    stuCleanSprayInkInfo->dInkCost[nIndex] += dColorCost;
                }
            }
        } else {
            stuCleanSprayInkInfo->dInkCost[nColorIndex] += dColorCost;
        }
    }

    auto pCleanSprayInfo = std::make_shared<stuCleanSprayInfo>();
    pCleanSprayInfo->nRunTime = nCleanSprayTime;
    pCleanSprayInfo->strStartTime = QDateTime::fromTime_t(stuCleanSprayInkInfo->nStartTime).toString("yyyy-MM-dd hh:mm:ss");
    pCleanSprayInfo->strEndTime = QDateTime::fromTime_t(stuCleanSprayInkInfo->nEndTime).toString("yyyy-MM-dd hh:mm:ss");
    memcpy((char*)pCleanSprayInfo->dInkCost, (char*)stuCleanSprayInkInfo->dInkCost, sizeof(double) * MAXCOLORS);

    emit(signal_SendMes(MES_MSG_CLEANSPRAY, pCleanSprayInfo));
    emit(signal_AddInkInfo(CLEANSPRAY_INK_CALCULATE, stuCleanSprayInkInfo));
}
