		if (sourceLen < 1)
			return "";
		StringBuffer pinyinStrBuf = new StringBuffer();
		for (int idx = 0; idx < sourceLen; idx++) {
			String[] tmpData = PinyinHelper.toHanyuPinyinStringArray(sourceStr
					.charAt(idx));
			if (tmpData != null && tmpData.length > 0
					&& tmpData[0].length() > 0) {
				if (isUpperCase) {
					pinyinStrBuf.append(tmpData[0].substring(0,
							tmpData[0].length() - 1).toUpperCase());
				} else {
					pinyinStrBuf.append(tmpData[0].substring(0, tmpData[0]
							.length() - 1));
				}
			}
		}
		return pinyinStrBuf.toString();
