paper

一是研究课题不新，对现有课题的推进度不大，或是研究课题很新，但从技术推进角度不是很大的发现；

二是国际论文以英文写作为主，但中国一些学术论文的英文写作在语法、拼写上不够准确，在语言表达上不够清晰；

三是论文的形式结构不清晰，不以学术杂志所要求的标准范式进行写作，有些论文字数过多；

四是论文的参考书目不是最新的学术书籍，如果技术论文列出的参考书是1980年代的，编辑显然不会太感兴趣，还有一些引用很难找到出处。

This is documented, albeit obscurely, in "help set term postscript":
In addition to the standard postscript fonts, an oblique version of the
Symbol font, useful for mathematics, is defined. It is called
"Symbol-Oblique".

英语中副词的位置

副词是英语中用法比较灵活的一类词，主要用来修饰动词、形容词或另一类副词。不同的副词在句子中的位置是不同的。以下就笔者所见作一小结。
1．时间副词（now，then，recently，soon， just now，right away，etc．）可以放在整个句子或从句之前或后，并通常放在句末。其中 then，recently可以放在动词之前；still常放在动词之前或系动词、助动词、情态动词之后；而yet常放于句末，并且句子常用否定形式。例如：
I'll then turn to my classmates for help．
When all the students finished the morning exercise，he was still asleep．
We haven't finished the work yet．
2．地点副词（here，there，down，anywhere，everywhere，inside，etc．）和方式副词（well，quickly，kindly，etc．）常放在宾语之后，或不及物动词之后。其中here，there，up，down等副词与不及物动词go，come，stand，walk， lie等词连用时，副词可置于句首。如句子主语是名词或名词短语时，句子需用完全倒装语序。例如：
There stands the tower．
Down came the rain．
We looked for the lost wallet here and there，but in vain．
3．程度副词（very，quite，almost，fairly， nearly，just，extremely，hardly，etc．）常放在被修饰词之前，但当very修饰动词时，常与 much连用并置于句末。例如：
I like her very much．
With one false movement，he nearly loses the whole game．
4．频度副词（ever，never，often，always， seldom，sometimes，etc．）常放在动词之前，或系动词、助动词、情态动词之后。其中some- times也常置于句首。例如：
I have never been to America．
Sometimes he phones me，and sometimes he writes to me．

5．关于副词only的位置。only可以修饰名词、代词、动词、形容词、副词等，通常放在被修饰词之前。但是，当only放在动词之前时，句子可能有几种含义，这就得靠上下文的意思来正确理解。例如：
It was only an coincidence．
They only have coffee in the morning．（可以理解为：他们早上只喝咖啡。或：他们只在早上喝咖啡。）
注：（1）当程度副词与频度副词同时在句子中出现时，程度副词通常前置修饰频度副词。例如：
He hardly ever leaves his house all the day．
The president of our university is nearly always occupied．
（2）当时间、地点、程度与方式副词同时在句子中出现时，常把程度副词放在最前面，方式副词放在地点副词之前，时间副词放在最后。但是，句中动词是动态动词（go，come， leave，arrive， etc．）时，则常把地点副词放在方式副词之前。例如：
They performed pretty well in the city hall last night．
She went home quickly．
（3）可作定语的副词（如here，there，back， ahead，abroad，below，above，yesterday，before， etc．）通常放在被修饰名词之后。例如：
We will see a beautiful picture about the country in the years ahead．
The atmosphere here is seriously polluted．
