近代中国边患频仍，边疆因之成为学人关注的重要话题。

The study of frontier became a important topic among Chinese scholars because of frequent frontier troubles in Modern China .

我还记得一只狐梗狗牙龈缘边患上恶性的梭形细胞肿瘤，冷冻笔有效控制了这癌症的病情。

I can recall a case of palliation and regression of a spindle-cell tumour on the gingival margin of a Fox Terrier .

隆庆以后，随着边境互市的兴起，长城沿线边患稍解，商贸活动日渐发达。

With the rise of the border frontier , a little trouble on the frontier along the Great Wall Solutions , commerce increasingly developed .

但在大的历史背景下来看，熙河之役显然是北宋解决西北边患的一次积极尝试。

However , the Xihe Campaign obviously was an active attempt to alleviate the border crisis in northwest areas of the Northern Song Dynasty .
