近两年,跟着猛犸象牙的热度渐渐消弱,文玩市面上最先泛起另一种远古生物制品——披毛犀牛角。犀角的药用价值人人都清晰,清热凉血、保健防中风结果一流,经济还过得去的家庭根基都邑收一两件,日常平凡可用来把玩浏览,要害还用来入药,一箭双雕。

首先注意掌握的要领是:1、犀角有鱼籽纹,牛角没有;2、犀角虽然可以一层层剥开,但没有一圈圈的角朊层;3、在正常情况下犀角有气味,而牛角没有。一、犀角的鉴定犀角的鉴定不难,但由于犀角十分珍罕,一般人能上手的机会不多,所以不少收藏者和古玩商只好凭着猜测臆断。请看犀角的表面纹路和竹子的纹路很象,故称为“竹丝纹”;但犀角截面又有竹所没有的如同皮肤发囊般的肌理,其斜剖面摸上去有类似皮肤鸡皮疙瘩的感觉,故其纹亦可称“发丝纹”。这纹路难伪造,牛角的仿品和合成的都没有这个特征。亚洲犀角鱼子纹鱼子纹(纹中要有一个小点)和驴蹄子料很像,注意识别真品这种中间有白点的,要用:打灯来看,再磨平鱼子纹,再打灯。如此反复还有的。才是真品。

第一:鱼子纹要明显,要凸出来的那种,而且要通体都有。只要是横切面,要通体都有。纵被磨平处,打灯里面也有。

第二:竹丝纹必须明显,也是通体都有。

第三:斜面变化鱼子纹要明显。也是凸出来的拉长的那种。(这种市面上目前没有见到过高仿品作这个纹的)

第四:气味上,平时是没有什么气味的。要磨一下,才有,是淡淡的清香味。没有腥嗅味,如果一闻就有气味的,多为仿品,有中药味,有腥臭味等,有麻油香味的,都是假的。只有没有味的。才有可能是真品。如果放在盒内,再拿出来的,就一闻才有味。但是世人没见过,不知其味如何。所以此点,要专业人员才可以凭味断犀角。否则很难。或者要有标准样本进行比较气味。第五:重量是很轻的。质地轻,可能一立方厘米才一克左右。好好想想。试算算他的体积是多少,与他的重理相符吗?动不动就上千克、上几百克,岂不可笑。上千克的都快整支角了。犀角杯,多为几十克,多的就百多克,没有很重的。

第六:打灯看,这个不用我介绍了吧,都是打灯看了,再磨平,再打灯看,有没有孔状鱼子纹。这个方法是专家们通用的方法。不用介绍。应明白。

The IMF's emergency financing for 70 countries is very fast-disbursing and does not carry traditional conditionality, a spokesperson said.

WASHINGTON, June 19 (Xinhua) -- The International Monetary Fund (IMF) has said it is expected to deploy emergency financing for 70 countries by Friday as the COVID-19 pandemic continues to ripple across the globe.

IMF spokesperson Gerry Rice said at a virtual press briefing Thursday that "tomorrow we expect that number to be 70, so 70 countries supported by the IMF with emergency financing roughly about 25 billion dollars."

"This emergency financing is very fast-disbursing, countries receive the money within days, it does not carry traditional IMF conditionality," Rice told reporters. "It is money to be spent on paying for things like nurses' and doctors' salaries, and equipment, and medical equipment to deal with the crisis."

For the Asia and Pacific region, seven countries have received emergency financing totaling about 1.5 billion dollars, Rice said.

And in Sub-Saharan Africa, 28 countries have received emergency financing totaling almost 10 billion dollars, Rice said, noting that the figure is much higher than the IMF's average yearly lending of 1 billion dollars to the region.

Over 100 countries have asked the IMF for emergency financing amid the pandemic, and the multilateral lender said earlier this year that it had doubled access to its emergency facilities to meet the expected demand.

In mid-April, the IMF projected in its World Economic Outlook that the global economy was on track to contract by 3 percent in 2020 as a result of the pandemic, calling it the "worst recession" since the Great Depression in the 1930s.

IMF Managing Director Kristalina Georgieva said in May that the multilateral lender would "very likely" further cut global growth forecasts, as incoming data from many countries was worse than the IMF's "already pessimistic projections." The updated forecasts will be released next week.
